Hey guys

I have a Samsung Galaxy S rooted.

Just wondering as my battery life has shortnened for the past month.

I am currently running SetCPU to control the processor, and have set it at conservative.

I have heard bad things about juice defender and auto app killer etc.

Can you guys recommend a good app to save and to control apps ruuning in the background??

cheers

Juice defender works great for me, i find the more i use the phone heavily the more battery it saves.

Also recalibrating your battery can be helpful, although it doesn't save any battery it can make yor indicator more accurate.

Without juice defender my sgs2 lasted for about 20 hours. With juice defender I have it close to 48 hours. Personally I found that juice defender is the best app to save battery. Easy to customize and flexible

I have heard that setcpu isn't all that reliable with the galaxy s. I read a few threads on xda developers about people having issues with it (I think it messes with the cpu scaling the stock firmware does). Try running it without setcpu for a while and see what happens.

I have used SetCPU with all my android phones, bar my SGS, i dont bother with apps to save the battery anymore, i think its something you have to come to terms with.

My suggestion is look around and see whose got a good rom with good battery.

Im running darkys 10.1 and i charge my phone once every 2 days roughly, and thats with some use on the internet and maybe some emulators.

Do you leave GPS turned on? Try turning that off when you're not using it :)

Try nofrills cpu control instead of setCPU. It is simple and may help, just set max and min speeds you are happy with and try different governors, you may even want to set a slower max speed than full speed to save additional battery if it doesnt impact your day to day usage.
Other than that, use the power control widget to turn off GPS, bluetooth and wifi, or use something like Y5 battery saver to automatically turn wifi on when in a given location and off when not. It works by recognising cell towers, so doesnt take additional battery. Try use apn droid and the widget to disable 3g when not using it as well.
Juice defender can do all these things in one app, especially the paid app, but I just found it tricky to set up so I dont use it.

Also, did you notice the battery life drop after installing a program? may be something is misbehaving and taking up cpu or 3g/wifi time and shortening your battery life.

I've found that SetCPU tends to cause more problems than it's worth.

Tasker scripts are pretty helpful, JuiceDefender seems to work ok .

Install "Where's my droid power" - it gives you a better picture of what apps are using your battery than the built-in battery usage list does.

What modem are you using? You can try flashing a different one, that can sometimes improve battery life. Try BUJP5 if you're using Vodafone or 2degrees, or UGJL2 if you're using Telecom.
