...4 hours of heavy usage (wifi connection and 3g on but idle)
Mid to periodical usage could reach 24h.
6th day of usage....
i think this is mediocre for me. please report your battery performance to compare.
Any tips to improve this?
I can get around 8-10 hours with heavy usage... constant music, etc.. and about 2-3 days with light-medium usage.

Hmm so i guess there is a problem with my device.
Great!, and how am i supposed to explain this to the service?
I get about 12 to 15 hours of heavy usage via web, text, and email. If i watch video it's less but I am pretty happy with the battery thus far.

I can only get around 7 hours of use.
I have a problem that if i even dont use it, the battery still drain. I got it full charged and theb unplug it. About 8 hours later, it went down to 50%.
Is there any problem with my device?

same here. i don't know how you guys are getting so much better battery life. i can barely last a day and i don't use it all that much. maybe 2-3 hrs of surfing the web over wifi (not even 3g). i even used setcpu to underclock to 200Mhz when screen is off.
Maybe it has something to do with the very first charge.
When i unboxed the battery was fully charged so i drained it and had it charged for 8 hours. maybe it needed to be charged prior first usage.

Is that 12-15 hours with the screen on? Because that's much more than I'm seeing.
I've done a few measurements just to get an idea of the battery life. They are just extrapolations based on a few hours of runtime for each so they are by no means exact, but my impression is that they give a decent view of real values nonetheless. The battery percentage indicator does not seem to be terribly non-linear.
Video playing (SD quality) with full brightness: 5.5 hours
Video playing (SD quality) with lowest brightness: 9.5 hours
Idle at homescreen with full brightness: 6 hours
Idle at homescreen with half brightness: 9 hours
Idle at homescreen with lowest brightness: 12 hours
Music playing in headphones (screen off): 90 hours
Can't believe how lazy reviewers seem to be, I haven't read a single one where they have properly measured battery life for things like playing movies or reading an ebook. It's all just subjective feelings (which are obviously very unreliable).
All in all I am pretty pleased with the battery life (but I've just had it for a few days). I especially like the fact that it's basically a normal Android phone just with a giant screen and battery. This obviously means that standby and music playing times are going to be excellent.
Edit: Those of you who think you're seeing bad battery life, what does the battery use thingy in settings say? Or is that not a good tool?
I read a post somewhere where the OP was getting horrible battery life and found out that the Gallery app was draining the battery.
The OP in that thread said even exiting the app did not kill it, and it kept draining the battery.
Perhaps you can look into this more. I never use the gallery app so maybe why this is why i get decent battery life?
Edit to add:
Here is the thread
http://forum.xda-developers.com/showthread.php?t=826472&highlight=gallery
If it's this post you're referring to it's by me . The Gallery application shows up under battery use though, so I'm pretty sure that's not it.
Are you sure it's really as much as 12-15 hours with the screen always on? If it were 9-10 hours with brightness at half it would around what I'm seeing I guess, but 12-15 is quite a lot more. Not that I'm disappointed, but if better is possible better is what I want

No not 12-15 hours with the screen always on.... I get 12-15 total... Screen on for usage, off for a while, back on to email and SMS ect...
Ah ok, then there's no discrepancy .
I got 10 hours from full to complete off. I was using it to watch streaming movies on 3g
for a couple of hours and then watch a movie off of the sd card and an episode of supernatural.
After that its just web and ebook reading. Its pretty good. Almost the same as my ipad.
I got a total of around 14 hrs plus with wifi and edge on, screen brightness at 20%, around 7 hrs of standby while i was asleep at night, with 4 hrs of heavy surfing, youtube etc. . . No calls though, only some sms and always on IM with nimbuzz logged in.
What i am seeing is with heavy usage i.e. Multiple apps running, wifi and edge on, i get anywhere between 5-7 hrs of battery life which i think is fair enough for a device this size which am constantly fiddling with.

