You may have enabled Wi-Fi+ so that your phone switches to mobile data if the Wi-Fi network lags.
If you have enabled Wi-Fi+, your phone will simultaneously connect to both Wi-Fi and mobile networks, and switch to the one with better stability. If your phone detects that the Wi-Fi network stutters, it will switch to the mobile network, so that your phone still consumes mobile data even if it is connected to the Wi-Fi network.
To disable Wi-Fi+, go to Settings, search for and access Wi-Fi+, and disable it.
