Battery life improvement tip - T-Mobile Samsung Galaxy S II SGH-T989

So I always had an issue with battery life and people probably already know this but underclocking really helps. I under clocked from 1500 down to 1200 and have seen significant improvement. This may not be the best test as I was home all day so I was connected to wifi the whole time but I still think this is pretty good. Running aokp awesome audio 4.2

For me the biggest thing that helped with battery life is open the Maps app, Menu -> Settings -> Location settings, uncheck "Report from this device"

I never did that but i use Rom Toolbox/app manager and freeze Maps (i hardly use it and i noticed it uses alot more battery).
But the best way to conserve the battery is to just turn off the phone and don't use it at all. :

It does work but I cant stand the interface. Why can't FB being the billion dollar company that it is, develop an app that works correctly?
I use the Facebook app and every once in a while I'll see it ducking up my battery and I just force stop it once you re open it seems not to take so much battery

I have the FB app and it didn't drain my battery. I'm still getting 3-4 hrs of screen time. Just set the refresh interval to never in the FB settings and also turn off the messenger location. Turn off notifications that you dont need either. Also, always press the back button when exiting apps, not the home button

Large battery drain

Recently I have been having something, I am not sure what drain lots of battery with leaving no trace that I can see for wakelocking... but it IS keeping my phone awake.
Also I don't even use maps and it eats up a ton of battery wth.
Set your wifi to turn off when your screen is off.
WiFi settings > menu button> advanced> keep wifi on > never
That should help some.
Also, what is your screen on time?

That should work too. The only other way to figure out what is taking all your battery is to scour Better battery stats for rogue wake locks and such. I un installed all my user apps and am reinstalling as I use them so that I don't have a ton of extra stuff running in the background eating all my battery.

I find LTE chews up battery. To turn it off should be settings/more settings/ mobile networks/ network mode. And then choose the one under LTE. Saves lots of battery. Also might want to disabled GPS. I looks like it is on according to pics.

We already get pretty good battery life, up to 2 days with moderate usage... You're not going to get much more out of it...
I wont make t 1 day with my batgery....
Sent from my GT-I9100 using xda app-developers app
I assume you mean battery...
How do you know? What do you do with the device that will use all its power so quickly? Mine is averaging 2 days on a single charge with moderate use; there's no reason why anyone else can't manage that.
Besides, all those so called "battery saver" apps are just placebo's anyway; much like memory saver apps are.
Idk man. I tweet alot. and my 3g sucks battery... 2g isnt an option either....
I know battery savers are fake. I got no such thing like that running.
I think it is because everytime i check what apps are running, some apps are open which i didnt open myself at all...

It doesn't sound like you have any idea what the op is asking about.
Better battery stats is one of the best programs for tracking down what programs are triggering wake locks and bleeding your battery.
Using it i found a few programs which had hidden refresh settings set annoyingly high.

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).

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

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?

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.

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.

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

My phone has been unplugged for 14 hours 43 minutes. That's quite a bit of wakelock if you ask me
