Votre iPhone 4 ne tient plus la charge ? Remplacez la batterie ! Heureusement, le remplacement de la batterie sur l'iPhone 4 nécessite un démontage minimal.

Si votre batterie est gonflée, prenez les précautions appropriées.

Pour des performances optimales, après avoir terminé ce tutoriel, Calibrez votre batterie nouvellement installée: chargez-la à 100 % et continuez à la recharger pendant au moins deux heures. Ensuite, utilisez votre iPhone jusqu'à ce que la batterie soit faible et qu'il s'éteigne. Enfin, chargez-le sans interruption à 100 %.

Vidéo d'introduction

  1. Avant de commencer, déchargez votre batterie iPhone en dessous de 25%. Une batterie lithium-ion chargée peut prendre feu et / ou exploser si elle est perforée accidentellement. Éteignez votre iPhone avant de commencer le démontage.
    • Avant de commencer, déchargez votre batterie iPhone en dessous de 25%. Une batterie lithium-ion chargée peut prendre feu et / ou exploser si elle est perforée accidentellement.

    • Éteignez votre iPhone avant de commencer le démontage.

    • Sur le boîtier arrière de votre iPhone 4, il y a ou bien deux vis cruciformes #000 ou bien des vis Apple 5 points Pentalobe (deuxième image). Vérifiez de quelles vis il s'agit et assurez-vous d'avoir le tournevis qu'il vous faut pour les enlever.

    • Enlevez les deux vis de 3,6 mm (Pentalobe ou cruciforme #000) près du connecteur de dock.

    • Assurez-vous que le tournevis a une bonne prise lorsque vous retirez les vis Pentalobe, car elles dérapent très facilement.

    Caution: New phones may contain T1 screw heads instead of Phillips.

    any news on those screwdrivers? where can we buy them?

    using something like the 18-compartment tray will GREATLY help with this one; there are over a dozen groups of parts. For re-assembly having a digital calipers to measure the 2.4 vs the 2.6mm screws also helps greatly.

    My method for hardware management during delicate phone surgery is to take and print out on 8.5"x11' paper, one or more pictures of the open phone in various stages of disassembly, and then tape the screws to the appropriate spots on the pictures. Also write numbers on the pictures next the screws to indicate the order in which you removed them.

    I use a plastic egg tray, I drop all the screws and small parts (like the camera) for each step into the same egg indentation. You can see that the screws are different lengths, so I don't put one screw into it's own spot. I used 5 egg indentations to replace my screen.

    I did a successful surgery on my iPhone, be warned this is not for the faint of heart!

    I've changed some iPod screens as well and that has been the least pleasant experience so far. Glue and the main connector that has to be unwrapped and connected from the rear where you have no feel or control where it belongs.

    iPhone repair is complex, but doable and has very few "traps".

    Couldn't even get both screws out of the bottom of the case. One was easy and other refuses to budge. Screws so small I can't see if it is turning or screw driver is properly seated. Sad I too have done screen replacements on other phones. Don't know any secrets to get the screw out

    I also have a problem with seeing what is happening with some of those tiny little screws and parts. For other projects that I do, I use an Opti-Visor. It slips over your head and provides 10x magnification. ( You can find them on Amazon).

    Yeah, it adds cost to the project and you would have to wait for delivery, but it sure makes a world of difference in seeing what you are working with / on.

    On an early iPhone 4 I found that the #000 Phillips bit included in the 54 Bit Driver Kit didn't actually fit the screws. However the JIS #000 also in the kit did fit quite well. This is due to the JIS bits "thinner" design to prevent camming out of the slot. Otherwise everything went well. Looking forward to replacing the battery in my other phone that has the pentalobe screws. Glad I got the 54 Bit kit!

    For organisation of the parts and for a much easier process of rebuilding i use a big magnetic flat surface with a grid drawn on it. Then I use a dry erase marker to make any notes I need and to number the parts in order as i disassemble . Believe me it saves a lot of time and hassle especially if you drop one of those tiny screws good luck finding it but when your working over the magnet and drop a screw its going to be right where it fell. At first I tried the piece of paper to keep organised but all it takes is one small slip and you move the paper too quick and your left with a jumbled bunch of screws and parts and a painstaking task of putting it all back correctly, aka a big waist of time and effort.

    case-yg - Réponse

    I found it very useful to use a magnet sheet when doing these repairs. I use electrical tape or a sharpie to make a grid, and place each micro screw in a separate box on the grid.

