Sound quality of iPhone 6s is good for me this song is 85% user-friendly this is my experience I like the style of iPhone 6s the home button very good work many other features in iPhone for sample 3D Touch I most like the feature Siri The backside Apple logo makes the phone special I hate the iPhone 6s battery mAh is very less my opinion the iPhone 6s battery capacity more 2500 Sometime I use the iPhone I am imaging I belong to very rich family the value of iphone is good around 16000-19000
