How to Increase Battery Life of Samsung Galaxy S2

i got a new Samsung Galaxy S2 recently. what could i do if i wanna extend the battery life of Samsung Galaxy S2?

I find it bit annoying my S2\'s Battery life is really short !! I charge it in the night and when its 100%, I unplug it and by the morning it goes down to 80% without even using it.

its 12 in the noon and I am just checking it now and its around 25% !!! Really annoying !


I find a online batteries shop, it is ok.

Just because it's called the Samsung "Galaxy" doesn't mean it has to be in this section...

If there was a Samsung Galaxy, the stars should last for billions if not trillions of years. So don't worry.

Just charge the darn thing.....
