I keep hearing some people claim how "great" their Vibrant's battery is. I am on my third Vibrant and battery life has been terrible on all of them. Just recently I noticed ~16% of my battery got drained for ~15 minute voice call. (The attached screenshot shows voice call using 27% but at that time my battery was at around 39%, which means the 15 mins took about ~16% total battery.) I just passed my 14-days buyer's remorse, so exchanging it (unless I want a "like new" one) or returning it are not an option. Any suggestions on how to improve battery life? I already keep the brightness on the screen to the lowest it gets.
Thanks!
Hmm that defintely is not normal. I would check with the store in getting another replacement. 15% drain on 15 min call is not normal for any phone.
There is a bug where if you power down the phone while it's charging, then the reported battery % is higher than actual. Perhaps the seemingly fast drain is a result of the reported value "catching up" to the actual level.
Edit: So I figured out where you're getting your numbers .
Still doesn't seem right though, did you notice the battery percentage before the call by any chance?

My rooted G1 had that same bug. Start charging it, power it down, power up and from completely dead it would show around. 24% in a couple minutes of charging. This phone I've noticed does it as well as newer blackberry's. Bizarre...
What I would suggest is draining the battery till it dies, charge it back up fully and see if you can have it happen again. Could've been a fluke.

looks like a bad battery reading to me.
Complete charge, complete discharge, and complete charge should reset it.
Yeah the percentages do need to be calibrated and sometimes they are off a bit, say 100%-90% actually often goes faster than 80%-70%.
The batteries are also partly responsible since discharge Ah is not a completely linear relationship with voltage (which is why the percentages need calibration).
I would say unless you have a rogue application on your phone eating battery it is more likely just how it is being reported.

So if battery A has x% greater mAh than battery B it does not mean A has x% greater battery life?

I'm having same issue. Battery life on my Vibrant is just horrible. I can barely go half a day until it's fully discharged and that's about 30 min talk time an hr maybe browsing apps and internet and a little WIFI/BT. Just for example I charged it after complete discharge and took it out at 11.30 pm last night, drove my brother to the airport and back around 1.30 and while it was sitting in the car and a few calls I made, it already went down to 74%, I purposely left it without charge till morning.... at 8am it was showing 47%... WTF!!
I have rooted the phone with update.zip, I have installed ATK and have Crazy settings on it.... one thing I don't get is that after it kills apps, they keep coming back every few seconds. Also brightness is at the lowest and no live wallpaper...
UltimateJuice by the way is showing 1.58 times, which is BS... right now it's 10.30AM and its down to 38%....
Any help would be appreciated!
Try not using atk

Vibrant's battery life does suck, even with the supposedly power efficient processor and super amoled!!!!!!
Samsung has some more work to do. Hopefully, the froyo update can alleviate the problem!!!

Read this first.

Anytime the screen is on its eating battery. We have the best screen in the market. If you really want a conservative wallpaper use something almost all black or solid black. When a AMOLED screen is displaying black the LEDs are off.
For those "apps that keep showing up" those are due services that are running in the background. If you don't use the app often set the notifications to a lower time or set it to update manually.
If you've rooted there is a thread on "how to keep your phone quick and snappy" read it. Also fix your permissions through recovery. Rogue apps apps can drain battery.
after 3hrs of on & off hard using (minus extra long phone calls >45mins) I can pull 12-16 hours easily on one charge.
Look into things like eugenes vibrant 6 & JACs UV(under volted) kernel.
GL and car chargers are awesome!

Battery life on my Vibrant has been superb. You might need to change settings or something. This screen shot was for today with lots of calls and market shopping and I even watched a movie. I do not use a killer, yes I'm rooted with lots of tweaks to my notification bar. I'm using the spiritbomb lwp and its been great.

Unfortunately, the battery life on the Vibrant just sucks, compared to the iPhone.
I came to a Galaxy S and a Vibrant form the iPhone 3Gs.
With the same style of usage, the iPhone lasts at least 40% longer than the Galaxy/Vibrant.
I like the phone a lot, but am really unhappy to have to constantly think about how I use it, to avoid it dying on me before the end of the day.
Basically, with moderate use, it will last for a day, but if I go out after work and do a little texting or take a few pictures, it will die before I get home.
12-14 hours is really not good, since with my old iPhone I used to be able to last almost two full days without recharging.
Plus, the blocking of the camera at 15% of battery life is a truly idiotic decision by Samsung.
Thanks for your feedback! I am newbie in the Android world, as I come from the Apple planet. It just takes time to get used to it.
As for XDA App, where can I get it?

