If I never turned any of my phones on they would all look like this......I want to be able to use my phone and not have to worry about battery life.
Anyway, if you don't use your phone, then why do you even need it?

If you are going to start a battery thread and brag about how good it is, at least post a picture of you actually using the phone. No one really cares how long the phone will last if you do not use the thing......
If you don't use it, then why do you even need it?

If I didn't turn on my EVO it would look the same as well. Once I would turn it on though, that's when the game changed!
What I would like to see is people show their screen on time and how much battery they have left. That is the stat I am most interested in........I am thinking it is averaging about 3 hours of total screen on time...
I love the people that claim like 7 hours on screen time even with the EVO 3D. Do people really think this is believable with stock batteries that ship with the device.

Yeah, bad signal....might as well forget about that stat. lol
So if a GSM phone has bad signal, it won't be affected like a CDMA phone? If so, wonder why that is.

Here is the thread detailing the known battery glitch
There is no fix for the sprint version yet. Someone made a kernel for the international version that fixes it.
I returned my phone over this issue and I'm waiting for it to be patched before I can use it

Yesterday I kept my 4G radio on all day, sent texts, made a few calls, surfed the web, streamed Slacker and Spotify, checked FB and twitter, and hit 20% after 16 hours.

My stats for today.
Phone of charger for 13 hours and 47 minutes.
Screen on time - 3 hours 25 minutes.
Battery left - 9%
Used wi-fi, 4g, and 3g throughout the day. Screen brigtness set to 40%.

I'm getting a good solid 10-14 hours of use. I'll get 6-8 hrs if I'm pretty much using the phone nonstop.
Have you guys tried the battery calibration app from the market? A fellow xda member made it and it resets your battery scripts (needs root). I just did it this morning before I unplugged the phone since I flashed a new rom.
Battery life on this phone is so much better than the evo 4g. Stock battery life on this phone rivals my evo 4g with 3500mAh extended battery!

Impressive battery life

I have been very impressed with the battery life I've been getting on my Nexus. the talk time has been much higher than any phone I've owned. Here are a few screenshots of my battery life. These two days are pretty much my normal day (lol yeah I talk a lot on the phone).
The first post will be the day that about 50% of the time I was on wifi.
The 2nd post will be screenshots from a day of being connected to hsdpa for the entire day (no wifi at all).
My setup: I use push email, facebook sync, auto brightness, gps on, bluetooth on.
Also, when the phone first came I charged it completely then ran the battery down until the phone shut off. I then charged it completely without removing it from the charger.
Below is the day where I was connected to wifi about half the time:

These screenshots show the next day where I used no wifi at all and was connected to hsdpa the entire time.

I have had mine for 2 days, and I have to say it seems to have pretty good life as well, compared to my Atrix and Note. After reading about all the gripes here,
I was expecting the worst. This battery will more than get me through everything I need to do with it in my day, but I suppose it all depends on what you do with the phone.

Coming from a G2x with a terrible 10 hour battery life, anything I get out of this is freaking fantastic compared to it! I Just wish the devs start getting out some UVed kernels so I can make it longer through the day! I consider myself a heavy user/texter (girlfriend ) and so I'd like to get through the whole day (~18 hours) without a charge I must say, I got to 16 hours yesterday and I was really pleased with that, never had a stock rom last so long without any tweeks!

this is my battery life after first day ....
Not to shabby haha

mysterioustko: I think you're usage is a bit different to the average user. With all that talk time you're using the screen a lot less. It seems the screen sucks a lot of power, and if you're not using it often a full charge lasts 4 to 6 hours longer.

I typically average between 1-2 hours of screen time on an average day. But I talk A LOT each day lol. I'm impressed with the talk time because I've yet to see a phone besides this one that can go 6 hours of talk time in the real world when connected to hsdpa. Also, if you think about it, 1.5 hours of screen time is decent use. It's not a massive amount of use, but it's definitely not like it's getting no use. All in all I have been pleased with the battery life.

I don't know about you guys but im very disappointed in the battery life. With wifi turned on the entire day and no calls, just browsing and chatting on google talk, i got 3 hours 54 mins of screen on time before the phone reached 12% battery. I think thstss pretty horrendous. I was hoping for 7 hours or something of on screen time. My galaxy tab 10.1 has spoiled me i guess. Illl live with it because theres no other android phone im aware of that will give me more, but im kinda bummed about it.

My iPhone 4 has insane battery life... I cant imagine having less. Hopefully they sell larger batteries + backplates for the Galaxy Nexus?

Same here tbh. And the really frustrating part is, I only have 2G where I live so I was hoping to see really great battery life. Hasn't been the case so far though.
However having said that, just last night I flashed XXIK6 and while it's still very early to say for sure, it "appears" that battery life has significantly improved for me. Currently sitting on 91% after 3.5 hours with very, very light usage, IE: 15-20 mins screen on, 15 min phone calls, etc. Nothing to write home about sure, but way way better than before. It would normally be around 80% by now.
It's really sad when the very first thing you do after unlocking your phone is to go into setting to check your battery. Wish I could stop obsessing and enjoy this marvelous device without having to worry about it.

