I'm just wondering how well it works and if anyone here uses silent alarms to wake themselves up in the morning with their Apple Watch if you charge it mid day... I'm worried about battery life and sleeping with it. Also I read somewhere that the silent alarms don't always work.. I'm thinking about getting one for my wife. In terms of a routine, if she comes home from work and charges her Apple Watch, theoretically she could sleep with it and use the silent alarm to wake yourself up in the morning. I'm assuming by charging it when she comes home she should be able to sleep with it and continue using it at work.
