Does enabling wifi when on standby drains battery, even if you're not connected?
I made some registry changes yesterday and I also enabled this with wifi, and I woke up with 20% less battery, normal for me is 7-10%.
I can't figure it out what I did wrong except if wifi is the problem?
yes if your wifi is on it will consume more battery. check if your mobile is constantly checking for new mails or updating the weather. disable them if you want your battery to last longer.

I would like to disagree completely. I've already ran rigorous test just to prove if it does or not on MY HD2. And let me tell you that it does not. YMMV.
It eats just as much battery as if you're using it but without the display on. So in any case, it eats less because the backlight remains off.
Using DsE V6.5 ROM. I got my battery to drain 3% every 12-15 minutes leaving Weather to update every 30 minutes and Send/Recieve new Mail every 5 minutes, Have pandora playing in the background and leaving web browsers opened, google maps activate.
During my test, I recorded the time and the % drop. I started at 9AM @100% and Dropped to around 3:30PM to 7% battery left. Now remember, this is a constant run without turning the device off, never turning wifi off and without exiting any windows. Also, Ive set my device to dim the screen after 1 minute and let it blackout after 2 minutes. Just take note that every time I picked up my phone to change a pandora station or read a new email, I never push the "end" key to let the screen go blank instantly. I let it do its full 2 minutes thing and let it go blank automatically.
This is just so I remain very rigorous!
This has helped me understand a lot about my battery and how much I can pull it out during a full days or usage.
I noticed that My battery can last up to 6.5 hours of basically, NON-STOP usage. Just image if I turned off wifi and only needed it the moment I wanted to check if i had new mail, etc. My battery would last ALL DAY.
FYI, under normal use, my battery is around 55-65% by the end of the day under moderate use.
I have updates every 6 hours for weather, but I can see it connects to 3g when is the time. This is not the problem.
The problem started yesterday/today when I made some registry changes...I enabled 24bpp colors and I turned vsinc off.
I am not connected to wlan, it is turned off, I only enabled the option "enable when in standby" if I sometimes need it when phone goes in stand by.
I am asking...does enabling ENABLE WIFI IN STAND BY eats battery when NOT USING WLAN AT ALL?
Thanks
I have epic 4g now for a week. Its still not activated, just sits at home connected to wifi - while I use touch pro2, awaiting sero plus on oct 1st.
There is push sync with hotmail and google. I get home and play almost constantly with the phone from 5 to 11pm - testing new apps/games, reading twitter etc - before I get low battery warning.
My biggest surprise was that the SCREEN (supposedly high efficency AMOLED) is draining more than 40% of the battery! Not the wifi, not the cpu or whatever else is inside. This is with default power managment settings.
What numbers do you guys get in the end of the day? What are you using - 3g,4g,wifi,gps,apps?

Sometimes mine goes as high as 72%, and that's the screen alone, and i have the brightness down all the way to zero (and even at zero it's still plenty viewable).
Definitely the screen is the biggest battery drainer. I've NEVER seen anything higher usage than the Display. Its usually in the 60-80% of battery usage.
And I keep the power to the lowest setting on a daily basis.
The screen is always the biggest offender. Usually in the 70%+ range with brightness all he way down. The samoled talk is just marketing bs. Maybe better performance when the screen is black. Unfortunately all black backgrounds happen to be the minority on websites, applications etc.
Display used to be the main offender on my phone (60-70%) but since I upgraded to DI07, Cell Standby is crushing my battery. The airplane toggle doesn't do ****, had to buy a cable so I can plug it in at work just so at the end of an 8hr day I have more than 30% battery left even with JuiceDefender running. Getting pretty frustrated.

