iOS 10.1 Battery drain

That battery life gauge inconsistency is the key I believe. I think the function is broken and is tricking the OS into thinking the battery is dead. When the OS thinks the battery is dead? It turns off. I think there are multiple problems here. Apps that don't run efficiently with this update. And a broken power monitoring system.

"Yet before the update I did not have to remove the Facebook app. Or turn off Music options. That tells me this new update is buggy and not running efficiently with at least these two apps. As an update. My phone ran normally down to 20~%. Put it back into the Mophie and charged it back up to almost 100% now. I did notice there are still problems although not as severe with the Facebook app removed. Remember. I had ZERO problems before the update. You can blame my battery. I'm not convinced."

Would you agree that, as an example, an user with 300 cycles on iOS 9, and uses the same apps, is operating his hardware in a certain electrical balance? Nothing new, lost or gained, same voltage print? think Plasma burn-in.

A new iOS, and apps, and heavy power demand (call it drain) changes that completely. The new iOS re-pings the battery's capacitors for responsiveness. Moves the operating ranges in different amperage. It is as fact as putting different fuel alter's your engine's timing. In a normal phone, you can reset or update the OS 50 times, leave it at 94% nightime and wake up with 90. Or shut it down at 83 and wake it up 24 hrs later with 83.

So what you called an update i call a fundamental change to your iPhone's design parameters. It's not just an update, sorry. A new OS, new everything, timings, etc. Works for most people, unluckily, not for you.

malathius, the battery gauge is built ON the battery. A dozen components, own circuit board, own sensors, own circuit breakers, built-in safety, gauges, own mini OS! And yes they interact with the iOS and report to it. So long before something is wrong with the iOS programming, many things can also go wrong - and they do at the factory- with millions of these each year. Two- four million tier one batteries are manufactured every day.

I'll agree with that. But unlike yourself. I blame the update. Not the battery. Sure. Us 6 users have been using our batteries for a couple of years. So naturally the batteries have some wear on them. But when they release an update that increases a demand on the batteries to the point of causing a problem? You can call it what you want. I call it poorly written software. Also how do you explain the erratic and what seems to be inaccurate battery gauge? That's software related. We had none of these problems before the update. It's not like Apple hasn't been dropping the ball lately with their updates. They seem to be getting worse and worse. Every update introduces a bunch of new bugs. They need to get their act together or people will jump ship. That's one reason why I haven't upgraded to the 7. I'm waiting to see what happens with the OS. Plus my phone was great until this update. Now I'm considering taking my business elsewhere. And I'm an original iPhone user!

Be it I never had any Apple training or certification, I am moderately able to repair friend's or relative's minor software glitches. Have seen them frequently, each iOS having its particular quirks,. Factory reset and clean app reset do it 90%+ of times. Have seen freezing/sluggish/barely open iPhones fixed with a diagnostic mode and factory reset. it also addresses basic drain, etc, often apps are culprit; perhaps some never closed in the background.

But what the people describe here is very unusual and far more difficult. 84% shutdown? The few times I ever saw that, in any devices, turned out (even in PC's) a hardware issue.

I hope a patch fixes your issues, but it just does not look as simple as hope makes it.

If you also accept that a company going from 10 million iphones a year to 250 million, and exceeding 500 million users has more problems than year 1, 2 or even 5, that is too simple and easy to understand.

If you wish to jump ship, you have many options:

"I'll agree with that. But unlike yourself. I blame the update. Not the battery." the reason I find it easy to blame the battery it is it being the most fragile component in any smartphone and the first reason for weird behavior. Finicky. 1-2 mm back-poket bend in the larger phone formats can toast one (and why 6S/7 have now such high torsional rigidity to prevent that). Those batteries are filled with a chemical gel that is super sensitive to myriad of factors: drain, pressure temperature, amperage, chip quality etc. The rest of any iPhone is, quite frankly, built like a tank.

Hey. At least with an android phone I can replace the battery very easily myself. ;)

More and more phones with Android OS have non-removable batteries. Most of the recent upper-end Samsungs and Motorolas do not have a removable battery and haven't for years. The only top tier phone I can think of with a removable battery is one by LG.

