How to charge an Apple Watch correctly

2 min read · 5 steps · Updated 2 October 2026

Short answer

Place the back of the watch on its magnetic charger until it clicks into place and a green lightning bolt appears. Use the cable that came with the watch and a USB power adapter. A full charge takes about one to one and a half hours on recent models.

Apple Watch charges only with a magnetic watch charger. It does not charge on phone wireless pads. Getting the placement and the adapter right avoids slow or failed charging.

Step by step

  1. Plug the charger into a power adapter

    Use a USB-C power adapter in a wall socket. A computer's USB port charges more slowly.

  2. Remove any plastic film

    A new charger and a new watch each have a protective film. Peel both off.

  3. Place the watch on the charger

    The curved back sits on the puck. Magnets pull it into position.

  4. Check for the green bolt

    A green lightning bolt means charging. A red bolt means the battery is low and needs charging. The watch chimes when charging starts, unless it is in Silent mode.

  5. Use fast charging if you have it

    Series 7 and later, SE 3 and every Ultra charge fast with the Apple USB-C magnetic fast charging cable and a USB-C adapter of 18 watts or more. Apple gives about 30 minutes to 80% for Series 10 and later, about 45 minutes for Series 7, 8, 9, SE 3 and Ultra 3 or later, and about an hour for Ultra and Ultra 2.

Good to know

Optimised Battery Charging, under Settings, Battery, Battery Health on the watch, may hold the charge at 80% and finish shortly before you usually take the watch off the charger. Tap the charging circle on the watch and choose Charge to Full Now when you need it.

A slightly warm watch while charging is normal. If it gets hot, take it off the charger and remove any case.

Clean the back of the watch and the charger with a dry cloth if charging is unreliable.

In short: Charger into a wall adapter, watch on the puck, look for the green bolt.