I am looking into the mod for the notification bar, specifically the battery. I have seen a circle battery with percentage, where do I get one?
XDA is your Friend
Search XDA for all ur app and theme needs, as for the Iphone being better on battery. I dont doubt its better, but from my experience and many family and friends showing me there iphones they are always tethered to a power source. Theres no better test than driving 300+ miles a day every day and coming back to the hotel and seeing my phone tell me i have been using it for 20+ hours and i still have 25% charge. I am constantly using my phone for calls, text, movies and such. Without my phone my wife would probably divorce me lol The amount of travel i do via plane, train and automobile is all the real world facts i need. Vibrant is a keeper.
Yes it sucks.
And under 15% it's not allowing me taking pictures!
Come on, I know I am under 15%, but I still want to take 1 or 2 pic!!
Rather than clogging up other threads with my battery experiences, I thought I'd summarise where I'm at, and see how other people are doing with their battery life.
So I started yesterday on a full charge, and by 2ish the phone was dead. I used it fairly heavily, but wifi was off. I don't think I made any phone calls, and didn't use gps. It was mainly messaging and using the xda app. I had changed my screen brightness to auto the night before, so thought this might have reduced the battery life.
I then left the phone off, and charged through till just before 5pm. At this stage, the phone was up to between 90-100% charge. My intention was to see if I could get through to this afternoon on this charge. Last night I made a phone call for about half an hour, and used gps for about 10 mins driving in the car. Other than that it was a bit of messaging and browsing, but not heavy use by any stretch of the imagination. I had wifi off, facebook sync every 4 hours, and screen brightness set to about 50%.
This morning I woke to less than 10% charge on the battery, so have left the phone at home charging, and I'm back to my hero...at least for the morning.
I must admit, I'm starting to get concerned, because I really don't think I'm using this phone more than my Hero, and I could easily get a day out of it (unless I was going for a long run using some kind of gps app).
What are other people's experiences? I'm surprised I'm not hearing more about this, and I'm hoping mine is just a one off!
**UPDATE**
Today, 12 hours after taking my phone off charge, I have just under 20% charge remaining. The phone is now on it's fourth cycle, and although I haven't used the phone quite as heavily as yesterday, I have still used it quite a bit and have had WiFi on the whole time. This is still not amazing battery life, but it is still much improved. It definitely illustrates that the battery may take a few charge cycles before it optimises itself.
My first full day was yesterday.
WiFi on all the time. Screen brightness set to automatic. Twitter and facebook refreshing every hour. Weather every 4 hours.
Unplugged the phone at 7am, 100% charge.
During the morning I flashed the phone twice (due to the proximity sensor issue) so it probably recieved an extra 10 mins of charge.
Following the flashing, WiFi went straight back on so I could download all the apps again, and resync sense and all the contacts. There was some playing of games, some use of Google Goggles (so camera use there) and some web browsing.
By 13:00 I was down to 90% battery - which was pretty good I thought.
Through the afternoon I didn't get to use the phone much apart from a couple of short gaming sessions.
By 17:00 I was down to 80%. I got home from work and played around on the phone until my wife got home and we went out for a meal. The pub we were in had no signal, and I didn't really play around with the phone.
By the time I got home and went to bed, the phone was probably around 65% full.
So not a heavy day of use, but not far off a standard day for me - so not too bad as far as I'm concerned. Certainly about 30% better than my Touch Pro2 was!
I think we need to define a consistent way to measure battery life for Android.
Something like ACID test for web ... Quadrant for benchmark ...
I don't know, maybe we can agreed on something how to measure it. Or build an app to simulate phone usage which user should run it continuosly and then at the end got the result: Your battery life is rated 4 hours, 10 minutes straight using this test.
Probably not the best measurement, but it should give us a "number" to compare with other devices.
I can only suggest (I am not a developer), but I believe there are a lot of talented coders here in XDA which should be able to build this kind of "standard" app battery measurement pretty easily.
Somebody is recommending 3-4 full charges cycles for battery optimization. Do you think it will really help?
Battery is really deal breaking issue for me.
very helpful thread.
as mentioned few post earlier, there really should be a battery benchmark tool.
so was your wifi and/or 3g turned on the whole day?

