My X10a used to give a day worth of battery life when I was on Android 1.6 after upgrading to 2.1.A.0.435 it almost got doubles 2 days. A week back I installed black theme using xRecovery and JIT (I didn't take backup before installing it ).
Now the battery is good for 10 -12 hours only. I checked the battery usage, it is show 60% cell stand by and 20% display, my usage doesn't change at all.
Can any tell me solution without doing the repair will greatly appreciated
Thanks
Try going into xRecovery menu and do " wipe battery stats ". Could be you've turned up the brightness, and your display is eating battery?
Maybe you already do this, but these next ones improve battery life in general. Not that it would explain your change... Use the app APNdroid to disable data when you aren't using it. It has a no/off toggle widget for the homescreen that works great. Set WIFI to "off when screen off" along with APNdroid, and use Advanced Task Killer app set to aggressive, medium security, and "auto kill when a screen off". Set all system apps and any apps that you always want running to "ignore" auto kill.
There is argument that task killers actually do more harm than good or kills battery, but that is if you didn't set it up right. At least on 2.1. New versions of Android don't need task killers. If you don't like task killers, skip that. It's better to have no task killers at all than to have one that's set up wrong. Never set task killer on a timer, like every 30 minutes.
When I did all these things I still have 30%+ the next day if I forget to charge it at night with HEAVY use. Before I didn't always make it through the day. Hope this helps.
Thanks for your answer.
I tried wiping battery and then what I found is my phone is using much more power standy mode. The application have not changed and I already use advance task killer in aggressive mode
can JIT increase power consumption in standy by mode?
Don't know if this will help, but try using a fresh download of JIT custom zip. Then going into xRecovery/advanced options and wipe Dalvik Cache and then reinstall JIT. Also, try disabling task killer if you are still having problems.
i've had my x10 for 9 months and last month i noticed a change in my battery life even when i haven't made any significant changes to my normal usage (and settings). my old x1's battery lasted about 11-12 months... and i'm a moderate to heavy user. so it could just be your battery beginning see it's way out.
agentJBM:
I tried reinstalling after wiping Dalvik Cache but this didn't work, I'm stilling seeing drop in battery a percent a minute then phone on otherwise cell standby using the battery.
I guess I need to start from repairing again and installing JIT. Only thing I can think is that JIT is for global ROM but I had Canadian Rogers ROM
if that didn't work then I'll follow azian_advanced advise and order a new battery
While you're at it, see if you have the same problem before you enable JIT after repair software. That will give you an idea if it's the battery.
Also, try the procedure in the thread titled "[Guide] X10 Battery Calibration" found in the general section. I'd provide a link, but I am on my kick ass X10a.
Repair made big difference, I installed all my apps but haven't configured by emails yet but drop of 5% in whole night versus 90% drop earlier. I haven't installed JIT yet and i thinking leaving it alone for now
its crazy how jit seems to effect each phone so differently

