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.
View 3 RepliesI 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?
View 6 Replies View Relatedwhat 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).

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?

View 3 Replies View RelatedI had to delete a Yosemite partition I created on my mid 2012 macbook pro because the 16gig available filled up fast.
I check my HD and it was almost full to capacity, it shows I had 2.2 TB of photos and 1.5 TB of audio.
I don't know if this photos and music kept adding each time I sync my iphone or each time i log on to Facebook.
Anyway I would like to FREE UP THE SPACE but how, and would I need to have 3plus TB of external DH to do this, or what??????

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.

My Mac Pro never seems to get a full charge from my charger.

MacBook Pro (17-inch Early 2011), iOS 5.1.1, I always update my software
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 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.

I just got my new MBA 13" ultimate and this battery never seems to be fully charged (system shows 99% charging for over 1 hour now) and magsafe light been amber throughout the entire time. I'm worried it may be a battery problem, tried resetting SMC two times but no effect.
View 20 Replies View RelatedThen 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

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%.

When I export a QT video in Final Cut Pro, I look at iStat and my CPU usage is total around 25%, with that usage being spread evenly through the cores. Is there a way to get it to take absolute full advantage of the processors, or is it doing its best job?

Does anyone know how the ATI Radeon HD 2400 XT with 128MB compares on performance to the shared 256MB in new Minis? Also, in iMacs with an 800mhz system bus that have 667mhz ram preinstalled, will they take (and run at full capacity) 800mhz ram?

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.

I have a mac book pro...one of the older models...around 5 or 6 years old..the silver one with the silver around the screen part. Running Mac OS X 10.6.8,
2.33 GHz, 2GB ram.
Lately my computer has been rediculously slow with everything, but aside from that my issue is with my start up disc. I would have over 1.5 GB of space left, open up a photoshop file...make some alterations and save...and all of a sudden I have NO SPACE left. These alterations created the photoshop file to be like 50mb more. Its a 200mb file. So how can I go from 1.5 gigs to saving a 200mb .psd file and all of a sudden 0 hd space?
Sometimes I couldnt even save the .psd because when I opened it all of a sudden I have half a gig now. And even if I had half a gig why wouldnt I be able to save? I go to save and sometimes it says "your start up disc us full" - Is this different than my harddrive?
Is photoshop using some sort of weird caching thing?

Looks like my company upgrade got postponed for a few months due to budget constraints. As a short-term boost I'm looking at getting an SSD, but I'm a little worried about the capacity.
I currently have a 320 GB drive and have been able to get by usage down to 93 GB. Will I need to worry about leaving headroom with a 120 GB SSD drive?
Do you optibay or use external hd's? I want an SSD for my new 13" mbp but prices and storage limitations are what are holding me back right now.
