Do you find playing games slows down your phone?

I have noticed this when I used to play mobile games and ever since I have noticed that playing games slows down my phone or it drains the battery really fast I have stopped playing games on my phone and just use the PC or my console for games.

All the time! Especially if the game is a big file and takes up a lot of room on the phone so I just try to find smaller games so its not too bad.
