battery percentage jumps to 100 percent during charging and falls to 'real' percentage when disconnected

Hello

I charge my new iphone 6s and I noticed that evertime I plugged my iphone on my macbook pro, as the battery percentage jumps to 100 percent. Then, when I unplug it, it jumps down to the 'real' percentage. IM currently draining the battery to make a new calibration to see if that fixes the problem. Any ideas on why this might be happening would be greatly appreciated.

Thank you.

Drain the battery could do more harm to the battery. Have you ever tried to force reboot the phone by holding down the button sleep and home for 10 seconds, until the Apple logo comes back again? You won't lose data by doing this, but it can cure a few glitches.

Implementation in the new device would be the next step after that, where force restart does not work.

  • iPhone battery percentage 6 stuck

    Hello, I have an iphone 6 purchased from Apple about the release two years ago, never had any problems until this Friday, 10 March 16 when I noticed my battery percentage was is no longer draining after moderate use. He would stay at 100 percent every day and then turns off randomly. I have iOS 10.0.2, have tried to reset, power on/off, restore factory... nothing works! Is someone able to please shed some light on why this might be the case? Google tells me that there was a similar problem earlier this year when those who have no zone defined as auto has encountered a similar problem with the battery percentage being stuck and not up-to-date (i.e. no reflective battery drains with use). I went to settings and noticed that my time zone was not set as automatic. Does anyone else have this same problem and what is the reference for this?

    I'm surprised that factory reset did not fix this problem... help...

    Hello.

    First, plug in your iPhone, let the screen off and do nothing for a long period of time. Leave it plugged in all night while you sleep is perfect for that.

    Then, restart your iPhone by pressing and maintaining the sleep/wake and home buttons.

    You can also try following the suggestions of battery life. Go to settings > farm > find 'Suggestions of battery life.

  • HP Photosmart Plus 209 has: com.hp.devicemodel.transportproxy uses 100 percent of the CPU, persistent problem

    Hello

    This process HP com.hp.devicemodel.transportproxy seems to have a life that he has - he's eating 100% CPU, even when finished printing and the printer is not connected.

    The old NET on this http://h30434.www3.hp.com/t5/Inkjet-Printing/com-hp-devicemodel-transportproxy-uses-100-percent-of-t...   suggested delete and update the drivers of HP who I did it - but it did not help and the problem is still there up until I go to System Preferences > printers and to remove the printer (I can't just delet the process in activity monitor, while it keeps!).   Not really elegant.  And if you forget to do it continues to run, 100% of the CPU and becomes very hot, even when the lid is closed.  Not nice.

    No fix for this, HP?

  • generation iPod Nano 7 jumping battery percentage

    Hello.

    I recently got an opportunity 7th generation iPod Nano and the battery percentage jumps around. I use it and it seems that it is half-percent or less then I turn off the screen and turn the screen turn it on again to change the song and it will pop up to like more than half. Is this normal or a kind of glitch that I should take to the Genius Bar? Does that mean I have a bad battery? Thank you.

    Try to let the game iPod continuously, until it is unloaded.  You can let them play unsupervised until he stops playing alone.  Then, connect it to the power for a few hours, so that it is completely recharged.  See if that makes the battery to act more reliably.  It is good sometimes to drain the battery completely and then load it completely.

    Hi there alara11,

    It seems that your phone battery does not charge, and your alarms do not seem to jump when you value. We should be able to solve that with troubleshooting software, so I would like to start by leaving the clock app and the settings:

  • iPhone battery percentage 6 unreliable

    Hi all! I use an iPhone 6 with the updated iOS (10.0.1 for now). Since iOS 9.3.4, I noticed a lack of reliability of the battery of my iPhone.

    During normal use, the percentage jumps down about 10-15%. If at this time that I plug the battery pops up by about the same percentage. In other cases, the iPhone still for a long period of time even with the battery that may not be true, or it shuts down even if it is not 1%.

    I went to the Genius Bar and the genie made a diagnosis called 'mobile Inspector' who has not revealed something strange. The employee told me to calibrate my battery, follow these steps:

    (1) restore settings (no);

    (2) use the iPhone until it stops;

    (3) leave here 2 hours without connection;

    4) recharge 100% free to use it and leave it there for 2 hours more.

    (5) repeat step 2-4 once.

    I did what she suggests, adding a force restart after point 4.

    The problem is still there. Day before yesterday, the percentage rose from 85% to 90% (without connection) and yesterday he jumped from 40% to 30% and then stayed at 3% for 1 hour.

    I booked a call of support for tonight see what I can do. The iPhone is still covered by the warranty of 2 years Italian.

    I encountered this problem a few months ago. I went to a Genius bar and my iPhone has been replaced. I don't know if genius made the same tool of diagnosis or a closer, but he acknowledged that the problem was due to hardware, perhaps due to the battery connector. They do not have to replace the battery, but gave me a refurbished iPhone.

    Someone at - he seen this problem and found a solution?

