iPhone 6 keeps turning off

[Anonymous]

My iPhone 6 keeps turning off when the battery is still at 20/30%. 

I have tried resetting the device, but still no luck.

Is this something I can take to O2 to fix or apple? 

I am in a pay monthly contract.

Hi @Anonymous I wouldn't even think of sending it to O2. Go to Apple ...or give them a call

Apple are replacing batteries in some phones due to a fault.
You can check if your serial number is effected here https://9to5mac.com/2016/11/28/apple-how-to-check-iphone-6s-battery-replacement-serial-number/
However, there has been a large number of complaints regardless since ios10 was launched so there is some suspicion that it may be a software issue.

Try a full restore via iTunes. If that doesn't work then book a Genius Bar appointment at your nearest Apple Store to get it looked at.

That's a serious problem and should be rectified by Apple not o2 unless you want to wait longer and pay. I assume you have warranty so waste no time in getting this sorted.

Could be in warranty but equally it could have run out.
It may just be a faulty battery and nothing more serious at all.

And a faulty "built-in" battery isn't serious?

Batteries are easily changed but I'm not sure about a bettery?

They can change a battery for you under the program for you but they may charge a fee if it is not warranted as part of the program units affected

What's a bettery when it's at home? A new kind of phone?
