iOS 10.1 Battery drain

Same issue here.

iPhone 6, 64GB.

Started with 10.1.1. 10.2 did not fix.

Apple told me to do a fresh install and not to install my backup. Did that. Still didn't fix it.

I took it to an Apple Tech to get looked at. They reset it again, erased everything and reinstalled firmware and told me not to install any apps. I put a couple apps back on that I needed to have and am still having the same issue. They keep telling me its my apps and told me I have to reinstal the OS for a third time and not put a single thing back on it... I refused. It's obviously not my apps. But because I have an iPhone 6 they are trying to say there is nothing wrong with it. FYI this is not an Apple Store but just an authorised tech as we have no store close by. Battery "passes" all tests.

They are considering replacing my battery or giving me a new phone. But I am curious, has a new battery/phone actually fixed the issue for anyone?

More then anything I just want to add my post to this list so maybe Apple can actually see there is an obvious issue.

Dear all,

+1 here to this list, same issue as described by sotypical.

iPhone 6, 64 GB, started with iOS 10.1.1, still here with 10.2.

This is a really annoying bug that started emerging quite some time ago, I hope Apple will soon release a fix.

Cheers.

Same problem here. Random shutdowns around 30%. Sometimes drops to 1% and shuts off.

Started like a month ago or so. I was running iOS 10.1.1 (updated now to 10.2, problem persist)

I have an iPhone 6S Plus, 64GB and is like a year old.

Live in Belgium.

My iPhone 6S Plus is not covered by the repair program of the "battery bug".... only iPhone 6S could be affected they say... makes me really wonder why I have the same issue then.

My sister has an iPhone 5S and has somehow the same problem.

Workaround/solution so far:

The only workaround I found was to activate "low power mode". This makes me able to last much longer under 30%, sometimes untill it is completely empty. Does this trick always work? Nope... but it does most of the times anyways.

Apple, please fix this soon. Paying over €1000 for a phone and not even being able to use it like it should be, is just frustrating!

Hi Censors, me again.

I know it must seem like we are giving you a hard time and really it is not your fault.

So I apologise to you, but not to Apple.

Tonight I am even angrier if possible than before. My wife has just gone out to her Christmas do with her office and her phone was on 100%.

It has run out. Less than 3 hours.

iPhone 6, 64GB, less than 2 years old and well looked after. It was updated to 10.2 just recently.

I will be visiting my local reseller with it, they will say "Sorry, not covered by warranty or recall."

I am not being cheeky when I say this really looks like Apple wanted people to to buy new handsets for Christmas, overcooked the battery drain and it is now coming back to bite them.

What are Apple going to do about it?

Trust me, I am like a dog with a bone and I will not give up.

Ever.

Adrian.

Iphone 6 128mb I have battery problems since 10.x as described by all. Please apple fix this problem!! Resorted to turning off the battery % on home screen and iignoring it. The phone seems to last the same actual time as before, it's the percentage that's just all over the place.

Hi, been a long time Apple user here (since the 3GS) and I have to say that this problem is very disappointing. Disappointing that it went undetected to start, that it's gone on for so long, and the lack of communication.

I wanted to throw my 2 cents in that I've had the same issue since 10.1.1, even with battery saving options enabled: the vast majority of background refreshes off, reduce motion on, etc. I had no issues with iOS 9 with the same settings.

Changing battery Will not resolve it as this is clearly a software issue. We a lot of feedback here that changing the battery won't resolve.

Sadly Apple seems to be more revenue focused and choose resolve issues for customers which they still have contractual obligations to (under warranty phones). Nothing wrong with that. Just that they risk losing customer loyalty and that can take even more resources to earn back. Look at how vw ignored issues and is suffering the consequences now. Too bad for us.

Do update us. I upgraded to 10.2 and it became worse. From 20-30% shutdown to 40-50%. After 4-5 times of shutdowns at 40-50% I rolled back to 10.1. Doesn't solve the issue but the shutdown is back at 20-30%.

I had the following experience with Apple support.

I contacted them via twitter, not really to get a solution but trying to make them more aware of the problem.

The technician ran some remote tests on my phone, said that it was ok.

Asked me to reset the phone and then restore a backup, this is interesting because in the Genius bar they had told me to not restore the back (which I did). I explained to the technician that I had done that already to no avail.

So he had a senior support person contacting me on the phone. He asked me some questions but when I mentioned that I thought the problem was with iOS he just changed the topic. He didn't say no, it's not iOS or we don't know, he simply ignore it which somehow tells me Apple has told them not to say anything.

He recommended me to go to the Genius bar again and check the phone again, and maybe replace the battery, but he made it clear I would have to pay for it since I am not under warranty, I told him that I wouldn't have a problem paying to have my battery replaced IF it would solve the problem, but two different tests showed the battery doesn't need replacement and I know some people did it but the problem didn't go away.

I am certain it's iOS and I strongly suspect it has something to do with the GPS. If I am running a battery draining app that doesn't use GPS (e.g. videos) it doesn't drop, but if I am running a gps enabled app, it does when it reaches certain thresholds, and now it's getting worse, dropping from 50% to 1%, then back to 50 as soon as I plug it in, I have to have a battery charger with me all the time and this is getting really frustrating.

No. Apple has stopped signing iOS 9.3.5. This means that iTunes will deem 9.3.5 as an invalid firmware.I tried. Earliest version we can rollback is 10.1 which is what I did. Doesn't resolve it but but it's back to 30% shut down. With 10.2 my ip6 it worsened. 40-50% batt shutdown.

Great post,

I've recently discovered that Apple are replacing batteries for free on certain 6s models, looks like they are finally admitting they have a problem...

I'd check this out first and see if you can get a bettery replacement for free rather than having to pay.

Good luck.

Turns out I am eligible for a free battery replacement

At least Apple is admitting that have an issue now...

Restoring without backup does not help. I have done it for my iPhone 6 64. Same issues. But your are right. The drain happens in extreme when surfing on internet with 4G, LTE AND even more so 3G.

I now bought another phone for my day to day as I cannot work with this bug in iOS. The phone is kept for testing out newer releases of iOS till they resolve it.

It's well discussed here that replacing batteries doesn't help. It's issues with iOS not the battery.

Adding to the list here - I know this is an iOS issue for sure (not hardware) and Apple rarely admits to these things. Only way to fight back is to post and not buy Apple anymore. I've tried every supposed trick in the book but a total restore because I've not read or heard that it has worked once. I also always do full iOS update via iTunes.

iPhone 6 64GB and didn't have the battery drain issue until iOS 10.1.1. The battery drops quickly sometimes 10+% in an instant. I then saw there was a second 10.1.1 via iTunes about a week after first coming out. Apple said you didn't need it and it wasnt offered over the air (I believe Apple's way of hiding the issue). Well the 2nd build of 10.1.1 fixed the battery issue. I updated to iOS 10.2 and now the battery drain issue is back and maybe even worse.

So much for Apple quality control and all about the dollar - though long term this will only hurt them as over time loyal customers will move on. Here's hoping they do their customers right and iOS 10.2.1 solves this issue for good.
