Wifi active with screen off?

Good to hear. Check again later, as certain features I. e. Doze, wouldn't kick in for a while.
 
Power savings kicks in if you aren't using the app - as soon as you use it, it turns on.
Even id the "app" is WiFi.
 
I think the OP is saying he was not using the app on the trouble device during the test. It received a internet via Wi-Fi message while snoozing.
 
Is there any apps or settings that one can check to see if their wifi is active when the screen is turned off? I have a suspicion that my wifi is not being used when in standby. Thanks.
If you go to settings→connection→data use →scroll down to WiFi data usage
