MBA shuts down on battery and battery drain

Hello Guys,

I have a MBA 13” Early 2015. It seems that my battery is dying, but I am not sure what is the source of it. A month ago my sister and I compared our battery (she has the same MBA) and then Coconut Battery showed 98% battery life and about 200 cycles. But a few weeks ago I experienced it for the first time that my battery drains quickly, and when it shows about 30% Mac shuts down. After that when I plug in the charger and turn Mac on it shows zero percentage. Few days ago I checked it with Coconut, and it showed 82%. I made a clean MacOS install, did a SMC reset, but the problem is still here. Now Coconut shows 65.1% and it changes after every SMC reset. (for example before I made the reset today I had 64.1%…)

What a !&&* is going on? This computer is about 2 years old, and in a very good condition. I care about and never did any radical thing with it.

Update (10/30/2018)

Here is some new experiences: I usually plug in my iPhone 6s while working on battery. (my phone is a hotspot via USB) If it is not plugged in, the only problem is the draining, but Mac does not goes to sleep earlier then 0-1%. BUT: while iPhone is plugged in it goes to sleep randomly with a low battery percantage. (about 20-30 - never goes down to 0-1%). If I try to turn Mac on, it is unable. After few minutes I can turn it on, and shows almost the same % what I realized before it went to sleep. But: if I plug in the charger immediatelly after the shut down, Mac shows 0%. So this is why I am not sure what is this big mess around my Mac… Please help me!

It seems the behavior of a battery that’s failing. Since you’ve already done all checks on software level there’s not much left other than attempting a battery replacement which sounds the most reasonable and inexpensive thing to do. Despite the little number of cycles, batteries can fail, especially if they’ve been left drained for some time.

Thanks, but I don't really want to buy any aftermarket battery.
