Hi, my Nexus 4 has a big problem. I have huge battery drain in Airplane mode. Overnight (about 7h) it drains 15-20% of battery.
I tried a lot of roms(CM11, AOKP, Stock an now Purity) and kernels (AK, Matr1x, Piasek, Franco and now faux), i tried also safe mode but the results are still the same.
Without Airplane mode (Wifi on (not good signal), Sync on) it drains about 25-30% during the same time.
I used BBS for wakelocks but i don't have important PWL.
I had a lot of KWL by msm_hsic_host and I resolved downgrading baseband from .098 to .048 and now .084.
The phone stays 99% of the time in deep sleep.
I also changed battery with a new one (spareslg.com) and the results are almost the same.
During the day I have 10-12h of battery with 3-4h of SOT.
What kind of problem I have? It's an hardware problem?
I tested new battery with AnTuTu battery tester and the scores are good.
I think that the problem is only when I turn the phone on sleep mode.
Thanks and sorry for my english.
