Some users of MacBooks are reporting the issue of their devices shutting down randomly, even though there is still lots of battery life left. This is a pretty common occurrence, and the number of such reports is growing as the days pass.
Apple has acknowledged the problem and confirmed that the random behaviour is manifesting, indeed, on the 2019 13-inch MacBook Pro, even though previous reports prove that this was a real issue on the 13-inch MacBook Pro from 2017, too. This might mean that the bug is more common that Apple wants to admit.
Here is a simple but weird fix:
Users who encountered this problem have to do the following in order to restore their MacBook to working condition:
Keep the MacBook Pro closed and off for a couple hours. Afterwards, proceed with the following steps:
1) Unplug your MacBook Pro from the charging cable and then leave it on while the battery is above 90%.
2) As soon as the battery percentage drops below 90%, plug the MacBook Pro’s charging cable back in.
3) Close all the apps.
4)Close the MacBook Pro (to make it enter sleep mode), and keep it closed and plugged in to charge for more than 8 hours.
5)Turn on the laptop and install the newest operating system update, if one is available.
This seems to be a good solution for many users. Why does it work? We aren’t really sure, all we know is that it does, in fact, work.
However, users who still see the error persisting should contact Apple (or an Apple Store) to fix their device. They’ll know better how to properly fix it.
