Is customizing macbook affects its battery life?

Hey guys! I am wondering if I will buy a customized MacBook, for example, a MacBook Pro 13" Retina upgraded processor from core i5 to core i7 and memory from 8GB to 16GB, will it affect the battery life of the macbook, say from 9 hours of battery life, it will become lesser because of the added processor power.? Just asking.

If i download CAD software how will it affect my battery life and macbook speed?

If i download CAD software how will it affect my battery life and computer speed?

Welcome to Apple Support Communities
CAD software requires the best CPU and GPU performance, so your battery life will be affected while running CAD apps. The same will happen with your computer performance with other apps, so if you do not need any application while using CAD apps, it is better to close them.
However, your battery life and your computer performance will be the same if they are closed. The only exception would be if your MacBook's hard drive is running out of free space

Improving the 2013 Macbook Air i7 battery life

Hi
I've checked couple of topics related to this issue seems many people suffer from this problem, i7 8gb ram with 512gb ssd Macbook air has some issues with its battery life it reduced very quickly. I've applied some techniques -like smc reset,deleting launch daemons and agents- and have an improvement in battery performance. Now the point is, when i do the EtreCheck there are many kernel extensions displayed in the report. Is there any way to delete them and slightly improve the battery life?

Is there any other suggestions that you may offer ? Many thanks

You can use the new Activity Monitor to determine a unitless "Energy Impact" value:
You can also click the battery icon in your Mac's menu to reveal significant energy hogs (UPS is shown below):
Whereas Apple recently updated their apps to take advantage of Mavericks' energy saving algorithms, few other vendors have. I surmise the prominent "Energy Impact" hall of shame addition to the new Activity Monitor is Apple's subtle way of nudging them into compliance.
Google's plethora of invasive OS X system modifications is a popular reason for excessive battery drain. Google has yet to demonstrate the ability to develop efficient OS X apps, and one can only surmise they are not interested in doing so. If you elect to use Google Chrome or any other poorly implemented OS X programs, you must accept the detrimental effect they will have on performance and battery life.
If you no longer use a Blackberry, uninstall RIM's software. Be sure to follow its uninstallation instructions.

Just bought a mid 2012 13 in macbook pro. Battery life is only 3 hours. Thoughts?

Just bought a mid 2012 13 in macbook pro. Battery life is only 3 hours. I was under the impression that it would last 7 hours. This is with normal internet browsing and text editing. my brightness is not all the up and bluetooth is off. Thoughts?

im having the same problems, bought my 13" MacBook Pro last week and the battery is terrible on it, but i googled it and a lot of other people are having the same issues

Can i use my ipad mini while charging? Would it be affect he battery life span?

Yes.
No.

Does the upgraded MBA 11'' from 1.4Ghz to 1.6Ghz affect the battery life?

Im looking into buying 11'' MBA and i still cant deside if i should upgrade the CPU.
Surely i will upgrade the RAM to 4GB.
But Apple Store staff adviced me that if i upgrade CPU to 1.6Ghz it may reduce the battery life from promised 5hrs to around 4.5hrs... Is that true? Personally i think that is maybe not really true, cuz normally any OS have an option to control and set up a limit of the CPU performance and frequency speed in regards to manage the baterry life... it even can be adjusted either manually or automatically.. am i right? And actually if you dont use CPU intensive programs so it won't consume more power, right? And even in such case also you can set the limit of the CPU performance to save the battery...
So does the upgraded CPU affect the battery life or not ?
And another matter - will the upgraded CPU get overheating sometimes and will it be "throttled" to control overheating ? as i heard...

Higher GHz = More Power = Lower Battery Life
Personally i think that is maybe not really true, cuz normally any OS have an option to control and set up a limit of the CPU performance and frequency speed in regards to manage the baterry life...
And actually if you dont use CPU intensive programs so it won't consume more power, right? And even in such case also you can set the limit of the CPU performance to save the battery...
If that were true, then why pay the xtra $100 for 1.6 GHz???
So does the upgraded CPU affect the battery life or not ?
Yes

Does the backlight affect the battery life? & new update problems...?

i've been told that affects the battery life and i like mine bright but if it affects battery i will keep it down..
and does anyone else notice that the new update is glitchy? or is this just me..?

When did you purchase it and how much memory does it have? Does it have volume buttons on the side? Is the black plastic antenna window on the back oval, or is it square and cover the corner of the iPod?

Can my blue tooth keyboard affect iPad battery life?

For some reason my battery life isn't as long as it once was and it hit me that it may be from leaving the blue tooth keyboard in the on position. Would this run the battery down more quickly?

My experience with using a BT keyboard is that it has a negligible affect on battery life. The connection drops if I'm not using it for a while and picks up again when I start typing. I am using a Logitech keyboard designed specifically for iPads.

Why doesn't the Macbook Pro's battery life last?

Why doesn't the Macbook Pro's battery life last anywhere near 5 hours, as advertised? This is my second one and it lasts 2. It's false advertising, and Apple doesn't seem to making a big deal or know anything about it, which i'm sure they do. Since their general practice is to deny problems exist in all their products, i'm here to make it known that the most recent Macbook Pro has a severe battery issue and it needs to be addressed.
I'm running OS X 10.8.3, Bluetooth is off, and haven't installed any third party software.

