    Having the exact same issue here. The phone will easily charge to 100% in an hour or so, but if it's plugged in over night it's 96%. The iPad2 manages to charge to 100% overnight with the same IOS version. If we're all having this problem, Apple definitely needs to fix it.

    same problem here. white iphone 4s 32gb.

    You all have a new phone in which neither the battery nor the reporting software has had enough time to settle down and calibrate. There is nothing to fix.  Is the speedometer of you car accurate to a single percentage point? Have you complained to the manufacturer?

    I tested it some more. The next two days were fine. Fully charged and remained that way until I unplugged it. Today, however, it hit 100%, then stopped charging. The battery symbol was still there, and the small icon had a plug in it, which should mean its fully charged. It then started dropping, like it was no longer plugged in. But the fully charged icon remained.

    I'm not sure if this is a flaw or feature. It may be healthier for the battery to not constantly fluctuate between 99% and 100%, hence why it stopped charging. But I would like to have it at least remain above 95%.

    It's also an issue that in standby, the phone drops 5% or more every hour. The iPhone 4 used to only drop 5% all night.

    Hmm, today I left my iPhone 4 charging overnight and saw 100% in the morning. Pretty good. So I can agree, maybe this is kind of calibration or something else.

    I have this same issue with my 32 gig 4s. I know it will charge to 100% in a couple hours or less, I'm thinking that once it hits 100% it simply stops charging and switches to battery power for the remainder of the night. When I wake it is at 93% ish. So I undock it and dock it again and before you know it 100%.  I think it is a either a safety thing to avoid battery damage by excessive charging or it is a software flaw whereby the device ends the charge cycle when full but fails to draw from power from the dock for the remainder of the time it is plugged it.

    For me, it's pretty clear what's been happening so far. As other have said, once you get to 100% charge, it appears as if the phone starts discharging, even when it stays plugged in. Then, at some point, it starts charging again, goes up to 100%, and the cycle repeats.


    So, if you've seen this problem, and subsequently see your phone at 100%, it's worth leaving it alone for awhile to see if it starts discharging.


    Is this a calibration thing? Too soon to say. I'm letting my phone run down to see if that helps.


    Is it a problem? Well, I've never seen another Apple battery operated device behave like this. It seems unusual.


    (And to the gentleman who asked if I'd take my car to the shop if the speedometer was off a couple of percent? If I put my car into cruise control and then watched it waver by 5-6 MPH, from time to time, sure I'd take it in, especially if it was still under warranty. It really not supposed to do that. But I also wouldn't run around with my hair on fire exclaiming the end of the world. It's a minor, albeit annoying glitch, that will either clear itself up with calibration or with, I'd guess IOS 5.01.)

    I reset my White 32GB iPhone 4S and it jumped from 18% to 99% charge.  I had it plugged in for a couple of hours and saw it was still @ 18%, so decided to reset to troubleshoot if it was a phone or charger issue and got the results I suspected.

  • taylorlynn89 Level 1 (0 points)

    I don't know if this is purely cooincidence, but I restored my phone on Wed and after charging overnight the battery was at 100% when I woke up... I also noticed that my batter has lasted much longer (especially in standby). It was at 50% by the time I went to bed last night @ 10pm so I figure I will let the battery drain again.

  • UltrabeaT22 Level 1 (0 points)

    Same Problem here in the UK like everyone says it will chardge mega fast to 100 but if i do it over night the charge will drop to 93%


    ive had it a week and have done 4 cycles charges. at first i thought it was one of the battery pro apps i was using now this morning arfter not using one i know it isnt.


    im gonna have a word with apple cause its not right... ive never had any product where my batery takes a week+ to work properly.


    i find the only solution like most of you is to unplug it when i wake up and pop it back in again to let it top up to 100


    calibration issue? I think not.

  • UltrabeaT22 Level 1 (0 points)

    Just a quick update for those who do look at this.



    i did a restore under apples recommendation and last night was my first 100% charge.....

  • Bill37 Level 1 (0 points)

    My new iPhone 4S also doesn't reach a full charge. When I leave it in the charger overnight, it's at 96% some 10 hours later. (Unplugging and then replugging the phone will bring it up to 100%.)  My iPad, also running, iOS 5, works fine.


    Is there a solution to this problem?

  • tonefox Level 6 (9,155 points)

    Yes. Stop freting about it and let the phone bed itself into its new world. The software takes time to calibrate itself to the battery.

  • Bill37 Level 1 (0 points)

    I hope that's true, but given 1) the large number of people who are having the no-full-charge problem and 2) that this hasn't happened with previous iPhones or iPads, software calibration doesn't seem to be the issue. Do you have any technical documents or Apple references that confirm it's a software calibration problem, or that shed some light on this?


    As far as I can determine, it's not possible to tell if this particular problem is hardware or software related. It would be great if the no-full-charge problem was software related and an iOS update fixed it. But for now the problem persists.


    A fully charged phone is something that's both expected and actually useful.


    <<Stop freting about it and let the phone bed itself into its new world. The software takes time to calibrate itself to the battery.>>

  • tonefox Level 6 (9,155 points)

    My opinion is, as ever, unclouded by knowledge. But how does your "large number of people" who are having the no-full-charge problem compare with the four million sold in the first weekend, and goodness knows how many since?


    As regards the usability of a phone charged up to 96% compared to one charged up to 100%, I know that I would not be able to spot the difference.


    Wait. There are other solutions given in the various threads regarding charging which you might like to try, such as a restore, but i would wait, as no discernible difference in actual usage is likely, beyond the number at the top right corner of the screen.


    Battery problems take over these forums as soon as every OS update arrives, only to fade away.....
