Phones have honestly flat lined. Back in 2011 me and my buddy were heavily into phones upgrading what felt like every few months to try the latest and greatest new features. Nowadays you get a marginally bigger optimized battery, upgraded camera, and a mildly upgraded screen, however you pay significantly more. The only people I know who upgrade on schedule are iPhone users. I’m upgrading every 5-7 years now and my next phones probably gonna be whatever I can get cheap enough
