Not sure if this is for the QnA section...anyway, yesterday I got a Nexus 7 2012 16GB for my Nexus device collection (used). It was rooted when I got it, with a whole bunch of junk of it, so I used Nexus Root Toolkit and restored it to stock 5.1 (from rooted stock 5.0.2).
Last night however, I noticed two things that seem weird:
- the battery charges really slow compared to my other devices (5 hours for full recharge) and drains quite fast when playing games (compared to the 2013 N7), namely Zombie Driver THD
- self-power off during night charge
While the first one seems normal (it IS used after all so not expecting perfect battery life here), the second one makes me worry a bit. I'm at work so not sure if the issue will repeat, but the battery was certainly not dead when I plugged it to recharge but the tablet was switched off in the morning. Using the original N7 2012 charger by the way.
Any chance this can be ROM-related or is there any known problems like this?
I have had a 2012 N7 in the past but in Android 4.4.4 I didn't have the self power-off problem, maybe a 5.X bug?
