Replace iPhone battery

1. Apple Service You can get your iPhone’s battery replaced by Apple or an Apple Authorized Service Provider. The cost will depend on your iPhone model and if the issue is covered by warranty, AppleCare+, or consumer law. Note that if your iPhone has any damage that impairs the replacement of the battery, such as a cracked screen, that issue will need to be resolved prior to the battery replacement.

2. Do It Yourself: If you’re comfortable doing the replacement yourself, there are many guides available online that provide step-by-step instructions. Here’s a general process:
Power off your iPhone and remove the two pentalene screws at the bottom edge.
Use a suction cup and a sludger to pry the display from the rear case.
Disconnect the battery, the two lower display, and the front panel sensor assembly connectors from the logic board and remove the display²[5].
Remove the barometric vent and the tactic engine from the rear case.
Peel and pull the adhesive strips from the battery, and remove the battery.
Install the new battery and reassemble the phone in reverse order.

Please note that opening up your iPhone can void its warranty and potentially cause damage if not done correctly. It is best to get it done by a professional if you do not feel comfortable doing it yourself.

3. **Third-Party Repair Shops**: There are many third-party repair shops that can replace your iPhone battery for you²[5]. Just make sure to choose a reputable shop to avoid any potential issues²[5].

Remember, safety comes first. If your battery is swollen, take appropriate precautions³[6]⁴[7]⁵[8]. And after the repair, your iPhone may display a warning about the “genuineness” of the battery, even when using original Apple parts³[6]⁴[7]⁵[8]. Happy fixing! 😊
