Use this guide to replace a worn-out or dead battery in your Galaxy Watch4.

If your battery is swollen, take appropriate precautions. For your safety, discharge your battery below 25% before disassembling Galaxy Watch4. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

Abschluss

If possible, turn on your device and test your repair before installing new adhesive and resealing.

Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the device at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.

To reassemble your device, follow these instructions in reverse order.

For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.

Take your e-waste to an R2 or e-Stewards certified recycler.

Will this same battery work for the 42mm Galaxy Watch 4 Classic? Or will I need to keep searching for a replacement for that model?
