Apple just released a new official version of Watch 6.1.3 and in it some important errors detected are corrected. It seems that this update comes from problems with the tool that warns of an unusual heart rate and other small errors.
In addition, Apple also launched a new version of watchOS 5.3.5 for those users who cannot update the iPhone to the iOS 13 version. Undoubtedly these updates arrive unexpectedly and new versions were not expected for all users today, but solving the problems and bugs detected is important and it seems that in this case the update was necessary.
The previous watchOS 5.3.5 update was released approximately four months ago, so we imagine that in this time detected problems have been corrected. In the case of watchOS 6.1.3, everything suggests that the problems detected are important and therefore the update is recommended as soon as possible.
Actually on my Apple Watch Series 4 I do not notice failures beyond a higher battery consumption than usual, but I doubt that it really is an update to solve this. In any case, the new version is now available for download directly from the Watch application of our iPhone, in General> Software update. Remember that you have to have at least 50% charge on the watch and have it connected to charger during update process.
I've been trying to download the update for a while and I can't
After installing it, the battery consumption has skyrocketed.
