Ten days away: what about the battery?

Hi,
I'm going to leave for ten (10) days, not bringing my iBook with me. It will stay OFF for all that time. What about the battery? Is it going to get stale? How much shoud I charge it before I leave?
Right now I'm really proud of it: full charge = 6:30 hours!!!!
Thanks,
Stefano.

Stefano -
I'd say ten days would be OK without having to do anything special, here are a few links that talk about battery storage and other battery related information.

  • What about the battery?

    Good afternoon
    Well I got my Macbook Pro 15 "2.2 GHz with 4 days of use. When pulled out of the box had 6 hours of battery still left to finish the battery without the Power. ever since then I have more than 3 hours maximum battery life. What will happen? Sorry for my poor English

    3 hours is normal battery life. But battery life is also dependant on use.
    check out this link for tips from Apple:

  • HT1657 Can I watch my rented movie for just 24 hours? What about the 30 days? The countdown on my library returned in days countdown rather than hours. Can anyone clarify me about this?

    Read the article you linked
    iTunes Store: Movie rental frequently asked questions (FAQ)
    How long do I have to watch a rented movie?
    You have 30 days from the time of rental to watch your movie, and 24 hours (in the US) or 48 hours (elsewhere) after you've started viewing to finish it. Once the rental period expires, the movie will disappear from your iTunes library."

  • Hello! I'd like to know about the battery. Can it lose the capacity? What can i do to prolong it life time? Full charge? How to proceed ? Thanks.

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

    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.)
    http://www.apple.com/batteries/notebooks.html
    "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.
    From Apple on batteries:
    http://support.apple.com/kb/HT1446
    http://www.apple.com/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

  • Mifi 4510L Mifi Hotspot...is it the network? and what about the firmware update?

    I have spent several months trying to seek a solution on the repeated and frequent disconnects from the Verizon wireless network using my Mifi 4510 L.  No success.  I have conversed with Verizon Wireless "experts" on this matter and have basically been ignored, since they do not have a solution. It has cost me a pretty penny in wireless costs due to lost connections in downloads, etc...for which I do not get any credit from Verizon on my wireless bill...go figure.
    I have even been accused by Verizon that the problem is my computer and hardware, even though I have ran several hardware, software, and "real-life" connection checks on other wireless networks with no issues at all.  I even have been getting better connectivity when I use my Verizon USB UML290...but I hate having to switch moving my SIM card from the USB Modem to the MIfi4510L...one of these days the SIM card will fail. Verizon has checked the signal strength at my home and work locations (which I already knew as good), but never heard back from them.
    Anyway,  I have verified that my wireless network adapter works just fine on other wireless networks (no dropouts, etc).  I have even upgraded to another Windows Operating System - Windows 7...which is more superior than Vista in dealing with wireless communications.  I have implemented quite a number of the solutions provided by other great Verizon Wireless Community members, but the connectivity problems continue to occur.
    When I did a review of my wireless hardware logs, I noticed that when I was encountering problems, the dynamically assigned address given to me on the Verizon Wireless network changed quite a bit, even when I was using the same web site. When my wireless connection worked fine, the dynamically assigned address was consistent.  This seemed to change when I encounter peak network load times. 
    I would appreciate a straight answer from Verizon Wireless on what is going on with the network.  I live in a solid 3G coverage area...but just far away from 4G to benefit for the increased throughput.  The closest 4G location footprint is about 40 miles away from me.
    Finally, what about the Mifi 4510 L firmware update?  I have yet to see any notification about this firmware update, either through normal e-mail channels or even through my Mifi configuration site
    http://192.168.1.1/mifi.cgi
    What gives?
    I realize that I am sounding a little perturbed about this matter, but it has been almost 4 months now...and Verizon is not living up to their part of the bargain on providing good tech support on the Mifi 4510L.  When they do not have an answer...they ignore the customer.   Not good business!!!

    The firmware update was released a few weeks ago and there were multiple threads in this forum for it:
    Software Update: Verizon Wireless 4G LTE Mobile Hotspot MiFi™ 4510L
    The firmware update primarily addresses a problem with the MiFi switching from 3G to 4G and back.  I would not expect it to resolve a connection issue for anyone in a 3G only area.  Work through the firmware update instructions included in the link above and see if it helps. 
    There were no email notifications but the MiFi should have been redirecting you to the MiFi homepage every time you tried to browse the internet.  The firmware update is mandatory so if you have not already completed the update then there might be something wrong with your device. 

  • I spoke with Apple about the battery and they said...

    it might be a software issue to where something is not installed properly in the backend in which im hoping. I talked to them for a good 20mins in regards to what alot of us are experiencing about the battery life not being what its supposed to. he said they've gotten a good amount of calls this week about the iPhone not holding its battery charge throughout the day. I asked what can i do on my end to try to fix this problem. he said to backup and restore your iPhone like you just bought it to reinstall the software.
    plug in to iTunes -- backup iPhone -- restore -- when "set up or backup" screen comes on, unplug. keep notice of the battery to see how its going. if its still dropping noticably then its a battery problem, if not then it should be working as normal. i might have to drive 2hrs to get a new iPhone if this doesnt help but hopefully this will help some?

