Does OS X Mavericks shorten a battery life time in Retina Macbook Pro?

Thank you again for your advice, and I am sure your right but as a simplton I have to argue that the problem is asociated with Mavericks in so much as - one does not have any of these issues running any previous OS and therefore, the issue is a Mavericks one when upgrading. It is all to easy for the techies to say "its on your mac' if proper testing and development had been done on, at the very least , the apple software the upgrade should not have issues. its a bit late after installing and having Apple update remind you all the time to upgrade then to say sorry - your fault for having incompatible software like mail . However, I suggest you look at the other apple logs / site that complain of battery drain after mavericks they all point to issues that are as a RESULT of the upgrade and yes technically you will argue that is because the original software in not compatible or some such. Lets not go on and on I have sorted the problem - don't use Mail and battery life is OK, Use mail and watch it drain. Once again thank you please don't feel the need to respond.

How can I do a clean installation of Mavericks 10.9.1 on Late 2013 Retina Macbook Pro

Hi I need some help -
I bought a late 2013 15' Retina Macbook Pro and it was shipped with 10.9.0 build number 13A3017.
Now 10.9.1 is out, and I wanted to download the full installation image and burn it to thumb drive and do a full clean re-installation.
But I just found Mac App Store doesn't allow me to download the full 5.29GB installation image from https://itunes.apple.com/us/app/os-x...ks/id675248567, and my current 10.9.0 can only be _upgraded_ to 10.9.1 with the 395MB incremental update package from http://support.apple.com/kb/DL1712, this upgrade package is described as "It includes all updates from OS X Mavericks 10.9.1 plus system specific enhancements to improve the stability and compatibility of your Mac."
So maybe the full 5.29GB 10.9.1 which is available on Mac App Store is not compatible with the 2013 15' Late Retina Macbook Pro?
I just downloaded the upgrade package from Mac App Store and now I'm running 10.9.1 build number 13B3116 fine.
So my questions here: I really would like to do a clean full re-installation of 10.9.1. Where can I get the full installation image which is compatible with 2013 15' Late Retina Macbook Pro?

There is a way to get yourself a fully functional install file for a Late 2013 model.
1. Format a USB stick
2. Reboot the Mac, and hold down CMD-R to get into recovery mode
3. Start a new installation and choose the USB stick as a target. You should be able to choose your normal hard drive as a target, too, because as long as the installer package is downloaded, no data should be erased, but when you decide to use a USB stick, you're on the safe side.
4. The Mac will be downloading the install package. This takes a while, the time remaining shown is not correct. If you need to have an idea how long it will take you, choose the log from the help menu during download, it will show you how many chunks are already downloaded (it was 504 chunks total for me).
5. When the download is ready, the Mac reboots automatically, pull the USB stick when it does. If you're not before your computer when this happens, don't worry, when you come back, you will be in the setup program. Just switch your machine off by pressing the power switch for more than 10 seconds, and then pull the stick.
6. On the stick you will find the "OS X Install ESD.dmg". Copy that file to your Mac (it's the only file you'll need from the stick. After that, you can reformat the stick and use it for the next step).
7. You can use this file to finally create a bootable USB stick if you follow the instructions that you can find anywhere on the net or in this forum.

Battery Life on my 17" MacBook Pro

Hey guys,
So I just bought a early 2011 17" MacBook Pro and was wondering what the battery life should be like. I have the brightness on half, keyboard lights on full, and I have been on facebook, apple, and watching a movie, and the battery life is already on 63%. I don't know if this is normal, or is there something wrong with my battery? I called applecare and they said that it just depends on usage, but I'm still kind of worried because the computer was $2458 and I want to make sure that everything it in check for this kinda of money.
Please answer/reply soon!!!!
Alexander

So would what I was doing be considered heavy usage? Thanks for answering
Depends. Screen brightness on half is good, but keyboard lights on isn't. If you're using the internet, presumably you're doing that wirelessly, and having AirPort turned on drains power faster due to the need to constantly broadcast radio signals. (Bluetooth is the same.) Watching a movie isn't a low-power thing to do, and if you were watching it from a DVD in the optical drive, keeping that spinning eats even more power.
What you were doing isn't as high a usage as, say, playing a graphically-intense 3D game, but it's not something that will help your battery last longer either.

Battery Life really terrible on MacBook Pro...

I have a MacBook Pro 17 inch and it has only 101 cycles on battery, yet it only lasts for about 2 1/2 hours max when fully charged. The computer is 1 1/2 years old and I just use it for personal use...which really isn't that much. Any thoughts? Thanks

My Macbook Pro is 4 years old and I still get approximately 5 hrs of battery life under normal usage with no more than 2 applications open at a time. Playing downloaded games or games played directly from a cd , I get around 4 - 4 1/2 hours. I faithfully calibrate my battery every other month per my user manual schedule.
I never watch movies while using my battery.

HT1338 How can I conserve battery life on my new macbook pro? I got it 2 weeks ago and am noticing that the battery depletes quickly. I dim the screen and keyboard backlight & mainly use Safari (multiple tabs).

Appreciate any help!

