Slow, and the battery doesn't last that long.
For a phone that came out recently (summer 2023!) the performance isn't up to scratch at all. Applications that close themselves (to save battery? memory? Ask me first, no...) So you find yourself scrolling through your feed, replying to a message, then starting your application from 0 only to be relaunched at the very top of the feed. It's probably related, but you end up with apps that don't show you any notifications unless you explicitly launch them, and so you miss messages all day until you decide to open whatsapp or telegram.
The photos aren't pretty (but I'm not a photographer, so that's probably a failing on my part too).
As for the battery, if you're like me and you have a lot of metro journeys with a Bluetooth headset, think about getting an external battery, because at the end of the afternoon you're going to be stressing about your remaining 20%.
I'm still giving it 3 stars because changeable parts are something to be encouraged and even congratulated, both economically and ecologically, even if so far I haven't needed to change anything (it's fine, it's not too fragile) and I think that most of the problems are mainly software, not hardware.
