Turn off 3G, turn on only when needed
Settings -> Location -> Untick ''Wireless Networks and GPS Satelites''
Settings ->Accounts -> Untick Background data (Unless you want to use market)
Settings -> Wirelless -> Advanced -> Wifi sleep policy -> Never
Use phone on 2G, unless using internet (then switch to 3G mode)
Data traffic always OFF (Use only when needed)
Backlight low or Auto Brightness (And allow light to decrease)
Turn off wireless, basically everything turned off with the power control widget, turn on when necessary
Install task manager and set auto-kill mode to crazy on switch off screen mode (Put apps that always run in ignore list e.g. Launcher, Messaging. Basically the necessities)
Install SetCPU (After rooting your phone) - Min CPU 122mhz, Max CPU ~700mhz - 'On demand' profile
SetCpu - Profiles -> Screen Off -> Min 122mhz, Max 122mhz, Performance mode
Upgrade to Froyo 2.2 - Enable JIT (Saves battery on 2.2+)
Switch to a Cyanogenmod Rom
Enable undervolting (Only for CyanogenMOD roms)
Use RenderFX widget (CyanogenMOD, best to use low red, best to use when you are heading out)
Cyanogenmod - Spare Parts -> End Button Behaviour -> Go to sleep
LAST, but NOT LEAST, if you notice no significant increase in battery life, then your battery is no calibrated right! So go to market, download 'Battery Calibration', and charge your phone to 100%. Next, if its abbout 4000v - 4200v, your phone is correctly calibrated!
If its not 4000 -4200, press the ''calibrate'' button, and let your phone die out, then fully charge it (while its still powered off). Wait till light is green, TURN ON.
After boot, battery will not be 100% yet, reboot once more, charge to 100% (while phone is on), and check your new calibrated battery! It should now be 4000 to 4200v
I know there might be programs and applications to increase your battery life, but I dont have any experience with these, so feel free to post your experiences! Some examples may include juicedefender, etc
Anyone wants to add to this list, feel free =)

I don't know what goes wrong, but mine losts for only one day. If i have charged it overnight the battery is empty the next evening
No task managers. The phone manages its RAM well and the battery will last longer. For normal uses upto 1.5 days and for heavy users 1 day.

and here I heard installing juicedefender does more damage than good too.. what to believe? Everything is based on peoples hearsay and no evidence..
On my girl friends X10 mini I changed from ADW launcher to Helixlauncher and changed the brightness to auto. That made a HUGE difference.
Was on vacation and turned off 3G because I was not gonna use any expenisve data. That alone boosted my batterylife about 1 days worth.

people can do much to boost battery time, like turn off 3g, brightness control, turn off gps and so on, that all helps the battery
I have switched of almost everything and still get about 1 day of battery with about 2-3Hrs of music and a few calls and videos.
is it ok?
I get over 48 hours and I use the wifi a lot and do about 30mins of calls a day.
My tips:
* turn background data off and manually update ur emails when u want - this is the best tip I put it on my blog too
* manually enable network data when u need it
* use the top button to go on standby as soon as you are done using the phone
* keep gps, 3g and wifi off unless u want to use it
Sent from my U20i using XDA App
I have background data off.
No emailing whatsoever till now....
Almost 75% of the time in standby
Gps 3G wifi bluetooth are off.
Yet with stock launcer i get 24Hrs
Helix 30Hrs..
Why?
Its been two weeks(or 3) since i bought the phone...
Please reply.
BTW when did you buy the phone?
^^Ok.
I have come to know the problem.
Running any apps in background like Battery Indicator or task manager brings down the battery so much(the latter not much though)..
Because daily i used to get the above with battery indicator pro on.
But after uninstalling it i got about double that battery life..
So people better don't run them all the time.
task manager can be used sometimes about once every 2 hrs o so.
This increased my battery life so much on stock launcher
Just got the pro today. Will be ditching my X2 depending on the performance of this one after a week. So far, I love the mini pro for the fact that I can now hear my incoming messages and calls!
A couple of questions though:
1) Is there a way to wake up the screen when an SMS arrives?
2) Custom ringtone per contact?
3) Is there a way to disable screen lock when the phone goes to sleep by itself (not pressing the power button) ?
4) Is there a way to unlock the screen without the need to press the left button, I was hoping to go directly to the pattern unlock after i turn on the phone
Still getting used to the keyboard lay-out as I've been using X2 for almost 6 months.

I use Chomp SMS app and this allows the screen to wake-up, I think Handcent SMS does too. I never used the stock SMS app so not sure if there is a way to do it with that.

