Hi all, I am looking for a battery widget and/or app that will let me see how long my battery will last. I used to have something like this on my OG Droid and it learned how I used my phone. At first it was really bad but after a few days it learned and was really good at telling me how much time I had left. I haven't been able to find anything like it since that app. This was also back when then OG Droid was still on Eclair... Any help is greatly appreciated.

true. what I usually go by, in found to be true, is in balanced mode, battery drains about 10% or a lil less per hour with heavy usage. light usage, drains even less. battery savings mode, drains even less. Normal/full power mode, will drain a lil faster than balanced with heavy usage. I've pulled about 10-11% percent drain on Normal before. no matter whatnode you in, how much it drains is directly affected by what exactly you're doing and screen brightness level.
ill see if i can find a good one for what you all looking for though. I had some good apps like that on my Ipad.

Usually drain 10% an hour but this morning I played an hour of shadowgun, hour of riptide and downloaded over 5 Games and tested them all out so I drained 35 percent in 2 hours in normal mode

In the teardown the capacity is shown as 25Wh, or 3380mAh. Hope that helped
If you do not have system tuner and battery monitor pro both by 3c from xda then you have no real info about what your transformer/prime is doing. IMHO.
the MAH is 3300 and I think 3380 for the prime. He also has a specific version of this for the transformer which takes into account the separate batteries when docked. I have been using them for a year. It will tell you the average estimate from use, the average estimate from current use, or the actual estimate from current use, and it will reset your battery stats file if rooted.
edit forgot. the system monitor will show what each cpu is doing, 2 for the OG and 4 for the prime

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.
Sent from my Transformer Prime TF201 using xda premium
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.

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?
Anybody else notice that standby battery life seems to have gotten worse in 8.8.3.33? Mine was dropping less than .5% per hour before, now it seems to be considerably more (just noticed so no chance yet to quantify)...
Edit: Actually, I'm leaning toward battery life in general being worse...

Hard to say but I'm leaning towards maybe lol
I agree it could be a maybe.
Mine was fully charged when I disconnected it before work. It's been sitting at home on standby for 15.5 hours and it's at 94%.
During that time it's been connected to my WIFI, it updated google translate, and it synced with 3 e-mail accounts every 4 hours and my main email account every hour.
Seems the same to me.
mines seem to get even better battery life after update. check your background processes to make sure they aren't any unwanted background apps running. those will drain battery. overall battery life is great and the standby life is unreal how good it is. do you think your battery fully broken in yet? how long you had it?
Mine seems worse as well. No testing to prove it but it's been in the back of my mind since shortly after the update.

Nothing new since the update as far as background processes. I've had it since Friday, and it's had two full charge/discharge cycles. But again this is compared to before the update...

Mine goes down 15% per hour - mainly browsing www. isnt it to much? Before and after uptdate
i had 99% a hour ago and now its 90% i have only watched 10minutes of iplayer and read one email the rest of the time the tablet has been on stand by. i have a task killer running and it was up dated yesterday.
also i cant seem to see Time remaining of the battery rather than just %
its as bad as my HTC HD before it was rooted
As an update, I let it sit overnight for 8 hours and it went from 15% to 12%, or about .375%/hour. So, that's pretty good standby performance and my impression was mistaken.
After using it, though, I'm thinking my impression was coming more from battery life in use, which does seem less than before. I think they've done something with the power settings that I'd expect them to undo in the next update (or just in the ICS upgrade).
The power mode you using, type of activities you doing on prime, and brightness will directly affect battery drain while device being used. I always have my prime in balanced mode for the best of both worlds, Performance and battery life. as i never had any lag or any anything in this mode. I've noticed, even with heavy usage in balanced mode, battery drains about 10% or a lil less per hour. if light usage then it even drains less. Check out my "Different Performance Modes of Prime/Tegra3" thread. I started it to address issues like this and people compare performance and battery life in different modes. as everyone will have a different setup or use different. There is also a bstterylife thread started by TylerZ that needs resurrecting also. now that all the preorder threads n such got merged we can have some more relevant threads stay current.
honestly though, the battery life is amazing on this tab. to the other guy saying he has a task killer rubbing in the background..lmao that's his problem right there. Honeycomb or ICS doesn't need task killers as memory managemanent is already taken care of by the OS itself. and does a pretty damn good job at it also. if you wanna kill one or 2 apps that's OK. but to have a task killer running in background of honey comb OS does more harm than good.

i've noticed a slight downgrade in battery life while using the tablet, but not in standby mode.
also noticed that changing the performance mode no longer seems to make as big of an adjustment to the screen as it used to. perhaps the update increased processor performance, which explains why it feels snappier in general, and also seems to use up slightly more power.
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. My touchpad seemed to get similar if not better battery life... anyone notice this too?

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.

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.

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."
http://usa.asus.com/Eee/Eee_Pad/Eee_Pad_Transformer_Prime_TF201/#specifications
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.

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.

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.
What's the longest anyone has managed to stretch their battery life while actually using their Transformer Prime?
I seem to get 2-3 days with average use, some light gaming, etc. but I did manage almost 4 days once:
Well due to my noobness here I can't post a proper link to a large screenshot, but it was 3d, 16h, 46m, 2s at the time of the screenshot.

PM me a link and I will post it if you want.
Not too long for me, only a day and a half or so. Then again, I use this thing a LOT.
I stretched mine about an inch before it died...
>:3
Come on now, everyone knows the battery in Prime "LUVS YOU LONG TIMEEEEEE!"

