I'm having very poor battery life compared to my samung galaxy tab 10.1 and my motorola xoom
Im getting about 5 to 6 hours of screen on time. Most of the time I browse the web and play some gamesWith the galaxy tab 10.1 I used to get around 10 hours abd wih the xoom about 9.
Is just me or are you having te same problem?
I also can't see the battery usage stats.

For battery drain, are you in balanced power mode? The display would be the next thing I would check. Make sure your do not have the brightness up too high or that new IPS+ brightness feature turned up for outdoor viewing.
im using most of th time nrmal mode and using my tablet indors with low brightness. Can i calibrate my battery or what should I do?

even with low brightness, having it in Normal mode drains the fastest. normal mode is when Prime is running at Max power. combine that with web surfing slot and that's the cause. web surfing puts a strain on battery as its constant using more n more ram n rendering pages, etc.. even so it seems you should be getting better battery life even with that configuration. do you have alot of Widgets set up to update very frequently? do u have your email set up to update frequently? do u have something else rubbing in the background that you're not aware of? all of those things will cause battery to drain faster.
if you want the best battery life and power use balanced mode instead. even in balanced mode, its far more powerful than the galaxy tab or xoom you mentioned. make sure to check for those other things mentioned also. you should get better battery life than that though even in normal mode. you could also decrease the display timeout.
since the normal battery usage setting that shows apps battery usage is bugged in HC in prime, go to the market place. download a free app called Android Assistant. its 18 tools in one. on there it has an app battery usage sections and you can check there to see what's been draining battery the most aside from display. .

plus technically its still too early for battery to be fully broken in and calibrated yet. it has to go through several full charge and discharge cycles before it gets to optimal battery performance.
I'm at around a day on normal with auto brightness. Use it mostly to browse the web and xda. Play a few games as well.
Yeah battery isnt as good as everyone makes it out to be. Since i got it on dec 23rd I have had to charge it up every night.
In the morning its at 100% (10am) then I take it with me to work, usally dont even have time to use it but sometimes i do. On a day that I dont end up using it at work at all, by the time I get home its at 93% (decent for being idle 10 hours, my hp touchpad is around 95% after my 10 hour work day and ipad 2 sits at 99-98%). then i start actually using the device, 10pm - 2am and im down to 50%. This is with very light use, checking email and usally watching a movie on the sdcard. By the time i goto bed its about 20% (3am).
So overall the battery is "OK". Gets about or close to what other tablets are getting in terms of battery life. My ipad 2 gets about 10 hours no matter what i do (gaming, browsing, videos). Asus Prime gets about 7-8 light use (email, sdcard movies, sd music) and about 6 hours heavy use (gaming and browsing).
Settings on my PRIME:
Balanced mode
10% brightness
super IPS + off
GPS off, Bluetooth off.

So then i guess every tablet can run for 12 hours or more in that case...
The prime is advertised as having 12 hours battery life when your using the device, not in idle... you are obviously trolling anyone that has something bad to say about the prime, Its shameful.
This is with heavy to light use. Wifi it always on. Screen set to auto. On normal mode. I have only charged it when the battery dies completely and don't unplug it until it is at 100% for awhile. There was 1 or 2 times where I charged before it died completely.

In all honesty, considering how much the device lags at times according to reports, I can't imagine running it in any other mode than Normal. I'd understand if the other modes would be lag-free for light activities like browsing, but they are not. At the moment, Normal is the 'best you get' in a bad situation.

