Installation guide - Replacing an iPhone battery
General guidance for this part type - always follow your device manual- Pentalobe and small Phillips / tri-point precision screwdrivers
- Suction cup and thin plastic opening picks
- Hair dryer or heat pad
- Plastic spudger and tweezers
- Isopropyl alcohol (90% or stronger)
- New battery adhesive strips and a new screen seal
- On iPhone XS and later, a non-Apple battery shows an "Unknown Part" or battery service notice in Settings. The battery still works normally; the notice is Apple's parts message.
- Lay screws out on paper in the order they came out. Phone and laptop screws differ in length, and a long screw in the wrong hole can damage the board underneath.
- If the old battery is swollen, do not press, bend or puncture it. Tape over its contacts and take it to a battery recycling point; never put it in household trash.
- 1Prepare the phone. Run the battery down below about 25% (a full lithium cell is far more dangerous if punctured), switch the phone off, take out the SIM tray and remove the two screws beside the charging port.
- 2Open from the screen side. Warm the bottom edge until it is hot to the touch, lift the glass with a suction cup and slide a pick into the gap. Run the pick round the bottom and sides only a few millimeters deep, so it never cuts the display cables, then open the screen like a book. Do not bend it past 90 degrees.
- 3Disconnect the battery first. Unscrew the small bracket over the battery connector on the logic board and pop the connector up with the plastic spudger before you touch any display cable. Then unplug the display cables and set the screen aside.
- 4Remove the old battery. Pull the stretch release adhesive tabs out slowly and flat, at a low angle, one at a time. If a tab snaps, drip isopropyl alcohol under the battery, wait a minute for the glue to soften and lift it with a plastic card. Never pry with metal or bend the battery.
- 5Fit, test, then seal. Stick the new battery down with fresh adhesive, reconnect the display cables and the battery connector last, and power on. Check touch, Face ID or Touch ID and charging before refitting the brackets and sealing the screen with a new seal. Charge to 100% before regular use.
This is general guidance for the part type, not a model-specific procedure. If the part does not fit without force, stop and recheck compatibility.
