Please tell us some basic information before asking for help:

  1. Model Name: ZS620KL
  2. Firmware Version: .87
  3. Rooted or not: Non-rooted
  4. Frequency of Occurrence: Constantly
  5. APP Name & APP Version (If your issue relates to the app): System

In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.


  1. I felt battery percentage holds on a number for a while and then runs out quick suddenly after moderate or heavy use, instead real-time monitoring the charge as expected.
  2. It happens too when 100% charged, then - when unplugged - it drains the first 10% very quick.
  3. Now, I needed to restart the device with 5%, it just turned off, didn't try to turn on again and just shown the empty battery.

Could you take a look on the sensor settings?

It seems this is a recurrent bug of the Android 10 builds on 5Z.

Already tried:

  • Wipe data/Factory reset (nothing changed)
  • Other Android 10 builds (nothing changed)
  • Battery calibration (nothing changed)
  • Downgrade to 9 (but I can't stay there because of low wi-fi signal bug and security patches)