     My daughter also just bought a Mac Book Pro 13" with the same issue. When we migrated over from the old computer, we brought over only her documents, no applications, and she was getting only about a 2 hour battery life on the new MBP. Somewhere in the MBP threads in this forum someone who was experiencing this same battery life problem said he was told by an Apple Genius in a retail store to try setting up a second user, and then to try working out of that user only. So we set up the second user, logged out of the old user, and the battery life readout is now about six hours after a charge when my daughter is logged in as the new user. If she needs old documents or other files she can always log in as the old user to use them, but she rarely has to go back. Whenever she is logged on as the old user the battery life shows under two hours, but when she she logs out and logs back in as the new user it jumps back up to around six hours.
     There seems to be no need to eliminate the files etc. that reside under the old user. As long as my daughter is logged out as the old user and logged in as the new user, the battery life is much better. Weird solution, but it seems to be working. She is running Lion 10.7.4.
     Hope this helps.

Battery Life on brand new macbook pro 15 inch i5 only lasting 3 hours

The battery on my macbook pro is only lasting 3 hours with light use...If i'm watching a video or on a game it lasts maybe an hour or 2. I charged it fully when I first got it out of the box 2 days ago.
I have tried calibrating it which worked a little bit. But still nothing like the promised 8 hours. Not even near 6 hours.
Can anybody help?

I tell you how to maximise it mate .. Fully charge your battery and leave it on charge for 2 hours .and then create the minimum power consumption scenario ( kill bluetooth , minimise brightness , kill all apps etc ) AND THEN remove the plug .. use at this state until about 70% charge and continuously monitor the capacity like I mentioned earlier when you see it hit a high, plug it in you will see now that will become your permanent capacity .. allow full charge and leave it plugged for a day . .repeat the same .. after about a week now this time do the same but reduce down to the 40% range and always plug in at a high capacity point..you will train you r battery this way ..
I am glad I could help .. altho it took a bit of fighting the external obstructions it's all good
take care ,,

Is anyone else experiencing shorter battery life issues on a MacBook Pro?

I downloaded Mountain Lion and I swear my battery is just zipping down to zero. Is it just me or is this a gerneral problem? Is there anything I can do to rectify this issue?

open up activity monitor - see what's running under ALL PROCESSES - highlight anything that's using 10% and up on the %CPU section and hit quit process....
turn bluetooth off if you're not using it...
turn automatic brightness off
turn off infrared remote receiver if you don't have an Apple Remote
set your screen brightness to 50%...
I'm running Mountain Lion and am getting over 6+ hours...
good luck...

Can't install maverick on my wiped out late 2013 retina macbook pro. Please help.

So, i decided to install windows 8.1 alongside mavericks on the mac and tried using bootcamp which failed, so i manually created a partiton using disk utility which worked, later i decided to create a shared partition so windows and mac could share files on the harddrive. i decided to format the drive in windows which i thought worked well, until i had to restart the computer only to realise it had completely wiped out my mac os x and recovery partition. Ive tried everything possible, even have a bootable maverick available on usb, yet everytime i choose the maverick setup to install using the (option) button it shows a stop sign. please help me figure this out. Final year student in architecture. Any information would be appreciated.
thanks.

Hi dodzi_k,
If a reformat from Windows removed the Recovery partition and is preventing the reinstall of Mavericks, you may need to boot to Internet Recovery to reformat the drive. You may find the following articles helpful:

Hi. Does using the cover lock help battery life?

Hi. Does using the cover lock help battery life?

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Does using bluetooth headphones dramatically decrease battery life in ipod 5

I have a 64gb version of the Itouch 5 and recently started using jaybird brand bluetooth headphhones. At first everything worked fine but now the battery inthe Ipod only lasts 4 hours even when niot using it. Has there been any known issues with this?

Yes, and no. The headphones aren't sucking the battery out of your 5th Generation iTouch. USING BLUETOOTH, will. Its like running a game on your iPod for a while. It will drain the battery more quickly than with just listening to music. So running apps, bluetooth, etc, WILL shorten your battery life.
HOW TO FIX IT:
When you are not using the headphones, turn the bluetooth off through the general settings in your itouch. Then, while you aren't running the headphones, it won't suck the battery life out. When you use the headphones, turn bluetooth back on. Leaving bluetooth on is still leaving the iPod in bluetooth mode, which is running down the battery because it takes extra charge to run bluetooth. Hope this helps!

penny41,
Thanks, glad it helped you to check your battery status.
Something else to look at would be the cycle count, as you mention that your computer is "ancient". If you have a high number of cycles, it may also be a sign that the battery is tired and possibly nearing it's life span, and may possibly need to be replaced soon. If you see that again you may try a SMC reset to see if that helps, but if it continues you may need a new battery at some point. The battery icon will usually say needs service, or something to that effect. For the later MBP's Apple claims a life span of up to 1000 cycles, of this also will be dependent on who the battery is used, on the older ones I'm not quite sure what the claims were, and I don't know how old "ancient" in your case actually means.
I provide this for your info, so that you understand what may possibly be occurring.
I wish you the best.

Follow directions for what applies to your machine, a battery you can remove, or a battery you should not remove yourself.

How long is normal battery life for late 2011 macbook air?

How long is normal battery life for late 2011 macbook air?

I would also note that the 11" and 13" have different lives. While the 11" has a smaller screen to drive (and thus, in theory, less power) it also has less space for a battery. So it turns out the 13" has a longer battery life, all other things being equal (same usage and the like).
Clearly what's "average" will vary by user. Depending on what I'm doing, I can get Apple's rated life (or darned close) or I could end up well short of that life. The "rated" life is 5 hours for the 11" and 7 hours for the 13" but that is, at best, a very rough approximation. As the picture in captfred's response makes clear, the actual usage of the machine has a huge influence.
