Down in the lower right corner of the Nextbook screen is a tiny little battery icon that shows you how much battery life is left. It’s hard to see and not very informational. Luckily, there are a number of widgets that allow you to put a battery indicator right on any home screen.
My favorite is the Battery Solo widget from Pedro Maicas that does a great job of showing the percentage left as a number and also as a circular LED style level indicator. It’s free at Google Play.
