Because the battery is probably OLD, OLD, OLD! And we're on the iPhone 5 now the wtf do you expect

Everything was fine for a while and then I tried to text someone back and the touch screen wouldn't respond. So I locked it then unlocked it and it was fine but then it did it again later when I was trying to go through my apps. I again locked and unlocked it and it was fine but this has happen quite a few times now. How can I fix this?
