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.

If you have ever installed the current widget on your Thunderbolt, I just wondering how is the number when the phone is left standby. Please share here, I am looking forward to see the result. Just average result of current widget if you leave your phone to standby mode.
If you root your phone, please mention that you root it. In case it makes different between rooted and unrooted.
Beginning from me.
My average result is 36 mA without root.
Thanks before.
38mA rooted

How are you drawing more current from a rooted phone . 4g?
I'm down to 11mA idle power draw on ginger bread. They made enormous improvements on idle power on 2.3. It's excellent, I'll go hours without losing any battery of idle time. Finally.

Sorry yeah, my nexus one actually. Just wanted to help compare how improved ginger bread will be when you guys get it.
Just today I have been unplugged for 15 hours and still have 71% battery left, connected to WiFi all night. Granted this was idle use, but it was never this good before. I exported the logs and idle current stayed level at about 12mA the whole time. My idle power on froyo stayed around 30-40mA no matter what I tried. I'm happier than I've ever been with android right now!
Something for you guys to look forward to.
I wish the carriers would realize that most of us want the ability to use the lastest greatest rom as soon as it hits and would quit locking their stuff down. If nothing else, I would think that google is big enough as an OS to tell the carriers to stop using their OS or leave them vanilla. I mean for a company like moto, who are they going to use? WM7? please. Sometimes a tiny bit of force is needed.
I am at 60mA. What gives? My battery dies in the middle of the night every night. I am rooted.
26mA here, stock.
I must be doing something wrong, mine says 180mA.
It makes a difference if a) you're plugged in (in which case current is showing you how much charge you're getting, not current usage), and b) if you're using the phone (tip, turn off the screen, let it sit for a minute, then check).

Right. The best way to check that I have found is using the history button. Put it to sleep then wait a half hour then check the history. I set mine to update every 5 minutes.
I use Battery Monitor Widget:

I noticed that most of GingerBread build consume less battery. Right now, I am still looking which activity drain my battery.
First off I want to thank Nitro for Eclipse it is by far the best my phone has run since purchased.
I have noticed tho on .5 that my battery seems to get used up a lot faster. Has anyone else noticed this? I know that Nitro said in his ROM OP that you could change the cpu frequencies in the init.d script. Has this worked for anyone?
If so could you please let me/us know what you did to get better battery usage.
My battery too died really fast when using v5. I adjusted the cpu freq to 216mhz and calibrated the battery. Also tried Overmind's init hack w/ no luck. I have the extended battery and it would need charged after 6 hrs or so. I use my phone a lot but I used to get 11+ hours under similar use..
I recently went back .2.2 where I had better luck w/ battery life. Gonna test this version and hope my battery isn't on its way out.
EDIT: After going back to .2.2 I'm now sitting at 30% with 16+ hrs of similar heavy usage. Nothing against Nitro's v5 but I've had MUCH better battery life on .2.2 Never gave much thought to the reboot "fix".

How do you change frequencies? I was trying to change governors but it wouldn't let me
Sent from my DROID X2 using XDA App
The only way I was able to change governers is using the Droid overclock app and installing busybox OR flashing a init.d hack. Not really sure how the app opened up the governors for me, but I know for a fact that init d hack works.

So there is no real fix as of yet. I am not going to reboot my phone after each charge, that is obviously a band aid fix and I actually like to see how long my phone runs (well) without needing a reboot.
I really like 0.5 so I'd rather not go back to 0.2.2 just for the better battery usage.
It cannot be a kernel issue because since GB was released the Kernel never changed and it hasn't been since I flashed Eclipse 0.5 that my battery life has decreased.
It must be something to do with the ROM, I am sure it will be straightened out soon. One of the genius script writers will provide a hack or there will be settings tweak that helps. Until then it is not nearly a deal breaker, I can still use my phone like normal. It is just something I happened to notice now that we have 1% battery level increments. 5% in my case, I'm running TheMuffStuff's Cyan Ice Cream Blur.
I'm Pretty Sure The Kernel Did Change, Kinda The Big Topic With 2nd-init.

