I've noticed a shorter battery life with my Nexus 7 (2012). I spoke with a Google rep at Best Buy yesterday and he said he hadn't heard of that issue on the 2012 model but said they were aware of it on the 2013 model.
Battery life is absolutely abysmal since the latest update. 19.5.3.obakem_verizon.
Ugh...anyone have any clue how to fix Android OS from not taking up 20% of hte battery life...just sitting there doing nothing?
I went to bed with the phone off the charger at 75%.
Awoke to 50%. 25% doing nothing while I'm sleeping.
Prior to the update, lost maybe 8-10% overnight. And I didn't change any apps after the update, so I know it's the OS.
