I have the screen as dim as it can get. All I'm on is Airport with nothing else really going on and my battery life is only about 3 hours.
It used to be somewhere like 7 hours when I did this.... any idea if something could be wrong?
Coconut says I have 96% capacity left...
I know that the 13" MacBook Pro supposedly gets '7-hour battery' life, but does it really? If any of you have the 13" MBP, how much battery life do you get with yours?
View 10 Replies View RelatedI contacted Apple, who got me to a 'battery specialist,' who asked me to send in my system profile. A new battery was authorized, based on the fact that my battery didn't seem to be reaching capacity (or something to that effect).
View 2 Replies View RelatedMy MacBook pro's battery life has really gone down hill. I bought a battery in September '09 and rarely used it. Recently I put it in because my original battery supposidly does not hold a charge. Now it only gets a hour when last week it got 4! What happened? What is wrong with my computer?

I noticed the fan was running the whole time. I didn't realize watching a video online would cause the processor to heat up so much!!
I checked the CPU utilization, and definitely Safari was cranking it up there...
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.
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...
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?

My new MBP has 5 hours of battery when doing light web browsing at medium brightness. Only 2-3 hours when playing low res youtube clips, and 6:45 hours with all apps and wifi turned off and screen brightness at minimum.
When I first turned on the MBP I charged it to 100% and then discharged it down to 0. Is this battery life normal? What happened to 8-9 hours with wifi and web browsing? I can't even get 7 hours with everything off!
So from what I understand my 2 month old MBP is supposed to have a 10 hour battery which is a stretch! I would say 5 hour battery at best, which is great and I am not complaining but 10 hour eh? Is that while the computer is sleeping?

I have a 13" 2.4 GHZ white macbook that I bought in march of 2008. About 4 months ago I all of the sudden started having problems with battery life. It was very abrupt. I used to be able to take my macbook and sit through 3 classes or more with no trouble in regards to batter life. Then suddenly the battery would drain within a few hours. It has remained that way since.
I've spent the last month or so looking around forums and other places to try and find someone with a similar problem and possible solutions. As a result I've discovered that my situation seams to be somewhat unique.
Using cocoanut battery I tested my battery's capacity and it remains at a solid 98%. How can my battery still be at 98% capacity and have such a short battery life? I also seam to be losing charge while my macbook is closed. How and why does that happen? If I leave my macbook closed for a day or two it can lose up to 25% charge just sitting there!
I've tried loads of things including turning off unnecessary things such as sharing and bluetooth and calibrating my battery, all with no avail.
What is going on?? My battery is too old to be eligable for a recal and I'm not paying $30 just to have a phone conversation with a "Genius". If anyone has any idea what's going on and any possible advice, I would greatly appreciate it.
I am getting a very short battery life out of my "New" A1261 battery - we're talking 2.5 hours tops. I've recycled it a few times, but this is no where near the "7" hours that is quoted.

MacBook Pro (15-inch Late 2008), Mac OS X (10.6.8)
I haven't been able to find out an answer for this. I bought a MB467LL/A model Macbook (2.4ghz previous unibody version that became the Macbook pro). Local store had them on closeout and it was a hot deal. Anyway, it was brand new and had a 0% battery when I brought it home. It's been about 12 hours and still isn't quite charged fully. Almost though.
Is this normal for a brand new battery? I can't imagine it usually takes 12 hours to fully charge the battery. I've never had a computer ship with a dead battery before so I'm wondering if it was bad or simply that's how they come now a days.
Could you somehow put the 8-hour battery of recent macbook models, into the macbook book late 2008 model?

