Running Inference on Plugged-in Macs Saves Battery
gajesh · x · 2026-07-12
The author discussed with a colleague that in 24/7 operation scenarios like a Darkbloom node, keeping a Mac plugged in actually results in minimal battery degradation.
Once the battery hits the 80% charging limit, the system switches to AC passthrough, meaning it is primarily powered by the external source and the battery remains mostly idle. Based on this, the author concludes that continuously running inference while plugged in might have less impact on battery aging than everyday typical laptop usage.
