iOS 10.1 Battery drain

About the same here. I don't think our batteries are really being drained though. Today my phone went from a 95% charge to a 1% charge. I plugged it into a charger and within a minute I'm back at a 81% charge.

I recommend reading the posts from members that experienced the same, had their battery replaced, and issue is gone. The last two, in the recent 3 pages, even used the same image- no more issue. So much for the iOS drain theory.

Just drain does not come with shutdown. Any power cutoff usually means hardware.

Battery replaced on December 25th.

So it's been 9 days.

I have to report that since replacing it I ...

-have had no fast drains whatsoever

-have had no shutdowns whatsoever

-have gone from 40% drain in the first 90 minutes of the morning to 10% or less

-have been able to go all day and still come home with about 70% battery remaining

I would wager to say replacing my battery has solved my phone issues.

Batteries Plus, $54, FTW.

Too all forum readers - a generic statement.

Mounting evidence from users whom replaced their battery points out to 100% resolution of the mysterious shutdown issue. As much as I sympathize with the sudden inconvenience of having to replace a battery, no words can express the strong discouragement I have towards 3d party fake-Apple batteries which flood the market out there.

- The may be 1/2 1/3 of the genuine OEM price but will not performs even close to the real hardware. No 3d party fake 'like Apple" or "OEM" dealer has access to the lowest price, which is Apple's 300 million units/year bulk.

- 3d party battery user reports include short life,overheating, inconsistent performance and, worse, iPhone fire

- Genuine OEM batteries come with special packages. An authorized retailer can show it to you (and you can always check with Apple).

- Part of his relationship with Apple, the authorized retailer sends your defective battery back to Apple. So that dead battery serves a final purpose, indexing and further evaluation to determine common denominator. That is how warranty recall cases are build. 3d party vendors, or users replacing their own batteries, do not.

Years ago I have myself done the 3d party battery thing. After discovering that the 3 year warrantied "better than Apple" batteries never lasted more than a few weeks, I found out that:

- They only lasted weeks to months at most

- I had to pay for return shipping

- I could not send them by plane (dangerous goods) and if I tried, own risk of non-delivery

- Recommenced the cycle with the replacement.

As for local vendors, such as in the town I am in, they are open as to showing their authorized status, and OEM parts packaging, replacement screens or battery.

Best Buy is another known Apple authorized battery replacement place.

Hi Belisarius, hold your horses.

The shutdown issues may have been resolved by the new batteries but the root cause has not been identified.

It all happened after IOS10 so it may well be that IOS 10 will drain even new batteries after a period of time causing shutdowns.

My opinion is that Apple will release a fix quietly before new batteries are affected thus avoiding any possible litigation.

Come on, be honest, why on earth would they release battery diagnostics on 10.2 so soon after we all started reporting these issues.

I know at least 5 people who handed their iPhone 6 phones in after IOS 10 because their battery was just draining before their very eyes.

Adrian.

I agree. My 6 plus had zero battery problems until the minute I updated to 10.1. After that I could watch the battery drain. But only after it got under 50% usually. It's erratic though. Some days it would perform pretty normal until I reached a certain battery percentage. And then I could see it drop from 40% to single digits within a few minutes. I've had it showing 30% and then just shut off. As soon as I plug in the charger the battery would show a 50% charge. The last one I went from a 91%charge to a 1% charge within 5 mins. Then it shut off. When I plugged in the charger it was at 91% as soon as it came back on.

Last night I tried a few things. I removed my Facebook app because it's been known to eat your battery. I also noticed an unusually high percentage of batter use from my music background usage. I was also using a Mophie case. After removing the Facebook app and disabling the online music function and using the phone outside the mophie case my phone is performing normally. Good batter life again all night and today so far. 5 hours of use. Music/phone/text and safari and I'm still at 88% as I type this. So the whole "replace your battery" theory is a bust. At least for me.

Hey Adrian,

If you are willing to assume, or take it as accepetd fact, that over , lets say, 450/500 million iphones out there with iOS 10 have no drain, it just automatically invalidates your hypothesis. Analytically it has to be universally applicable...

diagnostics- myself and many others (macworld, gizmodo arstechnica) have submitted feedback since iPhone 4 requesting a diagnostic tool. Repeated it when my new iPhone 5 battery died. And with the iPhone 5 battery isue forums this was a longtime wish.

Finally, right now are at the 26 month since the new 6 format was launched. Hundreds of millions of iPhones 6 have passed the 300 cycles. This is new as before the 4 and 5 iPhones had different screen sizes and battery cell, and demand. So call it a battery-life bubble happening now. All these hundreds of millions of batteries have peaked and new phenomena are happening as they did to you.

