charging apple watch overnight

Can you charge the Apple Watch overnight?

The short answer is yes. Apple itself acknowledges that you can charge the Apple Watch overnight. The device fast charges from 0—80%, but trickle charges between 80—100%. Still unconvinced? The company has included a Nightstand Mode, which turns the charging Apple Watch into a bedside alarm clock but only when connected to its charger.

We should mention that while you can charge the Apple Watch overnight, there are several reasons you might not want to do this. If you use the Apple Watch to monitor your sleep, you’ll want the device on your wrist rather than its charging cradle at night. In this case, it’s best to charge the watch while you shower, binge a TV series, or perform other mundane tasks. Thankfully, Apple has improved the Series 7 model’s charging speed, cutting its time from 0—80% to 45 minutes. This improvement makes overnight charging an option rather than a necessity.

Regardless of how you use your Apple Watch, the battery life will deplete ever so slightly after every charging cycle. Apple defines this charging cycle as every 100% battery capacity discharged. There’s no indication from Apple that charging overnight affects battery health.
