My iphone battery life is draining very fast?

I have the Iphone 4 which I got in January. I got it used from apple. It was working fine but about 3 days ago the battery life began to drain faster. For example yesterday it charged all last night and the next morning by 11:00am it's at 68%

I don't have any notifications on beside text messages. My brightness is very low. What could be causing this? Is there anything I can do? Are there secrets to keeping a longer battery life? Best answer is getting 5 stars.

Why won't my iPhone 4 auto connect or auto recognize previously used Wi-Fi? - 1

I just got an iPhone 4 (which I'm loving!), but every time I turn the phone off (lock it down), it seems to disconnect from my home's Wi-Fi. Then, when I open/unlock the phone I have to re-connect to my house's Wi-Fi.

Is this normal? I can't imagine that this is supposed to be the way it is, because my iPod Touch instantly recognizes my home Wi-Fi and other previously used Wi-Fi locations and automatically connects to them when in range. How can I get my iPhone to auto-connect to previously used Wi-Fi?

Also, I have "Ask to Join" turned off.
