Odd Battery Behaviour

Star II

Model Name: ASUS_AI2022 (Zenfone 9)
Firmware Version: WW_33.0804.2060.189
Rooted: NO


Recently my phone's battery percentage level has started acting erratically - or rather - squarely .

Attached are screenshots from the phone's Battery Usage and battery seems to charge itself instantaneously before immediately jumping down to a more "normal level".

Has anyone else seen this behaviour? 

Something for sure seems wrong to me.


Star III

other's Drain battery 32 %


My issue isn't so much a battery drain issue, rather that the battery appears to self charge and mis-report it's actual percentage.

Not applicable

this is one of the (many) well known issues with the latest .189 update. there is no fix available, as of right now. a future software update may fix this, but i wouldn't hold my breath.

asus does not care about their customers, they have communicated that very clearly.


Hey @gurpz1 and @leandro31187,
Can you please share the battery log?
Please follow the below steps to enable the built-in log tool (Bug reporter).
1.  Open “Calculator APP”
2.  Enter “.19595+=”
3.  Select the Log type according to the type of issue you want to capture. “General cases” will work for most issues.
4.  After your selection the log tool will exit so you can duplicate the issue or wait for it to happen. Try to use the screen recorder to show your issue when possible. If you can't screen record your issue, then please take a screenshot right after the issue has occurred (as a timestamp) so we know where to look in the log.
5.  Navigate back to the log tool via calculator and Tap "FINISH AND SHARE".
6. It takes several minutes for the log to generate. You can exit and do other stuff in the meantime. A silent notification will tell you once the process is done. Tap the notification and then the share button to upload the file to Google Drive and share the link with a moderator. Just make sure to change the permission first so that everyone with the link has permission to view it.
Note: When you're no longer planning on logging your device, enter “.09595+=” in the calculator and the log tool will stop as well as deleting all stored log files. Make sure to share via calculator. The files found in internal storage -> asus_log are not the correct files (they are only 1.2kb)
