MacBook Pro :: Late 2008 15 Battery Life - Watching Movie From Hard Disk Use Less Battery Than DVD?
Nov 11, 2009i 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.
MacBook Pro :: Battery Life Slightly Shorter After Calibrating Battery
May 4, 2012I 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?

MacBook :: Good Battery & Terrible Battery Life?
Jul 16, 2009I 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.

View 1 Replies View RelatedMacBook Pro :: Battery Getting Hot / Battery Life Reducing
Aug 10, 2009I'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

View 6 Replies View RelatedMacBook Air :: Rev B Vs Rev C Battery Life
Sep 5, 2010I 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.

Hardware :: Won't Work With Battery Life / Too Low
Sep 23, 2009i Have a 15 inch unibody MBP (the one with the 4 hour battery) and since I got it, iv realised iv never gotten close to 4 hours on it, even just with web browsing.
I tried the battery calibration thing on apples website but that didnt help at all. On a full charge if I check the battery it says I have 2:45 left, sometimes 3. thats not even close to 4 hours.
also, I can NEVER finish a movie all the way through. If im watching a movie, my battery will usually die about an hour and thirty/fourty five minutes in and I always have to plug it in to finish. does anyone else have these problems? or is this just how its supposed to be because it kinda sucks
My mac is on the more battery life setting also, and was purchased late april 09

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 1 Replies View RelatedMacBook Air :: Air's Battery Life Is Good?
Oct 21, 2010Im 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?

Nov 2, 2008I was an early adopter of the MBA 1.0 and had to return it due to all the "Rev A" issues that plague Apple machines (just look at the new MBPs and MBs). The unit I had back then had about a 2-3 hours of use (vs. Apple's claimed 5) and it took FOREVER to fully charge the battery. Not to mention the core shut downs, ridiculously loud 6200 rpm fan, excessive heat, etc. etc.
I was wondering if any early 2.0 owners could comment on battery life or charging. Have they fixed this problem? Any 1.0 owners notice less batt. life now that Apple claims 4.5 and we have the nvidia chipset?