I've not used mine for that long, but the Battery Left app(which I found to be quite accurate on my N1) shows that for MY usage, I'll get about 25hrs.
I've got the auto dim turned off, and brightness at max. I mainly use mine for checking emails, txting, and a few games.
Nothing heavy.
I'd recomend the Battery Left app to you guys looking to find out your battery life. You DO have to "train" it though, which requires a 100%-0% run for you.
Guys,
does.anyone know, do we need to cycle the battery to give it the best performance?
Example, charge up the unit, then drain it completely and recharge it again? Like in the old days.
mine hasnt gone down much. I have it unplugged at 6am and at 4pm i still have about 75-80% batt left.
This is with about approx. 2 hrs of talk and 30mins of data usage and voice calls paired to my BT headset. My screen brightness is set to 40%

I once got up to 20 hours of moderate usage. But with heavy usage I get about 12 hours or more. I lose about 7% when watching an episode using flash....kinda sucks but I watch a lot of anime online. But I use this as my main phone too. Its replaced my nexus completely. though it was nice with my nexus cuz I could swap batteries. This is how I condition my battery. I let it get to about 2-5% then I recharge it. I don't let it get to zero cuz I heard you can damage the cell. sometimes I charge it to about 20% then I unplug it and drain it to 5% then back up to full. I just kinda switch it up. At first I was getting horrible battery life but ever since I started conditioning it this way I get great results.

What is your brightness setting?
More info about your settings please?
Sent from my Nexus S using XDA App
Auto mainly but i adjust sometimes upwards, as ICS auto brightness can be a bit too dark for me sometimes.
I turn wifi, gps off when im not using it, NFC is off if that makes a difference. 3g is on always. Nothing special, I just "use it" as I normally would.
I think 2 days and 8 hours is pretty good going?

No idea feel free to ask me specific questions!
what apps have you used in this 2+ day period?? games? streaming video? web-browsing? These are the most common uses and they are also the biggest battery killers. I'm sure if I had my phone in airplane mode & barely used it at all I could get better battery life than that. Please give us more details on the specific apps, etc. you ran in this period (to the best of your memory, of course )

Hmm probably only an hours worth of "apparatus" - game, good couple of hours on google reader, facebook etc. no more than an hour on the phone.
my "normal" usage really; not trying to be overly conservative, but also not constantly on. certainly nothing to suggest that I'm getting any worse battery life than I did on 2.3.x
Next time you get this kind of usage from a full charge down to zero let us know your screen on time please.

Battery life stats don't mean much if you don't really use the phone for those 2 days. I'm at 16hours with 66percent left.

Here's mine. A day and half. Similar battery performance with GB even though that Android OS is way too high (higher than Screen)
Yes; that Android OS' looks like a statistic and therefore has a 87.8% chance of being made up on the spot (like that one!).
This is a sample of my battery life and quite unusual for me; Mobile Standby is the highest because I spent five or so hours in an area with very poor coverage, when it could get a signal it was 2G.
Wifi is on when I know I have a hotspot I can use. AutoSync off unless I need it. Bluetooth wasn't used. Screen brightness mostly at the minimum with some time at Auto. Latitude constantly running in automatic update.
Screen on time was 2 hours, 30 minutes and that included approximately 20 minutes of Google Maps (not Navigation).
The biggest difference I've made on my device is to log out of Google+. My use is mostly checking two Gmail accounts, browsing the web, using DropBox / Documents-to-Go, texting, some photography.
Disabling Latitude's AutoUpdate stops the device from waking up with the screen off (all those little blue ticks on the use bar) and makes a big difference to battery life when I'm on the move.
How can you guys take screenshot on stock?
Hold down power and vol. down simultaneously for a second or two for a screenshot.
Also, nice battery life. I've been running about a day with ~50% left, 2 hours of screen time and somewhere around 30 - 45mins gaming. WiFi on all day and calls/texting was minimal.

