Every night i leave my phone with 2G active only: wifi, sync and 3G data is off.
Before upgrade to 4.3 it wopuld use 2 or 3% overnight, in about 8 hours.
After upgrade to 4.3 battery drain is now 8% in 8 hours.
I have installed batter battery stat and I have found out that the cause may be LocationManagerService that in 8 hours has issued partial wakelocks for 15 minutes, with a count of 1,000+ calls for a total of 30% battery drain.
