I am a bit disappointed with the drain of the battery compared to all other tablets available out there. Mine drain like 1% in every 4.5 mins when you use it for browsing websites, which last only 7.X hours.
7 hrs for me is acceptable but i am just wondering hows everyone else doing on their battery. Do you like it so far
My battery was draining pretty quick for the first two or three days but it's settled now and seems to be getting better.
Same with me. It started off draining quickly, but I've noticed that it's getting better. The battery life may not be the best out there but it's reasonable enough.
I can maximize my A500 Tablet more than 10hrs. only when I'm using Battery Booster v3.3 but if not, until 9.5 or exactly 10hrs only.
Yeah same battery was burning quick initially now its pretty even and like an idiot I left gps ticked on indoors which certainly didnt help
Yeah, I can confirm that the battery life has gotten a lot better after a week of using it.
I returned mine because of an issue that the gray cover part of the back was coming out very easy, I got a new one and this one drains battery very very slowly even at the first charge!
I must admit iam not that impressed with battery life so far,it drains about 20% overnight in airplane mode.
I charged mine to full last night used it for web browsing and music was down to 68% after two hours.
This morning was at 48% left on airplane mode this morning until 1pm was at 17% when I got home.

A lot of the pre-launch reviews warned about battery issues, so I thought it would be a problem. I have been pleasantly surprised. I charge it once a day in the cradle. I use the tablet most heavily at night, and usually have a half battery in the morning. The first day I had it I went several hours on the 20% it had out of the box. Not bad at all.
I was using mine for about 3 hours last night and coming from a full charge I still had 80% battery left so it's definitely improved a lot
my battery goes down about 10% every hour... while watching video using bluetooth MW600 with wifi conneected to my phone...
n my x10 battery goes down about 30% per hour, sad...
Got no problem with battery life got a problem with recharge time tho it is real slow.
How is the standby time of your Tablet S? I have 80% battery left on last Friday, but this morning (Monday, that means has been two days more), I can't boot my device, no juice left in my tablet S. I did not use it on Saturday and Sunday. This is very weird.
According to the Sony website, the stand by time is 400 hours, of course I don't believe these numbers. But let's say 200 hours standby time is worth to trust. My tablet S doesn't even last for 48 hours. Has anyone encountered the problem I had?
so far im not convinced by the battery. I purchased mine on Friday and hoping what everybody else says is true - that it gets better after a few days, but I suspect this is due to the "honeymoon" period being over and people stop playing with it as much.
I put mine down last night at 95% at around 10pm. I checked again this morning at 8am and it was down to 65%. To me that doesn't quite sound right. I've turned off all syncing and location services now and Wifi is set to go off when the screen turns off so I will see how long it lasts after a full charge tonight.
I am starting to feel really disappointed by the battery life... =(

Same here !
The S1 drains the battery really fast over night.
It seems that the cpu is always active and dont use something like a "sleep mode" ...
Anyone has suggestions what to try without root ?
I have returned my tablet. However battery life was worse then the Jetstream and worse then the Ipad2
It might not be a Sony problem. Check your apps. Android doesnt have that good of control over apps like Apple has so they are not all optimized.
You will be surprised how many of them will eat away at your battery even in stand by.
Here is how i test it. I go into Settings>Applications and go and force close every single app that im not using. Then i put the tablet in stand by and check it after a few hours. I say a few hours because after one hour the battery doesnt even move in stand by.

I get what you're saying. Though, there is definitely something wrong with this (or my) tablet's battery life. I have closed apps, and even turned off all the radios overnight; but I went from 74% to 34% in just 10 hours overnight in standby! This is unusual. I charged my tab yesterday morning, and used it very moderately. I used to have a xoom and a tf, but they would probably still have roughly 75% - 85% left?!! Maybe this is a hardware issue on my tablet, specifically? I can't return it. I am about to call Sony about this. Does anyone else have dramatic battery drains like I have been experiencing?
EDIT: Food for thought - I once had my xoom last over 21 days in one charge alone! This was obviously with VERY little use, but the Sony tab wouldn't even last 5 days in that scenario?!