My friends also lasted over a day with pretty good use, there seems to be better results with the brightness on auto...from what I have picked up on the forum...maybe a test is need to see how much difference there is between full brightness on one battery charge and auto on the other.
Yupe, the battery benchmark should not be so complicated.
Start the app with 100% Battery life
Some options in the app (for features that might NOT be in an Android phone or might not be available at the time?):
[ ] Turn on Wifi
[ ] Turn on GPS
[ ] Turn on Bluetooth
Set the app to WAKE all the time, display turned ON all the time of the test
Set Keyguard to OFF (device will not be locked)
Set Brightness to AUTO
Set all speakers to SILENT
Set vibration to OFF
Then loop until battery down to 5%, perform the below tasks in sequence:
* Play movie for 15 minutes [speaker muted]
* Browse to website??? be careful not to overload the website
* Doing arithmatic
* Doing 3D
* Play MP3 [speaker muted of course]
As soon as the battery down to 5%, app stop and display result ...
And of course restore all the settings.
The app should use generic API that is supported by Android, not some hacky wacky if you know what I meant.
Please if someone can code this, that would be very nice! Standard XDA Battery Measurement app for Android!

the app should log the result too.. since some phone is dead by time 5% due to calibration..
@Dazultra2000: I would almost trade the proximity sensor problem for the battery life you're getting!
In any case, I'm gonna leave my phone charging till half an hour after the green light comes on, then I'm gonna try another day of normal usage. I'm going to turn wifi back on, as I usually would, and set screen brightness to auto.
With my Hero I used to go for runs using a GPS app to log the route, I'm not going to bother trying that with this phone until I'm sure I can survive a day.

I don't know when you wake up but that could be like 14 - 15 hours that you mentioned which possibly isn't all that bad (plus the extra 10% you had remaining). Personally I want to see what it's like when you unplug it at 8am, not at 5pm the night before since I can't see any good reason not to leave the phone charging over night anyway.
If you then manage to get about 10 to 12 hours or so then there probably isn't much issue. Granted you weren't using it while asleep so the battery shouldn't drain overly quick but I wouldn't want to use your test as an example of a days use.
Thanks for the info but. If I was you I'd just have a car charger too if you like to use GPS...I can't see any reason not to.

Yeah, I would normally charge overnight, but since I had given a charge through to 5pm I wanted to see how it lasted....see if I could get through 24 hours. I wake up at 5am, so that was around 12 hours, with only 5-6 of those hours being time when I would've actually been using the phone. This is also bearing in mind that I had started yesterday on a full charge and the phone was dead by 2pm.
The GPS thing in the car was only to do a quick test, literally 10 mins. I need to buy a new car charger with micro USB, but I just made a note that I had done this because I knew it would affect the battery.
Anyway, we'll see what today brings.

Looking forward to it.
And yeah, for me personally a "days" charge really only needs to equate to about 12 - 14 hours. Thats probably the longest I'll go without having a charge anyway unless I'm camping or something in which case I'll likely fall back to a Nokia anyway.
Hi, just to add my experience with a complete different phone e.g. iPhone 3GS (developing apps on it, now switching to Android ):
Charge at night till 8 a.m. so 100% then usually in a day:
- Go to office, read/write emails, surf a bit on forums, blogs and so on
- Make call up to 30-60 minutes per day
- Play some games, test our application/games on it (so connect and receive some extra charge)
- Use WiFi at office
- Use Google Maps up to 15 minutes per day
- Back at home at 8 p.m.
- Use again emails and surf on web for 30 minutes
Around 11-12 p.m. it has less than 25% of battery, so 14-15 hours of usage drain battery up to finish it, not to mention that I'm forced to switch off push notification because they drain my battery in 5 hours!!!!
So just to say that, no one is perfect, and this devices today really do a lot of stuff, I think as Smigit suggest 12-14 hours are acceptable.
Have also tested/used iPhone 4, I don't seen any big improvements on that side.
Just my two cents...
praying for decent battery, please please please!
My HTC legend is pretty poor really, but I can live with it. If DHD is worse I don't think I can pull the trigger.
There is a thread in th Legend section about 1800mh HTC batteries (from another phone) that fit the Legend. Maybe there will be an option to do something similar with DHD.
I would pay £50 more for a 1500mh battery - why did they put the smallest battery in the largest screen?

