I am thinking of getting a S7 to replace my S4. I recently started wearing my watch to bed to track sleep but it complicates my charging routine. I am thinking to use my S4 for sleep, and the S7 for daily use. So my S4 would charge all day, and my new S7 would charge all night.
Do you just change watches and the synchronization happens automatically, or do you need to perform some sort of setup? Are there any issues I should be aware of?
