Thank you for your asking. Kindly try some stay-at-home troubleshooting tips below:
1. Is there any zone heating up while using/idling?
2. How long has the battery been used?
3. Enter "Safe Mode" and leave a 100%-charged phone in sleep(idle) mode in a night, then provide me the screenshot of
②Setting>Battery>3 dots on the top"Show app usage"
# How to enter and exit "Safe Mode"https://www.asus.com/support/FAQ/1005163/
If the battery works well in "Safe Mode", please check on any disturbance from the installed 3rd party Apps.
4. Also, 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.
