...4 hours of heavy usage (wifi connection and 3g on but idle)
Mid to periodical usage could reach 24h.
6th day of usage....
i think this is mediocre for me. please report your battery performance to compare.
Any tips to improve this?
I can get around 8-10 hours with heavy usage... constant music, etc.. and about 2-3 days with light-medium usage.

Hmm so i guess there is a problem with my device.
Great!, and how am i supposed to explain this to the service?
I get about 12 to 15 hours of heavy usage via web, text, and email. If i watch video it's less but I am pretty happy with the battery thus far.

I can only get around 7 hours of use.
I have a problem that if i even dont use it, the battery still drain. I got it full charged and theb unplug it. About 8 hours later, it went down to 50%.
Is there any problem with my device?

same here. i don't know how you guys are getting so much better battery life. i can barely last a day and i don't use it all that much. maybe 2-3 hrs of surfing the web over wifi (not even 3g). i even used setcpu to underclock to 200Mhz when screen is off.
Maybe it has something to do with the very first charge.
When i unboxed the battery was fully charged so i drained it and had it charged for 8 hours. maybe it needed to be charged prior first usage.

Is that 12-15 hours with the screen on? Because that's much more than I'm seeing.
I've done a few measurements just to get an idea of the battery life. They are just extrapolations based on a few hours of runtime for each so they are by no means exact, but my impression is that they give a decent view of real values nonetheless. The battery percentage indicator does not seem to be terribly non-linear.
Video playing (SD quality) with full brightness: 5.5 hours
Video playing (SD quality) with lowest brightness: 9.5 hours
Idle at homescreen with full brightness: 6 hours
Idle at homescreen with half brightness: 9 hours
Idle at homescreen with lowest brightness: 12 hours
Music playing in headphones (screen off): 90 hours
Can't believe how lazy reviewers seem to be, I haven't read a single one where they have properly measured battery life for things like playing movies or reading an ebook. It's all just subjective feelings (which are obviously very unreliable).
All in all I am pretty pleased with the battery life (but I've just had it for a few days). I especially like the fact that it's basically a normal Android phone just with a giant screen and battery. This obviously means that standby and music playing times are going to be excellent.
Edit: Those of you who think you're seeing bad battery life, what does the battery use thingy in settings say? Or is that not a good tool?
I read a post somewhere where the OP was getting horrible battery life and found out that the Gallery app was draining the battery.
The OP in that thread said even exiting the app did not kill it, and it kept draining the battery.
Perhaps you can look into this more. I never use the gallery app so maybe why this is why i get decent battery life?
Edit to add:
Here is the thread
http://forum.xda-developers.com/showthread.php?t=826472&highlight=gallery
If it's this post you're referring to it's by me . The Gallery application shows up under battery use though, so I'm pretty sure that's not it.
Are you sure it's really as much as 12-15 hours with the screen always on? If it were 9-10 hours with brightness at half it would around what I'm seeing I guess, but 12-15 is quite a lot more. Not that I'm disappointed, but if better is possible better is what I want

No not 12-15 hours with the screen always on.... I get 12-15 total... Screen on for usage, off for a while, back on to email and SMS ect...
Ah ok, then there's no discrepancy .
I got 10 hours from full to complete off. I was using it to watch streaming movies on 3g
for a couple of hours and then watch a movie off of the sd card and an episode of supernatural.
After that its just web and ebook reading. Its pretty good. Almost the same as my ipad.
I got a total of around 14 hrs plus with wifi and edge on, screen brightness at 20%, around 7 hrs of standby while i was asleep at night, with 4 hrs of heavy surfing, youtube etc. . . No calls though, only some sms and always on IM with nimbuzz logged in.
What i am seeing is with heavy usage i.e. Multiple apps running, wifi and edge on, i get anywhere between 5-7 hrs of battery life which i think is fair enough for a device this size which am constantly fiddling with.

Can someone please post,
Using the supplied mains charger, how long does it take to fully re-charge a drained Galaxy Tab?
As it is a large battery what sort of charging times to expect?

