Hi guys, after the various flashes of the firmware I think I have lost the right battery calibration, immediately after charging the device I never get an icon that shows 100% as well as when it is discharged it does not show the plug icon, and then turn off suddenly, I'm doing some discharge and charge cycles, but it doesn't seem to solve the problem. Is there any way to do a precise calibration?

On the web I found this post but it doesn't seem to fit our device
