Drained the battery all the way last night and charged it fully overnight - about 12hrs. Status gave "battery full", % was 100, all signs showing it was completely charged.
I'm going to try something today... since I'm in the office today (where I get a weak indoor sign - the building is brick/concrete with steel structure) I've decided to put the phone on Airplane mode, but left WiFi on. Brightness at 25%. GPS *ON* (I don't want to add too many variables). The few apps that have notifications on, like the native news/weather app, FB and weather channel, are set to update no sooner than 1hr or 2hr (if available). I'm going to use Pandora a bit as well, as that's what I'd normally do in a normal workday.
My gut feel is the radio while I'm inside my building, is getting a week signal, and constantly trying to locate a network and/or switch from 3G to E because the signal is so weak (this doesn't happen when I get near the exterior of the building, or outdoors - I don't have the blatant 3G problem others report).
So I'm going to try leaving the radio off completely (airplane mode), but leave WiFi on. If this proves successful in improving battery life, early signs are showing it actually might, I'll try leaving on 2G only while inside my building, and see what happens. Since there is no native 3G only, I can't really try that (as I'd rather have 3G only than 2G only as an option). Will then see how that fares. If positive, I'll go back to radio on (3G & 2G), and try with GPS OFF.
Will report back.
cheers
