Last night i charge on 21.30 but this morning i found my battery drain to 34%.
Then i check history detail of my battery and i found my phone always awake from night to morning.
See the image.
Why is this happen? Is this a bug from system?
For info i use FP2 3Gb of ram. Hope i found an answer from this forum.
Now i restart n recharge and my phone back to normal (not always awake)