Thanks for the offer, it let me fix the link myself since I made a few more posts tonight.
I have managed to run it out in half a day before with heavy use, so I know it can be a hog when it wants to. Overall I've been pleased with the battery life I've managed to get from it thus far. Only once have I found myself in a position where I wanted to keep using it but the battery was low. Every other time I've been plugging it into the charger just to top it off in case I need it more the next day.

Obviously very dependant on use.
This screenshot shows my typical use i.e. undocked, wifi on 24/7, in sleep mode a lot, but awakened every few hours for a bit of browsing etc.
One thing that did occur to me was the small battery loss when using tapatalk a lot. This is presumably because I have the display with black background and white lettering. Wouldn't it be good if there was a web browser that allowed the same ? or is there ?

On standby, mine lost 56% in 16 days during an RMA.
Wow, pretty jealous of you guys and wonder if I have a battery problem.
I get about 2-3 days if I use the tablet for about 2 1/2 to 3 hours a day. Is this normal?
I didn't do the full charge out of the box as recommended though...
Would say it is normal. With Wifi on, all sensors on, Balanced mode, auto brightness on (mostly around medium brightness), normal ips mode mostly brwosing the web and playing I get around 6-7 h continuous screen on time. Measured with better battery stats. I think this is quite good. Everything without dock.
Wow...my battery life blows. I've been on it constantly surfing online for almost 2 hours and I'm down to 72%. My battery just drains so quickly when online on 25% brightness. I'm only syncing gmail.
Just had to post this factoid. I've had the DNA for about 2 weeks and i honestly can't believe the battery life. It is just getting sick battery life. I've had alot of smartphones over the years, but this one is by far the best in battery life. My last phone, droid razr, was on juice defender and barely made it through a day without charging and minimal use.
An example day like yesterday is typical:
unplugged at 7am fully charged. Bluetooth streaming music for an hour ride to work, 4 hours of music streaming during work along with 30 min of gaming (lunch). Streaming music all the way back home - 74% At home, 1 hour of tasker, 30 mins of various email and facebook. Result - 59%. No charging overnight, on it's 7am alarm, it is at 53%.
It will go 2 full days of use without charging. How did they do that? The battery is barely bigger than my dual core RAZR on a much smaller more efficient 4'3" screen. I've always had SuperAmoled phones like the galaxy S3, RAZR, etc.. I thought superamoled was more efficient.
I saw the XDA review a couple days ago and another online review a month ago. In both cases, the reviewers were also a bit perplexed about the great battery life. It wasn't just good, it was unusually GREAT.
That's good to hear.. mind to post some screen shots? Particularly the screen on time.
If I didn't live in a signal black hole I would easily get 2 days out of mine...

The RAZR's battery life was so bad, I remember those days :crying:

What's a good app to show this breakdown?
I agree 100% Compared to my thunderbolt (had it until a few weeks back, was almost 2 years old) which could not really make it through the entire day with regular usage, the DNA usually ends up at around 50% (at least from looking at the battery symbol, I've not bothered to look at the actual percent) with regular usage. I live a few miles away from a tower, so not sure if that affects battery life significantly, definitely works well though. Combined with the wireless charging setup (was not planning on getting it initially, but had ended up selling back the thunderbolt + had some sort of work discount, so it had ended up only being around $11) battery life is the least of my concerns at the moment
I feel the same way. I had a TB with rezound battery and SoaB 1.4 and it drained so fast. My DNA seems to last forever. It's such a relief to not have to have a charger around if I'm going to be gone for more than 6 hours.

Any thoughts as to why it gets so amazing battery life? On paper a quad core 5" screen with just a 2020mh battery should barely make it through the day. The nexus 4 surely doesn't get this life on a similar chip with smaller screen (i have one).

The screen is super efficient, the processor is super efficient, and sense is pretty good with standby.

I concur. I charge my DNA every other day. I've only had the battery completely drain once before getting it to a charger.

Same here with the battery. I have been really impressed by the battery. Before I got the phone all I heard was bad about it.

I totally agree with the above comments. I was scared by the prerelease estimates of the battery. Using it daily has proven the opposite. Some times I look at my phone at the end of the day and worry about the battery not fully cycling. There is to much charge left to start charging. Hopefully new batteries don't have that issue. In addition these awesome developers truly maximize the capabilities of this device. And they never seem to quit.

So what are you guys doing to get the battery to last so long? I think I have pretty good battery maintenance, and I get almost one day out of it with minimal use.
I did just get the device a couple days ago so maybe the battery hasn't been conditioned yet?

What's your screen on time like. Because one person's definition of minimal may not be the same as another person's definition of it.

I know my screen on time is really low. I teach so really do not use my phone more than 1 hour of screen on time between 7:00 am - 3:00 pm. Image below:
View attachment 1856496l
However after that my usage really picks up. My phone still lasts until 9:00-10:00 without fail. Thanks to the amazing development group dedicating so much effort into this phone I have seen improvements in charge speed. I will post my before bed power screen tonight for comparison of usage and full day performance assessment.

Your app usage seems really high.
Sent from my HTC6435LVW using xda app-developers app
Check battery usage at the end of the day and disable any apps running services you're not using. Mine was using Maps a lot for some reason so I disabled it in Titanium. There were a few other apps with notifications that I turned off as well and now I'm still at around 70% around 11PM after being off the charger since 8AM with moderate usage.
Just installed GSAM yesterday.
Ran the phone a little harder than normal, I use juice defender, but set it to FORCE ENABLE data, which offsets it's use. To give an example, typically on Juice defender on idle, it uses about 1% an hour. So overnight, i would expect less than 8% drop, but these last few days, it was more like 15%.
Had the phone on for 34 hours on battery and it still at 24% battery. (just plugged it in to get the screenshots).