Hi, I own a Xperia mini pro. My first android phone .I have rooted my phone. The phone's ROM hasn't been changed. I'm using root apps like CPU Master, Auto Manager Memory, SD card speed increase etc. Default launcher is GO launcher.
I had read in many forums that rooting a phone and using softwares like CPU Master may increase the battery life. Currently my average battery life is around 12-14 hours. It was the same when I hadn't rooted my phone. I leave HSDPA data transfer always on. That might be one of the contributors in draining the battery faster. I used to use Juice defender earlier. Though it seemed to increase my phone's battery life (mainly because of my setting to switch data transfer off when screen is off 'but' allow data transfer for only some selected apps even when screen is off), it used to make my phone laggy. I've used other apps like green power, tasker and others.. While they switch off data when screen is off, none of them have option to enable data for selected apps even when screen is off(which i need because most of my friends use apps like whatsapp, facebook messenger or gtalk to message me). I've also removed some system apps, like fun and downloads, popcap etc. Could I use any alternatives for the apps mentioned above which consume lesser battery? Or is improving battery life on rooting only possible when ROM and kernels are changed
Plz suggest an alternative to juicedefender that allows me to do what i want. And it'l be really helpfull if someone who has achieved prolonging his/her mini pro's battery life gives me some tips on the same.
33 1/2 hours since I posted this question. And still no reply.. I'm disappointed
Hope this helps.
Hi,
Bro u have a rooted phone , but you don't have a custom ROM that means that you can not overclock or under clock your mobile, so using cup master or set cpu will not help you.
Solution can be u an flash a new ROM having an overclocked kernel or you can flash a overclocked kernel to your current stock ROM or if you don't want to do any of this simply uninstall cpu manager as it will be eating unnecessary juice from your battery and not helping in any way.
Auto memory manager does improves battery life but only a bit, it basically controls the apps killing rate i.e. it manages how much RAM should remain free at all times helps improves performance of you phone, so don't use an aggressive profile because it will kill apps (background or paused or closed) very frequently which in turn will lead to use of your battery, instead use a mild or less aggressive or default settings this will improve both performance of your phone and use lesser juice as compared to a aggressive setting.
Also keep in mind since u r using Gingerbread so killing apps using task killers after every few minutes will not help , so u can uninstall task killers, also if u need a task killer it is already present in go launcher u can use that.
Juice defender is ultimate app which helps improves battery a lot, but u need to have optimized settings according to your needs.
My advice is use smart profiles by Antutu to create profiles for different timings i.e when you need 3g or wirelss or not as when your are sleeping you don't need wifi or 3g on.
Also best option of saving battery is reducing screen brightness.
You can reduce brightness to 20 % which you are inside the building or working under lights as the screen is properly visible.
And outside in bright sun you can use 35-50% brightness.
Keeping phone at 100% brightness will screw the battery life.
You can use LUX or ambident light senor for automatic brightness setting according to the day light or unnatural light or dark.
hope this helps you.

I forgot to mention point about serious battery saving settings.
1) Use lesser widgets only widgets you really need, as they are battery hogger.
2) Try to reduce push interval for email notification, facebook, twitter, weather widget because using 1-5 min push interval will use a lot of juice, try increasing interval to 30 minutes or more or use manual push if you don't need the notification updates every single minute pooping in. This part eats most amount of battery so if u can change the settings this will improve you battery life a lot.
3) Also watch if any unnecessary services are not running in background, because a lot of apps uses services which eats significant battery , so if there is a application which is not needed at all but is running unnecessary service u can uninstall it if you want, but this is not mandatory.
4) Lastly you can use watchdog app , it log the cpu usage by apps and will let you know which app is eating up a lot of juice. So u can find the culprit and find alternative app for that.

Hi,
I'm using the following rom : http://forum.xda-developers.com/showthread.php?t=1263292 ( CyanogenMod 7.1-cooper-KANG-RC1 Android 2.3.7 ) with a XXKPE kernel, and I'm getting very bad battery life. About 30 minutes of active wireless activity, a few calls and idle time otherwise, and the battery is at 20% after being fully charged in the beginning.
I have seen some attempts to map roms and kernels in terms of battery usage, but haven't seen this one mentioned in the list. Are there any known issues with this rom? (Couldn't fine any while searching)? Is this expected life expectancy for the ace? The phone is new so I don't think its the battery itself.
Also, I want to be able to easily control certain features with one click (for example, turn off 3G, mobile data and sync quickly). Is it possible to do such a thing?
With CM, go to Settings > CyanogenMod Settings > Interface > Notification Power Widget > Widget Buttons
then tick the stuff you want to appear on notification, so u can one click configure it.
As for battery saving, I'd recommend Juice Defender Ultimate, I've been using my phone for 7Hours with Wifi on non-stop, and now is at 68% from 100%. Juice Defender Ultimate is really good, if your willing to take some time to configure it.
EDIT: As for ROM, im using ICS Final with SlaidFastMod. I moved from CM7.1 because of the battery life. With Juice Defender, it could barely last 1 day with minimum usage (mostly idle)
Or you could make power saving profiles. using Tasker.
Thanks guys!
- Tasker seems really complicated, so I'll try to avoid it for now (looks like a big config effort needs to be put in)
- I'm using Juice Defender (free) for now, if that doesn't change much I'll probably try ultimate.
- The power widget buttons are helpful, was looking for that, thanks!
- The rom change I'm a bit worried about. Is CM7.1 known for being a battery hog on ace? Are the ICS roms stable yet?
So after some research and Googling, I discovered that "Killling" your app is only worse or has no effect for your battery life. Even using apps that "save" battery only harm it even more. I've been told these were the fundamental things to save battery ever since I even got my hands on a smart phone.. Guess I've been asking the wrong people.
So, what are real ways to save battery? I'm a heavy phone user, often surfing the net or watching Netflix on the go. Dimming my screen is not enough, are there any other techniques to prevent my phone from dying? I've got an Android 4.
If you're rooted:
Underclock
Undervolt
Change cpu governor/io scheduler
Flash different ROMS and kernels
Change your modem
And a few more.
Not rooted:
Use screen filter? Lol.
Update your firmware