    I work directly over the magnet sheet, so that if something drops I have a better chance at not losing it.

    If you do lose a screw, go over the work area with a fridge magnet. It will pick it up if it hasn’t popped too far away.

    If the screw head is not buggered, press the tip of a hot soldering iron to the screw for a second or two. Don't get it too hot, or you'll damage something.

    don't use hot soldering iron . the female outlet the battery plugs into is very fragile . for no extra money you can buy a battery that has magnetic tools specifically to pick this screw out . if worse comes to worse be certain the screw will come no looser then use tweezers and pick it out . the #1 fear with this technique is DO NOT DROP THE SCREW .

    Just be careful when removing the battery with the plastic pull tab. On some units, they use so much glue that it's virtually impossible to take the battery.

    In such an instance, you could use the iPod opening tool to assist (just be careful where you stick it!)

    use the iPod opening tool to pry gently under the battery from the outer edge of the phone and work towards the plastic tab. the tab is not actually attached to the battery itself, but a plastic sheet between the battery and inner frame. the adhesive on the battery tends to be under the edge of the battery nearest the center of the phone.

    My battery was so firmly glued in, it took a long time to slowly pry it loose. Patience is the key to this process. I could see easily damaging the circuit board by using too much force. The plastic tab did not help at all.

    The ribbon cable attaching the new battery to the battery connector clip is longer than the original. I clicked the clip into the socket first and then was very careful to fold the excess while putting the battery back in so the ribbon cable didn't kink. One kink in this could sever the battery leads.

    drathbun - Réponse

    My ribbon cable was also longer than the original. How did you get it to not kink while placing the batter back into the phone? That seems to be my only hang up at the moment

    cvbaseballsean22 -

    Piece of cake! The hardest part was being sure the outer pentalobe screws were actually turning and I wasn't stripping them. Battery was glued firmly in, so I loosened it from the outside instead of using the plastic pull-tab. I pre-bent the battery connector neck before putting it back in and had no problems with it fitting in. Getting the battery connector aligned with the antenna piece underneath was a bit fiddly. Got the case back on, put in the new screws, and powered the phone on without problem. Had 40% charge, all seems well. Yippee!

    chezbuttons - Réponse

    Do NOT use a spudger or similar type of prising tool to try lift up the battery. Instead, just warm up the whole area with a hot air gun or hair drier to soften the glue.

    The reason why I say don't use an implement to try lift the battery is because far too many times I've seen punctured & bent batteries come in to this workshop that have to be thrown out for safety reasons. It only takes a grain of sand, or a burr on the spudger and you're risking a potential cell rupture and potential fire.

    Just use a bit of heat ( not a lot! ) to soften up the glue and it'll come away with the plastic pull tab.

    Paul L Daniels - Réponse

    These instructions don't mention putting the 2.5mm screw back in. I found this very challenging because it is so short, so very difficult to line it up to get it back in the hole, and very easy to drop it inside the phone. Take care.

    Apparently it's not necessary to remove the battery, but try at least (I'm curious).

    The battery was stuck (too much glue) and the plastic tab didn't help, and I ripped it...

    So I use the plastic opening tool on the other side to remove really gently the battery, it was really really stucked with the glue... Now I'll know when I'll need to change it.

    I put a little piece of tape to repair the plastic tab for the next time.

    Adhesive was holding battery VERY firmly, so during this step I used a hair blow dryer on low setting to carefully heat up the device. Then used the plastic tool to gently but firmly pry up one place on each edge. At first it felt like barely anything was happening, but within a few tries the adhesive gave away easily and the battery came right out.

    The new battery from iFixit already had the cable properly folded, but before inserting the battery I used the plastic tool to press the fold closer to the battery body.

    misc - Réponse

    Before inserting the battery I put the contact clip into position. It has a hooked shape on one side which fits between the socket and the folded battery cable. If you try to position it AFTER the battery is installed the whole process is much more difficult. I used a tweezers to hold it in place while inserting the battery.

    misc - Réponse

    When inserting the battery I started by guiding the folded cable into position against the side of the contact clip, then proceeded to lay the battery in position. This made it very easy to have all parts in their original positions -- no need to fiddle with the battery cable or contact clip afterwards.

    misc - Réponse

    When pressing the battery connector into the socket, the first time I pressed from bottom to top. That didn't work because there is a little tab at the top of the connector which must fit into a tiny notch or else the connector won't lay flat properly. Pressing the connector from top to bottom worked easily.

