Battery Life on a Refurbished r/MBP (Oct 2013 model)

Last week, I just bought a refurbished MacBook Pro with Retina (Oct 2013 model) and notice the battery only lasts about 6 1/2 hours. This is supposed to be the newest iteration of the MacBook Pro line and I was told that the battery is supposed to last 8 hours or longer. Is 6 1/2 hours about what it should be lasting? Or does this suggest that it was used heavily and that they didn't put a new battery in it? I'm still within the 14 day time window to return/exchange it and I would really appreciate some feedback. I'm thinking of bringing it back to an Apple Store and exchanging it for a brand new one, but ONLY if the new ones really do get battery life of 8 hours or longer. Please tell me what you think.

Hi ChrisfromHongKong,
Thank you for your informative response and your recommendation to download "coconutBattery". In addition to doing what Dominic23 recommended, I will look for Coconut Battery and see what else I can find out about my battery. I really need to make a decision about whether of not to exchange this computer quickly; ideally by tonight. I've got about six days left on my 14 day return/exchange window. However, because the nearest Apple store is more than an hour and a half drive (each way), going there after work one night after work will be a bit much. So if I'm going to do this, I will need to do it this weekend. But I still don't know if what I am seeing in terms of battery use is normal for light usage or symptomatic of a problem that would be best resolved by exchanging it.
I tried looking at Activity Monitor this morning before I left for work, but what I saw there made no sense to me. What does "Time on Battery" mean? Mine says 57:13. Does that mean it has been 57 hours and 13 minutes since I last charged it? Or does it mean that it has been used for 57 hours and 13 minutes? I only have this computer a week and have definitely not used it anywhere remotely near that much. If you (or anyone reading this) know what "Time on Battery" means, I'd appreciate your sharing that information with me.
Thank you again.

Poor Battery life under Bootcamp W8.1 - MBP Retina late 2013

I finally managed to get W8.1 installed under bootcamp by installing W7, upgrading to W8.0 and upgrading again to W8.1.
The battery life is pretty poor at the moment. Just simple browsing and emailing is showing 25% usgage around 1 hour. I guess this is because it's using the NVIDIA GT 750M full time, rather than the Iris Pro?
My question is... Is this something that Apple normally fixes with an update? I definately don't need the power of the GT 750M, so I'd prefer to use the Iris Pro (I'm assuming this is less power hungry!). Even if it just gave a choice, rather than automatically switching, that would be great.
Thanks

Thanks. This is the first time I've used bootcamp on a dual graphics card machine, so I wasn't aware of this 'shortcoming'. Shame, but there are worse things to worry about

Is it any differences in battery life between the different processors (MBPr late 2013)?

Is it any differences in battery life between the 2,4GHz i5, the 2,6GHz i5 and the 2,8GHz i7?
I'm planing on buying a macbook pro 13" but I'm a little bit uncertain which processor I should chose. I want as much power as possibly but if it's any significent battery diffrences, then I would chose battery over power. I've read that there is about 45 min diffrence between the 2,3GHz and the 2,6GHz in the 15".

I imagine that there are but since Apple makes no such distinctions, I suspect that the differences are not that great. I have not seen any reports or studies to that effect.
If battery life is of paramount importance to you, consider a Macbook Air. The advertised battery run times are significantly longer than the Macbook Pro.
Ciao.

IMovie not free for Macbook Pro, late Oct 2013 Model

Hi,
How can I get iMovie to be free again on the Apps Store.
These links did not solve my problem.
https://discussions.apple.com/message/23806749#23806749
https://discussions.apple.com/message/25262275#25262275
At the Apps Store accounts page, I cannot see the tabs stated in this link.
http://support.apple.com/kb/ht4928
In addition, all iWork software are not free also.
Please help
Regards
Leecka

Hi,
I installed iMovie 10 when I first purchased the Macbook, but I deleted as I did not need it then. It was free then. However, I reinstalled Mac OS X after that.
Now, it is not free at all.

Is it possible to upgrade Oct 2013 MBP-r SSD how much before it slows down?

