I have the original Apple Watch and most days I have 30% power when I go to sleep around 11pm. If I use it to track exercise it can be lower. I have only run out of power early twice in the last year and a half I have owned it. Charging it while I'm sleeping is no more difficult than charging my iPhone while I'm sleeping. In fact they sit right next to each other at night. My only complaint about the battery life is that I do have to carry the propriety charger with me even on an overnight trip. I wouldn't go without it though. I find it very useful.
