I humbly admit this TouchPad could NEVER be a replacement for my iPad2 regardless of APP count or flash or anything else based on PURELY the battery life. I left this TP (running CM7) in my backpack yesterday afterwork with approximately 36% and woke up this morning with it at 1%. I won the ipad for work so kinda figured I could sell it and recoup some cost seeing how the TP was considerably cheaper but boy was I wrong.

Im sure the iPad 2 kills the TP on battery life and other areas, but you can't compare CM7 or CM9 which are still Alpha stage and have bugs that are being worked out. But if you switch to webOS you wouldn't have that problem. I have left it days without charging on webOS and it holds charge like a champ.

Well I also won the 32gb ipad2 for work, so it's not exactly like I had to come out of pocket for it.. Yes, I'm an ex tech junkie who was a flashoholic but at the end of the day, this new technology is more or less just modern day toys for all intents and purposes. Any pad I ever own will never be more than a cool electronic device for my kids to game on, to Netflix and YouTube on, and occasionally get some work done. In THAT regard alone, I kind of assumed the TP would replace my ipad2.. Guess I'll wait for better software and see what the battery life does but that is arguably the biggest advantage to Apple stuff and they don't get NEARLY enough credit for.. battery conservation, they sure have gotten good at it.
My guess is you probably left any number of things on that drain the battery: screen, bluetooth, wifi, etc. The only difference between these is that the iPad probably turns some of those off by default (such as the screen when it detects a cover over it). There are a plethora of mods and other trackers for Android that can automatically control that for you to save battery life.
So yeah, you're naive.

CM7? And +30% drain on an overnight? I can only assume you're doing something wrong. Even if you say got home at 6pm and left the device in your bag and woke up at 7am, more than 30% battery on 13hours is too much burn. If anything you probably have some stupid apps running (Facebook) that prevents the device from going to sleep. Last I ran CM7 I remember the drain to be 2% an hour at most.
On CM9 the battery burn is less than 1.5% an hour with a couple tweaks. I say switch to CM9 and figure out what you're running. Maybe its a Google sync thing not completing, but its almost always Facebook.
Samsung Captivate CM9 - Glitch Kernel | HP TouchPad CM9 - Bricked Kernel
Admittedly naive but this thread actually proved useful as it gave me some tips on things to check. I purchased Tasker for my Thunderbolt awhile back and a big selling point to trying to get this TouchPad working was being able to double dip on apps already bought. I know w/ Tasker I can automate a buttload of stuff including auto wifi settings, dimming the display, turning off unused apps, etc etc. Thanks for the tips guys, I knew it would never compare to the ipad but from the sounds of it, it might be relatively close. Any CM9 ROMs you best recommend, there appears to be a ton and I don't know where to start.
First of all CM7 is an alpha, and second of all why are you still using CM7. The CM alphas, even CM9 don't have the best sleep battery life, but its better than CM7. If Apple released an alpha of iOS created by volunteers only, do you think it would be polished and perfectly working.
Had flashed a friends TP about a couple of weeks ago to CM7 and followed the CM9 threads which said it was easier to start with 7 then upgrade to 9. Never followed the second set of instructions, doing now.
I use my TP for work running CM9... Mostly read PDF files on it so i don't have to print out a 80+ Page document.... so the screen is constantly on and off from 9 AM till about 3 - 4 PM and i can do 4 days like that with a single charge... BTW i dont shut down i just simply put it in sleep when i pack it in my bag for the next morning
and even when i go to charge it im at 30%... so its not like critical low
OP... boot into webOS for a couple days and see how your battery life is there... if its using 35% in sleep mode OVERNIGHT than there is something wrong with ur TP
What I don't understand is why we can't emulate what the iPad does to conserve battery life. An iPad and a Touchpad both running nothing should be able to have the same battery life sitting idle. An iPad essentially loses no battery life while sitting idle. Why can't we just do what they are doing?