    Thank you

  • Z510 - fake battery percentage

    I bought Lenovo Ideapd Z510 about 1.5 years. Installed 10 Windows via Windows update 3 months ago. My laptop was working fine until now. 1 week ago I just changed a document and suddenly portable got off without any notification. He did not stop rather he turns off unexpectedly. Shown before setting power off battery percentage was 70%. I tried to turn it on but also used the recovery key, but nothing helped. I plugged in the charger and the charge indicator noticed was RED, which means the battery is low. I turned on the laptop and now the battery percentage shown was 0. Self decided to execute gauge reset it using Lenovo Energy Manager, which in turn will calibrate the battery.

    After two days I though that he's fine now. But I have PES on my laptop for 2 hours and the specified battery life was still 94%. I got that wrong info is displayed. I generated enery powercfg-energy command prompt report. Once I opened the report that I was surprised to see tha last full Charge value is greater than the design capacity, which is quite bizarre. Now, it takes two or three hours to charge completely from 99% to 100%. And even after lsitening to music, surf the Web and edit several documents at the same time battery percentage shown never becomes less than 94% and thatbtoo it takes 2 hours to go from 100% to 96 or 94%.

    Please help me. I want to know what it related equipment and in particular the battery or with the operating system? Note that I did not install any new application or a program in the past 5 months. Thanks in advance.

    Hello

    I have the same problem. I keep that suffer over the months, but with the new update is even worse.

    This happens especially after I turn off my phone for the night. When I turn on the battery down over 20% or more.

    today when I switched on the battery he was 43% and then it off later. I could not turn it back to the. I tried after a few minutes, then he works with 43% unexpected. then he fell 23%, and since he has never changed.

    When I put the phone in charge the battery seems to be gaining a return of 20% extra.

    is also a 5s.

    any chance someone has a solution to this issue? I was reading the forums and there seem to be many posts osimilar, but apple seem not to care about it.

  • In "Services.exe" CPU usage increases to 100 percent XP.

    In "Services.exe" CPU usage increases to 100 percent XP. Attempt to disable Load System Services through the system without result Configuration utility, because cpu cannot handle this function before of 'Services' system of pigs. Is there a way to access msconfig. through BACK? Have tried all modes safe mode, same problem.

    I would exercise caution in handling things in the System Configuration utility.  If you disable the thing (s) evil, you could make your problem worse.

    I suggest provide you a little more information on your system, run some scans for malware, then fix what's left more that needs fixing.

    If you see services.exe equips in the Task Manager, suspect malware first, work to eliminate this possibility (with the scans below), then if you still have a problem, we can fix.

    It makes no sense to try to solve problems on a system that could have malicious software on it.

    You can also try to run system restore if you want, but I don't really know, it counts as 'fixing' of the problem.

    Maybe someday the dialog box 'ask a question' forums XP will ask these questions automatically when a new thread is started so I don't have to ask every time.  It might even be possible to solve a problem in a single response when enough information is provided.

    Please provide additional information on your system:

    What is your system brand and model?

    What is your Version of XP and the Service Pack?

    Describe your current antivirus and software anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc..

    The question was preceded by a loss of power, aborted reboot or abnormal termination?  (this includes the plug pulling, buttons power, remove the battery, etc.)

    If the system works, what do you think might have changed since the last time it did not work properly?

    No matter what you use for malware protection, perform the following analyses for malware.
    then fix any problems:

    Download, install, update and do a full scan with these malware free
    detection programs:

    Malwarebytes (MMFA): http://malwarebytes.org/
    SUPERAntiSpyware: (SAS): http://www.superantispyware.com/

    They can be uninstalled later if you wish.

    The scans by operating clean, then to solve any problems.

  • Sansa Fuze battery: percentage indicated

    Hi all - I've noticed recently that the percentage of battery remaining indicated on my Sansa rockets - I have a 2 and a 8 GB - differs the battery percentage remaining indicated through my computer when the device is plugged into the USB port on my PC.

    E. g.: verification of my view of "System Settings > Info" on the "rocket", I see 27% duration of remaining battery life.  I immediately connect the "rocket" in a USB port (my computer has two; either one).  The 'Properties' indicator for the rocket of remaining battery life is 63%.

    It's constant and reproducible.  There is always a HUGE disparity between the percentage that appears on the "rocket" itself and the percentage indicated via USB/PC connection.  Note that the rockets still indicate a much lower figure.

    No idea why this is happening?  Thank you very much in advance for any answer!

    I run them down.  As I said, I charge them when I see they are about 20%.  As JK98, mentioned in the "Fuze Battery Life and good practical battery" thread here: "the battery prefers a partial rather than complete discharge. Frequent full discharges should be avoided when possible. »

    If you are let off at 20%, which is almost fully discharged. Circuit of the rocket will turn off right around that level to prevent permanent damage to the battery or the charging circuit. Let down this low once in a while is OK, but I wouldn't make a habit of it. Better to load when it comes down to 50% or more. These types of batteries prefer to be crowned often, rather than the older style batteries that worked when deep-cycled.
