java - ANDROID STUDIO- Service not working when device disconnected to power

Question

I have a problem and that is that the service I use in an Android project does not work when I disconnect the device from the power. If it is connected, it does work. I have tried many alternatives and the last thing I tried is this.

I need help... anything that can solve this problem?
