My most recent phones prior to getting the 6S were the Note 5, iPhone 6 Plus, and iPhone 6. I expected my 6S to be essentially on par with the others, but to my surprise, it's positively superior. I would say it's about 20% better than my 6 Plus, and 30% better than my Note 5 and iPhone 6. Is anyone else getting better-than-expected battery life? Generally when we experience a surprise in the battery life department, it's not a pleasant surprise, so I'm pretty elated to be finishing the day with at least 50% battery remaining almost every single day (and I'm a relatively heavy user). I'm about to head to bed now and am finishing the day with 76% left.
