Guys, close all the background application which is running without your knowledge. Just follow the below instruction:

* Tap the home button twice.
* At the bottom of the screen you’ll see a row app icons. These are the apps that are running. Slide your finger to move forward or backward through the apps. Chances are you’ll have more than the four that first show up.
* Touch one of the app icon’s and hold your finger on it until they all start wiggling. A small red circle will appear at the top left of the icon.
* Tap on the red circle and the app icon will disappear. The app is now no longer running in the background.
* When you’re done shutting things down tap the home button and the apps will stop wiggling.
* Tap the home button again to return to your home screen.
* These steps will work even if you are currently using an app. In other words, you don’t have to be on the home screen to bring up the row of running apps.

And yes, off the push notification which we're not so much. Even you off the notification, you can still always view the updates for the application when you open them

I just tried but not sure whether it's working or not. Gonna give a try and pray it will help on managing good battery life.

No problem at all dude. I'd tried and works fine for me now. The battery can last for 2 days if don't stick too much on game

Yaloh but I think all the phone are the same when it's come to battery. If you play more online and games the battery will drain faster than normal so cant blame too much on battery but perhaps of our usage though.
