MacBook Pro :: Battery Is Just Giving 2 Hours Backup?

Apr 22, 2012

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).

MacBook Air :: Time Machine Backup Takes Up To 6 Hours To Do A Backup Of About 30GB?

Jan 9, 2010

Just wanted to check if he problem was unique to my MBA (Rev B, HDD) or you notice it too ;

My Time Machine backup takes up to 6 hours to do a backup of about 30GB. And each backup size is 31.5GB everytime !!

I have the following Config - 80 GB for OSX (53GB Free) and 40 GB (10GB Free) for Win 7 on Bootcamp. Sometimes I wonder if TM making a backup of Win 7 also everytime. (Does it mean - In a way its good, that means I should be able to restore the entire hard disk from TM including Applications, Win 7 , bootcamp and all the programmes installed in Win 7 in case I have a problem ?)

But the speed should still be fast... 6 hours to do a 32GB backup is torturous specially because then I have to leave the machine alone and cannot use it.

MacBook Pro :: Battery Draining While Plugged In And Idle?

Mar 9, 2012

This morning I set to work on my laptop as usual. I typically leave it plugged in while not moving around, and today was no exception. I h ave a 15" macbook I purchased in December of 2010, and it's currently running OS X 10.6.8, if that makes a difference.

Anyhow, when I started up my Macbook and set to work, the battery was fully charged (indicator read that it was fully charge, and that the power source was the power adapter). The power adapter light was green. I then stood up and did some work for roughly 2 hours away from the laptop. When Ieft, I put the display to sleep - In the background the machine was still running a webbrowser (reading an all-text page) and preview (a PDF was open). This is nothing out of the oridinary, and I do it all the time usually.

What was unusual was when I returned to my machine after 2 hours of idling (with the display asleep)  to find that my battery had been almost completely drained. The power adapter light was now orange, and the indicator showed that the battery was only 4% charged. The power source was still displayed as the power adapter.

I understand that during intense processses the Macbook will draw from the battery AND the power adapter - But my Macbook was simply idling! I can't fathom that a webbrowser and Preview would require THAT much draw for power. In fact, I've run my Macbook MUCH more intensely for much longer periods of time when running Final Cut and Adobe After Effects and NEVER seen this issue before.

Is this an indication of a failing battery? Ever since I noticed this, the charging time indicated has held steady at ~1:13 (that's been about a half an hour now). I don't know if the Macbook will discharge the battery completely every so often by itself, or if the battery is just failing and that's why it went from 100% to 4% in just under two hours while idle.

MacBook Pro :: Maximum Battery Capacity Decreasing

Jul 23, 2010

It's only been a month&half with my MBP 13". Coconut battery claims my MBP is 3 months old now (obviously manufactured 2 months prior to my purchase). Currently I have 8 cycles. 2 calibrations (one on first day, and one yesterday). It went from 98%-97%. Obviously this isn't a big jump, and I know i'm just being paranoid. I don't understand how people on the forum says after calibration your maximum battery capacity should go up, and it refreshes the system or something. It nearly dropped by a 100... What the hell? How do I make it go up? It's only a month old !! Shouldn't it be at 100% or atleast 99%? Some people on this forum claim that they have over 100%+ after MONTHS of usage...

MacBook Pro :: New Battery Much Less Than 7 Hours?

Jun 15, 2012

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?

MacBook :: Battery Capacity Only 3 Hours

May 4, 2009

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?

OS X :: MacBook Pro With Only 3 To 5 Hours Battery Life

Sep 30, 2009

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?

MacBook Air :: Poor Battery Life - 3 Hours With Normal Use

Feb 21, 2008

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?

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 :: 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.
