Battery problem?

[myusril785]

So I recently just bought a new battery because my old battery is draining so fast. After I replace it just working fine and good. But then I notice the battery drain so fast from 100% to about 80% and when under 40% it drain like about 2-10 min per 1% under 40%

Hi myusril785
Thank you for asking. Did you repair your battery in ASUS repair center. If you did, please contact with your local repair center. If you did not, please try the troubleshooting tips below
1. Enter "Safe Mode" and leave a 80%-100% phone in sleep(idle) mode in a night, and exit "Safe Mode" then try the same process the next night

If the battery works well in "Safe Mode", please check on any disturbance from the installed 3rd party Apps.
2. If the issue remain the same in "Safe Mode", please try "the Factory Reset"
Settings>System>Reset options>Factory data reset
Please note that once the Factory Reset is completed, all data, apps, settings and personal information will be deleted.
