SuperPower (I got it on AppBrain) is an advanced power management app. It does cool stuff like allow you to schedule your phone to shut off data when the screen is off WHILE scheduling the data to come on for a couple minutes every hour to sync your email AND leave data on if your screen is off but you're downloading something. It didn't seem to play too nice with setcpu but has literally doubled my battery life without a noticeable change in performance. There's a thread on xda about it somewhere, but this is currently an unsupported beta so use at your own risk.

of course it did it shut data off. any app that does that will extend batt life
So basically it is Juice Defender?

sounds like.
Ya, it's a similar concept to JuiceDefender. Less about task management and power profiles, though - isntead of setting up profiles you basically just enable levels of control over your phone for the app. And yes, 94tbird, I am aware that "of course it did it shut data off. any app that does that will extend batt life " but the impressive thing is that it didn't just turn data off, but it managed it so that I didn't notice it was off. If I wanted a phone with no data connection and great battery life, I'm sure I have an old nokia around here somewhere. The point was that it is a smart enough app to turn data off when I don't need it and on when I do, while still keeping my email box synced and all without me noticing a difference (besides the battery life). You could accomplish the same thing with the stock widget to turn your data connection on and off, but you would actually have to turn it on and off. This app does it for you, and seamlessly enough that you don't notice it working. But hey - do as you like. I don't have any connection to the developer(s) of this app, I just dl'd it and it worked really well, thought I would share.
The last couple of days my battery has been draining ridiculously fast. It just went from 50% to 8%, just sitting in my pocket without otherwise being used, in the last 3 hours. Here's what the battery usage displays:
while unplugged for 3h 3m 24s:
Android OS 81%
Cell standby 10%
Phone idle 4%
Display 3%
Android System 2%
Obviously something is going on with Android OS and I suspect something I've installed is doing this. I have Watchdog installed but it hasn't given me any warnings. Is there some way to determine exactly what is causing the battery drain, other than removing apps one by one?
Thanks!
I've suspected that my display keeps coming on when my phone is in my pocket.
Both the power button, and the trackpad turn on the backlight for 15 seconds when pushed, and it's very easy to do both when the phone is in your pocket.
I stopped using the HTC weather app, there is no way to stop it from constantly searching your location and it kills the battery FAST if you are on the move. Since I stopped using it I have seen 10+ hours of battery life a day and I use it hard, internet, gps, music, twitter.
It's the suspend process.
I can't link it to you cause I'm on the phone but if you look around, you'll be able to find it.

I don't think it's the display because the battery usage isn't showing the display as the main battery usage (unless I'm really using it for a long time). It's definitely something belonging to "Android OS". I wish there was a way to determine specifically what process within "android OS" is to blame. I really don't know much about Android or Linux in general so "android OS" is mostly a mystery to me.
I did uninstall several programs yesterday night and was almost convinced it was behaving better but it looks like after the first hour that Android OS is creeping up and overtaking the battery usage and the battery is draining pretty fast despite not using the phone other than to occasionally check the battery usage. At the current rate I'd be lucky if the phone isn't dead before the end of my workday. It probably doesn't help that I have a rather weak signal at work but if it was increased power to the cellular radio that was the culprit, would it show up under "Android OS" or "Cell standby"? I'd suspect the latter, but maybe Android isn't so logical in how it groups processes....
I'll try removing the HTC weather widgets as suggested and look up the sleep process.
Thanks!
It is the "suspend process" like that other poster said. Here is the defect, you can read through if you like. It's a known problem and not only isolated to mt4g
http://code.google.com/p/android/issues/detail?id=11126
How did people determine it's the "suspend" process? I can't seem to find any way to determine what processes are specifically involved. Is there an app that will tell you that? I am running Watchdog Lite set to alert me at 50% cpu and have never got an alert which makes me question whether my issue is the same one described in that thread. Various people were describing 100% cpu activity by the suspend process and it doesn't seem to be the case with me.
I did have 2 weather widgets on my home screen. I deleted both and since then the problem appears to have gone away. I'll have to wait a while to see if it's truly fixed or just a coincidence. Someone in the suspend thread did mention that plugging into a charger temporarily fixed the issue and I did charge the phone for a while after deleting the widgets so I'm not convinced just yet.
One thing I did notice in the battery usage is that google maps seems to have a significant presence, despite the fact that I haven't used maps at all since last unplugging the phone. What is maps doing in the background? I wonder if it's trying to determine my location and cache map data...
Thanks!
Install Watchdog and in its settings, include, monitor, and display all phone processes.

