Battery usage won't show

[lpuniverse]

Hello,

I fully charged my iPhone 7 plus and now I see after a whole day of use that my battery usuage wont show how long my iPhone was in standby or usuage. It just shows "-". Is this an software issue? With my battery self is nothing wrong

Same. It's annoying

Mine did this the first charge or two. Now it works perfectly.

Mine started working again after a few days of it or working. I sent in feedback about it.

If you restart your phone after full charge it won't show battery usage

When you plugged it in to charge, was the battery really low or was it at 60-70% or more?