The specs for S tab along with the battery type in it should last but for some reason it is inconsident. Ive had days where Ive turned it off at 90% and turned it back on later in the day at 89% and somedays its gotten as low as 60%...for no apparent reason. So something is odd.

I've not been able to drain this thing since I got it a week and a half ago. I have to say that I like to charge things over night. I've not been able to get the Photon below 40% before I go to bed each night.
I hear that you need to drain it full at least once but my habit of charging things overnight is getting in the way. Should I just let it go overnight one night?
I was under the impression that completely draining Lithium Ion batteries causes more harm than good.
"The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery."

Also, i'm sitting at 46% after 15 hours of normal (for me) use. not to shabby. I should mention i'm running Juice Defender and build 4.5.1A-1_SUN-198_5 from the dev. forums and i'm connected to WiFi 90% of the time.
going to try tomorrow without Juice Defender and see how it does. After that i'm going to disable SPB Shell and see if that makes a difference.
Thank you sir. I don't want to root my phone so don't run Juice Defender but I do use the Data Saver in stock a lot. I usually just listen to a lot of music and look for new stuff on FB, check XDA forums blah blah blah, yada yada yada...
I'll not feel paranoid about charging my phone now lol.
Now with my tablet (Acer Iconia A500) I did root and load a bunch of different stuff. This is my first cell phone though and I didn't want to mess with something that I have to pay a monthly charge for. I know I could but it's my first cell phone lol.
How much are you guys using it? For me, I use about 30min talking, 1 hr heavy wifi use, 1 hr light wifi use (reading), 30 minutes playing with settings, and the rest of the day idle...that gets me to about 30%.
I actually thought that is kind of weak. Maybe my battery isn't as healthy as yours? I've only had it for 5 days. I charge it every night.
I use it for about 7 to 8 hours of music, FB updates/posting, checking XDA, about 10 minutes of calls and so far some Netflix watching just to show off the phone to my peeps. Oh and some picture taking.
I am the same way I hate to discharge it completely and its been very hard. I've went a day and a half without charging before it went under 10%. I will say that I am on Wifi 90% of the time as I have wifi at work and at home other than that its on performance mode so no true bells and whistles. I'm thoroughly impressed coming from the Evo.

Average day for me is about 30 to 45 minutes of phone calls, 80 to 100 texts, few conversations on google talk, 30 or so emails on three accounts and i have trillian running connected to two accounts.
Connected to WiFi most of the time, bluetooth is turned on (not connected most the time) and brightness set to Auto.
I really dont see how this phone is a monster when it comes to battery life, I've actually been getting the exact opposite. I just fully charged my phone and after running for 2hrs and 7mins its down 78%.... This phone has yet to last me for the whole day. What am i doing wrong? I dont have tons of widgets and the only app that im running that might pose a problem is Go Launcher

Is that your screen on time? If that is then I would say that is impressive already. When I had the epic on stock if I use it for 2ish hours screen on time. I would need a recharge. (Got a lot better after using custom rom. Around 4 hrs screen on time before recharge)

For the past couple of weeks I've been swapping batteries with an external charger one to two times during the course of a day (plus the overnight charge)... Looks like it's time to do some housekeeping...
Edit: used to have battery life like everyone else in this thread though! While at the climbing gym last night I noticed that the thing felt like it was about to catch fire against my thigh - it had burned through about 60 percent of a freshly charged battery in about two hours. I have a nagging suspicion that I neglected to uninstall something (or a few things), and now something non-existent is constantly being polled for as a service after I launch some app for the first time...
when i got my phone it did great on a full day charge, but now with it just sitting at the office its at 70% by 11am i take it off the charger 7-8am .. it started to "weaken" after i downloaded a ton of apps i leave wifi on and 4g off but it also depends on your signal strenght at home it will kill the phone halfway thru the day because i have one bar
Well, this question is for my lucky friends who have their new toys
Battery life is so good?
Post your test here!
Don't have screens for ya but battery life is more than adequate. My gf and I used it for about 5 hrs last night and it dropped to about 45%
(Games, xda, Netflix, and just tinkering around)
I'm curious what kind of battery life you folks are seeing, now that you all have had time to get some real world experience with the NT.
Thanks!
10 hours of continuous usage with 25% brightness.

