I changed my MacBook's (white, plastic) battery after using it for the first year. I've been using the new battery for about 2 years already and iStatPro and System Profiler shyows that my battery's health is "100%". Btw, I'm using the first launched MacBook (white, plastic) which is MacBook 1.1, if not mistaken.

Things about rechargeable battery is when you keep recharge it when it's never depleted, the memory somehow get "mixed-up" or forgotten how "deep" it can go (the full capacity). So, by doing a complete "charge cycle" (full charge then use it until your mac goes to sleep itself) will help to refresh the memory.
Since you're are pretty sure you've done full recharging I think the reading should be correct. To my understanding, in order to able to get claim for battery it must be depleted to below certain % at certain period of time. Anyway, if you still unhappy with the battery, you should call up AppleCare helpline instead of waiting for our reply in forum. All we can do is type & click, that won't help your battery. |

it's always advisable & in good care to take out your battery if you're using your laptop while it's plugged-in to a power source for a long period of time. from my own experience, there'll be a deterioration of your battery's health, which i observed using CoconutBattery, back when i was being careless with my macbook pro. initially with a 100% charge, it'll last about 4 - 4.5 hours. now it's more like 3 hours.
so don't be lazy guys  do what's best for your mac. |

Come on, how many times does anyone has to repeat this, DONT TAKE OUT THE BATTERY, it does no good to your battery, it does no good to your Mac. Period. Anyone wants to question this, search and learn. Just leave the battery in, your Mac does not use the battery when connected to AC, and it is safer this way also, just imagine losing power and not having battery in the middle of processing something, ESPECIALLY when scanning your drive etc.so don't be lazy guys do what's best for your mac.Basic battery care:- 1. Use it till empty before charging, not use charge use charge as you like; 2. Charge it till full whenever charging; 3. Leave it in when on AC, just use it up once a while (once a month or so); 4. When storing away your battery (not in use for long time), leave it at 40% charge, not full, not empty. Anyone still not convinced, look at my battery health posted in this thread, 1st page. QUOTE(rx330 @ Dec 26 2008, 12:14 PM) my mbp only abt 3 hours .... not the promised 5 Not promised, but it was rated, and depends very much on the use. Wifi, bluetooth etc. |

Shouldn't remove the battery pack from MacBook/MacBook Pro when your using it because the charger doesn't charge the battery pack once it's full (green, 100%). Also, removing the battery pack and using it directly from the charger will cause your MacBook/MacBook Pro to run in lower performance mode due to the lack of power. You see, the MacBook/MacBook Pro draws power that can't be supplied through the charger itself so it requires help from the battery pack. Hope I've helped. |

i do calibration once a week or sometimes once 2weeks depend on my usage.
my macbook black is 9months old and 23 cycles, battery life still in good condition. also, dont take out the battery when u using it and on power cause it will reduce the performances. sometimes my macbook show i got 8hrs if usage when i turn on but when u start using it...it gets to 4-5hrs..... so pls do calibration once a while to let the battery "juice" flow... |

Not a life and death issue ler...
QUOTE Display options missing Apple appears to have left some components out of the Mac OS X 10.5.6 release. So far, users have noticed the battery menu does not have any options to switch power modes, and users who connect to their TVs do not have any options for enabling "Overscan". Some users have tried removing various preference files, creating new user accounts, and changing system settings, but those attempts have not worked. As with the battery menu, the lack of this option seems to be an oversight on Apple's part, and hopefully it will be added back with a future update. http://www.macfixit.com/article.php?story=20081218235352708 |

you can use appcleaner for uninstall, which is a freeware.. you can still use drag and drop method, but i think by using appcleaner, it is better as it uninstall the program thoroughly.. about the update...it actually fixes some bugs,security and stability issue...i think it's ok to update it, the performance selection problem at the top right of desktop can be done manually through system preference and accoridng to civic 98, they will put it back for the next update. so just update it.. |

If I am not mistaken, Coconut Battery detects the age from the day the Mac was manufactured. Thus the older age compared to purchased date. You could otherwise match with Serial Number for the production week/code. |

I just bought a 2nd hand MBP (9 months old).
Using Coconut Battery, it says battery loadcycles = 42, maximum battery charge 4911mAh, maximum battery capacity 5500mAh. That's around 89% in terms of battery health. Is this normal? If not, can I make a claim (replacement battery) from Apple Malaysia? Thanks in advance. Jack |