    Needle-nosed tweezers were very helpful when lining up the screws. After everything was reassembled I tried powering up the device, but the battery had insufficient charge. I plugged it in and immediately the screen displayed a battery with a thin red line (illustrating no charge). After 25 minutes the device sprang to life and indicated a 10% charge. At 70 minutes the battery indicated 30% charge, and at that rate should be fully charged in under 4 hours. It's fixed!!

    Strictly speaking re-assembly is NOT the exact reverse of dismantling. In particular do not put the battery in and then try to plug in the connector, Rather, start by plugging in the connector (having straightened the ribbon-wire attaching it to the battery) and only then re=position the battery on its (gluey) base. Also I used a wooden cocktail stick to position the antenna connector correctly (pushing the stick through the hole in the antenna piece and into the threaded base where the screw will eventually go) and then I held it all in place (temporarily) with a tiny blob of Bluetac until I managed to successfully withdraw the cocktail stick and fit the proper screw.

I used "flat" 1mm screwdriver instead of 5-Point one with success.

jacek - Réponse

When I put the battery in, the lead going from the battery to the plug was fully extended. You need to fold it back on itself - look at the shape of the battery you just removed.

Unfortunately, I didn't realize this until AFTER I clipped the new battery in. I tried to align the battery to where it should go while it was still connected, in the process I broke one of the soldered connections on the battery connector. Wouldn't boot up and did the continuous battery recycling.

Luckily, I was able to put the old battery back in and all was working again. I don't think I'll attempt a new battery at this point...

Hugely disappointed. iFixit sends me a battery that has corrosion on it with a black X marked on the clip, looks like it is used? And don't even mention this small part, or the folding over. C'mon iFixit you've done great stuff this is not one of them.

Now that I put my old battery back in, my phone turns on but won't charge. Great. I have 68% until I have a dead phone, no battery. The battery I got from ifixit was a dud. This is a complex process--I've changed out displays on a laptop, hard drives, cpus. This is NOT a "moderate" job and needs major rework on their tips.

dprossi - Réponse

I too got a dud battery from Ifixit. They would not replace the battery. Why… because putting in the new battery the tab coming from the battery fell off. So they used the excuse they could not check whether it was good or bad. Had to send back the battery and the repair kit to get a lousy 8.50 credit. Which the battery and repair kit and shipping cost me over 23.00 dollars plus had to pay the return postage.


Beware, watch the video, there is a antenna cover/clip that pops out easily when you remove the inside screw and has to be replaced. This was quickly mentioned in the video but NOT mentioned in the guide. Also I stripped every screw I removed/replaced, the #00 screw driver doesn't work to well and I had the original philips screws, not the pentalope screws. Also, the read all the other comments, I wish I had known the battery cable wasn't pre-bent...its tricky doing yourself.

Be careful is my word of advice and have tweezers around too!

cdthacker - Réponse

This took much longer than the expected 10 mins. The guide made no mention that the battery cable wasn't pre-bent, and I almost bent the cable at the wrong angle to make it fit during several attempts. I tried to re-start the phone several times without success before finally making the new battery work properly.

The battery change worked without any problems.

My replacement battery connector cable was pre bent so that was not any issue for me.

1) The screws are very easy to strip. Use a magnifying glass to examine the heads and make sure the screw is actually turning. If you do strip the screw, you may still be able to remove it using a 1 mm flat screwdriver. NB the screwdriver sold on the ifixit site worked well for me removing the two screws that hold the case together, and failed utterly removing the screw that holds the battery clip in.

2) clean the pressure contacts on both the new battery and the phone using windex or rubbing alcohol and a q-tip. Make sure not to leave any cotton fiber behind.

3) The battery ifixit sent me had literally zero charge, and as a consequence it looked like the phone wasn't working. The screen was black and would only wake up when plugged in to the wall. This caused me lots of anguish and I ended up putting the phone together and taking it apart again three or four times. But once I let the new battery charge for 30 minutes it came to life and was fine.

Successful installation.

STEP 4: When removing the battery connector screw, I had to use heavy downward pressure because of heavy thread-lock applied to the screw during initial assembly. Battery supplied contained ~33% charge, which is normal for new batteries.

