[Q] Why is my battery life so awful?

I was at 100% battery at around 2:40pm today. I left and went to my brother's for Christmas lunch. Now, at 4pm, it's at 67%. All I did was Facebook (via the browser) and listen to some music (not the entire time). I frequently killed all the running apps, too.
I'm running Axura RC 2.5. I flashed it via Clockwork Recovery.

Then how do you manage backgrounded apps that you aren't using? They just drain the battery, no?

No, they don't. It's all related to how the Android OS manages applications. There's a ton of info about it - just google it. If you have battery draining issues, most of the time it's because you left something running that's constantly downloading/connecting to 3G or is doing something CPU intensive. Take the new Facebook app for example - if you use the chat function and you don't log out, it keeps you logged in and that will suck your battery dry. If 3G is spotty, you'll also have battery drain as the phone switches back and forth from edge to 3G, trying to connect.
I used a task killer when I first got my phone, because some moron at the AT&T store recommended it. My battery life got much better when I unloaded that crappy app.

I don't use FB chat, nor have I had unstable connections. I've had constant HDSPA all day. Could it be an issue with the ROM? I have WiFi, Bluetooth, & GPS turned off, as well as Brightness as low as it can go.

Hold down the home button and open task manager...
Also i noticed that using 3g on low signal kills the battery, try to use wifi...
You can also try assonance, i think its clocked 200 mhz less than axura, so you might perceive more battery, and it is as stable
Or try recalibrating the battery
Pd maybe it is an issue with the modem draining too much battery, you could try a different one, i bet if you dissable 3g your bat will improve a lot

Custom ROMs give you more speed, more power, more more more. That comes at a cost. You will have crappy battery life with some ROMs, and other ROMs may have better battery life.

For normal day to day work, EDGE should be fine. Switch from EDGE to 3G when u feel need more data transfer speed. This should help.

I wanted to try Assonance, but whenever I tried flashing it via Clockword recovery, it froze at 'installing update..'. About to try Darkys 7.0.1.

Could it be a deffective battery? I used to get 7 hrs heavy use (web, games, music) with my original battery. I bought a backup battery (same thing, Samsung OEM 1500mh) and I am impressed I am now getting 12-18 hrs with heavy to moderate use. I guess I had a bad battery to beging with.

elektrisk,
has your battery life changed since you first flashed axura? if so, it is most likely due to an app you installed after flashing the rom. if your battery life has always been "awful" then you should consider flashing a different kernel, or another rom & kernel altogether

Reasons to Wait on CM7

Just wanted to gather together the current remaining problems with CM7. What apps don't work, what's unstable, etc...

It actually seems very stable for me. I like it more than nookie froyo. With the 1.1ghz kernel it runs very smooth with launcher pro.
Every app I've tried works fine, and best of all - they show up in the market.
Its definitely worth a try, you can always go.back to what you had if you don't like it - just make a backup.

Bawb3, are you using dalingrin's overclocked kernel? If so, are you able to mount your nook on your computer via USB? I just installed the kernel last night and I'm unable to get USB debugging to come up when I plug in. I tried on Windows 7 and OSX and nothing happened in either OS.
Other than that, I love CM7. I started out on Customized Nookie Froyo, but I was having major issues with scrolling speeds and weird market issues. So far CM7 has been rock solid and blazing fast. I would recommend you give it a go.
Just make sure you use one of the latest nightlies if you do. The customized versions are nice, but no one does CM7 like the actual team.

New NC user this week, I've been running CM7 on eMMC for about 48 hours (first nightly v12, now v13) and it's been very stable. DSP video is the major thing lacking. Flash is smooth (including Hulu). I am having some trouble with seeing my installed/purchased apps in the Market but there are work-arounds I haven't tried yet.
I noticed in v12, Google Reader worked 100% fine and Maps FC'd. Now in v13, Reader scales down to 480x320 as soon as I open an article, but maps works fine. I've read this is a problem with DPI settings but I haven't got around to fixing it.
Overall if you're sick of B&N's Android, CM7 on CWM 3.0.1.0 seems to be the most stable of all the ROM's I tried, even in its nightly stage. But I have read of other peeps having major problems. I just really love Gingerbread. Google has really got a winner with 2.3

battery life is horrible w/ CM7, lots of drain when sleeping.

