GoSolo Read / what it means7 takeaways
performance
Snapdragon 662, Adreno 610 GPUHandles everyday apps, messaging, and video playback smoothly, but struggles with demanding 3D games at high settings.
battery
6000mAh, about 1.5–2 days light useWith light browsing and messaging, you might stretch it past one full day; heavy use (video, gaming) cuts that to a single day.
charging
18W wired, roughly 2–2.5 hours to fullNot fast by modern standards, so plan ahead if you need a full charge before leaving home.
display
6.53 inch, 1080p, 400 nits peakReadable indoors and in soft light, but 400 nits makes bright sunlight struggle; 1080p at 395 ppi stays sharp for text and images.
camera
48MP main, f/1.8, 8MP ultrawideThe 48MP sensor and wide aperture handle daylight and low-light stills reasonably well; the 120° ultrawide is useful for landscape or group shots, but 1080p@30fps video is basic.
storage
128GB or 256GB, UFS 2.1 storageFast enough for everyday file access; 256GB variant leaves room for apps and media without relying on microSD expansion.
durability
Gorilla Glass 3, water-repellent coatingGlass 3 is mid-range protection, so scratches are possible; water-repellent coating handles splashes but not submersion.
