Your problem might be using the laptop as a power source. If you use the wall charger it should completely charge from 0 to 100 in about 4hrs

thanx for ur replay
Can u tell ur nook color how long keeps the charge when i am watching the vedio every 3 minuts one parcent came down i mean if i watch vedio when all other comunication is off like wifi bluthuth and other comunication so if i continue watching vedio it will keep its charge 300 mints so what u friends think ? I think my battry have problem becuse i bought the nook color from my friend.
If my battry have problem i think i cant find it in afghanistan thanx friends

1. use the wall charger, it charges real fast. charging from a laptop with the included cable is not a good idea.
2. There are a lot of things you can do to improve battery life, most of which will require rooting and flashing a different ROM besides stock, just so you can get to the settings that make a difference. 5 hours of battery life on a stock NC playing videos is probably about right. I get 10+ hours of video out of mine with extensive tinkering. Far and away the biggest factor is the screen brightness, and beyond that, how bright, on average, is the video. I watch movies with brightness about 9-11%.

thanx mr 72 for replay
i am using cm7 custom rom
So what should i do to do beetter for battry life i am watching vedio in 0% brightness plz help i want to see vedio a bout 10 hours if poossibl thanx

Battery life will be affected by any radios, screen brightness, and CPU clock speed. The nook is not meant be charged over USB, but as you can see, it is possible. If you're looking to get a ten hours battery life, and you've purchased and rooted the wrong tablet. Id say nook color can get anywhere from 5-7 hours based on the above factors.

Mine takes 4 hours but my nook needs to be off to charge. If it is left on even with the screen off and saying charging, the battery is actually going down. Kinda stupid but whatever this thing is cheap greatness lol

NC can certainly get 10+ hours of battery life under normal use, and up to 17+ hours in my experience if you are using apps that require no wifi, low CPU and can tolerate low brightness settings.
Follow the guide in my sig.

I suppose under the correct settings you could. Is this including sleep time or solely screen on?

That's "on" time.
17+ hours of actively reading ebooks (Moon+ reader in my case, black text on off-white background, no wifi enabled [was on a plane], brightness around 10-15%)
10+ hours of actively watching movies (MX Video Player, movie format varies from 720P to 480P DVDrip h264 and xvids, also no wifi, on a plane)
I say "+" because I quit using the NC and there was remaining battery, so I don't know how long it would have run if I let it run to zero. Check out my guide (in my sig) to see how I set mine up. There are no settings that compromise performance or utility.

I find charge time can vary pretty greatly. Last night i didn't get a full charge with the same settings that I had the night before.. aside from updating to a new nightly. Generally I can charge the device in less than 5 hours if the wifi is off and nothing is running.

I'm going to piggyback this forum as I have been searching over 40 min and this looks closest. Sorry ahead of time.
I also found it takes forever to chafe my nook. I have a droid raze and ourchase local for it so I'm using in my nook to shutbdown the wifi from 1am to 6.am. hmm I may change that to. 12:69 am. It will help with my issue but I still have the the following request.
Wifi seems to be eating up battery life. Does anyone know of a program that will auto off wifi if not used for say at min?
Also for other readers: I found a simple free program called connections (for the bionic connectivity issues) I use it on the nook when there seems to be an issue. I have a shortcut in app launcher so its avail in any program.
Any feedback welcome.

No, but if you leave the defaults, then wifi should be off while sleeping.
Or you can use the status bar pull-down in CM7 to turn it off when you are not using it.
However, I find that it doesn't make a huge difference.

I am using Juice Defender Ultimate on my NC running rooted B&N 1.4.1 for exactly this purpose, and it is working well. I also tried Green Power, but had problems with it.
JD is definitely overkill, since it's meant for device with more radios. You could also use Tasker and set it up to turn off wifi when the screen goes off.

I looked at tasked but thought it would be overkill since I already have local set to turn off at 1am.
I will check out jd as I may use on my raze as well.

Thanks, I did not realize the default for cm7 was off during sleep. I will test but I can swear upon wake it would be found I forgot and left the wifi on. I will check that setting.

Battery life in standby?

I did a little experiment with battery life, particularly in standby mode.
Wifi is on, and the weather/clock widget updates every 2 or 4 hours.
After 24 hours not using it at all, battery life went down to about 94%.
On an ipad2, after 24 hours, it is at 99%.
On, ipad2, most notifications if not all are turned off. Could this be the reason for the discrepancy? Any ideas to make it better? Should I have weather update 1 every 24 hours and update manually as needed?
I notice I cannot set the update interval for mail? Is it because it is push and not pull?

