iOS 10.1 Battery drain

okay, no offense, although i did not expect any answer from apple, but from the original poster, who linked the rumors about 10.3; probably my last sentence could be misunderstandood by apple. Whatever, thanks for your answer, but this all i have read already, i am following the topic since the 13th page (we have now like ~90?), in hope of some breadcrumbs of a software fix.

As i see, the problem still exists, and not only for me. The replacement battery is not Apple's, and still has something like 2-3 months of warranty, although i am mostly sure, that this is not the battery's fault, rather the iOs. As i already wrote, my previous, faulty battery was draining fast, but there were NO sudden turn-offs at 15-20%, the drain went steadily to the zero percent.

Anyways, I will wait for the 10.3, if the problem persists, I will try to get an earlier iOs, if not possible, then (blasphemy) a jailbreak, and then i can be sure, that it is not the battery. But in this last case i'll have to reconsider my upgrade plans to a i6s

Genya, you were getting terrible battery life. My Gf, beaten old iPhone 5 with iOS 10 lasts a good 10+ hours with moderate to heavy usage. Your iphone 5S has a better processor, twice as fast, more efficient, better NAND and RAM, and should last you 20 hrs or so. 10 with social media.

And if indeed you placed inside a non-Apple battery, all bets are off. You can check 3d party macworld forums, they never work well. They may be 1/3 of the price but also 1/3 of life.. You are welcome to google NuPower battery issues. Sold via OWC, these 3d party are the cheapest of cheap batteries sold at pretentious rates and rated for months of usage, not years. tried them, garbaged them, it did not even matter getting new ones for free, they were crappy, ad crappy MC microprocessors on them.

no, no, my 3-months old battery lasts quite good, from 100 to 20 it lasts like 12-24 hours, depending on usage (last time it lasted for like 48 hours, in standby), but when it reaches 15-20%, it turns off without any warning (iOS 10.1.1). My previuos, faulty battery was lasting like 4-6 hours (from 100% to zero, no unawared turn-offs, iOS 9.x). Beside this, i am not using any massive apps, sometimes viber, rather rarely messenger. Beside this music, bank-transfers 1-2 times a month, and some facebook-over-safari. Nothing new on my phone.

I saw your informations, answered it, but my comment was also removed 😉

so you say, hundreds/thousands of batteries delivered with genuine, brand new phones are also crappy, and shut down under 20-30%? I think i am misunderstood again, so:

- old battery, apple, first 2 years, from 100% to 0%: 12-16 hours, after 2 years 4-6 hours.

- new battery: from 100% to 20-30% lasts about 12-20 hours, then it shuts off suddenly, no warning, at ~20%. I never said, it lasts only 4 hours, all i said was, that it shuts off at 20%, and this issue started when i updated to 10.1. And 90 pages of users say the same

This problem is likely a battery issue as much as anything. The tech at Apple told me that upgrades sometimes reveal an underlying issue when the upgrade is installed. This certainly is our experience. Our battery was shot and failing which was why the battery indicator showed the phone rapidly draining with Sudden shutoffs. The battery and indicator were unstable and failing at below 20% reserves. I did the Factory Restore which allowed for things to come back to proper function for a time, but every time I put the backup of data back on the phone, the phone would start with the erratic behavior again. Apple ran their remote diagnostics on the battery. Mine was at less than 20% and failing.

I like the way you came back 180 degree to incorporate the battery-fail scenario I first hinted to you. There are surely several types of issues going on:

1- Battery drain, no sudden shutdown, good battery life (90+)

2- Battery drain, sudden shutdown, good battery life (90+)

3- Battery drain, no sudden shutdown, declining battery life (60-90)

4- Battery drain, sudden shutdowns, poor battery life (anything below 60)

5- No battery drain, sudden shutdown, good battery life

6- No battery drain, sudden shutdown, declining or poor battery life

Perhaps a patch can fix issues for those with Scenario 2, 5 and 6. What we do know is that continuous battery drain, or anything 1-4, = rapid discharge. Rapid mAh discharge kills Li-Ion batteries. Some readers dislike technical jargon, but it is reality. A leaking fuel tank will never get your car far.

Interesting that the PG technical data, plus facebook, or PG and Navigation are sufficient at 60% drain to reduce a Li Ion cycle life from 300-500 to 100-300 tops. I had no idea that Battery University folks were already studying the Killewr battery App scenarios..

I disagree with Belisarius - if an app is causing excessive drain and potentially prematurely ending battery's lives, then it should be pulled from the App store.

This is what I thought happened when an app was submitted for publishing, it was tested and checked to ensure that it worked and caused no damage to the device.

Much as it would pain me to stop playing the game, I would rather my phone's battery not die!

