Short Battery Charge Life on My Nano!!!

I love my Nano, but I'm dismayed by how short the battery life is. Both the specs and the MacWorld test agree on 14 hours as the duration before it runs out of juice; mine won't go half that long. I've done everything I can to minimize battery use; I only play music on it.
All advice very much welcome. Is this a warranty issue?
Thanks in advance,
Bernie

Firstly, fourteen hours is the time it will run under
perfect conditions, with no button presses, no
backlight use, no track skipping, no EQ and medium
level volume. Real life use will be less.
Secondly, the vast majority of people who say their
battery is running out are going by the meter. Most
of the time, their battery hasn't run out at all,
they just think it's about to.
My ipod will play for five hours after the battery
meter has reached zero. The meter is very
innaccurate, especially when your ipod is new.
Ignore the meter completely. It becomes a bit more
accurate when you let the battery run out (for real)
and you only need to do that once in a blue mood.
Lithium-ion batteries take a while to come up to full
strength when they're new.
Switch off the backlight - it's still easy to read
the screen in most lighting conditions. Or at least
set it to 2 seconds.
But whatever you do, ignore the meter.
I will agree, yes they do take a while to come up to full strength, but this stuff about limited # of charge cycles is crap and stupid, that's basically telling the consumer "hey we designed the batterys in the product your about to buy to have a certain amount of charge cycles, then they are done so we can take your hard earned $60.00 and give you refurbished junk, because we are a company ran by apes!!!!

  • Nokia 6133 - battery charge life

    Hi all,
    First post here. I have noticed that my new Nokia 6133 has a very short battery charge life. I already did the usual 3 full discharge/charges and was now expecting it to last several days. I charged it yesterday, logged 20 minutes of send/received calls, one received e-mail msg and the battery is now less than half charged. Also, I have the screen savers off.
    Are there better batteries available for this Nokia 6133 model?
    Thanks,
    JPRola

    eew, reading: I read your comment, wherein you sounded rather irritated.... how could somebody ask such a stupid questions does he know nothing about computers? You are right I am no computer geek - just a simple user who loves the Mac.

    Hi Josh,
    Eew, myself and many of the other "regulars" respond to thread identical to yours on a daily basis. There are hundreds of threads started in the past 90 days where the first post is pretty much identical to yours: "So Apple advertised 8-9 hours but I'm not getting it, why?" Even looking at my own posting history, I've responded to 46 threads with this same theme since June 1st. So while I can't speak for eew, I understand his perceived frustration.
    Your battery life is going to vary based on usage, as I'm sure you know. I can routinely get 5+ hours of light usage on my new machine but if I tax it then I can easily drain the battery in about 2 hours, sometimes even faster if I really wanted to prove a point.
    As for "sales gimmicks," at the end of the day Apple is in the business of making money. If them advertising super long battery life is what allows them to move units then they're doing it right. If you're not satisfied with your product, you feel it may be defective or doesn't work as advertised you're more than welcome to return it, ask for an exchange or request that the unit be serviced.

  • Low battery charge life?

    I bought an iPhone4 a couple of weeks ago and though obviously busy on it initially I recently noticed, with more 'normal' use, how quickly the battery runs down. As a test I've had wi-fi/networks off for a couple of days and generally it's 'sleeping' a lot but, for example, it"s lost 35% of its charge in 6 hours since fully charged.
    What should the 'average' charge life be? Surely more than that?
    Oh, and I see no-one has any ideas about my Youtube question in this topics list...?

    It all depends on what you do on your iphone during those 6 hours. But it sounds about right. None of the 4 gen iphones I've owned have been able to keep a charge for an entire day without having to recharge it at work or in my car. I do use it for everything- music, games, surf the net, etc... It's a downside to all smart phones and the iphone is not an exception.

  • Relatively short battery charge

    I have a mid-2010 Macbook Pro 15" 2.53 i5. It was purchased in July, but I just received it (second hand) last week.
    Works great- with one exception- the battery charge. I get, with a full charge, 4 to 4.5 hours. The only programs running are Google browser and my email. I check the CPU usage, and both are listed as less than 10%.
    I re-calibrated the battery. Turned off bluetooth. I have all the energy settings optimized. Same 4 to 4.5 hours.
    As I type this- I have 96% of the battery remaining and 4:28.
    CoconutBattery says current capacity is 7002 and design capacity is 6900. It does fully charge to the 7002.
    I would not expect the advertised 9 hours- but would expect 7-8 with regular use.
    Seems like I have exhausted any software issue (unless someone else has a suggestion).
    Is this something that should go to an Apple support? Could it be a hardware issue?
    All else with the Macbook looks and works great.
    Thanks

