When my 6.1 running pie gets cold, a screen notification wakes the screen up with notification that charging will be prevented. No problem there, but then it leaves the screen on until it is dissmissed. If you are working outside in cold weather with your phone in your pocket, it may be hours later before you see the notification and dismiss it. The screen has been on the entire time, draining the battery. Nokia, please fix this. If it is an upstream problem (Google) then please post where I can file a bug report. You really don't need the notification until a charger is plugged in anyway. Thanks.
