Apple Watch and iPhone go to sleep in middle of day.
How do I fix this problem: my watch and iPhone go to sleep in the middle of the day. It just started two days ago. I don’t want to turn off my alarm. How do I fix this very annoying problem?

I'm not sure what you mean by "go to sleep"? What do you have to do to wake them up? In any case, the first (and simplest) thing to try if something isn’t working right is to restart your Apple Watch and its paired iPhone. If necessary (device not responding), try a forced restart. Both methods can be found here:

If that doesn't help, the next steps would be to unpair and pair your watch again and restore from the backup just created. This should result in no loss of data. It deletes all temp and corrupted files and re-indexes the file system.
