AUX, MicroSD, smaller format and big battery was the reason I went for my Sony Xperia 10 IV (budget phone, got mine new for 260€) device.
Sadly their software updates are only for two years as otherwise I would’ve been interested in the Sony Xperia 5 series (compact flagship). I’m not paying flagship prices for a phone that stops updating after two years.
I hope that the EU regulation forcing 5 years of updates for phones and tablets starting June 2025 will allow me a compact flagship phone with aux, big battery and updates for a long time. repair.eu/…/new-eu-rules-smartphones-and-tablets-…
