Huawei watch3pro turns on flight mode and sleep mode, so does it save power in undisturbed mode?

Huawei watch3pro saves the most electricity by turning on the flight mode.

The flight mode is to cut off the cell phone signal, and all incoming calls and text messages can't be received (you can connect to WIFI to surf the Internet in flight mode). This mode does not consume much power.

Do not disturb mode, when the phone is turned on, it will be muted (no vibration) except for disturbing items, and the status bar will generally have a moon icon, but the alarm clock and countdown will not be muted, and incoming calls and text messages can be received without prompting, and breathing light may blink, which is more power-consuming.

Sleep mode is to set a time period during which there will be no notification sound except notification items. In sleep mode, some background applications, notification screens, flashlights, Bluetooth, and the Internet will be cleaned during sleep. Will be limited, so as to achieve the effect of saving electricity.
