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, Faux, Piasek, Franco and now Matr1x), 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?

Thanks and sorry for my english.

Hi fc_themaster,

Do you close your apps/games before you sleep? Do you use Task killers or Greenify to boost your battery?

yes, I use greenify root donation.
I've also tried with clean install with no apps and in safe mode...
However I always control my wakelocks with BBS.

Hi, these are the screen of this night in airplane mode. I've lost about 11% (from 61 to 50)... no PWL, a few KWL... all night deep sleep.
Moreover the charge level is updated after a few seconds... when I unlock the screen the charge level is 61%, but after 7-8 seconds it drops to 50%.

2 things you could make sure about:
1. Scanning always availble is turned off. Settings>wifi> menu > advanced. also I turn off "keep wifi on during sleep"
2. if that doesnt help try going into recovery and wipe your cache and davlick cache.
