Extended Life Battery

Welcome to the forums!
There are many ways to extend the battery life on your phone...
Here are some common things that drain the battery:
Any weak signal will cause battery loss. When a phone/tablet detects a weak signal, it will send more power to the radio to boost its ability to connect to that signal (I think).
Similarly any drop from 4G->3G will cause the phone/tablet to look for a 4G connection, also causing battery drain for sure. The same is true for WiFi -- if the connection gets dropped, the phone/tablet will work a little harder to find it.
Best bet is to use something like Tasker and/or some widgets to really control when any battery draining activity is taking place.
Battery draining activities include:
-The screen being on
-3G/4G
-WiFi
-Bluetooth
-Background data sync
-Any large data transfer or frequent screen redrawing (eg the surfing the web with the browser)
I hope this helps a little... you may also want to have a check in the sub-forum for your device, as other users of the same device are the best to offer help and tips on how to get the most from your phone.
As there are different varients of the SGS II, I am linking all possibilities... go for whichever is the right one for you:
Hope this is of some help!

Hello and welcome to Android Forums! 
You might just be suffering from new phone battery drain. As a new phone, you'll be using it a lot more, thus draining faster.
You might also need to let the phone know what it's capacity is. Modern Li-Ion batteries do not have a memory and do not need to be conditioned, but Android needs to be taught exactly what a full charge represents so that it can manage power appropriately.
One of the things I recommend all new phone owners to do is to perform a deep power cycle.
Let your phone discharge completely, keep it on until you are warned about low battery and then just let it run out. Most phone will shut down automatically around 5%.
Plug the phone into the original a/c charger, not the usb cable. Let it charge to full uninterrupted.
When the phone says full, unplug the phone from the charge and reboot. Once the phone is completely restarted, plug it back into the charger and shut the phone off. Even if it says fully charged, let it charge for at least one more hour.
Unplug the charger and reboot the phone one more time. Now you should start seeing (possibly significantly) longer charge times.
Without a deep power cycle, it doesn't know the true capacity of the battery. Be advised that you should only need to do this once as regularly deep cycling the battery can harm it. Li-Ion batteries perform better and last longer with incremental charges.
