Asus ZenFone 2 Battery Repair
Asus ZenFone 2 Battery Repair Guide
Power down your Asus ZenFone 2.
Step 2 (Asus ZenFone 2 Rear Battery Cover)
Use the plastic triangle opening tool, or your fingernails, to work around the ZenFone 2 rear cover and release the plastic clips securing it in place.
Step 3 (Asus ZenFone 2 Exterior Midframe)
Remove the following 14 Phillips screws.
Easily separate the exterior midframe from the Asus phone.
Step 4 (Asus ZenFone 2 Battery, Loudspeaker, and Dual-SIM and microSD Card Slots)
Disconnect the ZenFone 2 battery from the motherboard.
Use the spudger to pry up the loudspeaker.
Detach the interconnect cable from the motherboard.
Remove the Kapton tape, and detach the interconnect cable from the daughterboard.
Locate the peel-to-remove adhesive tab at the top of the battery. Grab the tab and try to keep the adhesive strip flat and wide. Slowly pull the strip up and away from the Asus ZenFone 2. The strip will stretch to many times the length of the battery- keep pulling until it comes out from between the battery and the midframe.
And just like that, out comes the 3000 milliampere-hour (mAh) Asus ZenFone 2 battery.
The ZenFone 2 battery is strongly adhered to a protective metal cover, but with a little spudgering it is readily freed.
* To reassemble your device, follow the steps in reverse order.