    Thanks for the above. I did several of the things and ran some experiments.
    I loaded gfxcardstatus and set it to "intel only" when on battery. Bluetooth is off.
    I closed every program, and with every program closed and the macbook sits still for a few seconds- my battery goes up to 7.5 hours. Fine.
    As soon as I open 1 program- first was Safari (per the suggestion)- it drops right down to 4.5 hours stays in that range.
    Then I close Safari and it eventually goes back up to 7.5 hours.
    Then try Google Chrome. Back down to 4.5, then back up to 7+ when I close.
    Same thing when I open other programs. Outlook, etc.
    Now of course, to lose battery power capacity when having a program open seems normal- but to drop 3 hours worth (almost half) with only 1 program open seems odd to me.
    Normal or unusual?

  • Very very short battery life - will not hold charge on new ipad mini retina, HELP

    My iPad mini retina OS7 will not hold it's battery charge. I have turned off Location services, do not have apps running in multitude task mode and do not have Bluetooth on.  I close  all aps and the smart case and come back in an hour and find charge will still have gone down  10 to 30%

    Some ideas.

    Otherwise if they don't help take it to an Apple store if possible, they should be able to confirm if the battery is worn oout or some other fault.

  • Is it bad for the battery if i leave my nano 5th on the charger all the time?

    Is it bad for the battery if i leave my nano 5th on the charger all the time?

    No, it's actually what you're supposed to do. To prolong the battery life, try to keep its level high or full as much as you can.
    I don't know for sure, but I think the iPod does not draw current from the charging battery but from the charger itself.

  • The cause of the whine, heating and short battery life.

    It seems like we've discovered how we could fix the whine, heating and the short battery life.
    If you take a look at /var/log/System.log
    You will find this line:
    localhost configd[37]: com.apple.SystemConfiguration.DynamicPowerStep load failed
    Yes, that's right. Intel SpeedStep is not implemented in Mac OS X.
    It seems like Apple wanted to implement it, either the engineer in charge of it was screwed up or apple was hurrying to get macbook pro released...
    This also explains why Macbook pro has a higher battery life, runs cooler without whine on a properly configured Windows XP (with updated intel drivers and microsoft hotfix). On Windows XP, when the system is Idle, CPU is throttled to 1GHz.
    So we have two options:
    1. Get Apple to implement it correctly - but so far it doesnt seem like apple is really concerned about this issue. Or rather, they don't seem to care.
    2. Implement it ourselves - A guy called Cryptonome was trying to implement the proper power management for MacBook Pros on Mac OS X to solve these "CPU whine", heating and battery life problems, and he did have some fruitful results, but it seems like he's currently too busy or something to finish the implementation.
    Unfortunately I am not a genius so I cannot implement anything like this... anyone?
    What do you guys think?

    That's exactly what I am doing : expecting a solution from Apple. And you know what, Apple today released a new system update for the keyboard. This update is for all the MacTels including MacBook Pro. And guess the next thing... This update fix a power draw in the MacBook USB... Great... Oh, no, in fact not so great because this bug is THE bug that allows to stop the whine (through Mirror, etc)...
    Is there anyone in Apple that tests fixes before to release them ? Do those engineers working on the whine fix have given a look to that patch ? I really hope that Apple is doing something, but releasing this Keyboard patch for MBP now can mean 3 things (IMHO) :
    - the whine patch is on the final steps and will be released soon, so killing the workarounds for the whine is not a problem,
    - or Apple has a partial (or even none) knowledge about this problem, and they should hire better engineers, because many people made a lot of discovers about this whine, not beeing engineers,
    - or Apple definitly doesn't care about this whine problem, and they will loose myself as a customer (and probably others).

  • Short battery life

    hello
    I have arch with gnome on my Toshiba laptop and i have very short battery life.
    it ends after about 40min.
    it seems to be problem in the system because when i open the computer it told me it have about 2hours and i put it on friend's laptop with vista and it told me i have 92% and 1:10hours left so i think there is(are) any or some process(es) that waste power and so short the battery life.
    how can i manage the power consumption and by that to maximize battery life?
    10x anyway
    ariel

