There's no substitute for having that gigantic battery.
Very true.
I suppose I'll ask around regarding the battery life differences in a few months when people have had time to use these things. But honestly, I'm happy if it lasts from 6am in the morning to 11pm in the evening with heavy Spotify use and maybe 3 or 4 hours of SOT (i.e. internet/instagram browsing) or until the next morning with slightly lighter use. I very rarely go for longer than 24 hours without being able to charge it at all.
