display

120Hz Super AMOLED, 1000 nits HBMThe 120Hz refresh and 1000-nit peak brightness keep scrolling smooth and the screen readable in direct sunlight without constant squinting.

performance

Snapdragon 7 Gen 1, Adreno 644This chipset runs everyday apps, social media, and video streaming without lag; mobile games at medium settings stay fluid, but demanding titles at high settings may stutter.

battery

5000 mAh, roughly 1.5 days light useA full tank of typical messaging, calling, and light browsing gets you through a day; heavy video streaming or gaming cuts that to around 6 to 8 hours of screen time.

charging

45W wired, roughly 50 to 70 minutes fullFrom empty to full takes about an hour, so a quick 20-minute charge before leaving adds a few hours of buffer.

camera

50MP main with OIS, 8MP ultrawideThe main sensor with optical stabilization handles sharp handheld shots in daylight and acceptable low-light video; the 123° ultrawide fits group photos and landscapes without switching lenses.

connectivity

5G SA/NSA, Wi-Fi 6, dual SIM5G connection is available where networks support it; Wi-Fi 6 adds speed on compatible home routers, and two SIM slots let you carry work and personal numbers without a second device.
