iOS 10.1 Battery drain

You miss the point and the example. And you need to undergo a paradigm shift in comprehending that hundreds of millions of users have no issue.

The brake pad example is poorely interlreted. An iOS ipdate is not maintenance but rather the mechanical equivalent of a stress test. And yes, when you do stress tests, as seen on TV shows e.g. Fantom Works guess what? Some new brakesets fail!! As do old ones. Even on brand new brakes!! Hey it even happends in NASCAR and F1.. How difficult is to understand that your iOS update was not there to fix faulty batteries even if not obvious to you days before.

Pure speculation. Have you studied electrical circuits? The only sure thing is that your battery is behaving eratically even after resets. That is a physical process. So unless you are running non stop your flashlight, nope,, your OS is neither draining nor shorting your battery.....

A faulty controlller, be it a mini bios, is still a part of the battery system...

An iOS ipdate is not maintenance but rather the mechanical equivalent of a stress test.

How so?

How exactly is replacing old code on a device stressing it out?

Having performed hundreds of upgrades, fresh installs, re-installs on many hundreds of devices I am not very certain that doing so results in any more stress than just using the system.

Have you any literature which sheds light on your assertion that an update stresses a phone in this case more than say running it day to day or running an intensive game?

I guess I don't yet buy into what you are saying simply because you say it.

Do you have actual metrics that this is the case?

Hello,

I replaced the battery on my 2+ year old iPhone 6 iOS 10.2. The new battery lasted 36 hours and i'm now convinced that my problem was down to two things.

1. my 2+ year old battery was beaten

2. iOS 10 is a battery drainer

So this combination is a killer for old iPhones.

Personally i believe this is a hardware problem and the batteries fail miserably, all is needed a power hungry iOS.

In addition, a brand new battery lasting only 36h is also unacceptable.

Apple needs to fix the power needs of iOS 10, but i don't expect any recall for the batteries of old iPhones.

The question is: a 2y old battery how should it behave? Is that acceptable?

I am sure it's a software issue because on the just-over 1 year old 6s+ I own, these issues appeared overnight after I installed 10.2

No issues whatsoever before the upgrade.

Hi again!

Coming up for 2017, wow, I was born in 1968 and my first computer was a Sinclair ZX81 with 1K of RAM.

How times change.

So, to summarise on this thread:

• IOS 10 has worsened battery life, especially for older phones, I personally believe it has damaged the batteries
• Apple have no idea why and have released diagnostic tools to help them understand why with IOS 10.2, this is good, I hope they find a fix
• Apple are only admitting the 6s has a "Small number of affected batteries"

So where does that leave us?

Well, I tell you where:

When my iPhone 6s (which has already had it's battery replaced free) Bites The Dust, like George Michael, David Bowie, Carrie Fisher and so many others this year.

May they rest in peace.

I am going to move to Nokia, a brand I used and trusted many years ago, looks like they are stepping up their game.

Adrian.

I have had a brake fail, Belisarius. It was after I wore them down.

I never had them fail after getting an "upgrade" to the onboard computer of my car at the dealership...

Per your own logic, if your brakes fail after going to the dealership for an upgrade on the computer, would buy a new car no questions asked??

This apple issue is not from a worn battery.

This issue is with the iOS 10 update which is clearly creating issues with the battery draining faster...not the other way around... my battery is fine....iOS 10 is causing issues with battery. iOS 9 did not cause issues...

Get your head out of Apples derrier and understand that this issue popped up only after iOS 10... not before. There are no "apples" to compare this issue to.....its unique....its a mistake...and it needs to be rectified by apple.....not me spending $$$ to purchase a new phone. My phone is fine. My software that was forced on me is broken...

Apple - this is not a poll....this is a response back to a puppet. Fix this issue, please.

I'be had the same issue with my iPhone 6 since mid October. Must have been just after an update. Very frustrating to have close to 50% power and then phone shuts off. Plug it in and within a minute it's back up to 30% charged. Phone is too old to get free battery replacement, but it's been a long 2 months with no end in sight for a resolution. Unhappy customer...

Same thing here - iPhone 6, bought at the same time as my husband's 6. He hasn't updated to iOS 10 and his battery life is perfectly fine while I at this point pretty much have a land line. The phone dies after maybe an hour of use, and shuts off randomly around the 30-50% mark. It's incredibly frustrating, considering how much I have come to rely on my phone.

Got my battery diagnosed via Apple Support, and they claim it's fine. Tired to DFU it, set up as a new phone, all those things with zero results. Just ordered an external battery pack and plan on using that till we get some kind of answer on what is causing this and what can be done to fix it.

Overall I've been using iPhones since the 3G came out (and iPods before that) and thought I would be an Apple user for life. This current situation is making me want to go elsewhere next time I need to buy a new phone, for the first time in almost a decade. I suspect that depending on how many people are affected by these issues it might cause Apple to lose quite a bit of market share, especially if competitors step up their game and start addressing dissatisfied users.

