If I leave USB-powered devices plugged into my MacBook while it’s charging, will it degrade the battery? What I’m trying to figure out is if the USB devices will drain the battery and then the charger recharges the MacBook repeatedly, or do the USB devices consume power directly from the MacBook charger without going through the MacBook’s battery?
My use case is charging my phone or using a high-performance drive in a thunderbolt enclosure. Using these when the MacBook is running on battery, these can significantly drain the battery life. If the MacBook is on the charger, will it mitigate the long-term wear on the MacBook’s battery? Is there anywhere I can find documentation on this?
If this is a potential problem, I think that maybe using a docking station that powers with it’s own cable to AC like a CalDigit. To plug in USB-powered devices there might be a safer way to use them than to use them directly from the MacBook.
