I've been on a refurbished iPhone Xs Max for more than 5 and a half years, and with the double fact that the battery capacity has turned to under 80%, and my iPhone won't support iOS 26, I consider it's time for a change.
Last year, I was already considering a change, but the announcement of the iPhone 16 line disappointed me, because they presented a big feature (Apple Intelligence) which was announced to be released later after the iPhones were already released (for me as French, we have AI since this April), something kinda ridiculous in my opinion. I considered that at the time, I could wait another year to have a new, more advanced iPhone. I wanted a phone change that makes sense to me, to have something new that brings a huge step-up in my daily life, and I will be really happy to have it with me for some years, like I did with my Xs Max.
So I'm going for the 17 Pro Max this year. It will be as wide as my actual one, so I won't lose my habits on this one, despite the fact that I will have a bigger screen. The triple-lens camera interests me a lot, with all of them having 48 MP. I'm looking forward to enjoying what a great complete camera system on a phone can provide, with the 24 MP front-facing camera as well. Very curious about the new thermal processing as well, the improvements between the 15 Pros and the 16 Pros, plus the rumoured vapour chamber cooling, are something I would be happy to have with me to get better capacities all day, especially outside during summer. And I definitely know I will have great battery life and performance with such a phone, so I'm taking that with great pleasure.
I think now is the right time to upgrade for me. Last year was kinda short, and waiting for another year is too far to project for my side, especially with the first rumours about the upcoming iPhone 18 who aren't very convincing in my opinion (and about the projected foldable, I'm curious about it, but I think I won't buy one before a long time).
