Retested the idle current with 4.5.0.18, and it remains as before ~0.8%/hr
Flightmode, gps off, android stopped. I turned battery saver on this time. I also restarted the phone in flightmode as suggested by @jojomen
edit: tried disabling NFC too - no effect.
edit: Ran with Wifi,BT,Cellular on for 12hrs, 80->71% = 0.75%/hr i.e the same drain flightmode on or off.
I have Skype and VKPortalog running in Android, and I don’t (informally) perceive much excess drain.
BTW, just ran a long flightmode test of the Android 12 X10iii. WhatsApp and Skype are running.
4d18h 60%->39% = 0.2%/hr
