This is exactly where I am. 15, maybe even 10, years ago I was excited by phone releases that had significant upgrades. This is no longer the case. Screen size ratios have maxed out, cameras are far better than anything I need them for, most flagships have (or have the option of) adequate storage.
Gimmicks like the foldable don’t really excite me. I find them interesting, and could see myself owning one in the future if they become commonplace and affordable. But they’re really not that interesting.
Ultimately, I use my phone primarily for messaging, emails, listening to music/podcasts/audiobooks and browsing the internet. Nothing on the Horizon is going to significantly improve those experiences for me.
I previously had a OnePlus 7 Pro and ran that until the Pixel 7 came out, as my battery life had significantly degraded. I don’t see myself upgrading from this phone for several years at least.
The only thing that would change that, as far as I can predict, would be some startling innovation to battery technology that allows me multi-day battery life.
Edit: I would also jump ship onto a Linux based phone if that were to pick up and become a serious contender.
