MacBook Pro :: Getting Around 4 Hours On A Full Charge While Using The Internet?
Jun 24, 2009
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.

Late 2008 refurb Macbook Pro, 2.53ghz, Windows 7 RC (therefore forced to use the 9600 at all times). According to this report, the MBP got around 3&1/2hrs of run time with a dimmed screen and watching videos. From a full charge, I start browsing the internet (no videos at all), and my battery reading read as follows
91% 1hr, 16mins
90% 1hr, 20mins
89% 1hr, 24mins
87% 1hr, 23mins
Not only were the readings all over the place, but even from a full near charge I wasn't even getting an estimate of 2hrs, while Apple advertised 4 for the late 2008 model, and the review I linked to says they got 3&1/2. Do I have a bad battery, or does simply running the 9600 reduce the battery life by such a drastic amount? I have already calibrated my battery following the guide on the Apple website.

my Macbook that is in my signature is currently saying that it will take ten hours to charge (See Pic) after charging for the first time in two weeks after coming back from a camp and I'm not sure what to do.

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 am thinking of using a solar panel setup to charge all of me and my family's MacBook's, iPhones, iPod, and iPads, and if anyone know the approximate number of watt-hours it takes to fully charge each of those you would make me very happy

I just ran my battery down last night and left it over night to re-calibrate. I plugged it back in at 11am and it's now 5pm and I'm still showing a half hour to finish the charge. That's nearly 7 hours to fully charge the battery. Madness. Is this normal or is this worthy of a visit to the Apple Store?

I took my macbook pro to get a new battery at the genius bar after it stopped holding charge, turned off unexpectedly, and would get really hot. After getting the battery, I calibrated it right away by draining the battery, letting it sit for five hours, and then charging it. The new battery only holds 2 hours at 100% charge. Is the replacement a dud or something else wrong?

i charge my macbook full and it only ever lasts me up to 2 hours (never more) lately. i got my pro in september and noticed these problems a couple weks ago. the battery also runs loudly and the entire time my mac is on and my mac heats up real quick and hot. should i just bring it in to get it checked out?
i also only ever have a few applications running, the same ones ive always had running. theres no reason i should currently have 1:53 on my mac left at 90% battery.

I noticed that the full charge capacity for my mac varies. On first charge it indicated 6580mAh, then on second charge 6685mAh(which the software indicated that I was able to fully charge to this capacity), then now after I unplugged it for a bit it now says the full charge capacity is 6850mAh. I'm planning to calibrate my battery on this discharge.

I received my new 15", i7, 128gb ssd, 8gb ram macbook pro on april 19th. I love it and have no problems. Have any of you guys noticed that the full charge battery capacity, which is found under system profiler-power, varies often. When I first got the macbook pro the full charge capacity of the battery was around 6830. Now with each charge it seems to go down slowly. At first it jumped from 6800 to 6600 and now stays at around 6520. Is this normal?

"To allow the adapter to recharge the battery to 100%, simply allow the charge to drop below 93%. The adapter will automatically recharge the battery to 100%."

what is the default Full Charge Capacity (mAh) of MBPr 13" battery when it's new? Recently I noticed that on my device it shows only 6069 mAh, though my device is barely a year old and has only 41 charge cycles (of 1000).

For the past three hours (during which I've been doing some light web surfing (no Flash), text editing, and FTPing, with the screen on low brightness -- definitely not energy-intensive stuff -- my battery indicator has been showing it charging with 22 min remaining. Why the heck would that happen?

I have a week old 11.6" MacBook Air. The battery has 3 cycles. However, using Coconut battery the battery capacity is showing 96% fully charged. Would that be unusual after 3 cycles?

My wife's Macbook 2.1 is acting strangely. The Battery indicator led's are full (green) the charger led is also green and the software shows 100% battery is charged. After a couple of seconds after disconnecting the charger it switches off. I've tried resetting the SMC and this allowed a full nights use without the charger but on the next day it went back to only holding for a couple of seconds. I don't want to have to reset the SMC every day. It's running on 10.5.8 and is all up to date.

Then I can reboot work for half an hour until battery is like 50% then it shuts off again... then I can reboot again and work for some more time. I've checked with coconut battery and when the computer stops at 70% I still have like 1700 mAh...I've reset PRAM, power management, etc...
Of course my battery is old, but it should work until 00%... not stop at 70%. Before I spend like 100$ (that is what a macbook pro battery costs here in Mexico) I'm willing to try anything...

I have a Week 01 MacBook Air, and I just started to notice that my MBA has not been performing its best since I bought it.
This morning I at 0745am, but now its 0831 and my battery is now at 53%; is there something wrong? I took a stopwatch and averaged it at about 53-55 seconds where the battery will drop 1%.
According to coconut battery, current battery capacity is 4670 and original battery capacity is 5090, and the system profiler says that I'm at 31 charge cycles. And YES, i've reset the PRAM, PMU/SMC, and calibrated my battery

I bought a 3rd party battery for my MBP. I put it in and after cycling the battery i noticed that the full charge capacity was only 3990mAh (supposed to be 5500mAh). I returned the battery today and got and an upgraded replacement. this shows the full charge capacity at 4995mAh (supposed to be 5600mAh).
is this normal. Do I just need to give it some time or is it something with the batteries.

Why is my Mac not at 100% battery after having it powered off and plugged in charging all night? As long as my charger is plugged in shouldn't it be at 100%? I never unplug it. It shows it is charging but stays at a constant 98%.

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.

Basically I'm having issues with my newly acquired Powerbook G4. When i bought it the battery was not working at all so have now installed a new replacememnnt battery which works fine but having some slight issues. So...
First time I charged it, it reached 100% but green light never came on to indicate full charge. When I run the PB off the battery it gets to 20% and it shuts down without any warning it's low on battery (trying to switch it on after this is impossible, it clearly has no life) After the above I connect the power lead and start up the computer, the battery indicator starts charging from 20% onwards. Something fishy definitely going on and I have no idea what it could be, I calibrated the battery but it has always cut off at 20% since first charge/discharge.

I have a 1.67 GHz Powerbook G4. This morning it was fine. When I got home from work, it decided that it suddenly no longer wants to stay on when not plugged in. The battery is showing a full charge. The light on the plug is green. But the second I unplug the cord from the laptop, the entire thing shuts down.
