The way to calibrate an Apple Watch if it has battery problems — 2022

On many occasions we tend to think that a device needs repair because it shows some type of problem apparently caused by its hardware. However, it is not always necessary to go to the technical service and this is the case of some Apple Watch with battery problems, since perhaps it only needs to be reset in a certain way. That is why in this article we tell you how you can calibrate the battery of an Apple Watch.

Hints to calibrate the battery

There are several indications to know that the Apple Watch battery requires a calibration. The first of them is that the battery percentage randomly change, showing strange values ​​like being at 10% and after a while at 20% or similar. Also related to this we find the fact that the device turns off due to lack of battery even though the percentage shown before it was high enough.

Also if you notice that takes a long time to reach 100% charge when it is connected to the power it can be an indicator, although in this case we also recommend that you change the cable and power adapter to rule out that these are the ones that are failing. Also if you notice that battery health has dropped a lot suddenly, something that can be checked in Settings> Battery from the Apple Watch itself.

It is also highly recommended to do a calibration when the battery is new . Not when you just bought the device, but when it has been taken in for repair and the device is still the same, but not the battery. Although the technical service always tries to deliver the watch in the best conditions, a correct calibration is not always achieved.

Is there any risk for calibration?

Absolutely. Performing a frequent battery calibration of the Apple Watch, like any other device, can end up being harmful in the long run because in the end charging cycles are being consumed uselessly, since if it is not required it is not necessary. In any case, stay calm if you think you should calibrate the battery, since it does not expose your watch to risks and physical tools that can damage it are not required.

Apple Watch Calibration Steps

As you will see below, calibrating the Apple Watch battery is not a complicated process, although it is not something quick that is done in a moment. It will take a few hours and you will have to sacrifice the use of the device during that time.

  • Let the clock battery run down completely until it turns itself off.
  • After it's turned off, leave your Apple Watch for about 6 hours without connecting it to power and without trying to turn it on.
  • Connect the watch to its official charger and keep it charging for at least 6 hours continuously. It will not matter if your Apple Watch has charged to 100% long before, since it should not be disconnected or used in all that time.

Once you have done this, the device should already have its battery calibrated and ready to be able to use the clock without any type of problem such as those exposed in the first section of this article.

If this has not solved the problems

If at this point you are still experiencing strange things with your watch battery, unfortunately there is not much more you can do. Perhaps as a last solution you can try to restore it and reconfigure it, if possible, without installing any backup. If despite this the problems are not solved either, we recommend that you go to the technical service to be able to explain the problem and that they verify the exact cause to give you a solution that will probably go through repairing the device. The cost of this will depend on the exact problem you are having, the model of watch you have, whether it is under warranty or whether it is a manufacturing defect. In these last two cases, you may even get a free repair if the failure is not due to misuse on your part.
