Pros

120Hz refresh rate, 5200 mAh battery, stereo speakers, IP64 rating, expandable storage up to 2 TB

Cons

HD+ resolution, basic 8 MP cameras, slow 15W charging, eMMC 5.1 storage, no 5G

Verdict

The Infinix Smart 20 4G is a practical budget phone with a smooth 120Hz display, large 5200 mAh battery and useful extras like stereo speakers, NFC and an IP64 rating. Its Helio G81 Ultimate is suitable for everyday use, but the HD+ panel, basic cameras, eMMC storage and slow 15W charging hold it back. Overall, it offers good value for basic users.
