What type of battery is used in smartwatches?

In smartwatches, Lithium ions or silver oxide batteries are used. Lithium-ion batteries are rechargeable types of batteries that are composed of cells.

In a cell, the lithium ions move from the negative electrode to the positive electrode through the electrolyte while discharging.

When plugged in, the lithium ions move from the positive electrode to the negative electrode. Lithium-ion batteries possess a high energy density, which means they can store a large amount of energy compared to other batteries and have no memory effect (the battery is not affected by repetitive charging). 

Can smartwatch batteries be replaced?

As smartwatches contain a lithium-ion battery, and they slowly degrade with time.

As the lithium-ion battery work on the principle of the ion movement between the positive and the negative electrodes.

The discharge/charge cycle elevates the cell’s temperature and causes aging, decreasing the battery’s performance over time.

So you need to replace it after a certain period. The smartwatch batteries are replaceable; you can replace the battery by reaching out to the nearest service center or by yourself by following the guidelines carefully.

How long do smartwatch batteries last?

The Smartwatch battery usually lasts up to 15-24 hours. The time duration varies with the brand. Some smartwatches can last a couple of days, depending on their usage.

These batteries have high energy density; hence are more durable and offer long battery life. The features available on the smartwatch affect the battery life.
