Can Bluetooth Preferences keep a Mac awake?
Wednesday, March 15, 2023 - Sam Rowlands
Adrian Mace (https://adrianmace.com/) discovered that his 13" M2 MacBook Pro was suffering from excessive insomnia, where it would continually wake every 6 seconds for 6 seconds. The reason given is "SMC.OutboxNotEmpty smc.70070000 wifibt bluetooth-pcie/" which I believe to be "Bluetooth".
Adrian uses a bunch of Bluetooth devices, but typically if these cause a wake, they cause a full wake, not an Insomnia wake. So Adrian did some research and found an article on "Tom's Guide" for resetting the Bluetooth Preferences https://www.tomsguide.com/how-to/how-to-troubleshoot-and-reset-bluetooth-on-mac.
After which Adrian's Mac has been sleeping a lot better.

Are there any reasons you've found which cause your MacBook to chew through its battery while it's asleep? Or do you know specially why Bluetooth settings can cause this? If so, let me know by using the Contact Us page.
