Why does the battery on my galaxy S5 run out immediately.

[AC Question]

This has happened a few times now. My battery will have 75% remaining, I take a photo and the screen goes blank, the battery has drained to zero ??. Just now, with 67% battery remaining, I copied a link from a SMS and again the screen goes blank and the phone has shut down with nothing remaining in the battery. This is becoming annoying and I feel liker throwing the phone in the river.