Umm, I don't know if your aware... but any tablet can do that if its just idle all day like that...
I always drain my tablets once or twice a week till they shutoff and charge them up to 100% and unplug (if you leave them charging over night or drain them to 0% every night it will degrade).

this is funny as I run mines in balanced mode most of the time. its always lag free. what reports of lag you speak of? lol even when I put it in battery savings mode its smooth as hell. these so called reports along with others really have people who don't even own device misinformed. most so called reports here on general show device moves fast n smoothly. there has only been 1 video of so called lag in browser and that was trivial. as people thought video didn't really represent what was going on. other than that, there has been no proof of so called lag. especially coming from major reviews before release and after. I've basically used my tab nonstop and have a whole lot of stuff installed on mines with Widgets and live wallpapers and no lag at all what so ever. it'll be different of proof was out there bit there isn't. as far as memory goes funny how some new tabs announced with 2gb of RAM and now suddenly 1gb is not enough or its a little..lol. of course o would rather wish this had 2gb ram tl start off with but it doesn't. from what I can tell it doesn't hamper performance at all and seems to be enough.
ill just end this here. I could go on n on debunking these so called reports but not worth the time. it'll be different if it was a valid argument like GPS. which we know isn't working properly. as far as wifi, lag n everything else goes, its all trivial at best. as my device performs perfectly aside from GPS, which I've never fully tested yet. I'm a good candidate for using the tablet more than most considering use it for work also. so I'm day in and day out on this tablet. even developers who have posted reviews of prime are more than satisfied with performance. tell them the so called reports n see what they tell you in return..lmao
yup horrrible battery life #sarcasm
My battery life is about 6-7 hours so just like in TF101. And it was supposed to be so better....

Not if you are formatting battery for first few times - it is said to do like this in manual.

Do not believe this. It depends on how the person count it. I count ONLY the time of "Screen on". Some people makes Prime to sleep for 10 hours + work of 4 hours and they say their primes work for 14 hours
So after using the tablet if in options (battery monitor app) I see 6 hours of display on and I have 3% to go then I can tell my Prime works 6 hours on a single recharge.
That is the way it should be counted. Because you can;t work on tablet when screen is off right? (maybe if you listen to music)

And? What's wrong with this? It's normal for webbrowsing.
Well we have different ways of thinking when saying battery life.
I'm always on Normal w/ IPS @ about 20%. I've never had to use Super IPS mode even on a sunny day. IPS to 80-90% in the bright sun and is very lucid (and I live in AZ where we've been having 85 degree weather lately!)
That being said, I get so much out of the Prime and I've only drained it twice. Last night I drained it after 2 days of decent usage and no charging. I've been marathoning 'Homeland' on my laptop and using my Prime for everything else. I'd say I've had about 16 hours of entire usage over the past couple days. I did power the Prime off before sleeping to compare it's percentage loss to when it is asleep to when powered off so perhaps it's not a fair assessment, but I did use it quite heavily including streaming youtube, regular browsing, downloading apps, trying to get a lock on GPS and playing a flash game.
I think we should measure battery life only with screen on time, the problem right now is that the prime doesn't show the battery stats. Anyother way or app to have battey stats?
I ,am on it a lot, between GPS and general usage, ,but this still seems like too fast to drain compared to what others here have said. I had this problem with my Atrix too, maybe i am just destined for bad luck with battery life
Do you use anything like juice defender. This app literly doubled my battery life!

Apps like that only increase standby battery life. Everything else is very minimal.
And I'm not happy with the battery life either. My phone is plugged in right now and the battery is actually going down as I use it.

If it's notbthe stock charger you areblikely not using a rapid charger.
Sent from my SGH-I717R
I pull mine off the charger at 7:00 and at 3pm or so it's down to 85%, I'll put it on the charger at work until I leave around 5-6pm (mainly because I'm used to having to do this on my previous phone) and at night if I'm not using it constantly it's around 70-75% when I plug it in at bed time.
I suspect anyone getting that bad of battery life must be using it constantly, ie: Playing games, browsing, trolling facebook, etc.. Even in the "new toy" stage I'm getting great battery life.
FYI I don't have LTE, but do generally have good 4G.
You honestly can't use any phone on GPS without external power and expect that you're not going to discharge quickly. Assuming that you are running a car charger during GPS and just didn't say so, search the i-717 threads, since the topic has been well vetted on what chargers are more effective,etc. There are definite differences.

