I'm pretty pissed at them (again). Over the last couple of years, we've seen significant gains in battery capacities for the first time in more than a decade — you can now buy “standard” thickness phones for sane amounts of money with 6-7.5 A·h batteries, and I expected to see 8 A·h shortly. Two times the capacity of just a few years ago with the same volume and for the same amount of money.
What does Apple do with these gains? Crap out a new thinner phone, of course. Now other manufacturers will follow suit, just like they did with the 3.5" jack, and we will be back to square one.
Not once do I remember thinking "I would like this phone to be thinner", yet I wish that this thing would have a bigger battery almost daily.
Thanks again, Apple.