Sorry I don't mean to be rude or ignore the fact that rebooting fixes the battery usage just feel it is more of a band aid than a fix.
Mikey, I apologize I didn't realize that the kernel was able to be modified with a locked boot loader. I do realize that 2nd init hijacks certain process within the kernel and allows for modifications I just didn't know that the actual kernel we were running in eclipse .5 differed from the stock GB kernel.
I will be the first to admit that I have a lot to learn when it comes to the Android OS. I am very thankful to those with the knowledge to bring out these phones full potential.
Just Wanna Be Clear I Was Referring That Gingerbread Kernel Is Different From Froyo.
Not Stock Gingerbread To Eclipse Rom.
I Could Be Wrong And That's Fine, Wanted To Be Clear If I'm Wrong.
I never noticed the battery problem 'cause I'm used to rebooting my phone every morning anyway (coming from a long time windows mobile user) that stupid piece of crap got me in that habit, but this phone is fast as all get out. you can hit reboot, go take your morning whiz and it'll be back up and running before you even start peein!
it's like the playstation 3 of smartphones, just be patient and wait for the software to catch up with the hardware.
maybe adjust your usage a little too. turn off all your stupid data-hungry apps. the 3g radio in this thing sucks juice like nobody's business. but you can play games/music/movies all day long in airplane mode.
I've already gotten 7 solid hours of playin music + stupid zombies while traveling. I'll turn my radio on only when I want to be bothered.
it surprises me that even the wifi doesn't kill it like the 3g radio does. if I'm on wifi all day long my battery life is AWESOME. I've even taken out the 3g tweaks from my eclipse.5 and now I have no trouble getting 12+ hours between charges. the absolute worst thing for the battery is music + wifi tether (I like using the phone hooked to my speakers for general music listening 'cause I don't miss any notifications)
the fact of the matter is, these phones will never have good battery life until the radio gets a serious update/overhaul. it seems like it transmits at FULL power constantly even if it's not necessary.
you want battery savings? turn off background data and put it in max batt saver mode. it doesn't make things that much slower and as soon as you wake the phone it reconnects pretty quickly and updates whatever you were missing out on. that and honestly, it's nice to not be notified about every piece of junkmail that reaches my inbox on a daily basis. people can text you just as easily as e-mail, and if they can't respect that, they don't deserve your respect in return.
who even had a cellphone 15 years ago, let alone all this other crap that comes along with "smart" phones. we all got along fine without them before.
come to think of it, I have never had issues with music skipping either, but I don't let my phone frivolously piss away data either. something to think about, but I remember the days when I paid by the MEGABYTE for data service too.

Dunno how others feel but I liked this post.
I recommend juice defender I love to set it to turn off all data while the screen is off. And I set it to turn it on every two hours for a minute to retrieve gmail and such. Has helped save so much battery lately and works great. That way I don't have to mess around with going g into settings to turn off data and on every time I wanna check. I also leave it in my notification bar so I can just pull down and tap and it cuts my data. Also have seen I can set it to turn off and on data when using any app I just haven't configured that setting yet. I have noticed up to 4hrs more battery when I have juice defender enabled .
I agree completely on the radio. Even when I have a very very good signal if im not using wifi and pulling data from 3g my battery has been almost completely drained within a few hours of heavy use just browsing the web. Its crazy how much juice it sucks down.

