Estimated Battery Life

I just unpackaged my 13 inch MacBook Pro and re-calibrated the battery (drained battery and recharged). It still shows about 3 hours on the battery icon which is what it showed prior to the re-calibration. Given the reports of up to eight hours of battery life I was expecting to see a much higher estimate. Is this normal? Any feedback will be appreciated. Thanks.
My battery profile looks like this:
Charge Remaining: 5718
Fully Charged: YES
Charging: NO
Full Charge Capacity: 5768
Cycle Count: 3
Condition: NORMAL
Amperage: -2225
Voltage: 12145

Battery life depends very much on what you're doing with the system at the time. Apple's estimates are generally going to be pretty optimistic. Like what you'd get if screen brightness were at it's minimum, the system was just sitting idle, doing nothing at all, and every possible power saving trick had been employed.
The more parts of your laptop are active however, the more power they draw, and thus the faster the battery drains. So, battery life figures are never reliable. One person's experience will never match that of the next.

  • 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.

  • Battery life on Macbook Pro (3 hours?)

    I just got this laptop. It's a 15.4" MBP. I installed Snow Leopard on it from the upgrade DVD (from Leopard). All is well, but the estimated battery life is around 2:30 - 3:30. I've had the battery on charge for days and the button on the left of the mpb indicates a full charge.
    Is it some services that are running? Is the estimate just way off (I know they usually are)?
    My brightness is 3 blocks from full. I have iTunes (playing), Terminal (no activity), Adium, MacVim, iCal, Firefox running. Does this sound accurate?

    i have a unibody late 2008 w/c lasts about 2Hrs+ or 3Hrs max. is your macbook pro the built in battery?early 2009 and mid 2009 model?if so that doesn't sound right since the built in battery have 7hrs battery life "ideally" but reality its just 4-5hours. I've tested 3 of them already and all have same behaviors.(2mid 2009 macbook pro and 1 early 2009 macbook)
    Airport: off
    Bluetooth: off
    Brightness: 2 bars
    only running: safari and quicksilver
    no external device plugged in
    no CD inserted
    have the latest battery update and firmware update
    so yeah not a bug not an issue with battery but that's just how it is. Macworld already did some lab bench test on their own and so did the other mac fanatics. I just don't get why sometimes Apple says it will last 5hours if it won't.

  • Question about battery life

    Hi everyone,
    I got my refurbished MBP 13" mid 2010 model two Friday's ago (July 16) from the Apple online store and I have some questions about the battery life....
    Immediately after I got it, I followed all the battery calibration instructions from apple.com/batteries (and did it again after it because I was unsure if I did it properly). While it was charging, I was installing some recommended applications, one being coconutBattery. In the additional information section, it said that my MBP was 7 weeks old, has gone threw 10 battery load cycles, and had a original battery capacity of 97%. I am now at 17 loadcycles, with 94% original battery capacity.
    Now to how much time I get with the battery... I have done some testing of my own, such as watching some movies (Tron and Star Trek First Contact, I'm a geek :D), basic web browsing (5 tabs open, reading blogs, watching a couple of 3 minute youtube videos) and listening to an audio book (iWoz) with a tab or two open. The best battery life I have gotten (basic web browsing) was 5 1/2 hours, with 60% LCD brightness, keyboard backlight off, and bluetooth off, with just Chrome and coconutBattery open.
    Is this the average battery life for everyone else? I bought this because of its supposedly good battery life, and though I am very happy with my purchase, I just want to make sure that I have a fully working MBP.
    Some other notes:
    The battery meter next to the clock sometimes says that 98% is fully charged (I think it is just a glitch)
    The estimated battery life is between 9-11 hours when brightness is at 30%-40%, airport and bluetooth is off, and keyboard backlight is off when I am doing text editing.
    Thanks in advance.
    EDIT: Forgot to say I have the 2.4ghz 250gb model.