Also check out the scenarios i listed 4 pages ago. Some have drain but NO shutdown. all this to say it is absolute scientific nonsense madness to generalize an iOS drain as exicable to all malfunctioning iPhones with shutdowns. Then those that resolved it by replacing the battery WE KNOW it was not the iOS. It was proven absolutely as the replaemeny batteries no longer exhibit the behaviour. When you have other users posting back to admit it was not the iOS after all, you have no reason not to take them at absolute value.

Finally plse reread my prev post on resistance testing and limitations on battery health reporting.

Also beware of using high certainty statements, e.g. 'iOS 10 drains...' They fail any argument, scientific methodology and do not exist in any methodology. in critical thinking and analysis, from technical all the way to intelligence work, certainty statements never pass the rebutL stage.

HI Malanthius,

How did you disable the online music function? At the Apple Store the Genius rep said my battery is fine. I did a restore and I was back to the drainage. I did remove a lot of unused Apps and that helped quite a bit. I will not replace my battery since it is fine...the draining problem occurred when I upgraded to 10.1.1. Apple is aware of of this situation and hopefully an update will happen soon. Thanks for your help.

" I was also using a Mophie case. After removing the Facebook app and disabling the online music function and using the phone outside the mophie case my phone is performing normally.

At least for me."

Thank you for proving my argument and conclusions. By removing facebook and the mophie case you fundamentally- no 'Buts' or 'ifs' altered the power demand and charge/discharge demand on your battery. You altered the voltage in other words. Please refer tobasic battery university ampages explaining how apps=power demand=voltage.

Consequently high likelihood that your battery is defective since it cannot handle peak demand.

as othersalready admitted iOS may have simpky exposed the battery flaws and it failedthe iOS testing. A new battery even with facebook on will give you reasonable life.

Also please refer to ** pokemon go example of APPS KILLING BATTERIES.

Hey Sylvia. Go to settings, then Music. Turn off "show Apple Music, turn off Genius. And turn off Cellular data. That's the only settings I was able to find and turn off. That and removing the Facebook app seems to have worked for me. 6 hours of use and I'm at 72%. I think that's pretty good. Not using the Mophie. I want to see what the phone does when it gets down below 30%. Seems to be functioning normally. Amazing without replacing the battery! ;) Nobody is going to convince me to replace my battery when the phone was performing normally until I did the update.

How do you figure my battery is bad when I am not using the Mophie. Removed the Facebook app. Turned off music functions. And I have normal battery life as before the update? Sorry. You are wrong. The update is what caused the problems. Everything was fine until the update. Unless you think somehow believe it was all a coincidence. :D

"How do you figure my battery is bad when I am not using the Mophie. Removed the Facebook app. Turned off music functions."

Because you had to remove the Facebook App and music. The girl's iPhone was drained rapidly by Facebook. She removed it, problem is gone. However, hers is an iPhone 5 with a tired battery at 750+ cycles, which we know it is done. We will replace it soon. Have asked around friends with newer iPhones 6/6S, with Facebook Whatssup etc, iOS 10 and no issues whatsoever running it as before.

By removing Facebook and fiddling with it, you altered your device's amperage. That my friend is what is called a frequency response test. With less demand your device has less resistance (or what you would call drain) explained at the 3d link.

I also attached the PG example with CNET as a well known neither hardware nor software optimized app. It is wrecking havoc both on Android and iPhones; stressing the batteries and reducing their lives significantly.

So when a new operating system is installed and re-pings the battery for operating range, it fails.

Again, remember that a battery can have a 90%-100% capacity/ 'healthy; resistance test, but still be fully defective at factory. Those tests are now on their dying industrial legs (frequency testing on its way). That was explained in a previous post.

Also remember that drain can happen; e.g. using GPS drains these faster; but shutdowns are not normal. And also. any high drain kills batteries.

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.

My 6 has been doing this shutdown thing since the 10 upgrade and I live in a warm climate. For the most part I think the bulk of the issue has to do with the OS rather than hardware. My current phone has never been overheated or in freezing conditions; it dies at 41, 36 percent and can last a very long time on 1 percent - though when you plug in it in a more accurate percentage shows.

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. Especially since my phone had great battery life before the update.

rose, climate is one possible variable. Any for the following can affect a battery: heat (one summer day in the Iraqi desert), cold, repeated outdoor stuff. More often though, poor optimized apps, Pokemon Go/Facebook, drain, as well as factory issues (a few million a year leave factories defective). The #1 indicator that a Li Ion battery has issues is any shutdown in the 30% range, that figure being the anchor point for Li Ion health. Be it that particular battery could still have 86 or 100% health, 30-40% is the key spot. If some patch can help with that, all the better. If not, your options will narrow.