Hi guys. I found out this forum and says that my battery cycle count is 181 and condition : check battery i am using macbook pro and it's charging while i'm viewing this. any advice?
UPDATE : I used CoconutBattery and this is what I got. Anyway I can undo this. Can the tech guys at Apple help me or simply I just need to buy a new battery? Sigh. I am currently charging it. This is my battery.  This post has been edited by winmac: Jan 5 2009, 12:33 PM |

Yeah, just called Apple and they say that all parts of the Macbook Pro are protected under the ACPP except the battery as it is considered as consumables. I guess that's fair.
Just curious. I forgot to ask the tech support guy. When the battery is fully charged at 100%, and we still plug it in, will it affect the battery life? Someone suggested me to remove the battery first before letting it run on power as it will affect the battery life. Any idea? Thanks.

it won effect the battery life, my past eperience of notebook is to unplug once its full to let the battery tahan, but for apple lain the best is keep it one power cord whenver possible, hence the lesser battery cycle consume |

there is higher possibility of hardware failures such as motherboard fries if u dun plug in the battery while using AC. It's because sudden variation of electricity (from the electric socket) may produce voltage peak which will damage ur hardware.
Don't you notice sometimes at home, the fluorescent light seems like blinking in short interval? probably 100ms? which u'll hardly notice. So best is plug in battery all the time no matter what. It won't overcharge since apple battery will only recharge when the battery level drop to below 95%. To those who think that they have zero or low cycle count after a few years of usage will make ur battery life longer. NO, the chemical inside the battery will deteriorate after a couple years, perhaps after 5 years u'll change another laptop already. So don't be stingy on using battery |

@tanjq87 Thanks for the useful info.
@ghoul88 I think that is way too cool for 19 month old macbook battery. Just look at mine. 25 months and registering only 181 cycles but already left with only 53% battery life. But that's not too bad actually. I can still live with it ;-) In another 2 years, I could change to a new macbook. |

Totally agree.. the battery will start to deteriorate right after it is being manufactured. This is no doubt the case in all battery lifespan. But with proper care of the battery, we will be able to prolong the lifetime..

Hehe. Even if you run the machine without plugin in the battery, you have that gut feeling that its wrong / something could go wrong. Previously I was under the assumption that Apple will cut the supply to the battery once its full and will run the macbook on direct power instead. That's how advance I believe Apple is and that's why I never took the battery out even sitting on the computer whole day while its plugged in. I could be wrong though. Haha.

my MBP's (bought June 2006) battery can go as low as 18% sometimes, then the notebook would have problems booting up a few times in succession (had to try like 10 times) but when it does boot up, the battery is at 38%.
after a few weeks, it'll slowly do gown to 18%, has the booting problem, then up to 38% again. any ideas? |

I remember last time (4 monts ago) I watch anime with my MB when I travel from JB to KL, and that day caught in slow traffic, so took me about 5 hours to reach. And in that 5 hours, I was watching anime all the time, until I finish my anime...I still got battery for me to do other stuff like go online with my usb modem for about 1 hour maybe? I set my brightness to 1 bar, using earphone, bluetooth n wireless off. From my experience, my MB is able to reach 4~5 hours when browsing on wifi and doing some typing. depends on what program u are running. |

I never use my mbp battery since the day I bought it. As one of the Apple technical guy, I always trying to avoid using battery. Believe it or not my battery charge cycle is still 0.

I use MagSafe adapter all the time. My boss also didn't recommend me to use battery when I'm at home or office. Even if I go to starbucks, I'll search for wall socket.
I'm thinking if one day I sell my mbp to get a new one, at least the battery can help to boost up the price. |

Good question. If starbucks run out of wall socket, I'll just sit there with a cup of ice blended mocha and wait till those wall socket to be available. I ever bring an extension socket to starbucks and shared with other people. No a big deal. As long as everyone is happy.
Battery won't charge after didn't use for 1 year? Guess what? You must be using it on and off right? If you already use your battery, it is good to use it once in a while. Unless you are like me, which I never use it or charge it since the day I got it. |

Not really. Like I said, if you have used your battery, continue using it. Until your battery is dead and when you get a new one, if you plan not to use battery at all, then just leave the battery out there. Don't even charge it when u first get it.

