Introdução
Use this guide to replace a worn-out or dead battery in your iPhone 14 Pro Max.
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 A2894 (international) model. If you're fixing a different iPhone 14 Pro Max 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, take appropriate precautions.
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 Repair Assistant.
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.

Power off your iPhone before beginning disassembly.

Support your iPhone on something sturdy such as a hardcover book so it rests hands-free and parallel to the ground; this makes it easier to work with in the following steps.

Use a pair of blunt-nosed tweezers to peel down the two battery adhesive pull-tabs along the bottom edge of the battery.

Grab the first pull-tab with your fingers or wrap it around a spudger and slowly pull it away from the battery, toward the bottom of the iPhone.

Don't press down on the battery. Hold the iPhone firmly by its sides.

Keep the strip flat and unwrinkled. Try to pull evenly on the whole strip, rather than pulling mainly in the middle or on one side.

If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling—but do not pry under the battery.

Grab the second pull-tab with your fingers or the center of a spudger and pull it away from the battery, toward the bottom of the iPhone.

Use an opening pick or the flat end of a spudger to gently lift the battery.

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 calibrate it using Apple's Repair Assistant, 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, calibrate your newly installed battery after completing this guide.

Very good.
Perfict structure for changing the battery
Once I have followed all the steps and have removed the battery, how do I reconstruct the iPhone afterwards? Do I just do the steps again, but in reverse order? Help would be much appreciated.
Hi Louis,
to reassemble your device, you need to follow these instructions in reverse order. During reassembly apply new adhesive where necessary after cleaning the relevant areas e.g. with isopropyl alcohol (>90%).
Thanks for the guide! I wonder: How to make it so that Battery Health info appears after replacing the battery with another one (also OEM)?
