GoSolo Read / what it means4 takeaways

battery

6000mAh, about 1.5 to 2 daysWith moderate use (messaging, social media, calls), you should stretch this past a full day without charging, sometimes to a second day.

display

6.4-inch AMOLED, 403 ppiText and icons look sharp at typical arm's length, and the AMOLED panel delivers dark blacks, though this 2020-era screen will not match the brightness or refresh rate of newer competitors.

performance

Exynos 9611, 2.3 GHz 8-coreThis mid-range chipset handles everyday tasks—browsing, messaging, light games—without stuttering, but demanding titles or heavy multitasking will show slowdowns.

storage

64GB internal, microSD up to 512GBThe 64GB fills quickly once you install apps and media; the microSD slot lets you expand storage cheaply, which was still standard in 2020.
