Asus zenfone is such best phone under its price name 10000.camera quality is very good and batter than its price range.some heating issu is there.when you play game more than 40 min it over heated and update andriod vesrion 6.0 than perfromence is slow down.and also battry back up is good, but charging is very slow 5000 mph battry 0 to 100 in 2: 40 hr.it is very slow no fast charging is support .that are some bad point.
