If your watch isn’t charging, one of the first things to do is check the charging hardware: the cable, charging block, and Apple Watch contact point. To do this, you’ll need to isolate and test certain part individually.
First, you can try to clean the charging contacts, which are located in the back of your Apple Watch. To remove debris or dirt, you can wipe it with a lint-free cloth. For cleaning your smartwatch, Apple recommends using 70% isopropyl alcohol wipes, 75% isopropyl alcohol wipes, or Clorox Disinfecting Wipes.
To check the cable, first do a visual inspection for any cuts or exposed wires. Then, make sure that your charging cable and block are securely connected to an outlet. If it is still not working, try using the cable with a different charging block, outlet, or USB port. After you identify which part of your charging hardware has issues, you can simply replace it. For maximum reliability, stick to official Apple Watch charging blocks and cables.
If your hardware checks out but you still aren’t charging, there may be another issue, such as software.
