display
120Hz AMOLED, 5000-nit peakThe 120Hz refresh and 5000-nit brightness mean smooth scrolling in bright sun and clear text outdoors without squinting.
performance
Snapdragon 7 Gen 3, AnTuTu 864KMid-range chipset handles everyday apps and lighter games (PUBG, Fortnite on medium settings) without lag, but not intensive 3D titles at high settings.
battery
5300 mAh, ~12–13 hours mixed useWith moderate screen-on time and standby, you'll get through a working day without charging; heavy users will need a top-up by evening.
charging
66W wired, ~46 min to fullFrom dead battery to 100% takes roughly 45 minutes with the wired charger; 44% in 15 minutes means you can add meaningful charge in a short break.
camera
200MP main, f/1.9, OISFast aperture and optical stabilization capture sharp, bright photos in dim rooms and hold steady video; 200MP sensor crops well for zoom without losing quality.
durability
IP65/IP66 rating, Mohs 4 glassIP65 (Europe) or IP66 (other regions) handles splashes and water jets; Mohs 4 protection scratches more easily than modern Gorilla Glass, so a screen protector is wise.
connectivity
5G SA/NSA, Wi-Fi 6, Bluetooth 5.45G, dual-band Wi-Fi 6, and Bluetooth 5.4 with aptX HD give fast downloads and solid wireless headphone pairing for music or calls.
