It may be possible the battery is going bad. What device is it and how old?

Welcome to Android Central! Also, when you see something like that happen, check your Settings>Battery​ screen, and see what apps or services are using the most battery. Look at the graph and see if the device was kept awake all night, which is usually because of some malfunctioning app.
