I use an iPhone SE2 that I got refurbished in the past 6 months by Apple. I couldn't replace just the battery, because the rear glass had a crack in it. This thing is a mess, refurbishing it feels like a waste of money. It runs out of battery almost daily, has terrible multi-second camera lag when I open the camera app from the lockscreen. Often the phone will just have like a quarter second of UI lag for no obvious reason. The experience is overall very slow and frustrating, an enormous degradation from when I got it as a gift 4 years ago (part of why I'm still using it).

It's a shame, because I like the phone a lot otherwise.
