MacBook Pro :: Late 2008 15 Battery Life - Watching Movie From Hard Disk Use Less Battery Than DVD?
Nov 11, 2009
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'm running a late 2008 Macbook Pro with OS 10.6.4. The battery life is terrible. Like, in the hour and fifteen minute range on a full charge. I've tried turning everything off, wifi, bluetooth, screen brightness down and turned off the keyboard backlights. If I have no applications running, it will sometimes estimate a maximum of about two hours, but never actually give me more than about an hour and a half--if all I'm doing is surfing the net.
About three months ago I replaced the internal drive with a Hitatchi 500gb drive of the same RPM as the original (5400rpm). That's the only major modification to the machine I've made and the battery life was already a problem from starters. Does it sound like there's something wrong with the battery, or is it more likely there's something else causing problems?

I know - or think I recall - that there was a user's tips article on maximizing battery life. When I'm outdoors with my MBP, I always have Photoshop CS6, InDesign CS6, Illustrator CS6, Acrobat Pro X, Parallels Desktop, MS Word and maybe a few 'little' apps running. I need these to get my projects done. I can usually get about 3 1/2 hours out of my battery but if I could get 5, I'd be happy.
Can anyone point me in the right direction for the most current (at least 2011) user tip on the topic?

I have a late 2008 MacBook Pro running Snow Leopard. and lately whenever i been running on battery, the computer has been randomly powering off. as it it losing all power, but it doesn't seem to matter what level the battery is at. but once i plug the AC adapter it, i do not have any kind of problem. i guess it could just be a dead battery.

It seems like I'm always having to charge the battery. I was just wondering how many hours should I be getting from a fully charged battery.

When I close the lid on my MacBook Pro (Late 2008), the battery drains almost completely over a night or so! Very odd. Anyone else dealing with this? I reset the PRAM already.

I have a late 2009, white unibody MacBook which is 7 months old, and I have been noticing that the battery life is getting less and less, and am rather confused.I reset the SMC as per Apple instructions, and then followed the battery calibrating guide to the letter from apple.com, and tonight it seems to have lasted... 3.5 hrs! Hardly the quoted 7 hours that Apple spec, and I am simply doing light web browsing, nothing else.Am I doing something wrong? The machine sits connected to magsafe 90% of the time, but I cannot envisage that would cause any problem, as it knows when it is charged, so afaik no more current can get to the battery to damage it

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?

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.

I am desperately waiting on the MacBook Pro refresh. I plan on buying my first MBP, a major upgrade from my grandma's iBook G4 I am currently using. I had a question about hard drive speed. I know that 7200RPM is quite a bit faster than 5400RPM, but what about battery life. I need it to get me through a day of school, 4-8 hours. My question to you is: would it be worth the extra $50 or so to upgrade to a 7200RPM HD, and what would the effects on battery life be? In your own experiences with current MBPs. I've thought about going with a SSD, but that might end up being too much, since I'm already paying quite a bit.

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

My 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 have this problem a wile now. When I play music (or watch a movie) I can hear there is something wrong with my sound output. It's hard to describe, but is is like someone is playing with an equalizer. The high pitch sounds (voices) are constantly changing in volume. maybe the basses to, but its hard to hear that. BUT, the strange thing is, when I play something in windows (parallels) it is much better... The bass is here more dimmed for some reason.

I 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.

I 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?

I 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 notice that while streaming a movie, watching a dvd or playing a game my hard drive fan is so loud, its annoying. I have a 2008 White Macbook and i replaced the stock hard drive with a western digital 5400rpm 320gb and I only have 1gig of ram. I have no problem replacing the hard drive for a 7200 but i just need to know if its worth it. If i were to upgrade the ram to 2gigs would that solve the problem? Is it possible to install a 500gig drive into the white macbooks?

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.

Would 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.

Im 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?