I'm not too concerned with the battery drain considering the tear downs have shown that the battery is plugged in and not soldered onto the board. By the time we kill these batteries with multiple charges someone will have put out a kit to replace the battery yourself...just like with the ipods that weren't supposed to have user replaceable batteries.

I second this, i notice it drains the battery pretty fast when im not using it. not really sure what it is doing. its not like its connected to the internet or doing something productive for the battery drain.

I turn off WiFi when I'm not using it (you could use Tasker to have it automagically go off/on at sleep/wake) and battery life improved significantly. I'm guessing when wifi is on, a lot of background activity happens.
But battery also isn't a big deal for me either. I probably use the thing for about an hour a day untethered, and the rest of the time it is plugged in.

It might be that an app like TweetDeck is scheduled to get updates every 3 minutes or something. I make sure to turn all of that stuff to manual as I pick up the Nook with checking it in mind anyway and can wait the few seconds it takes after I hit refresh.

Yes, battery life was was a lot better in Froyo for me. However I had a load of other problems in Froyo such as market intermittently not working, wifi problems, flash not working in firefox. I am sure it could be fixed, but it worked out of the box in CM7 and I liked CM7 UI much better.

Is anyone running CM7 out of an sd card?

If you're seeing battery drain, it seems SetCPU profiles eat up a lot of CPU. Just use the inbuilt settings (Settings > Cyanogenmod Settings > Performance > CPU)
Dalingin posted a new kernel that supports USB mounting on N13+ and also a new Interactive governor which should be faster.
DSP is really the only thing missing. I replaced Google Reader with a dolphin bookmark to the smartphone site, which I feel works a bit better anyway.

I just watched the video below and am pretty close to loading this. I tried Nookie Froyo was wasn't happy at all. I actually like the rooted stock appearance and performance except for the lack of flash. I just wish these ROM's allowed me to make the home screen look like the stock experience with the "continue reading" options on top and the stock B&N reading/store app.
http://www.youtube.com/watch?v=u1Z29zs70YE

I'm running CM7 v13 and I feel like this is the best one overall. I had a few minor hiccups with the wifi but i found a work around to it.
Contrary to what people say, I am impressed with the battery life. This is why. The original NC is used as an e-reader, but i purchased it as a tablet. I haven't had alot of experience with it, but i was able to get at least 6 hard hours out of it with the OC. Left it on overnight (roughtly 6 hours) with wifi and battery only dropped like 5% which is pretty good to me.
The only gripe i have is the DSP but that's tolerable considering all the other advantages of it.
The xda community has been very helpful and alot of the quirks with it has already been worked out if you do some searching in the threads.
Just my 2 cents.

Quick question on the nightlies: If I update from lets say #13 to #14, does it erase everything I had installed? or is it just and update that keeps all the apps and settings?
I am on #13, and some problems I noticed:
- Wifi would go on and off by itself coming out of sleep
- The "clear" notification button is REALLY unresponsive (might be a hardware issue thou)
- Takes FOREVER to charge (more than 5 hours)

As long as you don't wipe your data (though do wipe your cache) before reflashing, it should keep everything. It kept everything for me from v12 to v13, and then kept everything from v13 to v14. You should always double check the important stuff though.
I have the same responsiveness problem with the Clear button, but I'm 99% certain that's the hardware. I have had response/accuracy problems consistently in the corners of my screen, especially the top. Since the problem was on stock, nookie froyo, and CM7 (it's actually a lot better on CM7 than stock), I'm guessing it's the touch panel's fault.
Charging goes a lot faster for me if I've got it plugged into a wall (like 2 hours for 30% to 100%) instead of my computer. Probably a lower current coming through the USB on my computer than from the wall plug, I get the same difference when charging my Milestone. Don't know why the ROM would affect charging at all.