I have this exact same issue. Cell standby is killing my battery. Right now I have 18% time without signal... it has been as high as 25% before. I never had this issue before DI07.
Cell Standby is 41%, with Display at 32%, time without signal is a whopping 50%, and I get near-full to full bars at work and about 2-3 at home.
my cell standby was over 50% after the update. I went in and changed my call setting>System select and chose "sprint only" which will not allow the phone to roam, but it got rid of this battery drain. I have a lot more battery now. But i will have to turn it back whenever i loose service. There's got to be a better way to avoid this thing always looking for the GSM towers when it's a SPRINT PHONE and should for CDMA unless there's no signal. I don't understand how they allow such a dumb issue to haunt tihs phone.
My current numbers:
Cell Standby: 34%
Phone idle: 25%
Display: 17%
Android System: 10%
Email: 5%
Maps: 3%
Dialer: 2%
Wi-fi: 2%
Android OS: 2%
Cell standby has gone up for me since the update, but my last charge was actually the first time I saw any significant "time without signal", and I think that was because I had 4G turned on all day. I have it turned off now and that number is back to 0%.
I'm learning some tricks to keep the battery charged on this thing. Yesterday I managed to go all day from waking up to going to sleep without charging (around 18 hours, though I rebooted at one point so I'm not sure the actual total) and I still had about 1/5 of my battery gauge left.
I've found wi-fi makes a HUGE difference. I have wi-fi both at home and at work, and that's probably 80% of an average day for me. Wi-fi drains the battery *much* less than 3G.
I have my screen turned down not to 0, but probably 2 ticks over that. I use the notification bar swipe to turn it up or down, so I don't know exactly, I just set it to as dim as I'm comfortable with in any situation. Power mode and auto-brightness are turned off.
I switched my background from the default to one that's very dark. I'm convinced that makes a big difference.
I do use a task killer, but I leave my email running, along with whatever else seems like it should be kept running.
Obviously when you look at percentages, there's always going to be *something* at the top of the list, so it's pointless to constantly try to knock whatever's #1 down to the bottom. Different people use their phones differently, so if someone else has their display at the top, it just means they're looking at it a lot and maybe have it too bright. But no matter what you do, something's always going to have a higher percentage than anything else.

How are you able to control the brightness with the notification swipe? I've made it brighter but not dimmer.
Sent from my SPH-D700
So for all the people that have their phone on the lowest brightness, but get a Display usage >50%...are you using your phone that much?
Because I have my display on auto, and my Display usage is a 32%, and that is still enough for it to be #1 on my battery use list.
First, let me get the immature response out of the way: "What sucks my battery? Your MOM!"
Now that that's out of my system, my battery drain is generally caused by the same things as everyone else: screen and TWS. Although I mitigate TWS by using the airplane mode trick which seems to still work for me.

I dunno, I just do. The way the thing works is a little tricky, it seems like it's absolute rather than relative, meaning if your display is already on the dim side, you need to start with your finger way over to the left to take it down the last few ticks. There's only so dim you can make it - the lowest brightness setting would look like a 4 or 5 year old phone at its brightest. That's true regardless of how you dim it. So you may just have it pretty dim and because of the way the notification bar thing works, when you put your finger in the middle, you're making it brighter without meaning to. But if you slide all the way to the left, it'll be as dim as you can make it.

+1 to this, after I changed this setting my time without signal is about 3% before it was up in the 50's. Good tip right there

3-4 hours of talk time takes up 70% of my use during a 10-16 hour usage. Second would be my screen.
My screen is 79% and cell standby only 7%
My screen is all the way down, even tho with the new update I notice my screen got dimmer than before.

Hello all,
Trying to find some info about some behaviour my Iconia has.
I love my device. Way more capable than my wife's Ipad and all that. There's only one thing that irks me: battery drain while the device is idle.
I also have a B&N Nook 1st gen (for books) and an EVO 4G. I leave and use the Iconia mostly at home, close to the WiFi. I'll take it out for long trips and such, but it stays close. I have it set up so that the WiFi antenna turns off when the screen does. Low brightness on the screen, will only charge the battery when it's low enough to charge, etc. It stills drains close to 6-8% if I leave it alone a couple of hours.
Earlier today I rooted the device and use Bloatware Freeze to freeze some stuff. Eventually I'll get rid of some of the gunk the tablet has installed. I want to figure out how to shorten that gap. It doesn't make a whole lot of sense to me that the tablet left alone consumes 8% of battery charge! I mean, if nothing can be done then so be it, I'll learn to live with it.
For my money I would bet that there is something hidden in the Iconia's OS build that thinks it is a 3G/4G device. Now, I'm wondering what would happen if I were to take the next (logical) step and put another ROM in it. Would this make a difference? If I can make the battery drain stop at 5% or less, that would make this perfect.
Thx!