Hi all,
I was just wondering if its possible for Apple to upgrade the SSD in my macbook pro retina oct 2013 model,
I sorely wish that I had gone for the 256GB model really, I purchased applecare, so I don't want to void my warranty - besides, googling around I found out that there are no aftermarket upgrades available for it anyways.
I have set time machine backup to backup manually (is this okay?, I Don't tend to make mistakes of emptying unwanted stuff in the trash, or is it likely ill need to use it for more than this?)
Also, coming from PC's ive always noticed a considerable drop in performance once a drive starts getting alot of data, how much roughly does it take to slow down an SSD, is it the same as a spinny drive? Im still pretty new to OS X, first mac and first SSD and im panicking ive made a serious mistake purchasing such a small drive.
Thanks alot for your patience, I did have a search but im not brilliant at searching lol

Information for offloading data onto medium-speed and fast external disks:
Standard disks on Thunderbolt connectors are a waste of money (limited by the rotating disk speed at ~100 MB/s). Standard disks on USB 3.0 run just as fast as on Thunderbolt. You can use an external Seagate 1 TB hybrid SSHD to run at the maximum USB 3.0 and Thunderbolt speeds when accessing the 8 GB SSD cache.
Performance and price summary for Macs with USB 3.0 and Thunderbolt connections:
Expensive, Internal SSD, Many 100s of MB/s, 120 to 1 TB GB capacity
~$100, Standard disks on USB 3.0, ~100 MB/s, 1 to 3 TB capacity
(Avoid 4 TB disks. They are not as reliable.)
~$200 and up, Standard disks on Thunderbolt, ~100 MB/s, 1 to 3 TB capacity
(A waste of money.)
~$130, Hybrid SSHD on USB 3.0, ~100 to 200 MB/s, 1 TB capacity
($110 SSHD + $20 USB 3.0 enclosure)
~$210, Hybrid SSHD on Thunderbolt, ~100 to 300 MB/s, 1 TB capacity
($110 SSHD + $100 Thunderbolt enclosure)
"Seagate Backup Plus Portable Thunderbolt Adapter “
Expensive, External SSD, ~350 MB/s, 120 to 1 TB GB capacity
R/W disk speeds:
USB 3.0 and Thunderbolt about equal at ~110 MB/s
Firewire about 65% at ~60 to ~70 MB/s
USB 2.0 about a third at ~35 to ~40 MB/s
R/W SSD speeds:
Thunderbolt fastest at ~355 to ~370 MB/s
USB 3.0 second at ~165 to ~195 MB/s
Firewire third at ~60 to ~70 MB/s
USB 2.0 fourth at ~40 MB/s

MBP Early 2013 somewhat random but recurring kernel panic

Hi-I just bought an MBP early 2013 model. I've had it just over a week and have had 8 kernel panics. They appear to be happening when the computer is turning on - either cold (from being shutoff) or waking from sleep (however it doesn't do it everytime it wakes or boots). I've got all the software updates installed (excepting Mavericks...I don't plan on upgrading to it for a while). Here is the latest panic log. It appears to be something with the video card, but I'm a relatively new mac user, so I could be completely off. The video card it came with is the Intel HD Graphics 4000. I plan on taking it back to where I bought it to get it looked at, but I'm curious if you guys have any thoughts on it.
Thanks

It seems that your graphics card is causing the panics, or it MIGHT be your logic board (highly unlikely). What i suggest doing is running apple hardware test. to do this, shut down your computer and hold the D key on startup. If that doesn't work, try option(alt)+D, the rest of the process is simple

Reduced battery life for high-end MBP 15 2011?

I just bought a new MBP 15" 2011 model (2.2 GHz), an upgrade from my previous MBP 2009 (MacBookPro5,3; Intel Core 2 Duo, 2.66GHz)). I have noticed that the real world battery life is significantly worse than the previous model (3-4 hours vs. 6-7 hours). This doesn't seem due to the actual full charge capacity, since the MBP 2009 still has over 6000 mAh, whereas the new MBP 2011 shows around 7000mAh. Rather, it seems my MBP 2011 draws a lot more power from the battery than the MBP 2009. Could it be that the high-resolution matte screen is the culprit? FYI, the spec of my MBP 2011 is as follows (old specs in the parentheses):
1. 512GB SSD (256GB)
2. 8GB memory (4GB)
3. high resolution matte screen (1680x1050) (glossy standard screen)

If I remember rightly the 2009 units didn't have on the fly graphics switching?
The new ones do. That means sometimes you can be on the more powerful graphics card with out realising - this will kill your battery life. Wrote about it here for the 2010 models: http://www.markc.me.uk/MarkC/Blog/Entries/2010/4/21Early_2010_Macbook_Pro_-_Battery_LifePoor.html
There's a great piece of software that will allow you to control & see which graphics card you're on - I bet if you stick to the integrated graphics you'll see your battery life improve significantly.

A1281 is the battery i got for my 15inch MBP. Is the battery life only 2 - 3 hours for a new battery on this device.

A1281 is the battery i got for my 15inch MBP. Is the battery life only 2 - 3 hours for a new battery on this device.
This is from Apple.
2 to 3 hours seems very low.
what is teh standard or advertised spec for a 15 inch Macbook Pro with this battery.
I would like to know so that i can return it if this is not normal.
Its expensive so comments would be appreciated.

