performance

Octa-core 1.6 GHz, 2GB RAMThis Unisoc SC9863A handles routine tasks (messaging, calls, light browsing) but stutters on heavy apps and games; multitasking with more than a few apps open will feel slow.

battery

3000 mAh, about 5 to 6 hours screen timeA modest battery for a 5.45-inch phone means you will need to charge most days, even with light use.

display

5.45 inch IPS LCD, 295 ppiThe 720p resolution and modest pixel density mean text is noticeably soft and colors look flat compared to modern phones, but the screen is dim (brightness not specified) for outdoor reading.

camera

8MP main, 720p video, LED flashStill photos are low-resolution and lack detail for crops or prints; 720p video is soft and suitable only for quick clips to share, not storage.

connectivity

LTE, Wi-Fi 802.11n, Bluetooth 4.2LTE and older Wi-Fi 5 GHz bands are absent, so download speeds max out around 20–40 Mbps on typical LTE, and Wi-Fi range and speed lag behind modern routers.

storage

32GB UFS, microSDXC slot32GB fills fast after the OS; the UFS standard is not specified, but even a 64GB card (rated up to 256GB) will slow write times for media.