Belisarius, looks like Apple have their work cut out for them in terms of batteries, I have just read the poor battery life reviews the new MacBooks are getting and the fact that Apple removed the "Time Remaining" battery indicator on Sierra.

Adrian, you are not at all disagreeing with me. I never made any comments about App development and App stores. All I did is forward you the Pokemon Go data which shows it at 28% with cycle impulses a brutal demand. Add to it GPS/Navigation (as people use both when playing) and they are frying their own batteries. You agree with that.

The App development process, and trial, is outside this forum purpose. But there are 22 mobile iOS platforms, 500+ millions iPhones, 100 million plus Android and iPhone Pokemon Go players, etc. The App developers likely checked iOS functionality, not hardware impact. And no, it is not Apple's role to simulate 22 hardware configuration versions.

Am super glad you are reading on batterie in other areas. I see how your approach to the issue has become more technical.

but, user beware. PG is an energyvore monster. And the older the phone, 6, 5S and 5, the more the load it places on the ARM x CPU, antenna and the battery...

Hello All! I just wanted to follow up with my current success story (4 days so far). I have an iPhone 5 and had the crazy/sporadic battery drain/shut off issue after updating to iOS 10 and up. Maddening to say the least. The Battery Life app had varying responses that my battery was on the low side of good to bad. I dropped Apple Care a long time ago as it got to the point that were anything to go horribly wrong I'd upgrade anyway.

Anyway...I decided to try and replace my own battery. Battery plus tools $25 from that site with the smile on the delivery boxes. $25 attempt vs hundreds. Either way I figured I might end up having to choose a new phone. Well, I changed the battery successfully and so far (again it's only been 4 days) my phone is behaving as a phone should. No sporadic battery percentage jumps, no miscellaneous cut offs, no unusually hot phone backing. The original battery had a "born on" date of 2/2014.

This was all I did. No factory resets/re-installation of any of the versions of iOS. I did go hunting for any hidden battery drain in the apps I have such as location settings I hadn't turned off and things of that nature. Only found where Instagram was linked to my FB account (which FB is usually in logged out state). Unlinked, didn't seem to behave any differently so can only assume that wasn't a culprit?

Here's hoping this was all it took for my particular circumstance. I still check my phone periodically just to make sure and yes, for the first 2 days it really did shock me that with the same usage as before the swap I had considerable battery life left. Even friends were amused by my reaction but hey, when you really don't know how long you'll have an operational phone...I hope everyone else finds resolve (and I hope this continues to prove a success for myself)!

As much as it is appreciated hearing that replacing the battery work, I would use a soft foam roller to smack and ask you "what did you do?" https://www.amazon.ca/GENUINE-OEM-ORIGINAL-STANDARD-INTERNAL/product-reviews/B00 DD0QF9Y/ref=cm_cr_arp_d_hist_1?showViewpoints=1&filterByStar=one_star&pageNumber =1

Those battery kits are 20-25 as you say, but I picked one example of a third of users with poor effects- on Amazon. So in the world of batteries, there is Ladas, KIAs, Hondas, BMWs and Bugattis. The 3d party ones tend to be Ladas and only last a few cycles. Same as the NuPower battery pack. Unless Genuine Apple (about 80$), they are the lowest grade battery possible. If it works for you, great. I just hope it does not drool liquid inside it.

"so you say, hundreds/thousands of batteries delivered with genuine, brand new phones are also crappy, and shut down under 20-30%?"

Genya, the Apple released industry numbers are 2.7 to 3.5% . Apple hopes to ship 100 million iPhone 7s this year. If you take the highest average last 3 years, say 3%, = 3 million iPhones. Out of these some will be battery related (as the 6S recall- and they were new!) Are these numbers acceptable to you?

Add to it 6S being produces, SE etc 250 million+ per year or 9-10 million phones. Hence why the 488 apple stores are stocked with a very smartly designed parts supply chain to anticipate for a forecasted number of repairs. tehy day of a new phone launch, parts arrive at the same time as the new phone.

Why the 30% If you go at Battery University, 30% is the magical Li Ion health threshold. A cell that looses ability to store properly does that below 30%. If affected, its ability to produce power stops at, you guessed it, 30%. It is an exponential down-curve. Power discharge is relatively steady until 30%. Then it drops nearly vertical.

But if you take at face value just the 6S affected recall, then you already answered your question.

Like I said, keep posting relevant good info. It is the presentation of questioning peoples motives and intelligence that often takes away from people taking-in what you are saying. Good Synopsis above BTW.

Anyhow... at this point after what you have informed me of and what the tech at Apple confirmed.

1. Attempt a Recovery Mode Factory Restore; if not fixed... step 2.

2. Have a Battery Diagnostic done remotely; problem gets logged. Checks other potential hardware issues.

3. If battery is bad; replace it.

4. If battery is good... 80-90%; Not sure here how someone should proceed, but their problem will be logged.

Much as it would pain me to stop playing the game, I would rather my phone's battery not die!

