Here's an app that shows the battery percentage at the status bar (no root required) topic

I installed on my girlfriend's moto G a few months back. It works on Moto Maxx/Droid Turbo aswell.

Install, enable, reboot.

On KitKat the text is always white, meaning you can't see it when the battery is charged. On Lollipop it changes color accordingly.
