MacBook Pro :: Battery Time - Getting 2 Hours With Full Charge

Jun 27, 2009

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.

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.

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?

MacBook Pro :: Battery Sometimes Won't Charge After Being Unplugged For A Few Hours?

Mar 19, 2012

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?

MacBook :: Aluminum Battery Takes Almost 7 Hours To Charge?

May 7, 2009

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?

MacBook Pro :: Replacement Battery Only Holding 2 Hours Of Charge?

Apr 8, 2012

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?

MacBook Pro, Mac OS X (10.6.8)

MacBook Pro :: Full Charge Capacity Of New Mbp Battery?

May 23, 2010

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?

MacBook :: 2.1 Won't Hold Charge But Battery Indicator Is Full

Jun 7, 2012

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.

MacBook Pro :: Unable To Charge Full Battery / Charging Stops At 70%

Dec 19, 2010

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...

PowerPC :: PB G4 1.67 - 15" Battery Power - Green Light Never Came On To Indicate Full Charge

Sep 17, 2010

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.
