battery

5000mAh, roughly one day moderate useThe 5000mAh cell with a 1080p LCD screen should yield about 6 to 8 hours of screen-on time, meaning a full day if you're not heavy on video or gaming.

charging

18W wired, roughly 90 to 110 minutes18W charging speed means a full battery takes around 90 to 110 minutes from empty, and 10W wireless charging is slower for casual top-ups.

display

6.8-inch LCD, 395 ppi densityThe IPS LCD at 395 ppi is sharp enough for text and photos at phone distance, but standard brightness for an LCD; you will struggle reading this in direct sunlight.

camera

48MP main, 5MP ultra-wide, 115 degreesThe 48MP f/1.8 primary with PDAF handles well-lit shots and low light reasonably, while the 115-degree ultra-wide captures wide group shots and landscapes without needing to step back.

performance

Dimensity 810, light gaming and multitaskingThe Dimensity 810 (Cortex-A76/A55 hybrid, Mali-G57 GPU) handles everyday apps, video playback, and light 3D games at lower settings; heavier titles or sustained gaming will throttle.

connectivity

5G, dual Nano-SIM, Wi-Fi 5, Bluetooth 5.15G support (Sub-6 bands 2, 5, 25, 41, 66, 71, 77) plus dual SIM gives flexibility for two carriers or personal/work numbers; Wi-Fi 5 and Bluetooth 5.1 are current standard.