The only main problem with CM7 is that video acceleration doesn't work. That means no Youtube app, Orb app, playing x264 files with the local player, etc.
That is a deal breaker for me, but if its not for you then.....

Battery sucking down fast

I've got my autonootered 1.1.0 NC and it is working great. The only thing is the battery seems to be running out really fast on this. On my wife's autonootered 1.0.1, the battery isn't running out nearly so slow and we have all the same apps, although some of mine, since it's newer, may be more recent versions.
One thing I noticed is that she has very little time on "Android system", whereas 2/3 of the drain on mine is from that. The only apps that typically run though are advanced task killer and batter indicator. I regularly shut down everything else.
I've also renamed phone.apk and the telephony(something).apk on both of them as well.
Is there anything that will deep dive into "android system" on battery use? There are no rogue apps running (at least according the task killer). Or any suggestions?

First thing I'd suspect are live wallpapers followed by widgets. Verify that you have a plain wallpaper and remove any widgets that you would anticipate are doing frequent polling of any kind. I'd remove that battery indicator one and see if that helps.

Running zeam with plain nook wallpaper (just like on my wife's nook). No widgets. Am seriously wondering about the battery use thing though.

Like I suggested, uninstall that battery indicator app. You didnt mention which one it is so for now based on the only info youve provided thats the only advice I can give.
In one test I did on my nookie froyo install I'm running, I tried a new spruced up kernel and ran a battery status widget. The widget caused the nook to stay out of deep sleep and also out of lower clock speeds when idle resulting in horrible battery life.
Are you running setcpu on either or both nooks and if so are they set the same?
Sent from my nook color using Tapatalk

Try systempanel lite task manager by nextapp in market. It might help show ram and cpu usage of things.
Sent from my nook color using Tapatalk

When not using wifi turn it off. That will save you some battery life as well.

Keep the suggestions coming
The battery app is "battery indicator". It is usually running on both nooks, but mine has a more recent version I think (this is my main suspect right now).
We always kill the wifi when not using it, so I know that's not it. Also not running setcpu on either.
I sucked down probably 5-10% while just reading with only "advanced task killer", "battery indicator", and the stock reader running for less than an hour last night.
I'm going to try systempanellite and see if that tells me anything. Also going to charge it up to 100%, boot into CMR and reset the battery stats.
If it is the battery app, wondering how to find the older version to downgrade to, or maybe just find a different one, I suppose...

45 minutes of simply reading and went from 99% all the way down to 88%. No battery utility. Systempanellite (only running for a few of those minutes) didn't really show anything sucking either.
Only other difference I can think of now is that I disabled OTA updates on my wife's nook.
I wonder if I just got a bad nook, battery wise...

So ~10% from about ~1 hour of use? Might be a little high for just reading, especially if your brightness is low and your wifi is off. However, I note a 10% per hour discharge with average use. I get about ~2% or so overnight loss with screen off and wifi off.
Rooted 1.1, Monster root pack. Overclocked with Dalingrin's kernel.

Looking at the two nooks, side by side, I notice that on mine, AFfileDownloadService and CloudService are background, while on my wife's, they are 'Service'. When DeviceManagerService is running, that is also background on mine and service on hers.
Could that be why the "Android system" is sucking so much battery? SystemPanel doesn't show anything sucking cpu....
I know it's supposed to be around 10 hours, but that works out to be about 7 hours reading a small, simple epub, which has me concerned.
I did lower the brightness on mine to match my wife's exactly. It was less than halfway, but heres was lower, right in between the two esses at the end of 'brightness'.

A more deliberate test shows 1% drain every 5 minutes (almost exactly) while just reading. That's a little over 8 hours and still less than I expect. Maybe I need to tweak the brightness a little more...

[Q] Traveling with my Nook question?