Because the iPad and Touchpad have literally nothing in common. Completely different CPU, GPU, batteries, wifi radios, etc. Apple also has an advantage in that iOS is only made to run on a small handful of devices on the market whereas Android has to target everything, so its much easier for them to minimize power consumption.
The touchpad port may look like its really far along (and it is) but right now battery life is still a lower priority for the devs. Keep in mind that the Touchpad was never meant to run Android and the version we have was made by hobbyists. That we have something that runs at all right now is nothing short of amazing and nobody has any right to complain unless they're willing to jump into the code and fix things themselves.
Better battery life will come with time. Just be patient.
I'm running CM 9 KANG 20301 nightly.
Taken off charge 09.30, use throughout the day at various times and for various periods, wifi on all the time, now reading 50% remaining.
That's good enough for me.

iPad Development
-many paid employees
-able to design OS around hardware and build drivers
Touchpad Android Development
-volunteers with other jobs
-have to work with AOSP/CM9, many drivers are proprietary
If we had the employees/resources Apple has working on iOS for the iPad building Android for the Touchpad we'd have a stable version by now. You can't compare the two. Also CM9 is called ALPHA for a reason, its NOT supposed to be stable, its going to have issues.
It's worth noting, as has been pointed out several times now, that you're comparing the stock iPad OS with a completely unofficial and voluntarily compiled secondary OS for the Touchpad. If you look at any of CNET's tablet reviews, the battery life for the HP Touchpad running webOS was actually quite comparable to the iPad2's.
Just flash the latest version of classic nerd ICS and you will change your mind. Battery life on the latest version is freaking amazing. I have my tp running 3.2 classic nerd, overclocked to 1.5GHz and it will last 2 days with moderate usage. Simply awesome
http://classicnerd.net/
Let us just call him naive and call it a day. Once battery life gets past a certain point, who cares about another hour or two? Now if you gave me a tablet with e-ink battery life... Will have to wait for Mirasol for that, I guess.
The TouchPad with dual OS's rocks! Who wants that flashless FruityPad with its walled garden?
Yeah, I echo some comments here. Why are you still on CM7, its terrible. CM9 is tablet optimized, and it only takes 4 seconds of the ICS to see the night and day difference.
I too get several days of standby on CM9 Alpha 2. And awesome battery life on webOS. I also enjoyed webOS, much better than CM7. At least webOS is tablet optimized, and made for the hardware. So, its stable, elegant, intuitive, and once tweaked very snappy and responsive.
If battery life is your primary concern, use webOS. Its got a few tablet apps, and a solid browser. But, if you really want Android give CM9 a try.
And remember the age old xda addage; if you want an apple product, don't buy a non-apple product. This happens far more with the phones. Android is only well received by the person that seeks it out. If you are stuck with an Android device, you will hate it. If you only switch from iOS to android "because of boredom" you will hate android. At the end of the day only you can decide what's best for you. </rant>

TP isn't really a competition for the iPad2
Actually almost any other Android tablet > TP.
It's just that... the TP is much much cheaper.
Please lads, I get days out of a single charge. If you noob and can't manage apps yourself get ipad. Like the idea of being in control of what you pay for, get touchpad. I completely love mine, minus HDMI out.

Well, just migrated to phiremod 5.3 and found this problem with my nook.
4 days ago I went on a trip, and left my nook at home, then today I came back just to find its battery was drained out!!!
Does anyone have the same problem? If yes, how can you fix it?

Well, two things here:
One unless the device is totally, totally shut down, this will happen on any rom. Even though the screen is off, the device is still running (which is why tapping the power button brings everything back instantly).
That said, CM7 based roms do currently use more power right now, since they don't sleep the same way other roms do - they stay more active. This is top prevent a gnarly bug however, and is currently int he process of being fixed. In the mean time, it will mean your device uses a bit more battery, and just need to be charged more often.

