I paid someone to replace the battery in my Samsung S10E. The battery was never good in that thing to begin with despite all my favorite tech YouTubers saying otherwise. Anywho, I think the repair shop must have gaevin me a bunk battery because it was worse than before. Got a pixel 7 last year. I definitely would have preferred to just be able to swap the battery myself.
Goodness the S9. If I could turn back time and keep that phone. I ended up "upgrading" to an S20 or 21 and hated every second of my interaction with that phone. I ended up "upgrading" again to the fold just so I could have a physical fingerprint sensor instead of the garbage screen one but now have to deal with bad apps and wonky battery life and no cases.
I really think Samsung peaked at the S7 or S9 both were fantastic phones.
