I heard a lot of users were reporting less:

It really depends what you're doing. I have a cpu meter running all the time and often see electron based apps (spotify, slack, atom) idle on 5-10% cpu usage for no reason. Just having one of those programs will eviscerate your battery life - its impossible to get 10 hours if the CPU isn't asleep most of the time.
That said, in fairness Atom seems to be getting better with each release. But spotify seems to keep getting worse. I've caught it pegging an entire core a couple of times in the last few weeks - just sitting on 100% cpu usage despite having no music playing. I think it was rendering an animated ad in the background or something, despite my paid account. Its really no wonder people don't get 10 hours battery life out of their machines. This shit is the new flash.

Anecdotally a redditor is claiming ~7 hours?
