MacBook Pro :: Lion Related Slowness - Startup Time Increased / Battery Life Low
Feb 12, 2012
Ever since I upgraded my Macbook Pro (mid 2009) dual core from Snow Leopard to Lion, the start up time has increased significantly, and the battery life seems to be lower than it has ever been. It has been several months since I upgraded so indexing is not an issue. What should I do, and how can I get back my missing battery life that Lion took away? And how can I make my reboot and startup time faster.

I've got an early 2008 Macbook Pro and, recently, I've noticed that the fan (fans?) begins running from the moment the computer is powered-up. iStat tells me that both fans are running at about 2000 rpms, though I only hear a slight whoosing noise from the left side. I don't remember the fan running constantly, and I have noticed that my battery life seems worse than normal recently. Is this normal, and something I just haven't noticed until recently?

I've had my unibody 2.0 since November. It's always said 5 hours or so when i open it up fully charged. This week it's started fluctuating wildy. While typing this post it's gone from 3 hours 23 mins to 4 hours and five mins....it started at 2 hours....now it's up to 4...very odd. Any ideas on why this has started happening all of the sudden?

Just bought a new MBP Unibody and I'm loving it so far. My friend has the one with the single graphics card and he's claiming 6-7 hours of battery life on a single charge with the screen lit a little under half. I set mine the same way and I don't get as much battery life. I have the one with the dual video cards. Is that going to cause the battery to drain faster and if so, can I disable the second video card when I'm not doing intense graphics processing?

I recently bought a 12" Powerbook G4 from ebay, and am curious to know about the battery capacity. It came with the original Apple battery, and it usually powers off before the battery is at a low percentage power. So I have installed Coconut Battery and Battery Health Monitor to check how the battery is doing.
Both say that the battery capacity is now 6393mAh, and the original capacity was 4200mAh. As such, they say the battery health is 100%. How is this possible? How can battery capacity increase? I presume this is wrong. Is there any way to correct this? The powerbook, according to the apps, is 65 months old (it is an original 867MHz model). Both battery apps also say the battery has gone through 59 charge cycles.

After updating to iTunes 10.1.1 the app did not start at first so I went to download it and installed it manually. iTunes works but my boot time went from ~2 wheel turns at the boot screen to ~16. Installed the new airport update, as well. I repaired the permissions and did a PRAM reset.

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?

I installed the new Lion software without any problems, everything runs great. But my battery life has dropped from 8 hours down to 2 hours.I am constantly having to charge the lap top to make it usable - I may have well purchased a desktop machine if I can only get two hours without charge?

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'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

Normally when I shut power off my MacBook Pro, it takes about 4-5 seconds and then its off. Since I installed VMware Fusion yesterday, it takes about 1 minute to power off. What is going on? I read somewhere that when you quit a virtual machine you need to choose "kill all" to stop any background processes. How do I do this or is this just normal.

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

After a catastrophic HD crash I bought a small 250GB external hard-drive an started to use Time machine. Since my Mac was freshly formatted, I tend to keep it tidy and clean and keep good track of what comes in. I noticed my time machine backing up 15 GB of data which allegedly would have been added within two days. I could absolutely not trace this on my computer nor when I compared current folder contents with the most recent backup. Downloads, Apps., System are all excluded from my time-machine and couldn't represent such a dramatic data increase on my separate HD.

Purchased this notebook used, but very nicely cared for, excellent condition. I ran the Apple Hardware Test and everything passed including the logic board.
The battery has 500+cycles. The problem is laptop shuts down at 50% or less of battery. Clock is wrong at startup but is correct a few seconds later.
Runs forever and very nicely on ac power.

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 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?

would like to say that is my first mac and I am loving it. I've got the new 13" 1.86ghz 128gb and the upgraded ram 4gb. Now I've fully charged it and left it on a further 2 hours or so, following the instructions for calibrating the battery. Now that I'm using the macbook, I'm noticing the battery going down fairly quick, already at 88% after 30mins of use. Is it supposed to go down this quick?

Looking into getting a SSD 128GB for my 2009 uMB but I am wondering if that helps extend your battery life because I am getting 3.5 to 4 Hours on a single charge now. I just wonder if I can get more than 5 hours out of the battery with an SSD, then I can use the external drive for everything else but OS and Applications.

I have become incredibly confused and frustrated as to why my MBP battery life has gone down the tube. I've had it around release date with minimal cycles. I've tried:
1. brightness reduction
2. turning off wifi/bluetooth
3. items that auto log when computer is turned on where removed (such as adobe updater)
