I haven't gone into great detail about measuring the exact times for the battery.
However, I can say this. Remember how Meizu's previous firmwares said their battery time would last 4 hours if you played video? Well, I played around 17 25-minute videos, and the battery hasn't run out yet. The battery bar is on the lowest, but it isn't flashing yet.
17 X 25-minutes / 60 = around 7 hours of playback.
So as you can see, the battery power has gone up, meaning thumbs up