I leave my device with airplane mode checked, and then re-check wifi (as airplane mode will initially turn off your wifi). I get no strange programs showing up in battery usage now.
Will certainly try...
I'll try this next time I head out. Will leave her in Airplane Mode and will check the battery level when I come back.
I did disable the GPS and all location settings. I do not need it to know where I am, since I have the EVO for that.

Well I'm glad I came across this. I didn't even think about leaving the GPS on and consuming battery. Also, where did you adjust for your wifi to turn off when the screen goes off?
EDIT: Nevermind, I found it.
I am developing an app that uses bluetooth and I noticed that if I leave bt on my tab will go dead in 2 days, if I turn it off it can stay idle for several days before needing a charge. I leave the wifi on all the time.

Wow I don't even have 8% drain with Wifi on all the time. There maybe something else in the mix. Most of my drain is the screen as I set it to auto and in my home it ramps up brightness most of the time. Is it possible you have a rogue app? Have you tested the tablet 'fresh', ie: after a factory reset with 1 google profile set up?

This is interesting, on 3.01 & 3.1 I've had zero drain with screen off w/up to 16 hrs. Settings : Wi-Fi disconnect policy never when plugged in, location & security use wireless networks on & gps on. Airplane mode , always off. I can't understand why you folks are having these problems. Hope we find out. Oh & by the way that's not charging.
Forgot to mention I use Juice Defender.
Update
Well, after much tweaking I think I'm somewhere where I feel comfortable. As a disclaimer I don't take the Iconia with me on my daily commute. Again I take my EVO and my Nook with me. The tablet spends the entire time I'm out in the office at home, unused.
I disabled all screen animations and I'm using the tablet on the lowest brightness setting.
I disabled the GPS and all location-related settings.
I rooted the tablet and am using Bloat Freeze to freeze/disable some of the Acer 'junk'.
I put the table in Airplane mode before heading out.
Last night when I went to bed I didn't use it (I was reading a very good book and I did not use the tablet to watch any of my shows). So I put it in airplane mode after I played with the new Google Music app (Impressive!). I went to bed around 11:00 and woke up at 5:00. In this span of time, battery went down by 1%.
Used it this morning to tweet, check a couple of websites, email. Was @ 71% at 7:00AM. Came back close to 7:00PM. Battery was at 67%. Right now (8:50 EDT) it's at 1d 19h 55m on battery @ 59% charge. Heavy usage of TweetCaster, TuneIn Radio, Browser, Market, &c.
Mind you, it was not used for close to 8-9 hours or more. If I were to take it with me the consumption would be more, but then I would probably use Airplane mode when it was not in use. Besides, I can't use it at work b/c the wireless is not compatible.
I'll keep doing some research, but I'm comfortable. I accept the fact that it will drain regardless, since the OS is up. The previous consumption was too much, and I think I can live within the 2% - 4% consumption rate. If it can go down to 1%, though, that would be even better.
Any other ideas welcome.
beautiful Widgets comes with a widget to disable/enable wifi like we're all used to on our phones.
I loaded prime 9.3 today because I wanted to try a 3.2 rom (for GPS and sd-card reasons). On that rom I noticed the 3g settings were visible until I added the line "ro.carrier=wifi-only" to build prop. I was able to see cell standby show up in batt usage.
Not sure if you guys knew it or not but under battery usage you can click on the graph to see a graphical depiction of what hardware used the battery when. If GPS was active when it shouldn't have been you'll see it there.
Interesting...
Are you suggesting that the 3g apk is active on the 3.1 image? I posted this question to a developer in Market that has an app that kills this on the Iconia. Maybe that's the other 2% - 4% I can kill.
Prime is a 3.2 rom. You could try adding that line and rebooting though.
To the stock 3.1 image? Interesting. Any instructions?
You'll need an app like root explorer that will let you mount the /system partition as read/writeable. In the /system directory there will be a build.prop file that you can open with a text editor (root explorer has this feature built in). You'll see many "ro.xxx" lines. At the end of the first group you'll just need to add the line "ro.carrier=wifi-only" without the quotes. Save and exit the file. Reboot tablet. On reboot, it will read the values in build.prop.
On the prime 3.2 rom, the settings for mobile networks are visible without that line added to build prop. I was actually seeing cell standby in the battery usage list. I never saw that on the stock rom. I use a toggle button for the wifi to quickly turn it on/off from the home screen and that keeps wifi from using any battery while sleeping..
I really doubt that GPS is the culprit in your case. Did you click on the battery usage graph to see what hardware was using the battery during the period of sleep?
Also remember
The % charge that the system reports is not always a very accurate indication of how much charge your system actually has - what matters is up time and how long you can go between charges.
Airplane mode is your friend - no real need to disable animation (has nothing to do with idle charge) - the only thing I do is enable airplane mode when away from charger and not using my tab - some of the drain you are reporting could be due to your system scanning for open hotspots.
Also remember all it takes is one poorly coded app to totally screw your battery over - as you are rooted, quite easy to check for apps that relaunch themselves even after closed, apps that want to phone home every 60 seconds - etc.
Would highly recommend you take a close look at any non-stock apps that you have installed.
My battery is dying from full within a few hours on standby. Looking at battery usage says 91% is from wifi. Is there a way to determine exactly what from wifi is draining my battery so fast during standby?
I'm using Prime 2.03 and Clemsyn ver 22
Set your wifi to "off" when screen blacks out. Also go to the market and get the Auto Airplane Mode app. This app along with the wifi off option when screen blacks out basically made my battery life incredible!!
Or read this thread http://forum.xda-developers.com/showthread.php?t=1287799
To be honest, my TF is almost always on and in standby, not in airplane mode, with wifi on. With little to no use, I've had it last multiple days before fully discharging.
The only thing I've done, and I recommend everyone do, is turn off "Network Notification: Notify me when an open network is available". From what I understand, if you have that on, your wifi card will continuously poll and try and find an open network. I could see how that might be your issue.