I am rooted, thank you for the info! I'll be looking into it~
Get bigger battery?
Turn thing off lol only kidding but turn off auto updates such as news etc
If you look at your battery stats, under settings, you'll see what uses the most battery. Usually I find that my screen uses around 70% of my battery, but if you have something else high on the list you might have a "rogue app" preventing your phone from going into sleep mode.
If your screen is the culprit you can only save 10% or so by throttling your CPU etc. The only way you can make real savings is by reducing screen brightness.
Easiest way to save battery is use gemini app manager to stop apps being able to autostart when you don't want them to as then you don't have the os having to kill off unused apps to make more free ram.
For example a lot of apps can autostart when your wifi goes on or off, when your 3G signal drops etcetera including things like facebook or google play. By changing auto start for such apps you don't have to run a task killer which also saves battery.

i use the aokp rom milestone 4 atm, and i also have come accross a fantastic battery app called "Badass Battery Monitor". its free and details very very specifically what apps are using the battery most.
I have managed to increase my battery by rooting out the apps i dont use that are using prescious power...
Also, turning off useless app permissions for apps theat really dont need them and work perfectly well without them will also save on power massively. for this i use "LBE Privacy Guard" works an absolute charm
I have widget where I can turn off Internet connection, set brightness, GPS etc. Internet stand-by mode uses damn much battery... And when you don't use Internet, you can put on 2G, it also saves battery.
This may not benefit you if you are a heavy user but I find the feature on my Droid 3 that turns off 3G after 15 minutes of inactivity saves battery and also saves data. Not sure if this is a standard Android feature or if it would even benefit you.
Here with LG P990 and I don't have option to turn off 3G aftre some minutes... but if/when you didn't need high speed you can choose only 2G network (for example when needed receive only notification): this save a lot your battery.
Moreover you can verify battery consumption to see if there are autostart apps from your vendor than have heavy power consumption (for me there was OnScreenPhone) and use gemini app manager as explained previously.
In the end you can find out custom ROM for your device usually optimized for smoothness and power consumption.
First apps I download when switching to a new Rom to get a little control on battery are
Adfree- Get rid of ads, they eat a bit of battery.
DroidWall- Control what apps are able to access Internet under separate "Mobile Data" and "Wifi" Conditions.
Screenfilter- Dim the screen below factory settings.
LED's hack- Turn off the Softbutton Backlights (home/menu/back/search), even though they don't seem like it may eat up your battery, it is an extra 'light' that's on, even though it may be minimal, it's still drawing power.
Also, It maybe just a Photon thing cuz of the Pentile display but I always use if not completely Black background image, a dark one because the 'lighter' or 'whiter/colorful' images take more battery, same reason I always look for 'Inverted' or black themed apps too.
Turn OFF any 'Haptic feedback' settings on your phone (Keyboard, Phone DialPad, Screen/UI Interactions, etc..)
For Calls (Ringtone) and Notification settings, don't have them set to 'Ring and Vibrate' or just 'Vibrate' because the Vibration Mechanism will eat alot if battery. Some may argue that the Notification 'Vibrate' setting and even the Haptic feedback (which does in fact use the phones Vibration mechanism) would not kill battery because it's a 'quick' or 'minimal' use (depending on use) and but if your keyboard had the Haptic feedback on, thinking of how many times your touch the keyboard for even on Text message, try will add up and help kill the battery.