Enable system process and set thrashold to 30% and you will see the suspend process. Or when you notice the drain is happening go to the phone hidden menu. You know the #*#*3626*#*# in the dialer and then from there go to battery usage then select CPU usage, you will see the suspend process on the top or near the top.
Just use some memory management apps. I currently use ES task manager and in advanced settings, i set it to kill all processes when i power down screen. I never use any battery when phone is unplugged(i literally left my phone unplugged overnight midnight to about 7am and it stood at 73% entire time). And having it rooted, i use SetCPU and set the phone at around 768mhz powersave when i'm not messing with the phone heavily. I easily can squeeze about a day and a half out of the battery.

What's the "water" sync? Is that a swype typo for "weather" sync? (Swype errors are annoying in that their usually not so obvious.)
I had also disabled the weather sync (forgot to mention it). Seems to be a lot of little bugs in Sense that need to get fixed.
Why don't you guys do what I did... I have profiles set on setCPU so that when the screen is off the phone runs at 368mhz max and the when the screen is on it'll go up to opp speed... That actually saves alot of battery for me.
Sent from my HTC Glacier using XDA App
Sorry it is weather sync. Yeah keyboard error. I stopped using swype recently for this very reason, but touch input isnt perfect either but still much better for me.
Ya if you are using OC based kernel then use SetCPU to scale your mCPU. Set few profiles for example my max is 1.7ghz, avg is 1.2ghz, min is 768mhz, idle is 368mhz.

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

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.

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.
I have been obessing over my battery stat page and am trying to figure out what exactly "Android System" is. It is usually consuming the highest percentage of battery power. I have tried everything to figure out what action exactly makes Android System get added to the battery stats page. I have disabled everything, every radio, syncing, deleted all widgets. I hardly have any apps as it is. It just seems rather inconsistent because sometimes Ill check the page after making a call and will find that Voice calls has consumed a small percentage of battery and Android System isn't even on the list. Other times I will take it off the charger and make a 30 minute call, but when I check the stats page 70% battery was used by Android System and only 3% was Voice Calls.
Can anyone tell me exactly what triggers Android System so I can make sure I cut down on its battery usage in any way possible

If you asked me I would say all your values are a little screwy. Do you even turn the screen on, on your phone and use it? If you use your phone the Display should be by far the most used. To me it looks like you physically use your phone very little. That is why Phone idle and Android System seem to be the higher numbers.
Guessing you have many accounts syncing in the background. One of the biggies for Android System. So its not that Android System is using so much, the rest of the processes are using so little.
Oddly enough the same thing started happening with my phone recently too.
@Agoattamer
The system wouldn't eat most of the charge in less than 8 hours in normal circumstances. Also about your question concerning accounts, while I'm not seh6183, personally I only have my email account synchronizing and the very same thing happens.
Something is causing the CPU to remain awake, in my case stuck at 800MHz.
The factory reset will most likely solve it, but it'd be best to find the culprit to just try and rectify a specific anomaly rather than reinstalling the whole system.
Has recently any core Google apps been updated? Email, Maps, anything?
I do agree that in 8 hours of non physical use your battery should not be going dead. So I couldn't sleep last night and I did some google searching. Here are some things I found out.
Do you have Googles Goggles installed? Seems it may have a bug where it keeps the camera on even when the phone is supposedly asleep.
Seeing that seh6183 always has his wifi active maybe it has something to do with wifi. I found this from Juri's TechBlog
couple of days ago I finally got the eagerly awaited system upgrade to Gingerbread on my Nexus One. The update went pretty well, although some Nexus One users reported about problems with the updating process. The only thing I noticed is that Dropbox didn't work after the upgrade.
A re-install solved the issue. All-in-all Gingerbread is great. Beside UI enhancements it feels also faster than Froyo. However, after trying it for two days now, I noticed a substantial increase in battery consumption. By looking at the system battery stats (Settings -> About phone -> Battery use), Android System was listed to consume 23% of the battery .
Apparently the problem is a bug in Gingerbread version 2.3.3 (you know there is 2.4 as well) on how the system handles the Wifi adapter. If you go into your Settings -> Wireless & Networks -> Wi-Fi settings, press the menu button and click on "Advanced", you'll see a menu entry "Wi-Fi sleep policy". Gingerbread seems to have a problem when that option is set to "When screen turns off". While that may sound to be the most energy-saving option, the bug turns it into a battery killer. If you switch the option to "Never", the Android system will only consume ~3% in the battery stats.
Obviously, in addition to this, the best battery saver is to just turn Wi-Fi off when you don't need it . Caution, if one of the future updates fixes this problem (which I strongly hope), you have to set the option back again.

