Why is the battery on my iPhone 4S suddenly draining so fast?

It used to use a reasonable amount for a smart phone, but starting this week, I can lose 50% of the charge in one day with minimal use.

Close all of your apps when you're finished using them, make the brightness low, turn off ask to join networks, turn off Wi-Fi if not using it. Then you should be good

Do you put your phone on the charger too much? If you do that tends to burn the battery out. That happened to me and I had to get a new battery
