My iPhone 3GS won't stay on?

So since the weekend my iPhone turns itself off at less than 50% battery, then when I switch it back on again the apple logo appears but it will not go past that before it switches itself off again. The only way I can get it to stay on is if I charge it to 100%
However....... since last night it won't stay fully on even when it is plugged in to the charger in the wall (when I connect the USB to my laptop it is totally unresponsive) it keeps going on and off on its own. It now has 82% battery and will immediately turn off if disconnected from the charger.

Basically I'm wondering if there's anyone out there who can help me?
Or you could read the question properly as I said, it keeps switching on and off even when connected to the charger.