My MacBook Pro is over a year old and still gets 2.5 to 5 hours, depending on how intensively my application activity is hitting the CPU and disk. Remember that battery life depends on usage and component loads. You could get 1 hour editing HD video since it would hit all cores and slam the disk constantly, or 8 hours in a cabin in the woods with wifi and Bluetooth turned off, only writing text files, and with the backlight turned down and no disc in the drive. You should check Activity Monitor to make sure you don't have some processes using unusually high amounts of CPU for long periods of time (like browser tabs running Flash ads in the background, chewing up CPU and battery power without even being seen).
Like mende1 says, there are not huge numbers of Mac users getting only 2 hours, or the world would have heard about it by now and MacBook sales would be down. If you are only getting 2 hours there is something going on local to your machine or usage habits.

That's not strictly true. Apple has often announced updates or repair/exchange programs to address various problems that had come up over time. Maybe not always, but it does happen. They also have often helped me and my friends when we brought in Macs that were out of warranty and had problems. They had no legal obligation to work on our Macs for free, but they did anyway.

Plug in the macbook will affect the battery life ?

is it true that it's not recommended to keep my macbook plugged in all the time while I'm using it ? will that help or kill the battery ?

I believe this is incorrect. On Macs with non-removeable batteries, keeping it plugged in will not affect battery life/performance as long as you run it on battery 1-2 times per month to around 40%.

Macbook Air Poor Battery Life

I have a mid-2012 Macbook air and I've noticed recently my battery life is horrible. I've read every single other thread about this issue but nothing really helped and even the most recent is from a couple of years ago. Obviously now it's 2015 and my macbook is running on Yosemite, so its not the battery issue that everyone seemed to have with Mavericks.
Just writing that small section I went from 73% to 68% and at the current 68% I only get an estimated 2 hours and 10 minutes remaining. I've also had only Safari running this whole time.
Option clicking the battery icon reveals that the condition is normal, as well as the power system report. It also has gone through only 441 cycles, no where near its 1000 cycle "limit" and its health is already down to 77%. While obviously the condition is normal and doesn't say I need to replace the battery I feel that I should, based off of everything else.

Have macbook air from mid 2012 - I installed Yosemite November 2014 and since then I'm having problem with my battery - it has been draining super fast - 4hrs battery life now compared to earlier 8hrs.
I reinstalled Yosemite, didn’t help and then made a clean reinstallation of Yosemite about 5 days ago and there is still the same drain issue.
Thank you in advance!

Macbook Air Terrible Battery Life

There are a series of threads on these forums regarding the rare case where Macbook Airs get terrible battery life on Mavericks, and some of them have numerous posts telling you to make a new thread about your specific issue. Here's mine.
The issues began when I did my initial Mavericks update. I had a series of really bad things happen, so I did a cmd+R reboot, and reinstalled the OS. It didn't help, so I scheduled a Genius appointment, and they wiped the drive and installed Mavericks clean.
All of the issues are gone now, except for one: my computer gets less than half the life it did on Mountain Lion. I used to get 14-16 hours of battery life on Mountain Lion when nothing was running. I just charged it to 100% and had just 6 hours of estimated life.
I've reset both the PRAM and the SMC, and neither helped. Might you have any further ideas on how to fix this?
Note: I know that Google Chrome is less energy efficient than other browsers. With that said, I used to still get well over 10 hours at 98-100% battery life on Mountain Lion with Chrome open. My usage of Google Chrome is a constant in this equation; this issue can't be so easily dismissed as being an issue with Chrome, I think.
Here's a screenshot showing a number of things (no apps being open, the poor battery life, and activity monitor)

This may be because Spotlight is indexing your harddrive, do not interrupt it before it's finished and then it'll be much faster and your battery while behave normally if not better !

2013 Macbook Air 13" battery life not as good as advertised

At full charge, the estimated battery life read a little over 17 hours. At 97%, it now reads 15:39. Like I get this is vastly better than the older Macbook Air, but it still falls quite short of the 24 hours advertised on the website. Currently, it is still at 97% but now the estimated battery running time reads 14:59. Is this normal? I accidentally drained my battery twice since I bought it at the beginning of August, and I understand that's not good for the newer batteries - could this be the reason? My screen brightness is at 50% and I have no movies or music playing. Safari is the only ap I have open.
I'd appreciate any ideas or help with this problem (that is, if it is one).
I just looked at the estimated time again, and while it is still at 97%, the estimated remaining time is at 13:48. It's taken me a little over a minute to type this.
I'm not very tech-savy - is there something wrong with the way I understood the advertised battery life?

The Air is nowhere advertised for 24 hrs. batt. life......... in any configuration.

MacBook Pro 15" Battery Life Issue

I have a MacBook Pro 15", with a processor 2.4 GHz Intel Core i7 and memory 4 GB 1333 Mhz DDR3 running OS X 10.7.2. It was purchased only a week ago and I'm noticing horrible battery issues. I have checked Activity Monitor and nothing, even while I'm browsing the Internet is using a large amount of CPU, so I'm a bit confused. I know that this is an issue that many people are facing as I can see from all the other discussions. Has anybody found a solution to this issue at this point, or has Apple released any information about an update ot fix the issue, anything at all? Just pretty disappointed since I came from an early 2008 MacBook Pro which had about a 4 hour battery life and was expecting a new Mac with 7 hours at least. Thanks everyone for the help, sorry for a question that I'm sure every is sick of.

Calibrating the battery is a slightly more specific process than Chris suggests. Instructions are here:

It's important to follow them to the letter, paying attention to the specified wait times after charging and discharging.

1. Follow these instructions, or these for OS X 10.9 or later.
2. In the Energy Saver preference pane, uncheck the box marked
Enable Power Nap while on battery power
3. You can also try resetting the SMC.
4. Make sure your system is up to date in Software Update.
5. Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

Is customizing macbook affects its battery life?
