iPhone 6 & 6S Flickering after Battery Replacement *SOLVED*

I have been mainly refurbishing iPhone 6 & 6s batteries over the course of the last 2 days & have came across some interesting stuff dealing with the screens flickering after replacing aftermarket, even OEM parts.

What I have come to find is that if you are wanting to replace just the battery without removing any of the LCD/Home Button/Front Camera,etc. flex cables DO NOT just unplug the battery with the phone still ON. Unplugging the battery with the flex cables still attached (without even removing the bracket holding the flex cables down) while the phone is ON, then reconnecting a new battery will cause the screen to flicker most of the time, even if its an OEM screen… Id say its about a 80% rate the screen will flicker if using this technique by not powering down the device with the power button and sliding power off.

If you want to replace the battery without removing the flex cables, POWER DOWN the device by holding the power button and sliding power off. Wait around 10 seconds (or the amount of time it takes you to unscrew the bottom screws & battery screws). 100% of the time I use this technique I have had 0 screens flicker.

I have tested both techniques with over 50+ phones over the past 2 days. All using the same replacement battery from the same vendor.

It does not matter if the screen is OEM or aftermarket. You will get a flicker MOST likely if you use the first technique I explained. Some iPhones did have an exception where the screen did not flicker when I disconnected the battery with the phone still ON.

I do not know the ins & outs as to why this is the case but I have found of this will cause your screen to flicker in the 6 & 6s.

I have not tried any other models yet as I am only refurbing i6 or i6s batteries currently.

Just thought Id throw this information out there to save the anxiety for people if this ever happens to them.

From what Ive read the flickering should go away after hours of leaving the devices on but I am unable to test that part since I pass the phones on once refurbished.

So if you want to avoid your screens flickering. POWER THE DEVICE OFF USING THE POWER BUTTON & SLIDE POWER OFF & Be patient.

I replaced my iPhone 6 battery and after the process my phone starts automatically on/off within a minute.

It repeats continuously. What to do with that?

What about if the lcd is unresponsive and I had no choice but to disconnect the battery for screen and battery replacement..? I had an iPhone 6 come in which had vertical lines so I couldn’t shut the phone down properly.. after screen replacement the screen seemed fine. The customer them asked to replace the battery and I did shut it down properly and swap the battery out but then we discovered the flickering screen. It may have flickered before the battery replacement and we just didn’t notice since it was only of for a minute.

I’ve let the phone sit over night on at my shop I hope when I go back the flickering is gone

Thanks for sharing, encountered the same. Very interesting

I powered on my phone after battery replacement and was having grey lines, touch wasn't responsive so i couldn't shut it down by sliding, so I disconnected the battery while display was connected. Is there any fix or does this just sometimes damage the display and cause flickering?

When a battery is being replaced, if the adhesive battery tape snaps off whilst it is being pulled out, the iTech may use alcohol to release the tape. If the screen is still connected, the alcohol may seep under the screen connectors. Although most of the alcohol will evaporate, the alcohol under the screen connectors will take longer to disappear. This will cause the screen to flicker and may even damage the circuit board as the alcohol is causing mini shorts.

Remove the screen connectors to ensure there is no alcohol underneath them. Additionally when using alcohol to dislodge the battery adhesive tape, dip the card / tool in to the alcohol as apposed to squirting alcohol in to the phone or under the battery.

This would explain why switching the phone on and off several times may cause the issue to go away as the alcohol evaporates.

@mrbitcoin great information but it will get lost since it is not a question/answer. Post it on here https://www.ifixit.com/Story/new so it will remain for others to read.