The fact that there are people out there that get really good battery life means the problem is you and not the phone. If you refresh facebook every minute of course your battery life will be crappy. apps like juicedefender are just marketing crap. as long as there are no running apps in the background that eat your battery, you do not need any juicedefender or tasker. also setting screen-off behavior to conservative on set cpu helps improve battery life.
When I first got my i717 and was using it on the stock rom I had pretty terrible battery life. I take it off the charger at 5:00am and had decent battery life (around 5 to 7 hours without GPS) but I use my phone a lot for internet/email. I think your battery life is completely normal given your usage.
Most people get about 5hrs screen on time. Total on battery ranges up to about 24hrs, but only if the screen is off at least 19 of them.

5 hours of screen time AND 19hours standby sounds incredible
would sure like to see screen shot as well
and def dont think 5 hours is any type of avg
I had GPS running on my phone for 4 hours today, had blue tooth on half the time without knowing it, sending text messages, making two 5 min phone calls, checking maps, checking FML and reading a book for about an hour and drained down to about 70% and I have the brightness set at auto. I would exchange it for a new battery.
On average with several texts per hour, several 5-10 min phone calls, taking a few pics and uploading them to picasa, checking facebook, updating status and checking emails I can pull off the charger at 630am and still have 50% battery (at least) by 630pm.
I do have the juicedefender (which isn't crap, it turns off signal after so long so you aren't trolling for signals when you aren't on the phone).

I had a ss of my buddies yesterday, but can't restore mms lol. There are plenty of other ss in the note section. He was at 22+ hrs with about 4:30 of screen on and some % remaining. I have to charge around 7-9 everynight at 4-4:30 hrs screen on, but my use is pretty heavy. I sync 4 gmail accounts, a separate GV, 3 calendars, and several apps.
If yours is much worse than that, you likely have a few troublesome apps or are playing games. First, after a full charge, reset cpuspy timers, lock it, and set it down for a few hours (I know, impossible). Then check to see that your CPU has been in deep sleep about 95% of the time. If not, use better battery stats to see what has been request wakelocks. Not only the most total time, but the total number. Any app that looks outrageous, freeze it or uninstall it. For system processes that look troublesome, Google. You can often find simple tricks online that will tell you what's causing them to go crazy. Beyond that, turn off syncing of anything that isn't needed or doesn't matter (like Facebook), and uninstall stuff you never use.
Another slight help is the brightness widget (don't use the actual widget, just put the app on your homescreen, it works the same) or dimmer in market as they can both set the brightness to a value of 10 (Samsung lowest stock is 20), and even if you can't tell the difference, it helps. Jkay settings in saurom can set the auto brightness profile slightly darker than stock. Umm, and the obvious, use less Widgets, longer sync intervals, processor scaling and speed profiles, and buy a couple rapid chargers, wall and auto.
A couple things to note after seeing a few of these posts...
BT can be on, but without it searching, connected, or listening it's not active.
GPS isn't active unless its in use aand you see the icon in the notification bar. That being said, fb, websites, and many other apps that request location will activate it.

YOU MUST CALIBERATE THE BATTERY!! I have no issues I use my phone heavy all day and get 15 hours and I still have 20% left. All you have to do is
1) Charge you phone until it says "charged"
2)Leave phone plugged in and power off and let it charge until the battery meter literally says "100" (screen will sleep so you can check with volume rocker to light screen)
3) power on phone and let boot and than power off and wait till you see 100% again
4) now keep doin this and you will notice it will start displaying "100%" faster and faster usually takes 6-7 times cycling like this
5) After you do this download Battery Caliberation (root required) app from market and hit the caliberate button and boom your good to go
I do this on every android phone I own when I flash a new rom or purchase a fresh one. Everyone should do this everytime you flash a new rom and I can CONFIRM significant battery longevity on all my android phones I have done this with
You only have to do it once so just get it out the way and you'll get through a whole dayand have some juice to play with.
I get 15+ hours and do not any battery juice defender apps

Just to be clear here, Tasker has nothing to do with battery life. It doesn't hurt it, nor "help" it. However, you certainly could write tasks/contexts that would decrease battery life, and there are a few scripts out there which do silly stuff like autokilling, etc... But if we're talking "battery savings", Tasker and JD do not go in the same category.
IMO JD is only useful if you're frequently in an area with no signal, like you work in a basement or deep inside of a solidly constructed building. Since you mentioned Tasker, in this context it does help me a bit on battery because my wifi turns off when I leave the house, but that's also something JD can help with. If you don't have a wifi connection it'll turn off wifi (and I believe turn it back on periodically to see if there's one available?) I don't use JD, so can't speak too much for it.

