I'm having phenomenal battery drain and huge lag on my Z10 since upgrading to 10.3.1 last week. I used to get a full work shift (about 6am-7pm) out of the battery with moderate use, only plugging in to charge when I was in the office for an hour mid-day and then again once leaving work. Upgraded last week and now the phone is pooched in under 2 hrs. I have to leave the phone plugged in to the 12v power in my work vehicle all day and all this does is slow the battery drain to about 6 hours. I'm painfully useless when it comes to this kind of tech, haha. Does anyone have any suggestions for a noob Neanderthal like me? I've done a few battery pulls and hard resets, stumbled through Device Monitor to close an apps running in the background....problem persists however. Anyone want to run me thru the first steps/questions I should try to cover off?
Attachment 337931 Attachment 337932 This downward drain is happening with the phone plugged in to my 12V cigar lighter adapter, then plugged in to the USB charging port on my Toughbook. I've also tried charging off the Sync USB port in the vehicle with no improvement. These options all worked fine for charging previous to OS update. The phone is in standby all day save for a few texts and phone calls. The up-spikes in charging around 4pm and 6pm are when plugged in to 120V power
