battery
28000mAh, roughly 2+ days heavy useAt 28000mAh paired with a 1080x2460 6.78-inch LCD, you can expect about 10 to 14 hours of screen-on time per charge, so this phone is built to skip daily charging if you use it moderately.
charging
33W wired, roughly 90min to fullWith 33W charging on a 28000mAh battery, a full charge takes around 90 to 120 minutes from empty, so morning charging before work is realistic but not quick.
performance
Helio G99, handles everyday apps and light gamingThe Mediatek Helio G99 (6nm, octa-core with two 2.2GHz Cortex-A76 cores) is rated for roughly 620,000 AnTuTu points, fine for social media, messaging, and casual 3D games at medium settings, but not for sustained high-end gaming.
display
1080x2460 IPS LCD, 396ppi, readable indoorsThe 6.78-inch 1080x2460 LCD runs at 396 ppi and lacks a nits rating, so it will be legible indoors and in moderate outdoor light but less bright than flagship OLEDs in direct sunlight.
camera
64MP main, 4K video at 30fpsThe 64MP main sensor with PDAF covers everyday shots, while 4K@30fps handles video, but the lack of optical zoom and the smaller sensor mean distant subjects will be soft and low light will need a steady hand.
durability
IP68/IP69, waterproof to 1.2m for 30minIP68/IP69 dust and water resistance rated for submersion up to 1.2m for 30 minutes means you can use it near a pool or in light rain, but not for snorkeling or heavy splashing.
connectivity
LTE, Wi-Fi 5, Bluetooth 5.2, no 5GLTE with Wi-Fi 802.11ac and Bluetooth 5.2 covers reliable 4G data and wireless peripherals in most regions, but no 5G means slower downloads in areas where 5G is the norm.