If you remember, there was a time years ago when watching a single movie on a mac or iPhone drained them pretty fast, right? not anymore. Since the CPUs (and ARM are top industry grade) and GPUs are hardware optimized, this is why I get 12-15 hrs of nonstop movie play on the MBP. helpful when traveling. The drain/discharge is hardware optimized, most of the load done by the CPU GPU etc. The battery sees a slow drain, despite videos beign graphically demanding.

Pokemon Go, to all indications, is neither hardware nor software optimized. Even Nav/Apple Maps Google Maps are GPS Chip optimized, so they will drain faster, in say, 10 hrs. But not PG. it is just a pig, forcing your battery to discharge rapidly and below those safe thresholds you saw at ** charts. It is the same on any Android phone as well.

Facebook used to drain my GF's battery. once she removed it, problem gone.

With millions of Apps in the App Store, it is impossible for the manufacturer to optimize each one, physically, in each chipset withing each 22 supported mobile iOS platforms. Then the Apps change with each update. So you get the scale of the limitation. Nav, movies, GPU optimized games (and why at Apple Event Mr Schiller introduces the game developers which worked with Apple specifically to optimize their games, work very well. So EA top games for mobile are generally optimized. It costs millions, but the partnerships are public knowledge. Outside this, user beware.

Why the 30% If you go at Battery University, 30% is the magical Li Ion health threshold. A cell that looses ability to store properly does that below 30%. If affected, its ability to produce power stops at, you guessed it, 30%. It is an exponential down-curve. Power discharge is relatively steady until 30%. Then it drops nearly vertical.

I concur.

This is my understanding after I have read the information.

This is my personal experience with my Daughters iPhone 5 which was below 20% and completely erratic after the update 10.1.1.

A Recovery Mode Restore got it working again for a week and it seemed to hold its charge for 30 hours, but the battery indicator was still a bit wonky. Installing the backup again brought on the unstable behavior from the failing battery.

Getting Apples Support app and Chatting with them via the app allowed me to have them run diagnostics on the iPhone 5 remotely. The report came back as a failing battery with less than 20% residual capacity. That is well below where instability begins to occur.

I am surprised it hadn't happened before. But the 10.1.1 update revealed the flaw in my machine. The Tech at Apple summarized this for me as well.

I'm definitely keeping tabs on the battery (particularly due to the reason for the swap in the first place). And very much aware that the one I got (ScandiTech for all it's worth) probably won't keep the phone going another 2.5 +/- years (unless I just got super lucky somehow). My situation was just really had no desire to put much money into this experiment nor to go out and upgrade (ie: purchase a new phone as personal preference not too impressed with currently available options for the cost - any manufacturers). If the battery fails, and more so if it kills the phone, upgrade time it is I suppose. Just trying to buy time til next gens of various phones are released.

BTW: really like the auto analogy (much more my language than phone batteries) 🙂

"It is the presentation of questioning peoples motives and intelligence that often takes away from people taking-in what you are saying."

Remember you only see a portion of the items I responded to. Some are quite insulting. Apple removes them before you even saw them. A few users then retone and retone the insult until it makes the cut. And when the speculation and attitude reached a very poor destructive level, it gets the required pushback threshold and I reply. To date, none of those replies have been deleted, even though the original post that triggered my response was deleted.

You may find interesting to google news the next iOS update.

I can go the auto analogy route quite far, from Lada to Veyron. Some users found it irrelevant to the forum. But here is another one. Let's take a cold country with a month 0F to -30F. European car owners flock at the dealership with electrical issues. Even though not Li-Ion, the question was, what was going on?

European cars have larger more powerful batteries in the trunk. Below -10C they never charge. Nor does Li Ion. Bavarians, for example, need 30+ miles driving before the alternator is switched to warm the battery. And since most people drive daily, those batteries, taxed by Nav, seated heats, wheels in car apps, are always drained. Below 30%, the auto batteries stop powering key electrical system e.g. power steering. The answer for me was to lower the ski trap and let hot air warm the trunk, and plug the battery as often as practical. With the freely provided trickle charger I had not used initially. Zero problem since.

Front car battery owners get some power as their batteries are partially heated by the nearby engines. But they only last 4 years in cold climates, 140$ or so. Powerful, nicer cars, those batteries run 500$ so running down an expensive battery is not something I opt for. Optimized use is the smartest way to save money.

So the users here saying their battery shut down due to outside cold are confusing the issue, as we do not know if it usage versus bug. At high cold the batteries can shut down even at 90% to protect the circuits. At least cuddos to Apple for building in a cold and heat circuit braker.