Ok guys\gals, I have a question that I haven’t seem to find. Right now I’m using CM7 stable on my Nook emmc drive and it works great (Special thanks to all Devs in the Android world that make all is possible). Me and the family are going on vacation at the end of next month and I’m little concerned about battery life on a 5 hour plane ride with my Nook. I know of the sleep bug that CM has and everyone has been working on it but right now I get about day use out of it with normal to heavy use. This is fine because I’m always somewhere I can plug into if the power starts to get low, but now have a little concern since won’t have power. I have successfully converted a few movies using Handbrake and would love to use my nook as entertainment\movies for me and the family while in the Air. So in my testing I haven’t been able to get through a few 2 hours or so movies without the power draining down fast.
Ok with all that being said, it’s my understanding is that the stock ROM with root (Nooter 3.0) works great with Video and has good battery life. Would it be idea for me to just restore to a stock rooted Rom, then create a CM7 SD-Card? The cm7 card would be for my use only till we great back from Seattle. Mainly I’m just trying to keep the kiddos happy since they have never been on a plane before LOL. They LOVE all what my little Nook can do and love watching movies on the bigger 7 in screen (Transformers is Awesome on the Nook by the way). Any suggestions would be great.
Thanks Guys\Gals…
Derek.

Yes, what you propose will work.
I actually have a dualboot on my NC with CM7 as a primary boot; and the stock (rooted) on the secondary partition. (you can follow the dualboot thread in the developer section).
However, while you are actually USING the NC, the battery life shouldn't be terribly different between CM7 and stock. The biggest difference in battery life is while in "suspend" mode, because CM7 doesn't go into as deep of a sleep mode as when in suspend while in stock; so if you are willing to actually power down the NC, rather than suspend, you shouldn't experience any additional power drain while on CM7.
If you still have significantly more power drain on CM7, it is probably because you are overclocking. I have found that shutting wifi off when not being used, being conservative in the screen brightness, and adjust the the processor tweak in the cyanogen settings to "conservative" will help with battery.
All of that being said, I hope to get an external USB battery the next time I need to fly ....

My Nook, running CM7 Stable with screen brightness at 100% and wifi off, uses about 18% of its battery life for every one hour of full-screen video that I watch (.avi files, Rockplayer, mostly). The times that I've flown with it (only once since installing CM7) I usually watch an hour or two of video with internal battery then plug in one of those Duracell rechargeable batteries that you use with a USB cable to power portable devices. Using the rechargeable with a Nook-specific cable (in case that helps) my battery drain per hour of video drops to 10%. On night flights both rates improve somewhat due to much lower brightness levels. Plus, if the Nook is plugged in but inactive (powered on or off) it'll ADD charge 5-10% per hour. One charged 750MAH battery (half the size of a deck of cards) and I'm good for at least 8 hours of heavy use (could go longer, that's the most I've needed).

As jasoraso mentioned, you're really not going to get much better life while using it, if you switch to Stock. Cm7's battery usage is only when usage is suspended as it can't go as deep into sleep as the stock os can.
So even if you move back to stock, you're not going to get better life while watching videos. Your best option would be as both posters before me mentioned, an external charger.

Battery not so good

I didn't use the note much, but it needs to charge each day. This is bad than tablet. Any software to save battery? I tried 'air plane mode' sofeware, but it also turns off phone after sleep.

What apps and widgets are you running? Have you gone through 2 or 3 full discharge/recharge cycles? There are apps out there that can detect if any app is consuming your battery but you will have to search the forums as I don't know of any first hand.
Also, which ROM are you using? When I was using Rocket Rom v22 with AbyssKernel 4.1, my Note would last more than a day on the same charge even with moderate use. Give that a try as it also really boosts performance.
I'm currently on Team Rocket Rom (ICS based) v5 but have not used it extensively to comment on battery yet. So far with 3 activesync email accounts (all push), some widgets running (weather, clock, etc.) and the Note sitting idle consume about 2-3% battery per hour. Will monitor this.

most smartphones ned to be charged every day, what battery life are you expecting to get ?

battery depends on the usage and applications you installed on the phone.
have you tried rooting already? usually custom roms have the best alternatives of extending your phone's battery and giving it an optimal performance.
Try to stop some bloatwares that your phone's loading up everytime it starts up(from rebooting)

I am using la2 rom. Here i attached an picture.

