(HW/SW Issue, experience) ASUS Smartphone for Snapdragon Insiders (Snapdragon 888) stuck at 81% battery
Hi, I have an ASUS Smartphone for Snapdragon Insiders (Snapdragon 888) with a strange battery issue.
The phone is stuck showing 81% battery. The percentage does not change at all, even after using the phone. It also shows the charging indicator constantly.
The issue was already present before updating the phone. The device was on a very old firmware (Android 11, December 2021 security patch), and I updated it through several OTA updates. The current firmware is 18.1055.2307.269, but the problem remains.
I already performed a factory reset, but it did not fix it.
Interesting behavior:
When the phone is powered off and I connect the charger, it shows 81% and then immediately jumps to 100%.
After booting into Android, it goes back to 81% and stays there.
The battery does not seem to drain normally because the percentage is frozen.
Could this be a battery calibration issue, a battery gauge / fuel gauge problem, or a failing battery controller?
Has anyone experienced something similar on the Smartphone for Snapdragon Insiders?