Hour? Hour and a half? I'm working during that period. I usually hit news sites and G+ when I'm first at my desk in the morning, so that's 30 minutes or so off and on looking at it, then perhaps an hour over the rest of the day, sometimes more at lunch.
I'll look closer today and post back.

Hi
I have a question regarding the battery life on the prime.
ASUS advertise up to 12 hours on their website...
I'd expect to get at least half that with normal use..
How long does your battery life last with normal use?
Like ebook/pdf reading, some browsing, some youtubing and maybe some
light gaming?
I dont have much running on mine, i always try to kill backround processes.
I always have it on low brightness and turn the wifi off when not in use.
I usually dont make it much longer that 4 hours with light use... maybe 5 hours.
I use mine mostly for pdf/ebook reading. A little browsing/youtubing here
and there...
Is this normal or do I have a defective unit that I should replace?
Other than this I have no problems with the prime.

My wife and I get about 8 hours heavy use. Video, nook & browsing.
With similar/more usage than what you describe, I get much more than advertised...at 70% right now on performance mode at 7 hours at full brightness with wifi never sleeping. Keep in mind their 12 hours was playing video the whole time. I'm ridiculously impressed so far.
Sent from my Transformer Prime TF201 using XDA
I can't tell you exactly how much I get, because I never got down to under 20%. To be honest I mostly use it with the dock, watching video and browsing outisde (+IPS) on never ran into battery issues after 2-4 hours.
So I never every until now worried about the battery, it was just there.
it really does last quite well, im used to charging my phone up every night and i cant get this thing to drain quickly, i wanted to do some full drain cycles on the battery and it actually took hours and hours to empty it.
you wont be disappointed!
Honestly, coming from an Apple employee, it kicks the iPad's ass not only at battery life, but at charging too. This thing charges in just about the same time it takes to charge an iPhone.
Wow.. 8+ hours... I dont see that happening on my unit.
I think ill try a factory reset and if that doesnt help
I think i'll have to return it for a new one.
Thanks everybody for your comments
I get about 16 to 1 day and 6 hours with the dock (That's using it very wildly, meaning not sparingly).
I surf alot, watch videos, play games, test settings.
I use IPS+ sometimes only but most of the time I have my brightness level on about 70%
Cheers!
Well, just did a factory reset, down 6% already after ~25minutes.
I think i'll see if the store will let me return it because of
unsatisfactory battery life
I get like 6 hours on screen time generally....pretty bad. Probably a lot of bugs to work out with the tegra 3 still, hopefully Asus is working on it. I do not even do anything that intensive, just web browsing, chatting, taking notes, don't even watch videos or play games too often. Battery life would probably plummet if I played games.

Or even anybody with similar results on their prime?
16,5 hours since charged, and i've got
2h40m Screentime
3h24m WIFI on
61% charged
Usage: Watching a movie, surfing, playing around with the system;-)
Fully charged at 1pm yesterday, after flashing Primulous from cwm touch, i have been benchmarking, browsing, took about 10 min of 1080p video, running wifi analyzers to configure repeater in my house, left on overnight, on balanced mode. Woke up at 5am, have been youtubing, browsing. Its 8:30 and battery just hit 20%
I AM IMPRESSED to say the least, battery life is so good due to running "minimal" when flashing Primulous, wasn't quite this good when on stock, with bloated apps
I have just about every tab on the market in the past 2 years. iPad, iPad2, Transformer w/dock, Acer, HTC Flyer, Kindle Fire, Galaxy tab 7, galaxy tab 10.1 and now the Prime w/dock. The Prime battery outlasts all of them except the gTab for me. I get about 2 days between charges prior to the dock and about 3 with the dock. Stats right now are at 70% tablet 92% dock with 10h 36m on batter and 2 hours of screen on.
With WiFi running at 10h and taking up 81%of the battery. I switched it off this morning to see if I get an improvement since I dont use it and I definitely see a HUGE improvement.
I've always had issues with leaving my WiFi on connected all the time. Lasts about 4-6 hours with WiFi on all the time. Now that I have it on JUST when the screen is on, it lasts about the good 6-9 hours. Anyone having this issue too?

