Do a battery calibration by following the instructions below
Discharge your phone fully until it turns itself off.
Turn it on again and let it turn itself off.
Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
Unplug your charger.
Turn your phone on.
I think this will solve the issue.

hey i tried to do that multiple times but once it turns off i cant get it to turn on to do the STEP:2 . i plug it in to turn on and try to drain but it directly goes from 40-50% to zero to off

Download the previous stable build and install it. It will wipe all your data so do take a backup. And after that never ever install any update from asus. Thank you.
