GoSolo Read / what it means7 takeaways
battery
20000mAh, roughly 2 to 3 daysAt 20,000mAh capacity and typical mixed use, you should stretch this to two full days or three if you are light on video; the large battery is the main reason this phone weighs 640g.
charging
55W wired, roughly 45 to 60 minutesThe 55W charger will top up the 20,000mAh pack in around 45 to 60 minutes from empty, though you will want to budget longer if ambient temperature is cool.
display
120Hz IPS LCD, 700 nits peakThe 120Hz refresh keeps scrolling smooth, and 700 nits is bright enough for outdoor reading in direct sunlight, though not as punishing as high-end AMOLED screens.
performance
Mediatek Dimensity 7050, midrange gamingThis 6nm chipset with Mali-G68 GPU handles everyday apps and light to mid-tier mobile games (think racing sims, MMOs on low-to-medium settings) without lag, not flagship-grade 3D titles.
camera
64MP main, 20MP night vision sensorThe 64MP f/1.8 primary shoots sharp daylight photos and video up to 4K@30fps; the dedicated 20MP night vision module with infrared lights is built for low-light or surveillance use, a rare feature for this price.
durability
IP68, IP69K, MIL-STD-810H ratedIP68/IP69K means dust-proof and waterproof down to 2 meters for 30 minutes, plus resistance to high-pressure water jets; MIL-STD-810H adds shock and drop tolerance up to 10mm, typical for rugged work phones.
connectivity
5G SA/NSA, dual SIM, Wi-Fi 6Supports both 5G standalone and non-standalone modes across bands 1, 3, 5, 7, 8, 20, 28, 38, 40, 41, 77, 78, dual Nano-SIM, Wi-Fi 6, and FM radio, so you can work in most global regions and use two phone numbers.
