GoSolo Read / what it means6 takeaways

display

120Hz AMOLED, 3200 nits peakThe 1080 x 2392 AMOLED screen runs at 120Hz with 3200 nits brightness, so text stays readable in direct sun and scrolling through apps feels smooth.

performance

Snapdragon 6 Gen 3, Adreno 710The octa-core 2.4GHz processor handles everyday tasks and light mobile games at decent settings, but not sustained heavy gaming or demanding apps.

battery

5800 mAh, about 1 day mixed useA 5800 mAh battery with moderate 1080p display power should deliver roughly 16 to 18 hours of mixed use before needing a charge.

charging

45W USB Power Delivery, roughly 50-60 minThe 45W charger gets the 5800 mAh cell from 0 to 100% in around 50 to 60 minutes, so a quick morning top-up is practical.

durability

IP66, water-resistant to 1mIP66 rating means the phone survives splashes and brief submersion to 1 meter, but not full dunks or deep water—fine for rainy days and spills.

connectivity

5G, dual SIM, LTE bands worldwideSupport for FDD and TDD 5G, dual nanoSIM, and broad LTE bands (850, 900, 1800, 2100, 700MHz) covers most regional networks in Asia, Africa, and the Middle East.