No the battery doesnt fit with the Desire HD, if you watch some pictures of your 1800mah battery and than go and take a closer look at the DHD's battery, you will recognize that the pins of the DHD-battery are on its side. the pins from the Incredible Battery are on the bottom.
In 2 hours 30 min heavy heavy heavy use, the battery dropped 20%.
Will do a full day test 2 morrow.
Hi, I been having the HTC Surround for a little over a week now. I love the look and feel to it (I know OS wise it has a lot of improvements to do but I'm willing to put up with it for a bit, considering its a new OS). However one thing I notice is that it has horrible battery life! The phone last about 10/12 Hrs on a full charge. During this time period, there is no heavy use; tops 50 txt messages send and received, about an hour of music, screen lock (brightness set to low, when on), perhaps 15 minutes of talk time, data connection turn off, about 20 minutes of WiFi (I turn off WiFi when not in use), rest of the time on stand by as mention before (with the screen locked). Another thing i noticed yesterday night was that my phone was charge completely, i left it on stand by and within 5 hrs that i slept the phone had gone a little lower than 3/4ths (data connection was off).
I read a post here that said battery may drain quicker when phone is left in cold weather and i thought maybe this could be the case. However I'm really skeptical because i live in Los Angeles. Cold weather, which is this time of the year, is mid 40 degrees at its lowest! That's not cold! But anyways i guess I'll try putting that theory on a test (imma try keeping it warm, see if it makes a difference)
so is anyone else experiencing horrible battery life? Or am I just an unlucky person who got a defective battery?
THANKS in advance

What "theme" are you using?
If I don't use my phone, it will last for days. Even when I use it through out the day, it lasts well into the next morning/afternoon.
The battery life does get better the more you drain/charge it.

well, I been having it for a week now. I seen no difference in battery life. But imma give it another week or so. See if this works. Then I'm gonna try buying different battery. If that doesn't help, I think I'm going to have to switch back to my Samsung Captivate. I would hate doing this, but this type of battery life is a deal breaker. Today, it was even worse! It lasted me only 9hrs while I was at work, which at least 8 of those hrs it was on stand by!
Sounds like you have a bad battery, bro. I'd get it replaced at the store you bought it from.

yeah, I'm going to try this on my day off which is on Monday. Also gives me time to test out the other persons suggestion
thanks for your opinions. I'll get back to you guys and see what happens.
My surround - now two weeks old is showing much improved battery life. It didn't make it through a day when I first got it. Part of that was due to my fiddling with it and part due - I think - to the battery conditioning.
Now, it is going a full day on a charge. I am also switching off 3G and on WiFi when I am in my office or home. It is a bit of a pain in the butt and I hope that M$ gives up some APIs soon so that someone - cough Bruce Jackson cough - will write an app. We'll see.
I have noticed that the Bluetooth drains the battery considerably faster. Try turning Bluetooth off when you don't need it.

