Not understanding charge cycle

This is my first time I have ever owned an apple product. For the iphone 5, is it better to recharge the battery before it reaches 20% or after. Also would leaving the phone connected to the charger for 13 hours after being fully charge damage the battery?

So leaving the phone connected to the charger after being 100% charged for 10 plus hours won't do any damage to the battery?
No.
And, no to your edited post.

  • HT4623 Has anyone had a problem with Iphone 4s battery not holding charged status

    My 4S Iphone would not sync although it would charge when i connected it to my computer. I  got help from an apple representative who walked me through syncing with icloud to get back my contacts.  My phone wil not hold a charge since then. Apple diagnostic said the battery was perfect??

    Hi pamellag,
    Here is some information on iPhone batteries that may help you:
    Apple - Batteries - iPhone
    http://www.apple.com/batteries/iphone.html
    One of the side notes states:
    Charge Cycles
    A properly maintained iPhone battery is designed to retain up to 80% of its original capacity at 400 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.
    The 'replace' link above leads to some options if you need to get the battery replaced:

  • My Macbook Air 11 (late 2010) not charging "battery replace now) message 28 months old only 6 charge cycles. what could cause this?

    I've unplugged plugged in. Checked the charger. Nothing runing. I've Shut down rebooted ran diagnostics and just about everything resolution I could find on-line. Its almost always plugged in and has not been used on battery power in a long time. Its not run down to zero power before. Just suddenly shut off the other day and won't charge now. Says replace battery now, but I just want to see if it could be something else. Hard to believe the battery went bad like that.
    Thanks

    always plugged in and usually in sleep mode.
    So it was always plugged in, never discharged, and was never really OFF, just in sleep mode.
    Sounds like you got some half-true 'advice' from some people. 
    It DOES shut down when fully charged and you cant "overcharge" your macbook....., and the "others" were correct that your battery should be cycled every couple weeks at least.
    what they didnt tell you is "plugged in and OFF is one thing.......plugged in ALL THE TIME...AND in sleep mode (for years)......NO!" 
    Heres some info for the "next battery" :
    Keep it plugged in when near a socket so you keep the charging cycles DOWN on your LiPo (lithium polymer) cells / battery.
    *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
    If you leave your macbook plugged in all the time, take it off charge and drain the battery down to 15 or 20% every couple of weeks or so.
    LiPo (lithium polymer, same as in your macbook) batteries do not need conditioning. However...
    LiPo batteries do NOT like to be dropped down to 15% or so often,....key word being "often"
    A lot of battery experts call the use of LiPo cells the "80% Rule" ....meaning use 80% of the charge or so,.. then recharge them for longer overall life.
    Never let your Macbook die from power, you can corrupt files that way, and the batteries do not like it.
    **Also new evidence suggests that sudden loss of power can adversely affect data on a SSD (solid state drive).....again, dont let it ever shut down from total power loss
    The only quantified abuse seen to LiPo cells is instances when  often the cells are repeatedly drained very low.
    Contrary to what some might say, LIPo 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 dont take a new car out and speed and rev the engine hard first 100 or so miles.
    *Also, if youre going to store your macbook away for a few weeks or more,... make sure it has at least a 50% or so charge.
    *Cycle count / use/ lifespan is one thing that cant be countered.
    Proper treatment is another thing. Just because LiPo batteries dont need conditioning in general,.. does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesnt need conditioning.
    Just use and enjoy your new macbook, 
    From Apple on batteries:
    http://www.apple.com/batteries/notebooks.html
    http://support.apple.com/kb/HT1446
    but really all you would keep in mind is --"consider 15-20% is the same as 0% and recharge it"
    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)"

  • Why is my charge cycle not zero?

    I just purchased my macbook pro 13inch (mid 2014) from a IT fair, 2 days ago and charged it ONCE to 100%. However, today when i checked my charge cycle, it reflects 3. Is this normal? I tried to google if anyone has similar issue but can't seem to find anyone who does so. Does this mean that my macbook might not be a brand new one?

