I'm a truck driver and I'm a heavy user.
I did too before I made the changes below. These all work with the Stock Rom.
1. Installed No Lock (so that I don't have to swipe the screen to unlock, just push the power button)
2. Set screen to turn off in 30 seconds.
3. Installed Brightness Widget (allows changing the brightness from the home screen
4. Installed Screen Filter (lets me really darken my screen at night.
Try those and see how you do.
5. I then flashed the Infused Rom (I now get up to 10-14 hours)

Also, Turn off GPS and Wifi when you're not using them.

Battery
After much experimenting and monitoring of battery use I find that the biggest drain is the screen display, so go to settings-->display-->brightness and lower the screen brightness as low as you comfortably can. Also when you you are not using the phone make sure the screen is off, I have trained myself to automatically hit the power button every time I put down the phone. If you listen to music through your phone make sure the settings on your music players allow the phone to play when the screen is off and turn the screen off while it plays.
GPS also drains the battery, so I keep it turned off when I don't use the Nav. When I use the Nav I know the battery will drain at a rapid pace, nothing you can do there, even if I have the phone plugged in to car power while using Nav it still drains the battery! Drains slower than unplugged navigating but still drains.
If your watching videos then your S.O.L. there's really nothing you can do that will increase battery life enough to make a difference during video playback.
I get 10-12 hours with regular use and stock rom. Worst was 8 hours best was 24.

Thanks for all the advice this has really helped my battery

3. Installed Brightness Widget (allows changing the brightness from the home screen
There was a recent post that showed a shortcut for changing the screen brightness from the homescreen without any additional software. First, turn off auto brightness. Second, tap and hold the menu bar at the top. Third, slide left to reduce the screen brightness and right to increase screen brightness.

How does it drain your battery when its plugged into the car? I have never seen that on any cell phone. That my friend is messed up if true.

It seems that Samsung ****ed up and included phone CPU/screen/etc usage when measuring battery charge current.
This means that the 600 mA stock battery charge current limit isn't just going to the battery, it's split between battery/screen/CPU. If screen/CPU/etc go above 600 mA (Navigation at full brightness seems to be the most common way), battery starts draining.
It also means that unless there's something I'm missing (which I could be since the MAX8998 datasheet is super-ultra-secret), our phone isn't going to be able to do proper charge termination - if the screen is on/CPU is running, it will cause a falsely high battery charge current reading, which will cause charging to fail to terminate.

Juice defender
I found that juice defender helped my battery and i just use the free version it's a great app

I used Iphone 3g 3gs 4. None of them drain battery like this one. First time use Android phone and getting a bit disappointed of this phone. It's draining 2% every 5 mins and im using stock Rom.

Install a ROM. Infused v2 nearly doubled my screen-on battery life and tripled my screen-off battery life.

look in about phone battery use to identify the biggest battery user, it should be the screen. anything else and there is a problem.
the cell standby may go high on froyo rom, turning on flight mode and turning it off will correct that, it's an android bug.
on gingerbread the android os or android system may hog battery occasionally. some think it is the wifi sleep policy but it pops up on me without setting the sleep policy. the fix for that is to pull the battery for a couple minutes and put it back in and restart the phone.
next manage the screen brightness
install a custom rom, there are issues with certain firmware keeping sensors active wen they shouldn't be.
turn off unneeded sync options (i find that auto fetching my email uses a lot especially with my gmail already set to sync),
use wifi when you use the internet if possible, turn it off when out and about.
monitor cpu useage of apps that are cached in the task manager
kill apps that use cpu
if needed turn the max cpu clock down to 800mhz
set "use wireless networks" for location when possible for general location (limited to city level at times)

Actually, high cell standby is OK if the phone is screen-off often.
Cell standby is always my top user - but my phone is sitting on my desk with the screen off frequently, in a location with weak signal. Weak signal makes cell standby usage go WAY up.

Syncwifi application is awesome for extending sync settings to gain more battery

Using titanium backup I froze drm content 2.2.1 and this significantly increased my battery life.
Sent from my Infuse. It is what it isn't.

JuiceDefender!!
I agree JuiceDefender works!! I had to charge in the middle of the day. Now with moderate use it will last all day Im on stock Rom.

I easily get 2 days out of my Infuse, no idea how some of you are managing to only get 8 hours. After rooting my phone and freezing the bloat i easily get twice the battery life of my prior iPhone 3GS.

airplane mode shortly after bootup

I recently installed miuig2x-1.8.19 on my LG 999 however after about 5 minutes airplane mode come on. The only way to fix is battery removal. But them again....it only lats about 5 minutes.s
Anyone got any advice

Same issue here. Lucky me though it lasts most of the day before going to airplane.

Sounds like a way too aggressive power saving setting. Does MIUI have a power saving program built in, or did you install some kind of battery saver program?

Battery dies over night.

I use awesome off to turn my pad on and off so I don't have to use the power switch all the time. I always do this so I don't have to go through the whole boot up process when I want to use it. I noticed that when I wake up in the morning the pad is dead or almost dead. Is there a better way to put this to sleep at night? There is always so much stuff running that kills the battery. I read on here somewhere that someone was not even losing 1% by putting it in some deep sleep. Is there a mode for long time sleep that does not use battery or run any processes? But without shutting it down all the way.

Toasted Marshmellow?
Can't you just set the tablet to sleep in 5 or so minutes after being inactive?
You can have the tab cut wifi off in sleep also.
I don't do the wifi off in sleep tho...sometimes it doesn't reconnect after a wake up.
I don't know what awesome off is...I'll have to check that out.
My tab just goes into sleep after 10 minutes when I set it down.