I don't use the Bluetooth at all. So this can't be the problem. but thanks anyways. (I might need this information since I was planing on using one in the near future).
So I notice that now, my Surround does get better battery life. (which is absolutely crazy! since now I have the screen brightness on medium and data turn on lol). I guess the battery just needed to be use and charge a bit more. However, I still think battery life could be improved. (hopefully, future updates will teak some system settings that will do this)
I have also decided that I will keep my Surround instead of going back to my Captivate I wish battery life would be better and the OS to be more "open" but truth be told, I fell in love with my phone haha Then when i went back to my Samsung Captivate, it felt weird. Android felt much slower.
So i gave it a little test; I launched messaging, email, music, browser, etc on both phones at the same time. Turns out both of them launch these native applications in the same amount of time.
I guess what makes WP7 fell smother and faster is the (eyecandy) transitions.
think its the battery
ya i have had mine for 2 weeks now and i think the problem is the fact that the battery is a 1230mAh, and we also have a samsung focus with a 1450mAh battery that will last an exra 2-3 hours longer which makes a huge difference! im hoping htc will make a larger mAh battery avaliable, mine will only last anywhere from 5-7 hours from normal use
I just ordered a Mugen 1300mah battery..not *much* more capacity, but hopefully it helps a bit!
if i dont use my surround (like not using too much 3g, wifi, music, gaming, and just normal phone calls and texts) it can last a whole day and probably a lil more, but when i do too much 3g/wifi/gaming/music it drains quickkkkkk.
and i do hope htc will have a larger capacity battery for the surround soon... 1230 is kinda small compare to other phones nowadays..
but still this has much better battery life than my previous phones (diamond2 and touchpro)
i just find myself carrying the usb cable and wall charger alot in my bag :]
and having a car charger is a plus also.
My girlfreind has had the phone since xmas. Initially the battery would lose its charge very quickly. I had her do a bump charge and just let the battery settle in. She can now go up a third day wothout the need for a charge with moderate txt.
Be aware the quick drop whenn taking it off the charger is NORMAL. Read this thread for a discussion of that http://forum.xda-developers.com/showthread.php?t=871051

Agree - Bad Battery Life - But not as bad as some....
Smart phones, in general, aren't what I would call great at conserving battery life under any condition. Pick any model of high-end smart phone and tell me who can get more than 2 days (using every trick in the book to eliminate unnecessary drain). Yes, this phone is under-powered in terms of only having a 1300 mAh battery when it should have a 1400 or 1500.
Cut the unnecessary stuff when you are not using it - Bluetooth, WiFi, etc.
You can easily get a day + out of this phone with moderate/mixed use (some talking, some browsing, some multi-media viewing). That's pretty good, I'd say (from my relative experience across many different types of smart phones). I just plug it in every night.....pick it up in the morning and go. Haven't had any issues with it running out during the day.
Now, if you are starting first thing in the morning and running movies, have the bluetooth going, the WiFi on........well, heck yes, you are going to have a battery drain problem. If you want to run it that way.....just leave it plugged in.
Has anyone used a Seidio Innocell 1300mAh Replacement battery? Was wondering if it was worth the investment to improve the Surround's poor battery performance.
Thanks,
So...when is someone gonna step up to the plate and improve battery technology? It really sucks that these phone manufacturers are giving us ALL these fancy features that drain the battery and when we complain about having poor battery life they are telling us to not use all those fancy features...kinda defeats the purpose of buying a smartphone, am I right?
guys .. wake PLZ UP ))
1 ghz (1-2 core cpu ) ..
3.8 and more screen ..
DEDICATED GRAPHICS .
OS .
with DIRECTX9 Interface .
and that all spiced up with 1600 ma battery in best case .
and that you wana to run more then 6 hours on full load ? say THX TO MS .. for NON multitask os .. overwise battery life was even more lol then this

My surround - now two weeks old is showing much improved battery life. It didn't make it through a day when I first got it. Part of that was due to my fiddling with it and part due - I think - to the battery conditioning.
Now, it is going a full day on a charge. I am also switching off 3G and on WiFi when I am in my office or home. It is a bit of a pain in the butt and I hope that M$ gives up some APIs soon so that someone - cough Bruce Jackson cough - will write an app. We'll see.

I noticed this as well. As time went by the battery actually started to last longer. When i first got it i used it less than i do now and the battery would die before i even got home for work. Now it lasts till about an hour or so after i finish and get home.
does the surround use the same battery as the HTC desire HD?
Theres an ebay seller that is selling a surround battery and wall charger but the wall charger has a sticker that says: For HTC Desire HD
Excuse me?

He's full of ****. He's never seen a Xoom, much less touched one. I'm getting the better battery life than any device I've ever used.

Completely inaccurate. I did a standby test with wifi on for 8 hours and it didn't even drop 1%. If sales are weak, it is more likely due to price.
This article really upset me! How can this guy make such assumptions w/o citing any sources!??! It's probably taken from the Apple shareholder meeting minutes...
the guy hes sourcing has been completely inaccurate in the past. i would take this article with a grain of salt.
I've definitely had numerous random app crashes but i expected this from a baby OS. I've had no such problems with battery life though...
so far battery life has been excellent
I unplugged Friday morning and didn't have to charge it until Monday night.
I viewed my screen on time and it was at just under 9 hours of screen on.
He's entirely accurate- the 2nd day I got it, my life was on standby for 10 hours while I used it (and still had battery left!)
WOW so should we all post screen shots of the over 24 hours of life we get out of this?
Lol..my Xoom gets the best battery life out of any tablet I've had so far.This coming from a ipod touch 4th gen..a Archos 70 & a dell streak 7.The Xoom's battery life is incredible.

