MacBook Pro 2018 Battery not correctly working

I have a problem with my MacBook Pro from December 2018. Yesterday the battery was fully charged when I shut it down and when I started it today it had 0 percent left. What could this mean? Is this a software error or is there a problem with the battery? What do you recommend to do?

Thanks in advance!

Solution 1:

I had this problem too, whats your version of MacOs ? If it's not the latest one then update, charge your mac for around 8hrs without using it. It fixed the bug for me, my mac was shutting down at 40% ~ and after those two things he was going low without a problem, hope it can help
