  1. Worn or underpowered hardware — 60% of cases involve an inadequate accessory (slow SD card, underpowered charger, cheap cable).
  2. Software configuration — system update, performance setting, battery-saver mode mis-tuned.
  3. Environment — ambient temperature, Bluetooth interference, dirty USB-C port.

The fix that works (90% of cases)

In most situations where the problem persists after a simple reboot, it's an accessory swap or addition that solves it for good. The product below is the one consistently recommended in Reddit and forum threads when this issue comes up.
