GoSolo Read / what it means6 takeaways

display

6.77", 1080p AMOLED, 120HzThe 120Hz refresh rate makes scrolling smooth, but the 1080p resolution on a 6.77-inch screen means text and fine detail are less sharp than higher-resolution phones at this size.

performance

Dimensity 7300, Mali-G615 graphicsThis chipset runs everyday apps, messaging, and video streaming without lag, but struggles with demanding mobile games at high frame rates.

battery

5500mAh, roughly 1.5 days light useWith moderate screen time (reading, messaging, social media), you can expect about 24 to 36 hours between charges, but heavy gaming or streaming cuts that significantly.

charging

90W wired, 50% in 19 minutesYou can top up to half charge in less than 20 minutes, which covers a quick top-up before leaving home, though full charging takes roughly 35 to 45 minutes.

camera

50MP main f/1.8, no optical zoomThe wide aperture handles decent low-light shots and the 50MP sensor captures detail in daylight, but you cannot zoom in on distant subjects without visible quality loss.

durability

IP65, plastic back and frameThe IP65 rating protects against dust and water splashes for about 15 minutes, but plastic construction means the phone is less resistant to drops and scratches than glass-backed phones.
