Введение

Use this guide to replace a worn-out or dead battery in your Samsung Galaxy Watch Active2.

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

You might need replacement adhesive to reattach the battery when reassembling the device.

Заключение

Secure the new battery with pre-cut adhesive or double-sided adhesive tape. 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 1 more hour. 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.

Hi. How can I distinguish between battery rather than motherboard disfunción? My watch doesn't charge anymore. It appears to start charging but doesn't.

Dan Frank - Ответить

It doesn't appear swollen either. Took to the beach and swam on salty water and pool… didn't work after.

Dan Frank -

This is the SAME thing that is happening to me. Went to the beach, on the drive home it died, hasn’t charged since. I set it on the charger and it will say 0%, but never charge enough to power on. I took to best buy and they said I need to buy a new watch :(. Would also like to know if you think it is the battery or if the beach water could have fried the whole thing. I wouldn’t think it would since it occasionally will flash the 0% when try to charge it.

Branddy Hopkins - Ответить

Exact same thing in two separate cases. That's it. 0% flashing sometimes and completely dead. And as it seems nobody but us is posting our sad stories. We need to look further and find something on YouTube or online… there must be something…

Dan Frank -

I have been looking online and it seems that the battery has lower charge than what is chargeable. And by going deeper it also seems that there is a way to recharge that same battery at least to the point we're it might start again.
