4G power usage truly is the problem
Had wifi on with the phone off power at my house and moderately using the phone. After 6 hours, I had only 25% battery loss. Normally when I go to work I don't even get a chance to mess with my phone much so it's just standard battery drain on idle -- usually 10% per hour. 4G LTE truly takes a ton of battery and I know it's beating a dead horse here, but just wanted to relay my findings. I think that if/when they release a true 4G toggle or improves the efficiency of the LTE chip, we will see a dramatic improvement.

I live in a 4g area, and I get about 14 hours of moderate use between charges... I don't use wifi... I don't notice a drain anymore now that my battery has cycled and adapted to my use. I do have background sync off still, (Google sync is always on, and GPS) but I don't need FB and the like to sync unless I'm using it.
I did on accident hit the friendstream icon in the app drawer and not turn it off the other day... Went from 96% to 39% in 2 hours.

I've tested wifi, 3G (usually 1-2 bars), and 4G (usually 1-3 bars), and while wifi adds a bit of battery life, the only conclusive battery draw on my device is the display.
I've gotten 12-14 hours of battery when I hardly use my TB sitting in low 4G signal area all day, and less than 3 hours when I use it nonstop (even with little network traffic). The display is always at 75-85% of the battery usage, and I keep my brightness at 16%, with auto off and a dark wallpaper.
IMO, any power management fixes need to be on the display, not the radio(s).
I live in a strong 4G area (usually 3 bars if not 4) as well and it never switches back and forth to 3G/4G.

depends on how much you use ur phone. When I am at school in or at work I really dont get to use my phone alot. I put it in 3g mode and works great. I still have 70% battery life left after 7 hours it has been off charger already. I think overtime they will probably make improvements to the 4g battery life but for now when I have no need for 4g I turn it off.

I just wanted to throw this out there, took my phone off its charger at 4 am, last night/this morning, and woke up at 12, the cell standby was at 35%, along with the phone idle also around 35%, the screen was way below at 12% (I was sleeping so it was never on) The overall battery percentage was 45%. I have no clue how this can happen with only email on my phone and the HTC weather/clock widget. Do I have a defective battery or something?
