Upgrade went fine, but I am experience severe power management issues on my C2 (HW ver 2.0.0.59) since then:
PROBLEM: Some hours (today about 3hrs, but also some 5 or 8 hrs in the days after the upgrade) after disconnecting the USB-C power supply the phone suddenly shuts down and can only be rebooted properly after a power is connected.
Today this happend some tens of minutes after I observed the battery indicator in the top of the screen indicating a battery level of the order of 90%, so it drained very quick, very suddenly.
After that I had no access to a power supply (on a 5 hour hike through a forest) but I tried to reboot it a couple of times to gather some phenomenology:
Common behaviour: the phone shut down every time after typing the device pin twice and the sim pin.
- time the first indicated power level was 8%, which dropped to 5% suddenly and the device told me “goodby”.
- second time after waiting (hiking, without connection to ANY power supply) a couple of minutes, first display of the power level was of order 38% (?!?) but after the 3 PIN-entries the device mentioned an empty battery and told “goodby” again.
- After some 20-30 minutes the battery indicator claimed 50% initially, which changed to 45% after the PINs but some seconds later the “goodby” shut down occurred again.
So it feels as if the calibration of the battery level sensor is broken after the upgrade.
Or some process suddenly drains a lot of power (for no good reason since I have not exeprienced this issue before this release) and no power management process steps in to kill this.
Please help!
