Comparing to my other phone the percentage of battery usage my WiFi seems pretty high. WiFi optimisation is on and the phone is almost always connected to WiFi

it depends i will have to look at my phone when my wife gets home with it.
but if you leave WiFi on all the time even when you leave your routers distance and WiFi is trying to find a wireless network a lot then yes i would expect it to be high because it is contently searching for a network. but if you turn it off when you leave your WiFi network then it maybe kinda high.
The screenshot is from today, it has been on constant home WiFi the whole day. Right now when I checked again 22% of battery is left with WiFi usage accumulating to the same 16%.
On my mom's moto g the WiFi usage is always around 5%. Around the same usage.

Not that it seems too bad to me, but some routers cause issues...also some network setups.
Something to do with the router or network polling your phone way too much.
You'd have to research this possibility tho.....that's all I know about it.
Do you have many wakelocks? Is the phone deep sleeping like a baby?
