Difficulty: Moderate
Time: 20–40 min Our repairs: 90-day warranty
If your iPhone dies by mid-afternoon or shows degraded battery health, a fresh battery brings it back to life. This guide walks through opening the phone, safely removing the old lithium cell with the pull-tabs, and fitting a new high-grade battery — with the safety steps that matter around a lithium cell.
Before you start:
- Never puncture or bend a lithium battery — it can catch fire.
- Disconnect the battery connector before removing the cell.
- Don't reuse a swollen battery; recycle it properly.

Choosing your part: Use a Genuine OEM or high-grade battery with the correct capacity — cheap cells lose capacity fast and can swell. Avoid no-name batteries.
Step-by-step

- 2 Disconnect the batteryRemove the connector bracket and unplug the battery before touching anything else.
- 3 Release the adhesiveUse the pull-tabs if present (pull slowly and evenly), or apply gentle heat and pry the old cell out with a plastic tool — never a metal one against the cell.
- 4 Fit the new batterySeat the new battery, route and reconnect its flex, and apply fresh adhesive strips to hold it.
- 5 Reconnect & testReconnect the display, power on, and confirm the battery charges and reads a sane health figure before sealing.
