Will it hurt the battery to give only partial charges?

Sometimes when I am getting ready to leave the house I have a 50% charge, but only 20 minutes to charge.  Will it hurt the battery to give only partial charges, and on a fairly regular basis?

No, that will not harm the battery.  Just discharge and charge whenever convenient to keep the charge level high enough to power your needs.

    If I use my ipad2 while plugging in the wall charger (charging), will it hurt the battery?

    No, I do it all of the time. But based on what you are doing, your activities may use more energy than the 10v charging and you still use the battery, just at a slower rate.

  • After installing Mountain Lion the battery indicator shows only 99% charge though charging for the whole night.

    Hi,
    I have been using MacBook Pro mid 2010 and recently I upgraded my OS from Snow Leopard to Mountain Lion. Since then whenever I charge my computer it stops charging at 99% but when I was using Snow Leopard it use to fully charge to 100%. Does installing the new OS preventing it to charge to 100% or something is wrong with the hardware.
    Thank you
    Regards

    Thanks for the reference. Still one thing I am not able to understand is that in Snow Leopard after the full charge it use to show 100% so why not in Mountain Lion. Snow Leopard is also a advance OS and if that is the case then the feature of not charging to the full capacity should exist.

  • Is it okay to use the iPad while it is charging? Will it affect the battery?

    My iPad battery sometimes runs low and I plug it in and continue to use it while charging. Is this safe for the battery to do so?

    Yes it is safe to do so. I am using my iPad while it is charging right now. When the charge is complete, it will quit charging on its own. You will not hurt the battery.

  • Help I have a Macbook 2006 model and I like to play videogames on it, well when I leave it plugged in it gets the best performance, when its not plugged in its decent, so will it hurt my battery if I leave it plugged in at all times?

    No, it will hurt your battery, but it is not recommended by Apple. Additionally, since you have a model with a removable battery, you should calibrate the battery once a month if you leave it plugged in at all times.

  • Will leaving the charger in hurt the battery on the New MBP 17"

    I rarely need to unplug my new MBP 17", but with all the talk about battery problems, I wonder if I should unplug it from time to time and not just leave it plugged in.
    Right now its been plugged in for a 1.5 weeks... While I don't think this could hurt the battery, I thought I would ask...

    http://www.apple.com/batteries/notebooks.html
    "For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. *Apple does not recommend leaving your portable plugged in all the time.* An ideal use would be a commuter who uses her MacBook Pro on the train, then plugs it in at the office to charge. This keeps the battery juices flowing. If on the other hand, you use a desktop computer at work, and save a notebook for infrequent travel, Apple recommends charging and discharging its battery at least once per month."
    http://batteryuniversity.com/parttwo-34.htm
    " A lithium-ion battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often or use a larger battery. There is no concern of memory when applying unscheduled charges."
    "Although lithium-ion is memory-free in terms of performance deterioration, batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem. Letting the battery run down to the cut-off point in the equipment will do this. If ignored, the fuel gauge will become increasingly less accurate."

    This last link is the best summary of good advice on maintaining lithium-bsed batteries that I have ever seen.

  • Hello.  I recently pieced together a late 2008 MacBook Pro 15".  Everything works fine except the battery constantly goes between "not charging" and "calculating" or, rarely "charging". It does charge after a long while and will report that it is charged.

    I have reset the NVRAM and the SMC a couple of time but that didn't work so I ran an Apple Hardware Test and while testing the logic board it gives the following error:
    4SNS/1/40000000 LB1T
    I've done some research and found this is a temperature sensor related to the battery, but cannot find where the sensor is located in the computer.  Would you know how I can find the sensor to test it?  Could my battery problem be related to something else?  Would a fresh install of Lion help?
    Thank you!
    Mike
    Two pieces of information that may or may not b helpful, the hard drive is from my early 2008 MBP and the only test disc I have access to is from an iMac.

    Why do you have LION installed on that older machine?
    So you say you built a macbook from a bucket of parts eh?   Kudos

    I  am using 2 unit provided AC charger to charge my iPad mini. After a while, I checked the device. The battery is no longer in charge mode. It is only 80% charged. When I touch the AC charger, it is hot. I need to switch off the AC charger to let it cool down before continue to charge my iPad mini again. Of course it will be 100% charge but must make sure the AC charger is cool down completely. 
    I feel that the provided AC charger that is not suitable for our charging on iPad mini.

    I would book an appointment at an Apple Store, if you have one nearby, to have it looked at.

  • If i keep my computer plugged in all day will that ruin the battery???

    Absolutely yes, it will ruin it.
    *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.)

    "Apple does not recommend leaving your portable plugged in all the time."
    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%.
    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.
    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.

    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

  • When I try to charge the battery, my i-pad says: "charging off", how can I change this, so my i-pad will just start to charge as before, without any complications?

    Perform a Reset... Try again...
    Reset  ( No Data will be Lost )
    Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
    Wait for the Apple logo to Appear...
    Usually takes about 15 - 20 Seconds... ( But can take Longer...)
    Release the Buttons...

  • If you use your iPod Touch while its charging, will it ruin the battery life/battery?

    I have an iPod Touch 5th gen. and people say that if you use your iPod/iPhone while its charging, the battery life will deacrease or the battery will be ruined/shot

    However, you should almost fully discharge and fully charge the battery monthly otherwise you will degrade the battery.

  • Mountain Lion 10.8.1 update the battery life get only 5:6 hrs after a full charge.

    The battery life got only 5:6 hrs after installing the first update 10.8.1. Strangly the remaining time keep on changing up and down. It show remaining 2 hr, then for sometime show 3:00 hr!!! Don't know why. It looked like the battery life calculator mulfunction.

    The remaining time reported is not an actual remaining time of use. It said 6 hr but in a normal use is much less than that. Say around 3:30 hr of real and normal use of my Macbook Pro.

  • If you charge your iPod when its half way or like 85% will it degrade the battery?

    I use my iPod for like 10 minutes then I charge it. Will this effect the battery in any way?

    However, to maximize battery life Apple recommends almost fully discharging and then fully charging monthly.

    If I have my iphone 6 on oovoo or any other app on the whole night while the charger is plug in, will that ruin the battery?

    No. The phones are smart enough to stop charging once they are full. Most people plug in their phones overnight, and just unplug it in the morning and you are good to go. I hope this helps!