Something I didn't see but killed my battery on my windows mobile phone was instant messengers. Do you use any apps that are for instant messaging.
Found this thread also talking about the same bug with wifi
http://code.google.com/p/android/issues/detail?id=15057
So it seems that if you (cmdr001) also are a full time wifi user, you may be affected by the same bug. Check your wifi sleep policy and adjust your settings to "Never".
Install a battery monitor app from the market or spare parts to see what is using your battery. Install Juice Defender to stop all that excessive useage.
Excellent find!!!!!
Just switched the sleep policy to "never" (which ironically I've always used until very recently). Ill return with results after about 5 hours. The only thing is that I'm on android 2.3.5 not 3.3 so we will have to see if the bug was affecting me.
I also don't have Google goggles. And to the above poster, my phone regularly went into deep sleep so it wasn't my CPU that was staying active.
Oh and I've been using watch dog to look for rogue programs for the last 24 hours. I haven't got a single alert.
Sent from my Microwave
I guess the first question should have been what ROM were you using and to try a different one then. Needless to say it still has 2.3.3 components in it. And if you recently changed that setting then my bet is thats the issue. Goodluck.
Watchdog may alert you if you are using too much cpu at one time but I don't think it will let you know what is constantly using the cpu.
Ok there's a glitch somewhere in the battery tracking. I just checked it and android system was consuming 12% battery. I placed one 17 minute phone call and re checked it, I then had 57% android system consumption.
No way.
I'm using a cm7 nightly and I'm about to flash the stable version with a different kernel. Ill do a full wipe as well.

disable sync for accounts
disable GPS
disable wifi gps
disable wifi when not using
set brightness level to auto
set wifi sleep policy to when pluged in
Of course there are a couple more things you could do, and again this is what i do cant say it will work as good for you.

When you use an xperia mini pro like me, with just 970 mAh, you get to try all possible battery savers... and unfortunetly no one of them makes the exception... actually as said evilchild, they don't make difference...
just disable everything that may drain your battery, your launcher effects too can be in cause, get rid of unuseful apps, put your brightness to lowest levels or just get it to auto if your rom use it... choose the best profile for your CPU... and with this you are good for 10 new hours in your daily battery life.
I'm not sure a 'battery-saving' app is real.
They just disable some features that we can manually do that. They just make it automatically disabled.
But, 2x Battery is good. It could disable Wifi or mobile data while the display is off.
one touch battery saver is awesome. create a widget to enable/disable wifi,gps,sync,brightness,bt,data ect with one touch!. free on google play

I found it easier to just go on a sub forum for the phone I had at the time and look up tweaks, tips etc.. I'd say doing this helped me more than any app I found previously, and was easy to do.
Dolphin companion is good and gives more remaining of time.
I use juice defender and the setting: "Only 2G"
3G takes a lot of battery..

None. There are no working saving battery apps, not a single one.
What a battery saving application can do is to change the phone configuration to a lower energy one, just like lowing brightness, disabling data packages and such, to sum up, things you can do by yourself and you'll save the battery that that application consumes.
The best way to save battery is to make a proper use of your phone:
-Disable gps when you don't need it.
-Turn off bluetooth when not needed.
-Keep screen brightness low at all time.
-Disable data packages before going to sleep and enable them again when you wake up.
-Keep your phone clean by periodically uninstalling apps that you don't use anymore and that make unnecesary use of memory, cpu and battery energy.
-Check your battery use statistics and keep an eye on applications that are using energy unefficiently, and replace them with better alternatives. Facebook and facebook messenger are clear examples.
-Some people say that connecting to 2G networks instead of 3G helps as well.
-Activate wifi at home, it seems to eat less battery than connected to 3G.
There are more tips out there, just gogle it and make a responsible use of your phone. Keeping phone clean and lowing brightness will probably make the biggest difference.
Moreover, if android S.O. is on the top of the list of battery use, your phone's software entered a weird condition. Reboot it and if it persist, consider a factory reset.
I hope this helps
I just started evaluating Juice Defender Ultimate to see if it can save battery life, but there are many options that I don't fully understand. I have attached a screenshot of the Notificatin pulldown window from my Galaxy Nexus which shows the JD status. There are 9 objects just to the right of the JD shield. They include 3 icons, 3 colored circles and 3 lines of text. Can anyone explain what each of them mean? I have checked the JD online info, without luck.
My best guess is:
the up/down icon represents mobile data
the red circle next to the up/down icon means mobile data is disabled
the radiation icon represents WiFi
the green circle next to the radiation icon means WiFi is enabled
the 3G icon represents 3g mode
the red circle next to the 3g icon means 3g is disabled and 2g is enabled
As mentioned, these are just my best guesses. I have no idea what the 3 lines of text mean?