Thanks a lot!
Currently CM7 battery drain is about 2% every hour, so if you had a fully charged nook and then turned off the screen, it would be dead after about 2 days.

Yes, this is sheer and utter BS - the Nook is not a phone, nor will it ever be one. The confusion comes from the use of Android builds made for phones - "cell standby" merely means that the device is idle!

Personally I'm staying away from CM7 until this bug is fixed >.<
48% of battery life a day just from standby is too much
That is my thoughts right now on this too. I am running the Nookie-Comb rom for now until I see the battery being improved on CM7. I really like the developers work on CM7 and know they will get it going right soon enough, but for now, I will stick with this rom.
I was flying through my battery before, mainly because I play around flashing things and playing every game in the world on my NC. Since I went over to the Nookie-Comb rom, all seems well.
I went to bed Sunday night around 11:30 PM and left the NC unplugged. It was at 88% and when I returned from work on Monday at 4:30 PM, it was at 87%.. I will take that.
As of now: 78% Tuesday 8:00 AM
I gotta say, you all are missing out. CM7 is better than the Froyo builds, especially since you dont have to risk the SOD. And its not exactly hard to throw the nook on the charger at nite. But, have fun being behind i guess..... :-s

I have to agree, CM7 is rock solid! I have played around with a few other froyo rom's, but all have one bug or another I am not willing to accept. I have found NOTHING wrong with CM7 yet, other then the battery issue. I just fully power down my nook when not in use. I'm also running CM7 on my CliqXT and have been very happy. What's the big deal with having to plug in every night? Most of us have to do that with our phones anyway...
Yeah, while I'd like it fixed, for me I am just doing the same routine I do with my phone, plug it in at night. At least I don't have to plug it in at lunch time too, like I do with my phone... I always have 40-50% remaining at bedtime on the NC, which is more than enough buffer for misc stuff.
Although gotta be careful with games, they can suck up to 20%/hr off the battery, so I made a shortcut to the CM Perf settings and downclock it when I play some of them. Say Zenonia 2, 600mhz plays same as 1100mhz but 13% vs 21% per hour battery usage.
Stock I plugged in about every 3 days. But I'm also using my NC more than I was on stock too, so that's a big difference. I can use OpenVPN on CM7 thus I can sync at work now, plus it's more of a pleasure to use the NC on CM7 so I'm just overall using it more.
Standby time of .2% vs 1%/hr (when wifi is turned off at screen off) isn't that big a deal if you're using it a lot anyway.
Hello all,
I'm currently a Samsung galaxy s2 user, just switched from using the iphone 4 because of all the rumors about the galaxy s2. And till now im impressed by everything it has to offer except its battery life.
I love my galaxy s2, but the only problem is battery life, and thats the main reason im being pulled over to buy the iphone 4s!!..
getting that isnt the problem..
I tried way too many custom ROMS, different kernels etc, but ended up with an average 6-7 hr battery life with heavy usage and that doesnt even involve listening to music while commuting. If i did that as well, im sure my battery wud barely last 5 hrs... which isnt ideal at all, im sure everyone feels the same way... Right now im on stock KI3 firmware, rooted. KI3 is slightly better than what bell gave me as stock - KG2.
now i want some strong points of why i shouldn't move back. I've been an iphone user since the 2g iphone and it was amazing!
Only if i could improve my battery life on galaxy s2 i wouldnt have these temptations to move to iphone again.
Should I move back to the iPhone?
no, galaxy s2 is the best !xD
my battery is very good so i don't care just try some kernels or roms
iPhone 4s is much better than SGS2 IMO.
