GoSolo Read / what it means7 takeaways

performance

Dimensity 6300, Mali-G57 GPUHandles everyday apps, light gaming like Candy Crush or Asphalt, and social media without lag, but struggles with heavy 3D games at high settings.

display

6.67" 120Hz LCD, 1000 nits peakSmooth scrolling through feeds and web pages, readable in direct sunlight, though the 264ppi resolution is noticeable if you look closely at text.

battery

5100mAh, roughly 1 full day mixed useAbout 6 to 7 hours of screen-on time if you mix browsing, calls, and messaging; easily lasts until evening if you're moderate on gaming or video.

charging

45W wired, 50% in 30 minutesReaches half charge in half an hour, meaning you can grab 2 to 3 hours of use during a short coffee break if needed.

camera

32MP main, f/1.8 PDAF, 1080p videoCaptures sharp daytime photos and can focus quickly on moving subjects, but caps out at 1080p video (no 4K), and the 2MP depth sensor is a placeholder.

durability

IP54, MIL-STD-810H, Panda glassResists dust and water splashes (not immersion), survives drops and rough handling to military test standards, though the Panda glass is less impact-proof than Gorilla Glass Victus.

connectivity

5G (bands 1, 3, 5, 8, 28, 40, 41, 77, 88), Wi-Fi 6E absentFast mobile data on compatible networks, but no Wi-Fi 6E means standard Wi-Fi speeds around 100–200 Mbps indoors on ac-only routers.
