[fulhamx5]

I turn off the apple watch when I don't use it and at nights. but it takes long time to start again.

How Does Airplane or Power Reserve Mode Impact for power saving? which one is better? ​

thanks

Why do you turn it off?

But to answer your question, Power reserve would be better I believe.

If you can't charge the Watch at night, and you want to save battery for the next day (until you can get to a charger) you're better off turning it off I think.
