@MrT10001 thanks

The raspi(s) would receive the OTA updates. I already looked into Mender SWUpdate, RAUC and they all seam promising. I would actually just like to know out of curiosity how UBports handles OTA updates.

I would consider it to be quite stable and usable on Oneplus 5t.

@aimar said in Batter life since last OTA: Could this "out of calibration" issue be the reason to the inexplicable draining of the battery? Yes. What does "out of calibration" means? That it is not calibrated. (Sorry for my English) How/When/Why could it happen? It's complex, I think it's best to look at ddg.gg, I'm sure someone has explained it better than me. Also, not everyone agrees on how to charge a battery. Does it means that the battery is dying? No

@delijati don't give up!
