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 usage missing go here: http://forum.xda-developers.com/showthread.php?t=1424679
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....

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?
As well as the nook I also have an asus transformer and a bkackberry Playbook.
The Nook and the transformer seem to have similar standby time but I realised today that the Playbook knocks spots of of both of them. The playbook has been sat on the table in the living room for a good few days and it's been just in normal stanby with wifi still on (not sure if it shuts off when it sleeps). I picked it up expecting it to be flat only to find that it still had 30% power left!!! The nook just couldn’t do that length of time I'm sure, if I leave it it may last 2 days I guess.
What sort of standby time are you all getting? Do you set wifi to disconnect when it sleeps?
Woah, that's definitely NOT the standby time I get. I've set my Nook Tablet aside for a full day without use and the most I've seen it drop is 1-2% of its battery life. In fact, I haven't even charged it the past 1+ week and it's still around 70% (and that's with minor reading inbetween at low screen brightness and WIFI off).
I'm pretty sure I could set my Nook Tablet without touching it for a week straight and it'd still have a majority of its battery life like a champ.
The only thing I can possibly think of that's helping is my use of Juice Defender I have running in the background, but its main battery saving function usually involve s around minimizing WIFI activation as far as I can tell, and that is somewhat moot if I have it off.
yea I wish my NT could sit around not charging that long but really no complaints here. I get a good day out of it

Well from what little I know about the two tablets they both have the same base chipset and very similar screens so Nook 'should' be able to do the same as the Playbook so I'm definitely going to look into it further
well we need to find out what the secret is lol
I get days out of my NT when I don't use it, though even when I do use it I barely seem to put a dent in the battery percentage.
I'm so used to my old laptop and many phones over the years that I had to try my best to squeeze a day out of, that this thing just blows my mind sometimes.
My mom has a Transformer and she seems to have similar battery life to me, going on days without charging.

With my transformer it'sbecause eit dien'st sleep when connected to the dock, it's a known issue and if I got off my backside and contacted Asus they'd RMA the dock and fix it. If I disconnect the dock form the screen I get days out fo the screen even if I do use it a bit
Nook just doesn't seem to compare. Not yet anyway...
I'm on my fourth day, without a recharge. I haven't plugged it into anything since I started using ADBWireless. I can't estimate the screen-on time accurately, but I've read over 200 pages of memoranda and have been messing with my widgets and layout a fair amount. It's at 36% right now. I don't plan to plug it in until it dies (for science!).
anyone have any thoughts on this? I'm getting poor battery life as well. I'm running current widget and when I come out of idle there is quite a bit of current being drawn (200ma).
I'm rooted running go launcher.

I have been using my TP docked all day. woke up this morning at like 9 with 100 on both dock + tablet and have been watching anime since . It's 8 now and my dock is 0 and my tablet is about to die as well. I'm at about 40% brightness, I was expecting better battery life though.
Sent for my Transformed Transformer Prime :>
I get about 4-5 hours use from it doing simple tasks in low power mode.... 12 hours is a lie, if i use it on and off i can make it almost al day but that is with very minimal usage.
So i say u get about 5 hours low power mode and like 3-4 hours in normal mode ( nonstop usage).
jzen: I suggest you rma for that battery life, I have a lot of issues with the prime but battery is not one of them.

tf201no dock, 100% charge, 80% superips brightness. gps off bt off, wifi on.
playing shadowgun thd, and watching netflix lasts me about 7 to 8 hours (full usage as passenger, no breaks except 5 min bio stops etc) on my ride from reno to las vegas using my droidx hotspot for wifi net while playing shadowing thd in dead spots.

Here's my most recent battery report. Been using it for a little bit of everything, videos, music streaming, some games, other miscellaneous apps.
Sent from my Transformer Prime TF201 using xda premium
Tablet only
100% to 74%
2.5 hours
Wi-fi on, gps/sync/bluetooth off... eco-mode with backlight way down and streaming Internet radio (screen forced on whole time)
I ran mine pretty hard yesterday.
12.5 hours from 100% to 7%.
No dock, all tablet.
Watched some Dexter on Netflix, Recorded Video, used max brightness, power save, full power etc.
Surfed, Streamed, GTAIII, you name it. Used Bluetooth while streaming / gaming.
That is far more than i would ever do in a normal day.
Gotta say I am happy. My Tab 10.1 only lasted about 5-6 hours under similar load.
I guess if I averaged out each day with normal use I'm getting between 9 and 10hours in normal mode with the screen at 50 to 75% brightness. I do a lot of gaming and surfing. Since my Prime is new I'm still am doing a lot of customization. That will tail off a bit and I suspect my battery life should go up a bit. I have not rooted yet though. When I do charge it takes about 2 hours to go from under 10% to 100% on the wall charger and it turned off. I'm real happy with that.
Try this one on for size!!!
Here is my battery usage...though I will say that I am testing it for a battery spike usage so I did not use my prime at all during this time period...and you can see the issue I am having with the spike...but this is after a full charge with minimal use of just the browser from time to time....I am curious if anyone else is seeing this kind of battery spikes:
100%-29%
6 hours - at this rate I'd get roughly 8.5-9 hours out of a total charge
Tablet only, power save mode, screen forced on, low brightness, wifi on, bluetooth/gps off, streaming internet radio...
Tablet + Dock
100% tablet/100% dock to 7% tablet/0% dock
12 hours
listening to music, running TuneIn radio app in the background over wifi, screen forced on, lowest brightness.
bluetooth/sync/gps off.
Playing games, music playback, stream videos from desktop, youtube. prime only. About 7-8 hours on power saving/screen brightness 2 notch up from lowest.
Cheers!