Not sure if this answers your question, I just press the Menu button twice to unlock the phone, never used the power button to wake it up funnily enough, only used the power button go in to sleep mode. When I press Menu button it wakes up to the pattern unlock.

Nice, i'll try to look for those apps. I did try the menu button and it worked. At least this relieves stress on the power button since I won't be using it to wake-up the phone anymore.
How's about not locking the phone when it goes to sleep? Unless I press the power button?
After a day with it, battery is now @ 30%+. Hope it improves or SE comes out with a high capacity.
Hi, where is the disable 3G button?
I can't seem to find it. I found wifi on and off.
and I unchecked location with gps.
thanks
Helix launcher is the best thing I installed to my mini pro. Batt life is now 3-4 days regular use and 5 days if i don't play games. Games are draining the batt quickly.
I'm totally getting rid of my X2.
3 to 4 days? Lol how can that be possible.. Did you use 3g?

I can prove it, there's a display in the phone where it says # of hours unplugged. If it's not working for you, doesn't mean it shouldn't for others as well. If you barely make 2 days, then that's what we should be LOLing about.
My setting is as follows:
- 2g only
- 1 to 2 hours of wifi and bluetooth per day
- 1 to 2 hours of games (love the games) per day
- tried GPS for 1 hour using mapdroyd
- a couple of calls and text messages per day
- tried watching a movie (AVI) for an hour using yxflash
- tried the media, played MP3s for an hour
- tried meebo for an hour
- I got my alarms ON always
- notifications ON always
- custom led lights for new SMS (using ringo pro) always
- max volume for the entire day
- medium volume at night
- data connection off
- background data off
- screen brightness to zero but the sensor is still working (weird), the screens still adjusts to the surrounding
This is after installing helix. Before helix, I got a max of 1 and a half days only.

So I have set my power saving mode to come on at 30% and for it to disable everything except wifi. The problem is that after I charge my phone back up, those settings remain disabled even though power saving mode is turned off, so I have to manually enable them each time. Is there a way around this?

What ROM and kernel is on your phone?
If you enable user specified power saving with your customized settings (30% battery => shut down everything accept wifi), and you did not disable this power saving mode, when exactly is the power saving mode disabled?
As soon as you plug in the power cable?
And is it not re-enabled automatically, after pulling the power cable out?
Sorry, but I did not exactly understand your issue.
"those settings remain disabled even though power saving mode is turned off" => Yes, that's correct. If the power saving mode is turned off, all power saving settings should be disabled.
This sounds to me like "normal" behavior.
Maybe I misunderstood something in your description.

I'm on stock 2.3.3 and KG2
And I meant that these settings do not revert themselves after I finish charging the battery. For example, at less than 30%, my power saving mode turns off syncing. But once I finish charging my phone back to 100%, the syncing is remained off, so essentially, my power saving mode never really turns itself off even after charging.
I noticed the same thing - it's very annoying to set my screen timeout to 2 minutes, and when power-save mode comes on, it gets reset to 30 seconds and stays there.
I ended up turning off almost all of the power-saving features, and setting the threshold to 5%. I'm running the stock rooted kernel with NoCIQ, so I already have a pretty substantial battery life (~24-30 hrs with normal usage and wifi at home).

Have a look at MyProfiles app from the Market.
Maybe it can help you to switch between different profiles based on system triggers.
Or use AutomateIt app to define rules when to toggle wifi, bt, gps, etc.
Just worth a try...

Thanks for the suggestion, but I kinda want to get to the root of the problem here as opposed to installing an app to mask it. Does anyone else know what's wrong with my phone?
There's nothing wrong, that's just the way it works, it change your setting when activates but doesn't change them back.
I no longer use it, since I have GPS/wifi/BT disabled unless I use them anyway.
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.

Terrific recommendation. Was easy to set up and works like a charm. No more finding my Nook with a flat battery after ignoring it for a couple of days.
Gracias! :good:
Thank you for the tip! I will make a note of it so I can use it if/when I need it! It seems very handy to be able to set upp different user schemes!
However, I do not agree with this comment:

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.

V;
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 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.

