Should I run my battery down?

Will the battery last longer if I run it all the way down on a regular basis?

No... Batteries do like variety though.

  • HT1632 My ipod seems to be stuck in a "Loop" as my nike+ tries to download, just keeps saying, "downloading" but nothing happens, runs my battery down. What can I do?

    My ipod seems to be "stuck" downloading of workout information to Nike+. Ipod keeps saying it is downloading but doesn't complete download, runs my battery down and my computer doesn't now recognize my ipod and I get "error" message (2005).  What can I do to fix this problem?

    I suggest try getting it back to your stock iOS and forget about jailbreaking.

  • Should I run my battery all the way down the first time I use my new Macbook Pro?

    I just received a new Pro. Is it better to let the battey run all the way down on the first use? Should I charge it all the way up and then let it run all the way down? Does either make any difference? Thanks.

    That is definitely not required.

  • My battery needs service as it is not working for long.  Apple claims it is not a defective battery and that it is my fault since I had the computer for 2 1/2 years and have only run the battery down to empty 100 times.  It is my fault because I did no

    Con't
    Apple claims that because I did not drain my battery frequently and kept it plugged in for extended periods of time, that it is my fault the battery is failing.  I disagree because I was not ever told to consistently drain my battery before recharging or not to keep it on and plugs in for extended periods of time.  I do keep my desktop computer on most of the time and that is why I have kept my Macbook air on for extended time periods.  I feel that Applecare should cover this battey issue and not charge me for replacing the battey.  I feel I should have been told to not keep my computer consistently running on with poweror the battery will fail.  Has anyone had this problem?  Apple should replace my battery under Apple care as my battery does not keep a charge anymore.
    I'll wait to hear.

    You said---Apple claims that because I did not drain my battery frequently
    You said---  I was not ever told to consistently drain my battery before recharging
    You should never do that on purpose, whoever told you that had it wrong or you misunderstood something
    Sure you dont have that backwards? thats exactly what you DONT want to do.
    Did you often drain the battery very low? that would explain a lot.
    Someone might have been misinformed about "battery calibration" regarding much older Macs with removable batteries (see bottom)
    You said-----I do keep my desktop computer on most of the time and that is why I have kept my Macbook air on for extended time periods.
    thats a problem there, youre not supposed to do that.
    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%.
    http://www.apple.com/batteries/notebooks.html
    "Apple does not recommend leaving your portable plugged in all the time."
    *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.)
    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.
    General rule to remember of Lithium batteries is:
    Never drain them LOW  & dont always/often store them HIGH
    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
    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 are instances when often the cells are repeatedly drained very low…. key word being "often"
    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.
    From Apple on batteries:

    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.
    Considerations:
    Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
    In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
    Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
    Ultimately counting charge cycles is of little importance.  Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery. 
    Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
    Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
    Peace
    Battery calibration, battery memory, battery overcharging, battery training, …all these concepts are mostly holdovers from much older battery technology, and on older Apple portable Macbooks ranging from early nicads, NiMh and otherwise; and these practices do not apply to your lithium battery and its smart controllers.

    There is no calibration of current Apple portable Macbooks with built-in batteries.
    http://support.apple.com/ht1490
    There is no battery calibration with current Apple portable Macbooks with built-in batteries. Lithium batteries have essentially a 0-‘memory’, and all such calibration involve the estimations fed to the system controller on the SOC (state of charge) of the battery over long periods of time as the battery degrades. The software based battery controller knows the battery's characteristics, or SOC and adjusts itself. This is why there is both no need and purpose to periodically deeply drain your macbook battery, since it doesn’t affect the characteristics of the battery, and further still deep discharges are something you should not do on purpose to any lithium battery.

  • Running the battery down

    Hi, is it correct that every now and then I should unplug my MacBook Pro and allow the battery to run down?
    Someone mentioned doing this at one time.
    Just curious.

  • Is it good to run the battery down on the Itouch til it shuts off?

    I have a habit of leaving my Touch on and letting the battery run down til it won't even turn on. Is this bad for the battery?

    It's good to deplete it once a month or so, but continual draining to zero is bad for Li-Ion batteries.

  • App running the battery down?

    The battery in my iPhone has started running down pretty rapidly in the last few days.  It could be the battery itself, of course, but I am wondering whether there is an app running in the background that is consuming a lot of battery power.  Could this be the case?  I know how to press the Home button twice to see the apps that are in the background.  But is there a way to find out which of the apps might be consuming a lot of battery power?  Thx

    I too have this exact problem - and I think it was occuring before I updated to 4.2.3.  Today I started with 100% power. It has been on charge via USB all day, but in the hour it took to get home, it reduced to 10%.
    Add to this, a lot of my apps are crashing - just shutting down half way through.
    - Facebook - just shuts down
    - SMS message - variably shuts down half way through messages.
    - Email - one of my accounts works, the other (work) stopped working on the 21/4.  When I go to Settings>Mail, Contacts, Calendars> and select the account, it just hangs, before shutting down back to the main screen after a couple of minutes. 
    In essence, my Iphone is completely screwed at this point in time. 
    I have done what was suggested about (Sleep + Home buttons) but no difference to the Email function (I can't disable it - it wont get in that far).
    BTW - it's a 3GS, and not Jailbroken.

