8 hours charging time

[Evolesque]

hey,

I've had the eight hour charge occur to me too, however it seemed to have gone away after a couple of charges. Not to make any speculation so I'll just post what happened to me. At first when I bought it, it charges fine. Then about a couple days later it started taking forever to charge 8hrs...Now it's back to normal another week later. I also notice my battery went from 4819 now to around 5000 in charge at full. I also notice now the battery will stop the charging sometimes at 96 or 100 percent but it's not consistent. But no major battery issues now except for inconsistent full charge. Maybe your going through the same thing?

Well guys

This is my first post on macrumors so hello everybody. I bought a macbook air just over a month ago and am loving it. Last week i let the battery run until the computer shut down and since then it is taking me 8 plus hours to recharge the battery. Before that it was not taking any longer than 4 hours. I'm worried that battery may be permanently damaged. Is emptying the battery completely of charge bad ?

Thanks for the help.

Since the wattage of the adapter is so low, and if you are using your computer, the computer has to devote more of the AC power to powering the machine than charging it; if you shut it down and charge it, I'm willing bet it will be a much faster recharge.

no way ! I'm never going back to windows again. I am definitely a convert. Is it better to charge the air while it is awake, asleep or just powered off ?

Thanks

He said go back to a PC, not go back to Windows; there is always Linux to go to

reset pram

Hold Command + Option + R (I think ) upon starting the machine and release them when the machine restarts (you will hear a noise).

that's not correct. must hold P also

slow battery charge

seems to me like it takes forever to charge. then after sleeping all night there's no battery in themorning, but I haven't calibrated it yet.

Linux: The unsung hero of the computing world. :[

I think when I get my MBA I will be putting Linux on it before windows XP.

It takes long time to charge here as well. I didn't bother timing, but it's always very long from discharged battery to full. I suspect the A/C adapter is quite weak and made like that only so it can be as small as possible. I wish they'd release a bigger one that I could keep at home and charge the battery quicker.

problem solved I think guys. Basicly don't let the battery go below 10 percent and it charges normal for me anyway. Thanks for all the help.

 

[yoomy]

i had the problem for the first month, sometimes it charged quick (4 hours) but most of the times it took at least 8 if not 10 hours to charge. apple finally replaced my battery and it always charges fast now, no exceptions.

 

[darngooddesign]

If it really annoys you buy one of the regular high-power chargers from apple and use that to more quickly charge the battery

Is that actual advice? I'm curious.

Yes, but it means you actually have a 90% usable charge on top of the wildly optimistic '5 hours of wireless productivity' nonsense. I cannot understand why so many people rate this piece of @#$£ which even stands above the other pieces of @#$£ I own from Apple so highly. Do that many people think purely with their eyes, I wonder.

just a quick question guys. I'm bringing my first gen macbook air in to genius bar tomorrow. It takes more than 8 hours to recharge it. I can't stand it anymore. Is there any chance they'll do anything to rectify situation or am i just wasting my time. Thanks

 

[iann1982]

Mine took about that for its first few charges, but it was quickly down to 3-4 hours after a few charges... I don't think the battery should take longer to charge than it does to dis-charge? surely that's not right?

go to the apple store and ask for a new power adapter...this is the issue 9 times out of 10

again, take it to the gbar and tell them its taking 8 hours to charge your MBAir battery...they'll give you a new charger

So at least three of my chargers purchased at different times in different continents were faulty? Either way it's

if you've gone through 3 different chargers then you're that 1 out of 10..

you need your magsafe assembly replaced...simple repair for the gbar, if they have it in stock...if they don't, tell them you wish to do a 'service non-repair' so you can keep your machine while they order the part

No - not through. Simultaneously, and more in fact. Due to the pathetic battery life of the Air and the whole point of an ultraportable meaning that I don't have to walk around with supporting paraphenalia (at least as far as my Sony's are concerned), I had chargers liberally scattered around the place. The three I refer to were just my home and one of the places I work at, and I had the same issues with all - on both of the Rev A Airs I had, both of which were booked in to the Genius Bar of four Apple Stores in three different countries several times for this and stability issues, on every occasion the machines being pronounced 'working OK'. The Rev B didn't go in for power exercises as I encountered similar stability issues in warm ambients and I ditched it with much less patience than the A.

It should be pointed out that due to aforementioned pathetic real-life endurance of the Air, I ended up fully discharging it every time I went out with one and this was when I frequently got the 8+ hour charging times. Given that, I somehow doubt it was an individual lemony issue. If it was, Apple QC is even worse than my current shoe-sole-level impression of it

seems like the air wasn't the machine for you lol

that and coolbook might have helped a bit with battery life...but yeah, if your air is taking 8+ hours to charge, with multiple power adapters...you need a new magsafe assembly...end of story

whether the gbar techs caught this or not is another story...

 

[Sesshi]

In fact, I'm in a position to see what they do pick up this time. One of my erstwhile Airs is baaaaaaaaaack and will be hitting Applecare with a vengeance.

(Personally, I'll be angling for a refund - although I will probably settle for a Macbook replacement + vouchers for rest - to likely spend on 60W adapters instead of 45W )

Nevertheless, I'll take your advice on board and mention it if the situation warrants, thanks.

I usually don't actually say anything beyond describing the symptoms - and it has to be said that the Airs are one of the few occasions on which they have repeatedly not replaced any parts and declared it meeting spec, despite the issues occuring. On most Macbook Pro related issues they have replaced parts, which it has to be said in many cases made things actually worse, without (sometimes) solving the original problem. After a few times of that, I sometimes get directed to an AASP who in some cases have better luck. But they have at least changed out bits to see if that makes a difference. It's the lack of this effort on the part of the Airs which I thought was uncharacteristic of my repair experiences.

Naw, we just use it on a daily basis and it works beautifully for us. It's a great machine that works great for many of us.

Yes - and I'm sure netbooks with 2-hour runtimes may seem to work great for many people too. That isn't necessarily the point.

Of course it's not the point. We are not talking about netbooks. We're talking about an incredible piece of computer wizardry called The MacBook Air.

I'm sorry that you had a bad experience.

But, it's YOUR experience.

It has not been mine, it has not been many other folks. And it doesn't just "seem" to work great. It works fantastically.

Good luck in the future.

No YOU are. I'm talking about the incredible piece of flawed form over function called the Macbook Air.

Clearly we arrive at our conclusions from different paths. I leave you to your completely undemanding Mac ownership.

That is the point. You had a bad experience with a computer. 1000's of others have had a great experience.

>I leave you to your completely undemanding Mac ownership.

The point went right over your head. You are wrong, I am a demanding Mac owner. Your experience is only your own. You do not get to speak for others.

Good luck.

Read this thread yesterday and decided it was about time to condition my battery. It has shown 97% health from Day 1.

So, ran it down yesterday evening web browsing, reading .pdf files, working in Numbers and listening to music, lasted about three and a half hours. Just before it died I closed all programs and then let it send itself to sleep.

I then did the same and left it unplugged overnight.

Plugged in at 7am, still in sleep, and by midday it was charged, opened the lid and woke it up ten minutes ago and still my battery shows 97% health! Only 6 cycles and one conditioning cycle in three weeks
