I went from a galaxy s5 to s22. About 10 years in diff. The functionality for me is nearly identical. Speed the s22 is much snappier I guess. But not something I care much about. I only replaced it because the touch screen started acting up and security updates were non-existent. I was able to keep the thing going for so long precisely because I could swap out that battery easily. To replace the newer ones involves a heat gun and a suction cup. And as jerryrigeverything says 'glass is glass'.
