MacBook Pro :: Low Performance After Some Hours Of Use
Dec 5, 2014
i recently noticed that my MacBoo Pro was with low performance after some hours of use.I try to monitor what might be causing it. What i note was:After restart (or fresh start), my computer was ok;I use applications like adobe Lightroom and VMWare Fusion;Then I star feeling like Safari was too slow to open pages - I thought it was the internet link first, but even local webpages are slow. I notice that when a click to close a tab, it take almost 2 sec to do it. The same when click to open any link on that page.I start the activity monitor, but my proc usage are low. Then, I notice the (weird) memory usage: Take a look at "memory used". I closed all applications before take this screenshot. i've trying to identify what is consuming this memory, but.. no success.

I recently purchased my Macbook and I noticed that the battery power is jumping at least an hour every time I check how much battery power it has left. I wanted to know if this was normal.

I have a MacBook. It's 4 or 5 years old. I downloaded an older version of Handbrake so I could transfer some of my dvds to my Ipod Touch. The newest version didn't work. The first step didn't take too long, but the second step (I think it was Rip) is another story. When I clicked the Rip button, it said that it would take more than 25 hours to Rip. I left it running for 5 hours and it was not even one quarter done. Am I doing something wrong? The dvd is only an hour long.

I've just bought this brand new macbook pro 2 weeks ago and it only lasts this long. I'm not doing anything besides firefox and microsoft word. Why is it so short? Can I get a replacement since it obviously is a manufacturing defect?

I bought the new macbook pro 3 days ago--not the one with the retina display; I dont need that--and was hoping to get close to 7 hours of battery life. After 3 days of use, my battery now has an average life of less than 4 hours.
Should I contact Apple about it? I know that the add says battery time may vary, but by 3 hours?

I've got a 4 month old Macbook Aluminum 2.4 ghz. I was getting great battery life for the first couple of months. But I'm now getting 3:10 with screen half light, and wifi on, bt off, doing a bit of downloading, etc. I've recalibrated the battery a number of times. According to activity monitor my cpu is hovering under 10% when I'm doing my battery test. This is at least 2 hours less than I was originally getting. Coconut Battery tells me that the original capacity was 4100, but its currently at 4052. Battery load-cycles are at 97 and it says the Mac is 5 months old. Should I take it in to the Apple store under AppleCare?

My four and a half pound MacBook, even with wonderful battery life is too much to bear. So is the thought of using Windows 98. Otherwise I'd buy a Netbook.
How many hours of word processing can I expect from the latest version of the MBA?

I have the 13" MacBook Pro with the beefiest processor and a 500GB HDD. When I bought the machine, I quizzed the guy at the store about a couple of things. In particular I asked about the battery life. He told me apple claims that this machine should have 7 hours of battery life when doing light tasks, but that he personally was able to squeeze out over 8 hours of battery life with simple web browsing.
My problem is that I can barely get 3,5 hours worth of batterylife out of the machine before it gives up the ghost. And this is with the backlight on the display turned down to 1/3 of full brightness. And all I'm doing is browsing text webpages with no flash. Is this normal? Or have I simply overlooked some basic power option that I need to toggle?

I turned my computer on at 4:05pm. I made sure it was charged to 100% before I unplugged the power supply. It is now 5:15pm and my battery is already at 14%.The ONLY programs I have had running are:- iTunes - Safari - Firefox (not being used, just on)Other things to note:- Energy Saver set to: "Better battery life" instead of "Higher Performance". - Display brightness set at 13/16I'm getting less than 1.5 hours of battery life while just searching the internet and listing to music.

During startup, my Macbook Air 2011 sits at the grey screen with Apple logo and spinning gear for at least an hour before prompting me to log in.In the last few weeks, the time it took to get past the grey screen increase to roughly 10 min, but in the last couple of days its grown even longer. My Macbook Air has also often failed to resume from sleep and required a reboot.