I thought the current advice is to leave the battery in while connected to a wall socket? it was discussed in the previous page. It was said that the battery helps to prevent fluctuations in voltage which could "fry" the mother board especially when there is a power surge.
I would think the safer option is to have the battery in while the Mac is in operation. |

Well, my battery is currently at a lovely 65% capacity, with 443 load cycles (at least I think that's what it's called). Sucks, but to be honest I hardly every use it outside and when I do, it's only for about an hour max, so it's still good. Still, it isn't nice knowing that your battery isn't as 'juicy' as it used to be
I'll toss this one when snow leopard is released, hopefully with a MBP that doesn't have that awful black frame  |

well , u should know that the fact that the battery is going weaker even u have never use it. that is the characteristic of li-ion battery . from day 1 out from the shelf , it is deteriorating, the cell inside it has to be actively charged , that is why the recommended shelf keeping charge is 50% .

A little review to share~
Li-ion batteries have a higher energy density, higher cell voltage, low self-discharge and very good cycle life, and are environmentally friendly as well as simple to charge and maintain. Lithium is one of the lightest metals, is one of the most reactive and has the highest electrochemical potential, making it the ideal material for a battery. A Li-ion battery contains no lithium in a metallic state, but instead uses lithium ions that shuttle back and forth between the cathode and anode of the battery during charge and discharge, respectively |

Yea, different people different opinion, and some just like to run their notebook slower than it is supposed to. Paying for the battery and not using it, SMART.
Here are some searches that may interest some:- http://www.google.com.my/search?hl=en&q=ma...le+Search&meta= And this from Apple:- http://support.apple.com/kb/HT2332 QUOTE If the battery is removed from a MacBook or MacBook Pro, the computer will automatically reduce the processor speed. This prevents the computer from shutting down if it demands more power than the A/C adaptor alone can provide. This post has been edited by civic98: Jan 31 2009, 03:11 PMAdditional Information Important: It is strongly recommended that you do not use your MacBook or MacBook Pro while the battery is removed. Accidently bumping the A/C adaptor could disconnect power and shutdown the computer. Any information that was not saved on your computer would be lost. |

Hahaha that is true but I guess so far I'm lucky enough that no one bump into my a/c adapter. By the way, i do use power surge protector. so no big deal at the moment. Unless I go to starbucks, hmmm... should have gotten myself a portable power surge protector... hmm..

QUOTE(ryley7 @ Dec 26 2008, 12:11 PM) it's always advisable & in good care to take out your battery if you're using your laptop while it's plugged-in to a power source for a long period of time. from my own experience, there'll be a deterioration of your battery's health, which i observed using CoconutBattery, back when i was being careless with my macbook pro. initially with a 100% charge, it'll last about 4 - 4.5 hours. now it's more like 3 hours. dont give idiotic adviceso don't be lazy guys do what's best for your mac. |

The battery thingy is really stupid. Yerterday i switched off my MacBook and the magsafe before i went to sleep. Then this morning when i turned on my lappy, i forgot to switch on the Magsafe 1st, guess what, for the split second when i went to turn it on, the battery is already down to 98% and charging lol. It drains out so freaking fast man xD

Cycles: 14
Health: 100% Run on battery power at least once per week, else on AC power. Perform Battery Calibration once per month. I do hope the Battery Health could stay good and achieve 80% health at 300 cycles like Apple claimed.

I have the drain issue as well, pretty fast drain if you ask me. I'll usually let it drain till about 90% or less and then charge it. One weird thing is, charging from 90% to 100% takes quite long, like an hour or so...

Standard Maintenance
For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her MacBook Pro on the train, then plugs it in at the office to charge. This keeps the battery juices flowing. If on the other hand, you use a desktop computer at work, and save a notebook for infrequent travel, Apple recommends charging and discharging its battery at least once per month. Got the info from here:- http://www.apple.com/batteries/notebooks.html Apple say Don't Plug in always. People say leave AC Plugged in. This post has been edited by blizzzy: Sep 13 2009, 11:04 PM |

One weird thing is, charging from 90% to 100% takes quite long, like an hour or so... This is normal. I'm guessing the mac's charger uses a constant voltage (CV) charging method towards the later(ending) charging stage. The charging current will logarithmically become less and less at the battery reaches the peak voltage. This is certified to be the safer way to top up a li-ion battery to it's maximum capacity without overcharging it.The earlier stage of charging uses a constant current (CC) method to provide the maximum charging current at a fast constant rate which is why it charges much faster before it reaches the point where the charger switches to CV charging mode. That is I'm assuming that mac's does it this way as most modern chargers do. |

Just received my MBPro 13". Need advise whether to charge it to full first before on the set or can straight use the MBP? Question is to enable proper battery usage and longevity of the battery. Advise please.

