Well, not seeing a delay in the icon appearing doesn't necessarily mean the device is constantly connected to WiFi while it's sleeping.
Got a tip for us?

Other WiFi turns off when iPhone goes into sleep mode/is locked

Well, then explain me something. How's that then after changing settings on router that I don't have delay and always I see wifi icon? I'll be at home today for about 4-5 hours, I turned off mobile data, only wifi is enabled. I'll see if this is true or not.
If your device is plugged in and charging it will stay connected.
If not after the screen goes to sleep it will turn off and drop wifi connection.
And reconnect once you wake up the device again.
That's how it works for all iPhones and the way it's designed by Apple.
If you're claiming that yours doesn't drop wifi connection when not charging and after the screen turns off then yours is the only one in the world that behaves that way.
Period.
If your mobile data is off then the WiFi connection will be kept while the device is asleep (similar to a WiFi iPad, for example).
For you all, I make a thread to prove

It's definitely not the only one in the world. I've had an iPhone 6 previously and it didn't drop, and my new SE didn't drop when I first got it last week. This made sense, as it has Wifi Calling enabled. Now it does... even when it's plugged in, disproving the "it's for battery life" argument. I remember when it did do this for battery life in early iPhone models, but I also remember the restriction being removed once more efficient phones came into the picture (around the iPhone 4 or so I think). Definitely by the time Wifi Calling came in.
Edit: Forgot, I have an iPhone 4 on the desk here at work which is on test ready to be eBayed. It's been sat there overnight running off battery. Just clicked the wake switch - yup, wifi is still connected!
Just wondering, those who are seeing it disconnect, do you have Draytek routers? Mine is staying connected at work where we have Unifi and it stayed connected at home when we had an Apple Airport, but it seems to be dropping at home now (we moved to a Draytek router earlier in the week) and in my local (they use a Draytek router).

It’s actually quite simple. WMM APSD (Automatic Power Save Delivery) is a power saving feature featured on some wireless routers. It’s an option that allows the wireless chipset in smaller devices or mobile devices to turn on and off as needed. In theory it should improve battery life seing as your not running two radios. Yes it is true that WiFi saves more power than cellular, but that’s only when data is being transferred (downloading a large file, streaming video etc.) When your iPhone goes into sleep mode large amounts of data (usually) are not being transferred (think of just push notifications mainly) so WiFi turns off and cellular radio kicks in. iPhones in general are more battery efficient than Android counterparts due to the system programming overal. This is why iPhones are touted with the best standby battery life.
Basically Apple knows what it’s doing. If you don’t want your iPhone to keep disconnecting while in sleep mode, go into your router and look for WMM APSD or something similar to power save mode under wireless settings and disable it. Should fix all your problems. ASUS routers tends to come with the option enabled. Also take a look into beamforming. This can sometimes knock off iphones. You may want try disabling those options as well.
Also, Android actually has an option to turn this on and off. I’ve owned every single Nexus, and I do recall under advanced WiFi options there is a (Stay connected to WiFi Always) option that you can change.
