Use this guide to replace a worn-out or dead battery in your iPhone 14.

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).

This guide was created using the ***A2882*** (international) model. If you're fixing a different iPhone 14 model, there may be some visual discrepancies, but the procedure should be the same.

***For your safety, discharge the battery below 25% before disassembling your device.*** This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, [[What to do with a swollen battery|take appropriate precautions|new_window=true]].

***Note***: On iOS 17.6 and earlier, your iPhone may display a warning about the “genuineness” of the battery after the repair, even when using original Apple parts. If your iPhone functions normally, you can safely ignore the warning. On iOS 18 and newer, authenticate your new battery using Apple's [link|https://support.apple.com/en-us/120579|Repair Assistant|new_window=true].

You’ll need replacement adhesive to reattach the battery and the screen when reassembling the device. Your device will function normally, but will most likely lose its IP (Ingress Protection) rating.

If possible, turn on your device and test your repair before installing new adhesive and resealing.

***To reassemble your device, follow these instructions in reverse order.***  During reassembly apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

After your repair, depending on the replacement part, you may be able to [link|https://support.apple.com/en-us/120579|calibrate it using Apple's Repair Assistant|new_window=true], available as of iOS 18. Update your device, navigate to Settings ***→*** General ***→***About ***→*** Parts & Service History, tap Restart & Finish Repair, and follow the onscreen prompts.

For optimal performance, [[Battery Calibration|calibrate your newly installed battery|new_window=true]] after completing this guide.

Take your e-waste to an [[E-Waste|R2 or e-Stewards certified recycler|new_window=true]].
