Battery still lasts 24 hours. It's slower opening apps than it was before (used to be pretty much instant), but that's about the only difference. Main reason I'm upgrading is a crack in the screen that makes some actions awkward because it doesn't react as well to touch in that area - even then, I've had that problem for two years. I think it's done quite well.How is your Series 2 holding up? I have a Series 6 and wondering how many years I can expect from it.