I say it depends on your model? average usage is about 3-4 hours depending on what you use and how you use it. Adobe Flash player eats a lot of battery power so if you are on a web page and has flash player, likely that it's eating up battery because of it's power thirsty.
Also check your systems activity monitor. It could be possible that one of your program/apps did not close right and may be still running. So check for that and end the process if necessary.
If you have a backlight keyboard, in a broad daylight, it's not necessary to have it on.
I also suggest that you use it plugged in most of the time, and it's not going to hurt or damage the battery if you have it plugged in all the time. Only use on battery if you are going to places that has no access to the outlet. If you are at home, then keep it plugged in. Just keep in mind to fully drain the battery until it your MBP turns off on it's own. This is the calibration process so that you have the most accurate battery readings.
The standard for 2011 MBP is 7 hours on battery. Before that model is 10 hours, but i don't believe that previous models will last 10 hours. Last week I calibrated my battery readings from fully charged and it took 9 hours to completely drain out the battery (I have a 2011 model),
If you think it's not normal and that your battery doesn't meet your expectation then set up an appointment with the genius bar and have them test the battery. They will determine whether it is faulty or not.

Retina MBP 2.6 only 3 hours of battery life?

My 1 week old Retina MBP 2.6 is only getting 3 hours max on battery with light surfing. When watching videos i also only get 3 hours tops. Bluetooth is off, keyboard light off, screen backlighting 50%, gfxCardstatus set to integrated only (also confirmed in energy saving settings). I run 10.7.4, all updates installed.
Is this normal? Isn´t it supposed to get at least 5 hours when browsing the web (no youtube)? Should i return it and get the 2.3 instead for more battery life?
Thanks in advance.

There have been reports of problems with various models experiencing low battery life after installing Mountain Lion but as you're still using Lion, you should be getting at least 7 hours on battery for light web surfing (not a lot of YouTube videos, etc.).
My suggestion would be to take the machine into your local Apple Store and let them deal with the problem. Before that you can download the free "Battery Health" from the App Store which lets you see your battery health in real-time, as opposed to always having to go into your System Report. There's no reason that you should be getting less than 7+ hours of battery life.

MBP early 2011 battery life

I have the early 2011 release of the 17" MBP (8gig ram, 2.2ghz quad i7, 500 gig harddrive) and it seems like the battery life has just been cut inhalf. It lasts me about 3 and a half hours from just general use. Is my battery faulty? Really appriciate any feed back

That battery looks pretty good, capacity is really strong for so many charge cycles, but the voltage looks low, would expect it to be in the 11.5 to 12.5 volt range and you are showing 11.27 volts. A little low but not critical.
How have you been handling that battery with respect to discharge/charge? While Apple has a lot of material talking about periodic deep discharge to shutdown and charge as a means of calibrating the battery, in reality that does not calibrate the battery itself. That only serves to calibrate the charge reporting circuitry built in to Lithium-technology batteries. In fact, the Battery University, an independent group testing batteries, has shown that repeated deep discharge behavior significantly shortens Lithium battery lifetimes. The optimum balance of use (discharge) and line-connection seems to be around 50% discharge before charge. Deeper reduces cycle life very fast, lower discharge makes for a very high cycle life but why buy a portable?
Anyway, just some thoughts. Use of high intensity applications, including other operating systems, looks like it is degrading the charge time but the battery itself looks healthy.
Just keep using it, perhaps try not discharging below 50% for a while and see how it behaves for your.

MBP 15" Retina Battery Life Problems

Hello all!
I recently got the highest end MBP 15" Retina and it runs AMAZINGLY fast, but the only problem I'm having with is the battery life.
For example, right now, at 100% charge, the predicted time is 4 hours and 35 minutes, but it's plummeting very quickly; I don't think I'll get more than 1 or 2 hours.
On the website, the average predicted battery life is almost 8 hours. I understand that the numbers on Apple's website may not be exact, but I feel like getting a quarter or even half of the advertised battery life suggests there is something wrong as well? o-o
I'm not doing anything intensive on my computer either; just simple web browsing and chatting on Skype.
I've searched the internet for solutions, and I've already tried resetting PRAM AND NVRAM settings, I've turned off Bluetooth, and checked off all of the Power Saver settings in Preferences.
My battery's condition is "Normal" since I recently purchased it.
I'm curious if anyone has a solution to this problem? (To give an idea of how fast the battery is draining, I started writing this post with 100% battery, and now it's at 98% several minutes later)
If anyone has any advice, it'd be greatly appreciated!
Thanks in advanced!

