Serious heating issue, need help and advice.

I have a Lumia 1020 and it gets very much heats up while using simple apps like WhatsApp and multitasking and battery drainage is too high. On screen time is 3-3:30 hours on full charge.. I'm on latest developer preview 8.1.1. What should I do?

If u can afford a hard reset then try it.
