I was wondering what kind of battery life people are getting. Playing games (some graphic intensive and some not), browsing web, etc I only get a little over 4 hours...its using about 20% battery juice per hour. Brightness was set to auto and power to balanced, but setting brightness a bit lower didn't seem to make much of a difference. My Motorola Xoom gets about 8 hours doing the same stuff using about 10% per hour. I am running HairyBean 2.2 since it seems to be most popular. Is there a rom that will get me better battery life? Since the TF201 is rated at 12 hours, I thought I would see similar battery life to the Xoom but its so much lower I don't know if I can give up my Xoom for it.

My battery life is a lot worse than before since I run HB 2.2 (when compared to 1.51). But then again, the tablet seems much more fluid and is a joy to operate. I guess you will have to choose between great performance and some extra 4.2 features and good battery life.
I get about the same...4 hours with the screen going nonstop if gaming, but probably more like 6 if it's just watching video.
For what its worth I've tried a few other CM-based ROMs and non have had the smoothness or battery life of the Hairy Bean ROMs.
Try to remember that the super ips button is missing from 2.2 so is enabled all the time.
That's all super ips does is up the brightness so if you are running with the screen on full brightness that is the equivalent of having super ips on and full brightness before.
I never use auto brightness and very rarely is my slider over a third of the way up.
I also set disconnect network when sleeping to always in asus settings.
These are the biggest 2 causes of battery drain and running the screen with the slider on full is just asking to flatten the battery.
Try going back to 4.1.1 and turning brightness up full and switching super ips on and see how long you last
My battery lasts forever.
Thanks all. I will try HB1.51 and see if any difference in battery life.

I would agree that setting the Wifi to disconnect when sleeping completely changed my battery life.
I am not sure Super IPS is the same as only increased brightness, I think it also changed the screen refresh rate (saw this in a few youtube videos where it was in sync with the video camera like an old CRT TV with Super IPS off, then disappeared when turned on).

It is just brightness.
I just use my Prime for studying because my books are in it, I usually spend 8 days until my battery dies (I´m running stock rooted).
I got about 4-5 hours on stock V10.4.2.18 JB with WiFi on and lowest brightness (Internet Surfing)
I think the battery life got weaker than one year ago..

Stock ROM - Locked, rooted and tweaked.
Battery life is 8 to 10 hours depending on what I'm doing. I always have brightness turned all the way up but only use SuperIPS when I outside. I have WiFi turn off when it sleeps.
I surf, check e-mail, play music and games (DH4 right now which is graphic intensive).
Thats the Prime only. I can get 16 hours with my dock.

Now look what you have made me do, you have made me post from holidays lol.
In Standard IPS mode, the Transformer Prime maxes out at 380 nits, but when you enable Super IPS+ mode, that number jumps to 600 nits.
I also have the code in front of me that controls brightness and super IPS and I have never seen an increase in contrast anywhere in it.
Please show me the source of your info.

What gives you better battery life - keeping it on Auto or setting it manually to a lower setting?
People say auto brightness affects battery life because it utilizes CPU power. I call shenanigans on that though because it will use very little CPU power... I vote AUTO.. cause if your out in the sun and your settings are set to low... You are just going to tweak them to accommodate your needs.

I have mine set on auto, but it doesnt dim or brighten up.
Bet it does! just when it needs to brighten and dim, you never notice. I thought the same thing until I played with it for a while thenI noticed it working.
auto eats more power, but it does what it needs to.

It uses more power to make the display brighter. Think of it like those 3-way light bulbs. The lowest setting is like 25 watts, the middle 50 watts and the brightest is 100 watts.
There is a widget that lets you change it manually between 33, 67, and 100% brightness with the touch of the button. I have that on my 2nd screen (along with WiFi, GPS, etc) and keep it at 33% most of the day every day.
I use auto due to ease and I easily get through the day without charging. I do use manual if I am in a dark room b/c auto just doesn't seem to dim the screen enough.
I like the 3 setting Brightness widget also. I like to set it where I prefer, didn't really care for auto. Don't know about battery savings with either one.
Is this a stock brightness widget or do I have to get it in the market?
I keep mine low...
24 hours later... 55% battery.
I use battery level its a small widget to change every 25% its great my battery is amazing Im at 58% after 12 hrs using 25% the brightness level and of course WiFi always on and turn in mobile network when I leave the house which saves me SO much battery
Sent from my PG86100 using XDA App
I always run mine at 100% brightness. I don't care about battery life. I prefer a bright screen.
Using a widget is probably no bad but I just auto , come on the phone was made with the sensor for it and it doesn't use much battery unless you have it a t 40% or lower all day long and struggle in the sun. I been using in auto since the iPhone I changed it for Android but i went back to auto cause it waste time just to change the setting everytime and annoying too

It's a stock HTC Widget, but they also put powerpanel in there. I just think the HTC widgets look nicer.
I wished the auto brightness function had user-defined options. I agree with it being way too bright at night.
I have been using the 3 setting brightness widget/button. Usually always leave it on medium till I'm at home with the wall charger then I use max brightness.

