Introduction

Votre batterie se décharge trop vite ? Vous êtes obligé de recharger votre S7 plusieurs fois par jour ? Ce tutoriel vous montrera comment retirer la vieille batterie de votre S7 et la remplacer par une nouvelle.

Le tutoriel vidéo recommande d'enlever la carte SIM. Cette étape n'est pas nécessaire, mais n'aura pas de conséquences négatives sur la procédure de réparation.

Avant de démonter votre téléphone, déchargez la batterie au-dessous de 25 %. Une batterie lithium-ion chargée peut prendre feu et/ou exploser si elle est accidentellement perforée.

Si votre batterie est gonflée, prenez des précautions appropriées. Dans ce cas, ne chauffez pas votre téléphone. Si nécessaire, vous pouvez utiliser une seringue ou un compte-gouttes pour déposer de l'alcool isopropylique (à 90 % ou plus) le long des angles à l'arrière du téléphone pour ramollir l’adhésif. Une batterie enflée peut être extrêmement dangereuse, portez des lunettes de protection et faites très attention, ou faites appel a un professionnel si vous n’êtes pas sûr de savoir comment procéder.

La vidéo d'introduction est sous-titrée en français.

  1. Ouvrir votre téléphone endommagera ses joints étanches. Procurez-vous des bandes adhésives de remplacement avant de commencer ou évitez d'exposer votre téléphone aux liquides si vous le remontez sans remplacer les bandes adhésives.
    • Ouvrir votre téléphone endommagera ses joints étanches. Procurez-vous des bandes adhésives de remplacement avant de commencer ou évitez d'exposer votre téléphone aux liquides si vous le remontez sans remplacer les bandes adhésives.

    • Posez un iOpener chauffé sur un bord long du téléphone pendant environ deux minutes.

    • Vous aurez peut-être besoin de refaire chauffer et de réappliquer votre iOpener plusieurs fois jusqu'à ce que le téléphone soit suffisamment chaud. Respectez les instructions de l'iOpener pour éviter de le surchauffer.

    • Un sèche-cheveux, un pistolet à air chaud ou une plaque chauffante peuvent aussi faire l'affaire, veillez cependant à ne pas surchauffer le téléphone – l'écran OLED et la batterie à l'intérieur craignent la chaleur.

    I used a heat gun and heated it a little too much. The color of the rear glass is just a sticker on a clear cover. Due to this I tore the sticker off. Now the back cover is see through, which isn’t a bad thing but the repair was for a customer.

    Kevin Bishop - Réponse

    When using the iOpener, you may need more than 30 seconds, especially in compact or low wattage microwaves. Take this slowly, though, and be extremely careful, as it is easy to overheat your iOpener. Remember, you can always heat it up a tad more, but you cannot undo overheating it.

    Jacob Pratt - Réponse

    I used an adjustable heat gun and set it to 400 degrees (F). That was enough to seperate the glass without having to worry about exposure times of the heat. The front of the phone was just fine. Just be ready to use a bunch of picks to slide in between because they will be needed this way.

    Ryan Schumerth - Réponse

    I went from the bottom center up, using one ifixit tools, one suction cup and one pick.

    Pick just popped in with some minor pressure.

    Laid heat pack along base of phone 2 mins first and worked up slowly, rotating picks as I went. Had to heat iopener over several 30 second bursts

    Lauren Burt - Réponse

    This is useless because the phone does not recognize the new battery and will behave like on the old one

    Search for “battery count xda"

    Albert Einstein - Réponse

    That is an interesting discovery! Thanks for pointing it out—I’ll have to look into it.

    Even if this is true, replacing the battery should still give restore a significant amount of life, since the max voltage affects a minor amount of the battery’s capacity. If you charge a worn battery and a new battery to the same lower max voltage, the worn battery’s voltage will dip more under use and will be depleted faster.

  2. Quand la panneau arrière est chaud au toucher, posez une ventouse le plus près possible du bord chauffé du téléphone, tout en évitant le bord incurvé. La ventouse n'adhèrera pas correctement à la partie incurvée du verre. Si le panneau arrière du téléphone est fissuré, il se peut que la ventouse n'adhère pas. Essayez de le soulever avec du ruban adhésif épais ou de fixer la ventouse avec de la colle forte que vous laissez durcir avant de procéder.

    • Une autre option pour faire ramollir l'adhésif est de faire couler quelques gouttes d'alcool isopropylique dans l'espace créé en insérant le médiator.

    Because of the metal lip around the phone the picks were to thick to get under the glass. Couldn’t get the glue loose enough with the iOpener or the glass lifted high enough with the suction cup despite using a lot of heat and stength on the suction. Ended up having to use a thin piece of metal to get the first separaration. After that the picks are ok to use.