Frequently, battery "spikes" are just where there's no data for a moment--in otherwords, if you reboot your Prime, during the reboot there's a gap in the battery recording data that then looks like a spike on the graph. It could be that.
Sure the prime can idle for 2 days or more but if your interested in actual batter life during use it is realistically about 6 hours of battery life on just the prime. The dock will help you to get another 4-6 hours.
Again, non-stop usage you will get around 6 hours battery life (gaming and netflix).

THERE is no denying the battery life on this device is Great. WAY better than my Ipad with same type of usage. PRIME was rated at the top of tablets in battery life. Only a lil bit behind ipad2 but more than ipad1. IT clearly has the best battery life of any android tablet out there. AMAZING considering its also the most powerful tablet out now also.

It kicks Chuck Norris' ass, straight up
12 hours of 100% screen on+wifi is a *tremendous* amount of battery life in a netbook-type form factor with the dock. There's only a few that could possibly come close, but not without sacrificing weight, size or horsepower or cost - $650 is simply amazing for this kind of device....especially now that Ubuntu has been formally chrooted onto it.
But usage styles, manufacturing defects, you name it, will influence battery life.
One guy reported only getting 4-5 hours of solid tablet-only battery life, which sounds like a manufacturing defect.
I'm also extremely interested in getting a baseline "real" number - sounds like 8-9hours is 'bout right for wifi/screen on 100%
Can't wait to start tweaking the hell out of it's software wise, underclocking, smart radio on-off.
I really believed ASUS' 18 hour battery life claim, however I'm curious what it's going to take in real life.
A lot of guys will overclock the Tegra3 for more performance - they're already doing that.
I'm the opposite - give me as little clock as possible and max out the battery life - I *really* geek out when I can eek out another hour

Well you know since we rooted already, you can use system tuner pro to manually lower the Max speed to increase battery life even more. It also has some presets n there which I think it has its own power savings mode also. It might even be better than Asus
Power savings mode. Haven't tried it out yet.
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.

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.
Please post bettery life and please specify the time of the screen on (in Battery settings).
My Prime works about 48 Hours. Screen on about 5 hours.
Screen Backlight about 50% during 2 hours and minimum during 3 hours.
1 Hourse I read. and 4 Hours internet with Google Chrome beta.
What browser eat more power?
i'm really sorry for this but:
hour = 60 minutes of time
horse = the thing you ride or eat
hourse = NO.
On topic: battery life is fine on mine. Really depending on what i do with it. I wrote an essay today with my prime. Constantly writing for 4h with screen on at half brightness, went down to 75%. If i was gaming the whole time it would be down to 30% or something i guess So it all depends on what you do. I think battery is great especially with the dock.
Sorry for my English)))
And what you thing about browser? What browser eat more power?
hm i never tested between browsers, i always use ICS+ browser as it has everything i expect from a browser.
I heard the new firefox is quite good though^^
I've actually been pretty disappointed in my Primes battery life. I had it in the second week that it was out, and I'd almost always get 10-11 hours out of it with the dock.
My usage scenario is usually, a lot of down time, very little video watching and a lot of web surfing/email use and I almost never play games. I've noticed more recently that my battery %'age drops by nearly 10% every half hour. I always have the dock on and if I'm lucky I get around 7-8 hours of use out of it.
Luckily I've never needed it that long in one go, so I've never really needed to carry that cheap quality charger that ASUS provides that's practically fallen apart, even after I took exceptional care of it.
The only saving grace I've had recently with the whole thing is Androwook 2.0; and it is just plain exceptional! No force closes and very very few freezes. Absolutely silky smooth. I was considering selling it before the new tablets came out but this ROM is seriously making me consider keeping this tablet.

Watching Video and Playing actually uses less power than Web Surfing, dont ask me why ^^.
The WiFi is a blackhole of power and eats the battery like theres no tomorrow.
I use my TP for golf GPS in my cart with the dongle, wifi tethered to my phone and the screen always on, brightest setting and I get about 5 hours (maybe a few minutes less) of use before it goes dead.
Wish there was a way to plug the TP in when using the GPS dongle.

True, but I hardly watch any video online at all. Like no Netflix or YouTube...
Infact even the pages I read are usually mostly text, hardly a couple images, and my brightness is in the lower quarter all the time. I usually just open a page and leave it open and use it as a reference while I type on my laptop, or writing or whatever...
It's a bit annoying when my Primes battery % declines at almost the same rate my as power hungry laptop's battery...
I don't think this is for the Prime or ICS:

Wonder if it's the same as Wipe Battery Stats on TWRP...

Does not matter what you are doing in internet as long as that WiFi is on, and transferring some data it will destroy the battery. Try it out without WiFi and see how long it lasts.
Regarding battery stats... it does nothing. Check this out, directly from Google: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
