Introduction

Use this guide to remove or replace a worn-out battery in a Sony Xperia Z5.

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.

If you do not replace the adhesive seals when reassembling, your device will function normally, but will most likely lose its water-protection.

You’ll need replacement adhesive to reattach components when reassembling the device.

Insert an opening pick into the gap to further separate the rear glass from the phone assembly.
The adhesive of the Xperia Z5 is fairly weak and it is possible to remove the rear glass without the use of an opening pick. In case you‘re having trouble you can have a peek at the opening procedure of the Xperia Z4.

Step 3

Carefully lift and remove the rear glass.

After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.

The adhesive strips underneath the battery can rip very easily. Make sure you pull at the tabs in a slow and steady motion and in a flat angle. To prevent the adhesive strip from ripping, it's helpful to twist it around the tweezers.

In case one of the adhesive strips rips and it‘s not possible to pull it out completely, you can use isopropyl alcohol or an heated iOpener to loosen the adhesive. After the adhesive is soft enough use a prying tool such as an opening pick or a plastic card to pry out the battery.

Conclusion

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.

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%

To reassemble your device, follow these instructions in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.
