Question: "Healthy" Macbook Air shutting down after resetting SMC
Hey guys. I have an early 2015 Macbook Air which the battery is currently at cycle 417. Technically, it should be a healthy battery but a few months ago, the battery started shutting down when getting to around 40% and no warnings. I tried resetting the SMC but nothing changed. Also can't calibrate the battery because it never drains the battery completely. A couple of days ago, it's started to get worse and now it shuts down even before and the % goes down almost as quick as the seconds of a clock. The battery says Service Battery. Is there a chance to fix it or only taking to Apple?
Hope you can help. Thank you!
MacBook Air, macOS Sierra (10.12.5)
