I have a 2 year old aluminium macbook and have recently been having problems with the battery.
Sometimes when running off the battery alone, at around 20% battery remaining (or so it says) my macbook suddenly shuts off. After I start it back up the indicator says there is no charge left and shortly shuts down again. After plugging in the charger and checking coconut battery my battery health is suddenly 40% less than the last time I checked.
I am confused as to what the "battery health" of my MBP is. I downloaded an app it told me it is 89% but it is not consistent with the cycles, mAh capacity, etc (it should be more?), so I am thinking the app might be innacure in reporting this (reviews say this). I just want to have a second source to see where I stand.
Info: MacBook Pro, Mac OS X (10.7.3), 17-inch: 2.4 GHz
I bought a 2009/2010 MBP a couple of years ago (still have AppleCare on it) and the battery life on this machine has been absolutely atrocious. I feel like I unplug it from my desktop and sit down on the couch and thirty to forty minutes of web surfing and i am down to 25%. and i have to plug in or I will get a warning that i am under 5% in another 10 minutes.Does anyone know if this is partially or fully due to Parallels? I just checked and with not much running all i see is a prl>vm_app that is taking up 12.6% CPU.
I mean I hesitate to ask this because I ran a test about six months ago by fully charging it and turning it on (no apps running) and my recollection was that it went into deep sleep in about three hours. This was when it was doing nothing.Any facts to measure this against or any way to do an actual analysis on my end? The cats at the genius bar are always like "situation normal" which makes me think there is something wrong with this class of machines or something.

I have searched countless threads about battery health but I feel that each individuals battery health situation is so unique due to the numerous fluctuations.
I have a 2010 13" MBP with battery health of 92%. Load cycle: 13. and Age of 4 months( but i got it 2 months ago)
Should I be concerned with the battery health at this point?
I was looking into buying a new macbook pro and I was just looking at my current macbook 13 inch and I hadn't checked my battery health for a while so I went and had a look. I was extremely suprised to see my battery had done 1046 cycles and according to istat, my battery was at 92% health...
I have had my macbook 13 inch since november 2007. It has been having a few problems lately with over heating but I was wondering if it was normal to have a battery that had gone through so many cycles and still have around 4-5 hours battery life (when I am just browsing the net and doing uni work i.e not watching movies or listening to music)
I've had it for 16 months and the battery has 192 cycles and its health is now 78% (it fluctuates a bit). Is this health normal for this amount of cycles and age?
I have a feeling my rechargeable battery pack was secretly swapped out by another user (whose battery had died) - left for vacation working computer, returned from vacation battery not charging. Is there any way to check (serial number, etc.) what battery came with the purchased computer?Â
Time to replace my White MacBooks battery, the model I have is the A1181. I'd like confirmation that the battery listed below will be compatiable with this Mac and not just newer versions.[ur]
I have the Black Macbook (purchased in 2008) and within the past month, I have been experiencing problems with the battery. I've noticed lately it becoming weak, not being able to last long without being plugged in. However, now when I plug it into the charger, it shows 0%, and if I disconnect the charger, it automatically shuts off. I checked the System Profiler, and the condition of the health shows "Check Battery". What are my next steps from here? I don't want to purchase a new battery, in hopes to get a new Macbook later this summer.  Does my Macbook have much life, or should I go ahead and brace myself for a new one?Â
i am due to send my macbook pro to apple retail tomorrow to check my battery. anyone know how long does it take? i can't leave my laptop there because i need it over the weekend.
i've been getting this service battery icon on my battery bar for a week.
I bought a 3rd party battery for my MBP. I put it in and after cycling the battery i noticed that the full charge capacity was only 3990mAh (supposed to be 5500mAh). I returned the battery today and got and an upgraded replacement. this shows the full charge capacity at 4995mAh (supposed to be 5600mAh).
is this normal. Do I just need to give it some time or is it something with the batteries.
More and more I have this issue both during playback on any iMac or Mac mini or even iPOD where as the volume just goes up and comes down. From blasting my ears to a whisper, and all throughout songs from ACDC, Pink Floyd, classical, Samsh Mounth, etc. Most of the songs are in MP3 from my CDs that I ripped through iTunes. I tried AAC and it does the same thing, and AAC will not playback from my Amazon music account, so AAC is a no-go.
Even so I never had issues in the past when ripping my music through other applications, just seems for the last couple of years I have had intermittent issues ripping through iTunes. Any settings or other adjustments I should or should not have made? These are huge fluctuations that vary (on a scale of 0-10) from 2 to 8. Its that bad. All Systems are 10.6 or 10.7 and intel based.