Geez... i personally feel that one day charge is reasonable especially with the juice required to drive the big display.
Anyway, Juice Defender premium is one app that has helped me, and may help you too.
Since you got Activesync, with the premium version of JD, you can customize app to be excluded from 'power saving', so that the inbox is up to date.

+1 for juicedefender.
Other tips that may not be obvious to first-time smartphone owners are:
1. Set your screen brightness to auto. You don't need the brightness cranked right up all the time.
2. Disable bluetooth and GPS if you're not using them. Juicedefender will do a pretty good job of managing your other radios.
3. If you've got email syncing set up on your phone, set it to check as rarely as you can put up with. Push email uses a LOT of battery life, and even a scheduled check can blaze through your battery if it's happening often enough.
4. If you've put on a custom ROM your phone may be reporting inaccurate battery stats. Give it a full charge, boot into clockwork recovery and wipe your battery stats. You'll find a few days after that your phone will start reporting more accurately.
Good luck, and if any of this was unclear feel free to ask further questions.

Try a later ROM to see if the same issue exists. I think you should instal rocket rom v22 - you'll be happy with performance and battery life based on your usage.

try to calibrate your battery as well... there are many apps out there that offers better battery calibration or you can do a manual calibration as well.

Give it some time and upgrade your ROM
I am getting great battery life. It runs for full day (24 hrs) with 30% of battery usage. though in a day i dont use it much, just 5 to 10 calls of around half an hour to 40 minutes.. data and gps always on.. screen brightness on auto...

My note running the OEM battery last me about 6 hrs.
Averages about 45mins talk time/day
About 50 SMS/day
Screen brightness set to 100

Refreshes the daily weather using Accuweather every hr
Bluetooth always turned on

^ This. Or better yet, just always set your brightness to the lowest brightness setting, 50% afaik. And use black/dark wallpapers and always turn on night mode (if applicable, especially when using your browser)
If in case you need to adjust the brightness, you don't have to go through the jungle of settings, just click notification bar and slide horizontally to change to your preferred brightness.

Jd is hit n miss will actually helping out. If your phone sleeps a lot jd is nice at keeping cell or wifi off if your like me and on it every 10 minutes then toggling data and other things can consume more juice. .... I have tried with and without on my tablets and phones and see no big difference depending on use.
Sent from my Ice Creamy Galaxy NOTE

I was pretty happy with my battery until two days ago. I use my note very little, for e-mail checking (which I pull manually) a few times a day, and to make two or three phone calls per day. I also text my kids occasionally. GPS and Bluetooth are off most of the time. Battery used to last me about two and a half days under these conditions, which seemed reasonable to me. All of a sudden, two days ago, I charged my battery, and after a full charge it drained 60% overnight. Thought that it was a fluke, so rebooted my phone, fully charged again, and the same thing (over half of the juice gone overnight) happened again. Battery stats tell me that Android OS were 100% responsible for overnight drainage. Any clues? I am on stock ROM, by the way.
Thank you.

Get a good app to check what is using the battery or keeping the phone awake. This last is the most likely.
Baddass Battery Monitor is my recommendation.

Not a single phone call, only used about 10 mins. after 21 hours only 11% left. Install Jd with 'balanced' option.

Thank you. I will give that a try.
Badass, got to love that name....

Ok, I used the Badass monitor to see what's going on. Once again, no phone usage, quick overnight battery drainage. Android OS 100% responsible, and the main power sucker is the Kernel (96%). Why is this happening? And, is there a remedy? I have changed nothing that would trigger this! My Note is still within the return window, so if there is anything wrong with it, I will return it.
Thanks again.

Badass Monitor is very useful, my note was drained by Dolphin Browser, it used 38% of battery. Seems like for this browser, if I only press home key to exit, It will keep running?
I think the reason the battery drain fast is we press 'home' key to return to main menu, that will keep a lot of apps run in the background.
