MacBook Pro 13 inches 2017 turn off unexpectedly
My Macbook pro 13 inches turn off before out of battery. I think possibly it because SMC working not normally. I went to ICare and they tell me to replace new batteries and some hardware control about 600 dollars. I have no problem to paying, but I think it can fix before replace and I want to know what is the problem exactly before replace since I am a computer science. I think I will go to Apple store instead of ICare and ask them at Genius bar.
First, my battery health is normal condition.
Second, I think battery progress doesn't work normally. For example, when I charge it more after 100%, the percentage doesn't decrease for 3 hours or more.
The problem seems to if I can reset the percentage of the battery back to the right place, it will be okay.
