I changed a lot when it comes to that opinion.
When I started using iPhones, it was small iPhones or nothing. But I quickly went up to the 7 Plus because of battery life. Those 10-11 hours of SOT with light use on iOS 10 were golden.
I then got the Xʀ, which had a full lifespan of almost six years as main, always running iOS 12. 16 hours of light SOT.
I continued with my good battery life but large iPhones with my current 16 Plus running iOS 18. It gives me 27 hours of light SOT.
I’m a light, efficient user. According to the numbers I’ve seen, the Air would give me 19 hours, but it isn’t small. It is thin. Also, it apparently collapses with heavier Cellular use. My 16 Plus drops to 18-20 hours with moderate to heavy Cellular use. Apparently the Air drops to about half with the same usage, a significantly higher loss.
If Apple gave us a Mini with the battery life of the regular 17 that maintained Plus-like efficiency (so, I get 27 hours and 18-20 respectively on the 16 Plus, the “17 Mini” should give me 22 hours and 14-15 hours of Cellular), and a dual camera, I’d find that interesting.
I don’t care about thinness and size anymore though. So I think I’d still buy a larger iPhone, just due to screen size.
This 16 Plus is perfect. Large, efficient, good battery life, a good iOS version (18). I wouldn’t trade it for a 17 even if you offered that deal for free.
I just have no problems carrying or using this 16 Plus, which is significantly larger than my previous phone, the Xʀ on iOS 12.
Sure, when I put my 5c in my pocket, just to try, it makes a world of difference. But trust me, I wouldn’t want that battery life. I’ve been discussing numbers, so I’ll give numbers. The 5c was at 7 hours of light Wi-Fi use and 5 of moderate (NOT heavy Cellular use, so no camera). Untenable for today’s standards. I’d be at 30% by 5 pm or so. If I used the camera significantly it would die in three hours. I really wouldn’t like that. I like to have wall independence, thank you very much.
I have mentioned that my favourite iPhone is my 6s running iOS 10. But I have tested it with a specific camera-heavy, high brightness, cellular usage pattern. After 2.5 hours of SOT, it was below 50%.
My 16 Plus was at 90% remaining with the exact same usage. Like I said, the 6s runs iOS 10, it isn’t updated. And it ran iOS 10 when I tested that. The difference is so high that I can’t overlook it even if using a small iPhone would be more comfortable (and I’m not going into the loss of screen real estate, that’s another topic).
