Without any noise, without waiting to any beta of iOS and without even is notified with a small note in the center of notifications of our iPhone, Apple just of update them AirPods to the firmware 3.5.1. The update takes place completely in the background without the intervention of the user, and there is no note from Apple stating what are the changes that brings. What if brought, at least in my case, is the obligation of having to reset after upgrading so that they work correctly.
To know if the version of your AirPods is already updated or not go to the menu settings of iOS, and in General > information, at the bottom will be the firmware version of your AirPods which in this case should indicate 3.5.1, provided that are connected to your device as it is evident. In the case that have not updated to this version, you should only you have taken place near the iPhone, open the lid of your box so that they connect and leave a few minutes to see if the update occurs automatically.
After the update I Yes have noticed that my AirPods had more problems for connect is with my iPhone of form automatic, so as not is stopped the reproduction when I took one of them, as itself should occur. Unlink them completely from the iPhone and reset before relink them seems to have been the time solution to that problem. We’ll see if Apple has improved one of the aspects that many users complained: a battery consumption excessive with the AirPods at rest, inside his box, with the result that the whole battery does not last more than 3 days without having even used. Also has been very repeated by users another problem that caused that calls are cut when used the AirPods as hands-free. If had any novelty about what includes this update of firmware of the AirPods you will inform you promptly.