I've not used mine for that long, but the Battery Left app(which I found to be quite accurate on my N1) shows that for MY usage, I'll get about 25hrs.
I've got the auto dim turned off, and brightness at max. I mainly use mine for checking emails, txting, and a few games.
Nothing heavy.
I'd recomend the Battery Left app to you guys looking to find out your battery life. You DO have to "train" it though, which requires a 100%-0% run for you.
Guys,
does.anyone know, do we need to cycle the battery to give it the best performance?
Example, charge up the unit, then drain it completely and recharge it again? Like in the old days.
mine hasnt gone down much. I have it unplugged at 6am and at 4pm i still have about 75-80% batt left.
This is with about approx. 2 hrs of talk and 30mins of data usage and voice calls paired to my BT headset. My screen brightness is set to 40%

I once got up to 20 hours of moderate usage. But with heavy usage I get about 12 hours or more. I lose about 7% when watching an episode using flash....kinda sucks but I watch a lot of anime online. But I use this as my main phone too. Its replaced my nexus completely. though it was nice with my nexus cuz I could swap batteries. This is how I condition my battery. I let it get to about 2-5% then I recharge it. I don't let it get to zero cuz I heard you can damage the cell. sometimes I charge it to about 20% then I unplug it and drain it to 5% then back up to full. I just kinda switch it up. At first I was getting horrible battery life but ever since I started conditioning it this way I get great results.

Does anyone agree that the battery life for Samsung Focus is really short?
I use my phone to check emails, browse websites and listen to music during lunch, dinner and on the road. The total hands on time per day is roughly 2hrs. But if I only charge it overnight, not anytime else, it only last until right after dinner.
It unacceptably short comparing to my ex-phone, HTC Touch Pro2.
Anyone experiencing the same thing?
Who should take care of this issue? Samsung or Microsoft?
My phone on moderate use will last me 1.5-2 days but I usually charge it at the end of the night regardless. In the first couple of days I did notice that the battery would drain pretty fast but seemed to get better after that.
Mine will typically go from 7:30 a.m. to 9:00 p.m. or so while still having the battery indicator having something inside. That's with it being used all day as an mp3 player, triaging email, web surfing, and Twitter.
When you get a new phone the battery has to go through a couple of cycles charging for the phone to calibrate. Also, keep in mind things that drain battery: light theme, streaming, basically downloading massive amounts of data. Make you sure you discharge your battery to about 10% and fully charge your battery a couple of times. Try not to go below 10% not good for battery. Make sure you are using wall adapter ac to charge. Charging from a pc is very slow and generally doesn't fully charge unless you leave it plugged for a LONG time.
Light use I'd say 1.5 days
Moderate 1 full day
Heavy use 7-8 hours
With light use i get about 4 to 5 days, heavy use i get about a day or two. Check to see if you have location services (GPS) running, wifi, etc as the more parasitic things you can turn off the better the battery life of course.
Mine lasts all day for me. A long 16+ hour day with moderate usage leaves me at about 30-35% battery. I keep Wi-Fi turned off and bluetooth always on. Not bad for a smart phone. I've seen phones far worse than this (Sprint Epic anyone?).
My battery last abour 8 - 9 hours, and I'm running for a outlet by then. But I'm a heavy user. Bt headphones with the music playing, twitter constantly, facebook, text, email, IE..., pretty much all of those 8 - 9 hours.
I have just about everything that I can find turned on, and have been using my new toy as much as possible. With that, I'm having to charge about twice a day, which is roughly where I was at with my Tilt2. Your battery drainage really sounds like it's normal, and likely related entirely to how much crap you have turned on and running in the background. The biggest drainer of the battery in any phone is gonna be the radio, so if you want to improve battery life, turn off stuff that connects to the network and set your email/weather/tweets/facebook to refresh much less often. Select "as items arrive" for your hotmail and Gmail so that they push instead of pull. Check your basics first before trying to find a customer service rep to chew out.
I'm happy with my battery life. I just charge it every night like I have every phone Ive owned. I use my phones as my morning alarm clock. I have all location services active, and i activate WiFi when usable. At work I leave it plugged in to stream music and podcast.
Coming from Android and Droid Incredible, the Focus is awesome on battery. I have no problem lasting the full day. I charge my phone each night overnight.
It's a mixed bag for me. the first few days when I was just getting to know it, making calls and just goofing around with basic functionality the battery was lasting very long and things were looking great.
Once I started using the data and other apps, the battery drains very fast IMO. I mean play a 2D game for half an hour and I won’t make it through the day.
Right now I’m not digging it that if I’m out and about I feel like I need to avoid using the phone like I would like to.
I’m really looking forward to being able to do things like being able to easily disable 3g.
I'm most certainly happy with my battery life. After using a nexus one, xperia x10 and the galaxy s I have nothing to complain about with the focus....just lovin wp7 at the moment.

