uConsole battery calibration issue

Hi,
I just got Uconsole cm4 and installed kali linux, the problem is when the battery percentage around 75% it shuts down. I have tried to calibrate it with

“ * echo 1 | sudo tee /sys/class/power_supply/axp20x-battery/calibrate”
Charged battery to 100%
drain it until shuts down

but that didn’t work. Any help would be appreciated.

Are you sure you tried everything before you posted a separate topic that sounds like a couple others?

  • You may need to calibrate more than once until you get the desired figures. Or go for a couple more power cycles before the situation goes away.
  • Are you sure your batteries aren’t the sketchy sort? Have you tested the batteries’ properties thoroughly before inserting them?
  • You may consider showing the battery statistics reported by the device.

Hi, Thank you for your response, I found the problem. When I check the batteries, one of the slots wasn’t working. There was no connection between negative terminals because of loose connection to the main board
