After almost a year and a half, your battery is probably just dying. The one in my old Ascend only lasted a year. I would guess a new battery would solve your problem, whether you want to buy two and a charger is up to you.
Whatever you get, make sure it has the same mAh as your stock battery. When I was battery shopping I noticed a lot of the ones for sale online had smaller mAh.