  • Personal Hotspot  running iphone5 battery down

    My new Iphone5 seems to be stuck running Personal Hotspot without actually have any capability to enable or disable it, causing early drainage of the battery. has anyone identified a fix for it? Reading some comments by other users regarding the same issue on previous iPhone version indicated that Apple is aware of the problem and plans to develop a patch for it!
    Any guidance is greatly appreciated.

    Hi Kaz,
    Yes.  My hotspot works now, but a side effect of the strenuous troubleshooting endeavor my iPhone is now a little glitchy, e.g., cannot access my gmail account, and prompts me to choose a WiFi access point every time I try to access my emails. 
    As it turned out, there's nothing I could have done from my end to solve this.  I spent a long time with the Verizon tech support.  The tier 1 guy went through many troubleshooting procedures, told me to do various things on my phone while he checks how the system respond from his end, e.g., turn on roaming, restart phone, and etc.  After he tried his best to no avail, I was transferred to Tier 2 tech support.  He was able to apply scripts and patches to my phone and fixed my problem. 
    I don't recommend taking the phone to the Verizon store and expect any decent support.  I spent a long time waiting and all they could do was telling me that the tethering is on and reset my phone a couple of times before making me call customer service, which I could have done anywhere, without the wait.  However, you will need a second phone to call with while your iPhone is undergoing troubleshooting. 
    Hope this helps.

  • Can I get rid of IOS 8.3 and go back to the previous operating system because 8.3 is running my battery down something fierce.

    IOS 8.3 uses too much battery power. Can I remove it and go back to the previous operating system?

    Downgrading is not supported.
    As a test, restore as a new phone, not from a backup, and see if the battery life is better. You can restore from a backup after your test.

  • Should I run down the battery in my iPad before charging it?

    A friend says you should always run the battery all the way down before recharging the iPad or iPhone.  This increases the life of the battery.  Is this true?  I remember years ago that this was true but thought the new batteries don't need that.

    The somebody needs to let Apple know that they are posting bad information.

    For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

  • MBPR: Run on battery or power?

    I have just got my hands on a brand new Mac Book Pro with Retina display.
    My current practise is to run the laptop on the battery, then put it on the charger when it gets either to the end of the day or 10% battery power.
    How should I run the MacBook to get the logest battery life?
    Should I run the battery flat everytime before I recharge? run it on power all the time?
    thanks

    There is a lot of misinformation going around about how to handle Lithium-Ion batteries.  First, and foremost, do not run the batttery down to shutoff every time.  That does nothing good for the battery.  Lithium-Ion batteries do not have a memory like the old NiCads and there is no such thing as calibrating a Lithium battery.  All that can be calibrated is the charge reporting circuitry.
    Next, keeping the MBPr plugged in and running on line power will not harm the battery.  Take it off the line periodically, at least monthly, and run the battery down to 50% and then recharge.
    The charging circuit will not overcharge the battery, it stops charging when the battery reaches 100% and switches to power-only mode.  When the battery charge trickles down to 93-95% the charging circuit kicks in again and tops up the battery.
    Studies by independent testers have found that Lithium-Ion batteries discharged to 50% and then recharged will have four to five times the charge cycle life of a battery discharged to shutdwon every time.  So partial discharging is a much bettery way to operate your MBPr.

  • My MacBook Pro 13" won't turn on 90% of the time I try to get it running, and when it does turn on, even on a charger, it shuts down if I stop using it for 2  seconds and it won't turn back on. Should I replace the battery?

    My MacBook Pro 13" won't turn on 90% of the time I try to get it running, and when it does turn on, even on a charger, it shuts down if I stop using it for 2+ seconds and it won't turn back on. Should I replace the battery?  It doesn't hold a charge either...

    EmadJamal,
    the battery won’t melt because of long connection to the AC charger, although that has the potential of reducing the battery’s life.
    Do you have access to a second 60 W AC charger to test with your MacBook Pro, or access to a second 13-inch MacBook Pro against which your AC charger could be tested?

  • HT4060 Should I let the battery run down before charging my iPad or iPhone to help the battery last longer?

    Should I let the battery run down before charging my iPad or iPhone or iPod Nano to help the battery last longer?  I took a class at Verizon and they said let it drain completely and it would last longer.  Thanks

    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

    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.
