I love lenovo vibe k5 .i have bought this phone 1 years ago.its till performed ver well even today .its battery is 2800 mah .that is once you charged it completely to hundred percent it is very good to carry this phone with a whole day. I like this phone. Its best feature is it has theDOLBY ATMOS features .thats means if you activate dolby atmos your phone is changed into a two speakers phone.so its best facility is its sound quality.nothing less than the video quality .the video quality is too good.afteeall it is the value of money phone.
