Hope this helps.

Hi,

Bro u have a rooted phone , but you don't have a custom ROM that means that you can not overclock or under clock your mobile, so using cup master or set cpu will not help you.

Solution can be u an flash a new ROM having an overclocked kernel or you can flash a overclocked kernel to your current stock ROM or if you don't want to do any of this simply uninstall cpu manager as it will be eating unnecessary juice from your battery and not helping in any way.

Auto memory manager does improves battery life but only a bit, it basically controls the apps killing rate i.e. it manages how much RAM should remain free at all times helps improves performance of you phone, so don't use an aggressive profile because it will kill apps (background or paused or closed) very frequently which in turn will lead to use of your battery, instead use a mild or less aggressive or default settings this will improve both performance of your phone and use lesser juice as compared to a aggressive setting.

Also keep in mind since u r using Gingerbread so killing apps using task killers after every few minutes will not help , so u can uninstall task killers, also if u need a task killer it is already present in go launcher u can use that.

Juice defender is ultimate app which helps improves battery a lot, but u need to have optimized settings according to your needs.

My advice is use smart profiles by Antutu to create profiles for different timings i.e when you need 3g or wirelss or not as when your are sleeping you don't need wifi or 3g on.

Also best option of saving battery is reducing screen brightness.

You can reduce brightness to 20 % which you are inside the building or working under lights as the screen is properly visible.

And outside in bright sun you can use 35-50% brightness.

Keeping phone at 100% brightness will screw the battery life.

You can use LUX or ambident light senor for automatic brightness setting according to the day light or unnatural light or dark.

hope this helps you.

I forgot to mention point about serious battery saving settings.

1) Use lesser widgets only widgets you really need, as they are battery hogger.

2) Try to reduce push interval for email notification, facebook, twitter, weather widget because using 1-5 min push interval will use a lot of juice, try increasing interval to 30 minutes or more or use manual push if you don't need the notification updates every single minute pooping in. This part eats most amount of battery so if u can change the settings this will improve you battery life a lot.

3) Also watch if any unnecessary services are not running in background, because a lot of apps uses services which eats significant battery , so if there is a application which is not needed at all but is running unnecessary service u can uninstall it if you want, but this is not mandatory.

4) Lastly you can use watchdog app , it log the cpu usage by apps and will let you know which app is eating up a lot of juice. So u can find the culprit and find alternative app for that.