This morning I at 0745am, but now its 0831 and my battery is now at 53%; is there something wrong? I took a stopwatch and averaged it at about 53-55 seconds where the battery will drop 1%.
According to coconut battery, current battery capacity is 4670 and original battery capacity is 5090, and the system profiler says that I'm at 31 charge cycles. And YES, i've reset the PRAM, PMU/SMC, and calibrated my battery
I've had this MBP for just over 8 months now, I'd intially purchased one in november, but the audio out used to give a crackle sound so they replaced the laptop. Moving on to the point - in the last week or so, I've noticed the MBP suddenly seems to get very hot and the fans turn on and thus suddenly becomes very noisy. I was using it on the bed so could appreciate that I may have been blocking the vents, but I've had it on a stand the past couple of days and it still seems to do it for no particular reason. The charger usually always gets ridiculously hot, but the MBP used to stay relatively cool, now the MBP gets hot independently of whether its being charged or not. Moreover, my battery life has gone from what used to last 4 hours, to around 2.25.
Cocunut battery gave the following stats:
Current Battery capacity: 4483mAh
Load Cycles: 222
Age: 8 months
I have just bought a MacBook. I have downloaded the Battery Health Monitor and it says obviously that my current capacity is at 100%, with 5,791 mAh. I would like to know how many hours does this value correspond to, because it has certainly not been the highly announced 10 hours battery life
View 6 Replies View RelatedSo my MBP 13" 2.26ghz worked up until the firmware update was installed, and then everything froze up and it took about 15 minutes to boot up, 5 minutes to shut down. So i called apple, and after a 1 hour phone call, they told me that i could get it replaced. I live an hours drive from the nearest apple store, and will have to drive up there to get it replaced, do you think i could ask for some kind of compensation for my problems, and having to drive 4 hours (2 to buy it the first time, 2 more to get it replace) to take care of the problem.
Do you think I could ask for the 2.53ghz model, or an apple/itunes gift card. or Should i even ask for anything, i mean i paid 1200 for this computer, and after 3 hours of owning it is not useable, and now i have to spend all this time trying to get it replaced.
My two year old macbook pro battery life is getting shorter after recharging. I only get about 40 minutes on a full charge when it used to be 3 hrs. Is it time to replace the battery?

View 1 Replies View RelatedI am interested in getting a refurbished Macbook Air. I was looking at the following two models:
Macbook Air Rev B., 1.86 GHz, 2GB RAM, 128 GB SSD for $1349 OR
Macbook Air Rev C., 2.13 GHz, 2GB RAM, 128 GB SSD for $1549
Other than the processor difference of 0.27 GHz, and based on reading the technical specs of each system, I don't see any difference between the two machines. The one piece of information that I couldn't find was the advertised battery life for the Rev. B unit. The Rev. C unit is supposedly rated for 5 hours of wireless productivity. Is the same battery used in the Rev B also or is the battery of lower WHr?
My needs are pretty simple - I would like to get the Air as a small and portable, easy to carry machine for rounds and writing up patient notes, consult notes, etc. It will not be my primary machine, but hopefully a worthy road-warrior. I will be using Windows for the clinical electronic medical record application, but other than that, all other use will be on Mac OS X. Based on this, would you recommend going with the Rev B or Rev C. Money is tight, and this will be a gift from one of my mentors, but I do want to get the biggest bang for the buck. If the only difference between the two machines is processor speed, I can't justify spending 200$ extra just for a 0.27 GHz gain.
I have a 2007 White Macbook 2.4 Intel Core 2 Duo Laptop. I purchased it in June 2007 and this is my current battery health. Check the picture below, It's pretty amazing and I don't know how I did it. I'm on my computer almost everyday. Any idead on what I did to get such great battery life after three years? I know people with newer MacBook Pros that have terrible battery life after a year and a half.
View 1 Replies View RelatedI bought a 1st Gen Macbook Air in March of this year and I recently have noticed that my battery is not lasting as long as it should, so I checked iStat and it said that my battery life is at 86%. I also have a 12 inch powerbook G4 that still has the same battery it came with and the battery life is also 86% and it is more than five years old. Is this normal for the Macbook Air or should I take it into Apple?
View 10 Replies View RelatedI have a quick question about the battery in early 2008 MBP. The laptop is 13 months old, with 273 load cycles, and it is already down to 72% of original capacity. I've read that it should still have 80% at 300 cycles. Is this normal, or is the battery dying faster than it should? I don't suppose there's anything I can do short of buying a new battery right??
I got my MacBook Pro on the 1st of September and I'm a bit worried about the battery life. At the moment the screen brightness is one bar and bluetooth is off, which is how I normally have it and the battery life time estimate keeps changing quite a lot. 5 minutes ago it said 5:11 left, and since then it's changed to 7:30, 7:58 and now it's saying 6:50 and is now on 95% and 8:03. I'm not doing anything differently and I don't know why it's doing this.
View 3 Replies View RelatedWould be extremely interested in hearing about the battery life of the MacBook Air either the 13.3" or 11.6" from someone using it firsthand.
View 1 Replies View RelatedIm a little confused, is the Air Battery life that good? I've taken the following claims from the Apple website. MacBook Air - Get up to 5 hours of battery life on a single charge on the 11-inch model and up to 7 hours on the 13-inch model. 13" MacBook Pro - The new energy-efficient architecture in the 13-inch MacBook Pro gives you up to 10 hours of battery life on a single charge. I understand that Steve Jobs advised that they were using a better way to measure battery life for the Air that reflect real world usage better (WiFi Browsing I think?) so how does this compare to the MBP range? I guess the MBP battery claims were made using another older method, so any thoughts on how the Air's battery life compares to other PC's and Mac's?