Better size, better display (imo SAMOLED+'s colours are too cartoony), better resolution, better camera, better audio, much better battery and a much faster processor.
Also, iOS has proper dual core optimizations and actually makes good use of the A5 chip, wheras with SGS2, you'll have to wait for a stable ICS rom comes out.
Despite the negativity of the i4s, I personally think it'll be one of the most underrated phones this year.
But that's just my opinion.
My s2 often gives me 16+ hrs of heavy usage (my phone is from the first batch) my other half got a white s2 a few weeks ago and he has dreadful battery life. Both same firmware ect. Although mine is made in korea both battery and handset. His is made in china. Different colour mainboards too. Mines blue his is green.
Sent from my GT-I9100 using XDA App
Well just to make the point clear, you will never get your sgs 2 to have as much of a battery life as the IP4S. iOS is simply much better at handling battery life than android.
Now it depends on what you want really. Do you value battery life over functionality/choice?
Personally what do you expect of a phone with a dual core 1.2ghz processor? If you expect 12 hrs now that is simply idiocy. You have a laptop that can do that? I don't cuz mine lasts 2 hrs with heavy usage. I haven't read of any laptop being able to last 12 hrs of heavy usage either. No I don't expect a laptop to have a battery life like that either. Now this is a phone with a processor better than most if not all netbooks, it is not going to have a 8hr+ battery life with heavy usage just like a laptop.
I feel your pain with battery life. Also, screen burn in isshowing its face on mine too. But threw iphone is waaaaaay too locked down to make it an easy choice.
Sounds like you dont have things set up correctly to me or your using some resource hogging apps.
Im on wifi all day, send between 40-70 sms a day, couple of phone calls, tweetdeck auto updating, around 20mins of music (well, podcast, but it is an audio file), auto updating of all my apps enabled in the market and the obvious hour or so web browsing and 10mins or so of minecraft when I sneak off for a break in the toilets and I get home with around 30%
Dont forget, your also comparing a closed up OS which has been around for a fair old while to an open one which is still reasonably new which each phone manufacturer has his way with before chucking the phones out
Im not going to fight the android corner as you admitted yourself you are 'looking for reasons to not move back'. Which sounds as though you have already made up your mind.
If you want to go get a shiny fragile phone with a half eaten apple on it by all means do Glad you've at least tried Android though, your light years ahead of 90% of Iphone owners who live around here lol.
must be something thats killing your battery in the background. I quite easily get over a day and between 5-6 hours screen on time. Longest ive had was 6hr 38 mins screen on.
Download better battery stats and see whats running in the background.
Lawl you all are missing a very important statement in his post. "HEAVY USAGE"
What is heavy usage? Web browsing, playing a 3d game, watching a video, recording a video, taking pictures, etc. So of course he is going to get 6-7hrs of battery life.
I agree with the above post. find out whats draining your battery. Shouldn't be that low...unless you are just sitting on your sofa browsing constantly because your so excited about a new phone like i was.
Also you can buy a dock charger and extra batteries set for cheap together (ankhers set) so you never have to plug your phone into a charger again
But it sounds like you have alot of money to burn...then why not...being in a locked system isnt so bad when your willing to just buy every app and media at premium prices and your happy with the interface
