Introduction
Use this guide to replace a worn-out or dead battery in your Huawei Honor 8.
If your battery is swollen, take appropriate precautions. For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.
You’ll need replacement adhesive to reattach components when reassembling the device.

If possible, turn on your phone and test your repair before installing new adhesive and resealing the phone.
Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the phone at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.
To reassemble your device, follow these instructions in reverse order.
For optimal performance, calibrate your newly installed battery: Charge it to 100%, and keep charging it for at least two more hours. Then, use it until it shuts off due to low battery. Finally, charge it uninterrupted to 100%
Take your e-waste to an R2 or e-Stewards certified recycler.

If you use isopropyl alcohol to dissolve the adhesive and remove the battery make sure it doesn’t go towards the screen (as the phone is likely going to be facing down) and that it dries completely before closing up the phone again.
I made the mistake of leaving the phone - although still opened - face down overnight and the alcohol seems to have gotten into the screen, causing bubbles and discoloring on the screen.
Thank you very much for this guide, great help! I also changed the usb port and had to watch the guide for that also :) Took some more time for a firt timer hehe, Also I did not have the pre cut adhesive, only 3 mm. I will probably find one and order it.
Very good guide, thanks a lot! I didn’t have the iOpener, so, I used very hot water in a ziplock bag and it worked great.
Very good guide, but actually, I didn’t even need to remove the circuit board. With enough warmth from the iOpener on the display side and cautiously working with all the picks, I was able to remove the battery right after removing the middle frame.
