My 6 just shut down with 54% showing plugged it back in and it went to 53%. At least it waited till 30% previously. It's becoming unusable. Pretty crap for an 18 month old phone

My 6S went away for repair before Christmas, and since it came back it's randomly shut down again 3 times.

I'm running out of excuses for Apple now, and i've always been a bit of a fanboy.

Apple have just run a diagnostic check on my phone. (God knows what info they downloaded). They now seem to have disappeared when it comes to giving me the results

Got the result. A phone shutting down with 53% showing is 'normal'. That was a useful experience rolleyes

I wonder what the actual cause of this is? I can't remember having anything similar on other devices. Battery degradation happens on all devices, but the OS usually calculates it correctly.

And is it battery degradation? Is it fixed by installing a new battery?

Just had one on my daughters' iPhone 6S replaced because of this battery problem, and it didn't show on the link posted above. My other daughter's iPhone 6S, purchased at the same time, is now doing the same and will be off for replacement next week.

It's weird, I'm not convinced the battery is degraded necessarily, I just think the phone doesn't know so just turns itself off. Sometimes I can get it started again with some battery life left. Other times dead as a dodo. I like apple stuff but having to keep your phone plugged in is just annoying.

I explained to the apple guru on the live help part of their website that I had done a backup and refresh and am running latest iOS. He did a diagnostics check which showed the battery as ok. All he could come up with was a reset pressing home and power button together. I've done that countless times but he stressed to do it when plugged in on charge and battery indicator shot up. That was around lunchtime and I'm down to 66% now. I'm waiting to see when it decides to shut down this time.

It happens because the software which is supposed to measure how full\empty the battery is has got it's knickers in a twist so it's reporting the battery as having 40% charge when it doesn't or vice versa. This usually happens because most people don't charge their phones fully according to the instructions in the manual when they first get them as they are too impatient and can't wait those few hours to switch it on and have a play, I did exactly the same thing myself.

If your phone is not on the list to be replaced you can still fix this by just conditioning your battery properly which also resets the battery percentage app to show properly.

Are the instructions for that somewhere in this thread?

There are 2 issues ongoing. The first is a real battery issue which is resolved by replacing the battery (or phone). This issue had a limited impact based on number of handsets.

The second issue, that Apple are very aware of, is that one of the IOS updates "broke" the battery management and they have not been able to fix it. They can't admit to it because the negative publicity would destroy their stock. And, everyone would be demanding a replacement which will have the same issue. There have been several minor updates to the current rev IOS but none have been able to repair what they broke.


The hope is that with the next update this will quietly go away.

It won't even make a dent.
Just saying.

Haven't been able to solve this issue. I've just bought an Anker charging case and it's transformed the phone. Easily get a day out of it now. The £35 has saved me having to fork out for a new phone.

Since downloading and installing IOS10.2.1 the other day on to my 6, the battery meter and random shutdowns has dramatically improved. Last shutdown was at 6% which I can live with. After installation I restarted the phone. Anyone else noticed improvements?

Same here. Although it's been bad today with it shutting down at 27% and then once plugged in showing 1% then jumping to 33% within seconds.

If you're bothered, phone Apple, they can run diagnostics on your phone and tell you how many charges you've been through. They warranty up to 500 charges, ,mines done 1300ish so the fact it's still lasting is quite good according to them. I still think batteries should last much longer and be guaranteed for more than 500 charges though.

Got gifted a 6s from my brother when he got the 7 on release and its safe to say he hammerd the phones battery, he is the type to always be on his phone so its had a hard year.
The battery life was terrible, an hour browsing the web would take it from say 90% to 20-30% easily. Apple replaced the battery for free seeing as it qualified and now its superb.