    Yes. That is normal.Testing the battery at  factory can add 1 or 2 battery cycles.
    Best.

  • 1-year old MacBook Pro suddenly not holding charge

    My MacBook Pro
    (750GB Hard Drive, 8 GB RAM, i5, 2012 model, OS X Mavericks 10.9.4)
    is just barely over a year old; I got it in July of last year (and therefore just over my 1-year warranty) suddenly has terrible battery life. I do not know what's up:
    Early last week I had it in school and I started the day at 83% battery, and I used it all day long, I got the usual 7 hours, everything was good. I didn't do anything very intensive over the weekend, some word processing, played with Xcode (Beta of Xcode 6) for school, everything's fine. Yesterday I checked the battery (it seemed oddly low) and I had a service battery notice.
    I did some research, and checked a few things: my model is rated for 1000 charge cycled before loss of optimum performance, and my cycle count in System Report is 496. I rebooted my MacBook and the "service battery" notice disappears. If I Option-click on battery it states the condition is normal. But I am getting terrible battery life; 3 and a half hours from a full charge.
    Last night I did a battery recalibration: charged to full, left it plugged in at full for two hours, discharged 'til it turned off, and left it off all night, then charged it to full today. Now, it alternates between saying I have 3 & half hours to four. Right now it says 4 hours at 80%, which is an improvement, but still very low.
    The only two options I can see I have left are taking it into an Apple Store, which would not be ideal, the Province I live in has one Apple Store, and it's a two-hour drive from where I live (and I don't have a car, and no means of acquiring one, woe!) or doing a reset of the System Management Controller as detailed here:
    Intel-based Macs: Resetting the System Management Controller (SMC)
    But that seems a tad on the extreme side, and I don't fully understand the repercussions of that action.
    What would you, O Apple Community suggest I do? I could really use some guidance here.
    Thanks,

  • My battery is at 516 charge cycles, charge capacity of 4129. Is it defective?

    My Macbook is a late 2009 white 13" unibody model, and I understand that it should withstand up to 1000 charge cycles.  I am only at 516 charge cycles, yet my battery life is dwindling, lasting approximately half as long as it did when new.  I've seen it drop from lasting for five or six hours with normal use to two or three hours with normal use just in the past few months.  System profiler says its full capacity is 4129 mAh; this is after I reset the SMC and calibrated the battery in an attempt to fix my problem.  It charges to the indicated capacity but as I said, lasts nowhere near as long as one would expect.  I remember its capacity being around 5100 when I first purchased my Macbook in April of 2010.
    Obviously the laptop is out of warranty - not like it matters, since batteries aren't covered.  What I was wondering is if this battery would be considered defective considering it has only lasted half as long as it "should" according to Apple's standards.

    My charge cycles reflect daily use, and I can't imagine how it is excessive.  I guess it might be, but I use it as I think a laptop is intended to be used.  I don't leave it plugged in all day; I make use of its portablility and run it on battery at least half of the time.  I usually plug it in before the battery reaches 20% as recommended by Apple, but it has on a few occasions been completely drained.  I don't think my use is extraordinary.
    Since posting this my laptop has fully recharged after the calibration, and its status has changed.  It used to say that my battery condition was "service needed" (which is what prompted me to look at how it's been performing) but now the stats read as follows.  Even the capacity changed, which is interesting.  I guess recalibrating the battery removed the service warning, so I'll see how long it lasts off the battery alone over the next few days.

  • My daughters ipod 4th gen will no longer charge past 20% and will not connect to a pc in order to back everything up. the cable is working fine, otherwise it would not even charge to the 20%. i have tried the reset to not lose any data and no luck. help!

    my daughters ipod 4th gen will no longer charge past 20% and will not connect to a pc in order to back everything up. the cable is working fine, otherwise it would not even charge to the 20%. i have tried the reset to not lose any data and no luck, home+power for 10-15 seconds. I really would like to not lose everything she has, again, because I can't back it up this time. I have tried charging via a wall outlet and PC and both charge fine, just only to 20%. I am using the cable that came with it so no aftermarket issues there. Please help so I don't have to reset everything again.