Games are always battery killers, especially on AMOLED screens that tend to get the best battery life with black interfaces, since they actually don't light the pixels up if they're supposed to be black.
Coming from an iPhone 4 i can't complain. Battery on that was amazing. The focus doesn't Last at long but I can't say im disappointed. It's actually better than expected.
It is normal for the battery to die after browsing the internet for about 3-4 hours?? Not happy about that.
Battery life
It depends on how the phone has been used. Screen is the biggest power drain, than the radio (3G data, WiFI, location services).
With all on and moderate usage (gaming for 30 mins, a few calls, and playing with the phone for an hour) I get about 12 -13 hours.
With all off and a few TXT and calls (about 10 -12) I get about 76 hours.
Not bad I guess.
This phone is better than iPhone 3GS.

I agree, I was loosing full battery within half a day with my normal usage for the first 4-6 days... Then after a while, now I can go for 2 days without charging under normal usage...
The battery life on this thing rocks!

I use my Focus heavily for reading texts off of PDFs and browse the internet using WiFi most of the day, and in my free times I listen to music so I use it quite heavily. Yesterday I ran it through my routine day and got about 14-15 hours of full operational time from 100% charge as I took off from my dormitory to university to 0% half-way back to my dorm. My only problem is the length of time it has to be plugged in to charge. Its pretty slow, but that may be because of the large battery capacity to begin with.
the battery life is just OK, hopefully like with other cellphone updates maybe battery life will be improved at least somewhat, we can hope....
I have two of these things. Mine I use a lot and while the battery lasts less than my old 3GS, I am getting used to it and end up keeping hooked up to a charger pretty often.
My wife's on the other hand is baffling. She hardly uses the thing, maybe a call every day or two. For a while there we were getting about 3 days from a charge and then it would still have around 30%-50% left.
Now in the last few days, it drains the battery completely overnight. And I mean completely its totally shut down and dead. That’s with wifi and Bluetooth off and virtually no usage. Not sure what is happening, but this really sucks as now she can’t count on the thing to just be a phone without needing to be babied.
Hoping to get some good feedback from those who have used the epic for a couple months or more. Now that you're probably using the device normally, as in not attached to it all the time, how is battery life? I've heard initial reports that it's not so good... Also, for those of you who have updated unofficially to Froyo, does the upgrade help with battery life? Can anyone comment how Epic's battery compares to EVO's?
Thanks.
I usually get about 9 hours in my stock battery and 6-7 on my cheap eBay ones. Overall idea say meh, its about on par with most other android devices. I'm running the stock dk28 leak as well with no battery tweaks or mangers of any sort.
Sent from my SPH-D700 using XDA App
On most of the DK28 roms I'm pulling a solid 10 hours with moderate use. For reference, If I leave the phone on standby all day in my house it's lasted 23 hours, if I recall correctly. Honestly that's pretty damn good for a smartphone.
EDIT: I don't use any battery-manager or powersaver either. Brightness = Auto, bluetooth/wifi/4g/gps = 1 is on at any given point in time usually. Google auto-sync = on as well as touiteur (twitter) and facebook notifications every 15 min.
I have been impressed by my battery life actually. I can't speak for the EVO(although maybe soon since my friend might give me his as a backup). I can usually get between 4-5 hours of play time(surfing, texting, apps, music, wireless tethering, movies, etc) The rest of the time it is usually idol. I usually charge it over night, unplug it around 7am, then plug it back in around 11pm. At 11pm, I usually have between 10- 30% battery left.
I just switched to a froyo ROM(bonsai, which is excellent) and so far the battery seems to be about the same. By lunchtime 12:30 it is usually between 70-80% and right now I am at 72% but I also had some extensive time testing the tethering feature.
To be honest, I had a blackberry, and the battery life was a little better, but the features were not nearly as good. It amazes me the battery these things get with that amazing samoled screen.
disclaimer: I do not play games outside of sudoku and spades, so my CPU does not really get challenged, which probably accounts for some battery savings. Oh and I use regular wallpapers, cause I don't really like the live wallpapers.
Im on 2.2.1,and I have to say I see a 40% increase in battery life compared to 2.1,and thats about 11-12 hours,no battery saving apps either,well except setcpu,which does help,but its set at 100mhz - 1ghz conservative.And I use it more now then when I got it,I havnt got tired of it at all.I have noticed the first 10% goes the fastest,and I have calibrated twice since moving to the ROM im on,and its the same in all,so if you get an Epic dont let that scare you.