QUOTE Built right into each of the new MacBook Pro notebooks is a breakthrough battery that lasts dramatically longer and does so without increasing the size or weight of MacBook Pro. On a single charge, the battery in the new MacBook Pro lasts up to 7 hours (8 hours on the 17-inch MacBook Pro)1 and can be recharged up to 1000 times.2 That’s compared with only 200 to 300 times for typical notebooks. Advanced chemistry and Adaptive Charging allows the battery to maintain charging capabilities longer and determines the optimal way to charge the battery’s cells. Because the battery lasts up to five years, MacBook Pro uses just one battery in the same time a typical notebook uses three. That makes for less waste. And that, in turn, makes for one environmentally friendly battery. the new MBP battery seems to be able to charge upto 1000 times compared to regular which is 300 times before it reaches 80% sos : http://www.apple.com/macbookpro/battery/ This post has been edited by jinaun: Sep 14 2009, 10:55 AM |

Don't forget, the batteries don't get charged if the notebook is plugged in 24/7.
It's a myth that the battery will keep charging if plugged in. All consumer devices with lithium-ion batteries have proper protection and charging circuitry. Because any lithium-ion cobalt battery that is overcharged or overdischarged can turn into a bomb when it experiences thermal runaway. The only enemy to the batteries are heat. |

yeah apparently the macbook battery doesnt exactly charge even thou its plugged into the ac 24/7.
urm read it somewhere, so i dont knw to what degree this statement is true. but the adapter is not connected directly to the battery. thats why when you flip the mac the other way around, the adapter is at one end and the battery is at the other. there is a chip that only lets the battery charge when its not full. when it is, the power go directly to where its needed and not to the battery first like any other device is designed to. yeah but keep in mind that i read this of sumwhere and im not to sure of how true this is.hahha think the sifus over here will prove the statement after i post this up. |

Lemme shed more light on Li-ion/Li-polymer batteries.
BTW I'm new in this thread. Our macbook's use Li-polymer, which is basically the same as Li-ion but is not round therefore you can have more capacity per volume(if cells are cubic in nature). Li-ion's are basically round cells and therefore have less capacity per volume. Li-ion's have 3 enemies. Heat, time and (strangely) capacity. Hotter = die faster Longer = die faster The more charge it has = die faster (to a point only) Storing @ 30ºC for 1 year, your battery will lose it's capacity faster than @10ºC for 1 year if both are at equal charge. Storing @ 100% charge for 1 year, your battery will lose it's capacity faster than @50% charge for 1 year if both are at equal temperature. And of course, storing for 1 year, your battery will lose it's capacity faster than storing for 6 months if both are at equal temperature. Li-ion seems happiest @ 40% charge, low temperatures. Also, li-ion seems to not like cycling 0%>100%>0% Oh well... Someone correct me if I'm wrong anywhere. Oh ya. Forgot my battery. Just ran a cycle a week ago I think. Ori capacity: 5020 mAh Current capacity: 94%(4731 mAh) Loadcycles: 261 Age of Mac: 21 months Pretty good I'd say. This post has been edited by polkiuj: Sep 23 2009, 10:10 AM |

I keep the AC plugged in most of the time unless I'm on the go; but as to your question I might not be the right person to answer it cause my system's usually on |

yes its correct. Do get your info from www.apple.com/batteries
my experience is that it will re-charge only from 85% or thereabouts... EDIT : typo This post has been edited by xaw5126: Sep 24 2009, 07:51 PM |

Actually not only charge cycle determine the battery life. Soon after the battery left the factory it's life is decreasing. So no battery will last forever (at the moment). It's just a matter when will it happen.
Having a good practice on usage will prolong the life. For all new MacBooks, the battery is internal and meaning it's connected whole time so discharge happen even you are not using the Mac. I'm happy if the battery lasted 3 years. Else I got ACPP. |

 Does this mean that my macbook white's battery is dead? In fact when I turned around the macbook and try to press the battery light indicator, there is no sign of light coming of. If it's dead, and if I don't have ACPP, what can I do? Can I call Apple and ask for servicing? If in this case, approximately how much will they charge for it? Thanks in advance for any help. |

dvlzplayground,
i think i get it when qwertypolle said the health increases coz after calibration it will show the correct percentage of battery life. it can go up or down.. it has happened to me before.. sometimes after calibrating, it will go up from 95% to 99%, but this happened a while ago when i just got my macbook. |

