I am looking at the battery drain when the screen is off : i have already activated greenify but nothing....here's my battery statistics
The system is the main "drain"
I have been testing sMiui and android L on my mi4 in TDB for 1 month .... Every switching from rom1 and rom2 i have to dirty flash again the systems because the recovery at the end fix the TDB but no miflash no factory wipe.