Phone powered up immediately when plugged in and is charging. Barring the new battery turning out to be somehow defective, this install was a complete success.

bwhoback - Réponse

Followed instructions to a T. New battery would cause reboots and CRC errors in the logs every 3 minutes or so.

Turns out the battery I got on eBay for this is defective as it would not charge. After replacing it back with the original Apple battery, no more reboots. I noticed the new battery was not charging as there is no lightning icon in the battery bar on the iPhone 4 screen when it was plugged into the adapter, it only showed that it was plugged in. The original battery has a lightning bolt icon in the battery bar, indicating it's charging when plugged in.

Thanks iFixit! Great instructions! Too bad my replacement battery from eBay does not work...

The pressure sensor kept popping up a bit as I worked on the connector, and I wasn't sure if that was part of the tab I was supposed to leave alone. When I did get the battery out (I had to pry it out with one of the plastic shims) the pressure sensor went with it and for a moment I thought I had just destroyed this phone. Fortunately I replaced it and set the new battery, and the phone booted.

oahazmatt - Réponse

Ich habe die Batterie und den Home-button ersetzt und brauchte 1,5h dafür. Alles funktionierte.

Aber danach kam jedesmal nach circa 2 Minuten ein Reset und das iPhone bootete neu.

Das iPhone-Konfigurationsprogramm zeigte folgendes:

<Error>: CLTM: could not find Temperature property

<Error>: watchdog: did not receive thermal notification in time: 0x000003fe

In den Einstellungen, Allgemein, Info, Diagnose & Nutzung, Diagnose & Nutzungsdaten: CRC ERR!

Grund: Keine Kommunikation mit dem Temperatursensor im Akku. Dann WDT Reset.

Akku nochmals vorsichtig ausgebaut, die Buchse vom Mainboard hatte sich komplett gelöst!

Ich konnte die Buchse wieder anlöten, 4 Pins, aussen 2 für Spannung, innen die Daten.

Funktionierte nicht. Unter dem einen abgerissenen Datenpad ist ein 0,15mm Via, dass ich auch noch kontaktieren musste!

Jetzt kommt wieder z.B.: CLTM: stale battery temp: now = 1359865173, lastupdate = 271

Auch die Batterie selbst könnte defekt sein in einem solchen Fall.

Ich hoffe das hilft anderen :-) Gruss MartinW

WoW! Just finished replacing my iPhone 4 battery and I'm both relieved and impressed that it really was as simple as your site said it would be! There was a sketchy moment or two with the antennae piece but it all went pretty smoothly! This sure beats paying someone an outrageous fee to change the battery when it's easy to DIY!!! Thanks ifixit!

okhoosier - Réponse

From the tools list it seems as though the 00 driver is the one needed for the battery connector screw and the 000 is only needed if the external screws have been replaced. I ordered only the 00 driver which does not fit the battery connector at all. Luckily I had an eyeglass driver on hand that did the job. Which driver is required for which screws should be more clear.

I did my battery today. It was easy. Battery was completely dead when I put it in, so I retried my old one to make sure I didn't mess up the install, then reinstalled the new one. After I plugged it in about 10 minutes, I finally got the charging indicator and 5 minutes after that, it turned on with the charger connected. My original battery was VERY glued in and took a bit of careful prying. It took about 4 hours to get to 100% charge. Very pleased with the outcome so far. I will update if I have any problems, but hopefully not!

This is a great guide! IMO the hardest part is getting the battery connector on the new battery in place. The plastic connecting the battery connector to the battery has to be very carefully folded and tucked between the battery and the pressure contact, all while keeping the pressure contact in the right place. (Use the old battery as a guide) Anyways, overall an awesome guide and very happy with the kit!

huybui75 - Réponse

The guide makes the process a piece of cake. The reassembly of the antenna connector should be shown in more detail. After closing the lid and pressing the top button, reboot started immediately and the SIM unlocking process went for a long (too long) time. I rebooted completely and everything came back to nominal.

jeagauthie - Réponse

Well, the process is not nearly as easy as the demo might suggest. Pay attention to the issues around proper screwdriver size as the screws are very easy to strip, especially the battery connection screw. Warming the glue behind the battery with a hairdryer really helped immensely as the battery was then easier to pry up and remove. Because of the short length of the battery connector screw, having a tweezer and magnifying glass helps. If your screwdriver is not not securely slotted into the head of the screw, make sure it is before you try to remove and re-install it. Unless you have patience and read the comments here carefully, your chances of experiencing a glitch are high.

