HTC desire826
I'm using htc desire 826 since a year. it's really a good phone if we consider it's feature and processing.
It has very good features that are high quality camera that is13 mp front and rear camera, 2 gb ram, operating system which is upgradable to lollipop and also marshmallow updates will be releasing soon.
It has been given with 2600mah battery but it doesn't last long, phone discharges very fast and the main problem of this phone is it gets heated up due to which battery get low very fast.so I recommend not to take this phone if you want long battery.
