Yes, use it now (Ulitmate) I have found nothing wrong personally. Mine's set for Data on with screen on, Data off screen off.. I don't have a schedule set or anything (i'm always off and on the phone anyway) does increase the battery life a bit.. Download, try it for a bit.. see what you think overall.

I did use it before, just the light version. it was indeed a battery extender. But now I am using ON(X).

Well i have have it on my e4gt and it works great but sometimes it force closes

Nope. IMO, battery saving apps like Juice defender burn more battery than they claim to save.

What does that app do?

Juice defender WILL help. I get about 24hrs to a charge. It simply disables data/location/wifi when not in use and can be customized to run different ways for different apps
-SlimBean...the bulimic's choice for the Galaxy III

Hope this helps. It's fully customizable and it does wonders. U can train it to learn your wifi and after a while, never touch the toggle again. Use it for games so they don't go online and pick up those annoying ads (if your unrooted). And u can schedule when the net comes on to get emails and so forth when your not touching you phone.

Been using Ultimate from the beginning and if set up correctly is the difference between night and day for battery life. It works very well with no problems whatsoever on my end.

+1 When setup properly it can save a lot of juice. Or turn data off when not needed it will save a little more than using JD. But I rather have JD running so things are seamless. For Streaming audio like Spotify I find setting for enable/screen off works the best.

Be honest and tell people you have an extended battery.

i got a small issue with JD ultimate:
i set it quite correctly i think, but then, it prevents datas from coming to my phone, even when they're enabled.
let me explain better:
i set it so datas are off when screen is off and on when screen is on.
so i turn my phone on, datas take smth like 5 to 10 seconds to enable, everything normal till here, then the small H or G appear meaning i'm connected through 3G, but even then, i'm still offline... i wait, and wait 5 mins, but still, the H or G is visible on top right of my screen but.. no data.
i disable juice defender, restart my phone, didn't solve.
then i uninstall it completely, restard my phone, and everything works fine again...
anyone could help me on this one?

Battery life problem

Can anyone tell me what is happening to my phone? Why media used 73% of total battery? Many thanks!
Sent from my GT-N7105 using xda app-developers app

lol, a cliff...
just to see in this pic, it might media keep sync or playing, try recharge it and monitor with BBS

I had the same problem, turned out to be a corrupt MP3 on my SDCard causing the Media Scanner service to go crazy. I used an MP3 fixing program to correct it and it now Media is less than 2%.

What is the program name?

You are maybe also affected by this bug, very, very annoying: https://code.google.com/p/android/issues/detail?id=37199
There is also an app to deactivate the bloody media scanner, but that is also an temporary fix only, because from time to time we need it:
https://play.google.com/store/apps/details?id=com.addz.mediascannerroot&feature=search_result
Personally, I have a shortcut on my home screen to deactivate and another to activate that service... It seems also to be triggered by too many files in a single folder (If I understand the bug report correctly).

Its called MP3Validator (Windows) - http://mp3val.sourceforge.net/

[Q] Sudden Battery Drop

My Galaxy S III had a really big battery drop. Why is Gallery, Chrome, and Polaris Viewer taking up a combined 10-20% of the battery? How do I fix it?
Thanks!
P.S. I am completely stock and unrooted.

Do you leave them on (don't close them after use)?
Try closing them in running apps if you already exit them properly.

I always close all the apps I've finished using it (by holding down the home button), and it seems now that those three are always open.

Like I mentioned, go in settings -> manage application -> running applications and manually stop them.
If they restart on their own, then something is triggering them (most likely a app or setting).

I went into the Settings, and Android is showing that while they are using up battery, they are not running. And also, over the past hour, Android OS is using up 18% and Android system is using up 16%. Aren't they supposed to use up like 4% each?

Do you have bad signal?
Do you use Google Now?

Nope. I have full signal on AT&T and I haven't used Google Now in at least a few days.

Simply being connected to Google Now can be a big battery drain. Definatly something to look into.
Do you have auto sync on? the more things you sync, the more battery drain you get.

OK. And the only app I have enabled to sync is the email client, which only syncs once an hour.

Make sure your media players arent still running in the background and that your network programs arent keeping your phone awake by scanning for new media every few minutes...
When my phone used media excessively, I just went into my media players (allshare, dice player, mx player, UPnPlay, XBMC, etc) and made sure media scans were set accordingly and then shut my phone off and let it charge to full strength.... worked for me

Thanks for the reply. I tried that also. Upnp un installed already. Even took of the battery n reboot couple of times but the DRM Protected thing and media storage still killing my battery
Sent from my SGH-T889 using xda premium

What you ladies and gents are staring at is a wake lock. In this case, due to the MediaScannerService.
There are a few different causes, one being some corrupt image, sound or video file somewhere on your SD card.
Solutions range from killing the service to finding the troublesome files and deleting them.
Good luck,

A few games I play trigger the MediaScanner services to come on and keep the phone awake (wakelock). One being NFS:MW. If you long press the home button after playing it and swipe it away it will kill it.

Currently in training mode, but kind of doubtful of it's usefulness.
I feel like the cost of keeping google location on will offset the savings if not surpass it.

I never have Google location turned on so we will see....... Just the fact that there is a training mode give me some hope plus the app being specifically for snapdragon there may be some code in the app other general battery apps lack.

You need location access enabled for the app to function. I don't know why... Normally I leave it off as well.
EDIT: Also do you freeze apps? I'm trying to figure out which ones are safe to get rid of.

none on this end. update was just released.
Not sure if this makes a difference but i am running houstonn 4.1.2

thanks for that bit of info, haha let me know if it updates again please
I am also on houston's JB build. It hasn't caused considerable battery life loss, but under BBS, it says that
ConsiaBattery (Battery Guru) has caused partial wakelocks a total of 6062 times for 1 hour and 42 minutes.
My phone has been unplugged for 14 hours 43 minutes. That's quite a bit of wakelock if you ask me

I'm getting better battery life, although I do see it using a bit up itself, it does pay for itself, so-to-speak
