    As the title suggests.

    Had it just over a week. It will visibly hold on at 16% for example and then step down to 14% and miss out 15% altogether.
    On other occasions it has dropped from 31% to 29% in one go. Very annoying. My iphone 5 did this but with bigger chunks (18% to 14% for example).

    I've only charged it three times but never from totally flat.

    Any ideas?

    Gotta be the iOS 8 bug, mine does that too. Hopefully 8.1 will come out tomorrow and fix majority of the issues.

    Might be worth calibrating the battery - run down battery completely until the phone turns off, and then recharge fully to 100%.

    Well that is interesting but i'm getting mixed responses because some say that the battery drain is fixed and some say they aren't. What my concern is whether the stacks+backboardd issue is fixed on 8.1. I keep getting this log on the diagnostic and usage page.

    Anyways I noticed mine draining horribly couple days so I decided to do a DFU factory restore to 8.0 and did a fresh install and set up as new and unplugged my phone at 5:30 am this morning and it's still 100% (with 30 minute usage). Prior to this, my battery went from 100% to 99% in just 20 minute, which isn't right because most of the time it's always after 30 minute of use that I lose 1%. But doesn't really matter.

    But I did notice a huge drain because before going to bed it was at 75% and woke up to 70% 7 hours later. So something was clearly running in the background. I normally just lose 0% to 1% overnight.

    Ok this is really annoying me.

    60% and 54% battery simply do not exist on my iPhone 6. It always jumps from 61 and 55 respectively. I let the phone completely discharge and I then recharged to 100%. The thing is, once I unplugged, I noticed it draining to 89% within an hour with just 25mins of use. I switched it off and back on, the battery was at 95% !!!

    I'm so frustrated. I'm m on my third iphone 6 now, the other 2 did not do this.

    Update.

    15% battery does NOT exist on my iPhone. It has on every occasion dropped from 16 to 14 and it did so just now. I then immediately plugged it in and it jumped back to 16. I unplugged it and it dropped to 14.

    What does this mean? Have I got a broken battery? This is my third iphone 6 and this issue is happening at other times too (60% also doesn't exist for example).

    I am so, so annoyed. Can anyone share their thoughts on this please?

    Nothing works.
    I have tried everything you can mention. I have let the battery die 3 times now, recharged for 6 hours uninterrupted to past 100%, and performed hard resets. 60% battery does NOT exist on my iPhone 6. Neither does 50%, or 15%, or 10%. it just jumps and misses those out.

    Do I have a broken phone?
    Is there any way I can run the diagnostics that Apple used to check?

    If you chat with Apple online they can actually run a remote diagnostic check on your phone.

    The last thing I could think of is this...This is what was causing my battery to drain 25-30% overnight,

    Constant LTE to 4G switching:

    You guys seriously think this is a problem because it doesn't display every single percent digit that goes down?
    That indicator is there just to give you a general idea and not up to the second accurate. Off course it will drop 2-5 percentages or more at a time here and there.
    Find something better to do and stop worrying over nothing.
    Better yet turn the percentage indicator off and stop calling AppleCare over nonsense. Get a hobby instead of sitting there waiting to see if the battery thing skips a digit.

    What? Who the hell do you think you are? I've had every single iPhone, and this is the first time it's happening, so I think it's legitimate to wonder why it's happening.
    And by the way, I don't even need to wait for it to drop. I wake up my screen, 45%, after 30 secs of usage, it's drops to 43 or 42%.

    I'm just a normal person that doesn't stress or get crazy about such nonsense.
    All my iPhone's always dropped battery percentage numbers randomly. If I do heavy battery intensive use as video games, Gps navigation it goes fast and never falls one by one.
    And guess what? I'm not having a heart attack over it cause I can charge it again when the battery gets low.
    Seek professional attention :D

    Another update....

    Something odd is happening.
    60% still does not exist on my phone. It dropped from 61 to 59 so I immediately plugged it in and it went back to 61. When I unplugged, it dropped to 59. However, 50% also never used to exist but on this charge cycle my battery fell from 51 to 50 as you'd expect. But, 30% also does not exist. Drops from 31 to 29, skips 30 when I plug back in etc.

    I also noticed when I charged it up, it went through 10% normally whereas before it would drop from 11 to 9.

    Could it be the battery needs a few more charging cycles to fully wake up?

    I must admit, I haven't yet upgraded to 8.1. Maybe that will help.
