MacBook Pro :: Do Mbp Loose Performance While Operating On Battery?
Apr 29, 2010
I just ordered my first mac a few days ago online, and seeing that almost everyone takes advantage of the suposed 10h battery of the 13', I wonder if it gets slower when you are using the battery.
my current notebook (compal FL90) is considerably (much) slower when it is not powered to the grid especially if I'm running photoshop for casual editing.

I'm looking to purchase 12 GB of Ram for my 2009 Octo Mac Pro. I've heard it is always better to go with 3 sticks of Ram rather than 4 with the 2009 Mac Pro, but is it better to go with 6 sticks rather than 3? What I'm looking to do is at 12 GB with either 4GB x 3 all on one side, or 2GB x 6 with 3 sticks on each side. I would prefer the 4GB sticks so I can upgrade later if needed to 24 GB. What I wanted to know is will I lose performance by only have 3 sticks of memory rather than 6 or does it not matter?

It's sort of come to my attention there's a few of us who are having *experiences* with a loose cover/latch. I wouldn't call this an *issue* at all, (yet) or it could be a problem with us being too picky. Either way, I'd like to know.

Apple Macbook Air late 2010, has been giving me poor battery performance even after replacing the battery under warranty. I am unable to find a solution, even the local apple service provider seems confused. Should I go for a replacement?My Macbook Air runs on the OSX 10.7.3 with all updates as on date. I use only softwares such as Microsoft Office for mac, Safari, Mail, iChat, iTunes regularly.
Info:
MacBook Air, Mac OS X (10.7.3)

Is it possible for a sharp and sudden fall to disconnect the battery in the Macbook Air? My friend just emailed me--her husband dropped the MBA from the kitchen table to the floor (so just under 3'). She has an X icon where the battery icon should be and for the first few restarts, she's had to reenter wireless password information, as well as date/time. The MBA works fine when it's plugged in. But there's "a teeny dent in the upper left corner. Really tiny."

Twisted body, slanted keys, loose keys, battery cover, and freese trackpad. Lets see how many members in this forum is suffering from Apple's poor Quality Control in these new Macbooks!

i remember in Leopard you were able to select different profiles in the battery menu on the menubar. There was an option for high performace and power saver, etc. In snow leopard this is not an option, is there anyway I can bring those settings back? Or is snow leopard automatically adjusting processor power?

Just wondering what the norm is in terms of where my battery levels should be. When I first received my MBA 2 weeks ago, the full charge mAh capacity was around 7100. Now after 6 cycles, the full charge max mAh is 6678.
Is this normal for the max to drop so much after only 6 cycles? Just wondering what others are experiencing in terms of battery performance.

I have a MacBook (late 2007) and I've noticed that my internet crawls when I'm using the laptops battery power. I can be downloading a file at 200 kB/s under A/C power, and as soon as it goes on to the battery it'll drop to 10 kB/s. I'm assuming some kind of power saving is being activated, but this has only happened recently. Around the same time this started happening, I updated my computer to 10.5.8 and I also turned in my computer to the Apple store to have the palm rests replaced for having cracked under the weight of the lcd. Would this problem be caused by either the update or the repair, and if not, what could be causing it?

I just switched my old 120Gb drive with a 320gb one (FUJITSU MJA2320BH G2 -- speed should be the same as my old one), and I'm noticing a drop in battery performance of about 20%. Is this just a coincidence?

increasing the amount of RAM in a MacBook Pro (latest model unibody 15" i7 processor). If I increase the amount of RAM in this laptop from 4Gb to16 Gb, should that in and of itself result in a decrease in battery performance? This is assuming no increase in number of active programs, etc. A friend of mine was told by an Apple employee that just increasing the total RAM in a laptop would result in the battery draining more quickly. I am no computer genius, but that does not sound right to me? After all, why should the battery work harder if the excess RAM is not being used at the time.

What effect will the macbook have, if i fully charge and discharge the battery on a daily basis. I will leave it running on battery power when i leave for the day, and let the battery drain/discharge fully through the night.I will hook it back up in the morning to have it fully charged, may be 30 - 60 mins after it being fully charged, i will pull the power out and run the laptop the whole day on battery.

I know that Flash uses more battery power. However is that only when you are actually using a window that needs Flash. Does just installing it decrease your battery performance in any way? I am running into lots of sites that require Flash and I would like to install it but not at the risk of severely limiting my battery usage when not actually using it.

I am not sure if it only my macbook, but I notice a slight performance drop when I run on the battery v the AC. I notice that my application load slower, folders open slower and expose and spaces response is also slow as well.

I am planning to buy a new 13" MBP but I am kind of concerned on the battery performance.
Specs:
a) 2.26 GHz CPU
b) Upgrade RAM to 4GB
c) Upgrade HD to 500GB 5400 WD
d) Brightness at 70% / with keyboard backlight / Bluetooth OFF
Questions: (Can you give me an estimate on the following)
1) How long will the battery last if I play Facebook games nonstop (poker / mafia wars / cafe world / etc.)
2) How long will the battery last if I play Sims3 nonstop?
3) How long will the battery last if I watch a DVD movie nonstop? (from the drive)
4) How long will the battery last if I type documents nonstop?
BTW, can this MBP 13" play sims3 in the default normal settings?