I've had an Epic since a couple weeks after it was released and I think the battery is probably working the way they meant it to, which means a solid day. I charge it overnight, unplug it when I go to work, plug it in when I go to bed, and I'm usually at around 40% by that time with moderate use. I don't generally have problems with battery drain.
The exception to this is when using GPS with the screen on. It's really difficult to use this phone as a direct PND replacement even though it's basically made for it (especially with Froyo, which fixes the GPS lock issues), because the screen and GPS together will drain the battery from 100% to 0% in about 40 minutes. My dedicated PND, by contrast, will give me 8 *hours* of continuous use on battery power.
Also, I have a 1000mah car charger and even with that connected, the battery still drains when using GPS and the screen (it just drains slower). I have to just turn the screen off when I know I won't be needing to make a turn for a while.
The one thing I wish about the Epic is that it had a regular old LCD screen. The AMOLED screen is the one battery killer - you really need to watch how long you have it on. In normal use it isn't much of an issue, but you just can't do much of all the cool things they advertise that you can do with this phone (like GPS or watching movies).
I do also keep my screen turned way down, which makes a difference, but it's still a killer.
Well, I reported over in another thread that with Froyo, and basically having my phone sit around and do nothing with no WiFi, GPS, Bluetooth, no "fixes" such as switching to airplane mode or killing the DRM service, and no "battery saver" programs, I was able to get 108 hours on a single charge with the stock battery (1500mAH). That was with the screen on time of about 50 minutes and talk time of about 40 minutes... (pictures here)
It all boils down to how you use your phone, but in a stock configuration, the power management seems to be better on 2.2 than 2.1 as shown by the large amount of "idle" time I was able to get on a single charge.

I don't disbelieve that - in my post above, when I'm talking about draining the battery with GPS and the screen on in 40 minutes, or when I'm talking about having 40% battery left at the end of a regular day, it's almost always with a screen on time of 30-40 minutes. So 50 minutes sounds about right to drain the battery completely, with nothing else on.
I'll bet if you had 0 minutes screen on time - just let the phone sit idle - you could have probably gotten 200 hours or more.

