Used to be yearly. I had the 3G, 3GS, 4, 4S and 5.
For some reason the 5s didn't tempt me and the 6 was too big.
So I had to compromise. Smaller screen = android. Bigger screen and stick with iOS. Tried android. Hated it. Got a 6s. Still think it's too big but besides that I love everything about it.
I always buy my phones outright and circumstances have changed since I got the 5 and I can't afford to update yearly.
When they change again I'll probably go back to yearly but given how well the 5
Performed I'm happy enough to stick with the 6s for 2-3 years.
