Organized around bands, measured signal and latency/packet-loss data, so you can quickly judge how the device performs.
Test process
Signal test
Measures average RSRP, RSRQ and SINR.
Game latency test
While gaming, measures one-hour average, minimum and maximum latency, and packet loss.
Test data is for reference only; network fluctuation is normal, so rely on your actual use. All tests use a cooling fan to rule out uncontrollable factors. See the FAQ for the full test process.
Testing notice:(to avoid misconceptions) 5G / 5G RedCap / 4G device tests cannot be compared across network types
DetailsDrawn to real scale and compared against a 2nd-gen ID card and a 1-yuan coin, so you can quickly get a feel for the device's actual size. PS: you can also compare on the Size Compare page.
The diagram is drawn to real body-size scale for reference, excluding accessories such as chargers, cables, external antennas and stands.
Shows measured RSRP, RSRQ and SINR by carrier.
China Mobile measured signal
Measured signal parameters under the China Mobile network. (averaged)
RSRP
Good-82 dBm
Good antenna performance, fine for daily use.
RSRQ
Excellent-5 dB
Clean quality with little interference.
SINR
Good19 dB
Decent link; speed stays stable more easily.
China Unicom measured signal
Measured signal parameters under the China Unicom network. (averaged)
RSRP
Good-85 dBm
Good antenna performance, fine for daily use.
RSRQ
Excellent-6 dB
Clean quality with little interference.
SINR
Fair12 dB
More prone to jitter at peak times.
One-hour game test data (measured with PingTest)
China Mobile latency & packet loss
One-hour game test data under the China Mobile network (measured with PingTest)
1-hour average latency
Excellent28ms
Snappy response, friendlier for competitive play.
1-hour packet loss rate
Excellent0%
