Best Samsung Gear S3 Battery Replacement - Buying Guide and Reviews 2022

Best Samsung Gear S3 Battery Replacements

Samsung Gear S3 has its place still secured in the Android smartwatch space owing to its top-notch specifications.

It provides one of the longest battery back-ups as compared to its competitors, lasting over 3-4 days of usage in ideal conditions. But the fact that it is powered with a lithium-ion battery makes it harder to deny that it will decay after 18-24 months of usage.

The smartwatch is in no way responsible for this.

Lithium-ion batteries naturally start losing their capacity after 300-500 charge cycles due to its chemical composition. So if you are placing an order of a brand new smartwatch due to battery issues, rethink your decision.

And who wants to let go of an insanely feature-rich smartwatch when we can transform it to new again? On top of it, battery replacement causes a negligible dent in our pocket whereas buying a new smartwatch is expensive.

You can swap your battery for as low as $20 dollars whereas buying a new smartwatch will cost you over $300.

The choice is still yours!

Now, as you have decided to opt for a battery replacement let's walk you through the best Samsung Gear S3 battery replacements.


What to Look for While Buying a Battery Replacement?

A battery replacement must check some boxes to qualify itself as a perfect fit.

Let us look at some of them.


Battery capacity refers to the energy back up a battery provides. S3 is powered with a 380mAh lithium-ion battery. The replacement must match or provide a higher capacity than the original.

If you are all for the always-on display on your Samsung Gear S3 a higher capacity battery is a perfect match. As discussed earlier a battery lasts for 300-500 charge cycles. When you spot a battery with no significant loss in capacity even after 500 charge cycles, you know the drill.


Components manufactured by different companies are not completely identical. Replacements must fit in the original ecosystem of the device. In vague terms, compatibility refers to how well a replacement suits the device.

S3 comes in various models. There does not exist a universal battery to fit all its models. Thus, the battery must offer model-specific compatibility.


Electronics no matter how well built they are, must come with a warranty as they are always prone to defects. The warranty protects you from burning a hole in your pocket if the product turns out to be damaged or faulty.

An ideal warranty is of 18 months and when coupled with a money-back guarantee, it becomes a complete package. You must always read the warranty conditions before purchasing the product to verify the after-sales service.


How will you know if the product claims are true? Customer reviews act as a buffer in this case as they offer an unbiased product experience. It is the best way to know the product without buying it.

You must always check certified buyer reviews to narrow down your choices to the best option available. A rating above 3.5 out of 5 is considered a good deal.
