Why does my iphone 4s turn it self back on when i turn it of?

Mine does that if I shut it off then plug it in to charge it. Other than that, it doesn't. You might want to get it checked out. Do you slide it to confirm you want it off?

My iphone 5 does that too i went to the apple store and they said it does this to save power so. Its ok and they also said the 4s does this too but thats B. S