Thanks for the quick reply guys, and yes, i m loving my galaxy s2 as i mentioned earlier. And yes, im a heavy user, around 100 texts, playing 3d games (sandstorm, brothers in arms etc). I barely keep wifi on as i haf 6gb of data which is almost unlimited. and im getting 7 hrs, which apparently seems to be good. If thats the case then I have nothing to complain about...
And in terms of money, lol i dont have any... its just i could get an iphone if i sold this one... no way i could afford to keep both!
Stick to the SGS2 and wait for the SGS3 till then.
Hmm, If were I, I would like the iPhone 4S. The iOS 5's new feature iCloud and iMessenge really attracted me.
And can get many apps for it:
http://www.enolsoft.com/blog/best-free-iphone-4s-apps/
SGS2! iPhone4S is inferior in many many ways. It's a ****ty phone.
/ownership bias
u should wait untill the ICS rom is out. that should improve the battery life, because it will be customized to a dual core processor.
Iphone 4S is quite a good phone, but I'm personally against Apple's politics regarding software and price. I don't want Itunes, no format support like FLAC or MKV, no Flash. Also Android has more customization abilities in themes and menues.
I like the big screen and weight on the GS2. Well, the battery life could be better on SGS 2. But there's a Samsung 2000mah battery available at the moment and you can easily replace the battery.
I have been in the same boat in fact I have swapped my Iphone 4 for a SGS2 three times, until finally I realise that the SGS2 really is a SuperPhone.
The reason you will find battery life not quite as good as the Iphone4, is basically down to the fact the Iphone is not actually doing a lot.
I waited until iOs5 before swapping back to this truly, greatest phone since the HD2, iOs5 really is a disappointment to say the least, you get a pull down bar that kinda copies Android to a point, but fails in the fact with its Iphone basic-ness yet again, the weather links to the most basic of weather apps, the notification animations appear at the top all very nicely, but the top bar doesn't state that notifications are listed within, they tried to match the Androids version but in true Iphone style, didn't leave in the design to allow users to feel its their notifications.
One thing you will never get away from even jailbroken is the fact you are not free to choose...you will never own your Iphone, it owns you, Android on the other hand is the opposite and with the SGS2, its power and freedom is far more adaptable than the iphone4.
As well as the nook I also have an asus transformer and a bkackberry Playbook.
The Nook and the transformer seem to have similar standby time but I realised today that the Playbook knocks spots of of both of them. The playbook has been sat on the table in the living room for a good few days and it's been just in normal stanby with wifi still on (not sure if it shuts off when it sleeps). I picked it up expecting it to be flat only to find that it still had 30% power left!!! The nook just couldn’t do that length of time I'm sure, if I leave it it may last 2 days I guess.
What sort of standby time are you all getting? Do you set wifi to disconnect when it sleeps?
Woah, that's definitely NOT the standby time I get. I've set my Nook Tablet aside for a full day without use and the most I've seen it drop is 1-2% of its battery life. In fact, I haven't even charged it the past 1+ week and it's still around 70% (and that's with minor reading inbetween at low screen brightness and WIFI off).
I'm pretty sure I could set my Nook Tablet without touching it for a week straight and it'd still have a majority of its battery life like a champ.
The only thing I can possibly think of that's helping is my use of Juice Defender I have running in the background, but its main battery saving function usually involve s around minimizing WIFI activation as far as I can tell, and that is somewhat moot if I have it off.
yea I wish my NT could sit around not charging that long but really no complaints here. I get a good day out of it

