MBA Mid2012 Battery Health down to 80% @ 184 cycles and 24 weeks usage. Is this normal? Also, when I drain down to less than 5% battery indicator tells me to service battery. Should I be alarmed and have it serviced/have the batteries replaced?
MacBook Air, OS X Mountain Lion (10.8.2)
It's not normal. Unibody Macs batteries are designed to have 80% of their capacity after 1000 charges, so clearly the battery is defective. Take the computer to an Apple Store and, as the Mac is in warranty, a new battery will be free
i think if you want a replacement battery under warranty it needs to be under 80% and under 1000 charges
mine intermittently says service battery since 200 charges and i'm now on 800 charges/81-85% kind of hoping it drops another few % before i hit a thousand lol
Yes, its quite creepy how Apple managed to do this. Creepy and impressive. Although I do wish a problem crops up as soon as it can so I can have it serviced at a more timely manner. To my mixed emotional response it fluctuates between 80-83% now. *sigh*
But 80% before 200 cycles is quite sad. 😟
Fortunately for you, you can get the new battery for free. Also, if the AASP or Apple Store you take the computer has got the battery in stock, you would have the battery replaced the same day you take your MacBook
I'd really love to have the battery replaced, but everytime I come near an Apple representative my MBA behaves better making an unconvincing argument. :|
Glad to know I should be on the look out though. Thanks 🙂
What a strange MacBook you bought. You are welcome
everytime I come near an Apple representative my MBA behaves better
exact image of my macbook lol
Finally caught my MBA being naughty. I wonder if Apple Service Centers will honor this as evidence of a defective battery though?
That's a sign that your battery has a problem, so it should be enough for Apple to replace its battery for free
Just an update:
I have finally sent it in for servicing. As far as the updates I am getting from the technician handling my case, the software tests they are doing are coming up negative. He has asked me permission to reformat my MacBook Air 5,2, which I have given. He suggests that some third party application may be causing the OS X to err in reporting the battery health or cause rapid discharge of my battery.
Although I can attest that when I am using the Air at its full capacity I can drain the battery rapidly (down to 1 hour of discharge time), I have done my tests with all the apps I installed quit (or killed). Since this may be part of the standard operating procedures for testing the MacBook Air, I have so granted permission to reformat (to my dismay). My data are backed up,
At the moment, I am just anxious to get it back. I am more productive on my own machine. I have borrowed a MacMini to do some work on, but its really a different beast. Also, I don't want to end up with my warranty lapsed only to find my battery truly faulty then.
Is this normal: MBA Mid2012 Battery Health down to 80% @ 184 cycles and 24 weeks usage?