Several threads on first page of TF forum discuss this.
Prior to ICS my tf101 would last a good 3-4 days on a fully charged battery with my normal usage during the week. Yesterday I installed ICS went to sleep with just over 50%, it had suffered some heavy usage yesterday, and woke up to a completely flat and switched off tablet this morning. This is very unusual performance for my tab.
When I installed ICS I did a factory reset to clean up my tab so only have a pinch of the apps I had previously installed. One thing I did notice is on the battery tab of system settings the tablet was awake 100% of the time were traditionally it would only have a blue mark were it was in use on the awake line. Battery usage data is unavailable, too, so cant see what is causing tablet not to sleep.
Any suggestions?
I would wait until it settles a bit more, plus wait for a custom rom. It probably has some bug, seeing as it is the first ICS for our device.
I also notice some battery drain last week
on HC and ICS
right now i reverted back to honeycomb
ill update you later
if anything changes to me
MyZine Widget
Got rid of the MyZine widget and my tablet now goes to sleep in standby. I noticed, when browsing the running apps list, that the app kept 'restarting' so it could buggy or at the least was having a problem with my tab.
Prior to ICS my battery drain was crazy, especially if I leave wifi on. Not anymore, it's back to normal consumption like I had before the last HC firmware update.
I had the same problem this morning.
take cpu spy to have a look if the tablet goes into depp sleep.
https://market.android.com/details?...251bGwsMSwxLDEsImNvbS5idmFsb3Nlay5jcHVzcHkiXQ..
i had to reboot and then everything was fine...
I've still got problems with my tab. Returned to it after a few hours non-use and it had shutdown itself. Battery Drain still seems an issue too. I'll install that app and see what it reports.
Check WiFi disconnection policy and if GPS is disbled.
Here I am trying to get answers to exactly the op's problem. Everything went smooth installing ics. Even wiped data.
Woke up this morning to a very dead battery. Went to sleep at 83%. Interestingly, the battery graph show nothing after about 80%. No indication on the graph of total discharge...and no app usage. Just straight from 80 to zero.
I can't determine if it's a hung app or what....I've installed almost nothing. And it looks like the tablet drained while it was OFF!