What's your screen on time during the ten hours?
Hey everyone. I ordered my Nexus 10 in late March and just had a question: How much actual battery life do you get out of your N10? I found that I was barely able to get a day out of mine and am awaiting a RMA replacement. I did a Netflix test, where I charged it to 100%, unplugged and played Futurama on Netflix. I got about 5 hours 12 minutes before the device shut off. I have my screen brightness at 50% and no apps that would cause heavy background usage.
That is pretty good battery life for 50% screen brightness. I still cant comprehend why people need their brightness at 50% or even higher though.

Some people like me use their tablet in brightly lit rooms and outside which means in order to see the screen you need to have the brightness cranked. I never use my tablet in dim rooms.

I'm on on the 2nd charge cycle, but I got almost 5hrs screen time on last charge with about 30% battery left before putting it on the charger. Pretty good in my opinion.

Mostly web surfing, youtube, gmail, G+ and facebook. Not too intensive, I suppose.
I have all sync on except for facebook and display on auto brightness. I also have a strong wifi signal most of the time.
When my tablet is AT HOME WITH ME instead of off cavorting around Samsung repair centers, its day starts about 6:45am. With all my apps and syncing, it lasts me through a work day and then some, going as late as 11:00pm and still being at 30% battery or more, depending on how much gaming I did.

When I am inside it is at minimum (which is still too bright), outside is between 25-35%
For the people who have really low battery, I have a good hunch that the problem is how much wifi sucks up. When I have wifi on I can feel the tablet is much hotter than normal, which means it is dissipating a lot of power. I suspect that the wifi traffic is the 2nd biggest battery drain for people who are browsing all day, the 1st most being the screen itself.

Sent from my Nexus 4 using xda premium
It seems there is a common trend with people who have long battery lives - low brightness. My eyesight is pretty bad so I really can't stand setting it any lower than 40%.
I get about 7 hours before it needs a charge and that's mostly browsing with wifi, which sounds around right according to claimed stats by Google. I'm on around 20% brightness, doesn't need to be higher.
About 8 hours, which is a full workday for me, mostly Evernote/webbrowsing/mails - no gaming. I usuall have ~20% left, so there's 1-2 hours more for emergencies.
I just ran both my original and RMA units side by side, factory reset and unrooted on Youtube playing a 10 hour loop video with brightness set to 100% and at 5h 6 minutes my original N10 hit the 15% warning, the RMA a few minutes later....so I feel kind of bad for wasting Googles time.
I think kernel and ROM have something to do with battery as well as WiFi. I have great signal and use 5ghz and I get great battery life with little drain. Before ras came to the n10 I was using cm and got amazing battery on the kernel it came with but horrible life on paranoid (early build). Also the first trinity kernels had poor battery life for me.

I've had it for around a week now but I've yet to get over 6hrs battery life. I keep the display on the dimmest setting, have no bluetooth or anything on apart from wifi. I keep location services and Google Now off and I use it mainly for Internet browsing, you tube and a couple of bejewelled type games for around 10 mins a day. I haven't watched any films on it or played any real heavy duty cpu smashing games at all.
No matter what I do, I just don't get any more than 6hrs before I get the 15% battery warning.
I don't appear to have any wake locks, the battery graph shows that when the display is off, the tablet never seems to be awake.
I installed Better Battery Stats but I don't really understand what to look for.
Can anyone suggest anything before I give Google a call and they tell me factory reset and try again?
Any help would be greatly appreciated!

Mind posting a picture of your betterbattery with:
-Partial wake locks since boot
-Other since boot
If you use it like you explained you should be getting more than 6 hours.
I'm using a custom rom and kernel so that might explain why I can idle for an entire day and only lose around 6-8% depending on how many emails I get.
Typically I get around 8 hours of use which includes watching movies over stream, YouTube, flip board, email, xda surfing, and a few other things.

