Data Speed

Feb 12, 2019
Hello everybody

i am a bit confused. My Mi Note 3 has an average data speed of 100 Mbps down and 40 Mbps up. With the MI 6X, however only 45 Mbps down and 30 Mbps up. Checked weekly since November 2018 with the apps from and Cnlab. Same SIM card. Same network, same radio cell. same LTE band. Is MIUI the problem? on the Mi Note 3 I have MIUI Global stable on the Mi 6X MIUI Global stable or my Mi 6X?