The best widget I've tried is Brightness Level made by Curvefish. You get easy access to preset levels, a slider to adjust brightness to any level, and enable or disable auto brightness.

it would be nice to find a widget that sets a daytime and nighttime level. i use tasker but i think it's just too big of a program for just this one little thing.
I shut off my auto brightness off yesterday after a few hours to see if it made a difference and set my level to 40%. I don't know if it was a fluke or not but after 13 hours when I plugged my phone back in to go to bed, I was at 63%.
That is a huge difference from what I have been seeing. I am going to see how it turns out today with the same setting but I must say it is looking pretty good so far. After 2.5 hours with some texts, a little web surfing, some theme changes and emails and I am at 93%.
I will post back my results later tonight. I am also using power control plus which has a brighness widget that you can set to a percentage for each hit. So in case I need fill brighness, one click and I am there. Another click I am back to 40%.

Im getting 115-142mA with the phone idling with the display on with wifi on.
With data enabled/wifi off it jumps to over 200mA.
Having Bluetooth on but not paired didnt seem to make any difference in battery consumption.
Having GPS on but not in use also showed no increase in battery consumption. However, having gps in use (had navigation running in background) caused the battery to spike to almost 400 before settling around the low/mid 200mA range.

If I turn data/wifi/gps off and put brightness to somewhere between 30-40% approximately it sits between 91-98mA. My original posts were made with auto brightness on.
And its no bother. Takes seconds to adjust settings and I just left the phone sit for 5mins with display on.

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.

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.

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

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?
Hey guys i tried looking through for a bit and didnt find much on this...how is your TFP`s battery life? I`M not too happy to be honest, for instance today my battery is at 20% been on for 6 1/2 hours and havnt really done anything too intensive, mostly just web browsing and downloading apps, played a game for about 5 minutes.

It really depends on your setting, or how you use it... but saying that..
it isn't as "good" as Asus advertised, nor some other media/blogs have reported from their "hurried" interviews.
ICS update probably has something to do as well... I really don't think Asus and Nvidia has fully worked out Tegra 3 with ICS yet.
I think in normal use the processor is kept at too high a frequency. I rebooted about an hour ago, and since then mine has spent well over half the time at 1200MHz. Given what I've been doing, that seems like overkill. I think ASUS is still tweaking the power profiles, which might account for the apparent variation between revisions.

I've been satisfied with battery life, not that I've timed it.
Sent from my Transformer Prime TF201 using Tapatalk
I've timed it several times. Its your settings. I get longer than what you posted on my 1.6Ghz vipercontrol overclock. Stock settings easily get 9 or more hours. I always have my brightness low as its bright enough. Having it at 50% or more is a waste unless you outside LR have bad vision. At night I know you can't be having brightness up like that or you'll hurt your eyes looking St that bright screen. DISPLAY BRIGHTNESS is the biggest drainer of battery. Along with web surfing, watching flash videos, or streaming movies. If you doing all that, maybe use power savings mode instead. You can still surf web n all that with no problems plus battery will last even longer.
For me, my prime easily gets Asus advertised battery life n more sometimes. If I can run a 1.6Ghz overclock n get better than what y'all posted then you need to adjust your settings.
As with all battery life situations on Android, make sure you pay attention to the following:
Screen timeout, make sure the screen does not stay on for long when you are not using the device.
Look at your applications that schedule background tasks and auto synchronizations as well as the sync settings in your Accounts & Sync. Don't sync data that does not need to be sync'ed.
Use the balanced performance mode most of the time.
Turn off features that you do not need, such as GPS or bluetooth, if you are not using them.
Under developer options turn off 'animation scale' settings. This will make moving around menus more snappy since there's no transition time and it also saves a little bit processing power if you move around in Android menus a lot.
If you do not use WiFi, keep it off or at least turn off available network notifications so it would not constantly search for them.

On ICS it should be done by GPU, so I think it will affect battery life very, very little.
My concern is more about the keyboard/dock battery life.
It seems to drain a lot faster than the tablet and it never stays long at 100% ; always fall to 99 or 98% although the tablet is not under 90% yet.
I wonder if this is because I first charged the dock alone instead of charging it with the tablet on it.
Anybody sharing these feelings with me ?
I would say the reason is that dock always charges the tablet. I've also notified that dock's battery is empty in the morning if I left tablet and dock together during a night.