Sarah - Réponse

Just completed. Mighty fiddly to work on. Only tricky part is re-positioning the battery connector so that all the items are flat and aligned for the screw to secure it. Used the plastic opener to help lift the battery out. You can hear the glue slowly giving up.

30 mins from start to finish. Now charging up. Thanks.

Alastair Dodwell - Réponse

I used your great kit, followed your helpful directions, and powered the phone back on while charging the new battery. The phone then indicated for about the first 20 minutes that it was "searching" for a cell signal even though it was able to use the cell network. (I made and received a call during this "searching" time.) It showed a strong wifi signal as usual; that also worked fine. This "searching" indicator problem just cleared up on its own. Once the indicator switched to show the usual 3G cell signal, the problem went away. Powered down and restarted, and after a couple seconds it showed the usual 3G cell signal. Now all seems well. Thanks much!

I didn't get the guide, but just ordered the battery and screwdrivers, and watched the video (gotta say I like MJ - a no-nonsense woman...). I am not sure what all the issues are that are listed here - my repair went fine (though I did have a little bit of issue with the antenna that folks mentioned as well, but eventually it seemed to go into place). I gave the repair about a 50/50 chance of succeeding, but didn't really have much to lose, as my previous battery was barely lasting a couple of hours. When I reassembled it, voila, it worked fine, had about 33% charge. I have since used it for 2 weeks, and the battery life is almost like new, and everything works just fine. Thanks, ifixit!

The hardest part was getting the inside screw back on! If the Phillips screwdriver were magnetized, or if I'd had a pair of long tweezers, that would have gone a lot easier. But my phone no longer shuts off if I use it for more than a minute without connecting it to a power source. ;-)

I worked in the box to keep errant screws from getting away, that helped a lot. I also have one of those floor lamps with a magnifier, which helped as well. But I gotta say, MJ must have pre-loosened the battery connector in that video. It sure didn't lift off that easily for me.

Guys, I replaced Battery on my good-old iPhone 4, everything went well, the phone turns ON, but won't charge. It shows charging indicator, but keeps rebooting while connected to charger.

Denis - Réponse

It went alright.

It would have been very helpful to have the above step by step instructions include the process of actually installing the battery, not just removing it.

I added a piece of double sided adhesive tape to the battery and the phone for extra stability.

It was confusing to figure out on my own how to align the battery antenna to the connector. As was stated above, there is extra play on the battery antenna which makes it confusing to align in it with the connector board.

If the above step by step photos and instructions took us all the way through the process that would be the best.

Also, for sure a pair of tweezers in the Liberation Kit would be helpful.

My battery replacement went without issue (overcoming the adhesive holding the battery in place was a chore). When I attached the power cord it went into a repetitive reboot cycle - the apple logo would come up for a while, it would vibrate twice, go dark, and then repeat the cycle. I got it into reset mode and connected it to iTunes but the restore would error because the iPhone was not responding. I thought I might have damaged something so I opened it back up removed the new battery and inspected everything. All looked well. I put the battery back in and tried the restore with the same result. Based on everything I read here, I left the phone charging several hours. When I came back I tried the restore and this time it responded, the restore went through, and the iPhone is up and running.

I ordered a replacement kit off of eBay for about $4 and some change. The pentalobe screwdriver worked great. The driver for the battery connector sucked. It would not work. It just didn't fit, and it may have damaged the screw head. I order the ph000 driver from iFixit and it worked great. There is a $5 coupon code (do Google search), and the $10.95 (item + shipping) came out to $5.95. Someone elsewhere said a precision screwdriver set from Dollar Tree worked, but as the head may have been damaged, I just went with the iFixit driver. I was able to change the battery, but am still running into snafus. Initially, the phone booted into ??DFU. The screen said plug into iTunes. I tried the other original battery. Same thing. It finally booted normally, but it was stuck on searching for signal. No cell signal was shown. After putting in the new battery again, it finally booted somewhat normally. The batter percentage showed 73%, which didn't make sense as it was nearly empty moments before.

Hi there! If you don't have a spudger, opening card, or opening picks, try using an old plastic gift card, or a thing plastic tool to carefully pry under the battery. If the battery is very stuck, use an iOpener, or a hairdryer for about a minute to warm the adhesive, and try prying again. Good luck!