    This step is certainly giving me trouble. I don’t have enough hands to be able to both form the space and to insert the pick. In order to even form the space, I need to use the double-sided plastic scraper-thing.

    Turns out that three hands was the answer. I had my dad insert the pick while I pried open a gap, and it was smooth sailing from there.

    Apply heat with iOpener/blower or the isopropyl alcohol on the adhesive you want to remove.

    I did not and noticed I peeled off pieces of the paint coating from the cover glass together with the adhesive.

    The picture for Step 10 shows that no attempt was made to remove the residual adhesive from the phone side. I don’t think it is sufficient to only remove the old adhesive from the case back. For my disassembly, 50% stayed on the case back and 50% on the phone

    I diligently removed all the adhesive on the phone side. Tedious but necessary.

    As a final clean up step, when I rubbed a cotton swab dipped in alcohol near the flash and finger sensor, the black covering for the recharging coil dissolved before my eyes. There needs to be a warning in the instructions to avoid any alcohol or other solvent contacting the inductive charger coil. So far, it doesn’t appear this will interfere with the connector integrity at that dissolved spot,

    Unfortunately I can’t post the picture here.

See picture next step. Pry”, and “either” with “any”.

After this is it still waterproof?

Edgar Rodríguez García - Réponse

In theory, if you applied the replacement adhesive 100% correctly, it will retain its water resistant properties. However, I would never deliberately expose any device to water, as you can never be completely sure that all the seals are perfectly intact.

Jacob Pratt -

That is actually covered in the video. Did you actually watch it? If water resistant is important to you then what you would do is purchase new gasket material so that after you have opened up the phone and removed all the existing gasket you would apply the new gasket and then finish up and re-seal your phone. As to how water resistant it is after re-sealing the phone all depends on how careful you are and how exact your work is.

marketing major -

Sooooooooo why exactly did Samsung make it impossible to open the phone?

Dan Laemmerhirt - Réponse

Because screws are unsightly :P… and repairing your old phone makes you not want to buy a new phone.

Jacob Pratt -

scottrape - Réponse

How much time do I hit to open back panel? I almost hit 10min using hit gun but It didn't open at all.

Jay - Réponse

This was one of the most difficult repairs I have done, but it worked. First off I absolutely could not get anything except a tiny Flathead screwdriver wedged in to the glass to pry it up, which cracked the glass even more than it already was, but thankfully I was replacing the back glass as well. The battery was also glued in unbelievably well, and the battery ended up bending pretty bad when I pried it out, even with a lot of extra heat.

Overall a massive pain in the rear, but I got it all working properly now thanks to the video. I used a Wagner heat gun for this, I don’t think a hair dryer would be sufficient!

Eric Vardin - Réponse

I was a bit concerned cause I was using a 300w heat gun instead of the big one in the video, but patience paid off. One tip for anyone else is to make sure the battery is at the TOP of the cutout for it, my connector almost didn’t reach. Nothing broke, phone is on and running, only concern is that I didn’t get all the old glue off, so it might not be water resistant anymore.

Note: Much harder with a screen protector, ended up needing to remove mine and now it’s got dust under it. Luckily, that’s an easy fix, just annoying.

Brian Kurtz - Réponse

I wish that tip was in the installation guide as I had the same problem. I used the spudger to slide the battery up a little. It took more force then I would of thought to get the connector back on.

I accidentally jabbed the old battery rather hard, pierced it. And then that battery became amazingly very super hot. I’m up where winter is cold, and I put the battery out on my driveway lest it light something on fire. Was still hot as !&&* 20 minutes later. Now I understand why they say we should never put these things in the trash or a landfill cuz they could start a fire.

Tomás Rosales -

The guide was good but incomplete. It would have nice to have a little more info on removing the adhesive on the back panel and how to best reapply it. Since this was my own phone I was extra careful but found reapplying the back panel adhesive the hardest part. Not sure if the phone is pushing out in the top left corner or the adhesive is not doing its job. All parts and tools were purchased at iFixit.Com. I used a 800w heat gun and the iSlacks did not work. I cranked up the heat and opened case with my iPhone suction cups. Very cool to know that my apple tools can be used on an Samsung phone…lol…Wow that adhesive was strong. So what do you guys think, should I reheat new adhesive, get it soft then push down firm in that corner to get it to seat better???

Brian - Réponse

Just did a successful battery replacement. The back is A LOT more fragile than she makes it look. I anticipated and bought a replacement back. Otherwise the instructions are spot on.

brookman_69 - Réponse

Just finished:

I didn’t use a suction cup when taking the back off. I used a flat metal spudger and three plastic hotel room key cards (like credit cards without the bumps). I used a hair dryer and heated the phone for a minute or so. Then, when I was able to stick the spudger in right where the charging port is, I put the card in the spudgers place. After that, I was able to work my way to the left and then inserted another card when I got to the corner. As I went through, I had a pick (shaped a bit less pointy than the tip of a dart) which I would use to “cut” through the adhesive. This worked very well.

