@allen099.... man, it's sounds like you and I both have similar battery struggles... otherwise, my Nexus is solid and I'm reluctant to send it back...
I was on a roll yesterday with my "experiment" (ie. turning on airplane mode, ie. turning off cell radio which in a weak signal area to avoid hunting and switching)... but seems like if I make any amount of phone calls, even if just 30min worth, battery life take a dive...
as it stands, i can only get about 12hrs of life at most....
I'm wondering those getting 1full day or more on a charge even make one phone call to get the battery to last that long...
i also noticed that using the music player uses more battery than using Pandora... at least that's how it seemed... is that possible??!! all I can think of is streaming is in a format that requires less processing than the .m4a files I've got on my SD card...
I've cycled yet again last night (full drain).... I'll try again today... leave GPS off entirely.... i might even just keep plugged in day and try to keep plugged in as much as possible over the next 24hrs... i have charger at home, in car and at work... so should be able to keep it plugged most of the time today...
HTC should consider opening up local repair centers in the larger cities, at least to avoid the shipping back and forth crap...