    Some clearly have faulty batteries.
    hopefully Apple puts out a new update quick.

  • What is the battery average of the iPhone 4S running with the 5.1 IOS ?

    So... what is the battery average of the iPhone 4S running with the 5.1 IOS ?

    I don't spend time worrying about my "average" battery life. To figure that out, I'd need to keep track of exactly how long it took my battery to run down. I'd need to run the battery down every time. I'd need to do this for weeks to get any valid data. I have a life. I charge my phone at night and take it off in the morning. If I need or get the chance to charge it some other time, I do.

  • Paranoid about the battery

    Ok, I got my nano today and I have fallen in LOVE with it. Just wondered about the battery though. I got it out of the box, choved it on my Mac and away i went! It said it was fully charged after like an hour though - not even that? I took it out anyway, was I right to do that? Anyway, I was just thinking about this '12 hour battery life' thing, when are you likely to get this 12 hours? At a medium volume setting with minimum backlight etc?
    I just think the battery will go down a lot quicker (all of my friends iPods have *not so good* batteries so didn't want this to be a continuing problem)
    Thanks anyway
    ijmac

    I'm scared now though, this morning it said battery was empty and I needed to recharge, when recharging it didn't take 3 hours (I don't think) to recharge fully, it took less (maybe 2?)
    Also, when just unplugging the charged iPod the battery icon went down a bit? When i first got my nano, i charged it for like an hour (until it said fully charged), then as the icon went to half way, shoved it i again, soon after than i unplugged it to let it go all the way down to charge fully (as people recommend)
    Please don't say I've buggered up this wicked iPod =(

  • Just got my iPad 2 three days ago and noticed the battery life drops faster than I expected at least compared to the others ones around

    Just got my iPad 2 three days ago and noticed the battery life drops faster than I expected at least compared to the others ones around, please I need to know the cause and how to effect necessary changes that will prolong the battery life as I have gone through the settings which includes turning off the push notifications, reduce brightness and so on but that doesn't seem to help much.

    FYI
    The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) 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 (2.5W, 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
    http://www.macblend.com/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.

  • Which Bag do you use for your Camera? What about the GadgetBag 300EG?

    Which Bag do you use for your Camera? What about the GadgetBag 300EG?

    I agree - it's all about preference.  I use the ThinkTank Retrospective 7.  I *love* ThinkTank's attention to detail...  everything from having a rain cover included with the bag, to having ingenius use of velcro (sp?) patches to enable you to "silence" the bag so it doesn't make the big "SCRATCH" sound when opening the bag during a quiet event, etc.
    My best advice would be to do your research (which you're clearly doing) and have a clear understanding of the return policy wherever you buy it, and then don't be afraid to return it if you get it and feel it doesn't meet your needs.  A restocking fee is a small price to pay to not be stuck with a bag that doesn't work for you.  And if for any reason you get it and can't return it, there's always eBay.

    i want to produce wedding dvds.whats the best software to use...final cut x I'm thinking but what about the quality of the dvd? Can i use idvd?

    The only Programms I worked with are DVD Studio Pro and iDVD. You can burn a Video-DVD with Toast but  there is no real option to design your Menu. Just a few themes as far as I discovered.
    Do you have a Blue Ray Device to burn* the HD-DVD? Are the Bride and Groom able to watch the Blue Ray?
    * which is only possible with DVD Studio Pro and not iMovie as far as I know.
    This might help
    For better quality I would go the Compressor & DVD Studio Pro workflow I just learned.
    Export the Movie as is from Final Cut Pro and then use Compressor to encode the File.
    Consider delivering the Movie in a different way like a private video on vimeo, a Website or on an SD card which is not really romantic...

  • Some questions about the battery

    I have a couple of questions about the battery in general.
    Is it normal that my iPod Touch 4G charges very fast? It reaches 60% in only one hour and it's fully charged before it takes two hours. I know this is not bad but I'm just worried. How can I be sure if it's really loaded?
    Is it normal that the battery is very quick empty when I'm gaming? For now I'm blaming this due to the quick charge.
    Is it normal that for example my battery level is at 30% and when I put on standby or something or close a game, the battery starts rising for approx. 5% even 10% sometimes?
    Those are my question, I hope they are clear enough. Thanks in advance.
    Regards

    1. The tech specs says:
    Charging times: Fast charge in about 2 hours (80% capacity), full charge in about 4 hours
    2. Heavy use like gaming drains the batery fater then other use. The tech specs say:
    Video playback time: Up to 7 hours when fully charged
    3.. Yes, the indicate capacity tends to rise after heary draining is stopped.  The battery indicator is not that accurate is affected by temperature. Heavy use increases battery temperature and when it decreases battery temperature decreases.
