GoSolo Read / what it means6 takeaways

battery

6000 mAh, about 1.5 to 2 daysWith typical mixed use (light browsing, messaging, social media), you'll reach a second full day before needing to charge.

charging

25W wired, roughly 60 to 75 minutesA full charge from empty takes over an hour, so plan for a longer sit-down before you leave.

display

6.5-inch AMOLED, 1080x2400, 405 ppiThe Super AMOLED panel delivers sharp text and deep blacks for video or reading, though you're viewing at a standard 60Hz refresh rate (not higher).

performance

Exynos 9611, Mali-G72, casual gamingThis mid-range chip handles everyday tasks and light games, but not demanding titles like PUBG or Genshin Impact at high settings.

camera

64MP main, 12MP ultrawide, 5MP macroThe main sensor captures fine detail in daylight, the 123-degree ultrawide fits group shots or landscapes, and the macro lens handles close-ups, but low-light performance is modest without optical image stabilization.

connectivity

LTE, Wi-Fi 5, Bluetooth 5.0, NFCNo 5G, so you're on 4G networks; Wi-Fi 5 and Bluetooth 5.0 are standard for this class and year (2020).
