M2 Macbook Air Battery Health

[Jai13]

I got the M2 Macbook Air on launch day in August 2022. Battery health is sitting at 90% in with 181 cycles in system report. The health seems really low to me compared to the cycles. I have also always used AlDente or similar 80% battery limiters. What is everyone else's battery health? Attached Coconut Battery history.

My 15" Air is at 96.3% with 37 cycles, and I think it's been charged to 100% 2 times since I got it on whenever release day was.

That seems low to me. But it could also be that I need to charge it to 100% overnight to calibrate it.

Edit: Via coconut battery. Apple reports it as 100%.

My M2 MacBook Air also from August 2022 is currently at a cycle count of 226 with Apple's Battery panel reporting 91% maximum capacity and the actual percentage of (current capacity ÷ design capacity) is at 86.1% (equivalent to what Coconut battery is reporting for health.) So your numbers seem to match mine pretty closely though at less cycles. But my current capacity @ 86.1% design capacity has been holding at 86% +/- 0.5% for many months now. If you have AppleCare+ it really isn't something to worry about and even if you don't you'll still probably get close to 500 cycles before you notice a significant battery decline.

After over a year of ownership, I am at 96% with 37 cycles with my M2 MBA 13". I don't really use my laptop everyday, and often it is plugged into my Apple Studio display so it doesn't go down in charge. Apple and iStat both report the same 96%.

November 2022 purchase. I am at 100% health with exactly 100 cycles used. This is from the stock system information app, so obviously after 100 cycles it cannot be 100% accurately. I do not use Al Dente or coconut battery and like tools. My usage is quite mixed with several days where I am plugged in, and several on battery. I don’t let myself worry about it to be honest, and I just use my stuff for what I bought it for. Battery is replaceable if ever needed, and that is all I care about. With such stellar battery life out the gate, I know that even as the health wanes, I can still muster all day battery life for many years to come.

Same thing here. I am at 97,8 after 12 cycles. I am charging it only to 70% with Energiza. Maybe it has something to do with the calibration...