I've purchased my first MacBook air. This is the second crash it had in two days. The first one occured when I was watching a youtube video and the second one happened while closing Chrome (while watching a youtube video). Should I go back to the store or can I fix this myself? [code]

I just bought a new 13" MacBook Pro, and the first time I charged it the battery lasted 7 hours. For my second and third charges, the battery at full charge says it will only last 2.5 hours. My screen is at a low brightness level, and I don't have anything strenuous running--only Safari or Mail...

Are you all experiencing about the same battery time as me?
People I know with a 2010 13" MBP doing about the same activities as me are experiencing much longer battery time, around 7 hours.

So my Macbook Air 11" was plugged in all night, was using it this morning plugged in. Battery was at 100%. Unplugged it but left it closed all day (7am to 4pm)opened up up and battery indicator says 9% is gone and it's busy charging away now. I have noticed this over a few days now.
Thats a little harsh no? It's supposed to last 30 days or whatever when its sleeping but it won't last a week at this rate.

On a full charge at 99% while surfing on firefox using airport with the brightness turned down to the last light and the keypad light turned all the way down it says there's around 4 hours left and as of this typing im at 87% with 3:37 left. Ok this is no where near the battery life im expecting as a matter of fact this is an average battery life and a main reason why I bought the macbook pro was the "8 hours" of battery life. Is the time not consistent with the percentage or am i really running that low on battery life? What gives? Could it be that im splitting harddrives with boot camp? Im not running it right now but i have vista installed.

I just got this 13-inch MacBook Pro on Friday. Everything I've read absolutely raves about the battery life. However, I only get about 2 hours per charge; I got waaaaay longer on my year-old MacBook I just sold. I have Firefox and Pages running, but nothing else. Am I doing something wrong?

I'm restoring my data (roughly 78GB) because, when trying to partition my disk, I got the annoying "large files cannot be moved blah blah" error. So I backed up (which took almost 5 hours), formatted, and am now currently restoring, at an estimated time of 18-21 hours (it fluctuates, even said 1 day 5 hours at one point). I'm using an old LaCie 120 External, a few years old, but at the least it should be 5400 RPM. Is there a problem that's causing it to take this long, or is this normal? Oh, I forgot to list specs. On the 2.4 ghz Core 2 Duo, 2GB ram, 8600m GT model.

I just got my new 17" i7 MBP. Installed Intel 80gig SSD for boot and started installing OSX from supplied installer. Installation took over 2 hours with the optical drive making only slight noises every few seconds, not sounding anything like it should. Eventually it installed and everything seems fine and really snappy. Replaced superdrive with newmodus tray and hitachi 500gb drive.
Started installing Final Cut Studio 3. Pointed all audio and extra content to 500 gig drive. Installation of each disc is taking 2+ hours from an external CD/DVD drive hooked up usb 2 for one disk, then tried firewire for the next. Still really slow. What gives? Can't figure this one out. Does it have anything to do with the SSD?

My Air (2010, OS X) takes 2 hrs to boot. No peripherals, 4 GB unused. After booting the cursor is active but any action (eg opening app) results into beachball. Restart takes another 2hrs.

I've tried two brand new adapters and neither work after my MBP is unplugged for a few hours and then plugged back in. Eventually it'll work again, but occasionally it doesn't acknowledge the power source. Will AppleCare cover this?

I have got a macbook pro with 2.2 ghz AMD 6750 graphics card. Its around 8 months old. The battery used to last around 4 hours but recently I get around only 2 hours. I have tried to change settings in energy saver to improve battery life but its still the same. I ve noticed that when it shows AMD graphics in about my mac, it takes more battery life. So, I guess its using more battery at that time. Ive read it switches automatically depending on the task but is there anyway to change it in settings?
Also, how is it possible to get the best possible battery life? Should I keep charging and discharging it every now and then.? Currently I unplug the adapter as soon as it gets fully charged and the battery last for over 2 hours (surfing, listening to music, half an hour of video).