What did you guys do after getting the phone.
Did you charge it all the way to full before use, use and charge at the same time, or let it discharge all the way and then charge it to full?
Thanks.

I would have to say that the GN has the best battery life of any of my previous android phones. (G1, N1, Sensation) These things are very subjective though.

Yeah, and I don't want to lose the thinness of this gorgeous phone with an extended battery, but 4 hours of screen on time? Anyways, can you let us know how that radio works out, I'm not expecting much, but still curious. If it is noticeably better, I will try to unlock+root this phone. I'm just a little scared to brick this 700$ device.

I'm just waiting for mod of web browser that will invert colours. Black backgrounds and white text ...that would extend battery life significantly. I swapped colours on xda app and pulse reader only browser left ha ha

The inverted colours app is already there isn't it? I saw it when I was fiddling about with the browser settings before

Yup, it's under accessibility in browser settings. Great if you read mainly text-only sites since it inverts image colours as well

2-3% per hour idle
I did a benchmark this afternoon for about 8 hours.
ITL41F rom, rooted + dcm kernel, otherwise stock. bluetooth, HSDPA, 1 gmail sync, and a few background sync that is very light.
idle the phone in home for 8 hours. the battery drops about 2-2.5% per hour consistently.

how long does it last with 'constant use' though?... from fully charged, to then having the screen on the whole time & doing web browsing, video watching, downloading, etc... (with data on, not wifi)

Go Comment or Star for Battery Fix

I'm sure we all know that the battery life on the G Nexus is pretty awful, so let's all go star and comment on the issue so we can get Google's attention!
http://code.google.com/p/android/is...s Owner Summary Stars&groupby=&sort=&id=22878
Just scroll all the way down to the bottom and star the issue or leave a comment too.

Done and done... I hope this comes before I need to return the VZ GNex

Hmm, compared to my EVO 4G, I barely had to do anything to this to get the battery life to be very good (estimate 100 -> 0 = 15hours). Maybe I use the screen less than you guys though.

At home, no LTE connection. 5.5 Hours.

On GSM.. battery life is stellar.. keep in mind, like the person who posted above me that if you are in a low signal area your battery will be destroyed searching for signal..

Yeah I don't have LTE where I am either, but I have it forced to CDMA only. Android OS is my battery killer. I usually get around 6 hours before having to plug it up.
I really think that if enough people starred the issue then it will get someones attention! (Crosses fingers)

Please star, but don't comment. There is enough useless comments there already, and everyone gets notified on new comments.

you probably have a rogue app killing your battery. if I let my nexus sit idle with LTE on I get close to 2 and a half days

Hi,
This high Android OS Keep awake time is not specifically about battery life issue.
We are discussing the fact that, because of this, the phone is constantly waking up (wake up state).
And that's should not happen while the device is turned off, for example.
Yes, of course, this will relate to battery life at the end. But, that's not the point of the discussion / bug as everybody has different preference of battery life. One can say 12 hours is enough, while others may say 24 hours is not enough, according their usage pattern.

Yeah I don't think that is the case... even after rebooting it stills is draining even when idle...

i aint charged in 3 days so im all good

This is nothing new. Android is a batt hog, plain and simple. You think google doesnt know this already. Its an "acceptable" item. Where they know about it & it's not the best, but thats what they get if they want a phone thats constantly using the network, has a large HD screen and is so damn good to look at you wont want to put it down.
Quit itchin and get on with it....

I have the extended battery from Verizon so keeping that in mind, my phone lasted 14 hours with 10% remaining with normal use. I stopped testing since I had to go to sleep
By the way I have Beweather and Facebook updating every hour and Pulse updating every 6 hours. I also have endgadget, Cnet, Google currents, Flickr and 500px updating.

So far battery life is a bit lower than I would like but not to a horrible state. definitely going to need the extended battery though. playing around today to see how fast I can kill it.
can't get photo to upload now though for some reason but got 2 hours 10 minutes with 12% remaining. would kinda like to see that as a stat added to phone reviews, minimum battery life. Max is fine but I'd rather know how long it will last with power using.

I'd say battery life was less than great on 4.0.1 but 4.0.2&.0.3 its pretty damn good now my idle usage is next to nothing. 2 days ago i had 47 minutes talk time, 1h38m screen on and about 13-15 hours of idle and still had almost 40% left at midnight.

I think you don't understand.
This is not about battery life, but the high Android OS Keep awake time. Which means your phone was awake when it's turned off.
Obviously, this doesn't happen on my HTC Desire, nor Nexus S with Gingerbread.

I can't speak for battery life on the LTE Nex as i have the HSPA+ version...I've found that the battery life is quite excellent after a few charge cycles...Have gotten 21hrs on a single charge with normal usage...if i'm watchin vids or playin games then im putting my phone on the charger cuz the screen really does eat up battery alot.

New GN owner feedback.

