mine was at 90% in late June.what is going on here? i am at 90%.
Are you talking about the Design Capacity % shown in the bottom green bar? That comes from the maximum charge divide by h design capacity. So for example if you had a maximum charge of 6000 and a design capacity of 6300 that would be a 95% "health" (6000/6300=.95).How does Coconut determine battery health percentage? My new rMB, built in 10/26/2015, now with 3 cycles on the battery, went from 99.6% health yesterday to 98.2% today.
Hey, it went from 98.2 to 98.4 to 98.5 as I'm typing this![]()
Yes, and thanks for the explanation how Coconut makes that calculation.Are you talking about the Design Capacity % shown in the bottom green bar?

It is normal for that to fluctuate around a little even when new.
There's no way this can be right...right? From the 2nd to 3rd charge it went down to 94%?
That's 1 day!
That sucks. Well I'm within the return period but I saved over $400 at Best Buy with sales and movers coupons...so did you have to return within the 30 day period? Or did they do it after your 3rd issue for the Lemon policy?I returned my Macbook for this exact issue. No matter which ones, at the store or continuous returns and repurchases, this issue is persistent

It can be that the "Design Capacity" value is just set too high, and that what is now shown as 85-90% is actually the normal capacity which gives you the 9 hours Internet surfing battery usage time. I'd like to know if these laptops become "stable" at 85% or that they drop further and further, which is NOT normal and indeed warrants a return / replacement.I returned 3 computers within the 14 day policy over the summer. So I played around with it for 1.5 months and then i gave up. Apple said it could have been a bad batch, but I think otherwise. I LOVE LOVE LOVE this computer, but I will now wait till 2.0.
gives me more like 6-7 hours of internet surfing time. which minimal brightness and very low cpu speedIt can be that the "Design Capacity" value is just set too high, and that what is now shown as 85-90% is actually the normal capacity which gives you the 9 hours Internet surfing battery usage time.

Did you really test all three over time to see if it were accurate with the performance? Doesn't sound too good.I returned 3 computers within the 14 day policy over the summer.

Sometimes mine shows 82 percent and sometimes 87 percent lol. Its 2.5 year old now
If it's like mine it'll stay just over 80% (mine was at 82%) till the 3 year mark so that Apple won't do **** for you (even with extended AppleCare). Then it'll drop quickly. Went from 82% to 72% in 6mo (under 700 cycles).
Just got my gold MacBook 2 weeks ago. Only 6 cycles so far (I think 3 were out-of-box) and reporting 99% battery life. We'll see how it goes over time.
What's you all's battery manufacturer?
My vendor is 'SMP' and now only 87.6% with 52 cycles.![]()