Yea, the battery life and responsiveness of the device is definitely top notch.
I'm pissed as hell the bootloader is locked, but this device is an absolute steal for $250 bucks. Especially if you can manage to discount that price down.
Extremely responsive and awesome battery life considering I'm running max brightness and wifi 24/7.
I'm always surprised when I'm done using the Nook that it was still running. Granted, I ran it until it had only had around 20% left. But hey, if your sitting in one spot using your nook for more than ten hours, then you need to find something else to do. ^_^

Good book, nice day, under a tree? Done that many times just reading off my PDA.
Thanks for the feedback!
The battery life is definitely adequate.
I can usually go 2 day without charging thus far. I keep brightness at ~20% or so (I can't stand brighter, it actually bothers my eyes).
I also use multi-picture-live-wallpaper and it doesn't seem to drain my battery at all.
I do some pretty heavy use of it as I am reading on it and studying for med school for probably ~6 hours at a time
Battery life is great. BN's numbers seem dead on.
Lasted the flight from San Francisco to Sydney
I'm getting around 10 or so hours of use at 2/3 brightness. Battery life is amazing on this. I charged it last night. Took it off the charger at 10am didn't touch it till 10pm tonight. It was at 99 percent then. I think it turns off wifi when it's sleeping.

Yeah, it definitely turns wifi off on its own when sleeping
Yeah Ill echo the comments here, battery life is absolutely superb and the responsiveness of the unit for the price is fantastic. Sadly its a case of if only B&N....to fully realize what the tablet would be capable of.
I have to agree that battery life is amazing on this thing.
I've got wifi turned off full time (to avoid updates from B&N) and the battery just seems to last forever. Granted you always use less battery when you're not going online, but still, it seems to really really last.
Frankly it's making my phone quite jealous.
Umm, my nt's battery isn't as impressive as i hoped. I use 25% brightness, wifi on, no fancy live wallpaper. I noticed for every few minutes of sjurfing, battery would drop a percentage or so. For usage of about 3hr withoit wifi, i would use up about 40 %.
Anything i could do to tune it up a bit? I do noticed amazon appstore is always running, so is clock, contact, tb, and my yahoo mail app. Any help is appreciated.

That sounds about what I'm getting and I'm wondering whether it's defective or not (still within return window).
edit: Probably normal - ran into some threads on B&N's boards where other people are averaging 5-7 hours. If I idle / read, I get about 1% every 8-10minutes or so so B&N's time estimates were definitely not "video," "browsing" or "games." Wifi on, installing or rebooting a few times, it drops to 5-6 hours tops between 100% and close to 0%.
My phone gets -way- more time, even reading.
the battery on this is great one of the biggest things going for it. better than my phone for sure.
For you guys with bad battery life, you might want to try better battery stats. Then check for partial wakelocks. That's usually the culprit on my phone. It seems weird some of you are getting half the battery life of the rest of us. Personally I haven't even turned wifi off at all, and also haven't turned my brightness below half.
It's in the google market, it won't show up on the nook. I downloaded it on my phone then used the app share my applications then back up to sd. Upload to dropbox. Then download it with dropbox on your nook.

