Gaming
Light games to heavy 3D, online and offline
- Gaming power: Helio G81 1 of 5, Unisoc T7200 about 1.5 of 5 (estimate).
- Graphics: Mali-G52 MC2 (12 nm) against Mali-G57 MP1 (12 nm).
- Screen: 120 Hz against 90 Hz.
- Light games run well on both. The gap shows in heavy 3D games. How long a phone holds its speed when hot needs testing, so it is not judged.

What we don’t judge on
Security patch level, charging watts, megapixels, benchmark scores and guessed values.
- Security patch level and other software settings change with every update, so one reading can’t judge a phone. We use the maker’s written update promise.
- Charging watts, megapixels, screen size and weight are shown, never scored as better: faster charging doesn’t make a battery last longer, and more megapixels don’t make better photos.
- Chip estimates (1 to 5) come from published design facts: core design and year, graphics, manufacturing and video features. Photo quality and how long a phone holds its speed when hot need testing, so they aren’t judged.
- Values with no source show “not published” and stay out of the verdict.
