Sony Xperia M4 Aqua heating up like crazy

I bought Sony Xperia M4 Aqua on Tuesday (03-29) and right from the start it started getting warm and the battery started draining fast. I though it's because the phone is new, it is updating stuff etc. But today M4 is still getting very hot after little usage, like updating apps on stand by. Also the battery issue is left: it went down to 20% after 14 hours of me using it while it should hold 1-2 days. And I didn't do anything special - a bit of Snapchat, Reddit, Facebook, browsing, Twitter....
