Kind of old thread, hopefully someone has an idea. I turn off WiFi each night (at least 8 hours WiFi off, airplane on). I charged to 100% last night and got 5% drain. Not bad, but all seems to come from 10152 (WiFi) related to Chrome. Why would Chrome be using WiFi at night with WiFi off? Attached are stats.
Maybe searching wifi networks, even if wifi is off.
There's an option to "disable the phone searching for wifi and Bluetooth networks, even when Wifi and Bluetooth are off" (I know that sounds weird but that's how android is made).