Hi
I have a question regarding the battery life on the prime.
ASUS advertise up to 12 hours on their website...
I'd expect to get at least half that with normal use..
How long does your battery life last with normal use?
Like ebook/pdf reading, some browsing, some youtubing and maybe some
light gaming?
I dont have much running on mine, i always try to kill backround processes.
I always have it on low brightness and turn the wifi off when not in use.
I usually dont make it much longer that 4 hours with light use... maybe 5 hours.
I use mine mostly for pdf/ebook reading. A little browsing/youtubing here
and there...
Is this normal or do I have a defective unit that I should replace?
Other than this I have no problems with the prime.

With web browsing, ebook reading, and some YouTube I get 12-14 hours when my screen is set to "power saver" performance mode and with the screen at about 25% brightness. If I have the Prime plugged into the keyboard dock I get 15-18 hours depending on what I am doing.
First thing. Don't kill background tasks. Unless your Prime is seriously suffering performance issues you should ignore any background task that is running. Compulsively killing tasks will actually drain your battery faster. Do you have a lot of apps syncing? Twitter, Facebook, Instagram, etc? If so turn off the ones you don't use often or at least set them to update no faster than once an hour. Also, set the WiFi to turn off when the screen is off, this will improve standy battery significantly.
If you keep getting battery drain, before you return the Prime do a factory reset and see if that solves the battery drain. There could be some system process that isn't ending correctly and keeping the Prime awake. Factory resets are wonders at solving this kind of glitch.
Well having bad luck with my new TP. Seemed that .21 update caused battery drain on my TP. Today I only used the TP for a total of 1 hour for sending email, few web pages and battery is at 14%. This no good for travel or to use on the road. It has been on battery for 10 hours, but out of the 10, only 1 hour has actually been on.
I do notice a few things. Even though screen is off, the right side top feels warm to the touch as if when you use the tablet. Now I am thinking something is running none stop. Any good apps to check this?
Also notice that even though I am in the home screen, I see the arrows in the wireless icon showing as if data is always going up and down. So this could explain the massive battery drain. My HTC Jetstream only does this when opening web pages or sending email, which the TP will do but keeps flashing as if is always sending something. I have restored 3 times already. Now I will restore and not install anything including my account to see if it is the TP that is defective.
Anyone seeing this with your TP? I am ready to take this tablet back.

could be .21 or could be battery is just bad. What does usage look like?
I am not having that issue at all. I unplugged mine around 7:30am on the 2nd and it is now 12:05am on the 4th and I am still at 36% with performance mode on most of the time. A lot of time has been spent playing Asphalt 6 even. Plus, my normal web browsing and just messing around. I do have a dock so I know that attributes to some of my excellent battery life but not an extreme amount. It is only said to extend it by 4 hours of use.

Seems like something else is causing the battery drain. Like I mentioned, the top right side back, you can actually feel it sort of warm, compared to the left or the complete back. I know that the back feels warm after you use it for a while, but shouldn't feel warm after sitting with screen off.
Too bad only used for about an 1 hour a few minutes today and just shut off on me as I was responding.
Id use CPU spy see if that shows anything weord but defo sounds as if a app is eating all ya battery up if u find nothing try flashing firmware next one down see what happens or couldbt u try a different kernel

