My J-3 phone after restarting says low better. why?

[Android Central Question]

My J-3 device when I restarted first says IMS stopped working then after that it says "low better " with an "okay " button underneath why is that?

Welcome to Android Central! Is the battery low?

Does it keep giving you the IMS error? If so, see if the problems persist in Safe Mode: https://support.t-mobile.com/docs/DOC-34449