Charge your device to 100% and use your device the way you typically have been. Once you get down to red numbers, post a screen shot of the regular Android system battery usage. That might give a better picture of what's going on.
You can also charge to 100% and disconnect from the charger and let your device idle. Better battery stats is a better tool to use when you aren't using your tablet, and you are experiencing battery drain.
Also, you didn't mention whether you are stock, rooted, or rooted and ROM'ed. Please do that and we can go from there.

You said 6 hours battery life in OP, implying you were getting that battery life for the device... ._.
Congrats. You have a normal device... People may be using screen filter to get those results, but why not just enjoy the screen instead of gimping it for an extra hour or two of dimly viewed screen...It's not too tough to charge it overnight.

And if its really that big an issue, go get KTManta, Franco, or any kernel that lets you reduce the maximum clock from 1.7 to 1.3 or 1.2 GHz. I have benchmarks for the Manta at frequencies ranging from 1.2 to 2.1GHz and there's not a big difference in performance.
Hi!
I have a relatively new Nexus 4, which I got NIB about 6 months ago. The battery life is ok for a phone with these specs, it easily lasts 1.5-2 days, depending on usage. But my screen on time is really bad: I rarely get more than 3 hours, usually more like 2-2.5 hours when reading emails, Twitter and Facebook (no games). Everything is fully stock, I have very few apps, and other than really bad screen on time can't complain.
Reading about people having 4-6 hours of screen on time, I wonder what I could do to improve mine. I'm so upset because of this issue, that started thinking about selling my Nexus and buying a Motorola I would appreciate your suggestions!

Depends on who you ask. Some says flashing a custom rom will help, some says flashing a custom rom with a kernel, and others say just a kernel. As far as the best option, you will have to experiment to find the best configuration for you.

There are the usual fixes:
Turn off as much syncing as possible
Turn off location / bluetooth / nfc
Turn down brightness (although auto is relatively smart)
Beyond that, not sure how you only get 2-3
You can try apps that monitor battery usage more closely to get a better idea of what is actually draining your battery so quickly

Well, it would seem that the screen eats the battery, as I only get very poor battery life when the screen is on, otherwise the phone lasts ~2 days on a single charge with WiFi, 3G and GPS on. The brightness is set to auto, but I still get only 2-3 hours of screen usage with really simple apps (Chrome, Twitter, sometimes Facebook) and then the battery dies.

2-3 hours of screen time is normal.
You got to take into consideration;
this phones battery is NOT big, its small.
This phone has an LCD screen, the power is going to run out much FASTER than OLED screens.
Be happy you get 2-3 hours. Some people can barely get one.
I get 4+hour but with 6 hours total battery time. I can also get 1 1/2 days of light usage.
This phone isn't going to give you 5+ hours screen time on top of 12+ hours of battery life. Its just not gonna happen.

For the most part, I don't keep up with the amount of battery life because my phone and tablet is never too far from a charger. Although I have watched the battery drain while charging when I watch a lot of videos on YouTube tho.

You might try a custom kernel that's optimized for extended battery life. You'll get small but noticeable improvement, just don't expect miracles!

Looks like my Nexus will be replaced with a Motorola after all
I get about 4 hours of on screen time with moderate gaming with CM rom.
Biggest difference compared to stock is that a lot of the services that run on stock are not installed or turned on.
Apps that constantly check in email/facebook/etc.. can drain things as well. Increasing the interval between checks, or disabling it altogether and just doing it manually would help.
BetterBatteryStats can help you narrow down what is giving you the biggest drain.

i can agree with you: my girlfriend and me got both a nexus 4. she has to charge her phone every day when she comes from school and also get not more than 2,5h screen on time. her phone is completely stock and loaded with a lot of beauty-apps, lol.
i rooted my nexus 4 and run paranoid android beta 6 with the stock gapps package and the hells.core b44t3 at the stock settings and iam getting at least 5h screen on time when useing my phone for about 20h-30h. iam just useing whtsapp, messenger, facebook, instagram, web browsing and google+, not playing games with it. i also tunred 3g off and use only wifi or 2g, because these apps dont need 3g necessarily.
