[Nexus 4 Q&A, Help & Troubleshooting] pancham7:
I have been experiencing a massive battery drain. 20% overnight drain with wifi, mobile data and sync ALL OFF, also wifi scanning always available is OFF. Have tried clean flashing different ROMs and Kernels. Phone is entering deep sleep. I feel its causing because of No or Unknown signal. But I have a very good signal. Full 5 bars and receiving calls and SMS normally. BBS Stats is attached as well. Kindly help me.

PS: Facing this problem since I got ported to another service provider.
