How can you show battery percentage when shutdown and charging?

[AC Question]

I would really love to know whether you can show battery percentage when shutdown and plugged in with a charger.

I have a Samsung Galaxy Tab 3 running android 4.4.2 with an older version of touchwiz. It is not rooted but I am considering to.

Welcome.

I don't know about that specific phone and OS version, but my own Androids show the battery charge level on the display when charging while powered off.
