I've been using my Verizon Galaxy Note II since mid June (I got it brand new). It's rooted and always has been, however a couple days ago I was running Jelly Beans build 21 and I ended changing to the HTC Sense Recent apps (I don't think this is a problem, but a coincidence) and after a day or so I plugged my phone into the charger before I went to sleep. However I realize it wasn't charging. I tried unplugging it and plugging it back it and it didn't charge. I changed outlets and no charge so I restarted my phone and it started charging. Ever since then however, my phone has been dying quickly. Maybe losing 20% battery life within an hour. It also charges really slowly now, too. I used to get from 0% to 100% within 1.5 hours to 2. Now I'm at 25% and it says it'll take 3hr 45m to reach 100.
I don't know how to fix it. What heats up is not the battery, but the GPU/CPU area. I changed ROMs and it didn't fix. I also used ODIN to go back to unroot/stock which SEEMED to have fixed it (I lost 3% in 40min compared to 3% in 5 or 7m). But after using it for a little while, it seems to happen again. I then re-rooted and restored from back up to the new rom (not JB 21) and it's happening. I'm currently charging it to 100% and then I'll let it drain and monitor it just in case there is a main problem. I'll also try a different cable tomorrow.
However, I was wondering if this has happened to anyone else or if anyone else has suggestions?
As an FYI, I've
- Turned off DATA
- Tried charging while the phone was switched off (it does cool, but charge time doesn't seem to improve which might be because of the 700-900 amps I'm getting.)
-Underclocked to 1.4ghz and undervolted by 75mv on everything
-Turned on Power Saving mode
-used Greenify for many apps
-Let it go from 100 to 1% in order to correctly monitor battery killers
-Tried a clean unroot, back to stock, root, clean flash. (I've done it all except the clean flash [I restored a backup])
-Other things I can't think of
