SR MBPs... Real Life Battery Usage

I'm thinking of getting a new 2.2 MBP. Has anyone done any real life battery tests on these yet? Now that they have LED displays, etc. Anywhere near the battery life of the regular mac books? What kind of battery life can you expect if you turn off bluetooth, the backlit keyboard and the screen brightness at 3/4 from max? I'm coming from a 12" PB.
Thanks!

From what ive seen alot in these forums, it doesnt seem like the LED lighting makes a huge difference in battery life: only a very small one.

  • The real world battery life of a 2013 MacbookAir ?

    Here is my situation. I use my Air a lot in the field (photography, and a few other things). It is the model before the 2013.
    My question is, is the battery life of the 2013 model as good as it is said to be? I read reviews which say 7 hours or more of battery life, in real world conditions. This is a lot of time, a game changer.
    I am definitely considering buying the new model, but only if the battery life is significantly better (my current Air is only a year old). Can anyone who used one of these fine machines give me their thoughts? Is the battery as good as claimed, is the battery life ok (I have read that the new batts have a shorter life span).
    Any advice appreciated.

    is the battery life of the 2013 model as good as it is said to be?
    I get 12+ hours out of mine, it depends on what you are running as the main factor
    compared to my 2012 model I sold, the improvement is a bit stunning.

    I read reviews which say 7 hours or more of battery life
    Again, that totally depends on WHAT you are running, ..videos, a good bit less
    Ive owned 3 Air, the battery life on the new Haswell is incredible, far better than last 2012 model, as apple.com chart will indicate to you.
    Youre not going to find another superslim notebook/laptop with this power that does it all with THIS kind of battery life.
    Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
    And best "tip" is if its near a socket,...plug it in as long as you can (especially at home) since cycle count on the battery are the "miles that wear out the tires (battery)", however again, not plugged in all or most of the time.
    http://www.apple.com/batteries/notebooks.html
    "Apple does not recommend leaving your portable plugged in all the time."
    While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
    *A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge. 
    DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count.  *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
    (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
    *Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
    *However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
    Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”. This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
    LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
    A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
    Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
    The only quantified abuse seen to Lithium cells is instances when often the cells are repeatedly drained very low…. key word being "often"
    The good news is that your Macbook has a safety circuit in place to insure the battery doesn’t reach too low before your Macbook will auto power-off. Bad news: if you let your Macbook protection circuitry shut down your notebook at its bottom, and you refrain from charging it for a couple days...the battery will SELF-DRAIN to zero (depending on climate and humidity)…and nothing is worse on a Lithium battery being low-discharged than self-draining down to and sitting at 0
    Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
    Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.

    Storing your MacBook
    If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.

  • Usb2 in specs but 12 Mbps in real life ??

    Hello,
    I own a 2004 iMac flat panel (20", 1.25 GHz G4, Mac OS 10.3.9).
    In the specs, it's supposed to be equipped with three usb2 connectors.
    If I go to the system information, 2 buses are said to be limited to 12 Mbps, and a third one is said "high speed", but never shows any device.
    The mac is connected to :
    1. a Canon Pixma MP110 printer (officially usb2 High Speed, but 12 Mbps in the sys info)
    2. a usb hubb (leading to Apple keyboard and logitech wireless mouse)
    3. occasionnally to a digital camera or a iPod nano (and hopefully, if this problem is solved, to a usb2 camcorder in the future). All appear in the "normal" 12 Mbps usb listing in sys info.
    How to get the advertised 480 Mbps usb2 ?
    Thanks,
    iMac G4 1.25 MHz 20"   Mac OS X (10.3.9)  

    USB doesn't encrypt data. 
    USB 2 (High Speed USB is Apple System Profiler) is designed at 480Mbits per second which is 60MB per second. This real life this turns out to be a burst speed that the design of the protocol cannot sustain for long periods. There are overheads in the form of digital coding that will reduce this theoretical maximum too
    USB1.1 (The type built in to older Macs) is designed at 12Mbits per second which is 1.5MB per second. Again overheads will be seen on this protocol. The USB Developers reckon upon you getting about 0.9MB of bandwidth.
    (click to enlarge)
    The first image shows how ASP lists that I have 4 USB connections only one of which is High Speed. The second image shows the USB2 (green dots) devices I have connected and the Red bars show the physical USB2 connections I've made.
    In conclusion ASP is not an accurate list of the true USB hierarchy. This is probably due to their being spare USB buses in the iMac for Airport, bluetooth and modem data connections (not sure which though).
    I'm not sure why your printer isn't listed as USB2 (mine says 480Mbps) but other than that all is normal - you aren't been shortchanged. All actual USB2 devices will be listed under the one High-Speed USB heading when they are in use.
    I would recommend getting a Firewire connected DV Camcorder if possible as Firewire is a better protocol from Digital Video and Firewire plays nicer with iMovie (which is what I suspect you want).