Sorry for the link....I could not get the damn picture posted for the life of me...despite 45 minutes worth of my time.
i also woke up to a dead battery this morning. it was 50%+ when i left it on standby, wifi & gps switched off. i would have expected minimal drain on HC.

Try this
Go to settings /WiFi /click three dots in upper right corner/Advanced/ uncheck keep wifi on during sleep.
go to recently used apps and close all ( swipe to right)
put tab to sleep for a while
Come back and turn on.
go to settings
battery
tap grey battery level graph to expand
check individual bars to see what was on and off.
Looks liks some apps are keepi9ng WiFi and GPS on and draining battery.
It would be really nice in future update to have a setting like below:
Setting
Sleep setting
On screen off close all apps except ( here you get to choose apps to leave open)
I'm glad I am not the only one with battery drain issues. I thought I was doing something wrong.
Several days ago I charged my dock and tablet fully. I then turned off the tablet, closed the lid and didn't use it for a few days, when I went to run it again it was totally dead. I would have expected it to at least hold something of a charge in a completely off state.
Yesterday I left the tablet and dock on but just turned the screen off and again this morning had a drained dock.
Just seems like no matter how I try to settle on a way I still see more of a drain than I would have expected.

I will have to take a look at that setting myself and see what is up with it.
Yes, it would nice to have a sleep setting button for some helpful settings.
Have there been any firmware updates for the dock itself, or is that not possible?
I'm having the same issue dock was at 80% last night get up this morning and it's at 6%. I set wifi to off during sleep to see if that helps any.

Have to close apps that are keeping stuff on. Look at permissions. More and more are adding "prevent "Function X off during sleep."
As soon as I got the update installed I turned GPS off and set WiFi to never sleep, woke up this morning to only 4% battery drain. The tablet went 12 hours and went from 40% to 36%, i also had apps open...
apps open: engadget, camera, browser, gmail, market and settings..
no battery drain yet, updated yesterday and only 5% drain during the night with apps open
Help!
Same problem here. I noticed high battery drain yesterday and didn't think to leave it plugged in.
This morning, it wouldn't turn back on! I've left it plugged in in case the battery drained too far and will try to turn it on later on.
With HC, the power button was buggy (had to press really hard) and seemed that that went away with ICS (well except for now). Don't know if this is related.
Same issues with me. Except my tablet won't wake up when I push the power button. I have to hold and reset it. Here is the kicker: I will get a 20% power drain over 9 hours on top of it. So not only does my tablet not turn on after it being asleep, but I get a power drain as well!
My Settings: Stock ICS off a completely reformatted device, Keep Wi-Fi on only when plugged in, screen timeout is 1 minute and MobileDock Battery Saving mode is on. My battery usage indicator does not work... I have to get the very basic info from my battery widget.
Very disappointed! This was the one thing I wanted fixed the most. I hated using the airplane mode app. It severely affected performance.

Maybe we are all having the random reboot problem.
It makes sense if you think about it.. Mine would randomly go into reboot in sleep and the device would get stuck on the Asus loading screen. So when the device cycle through the loading screen for an entire night, you would find a dead tablet by the morning.
So far, I have encountered 2 random reboots, the only way to bring the device out of the boot screen is to hard reset it by holding down the power button.

balor you most likely got better battery due to custom rom
custom roms tweaked the battery for couple days use.. asus claimed like 9 hours on the tablet.. and like 19 with dock keyboard. custom ics roms inc
