Mine is between 6-7 hours. But on average I'll say 6 hrs 30min. I only get more than 7 hours if I drain the battery to less than 5%. But I don't like doing that. I make sure I charge at around 10-12%. I also use dark themes in forum. And my display brightness never goes above 30%. Am mostly indoors both at work and at home and right now we have shorter day light so no need to increase the brightness. Maybe in summer the battery usage might be different if I've to turn up the display.
6 1/2 hours of screen on time at half brightness playing an hour of spades, 25mins of YouTube, 20mins of Facebook. Those who say they get 7+ hours either have the screen on low brightness or are lying