Thank you so much! Just spoke with an Apple Senior Advisor and he gave me some great advice...he said my battery is fine and said I did not a new battery. I gathered Apple is aware of the problem. Told him there are people on the forum giving advice about battery change and such...he said I am doing the right thing by not following their suggestions. I asked him should I get a battery change and he said it was my choice, but I really don't need it. This is an OS problem and I am going to wait and see what they come up with. Thanks again for the help with the music app.

This is an important tidbit of useful information.

Mine turned out to be the battery, but that was after Apple ran the diagnostics and found the 4+ year old battery to be shot at below 20%. For me the battery was what was causing this.

Glad there is some level of confirmation that there may also be a software issue.

Hopefully the very next update will address this for those whose batteries are coming out as seemingly fine on the diagnostics.

Like I have been saying on this forum, my battery is a Year and a half old and it was running beautifully before the 10 update. Even the Senior Advisor said my battery is great. I am going to wait until Apple comes up with an update and see what happens there. Why buy a battery when the one I have runs at 92%. He even said I didn't need a battery. It is an OS bug.

It's becoming a big joke, today I spoke to a senior from Apple, the only thing we can do is wait (and he told me to bring a charger with me all day....) and he couldn't say for how long.

The commercial lifetime of my 1200 euro phone is 24 months ,Apple has already had 2 1/2 months to resolve this issue (which is 10% of the commercial lifetime) and the only thing they can say is to bring a charger.

I will buy another phone (not Apple!) and sent the iPhone in for repair , Apple said they will send it back unrepaired because the battery tool will say the battery is just fine, I will send it in again and again until the phone is replaced (everybody with a new battery is problem free).

It's ridiculous that a 1200 euro phone only functions for half a day....and randomly shuts down.

Pass a year and 300 cycle, it is used and fair game. "great' is a relative term. I believe to him it meant that at 92%, it is within Apple capacity/cycle spec. It does not mean, in any way or fashion, that it is proof of it working properly as it is explained by Cadex and Battery University that health resistance test (i.e. capacitor saying "Hey there I can hold 92% charge) does not mean that the cell actually works. That is a separate 30-180s frequency response test that can only be done with a battery physically removed and connected to a special device. To my knowledge no cell phone provider does it at any service center. This is why, Sylvia, there are also batteries at 100% capacity "great health" yet new lemons which will not hold a long life. At 1%, that would mean 200 000 daily out of 2 million being produced. Multiple users here posted about passing the diagnostic test but proving the battery as defective once a working one was inserted. In other words, the diagnostic is a 10 foot glance at a car in a service center without actually opening a hood or taking it for a test drive.

Is it possible your battery is healthy? Yes, at 92 percent.

Is it possible your battery is defective? Yes, at 92 percent. Some new cars off the lot have issues. rare but real. Your battery could even be 90% at 600 cycles and i guarantee you that it no longer works, and cannot longer work, as new.

"I will buy another phone (not Apple!) and sent the iPhone in for repair , Apple said they will send it back unrepaired because the battery tool will say the battery is just fine, I will send it in again and again until the phone is replaced"

Next time you go at a Genius Bar, ask an advisor how many times he/she replaced defective batteries which passed the resistance health test. You will be astonished. Some batteries overheat, are swollen, leaking, fully defective, yet passing the test. Have yet to meet a single well trained Apple employee defending the test as anything more than a basic snapshot, nothing more.

It is cheaper to just buy a new battery. Problem persists? 100% warranty, you get reimbursed. Problem resolved? Great.

Belisarius, I am going to stick with Apple Support advice. Thank you for your continued advice, but I feel strongly that it is an OS problem...my 6 plus was in perfect condition until the upgrade. Thank you again, but I am trusting Apple and their advice for now.

I had luck with my daughters iPhone 5 when I did a Recovery Mode Restore

I left the phone entirely clean without putting the backup and it worked normally for about a week.

When I put my daughters backup on it conked out again with the rapid drain and spontaneous shutdown.

It might clear out something about the 10.1.1 code because when I did the recovery restore it put 10.2 on.

Maybe if you don't need your backup and can start with a fresh phone for a bit, you could get your phone working better.

The Apple Tech that ran the diagnostics said that likely the restore reset things enough to get the phone working again, but the phone had an underlying battery issue.

Anyhow... if it helps it does, if it doesn't I hope they come back with a better upgrade soon.

Good luck.
