Apple Watch is Dead and Won't Charge

Hi

As your Apple Watch has not been used for a long time, the battery may have fallen into a deep discharge state and now be incapable of holding a charge.

Apple advises that, when storing Apple Watch long term, you should store it with a 50% charge and then recharge it to 50% every six months. See under the heading "Store it half-charged when you store it long term":

Batteries - Maximizing Performance - Apple

Follow the instructions here, including contacting Apple Support (mail-in service may be available, if required) or visiting an Apple Authorised Service Provider if necessary:

• Check your battery and charge your Apple Watch - Apple Support
• If your Apple Watch won't charge or it won't turn on - Apple Support

Be sure to use only an Apple or MFi-certified USB power adapter or third-party accessory in conjunction with the Magnetic Charging Cable or Magnetic Charging Dock when charging your Apple Watch.

If you are already doing so, try using another such cable and/or power adapter (including trying an Apple iPad USB Power Adapter first, if you have access to one, and allowing at least 30 minutes before checking the status of your Apple Watch again).

If required, to arrange service, select your country and follow the instructions on the subsequent page:
