The same could be said for a phone though too, if you forget to charge it you are kinda screwed. Most people do have chargers in their car and at work so you wouldn't be as screwed vs a smartwatch. But since the batteries on the smartwatches are small it shouldn't take long to charge.
- If you forget once, you're screwed for the whole day ahead.
- If one day is the average, then that means it will be considerably less with heavy use.
- The total capacity of a lithium battery diminishes over time, and I'm not keen on replacing my accessories as often as the phone itself.
- Having to take it off when you sleep means you can't use sleep monitoring apps.
