Please tell us some basic information before asking for help:
Model Name: ROG PHONE 3
Firmware Version:
Rooted or not: NOT
Frequency of Occurrence: Always (Since the aforementioned shutdown)
APP Name & APP Version (If your issue relates to the app):
After the initial shut down my phone keeps getting hotter even with no apps running. It stays at 40~43C° and hotter if I open apps.The battery is draining like water too. Restarting or shutting down the phone for awhile does not help. Delete some of my games or useless apps does not help too.

Have you tried a factory reset?

[indra13julius]

Not yet, because I have too many important chat to delete... And it's really a hassle.... I have this phone for just four months...and I have to factory reset it?

Hello there , i would recommend you to turn your phone into safe mode and see if it's still persists , I doubt there is some 3rd party app creating problem .
How to Enter Safe Mode?
Apply to：Phone, Pad
When power is off:
1. Long press power key to boot.
2. When ASUS logo appears, press and hold volume down key till home screen appears
3. " Safe Mode " reminder appears on the lower-left of home screen
To exit it just simply reboot again .
And please update if problem is also happening in safe mode .
Try to take in safe mode for atleast 2 hours or wish .
Thank you .