I looked at this (and other battery programs), but wasn't sure what they did. Now I sort of do. I'll check it out! Wifi on definitely uses up at least 20-25%ish extra battery, and I *have* been moving a ton of stuff to/from sd cards and uninstalling and rebooting a lot, but the above did seem very short. Too bad there isn't a battery hardware test
Failing those applications it may be worth doing a full reset; Especially since most other owners are reporting MUCH better results.
Before I start nuking things around, I used BetterBatteryStats, check for partial wakelocks, and the highest % is from ActivityManager-Launch, which occupies 0.3% or 5minutes or so since I fully charged it.
Also, i noticed "Wifi Locked" is extremely high, like 89%, whereas wifi On is only 26%. What does that mean?
I'm not fully versed in how Android handles power management. So what should i be looking out for? Thanks!
There's been mixed reviews of battery life in the CM7 rom for the NT as far as battery life is concerned, some are saying they've run it with moderate use since the day it was released and only used about 20 - 30% so far while others are saying battery life is terrible.
SO I thought I'd start a little poll to see what people are getting, I'm guess the battery drain is due to various software being installed so not really the OS's fault.
For me the Battery life is greatly improved over stock, for instance I took it of charge 10 hours ago, it's admittedly only been used for a few minute son and of during those 10 hours but it's lost the grand total of 4% battery in those 10 hours which I consider pretty good really.
Soi lets here what everyone thinks, remember to vote !
Battery life - improved
This is my third day on the CM7 alpha - battery life has been much better than before. Considering I have probably spent more time with the NT turned on over the last couple of days than I normally would, the battery used is less than normal. Previously I would use about 60% of my battery per day. Now I am using 30%-40% - and that includes downloading and configuring many, many applications.
I really think its much better than stock in my cm7 nt
No problems here. Take off charge around 6am and return to charge around 10pm with usually more than 80% left depending on usage.
Sent from my Droid Incredible ICS 4.0.3
I don't think mine has been on a charger for the last 16 hours or so, light usage, wireless has been off most of the time, and I use a task killer to kill things before I turn off the screen. Didn't power off, just put to sleep last night before bed, it's still at like 85%.
So far, it seems better than stock battery life to me, or at least no worse, and I have a lot more apps installed now.
Edit: Internal version.
It might help if folks said if they were running off SD card or internal memory when looking at battery life - I have the impression that the SD card reader on the NT is something of a battery vampire.
Internal CM7 since it was released.
Live wallpaper on Golauncher
wifi set to screen off-off
Brightness at about 60-65%
It's been off of charge for 4 hours 21 minutes this morning and I'm at 96%
Dolphin HD and Gmail have been running all that time.
Hasn't been out for long enough to really tell but my impression is that it's about the same as stock.

Odd. Is that your aforementioned case with lots of standby? On my Vibrant, the Screen bar generally dwarfs all other bars even with significant standby time. Granted that's an apples-to-oranges comparison... (I don't have CM7 on my Nook Tablet yet - can't do a comparison between stock B&N and my Vibrant at the moment.)

Yes. I don't really know what "standby" means. This use was about 40 minutes of checking email, weather news and etc followed by About 2 hours with the screen off then an hour of dinking around. Watched all the superbowl commercials, staying up on XDA and other forums with Tapatalk and learning things in CM7. I'd describe this as light use bordering on moderate.

Watching video or playing games can be quite intensive. Flash is probably the most intensive for video playing.
Keep a good eye in it over the next few days then cone back and post if you've noticed anything that makes it better or worse with battery life
Last I checked mine was going on 18 hours and at about 40%
One thing I noticed is that the charger for my Moto phone doesn't seem to charge the nook as well as the nook charger. I'll have to look at the nook wall wart and see if it's pumping out more juice. For reference the Moto charger is only 4.33W (5.1V at 850mA).

What kind of usage? Low, high, moderate? Just curious because my wife and I do a decent amount of Netflix (1-2 hours a day) and I don't have to charge more than every 3 days. This is with 1.4.0 rooted. I've been exceptionally pleased with that - power consumption in standby seems to be incredibly miserly with stock (most likely due to WiFi being turned off when the system is in standby).