  • Poor 4S battery life while using apps

    Most of the posts I've been following about cruddy iOS5 battery life seem to revolve around when the phone is in standby. I seem to have that mostly addressed on my phone. So my big complaint is how poor the battery life is while I'm actually using the phone. I'm coming from the 4, whose battery life wasn't really stellar, but this is by far worse.
    I know they dropped the estimated battery life on WiFi from 10 hours to 9, but what I'm experiencing is worse than that. I played 10 minutes of a non-intensive game yesterday (one that wouldn't have a large battery impact on my 4), and in those 10 minutes, the battery life dropped from 75% to 69%.
    As of right now (12:31), my battery life is at 22%, down from 76% at 6:30 this morning. With my 4, I would have been in the mid 50s, and I've done nothing differently than I would have a week ago. Checked my mail, read a couple of static pages in Safari, messed with the Settings a little, checked my calendar and reminders a couple of times--nothing intesive. No games, no map. I did browse the App Store for about five minutes, but... This is all standard usage sorta stuff that never would have drained half the battery life with my 4. My "usage" even shows that the phone has been inactivate for 3 out of those 6 hours.
    Any suggestions on this? My standby life, while not fantastic, isn't horrific, so I think I've effectively tweaked a lot of the tweakable things (like location stuff, diagnostics, etc). But is there something I could be missing? I have the screen on auto-brightness with the slider set to just below the "gh" in "Brightness." That's where I kept it on my 4, too.
    I thought I read the new battery was actually better, but this is definitely not an improvement

    I have the same problem! Mine does last for about 3 - 4 hours, but that is about it! Any suggestions?

  • Estimation of battery life

    Hey
    gnome-power-manager doesn't show estimated time in hours:minuts, only in percentage, when it's discharging. When I used KDE the power manager showed hours:minutes fine.
    I know gnome-power-manager works on this laptop since it worked with Ubuntu.
    Anyone have a fix or is it possible to use KDE's power manager in GNOME?
    Regards
    Casper.

    KDE's power manager wont look nice in the gnome bar. Look for another gnome battery life applet or check the preferences of the applet.

  • 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)

  • What is average battery life everyone is getting for the Zen Mic

    I just got my Zen Micro last Thursday. I'm concern about the battery life. I haven't fully tested the battery yet, but I'm estimating that I will only get about 6-7 hours for it. The advertised time was suppose to be as much as 2 hours. Now I know that depends on your usage (e.g. volume, bitrate of the file, play mode, etc.). What are other people getting? Thanks.

    My last test, I tried to be as natural as possible. That is: back light is on; shuffle mode is on; eq is on; volume is normal (at 4 to 6); I skip or go back to tracks; I fast foward; the contrast is at 50 percent; average bitrate (from 28 to 360); smart sound off; and other minor things that I can't remember. That test gave me only 7.5 hours.
    I think that is pretty modest usage. Any average mp3 user would do the same thing. Yet, I only got 7.5 out of the possible 2. I don't like the sounds of that.
    I'm running another test right now with the same conditions above, and I'll let you guys know what I get.

  • Why doesn't dimming my screen affect the estimated battery time remaining?

    rMBP 15". The brightness of my screen greatly affects the battery life. At near-full brightness it will discharge from 100% to 20% in about two hours. At the lowest brightness setting, it lasts between four and five hours. However, when I click the battery icon and hold it down, the estimated time remaining doesn't change regardless, despite the obvious and significant difference between the two brightness settings, all other things being equal. Is there something I can do to make this estimate more accurate?

  • HT1435 During normal charging phase is there a way to see the estimated battery% ?

    A1285 (EMC 2287) iPod nano 4th Gen
    During normal charging phase is there a way to see the estimated battery% ?   If I am at 10% and plug in to charge and it takes 30 minutes to get to 55% then I know there are about 30 more minutes of charging until I'm at 100%.

    There is an App at the App store called "Battery Magic". You can get a trial version, (free) that will show you what you want to know, including battery life, and how long you can play games, music and other things on your current battery life.
    You can also download the full version. I think its $0.99.

  • Battery life suddenly cut in half

    just yesterday, during my first class, i noticed that i only had about 2 hours left on my battery-- this was just about 15 minutes after unplugging my fully charged macbook. the same thing happened today...i don't know what's going on, i used to get around 4 hours with it. i haven't changed any habits-- i dim the screen as much as possible, etc.
    i'm calibrating the battery right now...will that work or is something else wrong?

