My m2 MacBook air is almost always plugged in, and is set to stop charging at ~80% to save battery. I’ve taken it with me a couple times on the plane in the six months and as you can see it only has 27 charge cycles. That being said, I’ve already lost almost 10% of battery capacity. I’ve compared these numbers to other macs and it doesn’t seem normal to me at all. Also I’m totally unimpressed with the battery life that many people talk about after switching to M processors. I have a feeling that the battery in my old macbook was much more stable and better. What should I do? Can I replace the battery under warranty? Or do I need the capacity to drop even more?
If you take these numbers into account, after 60 charge cycles my battery can be at 80% capacity (but may not, I understand). I read that “a normal battery is designed to retain up to 80% of its original capacity at 1000 complete charge cycles.” And this is very veeeery far from what I see now.
The exact same problem is described in the link, I’m definitely not alone here.
