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?

after upgrade to lion, 2010 battery life dropped from 8-9 hours to 3-4 hours?

Battery life on my MacBook Air (1.86/SSD) has dropped to less than two hours (for casual web browsing).When new, I got more than 4 hours on a full charge.Also, the battery meter seems to be way off.The machine shuts off with the meter showing 40% remaining. I've tried several full charge - discharge cycles.System information shows battery health to be good.
View 7 Replies View RelatedI used to be able to use my macbook pro all day at school, from 8:50 till 16:00 without charging it at all, no problem. Suddenly however, over the easter holidays (about 3 weeks) It dropped significantly, barely managing 2 hours. During the holidays it was almost constantly plugged in to the mains, but this hasn't caused problems before, I've had it about 18 months and had longer holidays with no change. A few months ago I upgraded my ram from 4gb to 8, but it didn't seem to affect it at the time. (I know it still says 4gb in my info but the forums won't let me change that for some reason)

View 18 Replies View RelatedI 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.
View 24 Replies View RelatedI 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?

View 4 Replies View RelatedApple 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.

My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged. When I put the brand new battery on the lap top, the computer shuts down halfway through boot up.

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?

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 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 12 Replies View RelatedI'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
has that happened to anyone? and if so, did apple replace the batt for you?
View 20 Replies View RelatedI bought a MacBook in late October, and it was my first, so I'm pretty new to Macs. Love it so far!
But anyway, here's my question -- my battery capacity has been at over 100% since I bought it, according to coconutBattery, and yesterday it dropped to 98%. I decided to calibrate it because I hadn't done that yet. So I let it put itself to sleep and left it that way overnight, then recharged this morning. When I first plugged it in, the capacity was at 99%. Now a few hours later, it's at 95%.
So, is it more likely that my capacity has been 95% for awhile and the calibration just helped synchronize the capacity display with the actual capacity, or did I really lose 5% in two days?!
I'm trying not to be totally crazy obsessive about this, but I really need a good battery life, and I want to keep this one going for as long as possible.
Last night I calibrated my battery. Let it fully charge for 2hrs, took it off the charger, turned up the screen brightness and keyboard backlight all the way, then proceeded to run the battery down watching videos and whatnot. It went to sleep and I went to bed to let it sit for 5 or more hours. Woke up, charged it up, turned it on and noticed that I went from 97% to 87% (coconut battery says 86%) and I only have 54 cycles. Should I go to the genius bar or something? Or try re-calibrating the battery? Did I do something wrong when I did it? Does it matter how long it takes to run down the battery after it's fully charged?
View 10 Replies View RelatedSo 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 ...
So I charged my battery to 100% and then unplugged it from the charger. Thats when the battery dipped to 97% instantaneously. It was very odd and somewhat scary. I just bought this MBP 2 days ago! Anything i might be missing? Is it supposed to do that?
