Is this normal for a 2012 MBA? 10 months, 124 cycles and already at 86% health?
You had 124 charging cycles so far. This number seems to be pretty accurate.
It is perfectly normal if your battery health (maximum capacity) is more or less than 100%, even when brand new, or if it fluctuates up or down over time. The gradual decline is not in a straight line downward, and it may decline more rapidly at some times and slower at others. For further details, read the CHECKING STATUS AND HEALTH section of the following link. The link below should answer most, if not all, of your battery/charging questions.
If you haven't already done so, I highly recommend you take the time to read it. Apple Notebook Battery FAQ
I don't know. But my MacBook White (2010) 34 months, 586 cycles and 79-81% health.
This is my 13" 2012 MBA ...
53 cycles and 93% health on 2012 11" Air.
449 cycles 1.8yrs 80-83.4% over the past 2 days.
Does this need a Poll????
MBA 2011, 22 mths old, 177 cycles, 93% (6230)
This figure fluctuates between 90-93% all the time.
My MBA Rev 1 (2008) had over 600 cycles and was around 88% last time I checked and had been around 88% for about 4 years!
I wouldn't worry too much about the % unless it starts to drop.
EDIT: I just checked my MB White 2007 and it has 96% after 767 cycles....it's been pretty consistent for many years....it's just the battery only last 2 1/2 hours
On rMBP, but i remember them talking about improved battery life on this one.
Mine had similar numbers until it bloated and finally died. This number does not mean anything, because the battery has no "intelligence". The batteries of newer Macbooks (I think Apple started with these variants when they introduced soldered and non-removable batteries) are chipped and remember the cells which are either defective or not been loaded for a while. That's the reason why we now have accurate numbers on the condition of the battery. As for Mac7 I suggest that he completely discharges the battery at least one time. Doing this a couple of times a year greatly enhances the overall life-span of the battery. That's even Apple's advice on their website.
It is never necessary to completely disgarge the battery, and doing so will not enhance the lifespan. That was only recommended on older Macs with removable batteries, during the calibration process. The built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration like the removable batteries in older Apple notebooks.
Edit: Did the picture wrong... so posted below
2010 MBP here, just for reference.
Yours seems fine. The health actually can fluctuate quite a bit. Some days mine's 70%+ capacity, other days it's like that.
Picture properly attached here!
2012 I5, 1 yr old, 104 cycles, currently at 92.1% (6170 mAh)
Normally fluctuates between 90 and 93 percent.
Got mine around the same date as yours
Same config too ^^
Here's mine. Kind of surprised I don't have more cycles given how often I use it on the go.
The Air is the best computer I've owned. It's a pleasure to use...lightweight, fast and reliable.
How do you like yours?
Macbook Air 2010 (33 months old)
150 Cycles - 96% battery health.
im very impressed, and to actually see some people hitting over 1000 cycles is also very impressive.
2011 MacbookAir (bought aug 2012)
i5/4gb ram/128gb ssd.
1.2 Years old
Current Max: 6103 mAh
Factory Max: 6700 mAh
Not so good, I'm going to start a thread in a bit.
Processes have been getting stuck on ~100% cpu usage for a few months now and have to be ended in activity monitor - Installed a variety of clean OS's on it to figure out where the problem was coming from to no avail.
Here's the problem though;
- Computer doesn't turn on one morning
- Bring it to Apple, computer exterior and interior checked (had to wait a week for a rdv with a tech)
- Agreed on replacing the motherboard (all under warranty/applecare)
Today I received a voicemail from the technician stating that he started the repair, but has discovered substancial liquid damage, hence the repair is no longer their cost, but rather mine.
How do I proceed?
It's not possible for a motherboard to be alive under stress for months with "substancial liquid damage" until one fine morning when it gave up (as far as I'm aware)