Hello all,
First off thanks to everyone in the community for all of the great articles and information. I struggled with which device to get but settled on the GN. When it arrived I kind of paniced because it wouldn't update from 4.0.1. Thanks to all of you I ended up finding out that I received a YAKJUDV version. With a little research I found out how to change to YAKJU and now all is well.
Not only is "all well" but "all is great"! I am running straight stock 4.0.4, no root, no custom kernel, nada. I do not have any issues with wake from sleep as some have reported, and my battery life is fantastic. As of right now I am on 1 Day 16 Hours and I still have 36% battery remaining. I know that battery life is very subjective but I have browsed some websites, downloaded 10-15 apps. Played a little angry birds. Connected to my job's Cisco VPN and did some RDP work. I have 3 Gmail accounts set to push with calendar & contact sync. I have had Wifi and Bluetooth enabled the whole time. I also have my google voice and google plus account active. I keep the screen on auto brightness. Lastly, I have about an hour or so of talk time during this period. Ohh, I forgot I also have had the Jawbone Companion app installed and connected to my Era, I read a few comments on some sites where users reported the app caused noticeable battery drain, this was not my experience.
In closing, thanks again for all of the info!

Greate battery life
nice....

that sounds like incredible battery life. what was the screen on time? i take it on WiFi the entire time?
either way, its refreshing to hear/see a thread praising this phone.. i am in the same boat as you, i am completely happy with my nexus...absolutely love it. however i had to root/ROM to get to this point but still very happy (i was going to root/ROM anyway)

For me crap battery life at 4.0.1 (and probably battery wasn't calibrated). Once updated to yakju 4.0.4 battery life was much much better. Other than the "screen at low brightness look crap issue" and not too loud speaker (Nokia phones which I came from was DAMN loud), overall very happy with this phone. The ROMs and kernels for most of the cases JUST WORK. And the fact people ask me what phone am I holding is an epic thing when you see people around you having iPhones and S2. May send mine in for a replacement as the top part of the screen has this weird greenish colour. Noticeable when keyboard is in landscape.

the screen on time is 4hrs 2min.

I am not running any widgets, most of my browsing was done over wifi.
I ordered a GNex about 2 weeks ago and used it for about 36 hours and returned it. That one had abysmal battery life. In hind sight, I wish I would have looked closer at the firmware/version type with that one so I would have some sort of reference.
I am kind of pissed that I ordered the extended battery thinking my battery life was going to be ****. I honestly dont think i need it.

I'll check next time i charge it.

did you put it in the charger for short periods of time? if it doesn't get a full charge at once it doesn't reset the timer. you can tell when you are looking at the battery option and the map goes down back up then down again lol... I'm honestly thinking that's the case

Sprint Note 2 battery is a beast!

I put around 6-7 hours of screen time yesterday and still had battery left. Also it looks like the radios they are using are very efficient with very little battery drain.
Nothing scientific to report, but this morning I've used 3 hours of screen time and still have 66% battery left.
Love it!

I am happy to report similar findings. 4 hours screen time and im at 30% battery with 20 hours without a charge.

I don't know why but the radio's are definitely doing better than my S3. I'm picking up Lte more often and its not jumping back and fourth either. So far showing the same as far as battery, maybe even better.

Unbelivable battery on any phone ive come across. No wifi at all and use nothing but 3g and lil 4g to stream movies/drama at my rate im looking to get 5+ screen on time. Thats to me is unbelivable. So far 2:40 hr screen on and still have 58% left. Total time is at a lil over 7. Betterbatterystats say 6% per hour.

3 hours of heavy usage only down 10% with screen brightness halfway up. I feel like its too good to be true... someone is finally getting something right!

Don't get me wrong OG Evo was great at the time but battery on that thing is horrendous. I have to carry a case with 4 extra batteries, lol.

Yeah I bought mine on day 1 and was trying to wait till the next nexus device came out but I sat on my evo and cracked the glass. Anyway very happy with my purchase and I've been riding this phone hard and still at 58%. I know its a 3100 ma battery which is double the evo but I never expected it to do this well on the battery. Very pleased thus far.

I believe that. My 6hrs of screen time was me trying to put it through the ringer.

So far I'm at 1 day 6 hours, (2 hours screen on) and I'm down to 56%. I'm really impressed, and this offsets the sourness I feel with the crippled SIM/wireless charging. Heck, who needs to even charge this thing with battery life like that!?
What really impresses me is the fact that I've been out several times today - yet the battery graph is perfectly steady. Whereas every other phone I've had immediately starts plummeting when I'm on the go and it has to switch towers, etc. I can always take one look at a graph or SystemPanel and know exactly when I was out, but not with this phone. :good:
Samsung really must have done something good with the radio in this thing.

On wifi quite a bit of the time, but still very happy with the battery. Includes gmail email sync, default mail client syncing an imap account every 15 minutes, about 2 hours of podcasts and music, 20 minutes of voice calls, and other misc stuff. No video.

I picked up my Note 2 on Friday, and charged it that night. Saturday morning at 10:00am I disconnected it. I have turned off wifi and SCO so it was running on 3g all day, I decided to not charge it Saturday night to test the battery to see how long I could go without charging. I went a full 48 hours on one charge and still had 11% at 10:00am on Monday. I didn't have heavy use on it, but spent a couple hours browsing the internet and Facebook, as well as 2 hours of Draw Something off an on. Very impressed. I didn't think to take any screenshots, sorry.