On the subject of the battery, I posted about an issue I encountered last night, here:
http://forum.xda-developers.com/showthread.php?p=22261812
Additional information: At the time, I was fooling around with a playstation emulator, which i'm fairly sure constitutes a heavy drain on system resources. Battery drain seemed appropriate for the level of activity.

Internal install, wifi off during sleep. Figure the end of the graph was about 19-20 hours or so of sleep. Before that was a constant internet, twitter, WWF session. Screen brightness is in the bottom 1/3rd of the slider.
I am going to beat the hell out of it tonight and will see how the battery holds up. Looks pretty solid just sleeping, so we will see what it can do under load.
So found that if your wireless location is turned on, it will wake your NT about every 5 minuetes. That's not a good thing
If anyone is seeing drains, i suggest using betterbatterystats to help track down the culprit.

So Im getting horrible battery life with this now. Not really sure whats going on. I use to be able to leave my nook on standby for days and last night it was at about 30% woke up this morning and it was completely dead...
The first week I had my 920 I was lucky if the battery was at or above 40% by 12 noon. The 920 is my 2nd phone line and I am using it mostly to learn WP8, to surf the web some and listen to a lot of podcasts, usually 6+ hours of them a day. The past 4 days the battery in the 920 is showing insane runtimes. It is currently 11:30pm and it has been off the charger since 8:00am, over 15 hours with overs 8 hours of audio podcast listening. The battery is currently reading 61%. I originally got the impression that LTE was killing the battery, but that is no longer the case.
I have a Share Plan with AT&T with 2 phones, a Galaxy Nexus (GSM model from Play Store) and a Lumia 920. I use my Nexus as my main phone line, to access GMail and Google Reader (a lot of Google Reader feeds). The Nexus has been off the charger the same period of time and is showing 41%.
For me wifi destroys my battery for some reason I get 15 hours with wi-fi on or 28 with it off
Interesting, mine will usually run for 24-30 hours before hitting 15%, including regular usage. 4G gives it a whack but generally I find similar to other phones, if low coverage it chews the battery
Reading all the doom and gloom of 4G LTE on various mobile phones, after my 1st weeks experience, I was expecting similar results going forward. But, after 2 weeks of use, the battery falls in line with the results you mention. And, with that I am not complaining.
same situation here.
It looks like the phone needs some days to warm up and get long lasting.
Also I see that wp8 is heavly optimized for background task in order to not consume a lot of battery eg: my phone lasts more than 2 days with light usage.
I listen to podcast for many hours and it doesnt affect the battery that much, in fact I'm surprised by it because I know audio playing takes a load on the cpu.
Mine.. overnight without charge or using the phone it drained from 100% down to 35%. BS
Two words: Background tasks.
Make sure you don't have unnecessary background tasks running. I have less than 5 and my battery runs more than 2 days easily.
How do you kill or monitor background tasks?
I had really good battery time of 19 hours the first day of installing the new firmware, then I enabled bluetooth again and it drains like crazy. its hit or miss but people seem to think that whatsapp drains battery. I personally would like to disable LTE (its really slow in my area) and just keep bluetooth that seems to give me 12+ hrs of battery.

You can block background tasks for 3rd party apps in Settings->Applications tab->Background tasks. There is no way to monitor these tasks because WP OS doesn't offer any such capability.
Unfortunately there is no easy way to block 1st party apps and if they are misbehaving (like sync something over and over), there is nothing you can do about it.
Turn on Battery Saver can also effectively kill all background tasks. But that's draconian. I still would like my smartphone do something in the background for me.
Don't forget, the biggest battery drain factor could be your cell phone signal. If you keep the phone in a fringe area, the cell radio will drain your battery very quickly while try to maintain communications with cell towers. This is outside the OS and you can't do anything about it.
I had a weird battery drain the day after the last upgrade. No apps running in the background BAR the movie that i had paused.. I lost 80% without using the phone in a 6 hour period (post charging). After a reboot it seems ok. Perhaps i should pause another movie to see if it happens again....
I must say that I have mine 2 days and the battery drains too fast... I dont know what to do .. Maybe because its new ? Some one can help me maybe ?