  • Like to see few real life usage of Binary Tree C#

    whenever we read something about BTree then this kind of program shown in article with code.
    code as follows.
    Main File
    static void Main(string[] args)
    //Creating the Nodes for the Tree
    Node<int> tree = new Node<int>('6');
    tree.Left = new Node<int>('2');
    tree.Right = new Node<int>('5');
    Console.WriteLine("Binary Tree Display");
    Console.WriteLine(tree.Data);
    Console.ReadLine();
    Node Class
    class Node<T> where T : IComparable
    private T data;
    public Node<T> Left, Right;
    public Node(T item)
    data = item;
    Left = null;
    Right = null;
    public T Data
    set { data = value; }
    get { return data; }
    in our daily program where we can use btree to store and retrieve data? so please all share your idea how you guys use btree in your program in real life application development. thanks

    "in our daily program where we can use btree to store and retrieve data?"
    Given that your example mentions IComparable I suppose you're talking specifically about binary search trees, not any binary tree. In that case it's unlikely that you'll see anyone using a binary tree directly. People use collections such as SortedDictionary and
    such collections are usually implemented using binary search trees.
    Note that btree isn't a good abbreviation for binary tree, there is such a data structure called B-Tree and it's not the same thing as binary tree. Incidentally B-Trees are also used for searching - databases use them for indexes and filesystems
    use them to store directory entries.
    @Joel Engineer: "Binary trees structures are built into the Net Library Hash Class"
    Binary trees and hash tables have nothing in common.

  • Need help on real life usage of Aggregate functions

    Hi All,
    I'm preparing for 9i certification 1st paper and I'm now looking at aggregate functions. Could you somebody guide me to any link or source of information about the various various aggregate functions like CORR, COVAR_POP, COVAR_SAMP, DENSE_RANK etc. knowing the real life implementation would help me better understand those functions.
    Thanks in advance.

    Hi Charles,
    I'm having the same issue. If anyone answers my post, I'll let you know. If you remember, please let me know if anyone gives you an answer. I'm gonna try calling Apple tomorrow.
    All the best,
    Jimmy

  • MBP draining the battery very fast.

    My MBP 2011 is running out of battery very fast. I tried turning the Wireless off but still the same issue. This has been happening only for a few days now. Any thoughts why??

    Many users see Apple's "up to 7 hours" claim and figure they should be getting 7 hours no matter what. Nothing could be farther from the truth. How long your machine runs on a full charge depends very heavily on what applications are in use, what web sites are being browsed, and what settings are in effect on the machine. To get 7 hours, you must have all energy-saving settings optimized and be doing almost nothing.
    To maximize battery life in actual, real-life usage:
    If you have a 15" or 17" MBP, use gfxCardStatus to restrict your machine to using its integrated graphics instead of the discrete GPU.
    Keep your screen backlight turned down as far as you can stand.
    Turn off keyboard backlighting.
    Disconnect external drives, iPods, iPads, iPhones and all other bus-powered peripherals when running on battery power.
    Turn off Bluetooth and wifi whenever you aren't using them.
    Avoid web sites that have any Flash content, including advertisements.
    Avoid streaming any video from the web.
    Don't play any 3D games -- not even those that will run on integrated graphics.
    Quit all applications that aren't in active use.
    Close all web browser windows and tabs that aren't in active use.
    If you take all these steps, your battery will probably last around six hours. Of course you'll be quite limited in what you can do, but that's what it takes to maximize battery life.

  • Why does my battery usage and standby show as nearly the same amount of time yet I am not using my phone constantly ??

    Can anyone tell me why my battery usage and standby times are the same yet I am not using my eye phone all this time ? I am having real problems with my battery life it is running out after about 13 hours I have disabled most things suggested by other sites but to no avail !! Any suggestions ???

  • IOS 8.1.2 safari battery usage

    Ever since updating to iOS 8.1, my iPad battery life has declined to the point that i have to recharge every day.
    the only things i use my iPad for are safari, Facebook, google play books, stock music app, and youtube.
    I've checked battery usage, and safari has 90 percent of the battery usage.
    i have also factory reset the device, tried to keep screen brightness below 50 percent, and shut all apps, but that makes no difference.
    i have also updated to iOS 8.1.2, and it made no difference.
    am also considering a nexus 9

    i have same problem, than battery percentage jump from 60 to 45 e in this way my problem is very bud. ios 8 last update is installed on my iphone 5. i think that it is a bug software, and i think this because i called apple support and diagnostic realt time with operator say that my battery life is better. and after home button bug fixed with ios 8.1 now i have this. this ios 8 is the worse update ever. 

