Android Studio: what's causing logcat battery

Question

I have an Android smartphone connected to my Mac using a USB cable. When running Android Studio, the following appears in the LOGCAT. These lines continually repeat, sometimes in a slightly different order. It's not clear to me what's causing this and how I can fix it...
