Solana's second-gen phone surprise: super long battery life. Performance is pretty average, but maybe that's because it doesn't have all those pre-installed apps from domestic Android brands draining power in the background, so battery life ends up being a plus. Full eSIM functionality is included too, so no need to swap SIM cards when you're out. Basically, the phone is almost free—the value of the tokens and airdrops that come with the phone covers its cost. As a backup Android device, it's actually pretty sweet. Clean system + long battery life + eSIM + freebies—nothing to complain about for a backup phone.
