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?

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.

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.
Wondering if this is how it's designed or what... but when my my tablet is docked to the docking station the screen never seems to go into standby / sleep mode. Is there a setting that I am missing or is it designed that way?
Funny you should mention that. I've started wondering today if the tablet won't go into Deep Sleep if you just close the lid.
Try pressing the power button first, then closing the lid, see if that makes any difference.
EDIT: Also, do you have the battery saving feature enabled, so when you press buttons on the dock, it doesn't wake it up?
There is a big discussion going on in another thread and AFAIK it is known issue for some Docks and Asus would replace it for you.
But first please ensure that the settings/apps are not stopping it from deep sleep.
Well... I finally figured it out. Totally my fault that I didn't realize what was going on until I was restoring my phone (EVO) and saw the item...
I had "Stay Awake (Screen will never sleep while charging)" enabled in the settings. It never occurred to me, because the dock is charging the tablet, it is always in "charging mode", thus it wouldn't go to sleep because of that.
Once I un-checked that, it went to sleep perfectly fine... although I still feel the battery on the dock drains a little faster than it should, it's def better (and not nearly as fast as the drain issue people were having).

D'OH! For crying out loud - thank you! This post saved me a warranty call to ASUS. I would've felt like an idiot returning my dock for a dumb setting I missed.

Here is a tip for longer battery, with no WIFI when screen off i noticed when looking at my battery stats that wifi was always on longer. It wasnt turning off straight away.
I now disable the wifi using the dock button then turn off using the power button on the tablet just reverse the procedure when turning on.
HTH
Anyone else using the app Auto Airplane mode? It is a cracker of an app for battery life on standby (got 3 days of sporadic use, about 4 hours, and still have 49% batt left on the tablet). However, I am finding that the tablet lags really badly after waking up from a couple of hours or more of screen off time. Really bad lag, lasting at least several minutes after wake up. I get sick of the lag after 5 minutes or so and cold boot it, which completely fixes lag. I know it has to update apps, mail etc after wireless comes back on, but this probably shouldn't take minutes to do. Anyone else experiencing this problem? I want to keep the app, but I need the tablet to be responsive when I wake it up, cause I use it at work to take notes, make appointments etc.
Cheers,
Mike.
This app was great in the early Prime Firmware, but is no longer necessary. There are 2 seperate places in settings that give you roughly the same thing. Go to WiFi, hit the three dot menu, select advanced and "Turn off wifi during sleep" I prefer the "only keep wifi on when plugged in" option, but you can choose never or always. Second, in Asus Custom Settings, you can stop all syncing while in sleep mode. This will also cause the tab to do some updates when you wake iy, but I wpuld look into just how mich crap you are actually syncing if you are seeing that kind of lag. Go to accounts in settings and sellect each account, especially the Google primary account, you will see what apps are syncing here. Get rid of auto airplane mode app. Its niche has been filled by stock firmware, with the exception of GPS, which does not shut down in sleep mode without it. Its a little more effort to manually contfol it, but getting almost the same benefits with a stock firmware option is always preferable in my opinion. Consider: The auto airplane app has to run in memory, thus consuming SOME battery, though it's likely negligible.

Disclaimer: I searched the forums but couldn't find anything relevant.
Am I the only one whose tf700 acts really sluggish after it wakes up for a minute or two?
Is there any solution to this? It kills my main use case of the tablet (pick it up when I want to look at something in a pinch, and put it away when I'm done).
I'm on official ROM, rooter but not unlocked. This has been happening with the previous firmware versions as well.
I had the same problem for a while... most of the time I woke the tablet from sleep it'd be very sluggish.
I noticed that this happens when the wifi disconnected during sleep... it would have to reconnect and therefore all the services that required wifi would all start at the same time, throttling the system.
Turns out its the special setting in ASUS Customized Settings, "Disconnects network during sleep" that was causing this. It does exactly what it says, suspends network-related tasks when the screen goes off and resumes on screen on.
I initially turned this on because i was worried network tasks would drain my battery on sleep, but there doesn't really seem to be much of a performance difference with it on or off. So I'm leaving it off for now.

Also try a clean boot.
Hold down the volume down and power button when you power it on from cold. Let it go through the next screen without touching and it will clear cache automatically.
This does help as well anyway.
It's probably still quicker than most of us after we wake up..... Have you tried coffee?
Try turning off all bloatware. Mine used to be incredibly sluggish when waking up, and when I checked it turned on about 25-ish apps everytime i woke it up. Rubbish like Google Now, Talk, Gallery, etc. This slows the poor thing down to an insane level. Turned off all the random crap I would never use anyway, did a coldboot (sbdags describes the process up one post ^) and now it's instantly awake.
This problem started with v20 for me. When ever I put the tablet to sleep and leave it for an extended period of time (overnight, or all day while im at work) and I press the button to turn back on, I find it has turned off. I have to long press the power button to boot the tablet. This does not happen if I wake the tablet within an hour or so. The battery will be anywhere from 30-70% at this point also. I have tried going back to v19 and 4.3 without solving the issue. I have done full wipe/format with TWRP (latest) multiple times and get the same result (I do full wipe/format for every install I do regardless). I have set the min cpu to 3xxmhz also.
I am at a loss here and hope that the tablet itself has not just reached EOL for me. Some other install notes, I have tried to install rom/gapps and leave it as is, and I have also used Tibu to remove stock email, search, and keyboard (which is my usual install routine) with the same results both ways.
Thanks in advance.
New info, I left the tablet plugged in while at work yesterday and it did not shut down while in sleep. Also, it did not shut down last night while off the power. I'm hoping for a repeat of this performance today since I left it off the power supply, and it has 50% battery when I left this AM.
Try setting minimum CPU state to 312MHz in settings > performance
Make sure to check the "Apply at boot" box

I have the min cpu set to 312MHz already, will double check the set at boot box. Also last night I set the wifi to turn off while in sleep to see if that makes a difference. Yesterday morning I had left the tablet at about 50% battery in the morning and when I got home about 10hrs later it had drained the battery to the point of shut down and I got the red battery symbol. So I think there may be something draining the battery that I don't see. I will check battery stats tonight to see where I am at with those.
With wifi off while asleep, the tablet is running perfectly. I had already increased the min cpu to 312MHz and that didn't fix it. Now that the wifi turns off on sleep there is no more battery drain while in sleep, or shut downs while in sleep.
I don't under stand why just with 4.4.2 the wifi is draining the battery so much on sleep. I only sync Calendar, Contacts, and Gmail on the google account. The same as I did before with 4.3 roms. I will play with it more tonight if I have time and try to see in stats what is using the battery the most.
