Heat is normal think of device. Much more you using smartphone (games, internet and ect) much more this smartphone heat... If you noticed that your smartphone heat up much more neither before, try to repair it with Xperia Companion, sometime it helping 
Also you wrote that updated your smartphone, but don't now name of software, but you can see number of software, most users knows which number have Nougat, which Marshmallow and ect., so if you post this number users will know which operating system version you have
By the way did you updated with Xperia Companion software or any other application?