  • I'm trying to resolve a battery usage problem

    I'm trying to resolve a battery usage problem on my iPhone 5S ...
    Have been working with an Apple agent via chat and I'm 99% certain it's a software problem, but I can't isolate wish software ...
    So, I'm going to set up my iPhone up as new (when I did this as part of identifying where the problem is, it help its charge for 24 hours) but I have a problem with photos ...
    I can see photos on my iPhone (restored from an iCloud backup) up to date, but on my iMac/iPhoto with my iPhone attached i) I can only see photos on my iPhone up to a date in the past (mid October 2014) and ii) iPhoto says all photos have already been imported ...
    How can I (can I) get the more recent photos onto my iMac e.g. into a folder and then import them from there into iPhoto?
    Also, why is the restore from an iCloud backup taking so long (it's been 14 hours now) when I'm pretty certain everything's now there that should be?

    Just to add ... my real problem is that I can see photos on my iPhone, but in iPhoto with the iPhone connected, I can only see photos up to a certain date - weird?!!!

  • Does SMS relay iOS 8.1 cause extra iPhone battery usage?

    I was messing with both SMS relay the other day and noticed that my battery drained almost twice as fast..
    I was also messing with handoff and basically just testing the new integration features between Yosemite and iOS8.1
    But my question is about SMS relay.. Does anyone know if this will us up more iPhone battery than if I wasn't using SMS relay and just SMSing from the iPhone itself?
    Does SMS relay work via bluetooth? Could this be a cause for extra battery usage? It could be possible that I was jus using my phone a bit extra that day but I just want to make sure as I have SMS relay turned off for now, don't want battery life dropping..
    -Frank

    I had the same problem. I realized that it had everything to do with my calendar app. My iCalendar was having a difficult time fetching information from my Outlook and Yahoo Calendar. Causing my battery percentage to decline at a very rapid rate. (50% in a 4 hour time frame). I resolved the  problem by going into my Settings >" Messaging , Contact , Calendar" Setting > Clicking on one of my selected Accounts ( Outlook or Yahoo) and turning off the Calendar Sync. The problem seemed to go away after doing this. Now I'm only using 4% battery life in a 4 hour time frame in StandBy Mode. Well I Can only hope that this will help resolve the battery drainage issue. Good Luck ....

  • Still No Battery Usage Stats

    Hi folks, I've seen lots of posts on this but still haven't seen a good answer. I have had my iPhone since launch day. I haven't hacked it once. I've updated to 1.0.1 and 1.0.2 on the evenings those updates came out. My battery usage stats continue to say the following even after the battery charge indicator reads full-charge as indicated by the "plug" icon:
    Usage --
    Standby --
    Is this a bug? Or does this indicate a hardware problem? Am I too late to get a replacement?

    I've had the same issue since I fist got my phone. I called Applecare once and was told they are aware of the issue and it should be fixed in an update. This was about two days prior to the 1.0.1 release. I also visited the genius bar twice. First time I was told to do a software re-install. Second time they acted kind of clueless but checked a few employee phones and all we like mine, dashes only.
    Here is what I've observed, or my timeline on this issue:
    - After buying my phone and noticing this problem I went to the Apple store and the 4 or 5 phones I picked up all had usage meter stats. Genius bar was closed but someone helped me anyway and suggested a software re-install (this was prior to 1.0.1
    - When I went in for my second genius bar appointment I checkout out at least a dozen phones and all had "charing timer" stats. Both meters apparently counting up (hours charged) and both identical. This was after 1.0.1.
    If I do a restart while the phone is plugged in I get the charging timers instead of the dashes, but my phone acts up and once I restart again it goes back to dashes.
    I've got good battery life. Hopefully this will be fixed in an update down the road. Bottom line is there is a warranty on the phone so I'm just going to stop worrying.

