Introduction
iPhone batteries are rated to hold 80% of their capacity for up to 500 charge cycles, which lasts roughly 18-24 months for most users. After that, your iPhone may need to be charged far more frequently, and iOS may warn you that performance is affected (in other words, your phone will run slower). Use this guide to replace your battery and restore your iPhone to like-new performance.
If your battery is swollen, take appropriate precautions.
Note: After the repair, your iPhone may display a warning about the “genuineness” of the battery, even when using original Apple parts. If your iPhone functions normally, you can safely ignore the warning.
For optimal performance, after completing this guide, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least two more hours. Then use your iPhone until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.
Video Overview
-
-
Power off your iPhone before beginning disassembly.
-
Remove the two 6.9 mm-long pentalobe screws at the bottom edge of the iPhone.
-
Opening the iPhone's display will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.
-
-
-
Use a hairdryer or heat gun or prepare an iOpener and apply it to the lower edge of the iPhone for about a minute in order to soften up the adhesive underneath.
-
-
-
Remove four Y000 screws securing the logic board cover bracket, of the following lengths:
-
Two 1.1 mm screws
-
One 1.5 mm screw
-
One 3.7 mm screw
-
-
-
Remove the three Y000 screws securing the display connector bracket:
-
Two 1.5 mm screws
-
One 1.1 mm screw
I am replacing the screen for the 2nd time - the first repair was done by someone else, and the first 2 screws are 1.5mm and the last screw is 1.1mm… If I put the screw back in am I risking Long Screw Damage?
Thanks for all your comments! I'll amend this step.

-
Carefully lift the cable until the adhesive separates.
-
-
-
Remove the five 1.4 mm tri-point Y000 screws securing the bracket below the Taptic Engine and main speaker.
-
-
-
Remove the three screws securing the speaker:
-
One 2.7 mm Phillips screw
-
One 2.9 mm standoff screw
-
One 3.1 mm standoff screw
-
-
-
Use a spudger to disconnect the Taptic Engine flex cable by prying it straight up from its socket.
-
-
-
Each piece of adhesive has a black pull-tab at the end, which is lightly adhered to the side edge of the battery.
-
-
-
To increase your odds of success:
-
Don't press down on the battery. Hold the iPhone firmly by its sides.
-
Keep the strips flat and unwrinkled as you pull.
-
Pull very slowly, giving the strip time to stretch and separate. It takes around 15-30 seconds of stretching to remove each strip.
-
Pull at a low angle so the strip doesn't snag along the bottom edge of the battery.
-
If a strip does break off underneath the battery and cannot be retrieved, move on to the other strips and then continue with the additional steps below.
-
-
-
If any of the adhesive strips broke off and the battery remains stuck to the rear case, prepare an iOpener or use a hair dryer to heat the rear case directly behind the battery.
-
Flip the iPhone back over and thread a strong piece of string (such as dental floss or a length of thin guitar string) underneath the battery.
-
Pull the string from side to side in a sawing motion to separate the adhesive. This can take some time since the adhesive is slow to deform, but with patience it will come free. Do not deform or damage the battery.
-
Start from the top or bottom edge of the battery, and pull toward the middle. Don't pull the string through the middle third of the battery, or you may damage the ribbon cables or the wireless charging coil directly underneath.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.
To reassemble your device, follow the above steps in reverse order.

Does anyone have an answer to my issue I’m currently facing? Bought a refurbished iPhone XS Max online and looks like the seller has replaced the battery, however the phone is experiencing technical difficulties as it keeps switching off and restarting every 1 minute or so. Could this be because they didn’t use a genuine apple battery as a replacement or they just didn’t fit the battery correctly when replacing it? I really appreciate if anyone could help, would save me a tonne of money that apple will probably charge me if I go to them for help.
They probably used a “amazon” battery the best way would be to replace it your self.
Ein Hinweis darauf, wie man das Batteriemanagement-Board vom alten Akku auf den neuen Akku überträgt wäre als Add-on sicher hilfreich. Der Aufwand ist überschaubar (Werkzeug wird benötigt), und dann erscheint auch die Meldung mit der Batterienachricht nicht mehr.
