Having had the 12 mini, 13 mini, and a 13 Pro; I will say two things about the battery life:
- The 13 mini's battery life is unquestionably better. If you have a 12 mini and you're only dissatisfied with the battery life, seriously consider picking up a 13 mini.
- The 13 Pro obviously lasts longer than both. With my light to moderate usage, I don't find the 13 mini's battery (even at 92% health) to be inadequate. Sure, it could always be better. But it's "good enough" and a completely worthwhile tradeoff for a portable and reasonable size and weight.
- I do slap on the MagSafe Battery Pack whenever I'm on vacation and know I'll be out for the entire day just to buy myself some extra time "just in case." But for ordinary daily use when the phone is plugged into my car for CarPlay, can be set on a MagSafe charger while I'm working or at home, and can be charged at night; there's simply no problem with the battery life of the 13 mini. It might not be adequate for everybody, but if you're spending your entire day watching videos or playing games on your phone, a $500 cellular iPad mini is a better value for your money than a $1000+ iPhone 14 Plus or Pro Max.
The minis are the first iPhones since 2016 that I've finally been able to use one-handed again. I honestly don't know how anybody can tolerate the Pro and Pro Max sizes. It's an albatross trying to use it while living life.
Through a carrier promotion, I was able to get a 13 Pro inexpensively. I missed my telephoto lens immensely after upgrading to the 12 mini from the X, and kept thinking in the back of my mind that I might be able to tolerate the 13 Pro's large size and heavy weight to have those features. I do wish the minis had the telephoto lens instead of the ultrawide. But again, tradeoffs.
Having used the 13 Pro for a few months in place of my 13 mini, I was able to make comparisons side by side. Everything I knew I'd love and missed about the Pro-style models was correct: the telephoto lens, the ProMotion display, and the stainless steel body. Every time I'd pick up that mini, the display looked like crap compared to the 13 Pro but it just feels like the right size for comfortable use. It was so much easier to text and type without having to contort my hand in weird ways to reach far-away keys on the keyboard, and even just navigating the Home Screen and dismissing notifications is easier being able to reach most of the screen with my thumb.
After a few months, I ended up switching back to the 13 mini and continue to use it as my primary phone to this day. I occasionally bring the 13 Pro with me as a literal "camera phone" to concerts and on vacation. Not really even for its battery life, but just for that telephoto lens. With the iPhone 15 launch imminently approaching in about 3 months, there's no rumor that the mini will be making a return. I will be holding on to my 13 mini for another year, and hopefully getting enough battery degradation in before AC+ expires to have the battery replaced.
I hope that Apple reconsiders for 2024. I'd even take a 5.6" or 5.8" model as a compromise. But with the 6.1" model getting slightly larger this year, I'm not holding out much hope. Since last year's launch, the smallest current-generation iPhone is 6.1". Yet, I remember when 6.0" phones were called phablets. I had one in 2014 and it was just as cumbersome and obnoxious to use as the current iPhones are.
I just wish Apple would at least continue to offer an option below 6.1" for all of us who need a
mobile phone and not a portable entertainment machine. There are other products from the Nintendo Switch to the iPad that already service that need. Just give us a lightweight, high-quality, reasonably-sized phone for calls, text, camera, and web browsing when out and about.
