Battery drain -- please remove mobile data completely
Here is some battery drain test
On standby, CPU has no problem entering deep sleep which is very nice, however, battery drain is still very high, about 1%/hr with wifi on mobile data off and 0.5%/hr on airplane mode, much higher than stock OS(about 3%-5% per day with wifi on).
On airplane mode, the battery drain is caused by ConnectivityService -- lots of partial wakelocks according to BetterBatteryStats. Thats even with mobile data off.
I know there is a LTE version but please remove the mobile data part completely, and maybe a separate build for LTE in the future if necessary.
