Seems to be happening again with no major changes to downloading new apps or usage of the phone.
These battery problems are so sporadic with this thing its getting very annoying. Maybe I have a bad battery after 6 months?
Frustrating to say the least as I really was enjoying this phone but its becoming an uphill battle lately in keeping me on Android for my next device.
For me my battery life improved dramatically since switching to Cyanogenmod. I think it's a major issue with Samsungs 4.4 ROM. The Galaxy Note 2 users are reporting the exact same issue now it's hit them.
