Huawei Watch 3 Battery Replacement

Introduction

Use this guide to replace a worn-out or dead battery in your Huawei Watch 3.

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

You may need replacement adhesive to reattach components when reassembling the device.

Conclusion

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. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

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.

Beste Tobias ik heb een watch 3 waarvan de batterij sneller leegloopt, inmiddels werken de sensors niet meer, dus nieuwe batterij besteld met een toolkit, dat de sensors niet meer werken hoop ik dat door dikker wordende defecte batterij de sensorkabeltje is los gaan zitten, dus duim met me mee dat batterijvervanging de oplossing is en dat het horloge dat in augustus 3 jaar wordt weer leven in wordt geblazen, ik durf zekf vervangen wel aan, prijsopgave Eur 329,00 voor Mediamarkt servicecentrum die motherboard gemujk wil vervangen wegens risico uitnemen batterij

You can do it, Peter–I believe in you.

As long as you are careful with the short cables when opening. Those brackets inside have nifty little hooks, look closely at the images and read the text, this way you’ll be safe.

Keep my fingers crossed for you :)