Skype is one of the most resource hungry application that one may use. It will drain the battery very quickly. When using it, connect your MBP to the power adapter.
Read the Apple hype regarding battery run time. The operative term is 'UP TO' not will achieve 8 hours run time. In the 'real world' conditions, battery run time will be determined by the number and type of applications you are using. If you are just text editing, you may very well get 8 hours from from the battery, but certainly not with Skype games or video.
Ciao.

Help with my MBP (Late-2011) battery life~

Hi All,
I just bought this MBP like 2 weeks ago & I found that the battery life is a little short.
Only lasted 3.5-4 hours. In saying that, I'm not doing anything extreme. Only browsing the web and doing some homework on Words & Excel.
If I happened to go on youtube or some video streaming site, the battery life only go as far as 2-2.5 hours.
Is this normal? I'm new to MBP & I'm loving every single bit of it.
I read the description on the website says the battery can last up to 7 hours.
I was wondering if my battery faulty or something? or is it just me?
I have turned down the brightness of the screen to about 40% and keyboard light is at about 20% (just estimate).
Turned off my bluetooth device. What else can I do to make the battery life last longer??
Any tips anyone can share with me?
Thanks in advance !!

If you have AppleCare, they will mail you the battery.
If you do not have AppleCare, call Customer Relations 1-800-767-2775. See what they can do for you. CS will determine if your model MBP qualifies for a free battery.
An Apple Store is not the only place to go. There may be an AASP closer. See KB Article: http://docs.info.apple.com/article.html?artnum=304398 How to find your nearest Apple Authorized Service Provider (AASP)
Another thing you can do is to go to System Profiler. Copy/Paste the Power info here. *Do not post any serial numbers.*

MBP Retina inconsistent UI graphics / battery life

I apologize in advance for the 1,000,000th thread on this topic. I (like so many others) have noticed very inconsistent smooth/choppy graphics performance with basic UI functions of OS X 10.8.2. I have tried a number of user suggetsions to alleviate this problem including turning off dynamic switching. That seems to have only a minor improvement, and kills battery life. I'm assuming that OS X (like windows machines) scales the CPU on a notebook to improve battery life. What I have noticed, is that if you have processor intense applications running/loading, the graphics lag (ie - dock zoom) improves dramatically. Has anybody else noticed this? This would at least suggest that the current retina MBP hardware components are more than capable of producing a smooth UI experience, in contrast to what other reveiw forums have suggested. Is there a way to modify CPU throttling at least when the device is plugged in? This whole issue is not a deal-breaker for me, but it's not what I've come to expect from Apple.

Update, for some reason puting the dock on the left or right side of the screen DRAMATICALLY improves performance of both dock magnification and the genie effect. This may be a software issue.

Quad Core MBP saving battery life by only using two cores

I am trying to use my MBP 8,2 with two of my four cores shut down in order to preserve battery life. Is this at all possible through 3rd party apps?

This whole thread reminds me of some of the nutty ideas American carmakers came up with during one of the first gasoline shocks back in the 70's. Don't remember whether it was Chrysler or GM, hellbent on keeping their huge gas guzzler engines, came up with the idea of disabling one or more cylinders when "not needed". A totally Rube Goldberg-ian contraption ensued, more prone to failure than any potential gas it may have saved.
And while on topic and following Señor Grant's lead, last Wedneday decided to take my MBP to the edge. 8% battery charge remaining, that is. That took the whole of 7:15, while running at 50% backlight, WiFi, MS Word and two browsers going (all four cores, too). Then on Thursday 10.7.4 + Safari 5.1.7 came out. So, back to the drawing board on Friday. 7:20 and 6% remaining, got tired of waiting and all this mine is bigger than yours BS and plugged it back in...

2010 MBP battery life (and hot power pack)

Hi All.
2010 MBP here and I am finally getting around to troubleshooting very short - like 2 hour - battery life. The battery pack gets /very/ hot as well. I do let it run down to nothing once in awhile.
Supposedly (acconrding to experts on the list) the fact that the MBP gets /very/ hot to the touch on the bottom is not an issue based on the specs I posted (I forget the name of the software I used to generate these specs).
Can anyone help me with whether I should bring this in or if there is anything I can do to troubleshoot this further? I basically can't take if from my office to the living room without bringing the charger which is sort of annoying.
Can anyone offer this new mac user any help while I reasearch this further...?
- Jon

best bet is apple store. they will help you fix the problems you are having with your mac. It may also help if you don't run intens applications which use a lot of CPU and RAM. also running a lot of apps at once drains battery and strains the computer. Macs tend to get hot because of the aluminum, but it keeps the internal components cool. Battery life, I cannot help you there. Let me know if that was helpful
