Been running this device for the past 3 weeks.
The last two devices I was using were Nexus 5 and then Sony Xperia Z3.
There is no way to describe how this phone is working. It tops all my previous devices by a mile!
My phone is my mobile office on the go, so if you are looking for a gaming machine I wouldn’t know. But, as for hard core office, taking picture, travelling use etc. this is one of the best!
Battery life: GREAT. The sony was very good but this is even better.