Jennifer - Réponse

You may want to open it again. Check if your new battery has the same APN- number as the original one (I got this wrong and my iPhone went crackers after a few weeks), carefully undo battery connector, clean with alcohol (IPA) or the like, reconnect and fix without touching with bare fingers, clean backside of battery connector as well, make sure the protruding spring connector for the back panel is bent up far enough to reliably touch the back panel contact spot (clean!), reinstall back panel. If it still doesn´t work with your new battery, try going back to the original one just to see if this was the cause. If it still does not work, you may have damaged the socket on the main board or unintentionally undone another connector.

Michael Scott - Réponse

Replaced the battery at the same time as a broken display, home button, and a fidgety dock connector. Got the battery from iFixit. Everything worked ok, though the iPhone seemed significantly more sluggish opening apps. After five weeks, a cold phone said " iPhone needs to cool down..." then began constant reboot every few minutes it had been up w/ Apple logo but not progress bar. Diagnostic info showed recurring kernel panics ("bug code 110") as reboot cause. Escalated through reboot, recovery, restores all the way to complete new and minimal installation. Cleaned and checked battery connector. No fix.

Last resort: swap back to the old battery - BINGO!

Finally found out that Apple uses more than one battery type for each iPhone model. Obviously, the iFixit battery did mechanically fit, but not logically. Ugh!!

And the lesson is: before replacing, open the iPhone, check APN-number on battery and order EXACTLY that one for replacement. Make sure you really get a new one. Lots of old junk on sale!

Reading the comments & learning from others who did this was as important as the ifixit guide (which is a really good guide, compared to the others I read). Thank you for making this available! Local service & repair guys told me I had to have Apple people replace my battery. I ordered one from amazon, along with a new back cover (mine was shattered from flying off the dashboard during a turn & crashing on pavement). Both the battery & the cover looked exactly like the originals & included all tools & replacement screws. I was hesitant to attempt the repair but if I paid Apple prices, we wouldn't eat this week. I read the ifixit guide all the way through twice & ALL the comments before starting. The best advice was in Comments, about the battery connector needing to be bent before installation. The whole thing took less than 30 minutes, the screws didn't strip, &everything connected smoothly & correctly, thanks to this ifixit website. The battery was good & I have had NO problems since I did this repair.

Take your time to fix the battery and add the components properly. It took me longer than 10 minutes because I was overly cautious, but it worked.

The little clip you are supposed to take out first gets replaced with the new battery. The new clip was not pre-bent, but I studied the old battery that I took out and made it look exactly the same. I bent it a little and it fit like a glove.

After I added all the parts, I took a Q-Tip with Windex on the end, and cleaned the metal parts my greasy fingers touched, and it dried right away. I was able to clean out the camera part while I was in there.

Video instructions were easy to follow and installation of battery went smoothly so that the phone powered on successfully. However the battery connector metal plate and the immediate surrounding logic board are very disconcertingly hot to the touch and remains quite warm even when the phone is powered off (it's not connected to the charging cable as well).

Prior to install, phone went completely dead as a result of the OEM battery failing. Checked to be sure that iFixit's battery replacement is the correct model which it is. Anyone have feedback would be greatly appreciated. Concerned about potential fire hazard so battery will be removed until either's customer service advises solution or someone in the forum responds with some sort of resolution.

Yoda - Réponse

This was easy. I had watched several different videos before I started and the results were very good. Here are a few tricks I picked up:

1. Have a lot of light to see the small parts

2. After removing the back cover, remove the Phillips screw that holds the battery connector and pay attention to the orientation of the hold down clip on the battery connector.

3. The old battery is glued to the back of the phone housing so use the pry bar/spudger to pry up on the battery on the side away from the connector and the top and bottom. Then pull up on the plastic tab to lift the battery up and out.

4. When you place the new battery in position hold the battery in your right hand above the phone case and clip in the battery connector in first with the battery up on an angle to the right side. When the battery is clipped in place, accordion the flex connector and place the battery in where it goes.

This was easy.

About repairing tiny tech tools:

It can take a lot of time to orient one's perception to such a tiny and precise 3-D "operating theater," especially adjusting one's tactile sensation to a fair level of precision! Be kind to your self; if you're too hurried, and perhaps !#^&@@ off at loss of convenient function of a costly tech-tool, that, like all created things, is subject to Entropy ( the natural progress through time towards disorder), you very well might do damage to the tiny fragile components inside. ..... I mean in the PHONE, right?