Turn OFF any/all Homescreen/UI Animations
Turn OFF any Auto Sync setting and instead have APPS sync in a specified interval, (Of course Depending on how important the information that's being pulled like Email) , Could be set to like every 4 hours to sync an so on.
Manually input Date/Time settings instead of "Get network provided values" because it'll be one less thing pulling from Internet.
Set Screen Timeout to 30 Secs and Never have Auto-Brightness set, instead use a brightness toggle of some sort (Stock 'Power Control' Widget works well) to only have it as bright as you need to view in current conditions.
Open the Google 'Talk' application and uncheck the 'Auto log-in' setting, and then 'Sign out'. For some reason this always runs in the background and eats alot of battery.
If I think of more things ill post them
Hope these tips help, if they do don't forget to hit the thanks button thanks.
MoPhoACTV Initiative
There are many ways...
Switch on WiFi, 3G at only using, and close the not using application, decrease display brightness etc...
And if you root your phone, you may change CPU governor, or build.prop tweaks, script tweaks... Or change to custom kernel or custom ROM.
I forgot that 'LED's hack' is not available in the market anymore, I attached it below.
i hv just downloaded screen-filter lets c how that works...
Juice defender
Try JuiceDefender by Latedroid. It helps a lot to turn off things you don't need when you don't need them. Sorry I can't post the link- I'm new to XDA
my experience:
undervolting does not help much. you have to test a lot for only a little bit of improvement.
in my opinion you will not really remark it.
but what helps, i think, is set cpu speed, if possible. for example i use samsung galaxy s2 where cpu has max 1200mhz. i set max cpu freq to 800mhz. with a good rom (hydrogenics f.e.) android keeps running smooth with 800mhz and battery lasts noticeable longer.
I agree that undervolting doesn't help so much.
Like in up post, best thing to save Your battery is to change cpu power. You can also use diffrent cpu govenor : good for battery are smartassv2 and power save. Just need to have rooted phone and download app, fx. Antutu CPU Master or Set CPU. U can also make your cpu speed profiles.
Hi Guys,
I am using xperia sola from last twenty days.....:good: but the battery performance is very bad:crying: when i checked my battery usage, analysis came out that more than 50% of battery is getting used by display....so to cut down that i have started using picture wallpaper instead of live wallpaper but to my surprise i came to know that Live wallpaper is running in the background which is still consuming my battery.
Battery is lasting for less than 24 hours.

Task killer won't help, those tasks will come back and make it even worst for the juice they use for initation.
Disable data, or use 2G only (turn 3G back on when you really nead it). Or you can search in this forum the way to do it automatically .
For the live wallpaper issue, just uninstall it
Bright
You should try reducing the bright, Hight bright eats all the phone battery...

Screen brightness is going to be your number one killer. Also, if you're using WiFi/3G/4G all day long that will kill your battery too. Finally, if you're playing games that use a bunch of graphics that utilize your phone's hardware (openGL, unreal engine, etc.) it will drain your battery pretty fast.
I have seen an article somewhere saying that live wallpapers don't actually consume as much battery as people make them out to be, and i found this to be true, i got 5 days out of my Optimus 2X (no sim card inside) and it had a live wallpaper, what consumes the most battery is the screen itself (reduce brightness to get better battery life while using the phone) and data on 3G (i always turn off data when i don't use it) and i normaly get 2 days out of my Optimus 2X (1 day of heavy usage).
Thank you for the info whoever provided here.

