After using for more than 30 days I got:
Great battery backup(i am a heavy user).
Great camera quality even in low light. I have used lots of others device but the comparison to its camera quality is pretty good.
Great user interface and user experience.
Performance is pretty good.
5.Good speakers.
6.Amazing screen.
7.Amazing sound through headphones.
8.Great gaming performance.
need not to say best cell phone of d world. its 2gb ram works better than others 4gb.its 1.8ghz processor works better than others 2.3 or 2.5 ghz processor. gaming n graphics awesome n phone never heats up not a bit like samsung n others.coz apple uses best quality things. only 1800 mah battery works full day with all time wifi / 3G same as samsungs note5 and galaxy s7 edge.
other manufacturer should learn only having 4gb ram or 2.5 ghz processor or 5000mah battery doesnot matter. unless everything is perfect. now on wards I will be only n only apple customer