Honestly...I've had mine off the charger for 2 days, 5 hrs, 34 mins., and it's at 34% battery. I will never complain about performance like that.
I'm having issues with the battery life on my Xoom and can't figure out what's doing it...
I can take it off the charger in the morning, use it for 10 minutes then put in standby and when I get home after work it can be down as far as 50%.
I've disabled cell data, put in airplane mode, disable wifi, checked app sync settings (disabled push for exchange just in case).
Nothing seems to help
This is funny.
I had my Xoom on a battery for 4 Days and like 17 hours without charging it. And it was only at 30%! Now, it only had minimal use, of course. I didn't play with it all that much until I received my screen protector. All data services were disabled. WiFi on. So, that's still amazing to have almost 5 days without a charge if you're not using it.
The battery life on the Xoom is excellent!
Did anyone else get annoyed by the insane amount of quotation marks in the article? He might as well have just linked to the source he was pulling all of that fodder from. Plus he didn't conduct his own tests.
Next...
My Xoom matches my old iPad 1, about 10 hours of straight use (reading Kindle books with Wifi/3G on and push Exchange email) or days with mixed use and standby.
I'm running on 1 day 16 hours and I'm still at 40%.
dont listen to that article...the battery life is (in use case scenario) as good as my iPad...
meaning, I don't have to worry about it on a daily basis like my iPad. I think the iPad may get one more hour of vid playback, but the difference between 9 and 10 hours is not huge really.
I went on a ski trip recently and did not bring my xoom...went from Friday morning and plugged it in Sunday at midnight and the Xoom still had 30% left. I did a lot of music playing, web browsing, some gaming, etc.
Standby is definitely longer than 10-12 hours without a doubt.

Please complain. Tiernan Ray is an idiot for quoting an even bigger idiot.
Hello,
new to posting here! To be honest I didnt read that first post as mine seems to last ok, but thats where I wanted some help. Since I got mine this Sunday, when I have it fully charged or not, my battery seems to go down about 10% or so during the night when I sleep. Thats about 8 hours I leave it unplugged. Is that to be considered normal? I am just coming off the ipad so 10% feels a little bit more then I'm used too.
I leave wifi on all the time, but no bluetooth, no location services or whatnot, I do leave on that background sync though, would that really drain me that much though during non usage time?
Again, not major but I would like my battery to last as long as possible =]
Thank you for your help in advance!
BTW, love this Xoom!
I put up a good comment at that site. What a douche that guy is. I think that article should be taken down for retarded opinions/claims. I know they said everyone has a right to an opinion, but... this isn't an opinion it's a complete BS claim to try and make people look at the iPad. Hehe.. sorry to burst your bubble there guy, but... us Android users already know the truth about how awesome we are.
Yesterday we had a day grey in grey and I started my morning as usual with my SGN 10.1
Emailing, Newspaper reading, some drafting for my next lectures, updating apps and then I found some really funny cabaret streams .......
Well, my Note was constantly on and streaming YouTube and some other sources
What shall I tell You: just in time I went to bed it was down to 5%
14 hrs !
No other tab can beat THAT :laugh:
I found a quick way of gaining 5 hours battery per day: I bought my 5 yr old son a Galaxy Tab 2 (early xmas present). Now my note 10.1 lasts me all day, every day It even works with my phone, a Note 2
My note 10.1 has so far been running for 23 hours and 10 minutes and has 26% battery remaining. It's definitely on a par with my previous tablet, an ipad 3 :good:
Last week, took mine off the charger Sunday morning and didn't put it back till Friday night. I didn't use it much, just about 4 hours of screen time. Total time on battery was 134 hours 27 minutes. Still had 55% of the battery left. That standby time if phenomenal.
yeah my last charge was 5 hours 40 mins screen on time and more than 13 days standby. Battery was at 34%. It uses next to no power on standby, absolutely amazing.