Did you try to revive your battery by putting it in a fridge and reviving it. It may work , and try to run Coconut battery , it will tell you if its good to go or not. You can google or watch a video over at youtube on how to revive your dead battery. Generally it give you say 5-10 minutes of battery life
Take a look at its health and get the most accurate info from Coconut battery 
If you want to save few $$$ , then refill the battery cells. There is a shop in lowyat which does this. They'll take your battery and "refill" her up. The thing is that the mac has an EC which may not like if the battery is refilled. You'll have to google up on this to check if its good to go. I truly understand that not many of us could afford the battery as its overpriced. I'll ask around for you and let you know if there are other alternatives |

The purpose of calibration is to reset your macbook's battery meter so that it is accurate. Hence the term "calibration" In fact, calibration will usually decrease battery's capacity by a little bit as lithiums do not like to be over-discharged. Here's my battery few days after calibration. Hmm... can't upload.. oops. Type out la. Current cap. = 4668 mAh Ori cap. = 5020 mAh Capacity left = 92% Load-cycle = 313 Age = 24 months Hey not bad =P |

hi,
I am sorry, i am new to mac as well, I have MBP 15inch and i can't seem to find the charge cycle. my battery life always show 96% eventhough i am still charging it.. Is it okay to keep charging my MBP as i always leave it at home, hence the plug is on 24/7. I do off it sometimes to drain the battery.. Hope my actions are not ruining the battery life.. another thing is, the website says battery can last up to 7hours, yet when i bring it out, it only last about 4-5hours max. |

well, you wont wanted to always take out and put in your battery, dont you?
you dont want to waste your battery cycle, dont you? so, just plug on the power, nothing to worry when you see charged, mean battery fully charge, when your mac will use direct power from adapter. better or not.... well i manage to have batter battery service period. My dad fren did the same as you, his battery kaput after year plus. They bought the mac almost the same time. So, how do you think? |

QUOTE(digilife @ Jan 2 2010, 08:51 PM) if this is my battery condition, can it be recondition back to better life as the battery loadcycle is kinda low Sorry, there is no way to regain lost capacity on Lithium batteries as the chemistry is like that. Only option is to get a new battery.
if yes, how can i do it thanks You should check if your battery is really at that capacity though as it is un-naturally low. It should be more than 50% still. Is this after a calibration? An uncalibrated reading might not be accurate as some charge can be lost during the charging/discharging process. QUOTE(hyumi @ Jan 3 2010, 11:49 PM) hi, Yes it will ruin the batt if you keep it full all the time. This is just the way Lithium batteries work.I am sorry, i am new to mac as well, I have MBP 15inch and i can't seem to find the charge cycle. my battery life always show 96% eventhough i am still charging it.. Is it okay to keep charging my MBP as i always leave it at home, hence the plug is on 24/7. I do off it sometimes to drain the battery.. Hope my actions are not ruining the battery life.. another thing is, the website says battery can last up to 7hours, yet when i bring it out, it only last about 4-5hours max. Battery life depends on what you do. If you want to leave your MBP at home all the time, I suggest you get a desktop. If you really want to maximize your battery life, there is one way. Discharge it to 40%. Then store it in ur fridge. 40% seems to be the optimal capacity to store a Li-ion based battery and the lower the temp, the better. Not too low like freezer. Fridge should be fine. QUOTE(digilife @ Jan 4 2010, 01:07 AM) wont tat "kill" the battery faster? Yes, keeping it full will kill it faster.cause tat was wat happened to my acer battery last time or acer battery system is different?? And please, Acer and all other companies battery work the same. Even the charging algorithm is the same as Lithium cobalt based batteries are very explosive prone and is not happy with weird charging algorithms. If charge is not cut by the time the batt reaches 100%, it will (soon) overheat and blow up. *BOOM* Acer and all other companies do have a separate problem though. The battery is usually kept together with all other heat producing components. So the battery will naturally not last as long. Apple (being the genius they are) has kept the battery far away from all the "battery assassins". Therefora a mac battery usually lasts much longer. Hooray to Apple! =D Here's my batt. Hmm... it refuses to let me upload.. =( Charge Information: Charge remaining (mAh): 2409 Fully charged: No Charging: No Full charge capacity (mAh): 4636 (of 5020, 92%) Health Information: Cycle count: 318 (age: 24 months) Condition: Good Battery Installed: Yes Amperage (mA): -1387 Voltage (mV): 11236 This post has been edited by polkiuj: Jan 4 2010, 12:14 PM |

What is the implication if i turn on my MacBook Pro 13" for hours and hours with charger on? Maybe days, because i need to burn in my headphone if u guys know what i mean. Also, what happens if we don't have AppleCare and our battery doesn't work?Can retailers help us change the battery on the spot?