No I know, I was more just clarifying so it didn't seem like we contradicted each other. I think the important stat is really screen time and then any extra radios you have turned on. Just with the regular radio and nothing else, you could get ridiculous battery life on the Epic. It's the extra radios and screen that kill it.
My phone gets me through the day. About 20% down in 7 hours on standby, so thats decent. Heavy usage with full brightness on and live wallpaper starting in the morning, stopping at like 6 A.M...it'd probably die there, for me at least.
The battery is good; I'm running the dk28 rom but it really hasn't affected my battery life at all.
On phoenix kernel i was getting 20-36 hours moderate to light usage. With acs xtreme kernel I'm getting 12-20 hrs w/ moderate use.
That's about 3-4 hrs of screen on time, 45-60 min of talk time. Emails, text ing, twitter, xda, and some various forum reading. Angry birds if waiting in line somewhere..
Note: I leave background data turned off and manually sync/refresh mail/contacts/data. I have no need/desire to be alerted evrytime someone updates twit/fb. I also use juice defender.
Sent from my SPH-D700 using XDA App
I can barely look at my phone on full brightness - it hurts my eyes with beams of awesome.
I get between 13 and 16 hours depending on how much Angry Bird time I put in that day. If I'm doing normal browsing, facebooking, etc then I'll be closer to 16, but gaming drops my battery like a rock.
Thanks for the replies! I think I'm convinced a lot of it has to do with how you use the device. Pretty much how it went with the EVO when it first came out... lots of people complaining about battery and then it kind of faded once everyone settled down. All I need is to get from early morning to right before bed.
GPS with google nav is a killer on any Android with decent screen size and resolution I think. Anyway, I thought SAMOLED is supposed to save a little battery? Or is that only if the background is black? In any case, I usually dim my screen to 30%, keep GPS off, keep auto-updates down to a manageable size, and use some other tricks to save battery, so I should be good to go.
I tried to thank all of you with the new thanks button, but didn't realize there's a limit per day haha. I'll finish it up tomorrow.
As far as I am concerned the battery life on DK28 is amazing. I use overclock widget set at 1000/200 screen on and 400/200 screen off. I can pull more than 30 hours with multiple phone calls, texting, email, web and games for over an hour. Here's the screen shot I took today before putting the phone on the charger.
I've noticed a substantial improvement in battery life since upgrading to 2.2. However, I also began using the Epic Experience ROM shortly afterwards, which boosted it even further. That, plus Juice Defender nets me a perfectly acceptable battery life.
I used my phone heavily today and still got about 18 hours out of it before plugging it in before bed at a 35% charge. On top of that, my phone's never felt snappier.
whoa, is it normal for the epic to take 3.5 hours to charge? If so, any explanation? Past devices i've had tend to take an hour less... Running 2.1, does Froyo help?
Currently on Epic Experience with SuperPower installed. I unplugged the phone about 16 hours ago and it's sitting at 36% with light voice and moderate SMS/data use.
Battery life definitely improved after upgrading from 2.1, even with light use it would be dead in under 12 hours on stock 2.1/DI17.
How to get unbelievable battery life
I have some very VERY helpful hints of great battery life for the Epic 4g. (as i am on hour 26 to 28 and have 20% left with about 1 to 1.5 hours of screen on use.)
First off, use black, or almost black background. Our screens are superAMOLED. This means that if the screen is showing black... those particular black pixels... are simply not on. If you have the home screen black, and have no icons on it, then the status bar is all that is using power... maybe 6 or 8 percent.
Next, Lose the brightness. A few helpful hints on this. 1) uncheck the autobrightness in the display settings 2) turn the brightness down in the display settings 3) If you slide your finger from right to left across the status bar at the top, the screen will dim, if you slide your finger from left to right, it will brighten(this causes accidental brightness 4) cover this light sensor on the right side at the top (I believe) because the phone seems to have a problem always autobrighting even with the uncheck in the settings. This is done best with electrical tape, or perhaps finger nail polish. These things should ensure to always be at minimum brightness
Next, Install Frankenstein Froyo Rom(lightest rom=less cpu usage/blackest rom=less screen battery usage), And Genocide Kernel(undervolted)
Next, install task killer(keeps the rom at optimum efficiency meaning less cpu usage assuming you are killing the apps 3 or 4 times a day) install set cpu(This allows you to limit the cpu clock speed(400mhz is optimal usable and battery settings)
Things to remember, ALWAYS TURN THE SCREEN OFF.
If you pick it up every thirty seconds to see if you have a text, then just sit it down... whats happening now.. The screen is staying on for another 15 seconds probably. DUH!!! bye bye battery!!
TURN OFF THE SCREEN BEFORE YOU SIT THE PHONE DOWN!!!
Turn off gps when not in use.
Turn off wifi when not in use.
Turn off 4g when not in use
Dont use it as an mp3 player.
Dont talk on speaker phone.
Those last few were pretty obvious.. but some people need to be told.
I Hope this helps anyone looking to conserve battery. Follow these steps and i promise 24 hours plus ever time and often as much as 48 hours.
Enjoy
EDIT****
By the way, When you set yourself up with this rom, you are making your phone TWICE as fast... LITERALLY. Hard to believe that a ROM could be twice as fast.
With stock android2.1 this phone gets 800 to 900 in quadrant(benchmark tool/tell how fast your phone REALLY is) Stock android 2.2 quadrant score is a little better scoring as high as 1000.
With this setup, i have gotten as high as 1950 in quadrant. No joke. This is reflected as you cant even tell the phone is clocked down to 400mhz without heavy apps and REALLY paying attention.
I used to get about 8 hrs of use before having to charge. Battery would drain even when I wasn't using the phone. Since flashing to DI18 a few months ago battery life has been great. A good 15-17 hours of moderate/high use and minimal drain with the phone on standby.
I lower the brightness all the way, end the DRM process and do the TWS trick after a reboot. No fancy battery management app that disables all your phone for the sake of battery.
I expect 2 hrs of the screen being on before my battery gets down to 20-30%. Which I think is very reasonable for moderate to high usage.
At the moment it seems like I'm getting around 5 minutes per percent (around 8 hours of constant use). The weird thing is that seems to be the case across all use, I get the same results from web browsing as I do reading comics in airplane mode.