  • Real Life Mac Mini Performance vs iMac

    Hi Guys, 
    I'm about to purchase my first Mac Mini, and I have question about Mac Mini's performance.  How is base Mac Mini compare against iMac 21.5 (i5 2400s) Base? I understand that iMac uses i5 2400s, desktop CPU, and benchmark number is obivously whole miles ahead of Mac Mini base.
    My primary use for Mac would be day to day computing with some Adobe web creative tools like Photoshop, In Design, Dreamweaver for checking web/graphic desinger's work.  I plan to study iPhone app development for fun, so some Xcode .
    I already have good 24 inch monitor,bluetooth keyboard and magic mouse from my last macbook pro setup.  Price difference between iMac and Mac Mini is about $500.
    In real life usage, with Memory upgraded 8gig, how much of difference would I notice?  Will iMac Base have significantly better performance ($500 difference)?
    Another quesiton is if I add SDD, will it void the warranty?  I understand that swapping HDD is okay, but I read somewhere saying that adding another HDD would actually void warranty....
    Thank you!

    I am an electrical engineer and do a lot of embedded firmware design
    and supporting software, mostly in Win8.1 virtual machine with Parallels.
    I also do a lot with Photoshop CS6 and some video work.
    When confronted with an upgrade decision, I ended up going with the 27" iMac
    and was glad I did.  Expanded it to the full 32GB and am using an SSD via Thunderbolt,
    I already had a Thunderbolt display, so I ended up with a very good workstation setup.
    With that 32GB of RAM, I am able to have OS X, a Win8.1 coding/debug virtual machine,
    and a Win7 software test platform all running at the same time and no noticable
    performance hit.
    Also, if developing large firmware/software, SSDs will speed the work up dramatically
    as these types of projects are quite file intensive.  The last project I was working on,
    I could build, download and start debugging an embedded app using Win8.1 on a VM
    before my coworkers were half way through building the app on their native Win laptops/desktops
    which had standard had drives.
    With that said, I still have 2 Minis in service.  My 2011 Mini Server (my former workstation) was
    repurposed to be my HTPC and my 2010 Mini has been re-assigned as my home iTunes/file server.

  • Ipad air 2 battery usage

    When i go to settings>battery usage> it shows that my home lock screen is using 84% of my battery. I have a photo that was taken with my phone as my background image on both. Do I need to change them out to a solid color to get better battery life?

    Hello fishes2000,
    From your post I see you're concerned about the battery usage on your iPad.  To learn what the Home & Lock Screen battery usage entails, please see the information outlined below.  After that is a link that can help you optimize the settings on your iPad to maximize the battery performance.
    Home & Lock Screen. This indicates that the Home screen or Lock screen was displayed on your device. For example, the display was awakened by pressing the Home button or by a notification.
    If an app frequently wakes your display with notifications, you can turn off push notifications for the app in Settings > Notifications. Tap App and set Allow Notifications to Off.

  • Upgraded to ios 5.1 now extremely poor battery usage any ideas?

    Upgraded Sunday to ios 5.1 now extremely poor battery usage - any ideas?  Have tried a few thinks - nothing seems to make a difference?

    Downgrading is not supported.  What IS supported is searching though the forums....there are a number of excellent posts with great suggestions on maximizing battery life and troubleshooting battery issues.

  • Top right battery icon does not show battery usage

    So over the weekend I did not charge my iPhone, because the icon always said I had full battery life. I believed it because I never made a call, listened to music/video or surfed the net. It basically stayed in sleep in my pocket both days.
    I get to work monday, pull it out to listen to music and I get the full screen battery icon showing the battery is dead with the plug and lightning bolt icons under it, then it turns off on its own. If I turn it on again, same deal.
    I get home, hook it up to my PC and charge it, it works fine.
    Today i've been listening to the iPod all day and surfing the net on EDGE and the battery icon in the top right shows full battery. To test I turned WIFI on for the past few hours to check and it's still showing full battery.
    Basically just the battery icon in the top right isn't recognizing the battery being used. My Usage stats in Settings are also blank for Time Since Last Full Charge.
    Background info:
    Refurbished iPhone bought directly from ATT, came with 1.1.1, immediatly upgraded to 1.1.4
    I've tried hard reboots.
    I keep push e-mail and WiFi off at all times. WiFi comes on very rarely and only for short amounts of time.
    I keep the phone connected to my PC overnight, but the PC does not go into any sort of sleep mode(ruling out not charging overnight)
    I'm going to go home tonight and restore the phone to see if that helps, but I wanted to see if this is hardware related or software. This just started this weekend and i've had the phone for a few weeks now, and other than some short battery life at the beginning when I would keep wifi and push e-mail on a lot, or the random Safari closings, no other issues.

    DOrk4L,
    Have you tried re-calibrating the battery? To re-calibrate it, let the battery drain completely and then charge it fully. You should see correct battery usage after that.
    Hope this helps,
    Jennifer B.
