Myth: You Should Disable Bluetooth and Wi-Fi All the Time to Save Battery

On modern devices, leaving Wi-Fi and Bluetooth on isn’t the battery disaster people imagine. iOS manages these connections efficiently. Constantly toggling them can also be more annoying than helpful, because you’ll break features you actually use, like AirDrop, Continuity, Apple Watch connections, and location features that rely on Wi-Fi and Bluetooth signals.

If you’re trying to save battery, you’ll get more impact from Low Power Mode or Adaptive Power than from living like you’re in a constant troubleshooting session.

You can still disable these connections if you want to be more secure when you’re traveling. But if you’re doing it to save battery life, the difference won’t be meaningful enough to make it worth it.
