Q: iPhone 6S shutting off at 30% battery

iPhone 6S, iOS 9.3.4/5 (problem on both).

 

A couple weeks ago my phone started shutting itself off at around 30-40% battery life. Then the charge screen shows if I immediately try to turn it on again. If I wait 15 minutes and turn it on it says it still has ~30% battery remaining and it will normally stay on all the way down to 1-2% battery.

I ran it all the way down, let it sit for a couple hours, then charged it all the way to 100% while the phone was off. The problem still persists.

I also did a clean restore (set up as new phone).

    This is happening to me too. Common circumstance seems to be camera use. Phone shuts off at 18%, 25%, 33% 50%, or any other percentage. Will not come back unless plugged in. Phone returns with roughly the same percentage battery as when it shut off.

     

    Very frustrating---but now I'm almost certain this has something to do with the camera. My wife is also experiencing the issue. I have 6s and she has 5s. Issue persists in both iOS 9 and iOS10. I use "Camera+" app and she uses standard "Camera" app.

     

    Apple refuses to acknowledge an issue with the iOS losing it's connection with the battery as a result of using the camera, but this issue is becoming more and more clear to me.

    The reason the problem shows with the camera is simply that the camera uses more energy than any other app. The base problem is most likely a battery that is failing. Take it to an Apple store where they can test the battery. Or get the app Battery Life, which seems to be reasonably accurate in measuring battery condition.

    Thanks, Lawrence. I did exactly that (battery test at the Apple Store last week and also over the phone with a senior advisor, plus clean restore, etc.). Battery looks good. Now Apple is acknowledging a problem with the iOS (both 9 and 10) connecting with the battery under certain conditions. A senior advisor was instructed by the engineering team to collect my phone logs (crash logs, etc.) so they can work on this serious issue. They have already collected logs from many others as well, and many others are complaining about this same exact issue.

     

    My case number is 10002703746. Senior Advisor Derek Johnson strongly encouraged me to edit or reply to my above post and ask people with the same issue to call Apple, speak with a senior advisor, and provide crash logs for the engineering team.

     

    I will be asking for a new phone this week to see if even slightly degraded batteries are too far gone to use the camera. If this is the case (my phone is heavily used but less than a year old), Apple will be inundated with this issue soon.
