Default [Q] Is my battery life normal ? If it's not, what can I do ?

Hi guys. My battery life is very good when i dont use my phone. And i dont have mm-qcamera-daemon problem. But when i open wifi or play a game (even when i play flappy bird, not joking) battery drains %1 every 3-4 mins ( just wifi is on, i use greenify), and when i play a game battery drains %1 every 2-3 mins. Is this normal ?

I use stock kernel, i'm on ondemand governor, stock rom. I'm rooted.

Thanks guys.