ONE WORD: FIRMWARE. If you have not worked with it to see how it bricks electronics, I recommend you have a quick 101 read. or at least links below. It is the most dreaded upgrade for any IT specialist. It is only done if a must - Apple with OS rollouts, or special requirements. Each time it is done, IT techs anticipate a certain failure rate. PC vendors generally avoid OTA firmware updates altogether- although modern BIOSs on expensive MOBOS are so advanced that copanies such as Dell roll it out quite comfortably. Car manufacturers avoid letting dealerships do ECU flashes- any sports car living and breathing by it- as once done, the likelyhood of the hardware failing the event is too much of a risk.

So batteries have controllers and a buch of programming, and any new iOS releases software and FIRMWARE on top of the key hardware. Software controlls your OS functionality, firmware, physical hardware.

Of course since not all hardware works perfectly- anyone here believing the contrary should really get a reality check- it also fails. No company in the world makes 100% perfectly working hardware, it does not exist in the engineering world. All these are facts.

Ok Adrian, so you are proving my point that there is a physical battery issue. But the "iOS 10 has worsened battery life argument is not cogent, as nearly 400 million users have no issue whatsoever. You do realize what would happen if only 10% had iPhone issues this holiday, right?

What likely happened is exactly as Apple said for the affected numbers: a tiny fraction had battery issues, and they need replacing. No matter what iOS version you put on, at somepoint the issue will surface.

Therefore the apropriate first trial step, 100% guaranteed money wise, is replacing your battery.

is there a chance that some iPhones may have a short issue? E.G. samsung? Extremely unlikely due to the circuit board assembly process, identic for all and with a variance (industrially speaking) not even 1 in millions, even then, we are talking microns.

In all the Apple Stores I entered (a dozen) have yet to notice a genius watch a phone or laptop shut off, or the battery draining super fast, without them offering a solution- and why Apple scores # 1 customer satisfaction. Same for authorized repair centres. This last bit is a fact. I hope you are not replacing your Apple battery at a non-Apple dealer- that can complicate isues further down the road.

It is true that each time I had a known hardware failure, those basic in store diagnostic tests reveal nothing- but they are quite basic.

If you get a genuine Apple battery, covered by warranty, and your issue is solved, we know the culprit.

More importantly, I stronly recommend you Google whatever "xyz Brand battery issue" e.g Lumina 920 and you will discover the same reality everywhere on Earth, forum wise for each maker- Nokia Microsoft Dell HTC HUWAEi, etc.. The difference is Apple makes the resolution relatively easy, provided one does not expect miracles.Also important, some phones sell 1/100 versus iPhones, but you will se as lengthy forums as well, which means they likely have this issue x100 versus Apple.

At the end of the day, if the issue is confirmed as a battery issue, it proves the point that it is hardware, not software related, and the software merely exposed some issue.

Hello.

Updated my iPhone 5 to iOS10.1 and have been having battery problems.

1 - It jumps from 30% charge to 1% in a few seconds then shuts down.

Now here is the stranger part.

As soon as it reboots after connecting to a charger it show 30% charge. When I unplug it right away it still shows 30% and runs like nothing happened for a good few hours."

Recommend having the battery replaced. Anything else will test your patiente and waist your time. After a few hundred 'perfect' cycles, al Li Ion batteries reach their useful life, and are a single firmware upgrade from revealing the flaw. Anything less than perfect cycles, normal wear and tear, can expose issues sooner or later, randmly. http://batteryuniversity.com/

Most top tech companies take steps to identify and isolate troublesome batteries, more than any component, as it is the single most dangerous item in all our modern devices. So dangerous that aviation safety bans its unregulated shippment.

What this means for you, in simpler terms, is that your battery is failing the iOS 10 upgrade. You shoul dbe able to go back to iOS 9 and older firware, it may resolve the issue, be it that battery is unlikely to be even 90% health.

Of note, I also know iPhone 5 users whom experience no issue.

It's a known fault. See http://uk.businessinsider.com/apple-iphone-ios-10-battery-shut-down-bug-2016-11

The single question I would like answered from this Forum is whether replacing the battery has indeed stopped the problem. I've seen many conflicting posts.

Andy, if you go back in the forum, lengthy read, several users replaced their batteries and said it resolved the issue. I think maybe one may have stated it may not have. The others claiming it resolved have yet to return after a few cycles.

Some disclaimers. As you already know, iPhone 5s and 5S will burn more power under any condition, esp with the newer iOS's. That was documented before, often social media being a huge power consumer, e.g. Facebook. Second disclaimer, not matter the phone, indexing and iCloud and Spotlight will drain the phones fast initially. Completely normal.

IPhone 6 is tricky and will let you google it why. My stating here is likely to get the post deleted. Apple did make statements about reinforcing the unibody for the 6S, and it provided reasons for that. Hence why I skipped iPhone 6 and went for 6S.

Am glad to hear you do understand industrial reliability. The odds for people having defective Apple products are very low, and when they do, it causes often disbelief and shock. Some assume these devices will work flawlessly, and, with 400+ million devices sold in the past 24 months, that is impossible.
