iPhone 7 & Apple Watch 2

[Steve]

There's been much improvements since the 5, the hardware now reduces what is neeeded to run when in standby from what I understand.

Yes it shows the consumption of each app.

Good!

On mine is only:
Usage: X hrs , Y min
Standby: .....
That's all.

Even pressing home-sleep did not fix it.

I am running the iOS 10.1 Beta 3 if I recall from the last update but I think the power consumption details were there before with iOS 10.0

Both phones are on iOS 10, should show the consumption but they don't.
Battery information will be available after using the iPhone for a few minutes.
Seems only a factory reset then an upgrade to iOS 10 would make them show it.
Risky. Even with a good backup little to gain, a lot to lose.
