I can believe it. My 3GS was solid for three years, and in the last six months the battery would last 12 hours with no use or less than 8 with use. Given this phone is over 4.5 years old and has been charged probably 2000 times and has been in some harsh conditions (but not severely dropped), it has held up well. No phone out there feels perfect, but it's time to compromise on something good enough.
And between loss of the headphone jack and the clear superiority of Plex over iTunes for managing and adding music to my devices, I no longer see a need to stick with Apple. Rather, I see benefits to moving away from their ecosystem.