Try or start with this app above and hunt for apps that syncing/updating in the background and basically you need to make a dumb phone out of your smartphone. Disable all autosyncs/notifications in the setting and apps like Facebook disable notifications. Open up Google play>settings and uncheck all default checked settings. Disable gmail/email notifications. Disable auto backup/restore. Disable all location services/vibrations/sounds when typing/wifi or GPS or BT when not in use. Disable data or stick with 2g in standby mode. Find a custom ROM that usually will be much better with battery management.
That's in a nutshell of how I can basically keep my phone draining 1% per hour on standby mode.

Free available n the paid one is awesome... I am not saying saying will get 100% increase but 30~40% INCREASE is observed by me and well something is better than nothing...

I highly recommend GO Power Master: https://play.google.com/store/apps/details?id=com.gau.go.launcherex.gowidget.gopowermaster
It lets you customize power profiles and set "sleep" cycles so that it uses minimal power when you're not using it anyway (I set mine to just be phone/text from 11pm until 7am).
It also has a "smart kill" button on the widget (which you don't have to use) that will prolong battery life by killing apps that are doing nothing. I know there's a lot of argument about app/task killers out there, but it's always worked well for me.
Adjust screen brightness to 0 (dim)
use dark wallpaper
disable gps, bluetooth , wifi when not in use and also air plane mode during night time
and also clear running apps with task manager:good:
Also you could try GSam Battery Monitor Pro, it will show you which process are using %'s of power
Try this one

Juice Defender functions only if you have you phone a lot of time inactive . . . It functions turning of your conections in inactivity period and olnly turns it on in few intervals depending of your profile . . . It's very good, but if you want your cell phone conected every time . . . this is not a solution . . .

Think I have a solution for short battery life for Nook! (Really for any android device)
The problem has been that the Nook Tablet does not go to a Deep sleep (even if they say its fixed its not). Every night I have to charge the Nook battery because it goes from 100% to 90% overnight. If the Nook sits all day with no use the battery will drop to 85%. Almost a 20% decrease in power in one day of no use. By the second day battery is down to 50% and forget it if I use the Nook.
This app seems to solve the problem!
I downloaded a free app (Google App store) called “CPU Tuner (rooted phones)” you need to be rooted but for most of us here this is not an issue.
This app allows you setup CPU speed, WiFi and other settings for different states the Nook may be in.You can setup several triggers but I only used 1. The problem is not just having the Nook go into Deep Sleep but to turn off other functions that hit the battery e.g. WiFi and sync. With this app you are able to tell the Nook to go into Airplane mode as well as turning off all other features that may consume battery life. Below is my setup and findings.
State 1: “On Power (Plugged in)” WiFi on, Sync on, airplane mode off and CPU set to 1020mhz Governor set to interactive
State 2: “On Battery” WiFi on, Sync on, airplane mode off and CPU set to 1020mhz Governor set to interactive (same as above)
State 3: “Screen off” WiFi off, Sync off, airplane mode on and CPU 600mhz Governor set to conservative
State 4: “Screen Lock” WiFi off, Sync off, airplane mode on and CPU 600mhz Governor set to conservative (Same as above)
With these settings (and having 3 nooks with CM10 to test) here are my numbers
test stared around 10pm
Nook 1 started with 76% batt (CPU Tuner not installed)
Nook 2 started with 85% batt (CPU Tuner not installed)
Nook 3 started with 90% batt (CPU Tuner installed)
checked battery life at 8am next morning.
Nook 1 65% batt
Nook 2 75% batt
Nook 3 91% batt (Yes it went up 1%)
Later in the day with no use 8pm still 91%
Loaded CPU Tuner on all three Nooks started test at 10pm. (Day 2)
Nook 1 started at 96%
Nook 2 started at 74%
Nook 3 started at 83%
Checked battery life at 8am next morning.
Nook 1 ended at 96%
Nook 2 ended at 75%
Nook 3 ended at 83%
As you can see this is a big difference then losing 20% power overnight. Since I have Screen Off and Screen Lock as the same trigger I don’t lose power if I am just checking batt level or the time.
This is a MUST HAVE APP. easy to setup and makes a big difference.
You can also setup it up so that if you are on the battery the CPU is at 1008mhz which will save battery life while in use and when plugged in CPU can go to 1020mhz giving you full power.
Sorry for such a long post but I felt it was good info for the users.

