Just got a 560-ish MB update. Using Straight Talk.
It's a security update. To my knowledge it doesn't update anything else.
Mine has always said "rapid charging" when I plug in the charger but I don't have a "charging screen"...Not sure if you are addressing my comment, but I can tell you 100% for certain this charging screen never appeared on my phone before the May update, so it must have included more than just a security update.

Sounds like you have ES File Explorer installed. ES File Explorer had an update around the time of the May Security Update that added a new charging screen on it, that claims to charge the phone faster. I'd recommend uninstalling it; ES File Explorer has been getting more and more shady, and this latest appears to be the worst yet.