    Hi,
    Macbook battery life arouse lot of feedback. My experience is after re-calibration the total capcity of battery losts at least 100mAh. But if just connect to internet via airport, still I can manage to use it with over 3hrs. But when I run photoshops or bigger size file, the time shown on menu bar dropped tremendously to 1:50hr somethg from 3:03hr. But this battery seems to last quite good at last few %. My experiences on powerbook G4 1G, with 1.25G DDR ram, when battery drops to 10% or 10 minutes, the Powerbook will go to sleep soon. But for Macbook, when the indicator shows 0:09 hr remained, if using for internet it can still last for more than 15minutes. I also asked Apple HK technician about the battery drop problem, they said this is just rough estimation, sometimes not accurate, and it is normal that battery sometimes can't charged back 100% full unless after recalibration. If ur cases after full charge, check if ur battery is 100% or below 90% uisng coconut, Apple said if under warranty the battery drop below 90% for full charge, u can replace the battery in Apple repair center. This is the case in HK , I am not sure the practise in ur country.

  • Macbook Pro (Non-Retina) Battery Life

    Just recently purchased a non-retina MacBook Pro, 13" with the upgraded i7 processor.  So far, it's lots of fun, just one small question/concern...
    Does the battery life really suck on this one, or is it just mine that possibly needs service?
    The estimated remaining battery time keeps fluctuating, which is understandable, which attempting to constantly calculate; however, I score perhaps three hours of life using only web (Safari) and iTunes (transferring songs to/from iPhone, etc.)  I haven't even installed my Adobe CS collection yet, and I'm afraid it'll constantly be glued to the wall adaptor, thus defeating the purpose of an expensive, beautiful laptop.
    Anyone believe this to be common, uncommon, or bizarre perhaps?  I've got AppleCare, of course, so worst case scenario, I create a TM backup and send in for inspection/repair

    There is an authorized Apple store not far from me, but I've only seen one technician there ever, and they'd most likely send it out for service or something anyways.
    Any web browser I have attempted to use (Safari, Firefox, and especially Chrome,) is listed under "Apps Using Significant Energy.." though Firefox and Safari have only stated that when more than one tab is open, doing searches.  Chrome states that upon opening the app- weird.
    There is no constant video streaming, only videos on occasion, likely via YouTube; all that's one with iTunes is syncing with the external hard drive that houses the files, backups, and playing music- no iTunes Radio, Podcasts, or of the sort.  Also, iTunes (almost) never shows in the Significant Energy column- only seen it there maybe once.
    When using the computer, I see the calculated battery life jump from seven, to five, to three something... which reminds me more of my ancient PowerBook. haha.  There has been nothing done so far other than small, meddling tasks- non-significant sized file downloading, occasional video, and the bulk of it just retooling the iTunes library- still restoring it from scratch
    I just want to be certain that there's no significant energy usage hidden here.  This machine has the 2.9ghz i7, with maxed 16gb RAM- would that differ anything from the original spec models that people test and claim to have some solid battery life? (I don't mean the new Retina or Air models)  It seems fine when I unplug it from the wall, but drains quicker than expected.  Once I start drawing and editing, I'd like for this machine to last more than an hour

    ok, I will tkae that under consideration. Now I have another battery issue, after fully charging the MP3 player I noticed that the battery life drain rather quickly while it is off. I lost 9% of it's charge from taking it off the charger at midnight and then plugging it into the usb port of my computer the next morning at 10:00am. The clock is turned off so it should not be doing anything for those 0 hours.

  • Is it normal for iPhone 4S to lose 1% battery life after 2-3 minutes of using?

    Is it normal for iPhone 4S to lose 1% battery life after 2-3 minutes of using? So in 2 hours, 24 minutes usage and 15 hours, 17 minutes  in standby mode, the battery became 68%...

    sounds plausable
    also you can't really 100% trust it's batt% batteries are an analog technology the only thing the iphone can judge how much batt is left is by measuing amp amount the batt is producing and then over time estimating how long before it's zore
    but anyway Its not wise to not put a battery for charge before bed when it's 12%
    if your reason is you think it's good for batteries to be empty before charging then you believe in a myth and in the process damaging the battery in your ios device