I do know it's a problem in some ROMs, and often a problem along the way during development. I think it's grocely unfair to suggest it's a general problem though.
I'm running a CM10 build from 1231 and I have not problems what-so-ever with battery life! I hardly loose anything while on standby (wifi off). I do turn it off manually, and I understand that with this app I can have it done automatically which is very neat, so might use it because of that. The processor speed adjustments works just fine anyway in the ROM i use.
It's great to know this thing exists and does work if I want to try a "work in progress" ROM more extensively. So once again :good:
The "battery-drain while asleep" problem got fixed since early December (e.g., Succulent's v12/08 build).
Also, I simply turn off WiFi (using a WiFi on/off widget) when I am not accessing Internet, and my NT's battery consumption while asleep has been well below 1% a day (comparable to that of my Google N7).
Finally, for those who are interested in battery consumption management tools, I find Battery Juice Defender (which I use on my Samsung GS-II phone) reasonably effective yet easy to use.
Sorry it was not meant to be a dig or insult!!!
I love ALL of the work that the developers have done and I think I have changed my ROM about a half a dozen times because I can't figure out which one I like best. But compared to my wife's Nook with just the B&N ROM her battery could last days where my battery only lasted 1 day.
Please; I did not mean anything insulting with the comment and the fact that these developers can put together such solid ROMs is saying something about their skills.
How I found this App was from posts here where users were saying that they had to turn off WiFi. Trying to make a WA or KA (WA = Wife Approved and KA = Kid Approved) I know that going in and turning on and off WiFi was never going to happen.
When installed the CPU Tuner and found that it was going to do this automatically and on top of this battery life goes from 1 day to several days I had to make a comment. Only after a few days of my kids using the Nook with the CPU Tuner they made comments about how long the battery lasted. Using these ROMs and CPU Tuner made the Nook 100% WA & KA and now wife is using Nook with the Hashcode ROM and I have heard no complaints. Happy wife, happy life.
Again sorry
Can you post screenshots of your settings from the start, there are some things in your OP that i can't get to setup for testing purposes, indeed the battery of my nook using @succulents ROM 4.1.2 final drains battery considerably while sleeping.

I have uploaded the screen shots. All settings can be changed after loading so if you select the wrong item its not a problem.
I try to keep it simple, You can have more then 1 configuration but as you can see I just use 1. I set my user experience to Normal which can be changed in the settings.
Once you start CPU tuner you will see the current state of the Nook. You can select a different state. (Note the battery was at 52% which has been at 52% for about 2 days and just charged it this morning.)
Next you will see triggers; here you set what Profiles you want for different states of the Nook. Just tap in that section. I forgot to take a screen grab. But I have battery at 100, "On Battery" = Normal, "Screen Locked" = Powersave, "Screen Off" = Powersave and "On Power" = Performance. "Battery Hot" = Powersave and "Call in progress" = Performance. I really only need two profiles Performance and Powersave my Normal has the same settings as Performance and my Screen Off (which I don't use) has the same setting as Powersave.
Next are the profiles. tap the profile you want to edit. See screen shot 7-10 these images have my profile settings. I don't trust airplane mode to really shut off all that I want off so I make sure that things I want disabled are disabled and when I go into Performance I disable airplane mode and enable WiFi (Not sure what Background Sync is or if it even works on the Nook most times I keep it off especially for the "Screen Off" and "Powersave" profiles)
For the governors I leave it as interactive for "Full Speed" and "Normal" settings and conservative for "Save Battery" and Extreme Save Battery these may be the default I am not sure.
If I wanted to really go crazy. I could set my Normal CPU speed to 1008mhz to save battery life while on battery. I could also setup it up that if I have 100% battery use Performance Profile and when the battery level drops to 70% use Normal profile (with CPU at 1008mhz) and when the battery goes to 60% then create a new profile which lowers the CPU speed even more. But with my current setup I am very happy and the fact that after a few days of no use the Nook still has the same power level from when I last had it on.
That's about it. If you have any questions let me know.

