I did the switch to LTE/CDMA and got some better battery life, but it is still pretty bad - the worst thing is that I don't trust my phone to have any sort of battery if I'm out and not near a charger - why have a phone then?
What I have noticed is that I have periods where I know I am running a bunch of things and that the battery is dropping pretty fast. On my ride to work I run Waze, Audible and may make a call or 2. When I get to the office I shut those apps down, turnoff data, location and bluetooth and just have wifi running. The battery app I have showing usage shows that the rate of battery drain barely changes. It seems that once my battery starts draining quickly it just continues until the phone runs out of juice and I have to recharge it. I try to run full cycles - fully charged run to fully discharged - but this is maddeninig. I wish I could figure out what things really cause the rapid draining - there are times when it seems as if it is draining very slowly, but have have not been able to correlate those to specific apps or services amd frankly, this thing should pretty much work they way it did earlier - I shouldn't be forced to jump through hoops to get battery life because I took a half-baked upgrade from which I cannot go back.