    Because once it has charged enough to be powered on as soon as you turn it on it says battery is at 20% and will not charge anymore after that, it just runs for about 5-10 minutes before the battery dies again. The battery cycles discharge/recharge daily and its not on the charger at full charge for more than a couple hours and is never totally dead for more than a couple of hours.

  • To CHARGE or NOT to CHARGE, that is the 3G question!

    Man I am so confused.
    I read CHARGE it like a laptop thus if near a plug, plug it in as its like a laptop and goes on cycles not turning 20% and then charge into your 20% becoming the 100% then having 1 hour on your battery.
    So, which is it?
    I have read WAIT until it gets to 10 or 20 percent then charge, I have read *drain it all* the way BEFORE charging, I have read *plug it in like laptop* which seems to co coincide with *APPLES PLUG IT IN if near power supply.*
    SO WHICH is the best way and second, it does seem to me to that the GPS and BATTERY life are shorter after the update and apple needs to let us revert back WHILE changing the base band as well.
    Also, Apple must have known about the battery issues and therefore did not solder the battery on this time and SCREWS are near the bottom. That mentioned, how much can be done with updates as we have millions of users now and his is not 10,000 people with BAD batteries on their macbooks or ibooks but millions and I foresee a mass exodus of returns in two weeks.
    So what happens then? If you're with AT&T and have been and haven't upgraded in years and bring it back and say, I still want to stay with AT&T but am going to use my old phone and look at others, I would think that they have to make you eligible again for another phone.
    I was jacked about the phone and thought 10 hours of NET USE iPOD was great but then the stupid update or rather ME being stupid, updated it and it seems to have lost some time, so maybe this can be fixed, either way, I don't want to be a guinnia pig so might have to return it just in case.
    Wish someone from Apple would just say what is going on an offer 2 batteries or something. Heck I would take a iPhone that allowed us to swap the battery for another or some sort of SUPER CHARGER that S-U=P-E-R charges in 10 minutes. or a solar panel charge clip for outside use/charge.
    My time is almost up too - need some answers.

    I read CHARGE it like a laptop thus if near a plug, plug it in as its like a laptop and goes on cycles not turning 20% and then charge into your 20% becoming the 100% then having 1 hour on your battery.
    So, which is it?

    This applies to old batteries based on NiCd or Pb. They had a "memory" effect.
    However, since years new devices (and also the iPhone) uses Li-Ion batteries, which do not have this effect. There isn't any need to discharge them before charging any more. It does not matter when and how long you charge, it won't affect battery life. As the battery power decreases with the number of charging cycles (one cycle = 100% recharge), you should connect them to a power supply whenever possible.
    To the cycle topic an example: charge it from 90% to 100% day one, from 80% to 100% day two and from 30% to 100% on day three, makes 10%20%70%=100%, which is one cycle. So here you would have one cycle in three days.
    Apples states that after ~1000 cycles you will have 80% of the original capacity remaining.

  • What is the max charge cycle?

    What is the max charge cycle?
    If it reach the max, will apple replace it under warrenty? or it not covered, and I have to buy new battery?
    Like when you go to System Pref > About this mac > Power > Recharge Cycle.
    It will tell you the amount of charged you made. What is the max you can recharge?

    A properly maintained Apple notebook battery is designed to retain up to 80% of its original capacity after 300 full charge and discharge cycles. See http://www.apple.com/batteries for lots of good info on Apple batteries.

  • Will not start charging

    my computer will not charge. it says that the power is connected. but do not let what can I do about this?
    when I do a battery test, it tells me that the battery is okay.

    Hi, I have the same problem with my HP Pavillion dv6-2136el.
    The original battery stopped working after 18 months.
    I bought a new battery and after 2 complete charge cycle, the battery stopped working again.
    Then I bought a second Battery and the malfunction is always present.