Well from what little I know about the two tablets they both have the same base chipset and very similar screens so Nook 'should' be able to do the same as the Playbook so I'm definitely going to look into it further
well we need to find out what the secret is lol
I get days out of my NT when I don't use it, though even when I do use it I barely seem to put a dent in the battery percentage.
I'm so used to my old laptop and many phones over the years that I had to try my best to squeeze a day out of, that this thing just blows my mind sometimes.

With my transformer it'sbecause eit dien'st sleep when connected to the dock, it's a known issue and if I got off my backside and contacted Asus they'd RMA the dock and fix it. If I disconnect the dock form the screen I get days out fo the screen even if I do use it a bit
Nook just doesn't seem to compare. Not yet anyway...
I'm on my fourth day, without a recharge. I haven't plugged it into anything since I started using ADBWireless. I can't estimate the screen-on time accurately, but I've read over 200 pages of memoranda and have been messing with my widgets and layout a fair amount. It's at 36% right now. I don't plan to plug it in until it dies (for science!).
anyone have any thoughts on this? I'm getting poor battery life as well. I'm running current widget and when I come out of idle there is quite a bit of current being drawn (200ma).
I'm rooted running go launcher.
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).
The nook charger is a 1.8amp charger

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).

Ahh. That explains a lot. Looks like I should pack that in my bag rather than my Moto charger. I wonder if it'll charge my phone faster?
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...
Maybe someone can give some input about the following:
At work we have an iPad 1 and I've been monitoring it's battry drain in standby last week:
Full 6 days standby, with Wifi ON and not used in meantime:
battery went from 58% to 54%.
With my prime I get 2-4% during 1 night!
And that's even with Wifi turned OFF and docked (auto airplane mode app)
The dock looses about 1-2% each night
Why does the iPad have such crazy battery life in standby mode + wifi on? Is it all about good written software (iOS, drivers and apps)? Or is it hardware related? Or both?
In other words: will it ever be possible for an Android tablet to get such great standby time when ICS get more mature? Or is it already possible on other devices and lays the problem within hardware/drivers from Asus?
I really dislike having to use auto airplane mode, because I sometimes have to wait 5-10 second for wifi to get connected and ready. But with wifi turned on, the standby drain is even greater.
This didn't need its own thread. Should have posted it here.

you might have some wakelocks

use better batter stats to see what's causing your issue. I get great standby battery life + wifi on. plus 2% drain isn't bad at all in one night. my prime can easily get over 20hrs. on a charge with off and on usage. I get about 10hrs. or so with moderate to heavy usage. about 9hrs. real heavy usage. battery life dependent on several factors. as far as standby goes, like the other poster said, you are experiencing system or partial wakelocks. cutting down the frequency of updates can help or solve this. everytime you asleep and device goes off from a notification, its woke up out of sleep. then eventually goes back to sleep. this is a repeated cycle which causes extra battery drain during sleep. because device never gets a chance to sleep long because its always being disturbed by notifications constantly going off.

I know that my 2% idle drain is quite good regarding to current prime and firmware/drivers, but how can a 2% drain in 8-10 hours be good when the iPad drains only 4% in 6 days (that's 144 hours!!) ?
The difference is HUGE, so that's why I wondered if it's bad coding in Android, drivers, Apps or maybe the used hardware that consumes just quite a lot more than iPad. Is 2% also common with other andoid tablets?
And if it's really software related: can and will it ever be fixed or at least reduced?
Edit:
When in standby my prime is always in "deep sleep" and I don't see any interuptions. But I sure will try better battery app.
Then again: this is all with wifi off and iPad had default settings with wifi on and still consumes way less
My ipad 1 have a great standby time too, comparing it to my Prime, My iphone 3gs has great standby time to comparing to my Galaxy Note. BUT it is too bad I didn't buy those stuff to be there looking pretty, I bought them to be able to USE them. If my stuff stays on standby a lot of time, seems like I really don't need it.
On my home network, I get about .3%/hour battery use on standby. I have wifi configured to stay on when the screen is off, and I have a number of apps that synchronize in the background (gReader, TweetCaster, email (X2 accounts), Gmail, a tasks app, calendar, etc.).
The worst standby that I get is on my work network, where I get between .5%/hour and 1%/hour. I believe it's something to do with the router at work, which also causes problems with my HP Envy 14 notebook. Note that the difference in standby life is absolutely consistent and quantifiable.
At .3%/hour, my Prime would last for 333 hours. At .5%/hour, my Prime would last for 200 hours. Worst case scenario is that at 1%/hour, my Prime would last for 100 hours.
Quite honestly, I'll take a Prime that lasts between 100 and 333 hours on standby while running all sorts of useful background tasks over an iPad that last for however long while running few if any background tasks. My Prime is more USEFUL to me that way.
And, even if the iPad runs the same sorts of background tasks that I've described here, 100 to 333 hours of standby is perfectly fine. Is it as good as an iPad? Clearly, not, in this case. But even so, it's also a distinction without much meaning.
why is it that all these people make ****ing mac/ios based threads?
serious if you don't like what you have bought... G T F O
p.s. stop the trolls ok? ipad ****ing sucks and what you claim is total bull**** anyway. 4% in 6days with wifi on dreams are there to be made.
fact: use that ****ty ipad turn on wifi and use it for 6-8 hours.
OMFG WHAT JUST HAPPEND? oh gaws....
now try with the prime
profit.
<edit>the topic of your thread... serious... your talking about 2 devices not even the actual software.. dip****</edit>

Even if your using really clear, hard to see, mono filament, trolling is still trolling.

