Coming to the performances
Camera : 4.8/5
Front 8mp and rear 13 mp with only single led flash. The pics from front cam is pretty good than rear. though it is 13mp you lose clarity when u zoom it. But it is good. Pictures in low light is not that great but manageable. Selfies with front are perfect. Each picture captured in day light is around 3 to 4 mb of size. An 8min 1080p hd video which occupied 1.6gb memory so you can imagine how excellent the videos would be. Other than low light pictures there are no other complaints regarding camera.
Processor and ram: 5/5
Ram is 1gb where and it represents 864mb free , it is a 1.2 ghz quard core processor. the operations are pretty good and there are no hanging issues. the performance is pretty good. No hanging while playing heavy games
Battery: 3.8/5
Its a 2600 Li-ion battery which is non removable. the battery backup is pretty good. Mainly there are no heating problems while gaming. Its doesnt gets heated up but you will feel a lil bit warm for a long play that is’nt a problem. Only the problem is it takes 2hrs40min to get fully charged from 0% with given htc 5volts charger of 2 output.
Speakers: 4.5/5
You get two internal stereo speakers on the top and bottom. Htc desire upgraded it with bass sound and the sound is not too loud. pretty much decent and the external speakers are average.
Display: 4.8/5
It is a 5.5 inch display with gorilla glass3 with 267~ ppi , good screen to ratio percentage.The display is awesome while watching 1080p videos and looks awesome on fullscreen too. There is no kind of lag while watching 1080p videos.
THERE WILL BE MARSHMALLOW UPDATE.