Id be greatful with that kind of battery life. Honestly.

really? standby time is important to me. I go through spurts of not using the tablet but I don't want to have to keep the tablet plugged in.Turning it off means I have to wait for boot up to use it real quickly.

I have it turn my wifi off while screen off and with build.prop tweaks I get 7 days b4 I have to charge... Or... Get juice defender in market and it will handle the wifi and syncing to give you much greater battery life.

It lost 6% in 24 hours. That means it will take over 16 days to drain. I doubt many users will see this as a problem.
I guess you could uninstall any widgets you have and keep it in power saving mode. Turn off wifi. Check the apps section in the settings menu and see which ones are running in the background and uninstall them.
Otherwise, buy an ipad if you want ipad specs.

I'm at 87% at 2 days and 10 hours right now. I have FW .29 and SeanZ's tweaked build.prop. I'm happy with it personally.

Personally I've been pretty thrilled with my battery life. I've never had a device before that would still be at 99% after four-five hours on standby tweaks or not - and the biggest tweak I've done is disabling weather (I've gotta save something for my phone to do).

Get the keyboard and use it like a docking station.
The tablet slips in it pretty easily.

I'm not really happy with the standby time so when I'm not around or sleeping I shut it down.

Probably shutting down WiFi is the most important battery saver. Either by hand or with an app.
edit: Except apps producing wakelocks, of cource. Better Battery Stats helps.

what is this tweaked build.prop and where do I get it? Is root required?

+1 this. I have to say, I was a bit skeptical before I updated my build.prop file. But when I did, I noticed an immediate speed boost and much much much better batter performance.

Massive battery drain when in sleep mode

I just posted a very positive review of the TF300 today and just got back home after being at work for ten hours. I left the dock and tablet at over 95%, but just got home to find the dock at 0% and the tablet at 46%. This is obviously awful and makes the Toshiba Excite seem great in comparison.
Settings:
MobileDock battery saving mode is on
Disconnect network during sleep is on
Set to balanced mode
Set to turn off after two minutes
I turned the tablet off before I closed to the dock and when just opened the display was off.
The only two listings are 64% for screen and 36% for idle.
Is this normal? If so, this is abnormal.

weird, i don't recall that ever happening to me... try it again, charge it to %100 and leave it on sleep mode at night and check in the morning if the problem persists. if so you may have a defective unit so return it using your warranty.

Another thing I notice is at least in Dolphin, the browser crashes when trying to view Flash video in full screen. I have never had that happen with any tablet or phone before. Weird. Like always, set in desktop mode for user agent.
Edit: Must have been a fluke since a restart fixed it. need to charge now anyway to see if I get the drain again.

I noticed if you turn off the tablet then dock it, the tablet will turn back on. But have never noticed a battery loss that significant. So be sure to dock the tablet first then power down the tablet.

I've had mine for over a month now. Had something similar happen one time. Best I could figure out was ICS did not properly shut down a game I had running. I assume it was just a rare random occurence.

You should check out the new dolphin beta that just came out today, supposedly wickedly fast. It is here: http://dolphin-browser.com/2012/06/dolphin-browser-is-the-fastest-html5-mobile-browser-try-out-our-dolphin-engine-in-beta/

It did it again last night:
Made sure no apps were pushing data and turned notifications off for all apps
Restarted the device and opened no apps
Five minutes later I put the device to sleep (closed it).
The display was off
Result: This morning the dock was dead and the tablet was at 65%. This was after only six and a half hours (I usually do not sleep much).
The only activity was the display at 84% and idle at 16%. I checked a few times through the seam of where the KB and tablet are closed and the display was off for thirty minutes before went to sleep. I then had to get up a few hours later to let my dog out and the display was still off.
The last time I had problems like this was the infamous A500 problems where the display would come on, stay on and the device would die. In this case, the display is not coming on, yet the display is eating the battery and the device is warm (dock and tablet). The A500 was obvious, since the display was on.
Folks, I just want something to work correctly. My HTC View loses 5% over three days and my iPad 3 wifi loses 1%.
How can the display be off, yet the device be warm and the battery log show the display is the majority of the usage? No doubt the display was off (at least at the times I checked).

The display is the majority of the usage period. When in normal yesterday with 100% brightness the display used 99% of my battery use. That extra 1% was for the dozen or so apps I had used. The fact that the idle hit that high is a good thing but something else may be affecting it.
Have you tried disconnecting the tablet from the dock and then letting it sleep?

That is my next test, but if they can not behave together, the value of having the TF300 diminishes. I would need to keep them is need to leave seperate, since defeats the function for me.
I see the point in at least testing to see if the dock is the issue. Could be a bum unit, but also could be the dock does not like cards being left in.

