I have used this phone for 3 months, it have good battery backup last me for whole day in normal usage, camera is also exellent near about pics look like as it is taken from dslr.
Processor is also good which is packed with 2gb ram, no laggs while playing high end game, heart rate sensor works perfectly and ir blaster too, easy to configuration and the main thing it is water resistance which I loves the most, over all it is the good smartphone to buy.!
