Battery indecator drops to zero within seconds of unplugging #20

Notsonoble commented 2 years ago

As soon as I unplug a charging cable from my cutiepi, the battery indicator drops from 80 to 0 in increments of 5%, it obviously has some capacity, because it doesn't shutdown. A fresh install of the most recent image still does this.

I see a variation on this - the level drops off very quickly, but often then seems to creep back up after a while.

Determining the charge level of LiIon batteries is hard....

Further to this - I was away for a few days, so my Cutiepi was unused: It was fuly charged when I left it, but after 4 days switched off, the battery was showing 10%. That does not seem reasonable for a LiIon battery - is something wrong? Is the tablet "fully off" when it is off? Or is it actually in some sort of standby low power state and still using the battery?

Fixed the indicator in latest image, I'm closing this one. https://github.com/cutiepi-io/pi-gen_stage4.5-cutiepi/releases/tag/2022-04-01