As the Title of The Post says, i need to know if Apple Hardware check, Does check the hard drive. I'm getting a little bit more frequent hard drive clicks so i want to make sure my HD is not failing. So i need to know as so as possible if Apple hardware check looks for Hard drive Problems. And if it does not. Can someone point me into some Utilities i can use?
I have just completed rescuing a water damaged MB C2D which was originally a 2.16 and is now a 1.83. Fun project for a cold Sunday afternoon. 5 hrs I have one issue with the MB and that is the charging of the battery. The battery icon sometimes shows 'no battery' or if it shows a battery is recognized, it isn't charging. The LED on the mag-safe charger is always green. The battery is from the water damaged 2.16 and my thinking is that it may have suffered damage from being exposed to water. Original owner left the MB in the backyard and it started to rain!
My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.
I calibrated my battery for the first time since Dec. When I plugged it in this morning, it took 3 hours to charge all the way, and now it's stuck on 99% full, 0:00 till completely charged, and I'm getting an error when I click on the battery in the menu bar that says "Service Battery". When I click on the error, it tells me that it may not be functioning properly and to take it to an authorized apple service retailer. Before I waste 2 hours by going to the Apple store and back, has anyone else had this problem, and is there a way to fix it without having it looked at?
I get the whole part about that I set my laptop to go to sleep in 5 minutes, and if I close the lid it'll go to sleep, and the little light at the bottom starts to pulse, etc. But in sleep mode, my battery seems to drain extremely fast!
For my old Gateway M275 laptop while in sleep mode, it would probably lose about 5-7% of it's battery in a day's duration. With my MacBook Air, I just came back to it tonight after a day's worth of sleeping, and my battery was down to 16% from 29%. And to check, it was indeed sleeping!
If you look at apple's battery life page it states the MBA battery is removable, I thought it wasn't supposed to be?Battery Lifespan For Apple notebooks with removable batteries ? such as the MacBook, MacBook Air, and 15-inch MacBook Pro ? a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.
I have an early 2008 non-unibody MacBook Pro. For about a year now, the status of the battery has been "replace soon." I was still getting a pretty good amount of time off of one charge so I wasn't too worried. This past Saturday morning, I woke up, checked the battery indicator lights on my computer (it had been sleeping since the day before) and it said it had about 60% percent so I opened it. I was on the Internet for about 10 minutes before it shut off without warning.
It wouldn't turn back on when I pressed the power button, so I plugged it in and it turned back on. When I checked, the battery status was "replace now." After using it, I turned it back off and left for NYC for the weekend and didn't bring it with me. When I got home last night, I plugged it in and tried turning it on with no luck. The battery indicator light was flashing one light, so I just assumed it would need to charge for a bit before it would turn back on. After about two hours, when I went to bed, it still was flashing just one light. I kept it plugged in over night, and this morning when I checked it, the battery indicator lights showed that it was fully charged, but it still wouldn't turn on. I still kept it plugged in throughout the day just in case, but it still won't turn on even though all the lights are lit. Is the battery just showing me false information, or should I be worried about more than just the battery?
purchased a macbook Unibody back in October 2008 when they were released and use it heavily. The battery no longer holds a nice long charge - I get about 2 to 2.5 hours out of a full charge.
The battery has 149 cycles on it, which is obviously high (and correct, I use the hell out of it). With it still being in warranty, is it worth pursuing a replacement battery? Will Apple tell me to go take a hike with the high cycle counts?
i just ordered a late 2008 macbook pro 15 with the dual GPUs (9400m and 9600m GT) and I'm a little worried about the battery life.
-What can I expect if just doing normal every day stuff (web surfing mostly?)
-does watching a movie off of the hard disk use less battery than watching it off a DVD? Is there a big difference?
I'm not a big gamer but would like to have the horsepower to play a game should one come out that I want. I'm also not a big traveler so battery times are only of average importance.
Basically, I'm asking if I made a good purchase considering I have only average concerns for both battery and game performance. They had the new 7 hour battery 15" macbook pro for the same price but it doesn't have the dual GPUs.
been using my older MBP with windows 7 for a while and have never notice oddies with the battery until now. Then recently after replacing the failed HD and re-installing Snow Leopard on my 2007 MBP, the battery panel is telling me "Service Battery"; it's battery health according to coconutBattery is fair for it's age (50%).
the unit (battery) has been replaced previously due to being considered 'under performing'. Is Snow Leopard trying to encurate it's users to replace the battery more frequently? If not, does anyone know why this appears? I'm at lost, since it appears to work fine, if not charging completely.
I'm not sure if this is SL related, but I get the service battery warning when I click on the battery status. iStat reports it at 62% health. Rev B 1.6 just 6months old. Should I bring it to apple or is it just a bug of SL?
I have a MacbookPro mid 2009 and have some problems with my battery. This morning I noticed that the battery was empty through it was supposed to be in sleep mode during the night. My battery has 97 cycles and has 99% of its original capacity. What could be the cause of this problem ?
I just want to make sure nothing else is wrong with my Macbook..have never replaced the battery in 3+ years...Always says not charging and once the magsafe is removed Pro shuts off...is completely dead battery the only problem..?
Battery Information:

So, I randomly clicked on my battery and noticed this "Service Battery" message. I had never seen it before. Obviously, this isn't a good thing. My Mac is 3 and a half years old so I'm not surprised this message poped up. So, I opened Coconut Battery and noticed my current battery capacity is at 65%. Even though charger says it's green, my battery isn't even charging. Should I make an appointment with Apple? My AppleCare expired so i'll have to buy a new battery when the time comes. I'm sure they're not cheap, either.
Apple Macbook Air late 2010, has been giving me poor battery performance even after replacing the battery under warranty. I am unable to find a solution, even the local apple service provider seems confused. Should I go for a replacement?My Macbook Air runs on the OSX 10.7.3 with all updates as on date. I use only softwares such as Microsoft Office for mac, Safari, Mail, iChat, iTunes regularly.
I calibrated my MacBook Pro battery and then noticed that the battery life seemed slightly shorter after that. I calibrated it according to this: [URL]
Just wondering if I have done anything wrong... Â
One more question... What do they mean by "At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep." Does it mean that I have to use the computer until it just shuts down or should I shut it down once the "Low Battery" warning pops up?