I use my Note 10.1 on two day cycles. I am in college and take all my notes with it. I can use the tablet as much as I want and I get two days of battery out of it.
I agree. I'm coming from Asus Transformer Infinity and SGN 10.1's battery is beyond belief. It seems like it's running on nuclear energy. Amazing for such a light tablet.

guys why my screen always say it uses 75/80% when i look at battery usage ?
it makes my battery drain very fast
The amount of time your screen is on is the usage percentage shown eg if you tablet is on for 10 hours and out of that u were using it for 8 hours then the percentage would be 80
Screen is the biggest battery eater which is the case with any device so it effects your battery life the most

I think its what percentage of your battery it has used, not the screen uptime vs total uptime

I got mine yesterday and charged it, hardly did anything with it except download and play a game for less than 10 minutes and have a little doodle with sketchbook pro then left it on standby over night then did a little browsing this morning.
Found the wifi to be slow and sluggish and wouldn't even show all images even though my broadband is 100mb speed.
The battery lasted 13 hours, don't know how long it would last if I'd actually used it a bit more cause it seemed to go down pretty fast even on wifi bout the same life as my s3.
Hardly call that phenomenal.
I'm really disappointed to be honest after reading all the reviews.

Somethings up with your device maybe........ive tested mine a few times, constant use, thats, from 100% untill the 5% warning, mostly browser and youtube......5min break here, 5min break there...........on average 10h MINIMUM of CONSTANT use.........if your dropping 13h without much use, then somethings up with your device and might be worth asking in the q&a thread for help
Are you using full brightness?

Probably just needed a full charge as I only charged it from half way as it came half charged and if that doesn't work I'll do a full discharge and if that doesn't work I'll send it back
Full brightness is too high for me and auto is too low so had it at less than half way.
Only really got it so could use it to take out with me and do some paintings but was worried about it switching off that's why not happy.
Thanks for your reply, really like this tablet and it really is what I thought it would be but if it hasn't got the battery then it's not good.
I'll see how it goes.

Make sure you set WiFi to turn off when the screen is off.
Odd though that the WiFi was slow. It makes me think something is wrong with the WiFi itself that's causing problems.

Personally, I've noticed that the s-pen digitiser, when it is switched on, drains a considerable amount of energy. So do not expect extreme battery life if you use a lot the s-pen. Anyway, do check that the energy saving option under "Options - S Pen" is ticked. This way the digitiser will be off when the stylus is in its receptacle. This will save a good amount of battery when you're not using the pen (provided you insert it in its receptacle). Of course, this setting will have no effect whatsoever while you're using the pen.
In any case, a tablet like this is full of features and components that are potential battery killers, so how long the battery lasts, it's really up to how the owner uses it, and not only how much. For instance, I may be surfing the internet and checking emails all day long without using the pen, and consider it heavy use. How long will the battery last in such case? 15 hours? Ok.
Now, a seemingly opposite case could be this: I may have the tablet constantly standing by, but with the pen off its receptacle. Since I have never used the tablet, I have full right to swear that my usage of the tablet is extremely light. Well, only because I've left the pen out of its receptacle, my battery will run flat in just about 13 hours or so. And what's more confusing, is that if I go checking the battery stats, I will see no trace of the pen being the responsible for such a high drain, so I probably will end up getting the (wrong) idea that the battery life of this tablet is extremely poor.
Another case, among the many, is when the tablet tries to sync using the 3G connection, but gets no answer from the network because of problems of the mobile operator network (server not responding). This causes the 3G radio to remain constantly on and drain the battery very fast. Again, it is very difficult to understand the reason for such a quick discharge. Such an issue happens in certain areas of my city with Vodafone, for instance. When I go to that areas, I have to take care to switch off 3G data connection, or else my battery will be empty in a matter of a few hours.
IMHO the problem is, that android os is very incomplete when it comes to providing information for analysing power consumption, and this has always been the cause of big confusion and frustration.

Ah think that was it thanks had the battery saving in pen unticked, wasn't sure whether to tick it or not.
I only have the wifi as got 3g on my phone so don't need it.
Main purpose bought it for was the pen but now have that ticked when not using it should make a difference
