Battery backup is ok and not like much in lollypop ,
charging time is more when compared to lolly pop ,
in new marshmallow version 21.4.1220.1877 , it fixed QUADROOTER and enabled 4G LTE MODE
again one more update is coming son with reduced size of the os and some system applications may be removed. Camera is very good. And almost it never hangs. I like the phone but there is one problem which is faced by almost every user and that is the bluetooth and wi-fi problem. And also the customer service is not so good.