I get pretty incredible standby though with set cpu. I'll go to work and come back after eight hours or more with one or two percent gone.
Yeah the standby life is amazing
Sent from my Samsung Fascinate via Tapatalk
set cpu app helped me get amazing stand by times. i mean i lose 1% every 24 hours propably.
during normal use, i get average 4-6 hours. surfing youtube, downloading, playing games. usually 5 is about right. People who say they get 8-10 hours heavy use are on one.
I would agree with 4-6 hours with constant use such as reading or twitter browsing. I previously had a Nook Color with CM7 on it and got about the same. Standby is amazing I almost never turn it off.
After about an hour of surfing or playing a game I lose about 20% so about 5 hours. But when watching videos I get around 7 or 8 hours

This sounds awesome I just got 48 hrs on included 4--5 hrs of use. Down to 2% ... wifi is set to go off with screen (after 1 min) not. Sure wat else to change
Hmmm. I was hoping that rooting/SetCPU/screen settings could get me closer to 8 hours of life, but that's not the case. I'll probably just sell the Iconia since the battery life is my main reason for owning a tablet, and in this case it isn't that much better than my laptop.
Run time.
52 hrs. %79 & moderate use. Never shut it off & still testing. Want to see how long it can go until I reach %30.
not trying to be an ass, but what are you guys using your tabs for? i run taboonay rom with thor kernel and good to very good battery life. I use my tablet all day long at work for e-mails, pdf viewing, gaming when i shouldn't be, and playing around on the internet. I wake up at 5 am everyday unplug my tab and start the day. With said usage i can go from 6ish AM till almost midnight and still have 20-30 something percent battery left. I wouldn't say i use it hard core, but i put it work. Just charge it while your asleep and it should last all day. Now on the occasion i watch movies on it it does drain the battery like a bastard but i can still get 5-7 hours of non stop movie watching on it. I really can't complain about the iconias battery at all. If you expect this thing to run like Carl Louis all day long without plugging it in you're in lala land. Theres alot of threads on how to get rid of cell usage drain, and look at whats killing your battery it may be an app or something you did settings wise to drain it faster.

Completely agree, I got mine on Saturday and apart from the initial charge it's only been plugged in twice. Used on and off throughout the day on Sunday, most of Monday evening, all Tuesday evening and all Wednesday evening, playing games and on the web with a bit of youtube and playing around. First time charged at 35% on Monday evening, second time yesterday at about 11pm as it was down to 10%. I think that's pretty damn good myself. It's on OTA 3.1 and Rooted
As for comparing to netbooks, have a look at the size of the battery in a Netbook compared to the Iconia. Of course they're going to last similar amounts of time - The Iconia has a smaller battery but has less to power versus the netbooks larger battery with more devices to power.
I'm at 67% after about 27 hours with about 2 hours of actual use. I guess that's ok. I flashed the Minimalist rom on Tuesday so I probably haven't given the battery enough time to break in. Sorry for being a *****, I'm just impatient >.<
I was kind of afraid if it would last me through a day of classes when college starts back, but I think I'll be ok.
I was getting around 5 days total with 1 to 2 hours display usage before the update to 3.1. Now it only goes 2 days when on standby with less than an hour of usage. Going to download SetCPU and try that. I have not changed anything (widgets) since before the update, so I have no idea what's eating up the battery.
Does anyone use there tablet in this post?Lol
I use my tab all-day long and I usually have 20% by the end of the day.

