Sounds like something is using your network pretty much all the time, myhollowworld2.
For me, GPSToday is the battery killer. On == drain battery at about 10%/hour. Off, drain is about 2%/hour "doing nothing".
2% is Ok, should be able to sit there for almost two days, if nothing happens. 10% isn't good
Constant data is going to be much like GPS fixes, radios will be powered up. Turbines will spin. There will be much suffering. Do you have push email? Bluetooth? Underpants Gnomes?