Its not an issue with Android because I can get 2 months on standby with my Nook Color running CM7. The tf201's standby time is likely due to things on the kernel level rather than Android.

I was just going to post how crazy my nook color is with power consumption, but thats not the same level of processor that the Prime has.
Not sure if this has already been said? But iOS battery% behave very different than Android battery%. I noticed that when i got my first android device after using an ipod touch for a while. (that was a while ago so maybe things changed with iOS 5x never used that)
The iOS% will kinda adapt to your usage. If you play a 3d game on high brightness the battery% will go down pretty fast, but if you go back to standby they go up again. After some hour of gaming you can be down to 60% but after another one in standby it could go up to 80% again...
In general it feels to me like they lie "a bit". It could very well be that if you used said ipad it would drop to like 30% after 5mins of using. I found the way it behaves very annoying. But as I said that was on my ipod touch, maybe the ipad is different.
Android battery% are much more "direct" but also more accurate in my opinion. With my ipod I never knew how much juice is really left. With my phone or tablet now i know exactly what i can do until it shuts down.
That being said, i'm pretty sure there's still alot of room for improvement with the prime. The software is just an early version basically - all they did up to now is make sure everything works more or less and that its stable for most people. I'm confident the next patch will make things alot better in many aspects.
And i wonder how my prime will be like in half a year with a perfect custom rom

That's true, but isn't Teg3 and the new Pad line supposed to be fairly efficient?
With the majority of my time spent at the lowest clocks, the drain I get does seem kind of ridiculous. That opinion stated, here's another: the battery-life on the Prime is still fantastic. I can almost push it an entire work-week on one charge so long as I'm not trying to game or anything, that's a pretty stout stand-by for most electronics. The OG iPad just happens to be so underwhelmingly powerful that its standby is much greater.
I personally believe that to coax away the random locks/reboots they raised the voltage values so that we're drawing unneeded power; however, I for some reason have not ventured into my Prime to see what they have the values set to so I have nothing to back this up. Just a guess.

If its truly in standby/sleep then the processor should be essentially off. In the case of the Nook Color the primary CPU can power off entirely.
The issue is the dock, when mines not docked it can idle for over 60 days (according to battery widget app) and when it's docked I lose over 10% a night or more

The dock is not the issue, neither is Android and neither is the processor. It comes down to what apps you're running, live wallpapers, radios, etc. Or just good ol' fashioned faulty units...or poorly built ROMs/kernels.
I'm running stock, rooted .15 with performance mode on always. When I wake up in the morning, I unplug my docked Prime before I go to work. When I get home 10 hours later...dock is at 100% and Prime at 99%. That's with dock connected, performance mode, bluetooth wifi and GPS all ON and no "battery saving" apps of any kind running. And that's been consistent for the last two weeks. I DO, however, kill all apps in the recent apps menu. I don't force stop them or anything, just open up the recent menu and swipe them away.
The only time I've gotten battery drain was when I left an N64 emu, an SNES emu, Sixaxis and two other games running in the background. That ate about 10% battery or so in 10 hours.
I left my prime unplugged for 8 hours, wifi on, and it was at 99%. So I don't know what the OP is talking about.
Additionally, iPad doesn't have a good clue as to what real multi-tasking is like, and therefore doesn't update as much because it doesn't have services running in the background.
Android does have services running in the background. Give and take. You want your data always refreshed? What intervals? etc.
That's all configurable, so you really decide how long your battery lasts.
Advice to OP: Read more, get smarter, post less dumb crap.