Earlier today, maybe around 3PM, I was using my laptop, and it was charging and it was maybe around 60% battety life when out of no where it just shut off and even the light on my charger went out. When I turned it back on, the fan was running and there was an X over the battery icon. I've tried turning it off and on, and leaving it alone for a few hours, to see if it would resolve the problem but it didn't. It is currently 9:52PM, I'm still experiencing these problems and I'm using the exact laptop to type this, but I don't know how much battery life is left.

Planning on Purchasing one of the New Aluminum MacBook Pro's. I would like to know what are the best ways to have your battery last longer and hold the normal charge? Also on the Battery Section on [URL] it says it not good to have your computer charging all the time but then people on the forums say it's better to keep it plugged in! What is it? What should I do? Listen to Forum users or Apple). Also what is a good setting for the Screen Lightiness? Is HalfWay see able? What about 75 percent notches. Will lowering the battery brightness save battery?

I've been looking for some info on the older 2007 MacBook Pro battery specs and stats, etc., but have been somewhat unsuccessful. Lately my MBP has been draining the battery at a much quicker pace than normal. This machine is only a year old now (however CoconutBattery says the battery is 16 months old). Still, the battery capacity shouldn't have diminished too significantly. Before I restored the Mac and installed the Windows 7 Beta, I could average 3-4 hours on a full charge. Normally, I would keep WiFi + Bluetooth enabled, an external monitor attached, several USB peripherals plugged in, and the main display would be set to maximum brightness. 3-4 hours was pretty nice considering the amount of power the machine could have been using.
After I partitioned my hard drive, the battery life was cut in half on the OS X side. Windows 7 power management was even worse. I figured that there may have been extra disk activity causing this problem. After I finished toying with Redmond's new OS, I removed the Windows partition and moved on from there. I know after I removed the partition, I was getting excellent battery life initially. Once that short period ended, it went downhill from there. The battery meter has become surprisingly accurate as of late; in a minute or so, you can easily watch the percentages drop 1-2%, which appears abnormal. I can manage 3 hours on a single charge at best, but I usually get less. I decided to take greater care in cycling the battery, in hopes of nursing it back to health, so to speak. It doesn't appear to be working so well. Enabling WiFi and other peripherals only drains more power, but turning them off again adds only 5 minutes. So when I'm using several devices at once, I'm lucky to get a little over 2 hours. Turning off menu items and background apps does nothing either.
It's been this way for several weeks now, and yet, iStat, System Profiler, and CoconutBattery all report seemingly acceptable and consistent battery info: 86% Battery health, around 180 charge cycles, and the capacity is around 4700mAh (out of the original 5500) for now. The computer believes all is well. Performance says otherwise. I'd like to think that physically the battery seems to be okay. I've cycled and calibrated it several times. I have read reviews that indicate that Santa Rosa MacBooks with new batteries have averaged similar runtimes to the ones I experience now, but I know mine has usually bested all of the reported tests. It just seems wrong for the average runtime to go from almost 4 hours to 2 when the battery is (supposed to be) maintaining the same health level. I have AppleCare if it needs to be replaced, since this drastic change in usage time is very noticeable and counterproductive for me, but it could just be the computer (or me for that matter). Is this behavior normal for a battery of this age? What should I look into? If this is normal behavior I can live with it, but I would prefer to get as much out of the one I have.

I was running some networking performance tests the other day for some research project. Essentially I have 7 computers on a LAN that is not connected to the Internet - all computers are connecting wirelessly. I have one computer function as a server and it multicasts pings to the other 6 computers at a constant rate (e.g. sends a packet every 2 seconds).I noticed some odd behavior - 4 computers received the packets in about the right time intervals (every 2 seconds), but 2 would get packets at intervals of roughly .92 seconds and 1.12 seconds consistently. I realized that these 2 computers were running on battery and not plugged in. Plugging in all computers got all the computers receiving packets at the same time.

It is slighly loose, and I know it won't be a big deal to fix. I'm just scared that it will cost a lot to repair.

Seems to be a pretty hot topic right now, personally I want to loose it since I never use it, and would far rather have an external DVD drive for ripping the odd movie than lugging an external HD everywhere so I can access all my photos.

so I have recently purchased my pro and just noticed that if I pick it up at an angle the screen moves.
My 3 year old pc laptop does not do that. Is it just me being anal or is it a problem?
I just want to make sure because I have already taken my iphone4 back 3 times and my ipad. So I beginning to think its me!

Each and everytime I put my Macbook Air 11 to sleep, it loses internet connection and I have to go into the Wi-Fi panel to rejoin my home network. It's quite annoying because I like to close my MacBook and hide it in the television cabinet when it's not in use. The first time I encountered this problem was when I left the MBA for an hour to download some big files, only to open it back up and find the download had not moved at all since I closed it.

I bought my Macbook Pro last september along with my Thunderbolt monitor.Everything was working until today (yes today was my first time bringing my Macbook Pro elsewhere) and when I moved it, the display shut off.then I realized that when I just move the Thunderbolt plug around it would turn on and off the display depending which side I would hold. would it be a problem with the Monitor cable? or a problem with the Macbook Pro itself? both are still under warranty, so I'm not worried, but it saves me the trouble of lugging either (especially the monitor) back to the Apple store.

Often my MPA and/or my friends MBP drop Internet connection! The only way to get it connected again is to restart it over and over again.
