Use this guide to remove the main flex cable assembly including vibration motor and microphone, the loudspeaker and the side button flex cable including the charging port.
Opening the Sony Xperia Z4 will damage the waterproof seals on the device. If you do not replace the adhesive seals, your phone will function normally but will lose its water protection.
Due to the phone’s design, you must remove the lithium-ion battery in order to access the flex cable assemblies. Do not re-use a bent or damaged battery, as doing so is a potential safety hazard.
Before disassembling your phone, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.
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.
