76% Battery - 8h 2m 57s on battery
Maps 28% - CPU Total 35s, CPU Foreground 29s, Keep Awake 1m 19s, GPS 57s, Tx 60k/Rx 277k
Screen 26% - 21m 36s
Voice Calls 25% - 13m 31s
Cell Standby 9% - 8h 2m 57s
Phone Idle 8% - 7h 41m 21s
WiFi 4% - 2h 16m 26s
And I only opened Maps long enough to make sure Latitude was off and background caching was off, and it used 28% of the battery? Seems very odd...
EDIT: Checked my other (personal) Rezound that was hardly used to today as well, same results, Maps is the biggest battery hog with only a couple minutes of CPU use it took up 27% of the battery, and I never opened it even once.
EDIT2: Did a Google Search for "google maps using battery" and low and behold the HTC One series is seeing this as well, so is the HTC Evo 3D and Evo 4G LTE, and handful of other phones too... some comments are that this is being used by other services that use location like SoundHound, Weather, and such, but I haven't used any of these apps today at all, although my lockscreen and homescreen both use weather.

Not sure if this will help anyone, I've been having battery issues, though not because of the maps. Anyway, here ya go.
I had endomondo on for over 3 hours today (my battery life seems to be improving a little, still not what it was on GB) That could have been the only thing that would have used maps. According to GSAM, maps used 2.0% CPU usage:1m 5s, Keep Awake:10s, Number of wake locks 77, number of times waking device:76 The included process are friend service, netowrk location and location friend service.

my extended battery and cover was free from Verizon after some mistakes were made by their people. They like to offer something for free after they screw up.
my spare extended battery is made for thunderbolt yet fits and works in rezound.

And guess what? I rarely use any of them. I rarely need to operate my phone more than two hours away from a charger. How long does one jog in the park? sit in a movie theatre? sit in church? play tennis? and so on.
Think about it. You can charge at home, in the car, and at work if you have a desk job.
Sure, I remember going a few days between charges on my old LG flip phone, but who wants a flip phone now?
My Motorola droid x couldnt go all day on a charge, even if I wouldn't touch it and pretended it was a dumb flip phone. Now we have dual core CPUs and 4G LTE making even higher demands on the battery.
Sure, there exist other phones with larger batteries, but its a trade off. I don't want another Motorola locked bootloader no matter how big their battery is. I considered the Galaxy Nexus earlier this year, but GN owners were all complaining about having dropped data in 4G lte and keeping their phone in 3G helped. Did I want the Galaxy nexus larger screen & ICS or a phone with good working 4G LTE? I figured the phone has to work right, and that's more important. The capabilities to use it on any GSM carrier is also a future plus.
I'm sorry if you didn't discover the rezound's battery weakness before you purchased it. There is no perfect phone to buy. Everyone makes their own priorities list.
I think my next phone will be the rumored HTC phone with a 5 to 6 inch screen, quad core CPU, and 1080p screen resolution. Maybe I'll need a juicepack like this for it.

Personally, for me, constantly plugging and unplugging is a hassle. Being tethered to a charger isn't my idea of a cell phone...that's almost a land line phone. $30 buys an extended battery on my Rezound and also the piece of mind of not having to worry about my battery at all during the day, even on heavy use days. No brainer for me.
There are some folks who have two stock batteries that they switch out halfway through the day...every day. I don't get that at all. Powering down your phone every day to switch out batteries?? Forget that noise. Talk about a pain in the A. I just use the extended battery and never have to worry about the battery.
You had other issues going on. Misbehaving apps constantly running, GPS & bluetooth constantly on, a bad battery...or something.My Motorola droid x couldnt go all day on a charge, even if I wouldn't touch it and pretended it was a dumb flip phone. Now we have dual core CPUs and 4G LTE making even higher demands on the battery.
I don't care what phone you have...if you don't touch it at all during the day, you should have a lot of battery left at night.
