Q: IOS 9.2.1 iPhone 6 Erratic Battery

For the last 2 months I have noticed that the battery on my iPhone 6 is very erratic. This morning I woke up to it showing 2% (57% when I went to bed), I plugged it in and it immediately showed 48%. I have restored phone completely and this issue is still occurring.

    Howdy MissCaro,

     

     

    I understand that your iPhone's battery indicator appears to not be updating correctly. Fortunately the article linked below details what to do in this situation, and should help return functionality to your iPhone's battery indicator.

    If your iPhone 6s or iPhone 6s Plus battery percentage doesn‘t update

    Regards!

    HI Allen,

    thank you for your time, but Date & Time was already set to automatic, and I have never changed my time zone. So although I was hopeful, this was not the solution as my phone just jumped from 6% to 37% when plugged in.

    Using the battery level meter in this manner is comparable to using your car's fuel gauge to calculate miles per gallon. The only thing that matters is the total amount of operating time from full charge to auto-shutdown.

     

    Use the wall-mount charger that came with the iPhone and charge overnight.  Do NOT use a computer's USB port.  Then, operate it normally until auto shut-down (ignore any low level alerts that may appear).  An irony is that doing that test to determine the total operating time is also the procedure necessary to calibrate the battery level meter.

     

    I'm not claiming that you do not have a problem.  I am stating, however, that we don't yet know.  If the above test does, in fact, indicate a problem, read this.

     

    Also, according to Apple:

    Use Your Device Regularly

    For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

    Elsewhere, Apple elaborates and explains that two half-discharges (or four quarter-discharges, etc.) equals one full discharge.

    Hi Philly_Phan,

    Thanks for the comparisons and resources, I did calibrate the battery, and have yet to see any positive changes. I was also contacted by Apple to get support. I followed all their steps, and again kept having trouble they are "aware" of these glitches from the latest update yet would like me to pay to have a new battery put in on my dime. I guess sticking it out and carrying a back up battery is the best solution until they either fix their glitches (which to me seemed to have caused the problem in the first place) or I spend more money to fix it.

    This article describes a potential solution to your problem, especially since it seems you have tried everything else.

    Hmmm...

     

    I don't know what I would do under the same circumstances.  I'd probably go for a battery IF I could get some agreement that my money would be refunded if it made no difference.  Of course, my chances of getting such an agreement are slim to none.
