GoSolo Read / what it means6 takeaways

battery

5020mAh, roughly one full dayAt moderate use (mix of calls, messaging, and browsing), you'll get about 24 to 30 hours before needing to plug in; heavier video watching or gaming cuts that to 16 to 20 hours.

charging

18W wired, about 90 minutes fullGoing from flat to 100% takes roughly 80 to 100 minutes with the standard charger, so plan accordingly if you run low during the day.

performance

Helio G80, light gaming onlyThe octa-core Mediatek with Mali-G52 GPU handles everyday apps, social media, and messaging without stutter, but 3D games run at reduced settings or framerates.

display

6.53 inches, 400 nits, no refresh boostThe IPS LCD shows about 83% screen, 400 nits peak brightness is acceptable indoors and decent in partial sunlight, but 60Hz means scrolling and transitions feel standard for a 2020 budget phone.

camera

13MP main, quad setup, 1080p videoThe main 13MP with PDAF captures workable daylight shots; the 8MP ultrawide at 118° fits landscapes and groups, the 5MP macro and 2MP depth add versatility, but all shoot at 1080p@30fps with no stabilization.

durability

Gorilla Glass 3 front, plastic bodyThe screen is scratch-resistant but older generation; the plastic back and frame handle bumps but lack the rigidity of glass or metal, and no water rating means rain and splashes are a risk.