Please use search, the 98%-99% thing has been discussed and asked over and over again for ages. Your battery never stays at 100%, neither the tablet or the dock.
Once battery reaches 100%, it stops being charged, otherwise it can damage the battery.
Dock battery discharges quicker because the dock battery is smaller than the tablet battery. The dock does not 'double' the battery life.
As of TF201 (differently from original TF101), dock starts charging the tablet once tablet falls near 70%. This makes sure that battery on the tablet (and dock) are used more efficiently and lasts longer (it goes through less cycles in the end). While this means that dock does not keep tablet at 100% all the time (so you can remove the tablet at 100% always), it does mean that battery life will not diminish as quick as before and you're prone to less hardware problems in battery in the long run.

I wish, I am at 3% and 7hrs 20m ...this really isnt good at all, brightness is at 50% ..any suggestions? I feel like i should be getting another 2 hours out of this.

The 50% brightness is most likely why you are seeing lower than expected battery life. Also, you should be in power saving mode if you are wanting to extend the battery as long as possible.
ASUS claims the Prime's battery lasts 12 hours using the following criteria: "Battery life tested under power saving mode, playing 720p video playback, Brightness:60nits, default volume with headphones."

Not sure what 60nits corresponds to on the brightness selector but I am assuming it is low.

Yeah , 60 nits is very low, especially since prime Max brightness is significantly way higher than that. Like 380 nits(unit of measurement for brightness) or more. BRIGHTEST tablet/display on the market today.
After posting last night I messed with YouTube and browsed for about an hour and only lost about 5% or so. Seems good to me.

Please use search, the 98%-99% thing has been discussed and asked over and over again for ages. Your battery never stays at 100%, neither the tablet or the dock.
Once battery reaches 100%, it stops being charged, otherwise it can damage the battery.
Dock battery discharges quicker because the dock battery is smaller than the tablet battery. The dock does not 'double' the battery life.

Sorry, I red and searched a lot already in this forum but I missed that.
Just didn't think there was such a gap between a 22Wh battery and a 25Wh one. Thank you for your answer.

I've noticed on both the Prime and my original Transformer that the dock battery does seem to discharge more quickly than expected when charging the Prime. It's not directly proportionate, I don't think, i.e., 22Wh is about 10% less than 25Wh, but I don't think the dock only discharges 10% faster when charging the Prime.
I think there's something about the charging process that makes it less efficient than simply powering the unit. Perhaps some power experts can chime in here and explain it... Certainly, I've noticed that charging the Prime from 70% to 100% can just about completely discharge the dock.
I've noticed the dock discharging faster if it's plugged into my usb port in my PC. I think the media mount takes more power than I thought it would.
When not connected to my PC through usb, the battery life is pretty long when doing regular web browsing and video watching.
Playing games obviously causes the battery to drain faster. Also the brightness also has a large affect on my overall battery life.
As others have said, turning off wifi when you're not using it will massively extend the battery life.
The screen dims and changes brightness by itself so much I am contemplating just turning it up and leaving it.
Any thoughts to this, and does it drain your battery super quick?
Seems a waste of the SLCD 2 to have so dim and changing brightness all the time

If you plan on disabling brightness just keep in mind if your an outdoors user or indoors user, the lighting around you will play a key roll on what levels of lighting you decide to have.
Personally I have the Automatic setting enabled, but I keep a widget (via widgetsoid) handy so I can disable it when I want and how I want on the fly.

Max brightness will definitely have an adverse effect on batt life. I personally keep mine at about 40% which is fine except when im in direct sunlight.

I know what you mean, I tried doing the same because I got sick of the brightness changes all the time, but after a couple of days having to adjust it myself or compromise on batt life, I decided to go back to Automatic settings... In my life I go to much outdoors as I can spend hole days indoors its what ever happens, happens so I decided to stick with the annoying setting other than being annoyed by having to set it myself.
Screen brightness is the biggest contributor to battery drain. I keep mine as dim as possible at all times. I've unfortunately become quite OCD about it.

I'm the same way. But the problem I have with this phone is that the more dimmer I make it, the more uglier the whites become (which I have become OCD about).
So I have double OCD working against each other and my brain is going to explode. That is all. Carry on.
Ok; the phone has been out a few months. Anyone's opinions changed?
I generally keep screen auto-brightness OFF, and set it to about 60% to 70% brightness static. When plugged into power to watch video, I go to 100%.

+1 for Auto and a widget. Most of my use happens at the extremes - OFF or 100%, so this provides easy switching.
I keep mine down around 10%, and only use autobrightness when outdoors
