Device heating

I upgraded my 2 (TWO) contracts in December 2015and selected the Sony Xperia Z5.<br> Heating too much<br> The phone heats up so easily whether it is in my bag or in my hand. <br> It sometimes heats up so much in my hand that I have to place the phone on a cool surface.<br> Battery life poor<br> I find that I most often have to charge my phone twice in the day and it is quite an inconvenience as I rely on my phone for work<br> I really wish I had taken a Samsung phone as people I have spoken to are quite satisfied with the device, support and feedback if there are any complaints<br> <br> #sonyxperiaz5badforyou
