I had battery drain after the update but it appears to be network/signal related. Always get 4G in my home but now only get H. Turning off WiFi left my phone with no mobile signal but seems to fixed with a couple of reboots. Signal is definitely no where as good.
Noticed the same last after the update. I hate it when there's no stable signal. I'm gonna do a factory reset just in case. Hope these things will be fixed soon enough. Don't want my first pixel experience to be ruined by these. I had such high hopes.
Same issue with me. Never had problems with signal until yesterday. Thought it was o2 problem but clearly not. Literally no signal at home and when driving back from work got disconnected every 2 miles.
When I first got the phone I had an issue like that. Try turning the phone off (not reboot) and then powering on after a minute or so. When I did that last build it built cache or did something different and the issue went away.
Since the December update, I've got massive battery drain. The latest session for accubattery has only 11% deep sleep while the screen is off. 35% battery usage over 6 hours with 46m SOT. Has the adaptive battery reset? Any ideas please?
