I have done a decent bit of research on this forum and Google and have yet to discover a solution to this problem.

I have Power Nap disabled for battery power, but my 2016 m5 MacBook is still accessing wifi when the computer is asleep. I have been wondering for months why this machine's battery was dying so quickly when asleep (compared to my other Apple laptops, past and present).

I discovered this while doing some management stuff on the wireless APs at work. I noticed that my MacBook was on the device list with a connection time of xx minutes, even though it had been asleep and in my briefcase since I had arrived this morning. I continued to monitor this, and noticed my machine intermittently disconnecting and reconnecting to the wifi, and all the while it was still sitting in the briefcase.

Any ideas or suggestions would be greatly appreciated.
 
I noticed this MBP behaviour of keeping connected to my WiFi network in sleep mode (when I went to a Sierra MBP 2016 from a Yosemite MBP 2011, that didn't do this), and discussed this with Apple Support then (in chat).

Basically they couldn’t help me at the time, had difficulty to understand what my problem with this behaviour was, and left me only with something of an explanation that his was now ‘standard’ behaviour. I left it at that.

Maybe there is something that can be done about it (e.g. through Terminal). That I don’t know, but what I can tell you is that it has little to do with this or that setting in System Preferences (according to their support).
