Battery life went from good to BAD

[bigdaddie]

We have 3 EVOs. Within the last couple of days our battery life has plummeted. I mean we unplug the phone with 100% and within 30min we're down to 90%. All phones run a different mix of software so it's doubtful it is one app sucking up the battery. When I go into the system info it is Android System that is using all the battery (73%).

The only thing that has changed in the last few days is that 4G became available in my area, but not reliable at my house. The thing is about that though is that the 4G radio and notification is turned OFF. Could it be that by revamping the cell network is causing our phones to go crazy? We also have an Airave so the voice side should be fine. The only thing I have not tried is tuning off the 3G data. I'll try that and post my results.