My tf300t works amazingly without any battery problems.. I'm a very heavy user of it. also try getting that app that monitors background/network process...forgot name if someone could help. Also the dock could be at fault since the dock automatically turns on the tf300t same as if you would charge it with the cable it turns it on while charging.
I believe the build.prop mod contains something about deep sleep that might help ya but if ur in the 30 days just replace it why bother when u might have an intermittent defective unit . problems that can happen once in a while might be a pain in the ass later on.
I do not regret choosing this tablet over everything else on the market it works great and it is replacing a laptop for me.

I've had no problems with the battery on my tf300. It lasts all day when I use it (and because it's new I'm giving it some heavy use) and when I do need to charge it it only takes an hour or two. Maybe because you just close it something doesn't shut off. I don't own the dock.... Yet but when I do I think the extra life out of that will be awesome. On a second thought I was also wondering what would happen if you just left it on the charger overnight? I put my phone in a dock to make it my alarm clock every night with no problems. Is a tablets battery different that it wouldn't be healthy for it to be left on the charger? Or does it needs to fully drain then charge to 100%?

I agree it is nice system so hope I figure it out. My Office Max dock should be in soon, so have to return this dock anyway. OM was $100 (sale) and BB is $150. BB matched the OM price on the tablet ($350), but the dock was not in stock at OM. Ended up ordering one online from them.

I normally do leave it on charger but it is problematic when away from home, since uses as much battery as when on. Not to mention it can not be doing the batteries any good.

For process of elimination I tested the battery drain with the sdxc card out of the dock. This seems to help, but still have over 20% battery drain (a lot less, but still bad).
Next step is the tablet on its own and then I will test with my newer dock, since just came in from Office Max (need to return the $150 one to Best Buy). Hoping the dock was the issue since if the dock and tablet can not behave together, I will return them and not dwell on it anymore.
Hoping the drain is gone so can keep Having the sd card, micro sd and 32gb internal solves all my gaming and media needs, but need the batteries to not bleed out when should be asleep (not practical to travel with- as is).

Aftera few full cycles i notice battery depletion much slower also I keep the tablet in balance and performance when gaming things like nova 3 and tegra stuff etc. And around 25-30% brightness is more than enough indoor . My battery last me all day on 1 charge including the dock wich it charges arund 60-65% extra battery. This are just estimates through my experience with it not concrete data.
Sent from my ASUS Transformer Pad TF300T using XDA Premium HD app

I have 40 more days to return the tablet with Best Buy, so want to see what the issue may be and avoid resinstalling everything and setting up if can avoid it.
I really like the tablet and also that it is not clocked higher (better for heat and battery). It plays N64, PSX and MAME Reloaded fine. Ditto for Flash and hidef video content. Touch response is as good as my iPad 3 and former Toshiba Excite.
Also, for $350 the tablet is REALLY nice. Not wanting to paying much more, since already have a 64gb iPad 3 (2X the cost of the Asus). I mainly use Android tabs for Flash sites that do not work on the iPad (Amazon Prime is example) and game emulators. Heck, even books and comics look sweet on the 300
Along with the dock, the 300 makes a GREAT mini-system for games and media
Besides, I am not a fan of 1920X1200 displays being pushed by the Tegra 3 and no gpu modification. The chips sweet spot is 1280X800. My iPad 3 rocks with hi res but has a bigger gpu to support it.
Update: Even with the new dock the batteries are sucking dry. 20% gone in a little over an hour. It is like the display is on, based on the drain.
Will test tonight with just tablet, since same result with two docks.

I hate to ask this because it's seems so obvious & condescending - but what have you installed? Did you try doing a factory reset? I've had 5 android phones and few times I've loaded some obscure piece of software that killed the battery. I've even loaded ROMs that sucked the battery down with no mods.
I ask because I just got my TF300 yesterday and played with it all night without charging it. I did the 4.0.30 OTA update as soon as it booted up. I let the keyboard completely die and left the tablet (undocked) this morning with 56% on it. I didn't put either on the charger because I want to see roughly how long it will run without doing so. I'm hoping I have no problems such as yours, but I'm watching this thread closely.

Ok, so you know what my usage is - Like I said, I left this morning (6:30) with the keyboard dock battery dead & the tablet battery at 56%. I got home this evening (5:00) and the tablet was at 53%.
Luckily I'm not seeing the problem you are (though I haven't tried to charge the keyboard yet), but at least you have a warranty to fall back on.

Battery consumption Tablet/Dock Tips for Better battery life.