  • Can someone explain this chart about Li-ion charge cycles to me

    I consider myself a pretty smart guy, but i couldn't figure this out. I'm thinking that apple just provided this graph without any real explanation of what it means. I'm talking about the one on .. http://www.apple.com/batteries/ that has a caption starting with "Charge Cycle." They provide a general explanation of cycles below, but don't seem to address the same thing the illustration they provided does. What does the 40% 20% 30% 20% 50% 60% mean? Why is "1 Cycle" in the middle and what is the difference between cycle 0-1 and 1-2. basically that illustration makes no sense to me and i'd love for someone to explain it

    That charge is telling you how the charger charges the battery. The voltage charge is the green line and the amperage is the orange line. Voltage goes up to its full extent in the first couple of hours. The amperage starts at full charge strength and goes down as the batery charges so it will not overheat the battery. The most important thing to know about charging a Li (Lithium-ion) battery is that it has two different charge times, quick and full. most Li batteries get about an 80% charge at the quick charge time and 100% charge at the full charge time. when you first charge any rechargable battery make sure you do a full charge and then a full discharge with another full charge afterward. If you do not do this the life of the batery will be significantly diminished.
    I hope this information helps. If you want more information in this subject ask a more direct question.

  • What exactly is a charge cycle?

    Hi, everyone! So I recently just bought a MacBook Pro with Retina display (about 4 days ago) and I'm really trying to take of it, and it's battery especially. I've tried looking up some information on the best ways to take care of it, and I always come across people taking about things like "charging cycles" and "calibrating the battery" and I have absolutely no idea what those mean!
    I don't mean to sound like an idiot, but keep in mind that I am completely new to the world of MacBooks. I've tried to research what these terms mean, but I've found nothing.
    Please help and give me advice on how to properly take care of my precious MacBook Pro. I adore it so much and I want it to last as long as possible.
    Thank you so much!

    despite anything Apple.com has listed, the lithium-polymer battery is a KNOWN entity and its technical behaviour is a known entity, regardless of inside an Apple product or not...
    having it plugged in everytime you use it is one thing, ....but some leave it plugged in 24/7 ALL THE TIME,...not a good idea,.....no hard, it just doesnt do the battery any good, and does minor wear on its lifespan.
    Exactly lIke permanent magnets..., lithium polymer batteries dont like HEAT ,......perpetual trickle charging (leaving it plugged in alllll time time) is the unwise choice.      "

  • Adapter/charge cycle question

    Sorry for all the questions. This will be my last one.
    I use my iPod with a FM transmitter a lot at home and in the car while having it connected to the adapter. Does using the adapter still count as a charge cycle?. Say, hypothetically, I use the iPod + adapter for 15 hours straight, is that still one cycle even if the adapter is keeping the battery fully charged.

    As far as I have read, 'top-off' charges are not detrimental to the iPod and may extend the life more than depleting the battery. Always 'exercise' the iPod from time to time.

  • I have an 11 week old Macbook Pro that has 15 charge cycles and the design capacity is at 91%, is that normal or should I take my laptop into the store?

    Hi, everyone I'm just wondering whether my battery life is normal. I've only had this macbook pro for a few weeks. According to coconut battery, as well as the information under about this macbook. The macbook is 11 weeks old and after 15 charge cycles it is at 91% design capacity? Is this normal or do I have a faulty macbook?

    The batteries are supposed to hold 80% at 1,000 charges now - not sure when this started but was a couple of years ago maybe.
    Personally I would not worry too much. If you actually notice a signigicantly bad drop in battery life after some time, instead of just by looking at numbers on charts, then yes take it to Apple, but for now, just enjoy your computer.
    After more charge cycles, it may become more accurate too - when I first got my MacBook Air it was on about 94% after only 15 charges or so, now it's on about 620 and is on 84% or so which is on par with the 1000 charges -> 80%.
