Those kind if tests baffle me simply because who watches video for 5-7 hours on their phone .... Yikes I'm happy as long as my phone lasts the day and in recent years 2013-2014 all devices I've had have comfortably seen me through the day so I don't really worry about which is going to give me more in an artificial test as it's not indicative of my real day to day usage ...
