Guys, how bout mine? I remembered reading somewhere bout how to take good care of battery and currently, im practising :-
-Plug my MBP to the charger all the time but maintain 2 cycle of charges a week
- Every 2 months I recalibrate it once

hi. just want to ask. i am new to mac and am using macbook air mid 2012. so, i have checked with istatpro, and it states that battery health is 97% and cycles is 13. is it ok?

thats normal

My daughter end-2009 MBW has "Service" showing on the battery, two options given by VRTech, replacing with stock = RM523, exchange = RM431 .. almost RM100 different .. but exchange means that the notebook need to be with them for a week. Worth it?

buy new MBA... starting from 2999, battery life start from 9 hours... all spec is upgraded... got tax deduction also... and problems all solved...

after reading thru the posts, this is my understanding on the battery usage.

whenever i was at office, i keep my MBA charged or with power plugged in.

when i was on the move, i will just use my MBA until i go home or office then charged it..

another enquiries, if example i had finished appointment and go back office, but i not plan to use the MBA, do i need to charge it? or only wait until the next use on plug in the power?

Depends on the battery life. If it is above 95%, it won't charge even if you've plugged in.

Based on my observations, I will only charge the battery if it is below 40%, the less charge frequency the better. Not sure if others feel the same thou. But that will not consider as one charge cycle, if you charge it from > certain % of battery left.

My current capacity even higher than design capacity !
Anything goes wrong ?

It is perfectly fine. It will deteriorate once your Mac is aging.

my battery condition after using for 1 year, its a 15" rMBP

I'm using macbook aluminium 2008. Below is the btry info taken from System Profiler. Surprisingly it still lasts up to 1hr 10mins on a full charge.

Health Information:
Cycle count: 306
Condition: Poor

is usual, my battery max is 88% after one year caz i never switch off~
capacity stuff u need to calibrate~

Calibrate the battery once every 1-3 months
Finally, if your battery is showing signs of shorter run times, you may want to calibrate the battery (once every 1-3 months). To calibrate the battery, follow these instructions:

a) Fully charge your MacBook.
b) Once fully charged, leave it plugged in for at least another 2 hours.
c) Remove the MagSafe power adapter, and use your computer until it reaches around 5% remaining.
d) Plug in your MacBook and charge it to 100% battery life.
e) Once fully charged, your battery has been properly calibrated.

Thanks for the guidance, but that post was made since 2008
since then my mbp now is running on charger with no battery in it
The battery went bloated few years back

94% consider good result

btw,i dont think apple wants our macbook to be plugged all the time
use the battery often to keep the electrons in it moving occasionally,like mine ald 201 cycles still 94.8% (calibrate once within 1/2 months)

my bad experience :
keeping my macbook plugged all the time and then around 9-10 months my battery show 'service battery',below 80%,lucky its still under warranty,they replace a new battery for me

my practice:charge till 100% and unplug it after 10 mins,use the battery,when doing heavy duty,must plug in
my result:
201 cycles
94.8%

haha~ sorry i didn't know that tips was be here since so long ago~ but just sharing for others newbie like me~ haha~ XD

Hello friends. I would like to ask is it normal for Macbook Air maximum only 4 hours and 30 minutes for 97 battery charged. I am currently using A1370 EMC 2471

Hi,

For a 2011, A1370 EMC 2471 (11-inch) MBA, that sounds pretty normal.

Plus, the 2011 model is almost three years.

The battery life for a 11" MBA (2011) :

Up to 5 hours wireless web
Up to 30 days standby time

I see, thanks for your information and afford. Because I thought Mac Air can last even longer and my battery life cycle 2++
In other words, even though i send to repair or replace my Air it won't able to last longer?

2011 MBA (11-inch) is designed to last up to 5 hours.

You can replace your battery if it only lasts like 2-3 hours.

The newer 2013 MBA model has longer battery life though.

Up to 9 hours for 11-inch model and 12-hours for 13-inch model.

Even longer on Mavericks, which is almost 16 hours.

Oh my god, what a bad news could break my heart. Thanks for telling.
I am surviving for screen replacement. Since my Air's screen has cracked.
However, I've got some information about this. one of the Apple specialist quotes me 1190 and one that I found on internet only 900 but he said there might be minor uneven, dust or scratch after replace. Is this normal to screen replace?
