Hi Guys,

Any advise of how I can go about Apple fixing the battery?

I have an 18 month old iPhone 6 Plus and for the past few months the battery has barely been lasting a whole day and the battery percentage jumps around a lot i.e. it will drop to 20% and then a few minutes later will drop to 10% and then to 0%. when I plug it in it starts up at 20%. Other occasions when at 20% if I plug it in it jumps up to 30% immediately.

I had apple look at it and they said the battery health was 89% and thus acceptable and did not need changing.

To me this sounds exactly like the battery issue that happened with the iPhone 5 a couple of years back.

How do I go about getting Apple to acknowledge the problem and then fixing it?

Thanks
 
Did you buy Apple Care +? If you did, take it back to the Apple Store and see another genius. If you don't have Apple Care +, they'll change the battery but it'll cost you $79.00.

Haven't got apple care. It should still be covered under UK consumer law as its only 18 months old. Also previously they had a replacement program for iPhone 5's having the same issue.
 
I'm not familiar with UK consumer law, however, taking it back to the store and seeing another genius is what I would do. You may have to elevate it up to the manager level if necessary. As far as the previous replacement program for the iPhone 5 battery, I don't believe that applies to the 6 series.
 
So I spoke to Apple again. Apparently its a known software glitch and doing an update in recovery mode might fix the problem.

Will update this thread with the outcome.

Update: Restoring the software did not fix the problem of the battery percentage bouncing around and the phone switching it self off randomly.
 
If Apple did a battery diagnostic and found that the battery has an 89% full charge capacity - then that is what is causing your issue. Apple considers anything over 80% to be passing, but you will definitely see some jumping around of the battery percentage and even the phone powering off at <20% when your battery has been depleted past a 90% full charge capacity.

Batterys naturally become consumed over time. If you are under warranty, Apple will cover the replacement battery (if your battery has an 80% full charge capacity or less) as a courtesy. Doesn't seem like your phone qualifies because it is out of warranty and the battery hasn't dropped below a 80% full charge capacity.

You may be able to get Apple to make an exception to change your battery early, but it will cost $79.

This isn't like the iPhone 5 where some units had defective batteries that would actually fail instead of being naturally consumed; or the battery would even swell up.

Thanks for the info. Not sure i can survive till October with such poor battery life. Will see if apple are feeling kind otherwise will have to pay to get it replaced.
 
It sounds like it could be a calibration issue. I know in the past, I've had similar problems (less so with the 6, however) and that sometimes just running the battery all the way down to empty before charging it all the way can help to re-calibrate it and give you a more accurate reading. It sounds like the battery itself may not be defective, rather your readings are simply out of whack.

I felt like my 6 was having battery drain issues last summer after only having had it less than a year because the display kept feeling hot to the touch and like it was "overworking" itself. I brought it to the Apple store and they didn't seem to think there was an issue with it but fortunately replaced it anyway. If you don't have any luck re-calibrating the phone with the above method I'd just take it to the store despite the warranty being expired and see if you can get one of their reps to see the issue for themselves and hope that they acknowledge it and help you out by replacing the battery (or better yet, the phone). Apple is super conscious about their customer service experience and uses it as a major selling point for their brand so if you can kind of push that point a little you might have some luck. Fingers crossed!

I thought the British consumer laws should protect you well in such a case - against the seller of the goods that is.
Best of luck anyway!
