I agree with MBM. At first my battery life was HORRIBLE, even in idle. After a factory reset and some time to sync it has got a little better, especially on idle. I can set my phone down and not touch it....come back an hr later and it's only lost 3% (if on wifi). Time will tell but I'm guessing battery life will be comparable with GB.

My personal Rezound the battery life seems very hit and miss, today with minimal usage I used less that 7% in 4 hours, yesterday it was more like 20% with similar usage. I still haven't been able to put my finger on the battery drainer yet, but I will...

On my work Rezound, which has had less than 15 apps installed ever in it's life, the battery life has increased noticeably over Gingerbread, leading me to believe that ICS is not the real problem, but misbehaving apps is the battery drainer.

Will do... I have also noticed that Maps seems to be waking the phone a lot, and activating the GPS, and the amount of power it seems to draw for such a short time seems very high, will try to look at that too. Might try uninstalling updates and disabling for a bit, but it's usage seems consistent across both of my phones, and only one is having moderate, inconsistent battery drain issues, the other one I have noticed the battery life has increased significantly.

I think the battery use is higher. I've had to charge my phone more often, and It gets hot.more often.

yea, on verizon all the reviews say the battery sucks, only a few hours of screen time, that seems very bad, wonder if i would get a lot more with the 2700mah battery? or is the nexus has best battery life

I haven't gotten the latest OTA because i flashed the first leak back in march, but i would say that my battery life got much better with ICS over GB. Still hard to make a whole day with much use, but it was better. Seems like i used to have to charge at work, but after flashing the leak, i was able to get home with maybe 15% battery left. A difference of maybe 20-30% i would think. Ballparking as a layman so don't beat me up.

are u on stock battery or using extended

I use the stock battery. I have often considered getting a second one as a back up, but never pulled the trigger. I think the phone is fat enough without the extended battery, and i thought it would be good to always have one with a full charge when it is most needed. I figured on just keeping the extra in my briefcase or my car, and not fattening my pocket.

The superior screen of the Rezound makes the battery life not quite the best. It's one of the trade offs one has to make.

Extended battery.

Google Maps definitely seems to be doing something in the background, not a real significant amount by itself, but compared to other things it's really high...

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.

Phone size and battery life is another trade off you have to make.

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.

Do you use the extended battery?
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.
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.

what case do u use with ur extended battery? does it protect the screen and rest of the phone well? like the defender by otterbox

I would consider a brick in my pocket for a whole day a bigger pain than switching a battery. Just my opinion. Curious, Do you carry your phone around in your pocket. For me the extended battery just made the phone too heavy and bulky for my pocket.( i tried my buddies for a week.) I can see the extended battery for hip use maybe. Powering the phone down to switch the battery isn't that hard for me. Neither is plugging it in when i spend time at my desk. That's a pretty rough comparison to a land line though, since it can be plugged in almost anywhere. I've never been more than 8 hours away from and outlet or usb, and I spend half my time working on roofs.