So I thought of making a thread on your experiences with the battery consumption ratio depending on use etc. My main reason of doing this is because I suspect my dock has a bad battery and I would like to see you guys experience with your tablet/dock combo.
Noticed much difference between power saving, balanced and performance mode?
Processor wise I know each has a rating of 1ghz,1.1ghz and 1.2ghz. I dont see how this would make a big impact in battery life. Now I dont know if these also regulate anything else than the cpu frequency as to make it a noticeable thing.
Whats's the ratio of your Tablet/dock charging? ( what I mean is once your tablet reaches 70% and dock kicks in to charge how much battery would it be left on the dock after tablet reaches 90% wich is point where dock stops charging..
If I leave it charging without using it my dock is left with about 55% battery.
Last night I left the tablet at 52% and the dock fully charged so I left the tablet in sleep mode and charging with the dock. when I come to check on it battery was at 90% dock at 25% . I'm curious if the scaling is alright or am I having a performance loss.
I noticed the dock discharging while it is not supplying battery to the table ( By the time my tablet reaches 70% for the dock to kick in to charge the dock has gone down to 98%).
The biggest power drain is definitely screen brightness though this IPS display seems really nice indoors no more than 20% brightness seems to be needed.
I would also like it if we could post your advice for a better battery life on these wonderful tablets to later on make a recollection of all and post them on 2nd Post
I'll try to keep up and be adding em there.
Well this is what I got in my head so far if your willing to post any other experiences or advice I would gladly appreciate it.
I'm somewhat of a complete noob, I'm here to learn and share my experience with other users.

Battery life tips.
1. If distance is not an issue use bluetooth tethering instead of wifi tethering. It consumes less battery on both devices.
2.Try using the brightness level you need not max it out like most people do.
3.If your an active user on wi-fi, turn on setting for wifi not go to sleep. Every time tablet goes to sleep mode it would be disabling and enabling Wi-fi wich in many devices this has proven to consume more battery than keeping an active connection.
This list will keep growing as more tips are posted.

This is a well timed thread, since I have been having battery issues and the tablet on its own is not the problem. For whatever reason, the dock and tablet together equals massive battery drain in sleep mode, where the tablet on its own only uses one percentage point over night. The majority of both batteries are drained if docked in sleep mode.
I charged the dock to full on its own and unplugged it and will check this evening to see status.
Tablet on own =
Tablet docked = :silly:

Well when I am not using my tablet for sleeping or working I usually just shut it down. Doesn't make sense to me to just always have it on. I'm usually away from it for long periods of time and it doesn't take long to boot up. Plus if I go to use it later in the day or a few days later I'm not looking for my charger because I fully charged it before shutting it down. I keep a laptop/computer mentality with it where if I'm not using it turn it off.

Well as I said before on ur thread I would replace it in ur case though a corrupted firmware could cause that. On my g2x a bad Install once drained my battery like crazy so might want to try that. I think u need to unlock though

I do not think there is any firmware in the dock itself. I think it is a pure slave device that is controlled by the tablet. The tablet on own does not have a drain issue, but when docked they do together.
On my second dock now with same result.
The tablet and dock together ironically seems to have the same battery life in sleep mode as my Q2670 Lenovo 14" gaming laptop = bad I was hoping the dock and tablet combo would be just as efficient as an Android tablet on own and avoid having to cold start when using it (that seems so Windows to me).

Well in my case I am replacing a netbook.
I use it for a lot of things like Torrenting, college notebook,games, media,internet browsing etc. I give it its full use.

Asus already knows about this problems. Its due to bad software in the keyboard dock (yes there is software for it/ only Asus can access it.) Its actually B.S. the only fix is to send dock to Asus and pay shipping urself. And they'll fix and send back. Prob about a month later
Or you can use the tweeked build.prob like I did. Shuck will allow deep sleep while docked.
Deep sleep = no battory drain
Just be careful with changing build.prob
read 5 times fully can't go wrong lol

Are there docks that do not have the problem that can be identified? This seems a silly miss by Asus.
Both docks I got from two retailers have the issue.
Also, do you need root? Any guide to fixing and links documenting the problem are appreciated.