Mine doesn't get warm and I still get about 6-8 hours as opposed to the 10-12 I got before.
I've been noticing that Maps/GPS always seems to be running even when I have GPS disabled.
I was so happy holding my Nexus10 in my hands.
But now, I'm pretty disappointed.
My fully charged N10 went down to 8% with Playing 2,5h Need for Speed Most Wanted + 2,5h other Display-on Time (mostly surfing, News App and Facebook Chatting)
I mean, FIVE hours? Come on Google, thats not even half the time I can reach with an Ipad

You iPad does 10 hours of gaming?
The ipad does have a 11560 mah battery and a screen that needs less back lighting. Also the cpu probably uses a good chunk of the battery on the nexus 10. could you go into the battery info and tell us what percent the display is using?

http://www.tomshardware.com/reviews/ipad-3-benchmark-retina-display,3157-4.html <-- ipad 3 battery life isn't much better.
Sucks
Sorry, but I can run my S3 out in half that time playing a high end game.
Pushing those kind of pixels on a screen that size for 2.5 hours, plus another 2.5 hours of screen on is not bad going.
Further more, you can't possibly have had your N10 long enough yet to have properly charge cycled your battery 4 or 5 times, which builds its stamina.
I received mine at 11am yesterday, on factory charge (it was approx 60%), and playing with it most of the day yesterday, and for several hours last night (although admittedly no gaming) it only reached low battery (3%) when I woke up this morning.
The Display used 61%, need for speed used 21%
2.5h playing, full cpu, moving that amount of pixels, and 2.5h more, it's kinda good, man...
2,5 hours of gaming and 2,5 hours of web browsing? Thats useless for me..
I would say the A15 CPU ist more effiecient compared to previous tabs. Btw remember the high amount of pixel...so it is good
Sorry, misstyped.
It were only 1,5h of need for speed and 2,5h of surfing. So 4h in total!
The concern is that the N10 discharges while gaming even on the charger, why I didn't rush to buy one on first day. Best to always read true user reviews first before hitting the store.

It's don't really see that as an issue, I own plenty of devices that work like this, if anything its better for your battery, because first, it's slow charging, which is better for the battery, second, it's getting charged cycled even if it's always plugged in, which is good for its lifetime.

If they had used something other than a micro USB to charge it this would be fine. I saw a pogo charter in a thread but I'm sure it will cost $55++ which is stupid because it should have been standard with the device
4 hours of game/screen time is awful...I can easily get 8-9 out of my Asus infinity gaming/streaming/netflix while only taking 2-3 hours to fully charge. The slow I/o just kills that tablet for me though...

I had an iPad 3, and now have the Nexus 10. The battery life is a little better on the iPad, but not hugely so. That's with both devices at full brightness.
I can get 6-7 hours out of the Nexus and I was getting maybe 8 out of the iPad. Hardly a massive deal, especially considering this is a considerably lighter device with a bigger screen. Who has 6 hours a day to sit on their tablet anyway? I know if I did, I wouldn't have had to money to buy it in the first place!
As for charging: Yes, it's slow. It was also just as slow on my ipad. Am I missing something here? If you guys are seeing that as a deal-breaker, my advice is to stay well away from the iPad!
Ta,
Any tips and tricks when I get my device to help the battery? Aka a full night of charge out the box etc?

It's not that bad.
Mine was 60 out of the box, plugged into wall and came back 2 hours later it was fully fine
Swype'd at pace from my Galaxy S2
I think it's always a good idea to run the unit ONCE until it shuts off as soon as possible after getting it, just so you really know where zero is. It's not conditioning, just a way to help with calibration.
It's been my experience that new Android devices can run for many minutes after the battery meter was showing 0-1%. In one case it was over an hour (Tab 8.9).
Ok....I feel absolutely stupid and must be missing something but...how can I check the screen on time? It is just not listed under Battery as it is on the Xoom or the Galaxy Nexus for example
Click on the Display Entry in your Battery statstic!
Battery life usually improves after a few complete discharge/full recharge cycles.
What's the output on the bundled charger, 1A, 2A?
Anyhow, it's a trade-off. With the Nexus 10 you get the best screen and the most powerful tablet so I can live with the battery life. Plus, I'll be alternating between it and a Galaxy Note 10.1 as one charges.
