YouTube Channel Tech / Tech An interesting video has been published on NickBrazer, in which he compared the speed of two major smartphones, the Xiaomi Mi 9 and the Redmi K20 Pro. The comparison is interesting is that both models are equipped with the Qualcomm Snapdragon 855 single-chip system and offer 8 GB of RAM in maximum configuration. Before comparing, they installed the same app on the phone, set the same settings, and set the same themes. As the authors of the video have revealed, the Redmi K20 Pro is a little faster than its opponent in the face of the Xiaomi Mi 9, but fingerprints and facial recognition, in fact, occur simultaneously. The speed of launching the app is also not particularly different. What's interesting is when restarting applications, the Redmi K20 Pro model loads them from memory in most cases, while the Xiaomi Mi 9 has already managed to shut down some programs in another test circle.
