From what I understand, iPhones will downclock themselves when the battery degrades to make a charge last longer and prevent crashes. So your slow phones might have been fixable with a new battery.

Man I'm sad we don't have an /r/roguelikes here. Discussion of the genre has been clobbered by the much more popular roguelites and it was nice to have a forum focused on traditional roguelikes. There's a discord but it's not the same.
Some lesser known ones that I think are quite cool:
Shadow of the Wyrm, open world fantasy with a nice vibe.
Dawn of the Mexica, quite brutal lethal combat with an uncommon setting.
Forays into Norrendrin, traditional dungeon crawler setting with distilled gameplay systems. Brogue-adjacent.
The Ground Gives Way, also a traditional dungeon crawler but with a really interesting fatigue-based equipment system and non lethal combat options. Cool item effects and stuff.
Lost Flame, if dark souls was a roguelike. Quite involved combat where attacks are telegraphed and you can dodge them, use abilities for movement etc. Great atmosphere.