I heated it up a bit with the hair dryer and used the spudger and card and got it out without any damage.

The hardest part of this BY FAR is attaching the new battery. The ribbon cable that is attached to the new battery is slightly too short. Therefore, you need to smush the top of the new battery and its really a pain to get it in. Make sure to attach the new battery before putting it into its spot.

My employer has about a dozen sales guys in the field, each with an S7. My supervisor agreed to sell me their trade-ins at carrier price. With this guide, I was successful in replacing the battery and can expect about a $150 profit. Thanks iFixit!!!

An update:

The replacement battery provided to me by ifixit didn’t work. Returned it and tried another and it also didn’t work. Took it to an authorized repair shop (ubreakifix) and it worked. I would suggest that people just go to the repair shop. Saving the $20 just isn’t worth the hassle. Make sure you keep your original battery no matter what.

ploppalopp - Réponse

The battery I purchased from ifixit is worse than my original battery! My old battery at least shut off at 1%, this battery shuts off anywhere from 19%-49% !!!!!

These instructions were pretty thorough. I used a microwaveable rice bag as a warming source. Tried a guitar pick, but too soft and flexible to start the process. Used a carpet knife instead to start, cracked the back (ordered a new one). Then used the pick to slide along edges. To get the battery out I pried and used heat and alcohol. Once I got it lifted enough, I inserted the guitar pick and slid it around under the battery. I’m glad I bought 2 batteries over the Internet from China because 1 was too wide to fit into the phone’s battery frame. The other fit. I would recommend plugging in the connector 1st as I could not quite get it lined up to connect otherwise. Also, do not screw down the battery cover before aligning antenna piece as it has clips that need to align 1st.

Arthur Shi -

Despicable of Samsung…

Jesse - Réponse

How long does it take to heat up before you can actually remove the back panel? I spent 15 minutes heating up the back with a blow dryer and had absolutely NO luck, even after the back cover was hot to the touch. It seems from watching videos that people had success with getting the back to budge open after just a couple of minutes with a blow dryer. The phone itself is getting hot, I’m applying the heat to the edges as recommended and it just seems nearly impossible. To top it off the back cover cracked when I did try to pry something underneath the cover. Any tips or suggestions would be greatly appreciated.

Eugene Smith - Réponse

Hi Eugene,

The hardest part of this repair is the initial opening procedure, and the adhesive on these back covers can be very stubborn! I would suggest trying to focus the heat towards one of the long edges of the back. Once the edge is hot to the touch, apply the suction cup close to the center of the edge and pull with strong, steady force. You can try to loosen the adhesive by pulling on the suction cup repeatedly. Once you get an opening pick into the seam, proceed to heat the rest of the perimeter as you work. Good luck!

Arthur Shi -

Nice work, good guide. A few more notes:

1) If using a a case, check to see if the back cover is cracked before ordering the battery. If so, it may be necessary to order a new back cover.

2) It doesn’t require all that much heat to get the cover off. I used a paring knife to start it, rather than the flimsy pick .

3) Taking off the speaker assembly is not strictly necessary to get the battery out, but I did so as not to risk damage to its board and enable prying out the battery with less difficulty. Then I did not glue the battery in at all when putting it back.

4) Take care to reconnect the battery, and temporarily power it up before putting the rest back together. The connector is tiny, and not easy to seat.

5) If you use protective case and want the adhesive to come off easier if you ever have to replace the battery again, wear gloves, tack around the adhesive strip with the gloves to make it a bit less sticky before putting the new adhesive on, and don’t use any heat during the reinstall.

Question: What is that black covering under the battery in the battery compartment area? I scratched it up somewhat when removing the adhesive from the battery (huge pain) and want to know if this will be a problem. Is there something I can do to repair the black covering if I need to?

rayzor12 - Réponse

Hey rayzor12!

The black covering is one of the layers that protects the display panel. It also helps dissipate heat from the phone through the display. If your display works and the surface facing the battery is relatively smooth, you should be fine.

Arthur Shi -

How important is it to glue/adhere the battery again when replacing it? I swapped out the battery and closed it up before considering that I should have used adhesives. Will this be a problem and should I go back in and open the phone again to secure the battery?

rayzor12 - Réponse

If the battery is completely loose in the phone, I would strongly suggest opening it up and affixing it in place. You do not want the battery to move around during daily use, as the edges will wear down and cause potential fire hazards.