I will definitely check out juice defender. I am by no means complaining about the battery usage at all. My phone still lasts all day with the same amount of use I have always had.
I had just noticed a difference going from Eclipse .2 to .5, and it was even mentioned by Nitro that people may experience a higher battery usage with this rom. I was simply wondering if anyone had applied a script or modified a setting (as stated in OP) that made a difference. I tried to change the cpu values in the script but it didn't make a difference for me. If anyone did make a change please post the change you made and how you made it.
Sounds like rebooting after charging, or using software to modify data usage is what works the best for now.
I have a serious problem.
My battery is draining more charge when it is powered off than when it is on!
First off, yes, I am powering it off and not just putting it in sleep.
What happens is this; I power it off for the night, battery at 100, turn it on in morning, battery is at 70-50! Now get this, I reboot this morning, battery instantly drops another 10%!!!!
What on earth is going on here? Does anyone else's have similar problems? I did Google it, but can't find a solution, although it looks like I am not the only one with the problem!
Please help!
Edit: here is a screenshot of my battery use, if anyone wants (sorry, don't know how to post picture other than as attachment)
I had this situation once before. After I updated my firmware to 2.3.5 from 2.2, it never happened again. Hope this help.

Mine is US version, comes with 2.3.5.
Use the original version 2.2 Froyo that came with it. I did not want to update because everything works fine. no bugs of any kind. I think I did the right thing, because I have read several bugs related to the update to 2.3.5.
Do not always update is really necessary. Unless something does not work well or update the device will really improve. But this is not always true.
In my case the battery has excellent durability. An exception to games but that's with any Android. Even with a 2500 MAH as the G70. Luckily, I'm not adept at games.

I've notcied that my battery would drain faster when connected to wifi at home.
I have 5.0, 2.3.5 US version. I had a problem getting mine to charge to 100% (seemed to stop at 80%), but finally it hit 100%. Got to 80% in 3-4 hours, got to 100 in 6 hours extra!
Mine seems to drain "normally", at 65% after 23 hours. Not been doing a lot with it, just messing with apps (installing, rearranging). I always turn off wifi when not using it (especially if there's none around).
You might install "Power Tudor" and see what exactly is using that much power to drain yours that fast. Could be something stuck syncing (like if you have mail set to sync every 10 minutes).
Well, the thing is, it shouldn't be syncing or doing anything while powered off! Oh well, I have just gone to putting in airplane mode, then letting it sleep at night, doesn't burn any battery that way anyway!
Just curious, isn't "airplane mode" the same as just turning off wifi, since it has no cell radios?
I also question the time scale on the battery chart, never seems right to me. If your graph is 10 hours, and it was off at night, I would think it should register than 6-8 hours (or whatever your "night" was. Looks like it was only about an hour.

airplane mode turns off all antennas (wifi,GPS,FM radio). Yeah the battery chart doesn't make Denver to me either, but whatever.
Just keep it plugged in at night, I guess.

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.

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

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...
Good afternoon everyone,
I didn't see another post on this topic for this device so I wanted to see if anyone knew what might be up. A few months ago, I installed the beta of CM7 on my Droid X2. It's been working great since then and I've been extremely pleased with the improvement over the stock build.
Over the past couple days though, I've been noticing that my battery reading has been incredibly erratic. An example last night had it go from fully charged to 4% in under two hours. When I plug it in, it charges at a normal pace up through around 25%, and then jumps to fully charged.
I installed a clean install of CM7 this morning and noticed the same issue persists. At first I thought maybe installing my new software drained it more than I realized, but it jumped from around 24 to 100% again while plugged into the wall charger.
I have several screen shots of the battery activity screen that I took when I noticed it acting odd. The one from this morning is attached below. If anyone could help me figure out what might be up, it'd be greatly appreciated. I wanted to start casually looking for a new phone, but not like this
Edit: I also have this one from just before I charged and just after the battery spiked downward.
Maybe you just need a new battery.
P.S. You talk on the phone a lot. lol

Heh, that's one of the things that has been acting up recently. That 65% is only a 7 minute call.
Well if its a software issue, an SBF should clean it up. And if it doesnt, Id say its the physical battery. But I havent been on CM7 in a long time. I forget what issues it had. I dont think this was one of them though.

I'll give a new battery a try then. I just wanted to check in before shelling out some money for a non-fix. I installed the 2.3.4 SBF this morning before giving 7 a reinstall and the problem seemed to reappear almost immediately.
Thanks for your help.
Try rebooting into recovery then go to advanced>wipe battery stats. Then wait for your battery to completely die before recharging it
