Should iphone 5 do this?

I will fully charge the iPhone and it will show the plug and 100%. If I use the phone while on charger it'll drop to lightning bolt. Is that normal?

Yup, normal. Even at "100%" there's wiggle room in the charger logic to slow charge the iPhone battery. Same is true with the iPad.

Should it go back to "plug" or stay on lightning bolt? I've never seen this before on any of my devices and just want to make sure I don't have a defective battery. Thanks!