I use my tablet about 4 hours a day
I have to charge every 2 days
I charge during 2H30 arround.
Mine has been doing pretty well lately. I guess flashing roms took its toll

setcpu settings?
I'm using SetCPU as well, but getting no where near what you say. I left it on sleep last night and it drained 15% - same as before.
But, maybe I'm not using it right. I enabled the "screen off" profile and dropped the speed.
What are you doing/setting to get that standby time?

set cpu app helped me get amazing stand by times. i mean i lose 1% every 24 hours propably.
during normal use, i get average 4-6 hours. surfing youtube, downloading, playing games. usually 5 is about right. People who say they get 8-10 hours heavy use are on one.

Ok, I activated a couple more profiles including "time", temp, low battery. Low battery definitely turned on and I saw the change in the icon on the bottom right. I think the "screen off" is not turning on - basically can't see it when the screen is really off . But, it's definitely draining the same amount of battery.
Am I doing something wrong?

SetCPU didn't help mine either. Tried a few different profiles. I thought the one that would help the most is Screen Off, I set it max and min to 216mhz. No difference in battery drain overnight.
How often do you charge your rooted nook simple touch? after i rooted mine after reading on it for about 6 hours for 2 days, my battery dropped to about 78%. Is this normal or my battery draining too fast? also when nook goes to sleep mode it doesnt drain battery right?
It kinda depends on if I'm using it a lot during school. If I have the WiFi enabled and I'm taking notes with a lot of screen refreshes, then it ends up at about 50-70% battery at the end of the day, at which point I either charge it that night or the next. Other times when I don't use it for much other than writing down homework, it doesn't go down too much. I haven't charged mine for a few days and it's at 40% right now.
I don't charge mine all that often depends on just what I'm doing with it. If it's got wifi on it's a couple of days, if I'm just reading or not using it it's a lot longer. I intend to eventually do a battery test of not using it, using it without wifi, and using with wifi, but it could be months before it gets finished (or started) since I don't have multiple nooks. lol
I've only done testing for 10 hour stints, but here's what I've noticed:
With wifi off and the unit mostly sleeping, it uses about 0.14% battery per hour.
With wifi on and the unit mostly sleeping, it uses about 0.9% battery per hour.
With the wifi on and using the unit furiously, it uses about 8% battery per hour.
I haven't had the unit long enough to develop any "typical" daily patterns yet. I did set up Tasker to only turn on wifi when select apps are run, and shut it back off when they close. This seems to give me the best of both worlds.
So to answer the question, I charge it when it gets low (< 30%). How long that takes varies based on usage.
It seems you all are lucky. I am using my nook the same way as bobstro, and I have had my nook for 3 days. I charged it completely. After reading for 4 hours max, and playing with android for 1 hour, I am at 30 - 40%. What is going on?

Make sure your wifi isn't needlessly running say when you're reading.

A lot depends on how many screen refreshes you're doing, and network/wifi usage. If you're rebooting a lot, and raiding the Market, it will go more quickly.
Try just letting it sit unmolested for a bit and see if it levels out. With wifi off, mine is barely sipping power when in standby.
You also could be seeing bogus calibration. It's not dead until it's dead, regardless of what the gauge says. I've had Android devices blasting audio for 3 hours when the gauge read 1%. I'd give it a few more days and charge cycles before worrying too much. I think many of us panic when our battery doesn't last long the first few days, forgetting that we're playing with it constantly.
Of course, if you're still seeing poor battery life after a few days, definitely take it in for an exchange!
Ok. I charged it to 100% last night and then turned it off when it completed. This morning, I turned it on, and it has been on for a total of 4 hours. 2 of these hours were in standby, a half was reading, and the rest were taking notes and chatting with friends. Two hours were spent with the wifi on and two were spent with the wifi off. It is at 90% now. I think the part about misreading the level is what happened to me.
On a related note, anyone know of a good battery monitor widget for ADW?

When I'm in compulsive battery tracking mode, I use Battery Monitor Widget Pro ($) for the graphing features. It allows me to go back and compare a week's worth of battery performance data. I also get a good feeling when I glance at it and battery availability has been flat for an extended period.
There's a free version, but I don't recall how useful it was.
Once I'm comfortable with things, I plan on removing it and any other monitoring tools, as they do consume some battery themselves.
Thanks. Will have to check that out.
