WiFi AC 5Ghz a killer for battery?

[ajai_dev]

I have been experimenting with the S8 trying to extract the max battery life and after disabling a lot of junk "Bixby included" and taking my phones battery drain over night to a very respectable 2-3% overnight on LTE with AOD off and QHD. The real problem is the drain because of WiFi overnight which in my case is a 5Ghz AC signal from Netgear orbi

The Netgear orbi is configured only for 5Ghz AC and all my devices link to that network. There is no 2.4Ghz used at all neither is b/g/n used so its a static 5Ghz AC connection everywhere.

My S8 which uses 2-3% overnight on LTE with data ON consumes 7-8% overnight with similar configuration but this time with WiFi ON overnight.

That's correct. Many apps want us to update through WiFi and will hold untill you enable it. Otherwise it happens in the background.
I have wifi disabled in standby.
I'm also on 5Ghz btw.

I have disabled auto update for applications since day one.

I have a Netgear R9000 which actually supports AD. My Tab S3 and S8 are connected to it on 5GHz constantly and I see no battery drain.

Not necessarily draining. But wifi enabled in standby tend to use just a bit more. If it really drains a battery overnight something else is going on.

What about over night how much battery percentage do you lose?

I am sure that apps don't update since I have disabled auto update so what else can be happening to get 7-8% drain overnight

Why not use gsam to compare what apps are draining how much with wifi on vs wifi off. then you might at least know if its specific apps that are using the wifi more or whether it is just system using it more. you wont narrow it down any other way.

Of course actually getting gsam to show the app drain is another matter since it STILL keeps randomly losing the ability to split the apps out (about 80% of the time) and then randomly gaining it back again every now and then, and this is after using adb to give it the permissions it needs (it seems to forget it has the permission a lot of the time). I emailed the dev months ago but there hasn't been a single update since.

Thanks for the suggestion using gsam already but I found it very buggy as you have pointed out but over night it says two things have used the most power that being in descending order:

Kernal
Android System

Other than this others have used less than 1-2%

They aren't utilizing ad. Unless you have one of the 2 or 3 ad adapters made, nothing in your house runs on ad