If you face problem with battery.. draining like hell..
then these tips are for you....
1. Battery Calibration
2. Control Apps
3. Device Setting
1. Battery Calibration
Don't use any application..
Just charge your battery till 100%.. Restart your phone
without remove charger..Important
after restart (battery show 60 to 98%. leave it on charge again till 100% + 2 hrs. more
Then remove from charger & use phone until battery drain to 0% and switch-off itself
Don't recharge between 100 to 0%.. then try to restart at least 3 time.. to sure drain battery completely
now connect your phone to charger.. after 10 minutes start your phone.
but don't remove your charger till battery goes 100%...Important
(sometime it take more than 4-5 hrs. so better in night) When battery goes 100% ...now you done Calibration..
Technically..
on every restart Android reset Battery (by wipe battery status)
So.. on 100% Android make Maximum level - on 0% minimum level
P.S. Do this calibration on every ROM flash or at-least one time a month..
2. Control Apps
Some Application consume battery do much..
i.e. Facebook, Youtube, Maps, Whatsapp, Viber, Yahoo! Mail / Messenger, Skype, Hotmail.com, etc.
so when you don't use these apps (running in background) kill them .
Better use Browser Bookmark instead applications
i.e. Facebook, YouTube, Yahoo! Mail, Yahoo Messenger, Outlook,
It help to save your RAM also..
3. Device Setting
lowest brightness..
lowest screen timeout
Close WiFi if no need
Close Data Conn. if no need.
Close Bluetooth if no need.
Close GPS if no need.

If you face problem with battery.. draining like hell..
then these tips are for you....
1. Battery Calibration
2. Control Apps
3. Device Setting
1. Battery Calibration
Don't use any application..
Just charge your battery till 100%.. Restart your phone
without remove charger..Important
after restart (battery show 60 to 98%. leave it on charge again till 100% + 2 hrs. more
Then remove from charger & use phone until battery drain to 0% and switch-off itself
Don't recharge between 100 to 0%.. then try to restart at least 3 time.. to sure drain battery completely
now connect your phone to charger.. after 10 minutes start your phone.
but don't remove your charger till battery goes 100%...Important
(sometime it take more than 4-5 hrs. so better in night) When battery goes 100% ...now you done Calibration..
Technically..
on every restart Android reset Battery (by wipe battery status)
So.. on 100% Android make Maximum level - on 0% minimum level
P.S. Do this calibration on every ROM flash or at-least one time a month..
2. Control Apps
Some Application consume battery do much..
i.e. Facebook, Youtube, Maps, Whatsapp, Viber, Yahoo! Mail / Messenger, Skype, Hotmail.com, etc.
so when you don't use these apps (running in background) kill them .
Better use Browser Bookmark instead applications
i.e. Facebook, YouTube, Yahoo! Mail, Yahoo Messenger, Outlook,
It help to save your RAM also..
3. Device Setting
lowest brightness..
lowest screen timeout
Close WiFi if no need
Close Data Conn. if no need.
Close Bluetooth if no need.
Close GPS if no need.
try to use dark backgrounds..

Just one comment on your procudure.
The text as you wrote:

Io-li batteries cannot be fully discharged. POwering up mobile at 0% (withou charger pluged in) just to exaust battery can lead to a permanent battery damage or shortage in its life.
The rest of the procudure may help (or not),
Is there a way to turn off the notification that says the phone is too hot to charge? I am trying to use Google maps whole charging and the notification keeps popping up and I can't see my screen at all. I need it charging because on long trips the phone would die since maps drains battery fast.
It would not be wise to try and disable that notification. Also how is your s9 overheating? I have never had any heating issues even when im at full brightness, playing music and running google maps at the same time in my car. I recommend putting all your apps to always sleeping in the device maintenance battery saver setting, this will ensure that no other app is doing something crazy in the background and maxing your cpu out. Putting your apps to always sleeping does not disable important notifications such as facebook messages or post updates but will disable apps access to your phones sensors when they are in the background for a couple of minutes, such as step count from galaxy health but u can just not add those apps and they will continue to work fine.
Well I don't want to disable it because I know it will be bad for the battery I just don't want to see the notification because it takes up the whole screen and when I tap it to make it go away it comes back in seconds and I can't see my phone screen
Make sure the phone is fully charged before starting Google maps. It won't get hot then.
Are you using a wireless charger? If so, switch to a wired one. It will generate less heat. Is the phone positioned so the sun is shining right on it? What's the output of your charger? Maybe try one with lower output. I've run Maps on my S9+ while charging many times without issue.
Unpack may be on to something with the idea of background apps eating up battery. I drove from northern VA to southern Delaware (~ 3 hours) using map to navigate without plugging the phone in, and still had close to 50% battery left.
i got pretty good battery usage without high temps. had my phone in power saving mode (limited cpu) and lowering maps accuracy to battery saving.
