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.
I can't seem to get 3 hours of life out of this battery and I wanted to know if I was alone on this. I've drained it multiple times and my capacity is at 4829. Sure, with the screen dimmed all the way and everything turned off I can reach 4 hours, but that's not why I purchased this machine. With my screen on max, no bluetooth, and WiFi on, I struggle to get 3 hours. This is with normal web-browsing, typing in word, etc. Forget about watching a movie, because the time remaining will just drop like a rock. I don't recall what the max capacity was on these batteries. If it's 5200, then I'm already at ~93%. At what point do I go into Apple to demand a new one?
when I bought this thing, I easily got 5 hours, but two years later and 489 charge cycles (according to coconut battery) I am lucky to get 3 Solid hours of web browsing.What is the life span of these batteries, I am assuming I might just go to Apple and buy another one for $129.00 a rip off but what can I do, I will not use another brand of battery.
Apple has stopped bundling Adobe Flash on new Macs, ostensibly so users could obtain the latest, secure version themselves, but vastly increased battery life seems to be another leading reason.
According to testing performed by Chris Foresman of Ars Technica, the new MacBook Air can last for a full six hours after loading a series of webpages in Safari, but its battery performance drops down to four hours once Adobe Flash is installed and the same sites are loaded.
"Flash-based ads kept the CPU running far more than seemed necessary," Foresman wrote. Without the Flash plugin installed, websites typically display static ads in place of Flash content, erasing the need for constant processing power demanded by the Flash plugin's rendering engine.
With Flash ads consuming as much as 33 percent of the MacBook Air's battery potential, it's no wonder why Apple has demonstrated no interest in getting a version of Flash installed on its iPad, iPod touch and iPhone, all of which have much smaller batteries.
This summer, Adobe launched a public relations attack on Apple for failing to support Flash on its iOS devices, nor allowing Adobe to deliver a version of Flash for the iOS platform, nor approving apps for the iOS that were created in Adobe's Flash Professional application. Apple has backed away from refusing to approve apps created with third party tools, but has shown no interest in getting Flash content to run on its iOS.
When asked for "any updates" on the company's stance on Flash during its quarterly earnings report, chief executive Steve Jobs quipped, "flash memory? We love flash memory," before taking the next question.
Apple's removal of Adobe's Flash plugin from a default install on the new MacBook Air coincided with the company's debut of a more conservative new "wireless productivity test" it said was more in line with actual use, and better standardized for accurate comparisons between models. Being able to test the new machine without its battery being taxed by Flash ads certainly helps the company achieve better results.
The Shrinking Flash Platform
Microsoft stopped bundling Adobe Flash with the release of Windows Vista in 2007, although its motivation was likely due to the company's efforts to push its rival Silverlight plugin. However, Windows implements Flash as an ActiveX control, which means users can click on Flash placeholders within a webpage and the Flash plugin will install itself. New Mac users will have to manually download and install Flash from Adobe in order to make it available.
Apple sells far more iOS devices than Macs, and no iOS devices support runtimes for Flash content. That has had a major effect upon advertisers, publishers, website design, and online video broadcasters, who have collectively made monumental shifts away from Flash. This in turn has made Flash playback far less important on the desktop than it was just a year or two ago, although there is still important content tied to Flash.
Apple has removed Flash content from its own website, although it also has supported Adobe's efforts to add hardware acceleration to the Mac OS X version of Flash, and has approved the Skyfire plugin for iOS' Mobile Safari, which uses a gateway service to translate Flash videos into HTML5 videos that can play on Apple's devices.
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 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?
So i have the mid 2007 (i think) non unibody white macbook.
Yesterday after some normal usage i noticed the battery had only 30 minutes left even though it had 94% left, also the Service battery Now message had appeared
This was odd cause even though my mac is quite old a few days before the battery was lasting a normal 4-5 hour charge.
after leaving it charging over night after trying to recalibrate the battery(i dont think it actually ran all the way down as it lasted minutes while not on battery power even though it was 99%), resetting the pram, nvram and SMC, the battery now reports 20 hours of life left, but the "Replace now" message came on.
now obviously i would be ok with 20 hours of life left, but its had 20 hours left for 30 minutes an hasnt decreased
Ive googled and searched the forums but couldnt find an answer ...
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'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'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 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
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?
I own the newest (see my sig) macbook pro 17". i am doing nothing but web browsing with half brightness and no keyboard illumination and nothing else running with the 9400m graphic. i am only get 3 hours 25 minutes from a full charge
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...
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.
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'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).
I just bought Mac Air 11" three weeks ago. I noticed that the average standby time of the battery is only three hours. I need answer on this because it ain't normal at all.I have to recharge the battery 3-4 times in a day.
rMBP charged overnight and I woke up at 7am and disconnected it, it is 9:30am and my battery is already at 34%. What ca I do? Only running Safari although a good portion of the morning was youtube videos. Still with some YT video playbacks here and there, should it drain this quickly?
