GoSolo Read / what it means7 takeaways

battery

6000mAh, roughly 1.5 to 2 days light useAt typical mixed use (social media, messaging, light video), you should stretch this to a full day or slightly beyond; heavy use (gaming, video streaming) will drain it to evening.

charging

15W wired, roughly 2+ hours to fullFrom empty to 100% takes well over an hour, so you'll want to charge overnight rather than top up before leaving the house.

display

6.4" AMOLED, 420 nits peak brightnessSuper AMOLED gives true blacks and sharp colours; 420 nits is usable in bright sunlight but not exceptional, so you may shade the screen in very intense outdoor light.

performance

Exynos 9611, light tasks and older gamesThe chipset handles everyday apps, messaging, and browsing without lag; newer demanding games will run but at reduced frame rates or lower settings.

camera

64MP main, 8MP ultrawide, 5MP macroThe 64MP wide sensor covers standard shots and crops well in daylight; ultrawide captures group photos or landscapes; macro lets you shoot close-ups, but lacks telephoto so distant subjects require stepping closer.

storage

64GB or 128GB, microSD expandableBase storage fills quickly with apps and media; the dedicated microSD slot lets you add a card for photos and video without sacrificing the SIM slots.

connectivity

LTE, Wi-Fi 5, Bluetooth 5.0, FM radioDual-band Wi-Fi and Bluetooth 5.0 cover wireless; LTE reaches most networks but no 5G, and the USB 2.0 port is slower for file transfers than Type-C 3.0.
