I bought a MacBook Pro two days ago and when I was using it for the first time I noticed that when it drops below 40% (20%-40%) it shuts down with no warning and it's impossible to turn it back on unless I plug in the power cable. I thought it must be a hardware issue so I got it replaced for a new one. I set up my new computer and I found out that it had the same issue.
I tried resetting the System Management Controller (SMC) as per Apple's instructions at: https://support.apple.com/en-gb/HT201295
Unfortunately, this didn't resolve the issue.
At this point I think it would be stupid to buy a third MacBook Pro just to find out that it's not working again.
Has anyone come across any information that indicates this is a known issue?
For the record, here is my battery information:
