I have been able to get 6 hours and 40 minutes of display time before the battery shuts off. I was watching back to back Seinfeld Episodes on Moboplayer.
When I first got my phone I installed some emulators, and started playing Pokemon (never played back when it was popular). I got 4 hours of display on straight one Saturday afternoon while playing Pokemon Sapphire. I was astonished to see that I still had more than 50% battery left when I closed the emulator.

display-on time is the thing i always look for in a device and try to get better each time. if you read the anandtech review of the atrix, they got like 8 hours of web browsing time which was the top dog except the iphone 4 being higher (at 11 hours).
They must have had a magical iPhone 4 then. I have had 2 iPhone 4's and never got the battery life I have with the Atrix. Plus, I never used "background data" on the iPhone but I do on the Atrix. Regardless, I don't use phones for videos or games or anything like that (never did) but I have had my Atrix over 70 hours off a single charge with almost 3 hours of display time if that's any consolation.

My highest was 2 days ago.. 7 hours display time on a little over 24 hours. This was after following the instructions in the battery life thread that have you pull the battery after its charged to 100%, then reinsert it when the missing battery icon displays. I let it charge for an extra 2 hours after doing this and battery calibration now shows 4203mV at 100% charge..my battery life is now amazing.

Are you using any extra applications to save battery? SetCPU? JuiceDefender?
Last night I reached 2 hours of display time with 72% battery left. All wifi web browsing.
Hi Guys
For those people thinking of getting the Flyer here's an example of some real life battery usage results.
I've got a BestBuy WIfI only Flyer and I'm running Paul O'Brien's HoneyComb 3.41.405.1 rom.
Without doing anything special (E.g. turning services off etc) I managed to get over 8 hours constant usage with the vast bulk of that time spent streaming videos from you tube.
I've been running the Flyer ON-STOP since full charge and I've got 8% battery left. For 6 1/2 of those hours I've been watching YouTube videos (Just left it playing through my playlists) so it's been using WiFi for at least that long out of the 8 hours.
Regards
8hrs sounds about right. I use mine for work & it last from 8am to about 4pm, using WiFi or 3G, streaming radio, or playing music. Surfing the net, emails, working on documents etc. The display is the biggest user of battery life. So if you give it a break & leave it in sleep mode for a few hours, it will last longer.
After some searching, I can't find a thread dedicated to *just* battery life reports.
Lots of discussion and long rants/stories/theories/anecdotes/etc/etc.
Please answer just the facts:
Just TF201 Tablet or TF201 Tablet & Dock
From what to what including Dock values if applicable
Example: 100% (tablet/dock combined) to 15%tablet/30% dock, etc. etc.
How long: number of hours ran

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.
robomo:
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.
rooted ics, stock cpu frequency no special tricks.
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).

I can constantly get 8 hours non stop usage out of mine with about 7-10% remaining.....just because something happens to you that doesn't mean we are all wrong or lying..at some point you need to realize the common denominator is you

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.

Wow.
With the screen on?
Could you possibly take a screenshot of the battery statistics?
I would really appreciate it so i could have something to compare to.
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?

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.
I decided to run my own battery test this morning. I created a 720p video copy from my Cars blu-ray. Copied to my Evo LTE, and started playing it on MX video player. It will play the movie over and over until I stop it. I'm trying to simulate watching video on a long flight, so I put it into airplane mode. Brightness is set to auto.
So far, the video has been playing 3 hours and 25 minutes. My battery is showing 66% remaining. So far so good. If the battery percentage is accurate, I should get 9+ hours out of this, possibly 10. I'll keep it running and see how long it goes.

Awesome! Can't wait for your results.

It's been playing for 6 hours now and the battery has 40% left. The phones seems to use about 10% per hour. Let's see if it will get up to 10 hours.
So far, I'm very impressed. My old Evo didn't last long at all playing videos during my plane flights.
Oh, and I forgot to mention, the 720p video looks amazing!!!!
Mark
Ok, so I stopped the video when my phone hit 10% battery life. The phone continued to use approximately 10% of the battery life per hour. So the final play time was 9 hours and 8 minutes. It would be very close to 10 hours if I kept going. Excellent battery life if you ask me!
(the screen shot was taken after plugging the phone in to start charging her back up. that's why you see 11% and the charging icon)

Not to shabby. It can only get better with some custom ROMs & Kernels, to maximize battery life.

Really? He gets ten hours out of a mobile phone playing 720p video and all you got is "Not too shabby"? When my Galaxy Tab was new I did a test with a video at native resolution in airplane mode and got like 5 hours of video. Considering the size of both batteries, I'd say ten hours is fricken bloody phenomenal.
As a different comparison of usage, I played about 3.5 hours of video over wi-fi on my LTE on Friday. The first half hour was through the flash player, and the latter 3 hours via the twitch.tv app. I did also have it off the charger for like 9 hours entirely and made a short phone call too. Not only is the battery on the LTE amazing, the frugalness of the hardware in using it is also.

lol. +1. This is so true and funny
Here are the video details if anyone is curious. I'm not sure if things like bit rate affect battery life.
just for comparison.
i did a similar test with my OG Evo, 4 hours it would play movies then it shut off at 0%
OP, your results are impressive. Can you post more information? I'd like to know about the audio stream. And also at what speaker volume were you playing the movie?
