Use this guide to replace a worn-out or dead battery in your Huawei P8 Lite (2017).

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.

  1. Heat an iOpener and apply it to the rear glass for two minutes.
    • Heat an iOpener and apply it to the rear glass for two minutes.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the P8 Lite—the display and internal battery are both susceptible to heat damage.

  2. Apply a suction cup to the rear glass, as close to the right edge as possible. If the phone's rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.

    • Pull up on the suction up with strong, steady force to create a gap.

    • Depending on the age of your device, this may be difficult. If you have trouble, apply more heat to further soften the adhesive and try again.

    • Before installing a new battery, remove any remaining adhesive from the phone, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

    • 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 device at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.

Sonuç

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. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device 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.

Hi there, thank you for this guide. I was just wondering what adhesive/ adhesive tape to use when re assembling the phone as I’m not familiar with what is suitable? Also, is there a particular brand of isopropyl alcohol to get? All the best, Ruari.

Hi Ruari, take a look at our store. You will find a range of different adhesives there. For the attachment of your battery I recommend these stretch battery adhesive. For the reassembly you can use this tape or another thin double-sided tape. For removing any remaining adhesive you can use this adhesive remover or remove large chunks of adhesives with your fingers, spudger, plastic opening tool, or tweezers. Good luck and have fun with your repair!
