Hi

I am seeing this strange behaviour where my MacBook 2015 shuts off with 75% battery remaining. I have tried resetting the SMC three times but to no avail. I must admit I haven’t been able to drain down the battery as it shuts off after 75% and I can’t check the status without connecting to ac source again. The coconut battery status shows a discrepancy of nearly 5% between the OS status and the reading on the coconut app. Also it shows a design capacity of 44% does it mean the battery is in poor health?
