But, the question is, “Are the smartwatch batteries replaceable?” We have come to notice recently that the majority of the available smartphones nowadays don’t come with replaceable batteries. So, it’s pretty common to wonder if that’s the case with smartwatches.

If you are in the same boat and have been confused about whether or not smartwatch batteries can be replaced, you are in the right place. This article will explore more about the battery swap process, its possibility, and its effectiveness.

Is it Possible to Change Smartwatch Batteries?

Most of the smartwatches that you buy now come with rechargeable batteries, which mean that you can recharge them at your convenience when the device runs out of battery.

However, what happens when the battery stops working altogether? That’s where things get a little complicated. Changing the batteries in your smartwatch comes with a few restrictions.

Firstly, the process of changing the batteries in your smartwatch will depend on the type of smartwatch you have or the brand of smartwatch you use. Now, when it comes to depicting the type of battery you have, there are two categories:

  • One with rechargeable batteries 
  • One with disposable batteries 

Popular smartwatch brands and types like Apple Watch Series 6, Galaxy Watch 3, Fitbit Sense, etc. are the ones that come with rechargeable batteries. There are negligible brands that come with disposable batteries.

What’s great about smartwatches with rechargeable batteries is the fact that they come with prolonged usage for at least 2-3 years. But, with the benefits come a few downsides. One of the biggest issues with rechargeable batteries is that once these stop working, replacing them becomes a headache.

When it comes to disposable battery smartwatches, there are a few worth mentioning. Options like Fitbit Zip, Misfit Flash, etc. are the ones that deserve a mention. Since they come with replaceable batteries, it becomes a lot easier to change the batteries when they suddenly stop working.

But, unlike rechargeable battery smart watches that generally last for 2-3 years, the ones with disposable batteries generally last for 6-8 months, after which you have to consider replacing the batteries.

What Should One Do if the Smartwatch Battery isn’t Charging?

If you suddenly notice issues with the smartwatch battery, witnessing that it’s not charging as it should, there are several ways to mitigate the issue. Now, keep in mind that if any part of the hardware is damaged, you’d have to consult a professional to fix the problem.

  • Check the charging status – Once that is done, the next step is to check whether or not the battery is charging. If the power cycle that you did in the first step fixed the charging issue, you should notice that the smartwatch is charging again. If not, you’d have to check for other issues.
  • If you notice that the above two steps aren’t doing anything to fix the issue, chances are that the battery needs to be changed and you need to proactively fix the issue for good.

What are the Reasons Behind the Smartwatch Battery Drainage?

Now, in most cases, smartwatch batteries are meant to last a minimum of 2-3 years. However, if you start noticing issues early and see that the batteries are draining faster than they should, there could be multiple reasons behind the problem.

  • Navigate to your smartwatch Settings. Under that, go to Bluetooth and Wi-Fi. What you want to do is check if the battery drainage is caused by these two factors. If you notice that is the case, we’d recommend you disable these two features first. If the battery drainage is minimized, you have now spotted the problem.
  • If your smartwatch has excess applications that could be another potential reason why the battery drainage is so fast and excessive. Sometimes, we don’t realize this but syncing way too many apps is a problem that affects the smartwatch’s battery directly. The best fix for this is to delete the app that you normally don’t use.
