Hi some time ago my phone started having a really strange issue with it's battery the thing is whenever my phone battery gets to around 10% the phone suddenly stops responding and turns off. Then the usual icons telling me to conect the phone appear but after a minute I can turn the phone on again (it still shows the right amount of battery) but again phone is unresponsive, sometimes the top bar (where signal, clock an battery are) disappears and the phone turns of again.

What is really strange I a friend of mine also has the exact same problem, he tried calibrating the battery but it did not solve the issue.

Has anyone expierenced something similar? Is there any potential solution I could try?
Too bad for me I bought the phone on the US and on my country there are no official apple stores only resellers so taking it in for service is not a real option

Thanks

I have the exact same problem. Sometimes my 6s dies at 10%, 20%, I've even seen it go out at 35%. I took it back to the phone company where i bought it and they sent it in for test and inspection. They reset the device to factory settings and ran a stress test on the battery, but concluded that there were no hardware errors and said that it was software related, and that restoring it to factory settings should fix it. It hasn't. I'm still having the same issue, but don't really know what I can do about it. I've had several iPhones before (3gs, 4s, 5s), but never have any of them been as unreliable on the battery as my 6s.

My 6S was doing this as well, and I've had other iPhone's / friend's iPhone's do it as well. The Apple Store generally claims it's software or whatever, and drags their heels, - but each time its been a failing battery which needs replacement.

They sure hate doing that under warranty though!

It's really annoying and I truly believe this isn't hardware because the phone actually turns on again and again if I wait a few minutes so the indicator is correct, I really don't understand what the problem is.

Thanks for the information, I've read about it and I almost never fully discharge the battery usually I charge it when it get's to 20, thing is there are some days I need more juice and it's really annoying I can't use the last minutes of battery
Just throw it in low power mode any time you think you'r not going to be near a charger for a while.

Yeah I try to do that, but I think it's not acceptable to los 10-15% of the battery of a months old phone

Is it possible you have some rogue app draining your battery more than it should?
I really don't think that's the issue because the battery isn't actually draining the phone just becomes unresponsive and turns off, then the connect to charger icon appears, but if I wait a few minutes I can turn it on again. That happens a lot of times until the battery actually drains

Did you try a DFU restore?

I still haven't found a solution for this issue, a full restore did not work

Mine does it too. Sometimes with as much as 30%. The battery also drains very fast and even with very light usage won't last a day. Diagnostics with Apple showed nothing wrong. Bought an Apple Smart Battery Case. Even though the battery is smaller than in the iPhone I can last the day before the case runs out.

Mine is getting worse now it's happening even at 20%, my friend with my same problem took it for service and they told him nothing was wrong so no solution was given.

I reall don't know how to do my phone dies at 20% and that is completely unacceptable

I had a 5S that was doing that, it started about 15 months after purchase (with applecare). After recalibrating several times, and starting a new fresh system didn't fix the issue I ran the online iPhone check from apple's web site. It didn't say anything, except it then let me make an applecare online appointment. They hooked up the iPhone to their computer, and it said the phone/battery was fine.

I mentioned that I had run the online check before I took the phone in, and the apple genius said since the phone failed the online check, they would replace the entire phone.

Of course, at this point I shut my mouth and didn't correct them, and walked out with a refurb iPhone 5s, loaded my backup on the new phone and didn't have the problem anymore.

(I am honestly not sure if the genius had misunderstood what I told him, or he had seen this problem before and it was his solution around the corporate policy of only replacing phones that failed a diagnostic.)

Best of luck, hopefully you can get them to do a battery service, or replace the phone with a refurb.

There's an app in the store called battery life that can show information about the health of your battery. I had the same problem with my old 5s and replaced the battery in it and it quit doing it. I still wonder if it was caused by iOS 9.

my wifes new 6s. about 4 months old started doing this. It would get to 20%, blackscreen shutdown. trying to turn it on immediately is met with connect to charger icon. however after 30seconds it will turn on fine and let you use the remainder of the 20%. I restored from computer and icloud backup. But it still occurs.

I have the same problem. Unreliable piece of sh/t. When I go running (runkeeper and BT) and it is at 30% at the end of the run, than I can just save my run and it shuts down! At 30%! When I boot it up and shutsdown at login. When I connect it to the adapter it starts at 30% and charges. When I let it charge to 35% I could use it to about 10% again, at 10% it ALWAYS shutsdown when I even open YT or FB. For a 850euro phone it's a big shame!!!

What all of you guys are describing is exactly what's happening to me too. It seems to be a pretty common issue, I just hope Apple does something about it.