Those are nice headphones you've got there. I have the SR225 myself.
You could just plug it in to a radio or portable player if you don't want to keep your Mac on. |

The only portable player i have with me now is the iPhone. I wouldn't want to mess with the iPhone either, because i dont want it to have a shorter battery lifespan. You know how fragile the iPhone is

Hi all . I have the 15MBP bought 2 months back. even at full charge I get about 6 hours of "projected" usable battery time. I only have finder, firefox and wifi running. the screen is down to the minimum and the keyboard lights were off. I tot it should average about 7-8 hrs of common use??

Is it each calibration on the battery cycle, the mAh on the battery will drops? Mine battery is 4800 mAh. Current is 4646 mAh Today is at 28 cycles. is there a way to maintain or slower down the mAh ? |

For unibody model after 2009, you can keep the charger connected all the time when you use your Mac. My new battery was bought 4 months ago, still at 101% capacity. But I had a massive drop like +-200mAh once I disconnect the battery from the logicboard. No calibration done it. I'm planning to keep it this way just to experiment.

sorry mistyped~! it's around 20 cycles from my case.
Added on November 20, 2011, 3:39 pmPerhaps my conception is wrong about calibration is to maintain the mAh as possible as it is. I am using mbp late 2008. I got new battery replacement somewhere around this mid year. Couldn't remember that well. This post has been edited by dinodog_Jr: Nov 20 2011, 03:39 PM |

Since new polymer battery don't suffer from "memory effects" I wonder calibration is still valid. But Apple recommend it. since I'm off with my experiment, I will report back in couple months.

i dont think it has anything to do with the memory effect. my guess is the battery would have a sensor that reports how much charge is remaining, and the calibration is to calibrate the sensor, not the battery itself
well u're the pro lah that's just my impression |

Heh, me no expert. But Apple batteries do have some extra components. You don't see normal batteries reporting health, model #, manufactured date and firmware update if needed.

The new Mac battery quite high tech, you can plug in and out whenever you want, once it's done charging, it will switch to cable mode, no longer battery

Did you try to do a recalibration?
Try charging till full, then keep running off AC power for 2 more hours (after fully charged). Then use macbook as usual until battery is depleted and it goes to sleep. After that switch off the macbook, leave it in that state for a couple of hours before fully charging it again. My current full capacity is 5643 mAh, charge cycle 18. |

Hello.
I just bought a macbook air 13" last monday and i installed coconut battery but the program said that my mac age is 7weeks. Why is that? In this 6 days i've charged for 5 cycles already. im not very sure what is all this cycle or keep it plugged in about, i've read the thread from apple forum about preserving the battery but there is no accurate info on whether i should keep it plugged in or use till 1% and charge till full 100% if i continue to do as i usually do (drain to 1 then charge to 100) the cycle will increase drastically. so which should i do guys? sorry if this question is repeated over and over again but i've read alot of topics but there is no specific answer. |

I will definitely have more than 1 cycle in a month cos i bring my mba to uni (of course with fully charged battery) but whenver im home it will be around 50% or so, so i'll try to use my mba and drain till 3% then charge full so i can bring to uni the next day.
am i doing it wrong? or i should instantly charge my mba when im home at 50% or so? |

I just plug in whenever I find a chance. I don't appreciate the moment to desperately look for power source. Anyway Applecare will cover if it goes wrong. |

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?

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? |

QUOTE(invisiblelim @ Jul 25 2013, 10:01 AM) after reading thru the posts, this is my understanding on the battery usage. Depends on the battery life. If it is above 95%, it won't charge even if you've plugged in. 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? 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. |

QUOTE(rx330 @ Dec 24 2008, 03:02 PM) guys, im using my mbp for less than a moon, judging from iprostats, my battery health is only 96% is usual, my battery max is 88% after one year caz i never switch off~ was readin from macenstein blog just now, the blogger has been using his mbp for quite a while, but his battery status as written by him is still 100% problem with my batt? 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. |

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. |

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? |

Actually, why is the repair price is so over for Apple? Repairing Macs can be expensive and FYI, replacing battery on your current MBA will cost you around MYR 500+, IIRC. May I know, what application are you using to protect your Mac? Beside this, due to the needs. I am thinking of install Microsoft Office on MacBook, but some of the people told me this might slow down the MacBook. Is this true? I tried to search on internet but answer supporting both side yes and no. |

If you are using 2 pin plug (US adapter), you will usually have this "shock". |