I'm not sure but I think the docks only work as suppossed to on. 17 firmware. That's my best guess. Just look under development section. Only post by seanzscreams can't miss it for tweaked build prop.
Believe u need root. Or process alot easier if you have it. Just be careful if you don't follow instructions exactly can brick. But if you do everything which isn't much and not hard at all even for a noob

I'm not sure but I think the docks only work as suppossed to on. 17 firmware. That's my best guess. Just look under development section. Only post by seanzscreams can't miss it for tweaked build prop.
Believe u need root. Or process alot easier if you have it. Just be careful if you don't follow instructions exactly can brick. But if you do everything which isn't much and not hard at all even for a noob

Separated, my tablet consumes 1% in ten hours and the dock about the same when in sleep mode. When together over the same time, they collectively drain almost 70%. The dock is dead and the tablet with the rest.

Rushless is right... I also see more drain now with new firmware, when the tablet is docked.... Seems like a bug

No kitties here. As stated, they both work fine on their own and have had two docks. Testing another 300 yielded the same result.
The problem is the two pieces together. I think the sleep mode is borked when docked and bleeding power at a non user level.

So... back to battery saving tips.
I get scary long battery life by just reducing screen brightness. Would like to mess with build.prop but haven't yet. I know there is replace n go's out there but I want to find out which settings do what specifically. Still looking for more information on the subject.

I give this about 8-9 hours daily on 1 charge of tab\ dock.

My battery life:
Docked and using fairly heavy- about ten hours
Docked and in sleep mode- Both batteries dead in 14 hours
Undocked and using fairly heavy about seven hours
Undocked for over 12 hours tablet = 98% Another time was 99%
Undocked, the dock went 24 hours = "100"%
Ironically, my problem is with the device docked in sleep mode. Two docks, two tablets- same issue. No info showing an app or media task causing it, so lower level bios issue. Both tabs newest firmware, no clue what the docks are/were. Have one each now.

Those having problems, check "Settings/Asus Customised Setting/Mobile Dock Battery Saving Mode"
Enable it and see if it matters

CM10 battery life

I have had CM10 on my Nook HD for a couple of days now and I am disappointed by the battery life so far. To be honest, it is more a question of being impressed with the battery life on stock ROM than the other way around. Because coming from Nook Color, I was quite impressed by the battery life on Nook HD. In standby, it would go for a week without charging. With moderate usage, it would easily do a couple of days or 3 days even. But with CM10, standby sucks up battery juice like crazy. Overnight I lost about 40% charge. So I am seeing Nook Color battery life on my Nook HD.
This would probably keep me from using it as my daily driver. Since CM10 is so much more useful, I would probably boot to it when I need to do browsing and checking RSS feeds etc. But I think I would have to go back to stock for reading.
Is it the same experience with battery life for others? Thanks.

On stock it shut wifi off when it sleeps, on CM10 you have to go to wifi settings and edit the settings to do the same because it's set to not shut off wifi when sleeping.

I have generally found this true on all my nook devices, Color, Tablet, HD, and HD+. CM10 can just not match stock on battery life.
But I like CM10 so just charge every day.

That might just be the trick, as I shut off wifi this morning in CM10 at 63% charge and the battery is still holding up at 60% after some four hours.
More testing will reveal if it becomes usable with wifi shutoff.
But Nook Color using CM7.2 had insane battery life. Even better than stock -- way better. I don't know how the developers did it but they put BN developers to shame by getting that good battery life out of that device.

There was a problem with deep sleep on the 12/28 CM10 release. Temporarily reverted to the earlier kernel (B&N binary) which helps some apparently.

i've used 12/19 only and found battery life to be pretty bad when in sleep mode. even with wifi off it wasn't nearly as good on standby as stock/root is. but you do get lots of extra features so you gotta pick which is more important. better sleep or a more powerful tablet.

I am on the 12/29 Linaro build and after posting the original question, I took r1c47's advice and shutoff wifi when not in use. I've had good results since then. I did some reading in Kindle app but my battery was still at 40% from that original charge when I posted the first message here. I just put it up for charging again but I might stick with this build for a long time. I just shut off the wifi when I am reading which is most of the time.
The only (minor) problem is the lack of rotation even after checking the box in settings. And I have not tried playing music or videos so far. But otherwise this build is good for me.

The rotation issue is well known. Just hold the device vertical when you want to rotate and it will. And there are two rotation check boxes in settings. One in display and one in accessibility.

Found last night that I was missing the second check box in settings. Everything peachy now. Thanks much!

I confirm that the battery life is acceptable after turning the wifi off. Is there anyway to make it turn off wifi automatically, though?
thanks

Go to settings, wifi, menu, advanced and choose wifi to never be on with screen off.

I'm quite happy seeing over 2 days (sometimes little over 3) on CM10 12/31 build, shutting down wifi after 5 min inactivity and when off.
However I find it a pita to switch off and on wifi all the time when I resume operation on the device. Is it a known issue, or am I the only one facing this?
Thanks