My battery is pretty inconsistent. MOST of the time it's awesome, and will last like 20-25 hours without needing to charge, but that just makes it especially jarring when every now and then I go to check my phone at 4 in the afternoon and it's at critical, and I have no idea what causes it.
Plus when it does die I have to put it on the charger for like 2 hours before it will let me turn it on.
I found interesting point in the battery life today, if the screen is off, the battery drain is in the range of 3-4% which is good, however, if the screen goes on the battery drops like 15% in just 25 minutes. After thinking I tried to set the screen sensitivity to normal and it solved my problem. I kept the screen on for more than 45 minutes and the battery went down almost 6% only which is good. I still have to test more to give a concrete evidence.

I usually run a battery discharge app Saturday night. Then a full recharge with the phone off. That usually gives me dependable battery life of about 12 hours a day for the entire week. If I forget and not run the discharger I notice it midways into the week when I only get about 8 hours out of it.

after updating my phone to the 1314 update, my battery life got worse.
I went from 14 hours per day to only 8 hours.
thanks nokia -_-
note: I was not experiencing any connectivity issues on my phone.
let's see how many people here actually have NFC on and Auto-Brightness on... lol
I used the sleep app last night after charging to 100%, and then I fell asleep with it on.
I woke up to find the sounds still going, and when I checked my phone worried that I killed the charge, I found it still had 92% left. That's impressive.
The battery of my tablet has become terrible the last two days.
Previously I had no problems lasting all day.
The last two days have seen an 80% drop in a few hours.
Has anybody else had a similar issue?

Not as bad as that, but I have noticed the following.
I got my tablet on Tuesday and immediately activated Stamina mode etc.
Overnight I left it in aeroplane mode and it lost just 1% battery.
Yesterday during the day at the office, again it only lost 1-2% in 9 hours.
Yesterday evening I let Google Play sync and restore some of my apps etc. But, I also went into setting and disabled and un-installed stuff I did not plan to use.
Overnight it lost about 8% - again it was in aeroplane mode.
Today at the office it has lost around 7% over the past 8 hours.
Not sure what is going on.
I installed a battery saver app and it seems to be better.
I suspect a recent app update was responsible.
My tablet went on for 2 weeks 14 days on one charge with light use throughout that time very happy with it.

Last night mine only lost 1% overnight...
And so far sat on my desk it has only lost 1% in the past 4 hours...
Weird.
Gah73 - which battery app did you install? On my Z1 Compact I never found a battery app that helped - Stamina mode always seemed to give the best results.
Thanks!

I never use any battery app I put tablet in battery saving mode that's all.
Same here. Usually i'd be at about 78% after a day of normal usage, today i'm at 58%.
SGP621 / LTE here. I also suspect some updated app, as I updated yesterday.
From power usage stats it looks like Asphalt8 might be the bad app... 27%.
Anyone with the same problem and Asphalt8 installed?

I was using battery doctor - I have uninstalled now though.
I agree the built in STAMINA mode is pretty good especially with the Extended standby on.
Also, I do have asphalt 8 installed so it could possibly be that.
I think Battery doctor is a good app.
2nd charge much better!
Ok - just to update, I charged the tablet for the 2nd time since purchase on the Sunday before last i.e. 11 days ago.
This afternoon the battery charge finally dropped to 14% and so I have set it to charge again.
Over the past 11 days I used the tablet for around 10hrs in total - most of which was watching HD videos on a medium brightness setting using MX Player Pro and earphones. Spent maybe 1hr total downloading / updating apps and checking email etc.
I strongly believe I could have made it last through till Saturday before I hit 0% battery - based on the daily average battery usage of around 7-8% a day.
Overnight in Aeroplane mode it lost around 1% each night. Also, note that I had Auto-sync switched off for the majority of the 11 days - so if you have it switched on - you battery life would be affected.
