Battery Menu Bar doesn't show Time Remaining Kinda a unique issue here I haven't been able to find the solution to on Google.  As you can see in the screenshot below, my battery menu doesn't give me time remaining on Battery.  Not even System Preferences gives me it.





Has this happened to anyone else? I'd love to re-enable it.  If it's important, I'm running macOS Sierra.
I can think of several failures to cause that, but let's rule out the obvious.

Open terminal.app and type:

pmset -g pslog


The log will show what the power management subsystem is seeing from the SMC. After trying to connect power, disconnect power and seeing charge for 10 minutes and then off charge for 10 minutes, you should have a good understanding of what is or what isn't working.

At that point, try resetting your SMC one time. Make a note of the information as if that doesn't fix things it's likely a hardware service situation.
