Bluetooth schedule- Sometimes in Extended Mode the underlying Wear OS System Software unintentionally turns on Bluetooth during scheduled off times. This impacts the overall battery savings possible when using Extended Mode and may also result in users being switched into Custom Mode if the Smart Battery Modes app is launched when Bluetooth is scheduled to be off but has been turned on by the system.
Settings change after charging- After auto-switching to Extended Mode, the system does not return to the previous settings. You can manually switch back to Daily Mode if you haven’t changed any settings.
