On iPhones, by default, Wi-Fi continues to work after the device is put into sleep mode, but sometimes it may happen that it can still turn off. If this happens to your iPhone, do the following to ensure Wi-Fi continues to work after the phone goes to sleep:

Go to Settings and then go to General.
Now tap on Reset > Reset Network Settings.
Enter your password and then select Reset Network Settings again.
When it's done, open Settings again and connect to Wi-Fi network.
When your device is connected to Wi-Fi, enable the option Auto-Join.
Now go again to Settings > Battery and make sure that the option Low Power Mode is disabled.
Once again enter Settings, tap on Cellular and make sure that Wi-Fi Assist is disabled.
