Has the battery percentage indicator been acting up lately on your iPhone 6s or iPhone 6s Plus? If so, you’re not alone: this is a known issue, according to Apple’s newly published support document.

“If you change the time on your iPhone 6s or iPhone 6s Plus manually or change time zones when traveling, you might notice that the battery percentage doesn’t update,” reads the document.

Apple is aware of the problem and working hard to deliver a permanent fix.

To help alleviate the issue, Apple is proposing that the affected users to do this:

Step 1: Restart your iPhone.

Step 2: Go to Settings → General → Date & Time and make sure that Set Automatically is turned on.

If this happens again and you didn’t change the time or time zone on your device, you should contact Apple Support.

    My iPhone 6 is doing this. After updating to 9.1, the battery only lasts like half the day. Fully charged in the morning and then during the afternoon sometime, it’s already down to like 20 something percent. I was about to update it to 9.2 to see if it did a fix for it. But guess not, thank goodness I read this first.

      I think you mis read the post, the battery indicator doesnt update. Has nothing to do with actaully battery use. But simply lack of battery information.

    • pegger1

      I don’t think you read the story here at all.

      • Agreed

    Also have an issue when starting the camera,, IT freezes and takes 3-5 secs to get ready for shoot … Wtf ???

    • Your battery is knackered. I had this with my old i5s and replacing the battery solved it.

      your battery is broken… too much heat? too much cold? or simply a factory problem…

    I’m getting this issue on my iPhone 6S Plus 128GB running iOS 9.2 (iTunes update, no restore from backups). Reported this to Apple about 2-3weeks ago. My old iPhone 6 was running 9.2 then 9.2.1 and now 9.3b1 and didn’t have this issue at all. This happens especially whilst charging. I’d also appreciate it if Apple fixed the random lockups when unlocking/waking the device with TouchID, the lockscreen will stay for about a second and the phone unresponsive before taking me to the homescreen. Really ticked off by this. Unacceptable for the top-of-the-line flagship device.

      I’m not experiencing the time/battery issue but the TouchID one i do have as well..

      Hoping it get fixed on iOS 9.3!

      • Mr_Coldharbour

        You’re probably the only other person whom I’ve asked directly and have the TouchID wake/unlock random lockups/freezing in the lockscreen. Glad I’m not the only one. The battery % not updating happens to my 6S Plus when I’m charging it, not while it’s unplugged though. Sometimes it’ll be charging and stuck at 45% or so for a while then slowly go up to 46-47% and so on.

    The same with iphone 6 :S

    How can a clock configuration mess the battery percentage?
    Sometimes I just cannot believe on bugs iOS has.

    • mrgerbik

      Maybe the meter updates with a timed poll. When you mess with the time, the poll function(?) isn’t properly updated.
      Only the programmers would understand

      • ClaudieX X

        The meter calculates how much battery do you have, looking the drain of the programs using time and mah factors… so is not so crazy for me…

    Off topic, but what is the average usage time from a 6s plus that people should get? I feel that my battery is preforming poorly. I have to recharge my phone everyday. My phones shows 5-6 hours of usage and 7-8 hours of standby at the end of the day with under 10% juice left. I don’t use it for any demanding task, I only generally surf the web during the day (no games, phone calls etc)

    • Every day is pretty standard. I have the 6s+, I wake up at 6am and go to bed about 11pm, I work during the day and have to charge it by around 2pm so that it lasts until I go to bed again.

    • Mr_Coldharbour

      Sounds rather poor. I get on average 8-9hrs usage and over 40hrs standby (on a single charge). I can stretch it to 10-11hrs if I keep screen brightness to a minimum and limit my use of Instagram and cellular data.

      You might want to check in Settings > Battery > Battery Usage per app to see what’s draining your battery. You might want to turn OFF Background App Refresh under Settings > General. Also try a complete restore of your device (start as a NEW DEVICE and not restore from Backup). If that doesn’t help, take your device to an Apple Store and get an exchange or something. Charging a 6S Plus everyday and only 5-6hrs use is quite poor, my old iPhone 6 lasts longer.

      • Tim smith

        Ah thanks, sounds like my suspicion that I may have under average performance is confirmed..ill try restoring and setting up as new. Safari is the all draining battery the most but I don’t know why. I have turned off the iCloud setting for safari so that shouldn’t be causing any issues.

      • Mr_Coldharbour

        No problem, I’ve turned off everything iCloud, don’t use it really. I thought I had subpar battery performance on my 6S Plus but you’ve got it much worse. But hopefully a restore should fix it. Also, try not to drain the battery too much, not more than once a month or two months.

      • Tim smith

        Yikes! I probably drain my battery at least twice a week. Hopefully this restore I do when I have some time will help. Thanks for your suggestions and input.

      • Mr_Coldharbour

        Oh you shouldn’t do that. It’s highly advisable that you don’t do that more than once a month, even that’s plenty. Try to keep it between 20-85% as much as possible, charging it to 100% is fine also, but don’t drain it to 0 a whole lot. Further doing that will degrade the life/health of the battery.

    • h4nd0fg0d

      My 6s+ battery has been phenomenally good. I game more than anything and it performs beautifully. Always keep my brightness to a min, 25-30%.

  • ClaudieX X

    I live with low battery mode all the time with my 6 and it last 24 hs… sometimes a whole another morning too (if i’m not playing too much 3D games) I traveled 2 times with it and changed the time but this problem never happened…
