Editorial report

Oukitel C66 6 GB / 512 GB / Global technical sheet

The Oukitel C66 suits buyers seeking a large everyday phone with dual SIM and broad connectivity, provided they can accept weak performance and low display density. This global version has 4 GB of RAM and 128 GB of storage; storage is expandable, and the phone is also sold in configurations up to 6 GB / 512 GB.

Its 6.73″ IPS LCD display runs at 120 Hz, a typical refresh rate for phones of its time, but its 255 ppi density is among the weakest. Android 16, five years of operating-system updates, Google Services, NFC, USB Type-C, Bluetooth 5.2 and multi-system GPS make the everyday feature set practical. Dual Nano-SIM and a side fingerprint reader add convenience.

The 64 MP rear camera resolution is better than most phones of its time. Performance is among the weakest, though: the Unisoc Tiger T615 (T7250) reaches 308,681 points in AnTuTu v10. The 5,000 mAh battery and 18 W charging are also worse than most, and optical image stabilization is absent. The overall NeoScore is 4.5, placing the phone worse than most phones of its time. It is a functional choice for connectivity and software support, rather than demanding performance.