I use a small speaker-magnet, or any small magnet. The screws stay put, while I plead with, or yell at other phone-stuff. By the Way... use no rare-earth element magnets; they won't let go of the screws, which can therefore fly out of your hands! Ah, the site says "too long!" A successful Blather! I have enjoyed this!

The instructions make it clear what to do. But, if this is your first time to do this then I strongly recommend reading the comments below placed by others before you start on this project. Review the instructions several times before starting and have them handy as you do it. Take your time.

I found it easier to connect the battery and then set it into place, else you can find yourself fighting with the the battery connector. Not every phone battery is glued in place exactly the same. Wife’s phone battery did not want to come out, fought me the whole way. My phone battery popped out easily.

Also, check the tool kit before you start. I had fortunately ordered two batteries and two Fix-It kits - good thing - because one kit had three Y000 bits and no P2 Pentalobe driver.

Michael Grabbe - Réponse

The job is moderately easy with the correct tools. Having to improvise takes more time to get it right. All instructions are correct and I completed the task pretty quick using an eye loupe (5X) and a 1 MM flat screw driver. Everything went back together OK even with the sealing compound on the screws. I would give you a B+ for your work. Emphasising using the correct tools might help a little . All in all, if you have worked on computer motherboards and such, this job should go well for you. Make sure you have a newspaper or rubber mat under your work to catch the screws. They will jump out and fall if you work too fast. Good Luck! Bob

It seems to snap in correctly, but all i get is the flashing Apple logo. I tried a hard reset, the iTunes button came up, but nothing else, then back to flashing. Anyone?

This is utter madness. IMPOSSIBLE to reinsert that tiny antenna contact thing…, the battery connector won’t line up….TAKING TO APPLE STORE TO HAVE A PROFESSIONAL do it. That video is pretty close to nonsense….she takes out a tiny something and NEVER puts the damned thing back in! Gosh guys, for real????

Figured out why - the battery won’t seat so it won’t go in. MY battery has 2 tiny screws and this battery has one and the screw hole on your battery is not in the correct spot either. Do I have a special battery??? Please advise.

Hi Robby, it’s possible that you might have an iPhone 4S, not an iPhone 4. Check out our iPhone 4S battery replacement guide. Unfortunately iPhone 4 and 4S batteries are not compatible, so you’ll have to contact customer service if you ended up with the wrong one. Hope that helps!

Battery arrived as expected, cable is not bent but fully flat and stiff. Attempted to match bend of original battery to as to be able to install it into the device. First bend of cable de-laminated copper wires at the battery end of the cable coming out of the battery. Finished installation just in case what I was looking at that appeared to be bare copper was maybe just missing paint. No go, only does the flashing Apple Logo and never boots or will not even do the Factory Reset. Reinstalled old battery which at least allows for booting the device again. This appears to have been mostly a waste of $15.00 except for the nice little tool set that I know I will get additional use out of. Review of the return policy has me wondering if it will be of any value to attempt an exchange or return…..since I was the one who bent the cable…..

Dear ifixit, I followed your guide and instructions for replacing the battery on my iphone 4 and I did the replacement in just 10 minutes successfully. Thank you very much for the very clear and neat instructions. I am 71 years old and I assure you that so far I spent a lot on mobile repairs by technicians but from now on I can trust only myself and your technicians only. Once again thank you very much.

My battery had started swelling so I decided to replace it. It turned out to be a very simple procedure. Thanks iFixit!

so, I discovered that the last person who tried to replace the battery didn’t use the right screwdriver holding the battery in place - does anyone have any ideas about how to get that small of a stripped screw out that holds the battery in… thanks. Will

Disassembly and reassembly went well and quickly… however…

When I plugged in my old iPhone (hard restart), it already claimed 61% even with a brand new battery. It also thought it was 6 years in the past, and couldn't sync with any wifi signal. I re-installed my old broken battery, and everything was back to normal. So I re-re-installed my fancy new battery and: 61%, December 31, 2012 on the calendar, and no wifi. Also, I can't unplug it, or it dies, even after 4 hours on the charger. I think I might have wasted $25.

For Will Knapp: If you have a selection of driver bits for your driver shank & handle, try different bits not intended for that Phillips or Pentalobe or other fit on that fastener. Also try angling the driver with various driver bits, to get a grip on the stripped head. This is good to try on any fastener with a stripped head. And use extra pressure to get a grip, before applying torque.

Battery solder clip broke off trying to bend clip in to place - wasted money