Is there any way to delay (eg I want it to wait 5 min before turning the WiFi off)? Or should I use tasker or automateit for something like this?

You can setup a profile where if you press the power button the CPU speed is reduced and turn off all features except WiFi. I believe that after 5 minutes (or what ever time you have set for "Sleep" I believe the default is 2 minutes) the Nook will go to sleep and all features for Sleep will take over e.g. No WiFi.
This will give you two Power options:
1. let the Nook go to sleep on its own after 5 minutes (Screen would be on during this time killing battery life)
2. Press the power button and screen turns off but WiFi is still on and after 5 minutes sleep all features off.
You can monitor what it's doing by pressing the power button and waiting about 6 minutes. Then go to the CPU Tuner log (shift pages to the left until you see the log page) What you would want to see is the following:
11:08am ALL-> Performance
11:07am All-> Powersave
11:01am All -> Screen Off
11:00am ALL-> Performance
Please note that since the time is only shown as hours and minutes it possible to see settings with the same time stamp.
Good Luck.
If you have any questions please let me know.
Fantastic, exactly what I am looking for :good:
I must say that the OP was very good, and CPU Tuner is a great app ....
but times, and apps move on.
currently I use the free "Battery Doctor" from Google Play which does what Tuner can do, but in a much user friendlier way.
my tablet only loses 1 to 2% overnight and still has 80% or so left if not used for a few days.
the developer also has a great file cleaner utility which i also use, and the Task Killer, and memory cleaner widgets you get.
in my opinion they are MUST have's, and I no longer even use the paid version of Juice defender that was my favorite app.

I'm running CM11 Snapshot M3 and haven't been able to find a user friendly way to automatically get wifi off during sleep.
The built-in "turn off wifi during sleep" setting does not seem to be working.
Battery Doctor (Battery Saver) doesn't seem to work well on this ROM. After installing, it would seem to let me change the screen brightness (the slider would move), but then it would revert back to 20%. The app then crashed, and attempting to run it again after rebooting results in a black screen of death.
I've tried a couple other apps like WiFi Auto-Off and Advanced Battery Saver - Free, and neither succeeded in shutting off wifi during sleep.
Granted, I did not try CPU tuner with this ROM. I've tried it in the past and found it very unfriendly.
Anyone have a user friendly method to automatically get wifi off during sleep on CM11?

I decided to give CPU Tuner another shot and it seems to work some of the time. I haven't been able to figure out what the difference is between the times it works and the times it doesn't.

I just use the available quick toggles in CM11 to manually (1) switch off WiFi and (2) go to sleep.
Yes, there is a quick toggle for go to sleep.
I've pretty much have gave up on ever having great battery life on my Nook. Just the nature of the beast Still a great little tablet
Since all those apps automate disable wi-fi when system sleeps and you won't get any notifications if android apps. try to poll data from internet, I just set wi-fi to automatically turn off in android wi-fi advanced menus, there is no need of any of those apps since android system can do the same thing.
Nookt Tablet goes Nuts less than 50% Battery
Currently running CM 11 snapshot 5
Whenever my nook gets below 50% battery it goes nuts. apps open themselves, then shut down, windows open, if I am watching a video it stops then begins at the beginning. Weird.
Have had this issue before and was hoping with the upgrade it would stop, but no dice.
Help?

I have the same issue with my Nook Tablet. I will get to about 43% and it flips out. Apps opening, settings opening, Apps close, airplane mode comes, etc. I have to plug it back in to undo the mess and continue using it. I've had this issue with AndoidForNook's builds as well as the CM-acclaim 10.2.1 build.

Thanks, glad to know it's not just me and I don't have a real "ghost in the machine". I use my Nook on the train everyday, couple times a week I have to pull out an external battery to keep it going.