The problem is awesome off. It won't let the pad sleep and is constantly checking for movement, light levels etc. Dump it and use the power button to turn it off and on.

I have Nook color power button donate that I got when I had my old rooted Nook color with flaky on off switch. It was in my google apps when I was loading apps on my infinity so I figured try it and see what happens lol It works remarkably well on my tab and does put it into deep sleep . See attached. I have not used my tablet much in last day but you can see that it does put it to sleep and turns wifi on and off and also reboots. Also BTW I then tried it on my rooted ICS leak Bionic and it gives reboot function instead of the long drawn out shut down then turn on process. It does not speed up any of these functions as far as rebooting.

Could be the "wifi location drain"-bug with google maps. From reading the forums it seems quite a few people have it without knowing it. You can of course disable wifi while sleeping, but this will not cure the main issue.
Turn the location settings on in google maps, then make sure that unneeded check boxes are disabled under location settings menu and you should be fine after that. The interesting part here is that google maps will drain the wifi even when the settings are not enabled, perhaps because you can't access the underlying menu without first enabling it. So only after you first enable this setting in maps will it work correctly.
Hopefully this helps, it did for me ..

Yoop,
I watched the awesome off YT video and it didn't look as though the tablet was being sent into full sleep.
I guess with it just grinding away essentially not shut down into a battery save mode it would die.
Doesn't the Tegra3 have a 5th core for minimum power processing or fast wake up?

how to get full brightness on low battery?

when my battery is low the tablet dims. how do I remove this setting?

I would like to know this too. I realize it's a safeguard because a complete battery drain sucks for this type of battery, right? But a forced always dark kind of sucks compared to a warning forced dark that you could change back.. feels... Appley.

Hi you two, all you have to do is go into settings and then you should see 'Power Saving mode' Under storage and above battery. Simply turn on power saving mode momentarily and then you can untick the screen power saving mode and then turn off power saving mode if you wish to.
This is on the settings for JB, I dont know if this will be the same as the ICS settings, if not just have a look around in settings. It should be in there somewhere.

no effect changing that settings
I already have done this: "all you have to do is go into settings and then you should see 'Power Saving mode' Under storage and above battery. Simply turn on power saving mode momentarily and then you can untick the screen power saving mode and then turn off power saving mode if you wish to."
However, my screen stays gray and i can't see nothing more bright... my device is a samsung galaxy note 10.1 gt-n8010 with android 4.1.1 and kernel version 3.0.31-541027
Any help appreciated because this is very annoying.
Thanks,
Miguel Real.

In the same boat here, anyone have a solution?

I was wondering the same thing

Did anyone ever find a solution to this? The screen dimming is a pain in the ass. I'd rather burn the last few minutes of power at full brightness.

This is my only problem with this tablet. I would really appreciate if anyone came up with a solution to this

I guess there is no fix without rooting? Bummer. Some things about this tablet are just so blatantly annoying I can't figure what the designers were thinking.
Hopefully the kitkat update will provide options.

It is protecting the battery. You dont need to drain your battery empty on every cycle - and it is only making bad to the lithium battery to cycle is empty-full all the time. The problem with lithium battries have, is that if the battery drains too empty, it wont start to charge. It is dead. There are safety mechanics to prevent this to happen, auto power off/shutdown features though... But when the battery is 5%, it turns the display dim to get you more time to plug it in. So, if you want to keep your battery good, dont cycle is every time from full to empty state. And dont let it to auto shut off, it may go too empty and the battery wont start to charge anymore.
It is a built in feature and Kitkat wont change this.

Android seems frozen with black screen

Android 9 on a Samsung SM-T290 tablet.
Had used my tablet, turned off screen (click Power once), and put it down. Some unknown time later, picked up tablet, clicked Power once, screen did not come on. After clicking Power a few times, held Power down thinking somehow tablet had shut itself off completely. Instead of booting, I got the choices "Power off / Shutdown" and "Reboot". Shutting down and rebooting worked. No sign of problems.
Some time ago I noticed my Uptime seemed large -- I think 400 to 600 hours.
What would cause Android to get itself into a state in which it is still running enough to offer a Power Off menu, but in which it refuses to light up the screen?
In particular, is there any problem with running too long without shutting down and rebooting?

My guess is that in your Android the Doze mode is enabled.
FYI:
Starting with Android 6 Marshmallow, the Doze mode feature was introduced. This feature is designed to give a new breath of fresh air to battery consumption and in general battery life.

No match when I Search Settings for "doze".
Under Battery -> Settings there is an
Optimize settings​Save battery by optimizing your settings when you are not using your tablet.​It's a toggle, it is toggled OFF.
I think at the moment I turned off the sceeen, I was im a browser on an obnoxious web page. Maybe their clever Javascript tied something into a knot.
I'll try to notice when I pass 600 hours of Uptime.

If it has the doze feature, it would be a background process that you would see no controls or settings for. It is a feature in the kernel that runs at and below system level and you can't "see" it if you look for it.
Doze puts the device to sleep, it effectively freezes everything from the kernel level all the way up through system/user level and turns everything off without actually powering down and stays in that state until you "wake" it.
An example would be a Kindle Fire HD tablet that I had with doze, I forgot it was on and running a PSP emulator and I put it in a draw for many weeks, when I pulled it out of the draw and hit the power button, it woke right back up straight to the enulator and the game I had running and still had 60% battery.
