Phone battery testing?

is it any better way to testing my phone battery level on Facer creator. I can choose the time and watch battery level, but it is very difficult to choose any phone battery level to test if it work or is even hard to set it to 100%

Unfortunately, I don’t think there is one.
The only way it works is by beeing connected to currently displayed time.

Use the Time Machine. If you are using the #PBN# tag, the time machine will change the Phone Battery Level.
