For sure the screen is going to use more than most other phones. But there's a 2100mAh battery in there (at least with the extended). I find it disconcerting that a 2100mAh battery can't run the phone and it's screen at 25% brightness for more than 2 hours tops screen-on time while the 1500mAh battery in an i*hone can last 5 hours of screen on-time at 50% brightness... At least in my experience with having both simultaneously.

I'm very jealous of the Raxr Maxx's 3100mAh battery. And it's still a slim phone.

You can't really make a good comparison between the GN and the iPhone. Especially when you factor in the differences, which are significant.

Regarding the screen on the GN, not only is it larger than the iPhones, but it is a completely different type of technology used.

Ok, I didn't get a screen grab, but if this keeps up i don't know what to do. I went from 100% battery to 62% in an hour and a half. I had Wifi, 4g, gps turned off. All i did was listen to music stored on the phone for about 20 minutes and watch 30 minutes of video stored on the phone. My screen on time was 39 minutes. What in the hell? I was losing nearly 1% a minute watching video. I have disabled facebook and google+ and really have no idea what else to do to be able to use my phone for more than 2 hours. Engadget's review said they got over 6 hours of video in the same configuration as I did. Mine wouldn't have lasted 2. What is going on?

Oh, I'm not arguing at all. Although the iPhone's battery is also significantly smaller than the Gnex's extended battery (2100mAh vs. 1500mAh).

All I'm saying is that I'm disappointed that Samsung and Google can't get top-tier battery life out of a phone which should have room for a decent battery. Yet they chose to put a 1750mAh unit in there - clearly underpowered - just to meet some thickness (thinness) goal. They should have gone the Razr Maxx route and stuck in a 2800+ mAh battery. They knew the screen was a battery hog yet the under-engineered the battery.

Carrying two extra charged extended batteries and swapping twice a day is not really practical for me.

Same issue here. I wonder if some units are defective - draining too much thru the transceivers or something.

I have the extended battery as well and its barely lasting 4 hours with minimal use

 

[Mathmatikus]

49% battery left with 31 min of screen time over 22 hours.

I think people really need to start posting their screen on time along with call usage/music playing. Really, are you using the phone or not? I left mine in my coat all day and got phenomal battery life, imagine that!

I get pretty decent batter life and fall down to 14% after about 2:30 hours of the screen being on and browser whoring and data downloading with the regular battery.

Some of you guys, do you actively use data restriction to help your battery issues.

 

[ultravisitor]

My Nexus has been on 44 mins and already down to 85% battery. I'm not sure if i should try to exchange it or if a ROM will help.

How often are you syncing Twitter, email, etc.?

Thirty minutes of HD video will eat up your battery.

Oh yeah? I turned off my phone and turned it on again a day later and I still had 95% left on my battery!

It was standard defintion, but it is besides the point that this is FAR less than a lot of reviews indicate the battery should last. This link from the Engadget review said under similar settings they achieved 6 hours 15 minutes of video time. My phone, which actually had lower screen brightness, would have achieves less than 2 hours. less than 1/3rd of their results. This indicates that something is wrong. Very wrong. My old Droid with a crappy battery got more play time than that. Now I am wondering if I have a defective battery, phone, or if it is the operating system doing the damage.

Unlocked/rooted my GNex last night and installed the current (1/12/12) version of Bugless Beast ICS 4.03.

I'll give a few days and see how it does. Hated having to wipe the phone, but it was barely useable anyway, so I guess no loss, really.

Hello,

I have noticed with the extended battery, I can not seem to get it to hit 100%. I charge it up all night (7 hours) either with the device powered on or off, and it remains at 99%.

How can I get it to 100% or does it not matter?

[SSHGuru]

It is bad for a battery to charge up to 100%. Most phones will show 100% but are really more like 98% - the Galaxy Nexus is just honest.

So when you see a little less than 100% on another phone it would show 100%

It appears from the screenshot that your phone is awake 100% of the time. Your battery life is a bit hard to believe if that is true.

 

[kath00]

Could you all help me. All of a sudden, my phone is showing being awake all day too. I have a screen shot from about a week ago that shows it only awake at certain times. Battery life was 16-18h that way. Now it's less than 8h and shows awake all the time. I just don't get it. The problem is that I have not installed anything since the new year. What is going on???

I'm assuming that you mean that your Android os is awake all the time now. When this happened to me a cycled my battery (drained from 100-0, then let it charge while off to 100%) The next day my battery was back to normal. Please report back if this fixes your issue.

Have cycled the battery probably 4 or 5 times now. Here's my typical weekday usage from roughly 6:30am - 6pm.

Usage
~45 minute commute to work during which I'll briefly check FB and Twitter, check out unread items in Google Reader and read/delete a handful of emails (Gmail). Maybe a few minutes surfing.

While at work, phone sits mostly unused on my desk, with the exception of a few random checks of Gmail or text messages.

~60 minute commute home. Same use as morning commute, plus streaming iHeartRadio and some light web browsing.

Settings
Completely Stock; Standard Battery
Wifi: OFF
BT: OFF
NFC: OFF
GPS: OFF
Google Location Services: ON
4G: OFF
Brightness: ~10%
Syncing 2 gmail accounts
Facebook auto sync: OFF (manual refresh)
Twitter auto sync: OFF (manual refresh)
Stock news & weather widget refresh every 3 hours
Words With Friends: Background Notifications refresh every 1 hour

Battery down to 51% after just under 12 hours, but only 47 minutes of screen on time. Oddly enough iHeartRadio didn't show on list of battery uses.

How do you change the background notifications refresh on Words...when i try and pull up settings on words with friends nothing happens

Great. Did that last night so I will report back. Also went through my apps and took out auto updates. And rebooted the phone. We will see. So far 18 min of use and down to 85%, which doesn't seem right to me either...