    For starters, dim your display backlight.  Set the system up to make it happen automatically.  Have the shut the backlight off after more than a few minutes of inactivity.
    Throttle your processor(s).  Set up cpufreq and configure it to use an aggressive governor while operating on batteries.  On laptops, you should also enable a governor such as "On demand" to help keep the system cool even when running on AC.
    Don't do things that draw power.  Try not to use the optical drive.  If you want to watch movies, rip them to the hard disk while on AC, watch them from disk while on batteries, and delete them when you are done.
    Look into the power management of your hard drive.  You might look at allowing it to spin down when inactive, but I find this to not work real well under Linux.  They tend to spin up and down a lot, negating the power savings.
    See if you can shut things down.  Wireless transmitters use a fair amount of power.  So do the receivers while they are doing correlation (trying to synchronize to the chipping a spread spectrum channel).  If you are not using wireless, shut it off.  Look into whether your laptop can shut off other systems it is not using.
    Minimize USB devices.  They draw power from the system -- especially ipods and cellphones which charge their batteries from their host.
    Laptop manufacturers spend a great amount of effort customizing certain operating systems from the American Pacific Northwest to maximize the battery performance of their systems.  It can be expected that Linux require a little effort to optimize for power management as well.

  • Has anyone encountered drastic shorter battery life both on iphone 5 and ipad since updating to iOS 6.1.2? How can this problem be solved?

    Dear all,
    I am new to this community even though I have been a Apple user for years, so please forgive me if this question is not in the right section.
    Has anyone encountered drastic shorter battery life both on iphone 5 and ipad since updating to iOS 6.1.2? I've always been happy with these two products until the update - now the battery life is considerably shorter which is extremely frustrating.
    How can this problem be solved? Is there any way to go back to the previous version?
    Thanks for your help.

    If you update using iTunes the phone is first wiped clean, then the new OS is installed, and finally the backup is restored. After this finishes if you sync your music should be restored. Music is not in the backup, because it is already on your computer and duplicating it would use up a lot of hard disk space.
    An OTA update just patches what has changed; it does not disturb content.

    To keep track of the battery charge and condition go to Apple Menu/System Preferences/EnergySaver and check the show battery status in menu bar.

  • Possible work-around for v3.0 short battery life

    First: be aware there's a difference between "Push" (which is for some email account types & some MobileMe features) and "Push Notifications" (which is for apps). They are controlled in separate Settings screens.
    Short story:
    If you've upgraded to v3.0, usually have Wifi ON, and experiencing short battery life, and if you can live without Push Notifications (at least until Apple finds a better solution), TRY TURNING "Push Notifications" OFF.
    Alternatively, if you can live without Wifi but need Push Notifications, try turning Wifi off & let the data travel via 3G.
    Long story:
    First I ran alternate days with Wifi ON, then Wifi OFF, and noticed with Wifi OFF my battery life was nowhere near as short (I could get through a day), but with Wifi ON, I can barely get through half a day. This is very different to v2.21, and in my setup the only significant difference was Push Notifications being ON.
    Then today I've been running continuous pings from my Mac to my iPhone, with various combinations of Push on/off, Push Notifications on/off, email accounts on push / fetch / manual, and discovered there's a huge difference in how often Wifi gets turned on when Push Notifications is enabled.
    With Push Notifications ON, while your iPhone 3G (and probably 3GS) is asleep, Wifi will be turned on for 15-20seconds every 1 to 2 minutes!
    This is in stark contrast to Push Notifications OFF, but Push (for email, MobileMe, etc) ON, where Wifi is on only as often as your email account settings dictate.
    This explains a lot, I think. With Wifi OFF, data goes through the 2G/3G radio, which is inherently ON all the time (for phone functionality), so the incremental 'cost' (to battery life) of Push Notifications is comparatively small.
    But with Wifi enabled, data is instead sent via Wifi. The incremental cost (to battery life) is dramatically higher having to turn on the Wifi radio, find the WLAN, get an IP from DHCP, then exchange data with various Internet servers, when it happens every couple of minutes!
    Though I'm not really sure what Apple can do about this situation. They appear to be turning Wifi on frequently to give the illusion of true (ie timely) push notifications. I think this situation runs parallel to those who found, with v2.x, that enabling Push on email accounts & Wifi enabled had similar major negative impact on battery life. Except now heaps more people want the Push Notification feature. Interesting conundrum...

    The main thing that helped me with the short battery life was lowering the brightness. My 3G was so bright I could'nt sleep at night.

  • When I got a new iPhone5, I experienced short battery life, and system sofware issues were not the cause. The camera also takes a blury picture regardless of lighting and I have the black one. Has anyone else experienced similar problems?

    What makes you so sure it isn't software?
    The camera can be focused by take the point of focus on the touch screen.
    If it is new as you said, it should be under warranty. Make a Genius Bar appointment or contact Apple with a repair request.

  • My MacBook Pro is really hot and the fan is on constantly. It didn't use to do this, does anyone know why this is happening? I have a very short battery life, so I have to keep it plugged in probably more than I should.

    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
