Could be a faulty battery. Could be a faulty phone.
Try and find someone with the same kind of phone as you, and put their battery in your phone. If it works, then you know it's your battery that needs to be replaced. Then try putting your battery in their phone - if it does the same thing with another phone you know for sure.
If your phone does the same thing with a different battery inserted then you know it's an issue with the phone itself and it needs repairs. It could be a shorted circuit.
