iOS 10.1 Battery drain

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.


So it goes from zero charge to 30% in the time it takes to reboot? Strange.


2 - Shutting the phone down at night with a good 80% charge, it won't reboot in the morning due to no battery charge. I plug it in and its back to 30% in a few seconds.



Thanks for any suggestion in advance.

iPhone 5, iOS 10.1

It is a giant moving train- hundreds of millions of batteries are made each year, 100s millions of management controllers and microchips, etc, and all being moved by the ton/second towards all phone makers. The very halt to implement newer / better would cost anyone billions. So yes, in this competitive environment, economics play a role. It is said that Samsung skipped a one month certification process for the GN7 batteries and beat Apple's 7 release, and the rest is history.


We know Apple always seeks to innovate (https://www.wired.com/2015/03/apples-new-battery-tech/) . Zoom forward today and CR just slammed the new MBP battery as inconsistent.


G3 3 Li-Ion is expected to x2 capacity http://fortune.com/2016/08/21/mit-battery-spinoff-market-2017/


Li-Ion has a lot more potential at the nano- level- basically 3d print Li Ion filaments of nano size (vs current plate technology), condense them tighter and they can hold x20 to x100 more power. Then again, it is highly volatile and a single cell now can catch fire and burn through a plane floor. Imagine x20...


Then again, it raises the issue, the mad rush for mass-production, whomever makes a tiny error, the consequences are major (17Bn market loss for Samsung).


Apple is spending a lot of money on replacing current batteries under Apple Care..So yes, Apple is seeking to invent in the field due to mobility, rumored Apple Car (icloud connected) and much more..

While we are digressing on battery technology, I reckon this is the way forward:


http://fusionforenergy.europa.eu/understandingfusion/


In 1985 I chose to study Nuclear Engineering at Queen Mary College, London, starting in 1987.


Unfortunately in April 1986, Chernobyl happened and the only two Universities in Britain which offered the course (Queen Mary and Manchester) scrapped it.


So, I did Mechanical Engineering instead, and in a roundabout way now I have my own I.T. business.


Used to think of computers as a hobby since my ZX81 in 1981 and loved it, but as Confucius said:


"Choose a job you love, and you will never have to work a day in your life."


So anyway, technically I don't work anymore.


🙂


Forgot to wish everyone a Happy New Year.


Come on Apple, I know they say silence is Golden but this is ridiculous!

Sounds like a great deal, you are trully blessing them with gadgets.. 🙂


Umm, no xtra suggestions not for iPads. They are very reliable; due to indoor use, longer life and much larger battery- except kids break screens. A screen film helps.


Only suggestion is to ensure keeping the original receipt if a CC. Visa and MC offer an extra yr warranty so that makes it to 3 years.

Yep original iPad 2 is a tank. Keeps on going. No problems. Lasts forever on the Battery still.

Thinking I will get the Smart Keyboard and Zagg Invisible Shield. Should be good for the screen. Kids have to be sitting and "check out" the iPad from the daddy library and bring it back when their allotted time done. A very formal affair. Has worked well so far during the long 5 year life of our iPad 2 + with liberal dose of extra luck for lax moments in the system.

Amex gives an extra year against defects...not damage but still nice. Automatic coverage 1 year beyond Applecare + warranty too. 3 Years is nice.

Led to this thread by an article reporting on this problem. Just want to add another data point that I too am experiencing this problem. I have an iPhone 6+, 2 years old and no issues with power management until installing IOS 10. Now I have the 30% problem, with the phone shutting down and not booting up until it is connected to a power source. Upon restart it shows I actually have somewhere around 37%, though I've seen this happen at various capacities in the 20-40% range.

Jan 2, 2017 6:19 AM in response to Mjolcresure

Seems to be a lot of irrelevant chatter on this thread. Can we please get back on message? Am I right in saying, Apple released an update which has made a lot of people's iPhones unusable? They have not formally responded on this issue? They are letting users try to get a fix themselves?


My 6 has been an a nightmare since ios10 installed. In last few days it's just been turning off at about 80%! Never been this angry with a company. Apparently one unhappy customer tells 20 other potential customers about their bad experience (that was before Twitter!)


Can anyone please tell me if there is a generally agreed way forward on this thread (without me having to read all 80 pages?) I'm about to do a factory reset. Has anyone had success with that?

Summary:


1) IOS 10 drains battery significantly more than IOS 9

2) IOS 10 may be damaging batteries

3) Factory reset does not help if IOS 10 has damaged the battery, new battery required

4) Apple have said nothing but have released diagnostic tools on IOS 10.2 so they can troubleshoot the issue, in other words, they have no idea either

5) A factory reset may have fixed a small number of handsets

"Hi Evagorasc, Belisarius is right in his main argument: Batteries are consumables and degrade according to the way they are used. However, he only focuses on that, he has obviously not felt the realisation of having upgraded to IOS 10 and his battery suddenly drains and goes bang. Like we have, to us it is obvious, IOS 9 = fine, IOS 10 = dead.


The proof is that in an unheard of turn of events, Apple released in depth battery diagnostic tools in 10.2."


Adrian, I am beginning to think that the Sep 2014 launched iPhone 6, and the new thinner larger battery format. As of Nov 2016 and over 500 cycles, they are done. Period. Two long years of heavy usage-as yourself admitted.


So two years into this process, yes Apple released 10.2 diagnostic. But I believe it is to address the complaints of battery issues failures and identify them as they were building up. But I was aware of a small number of people complaining since iOS 7, and yes, iOS 9 with iPhone 6 and 6S.


Unfortunately a technique called Competing Hypotheses eliminates the iOS as a culprit. Your hypothesis that iOS causes it must be universally applicably yet it is not. Hundreds of millions of iPhone users have no issue.


An iPhone 5 whose battery I had replaced, it was about 6 months old and acted with iOS 7, the day off. Apple replaced the battery. the iOS did not kill it- it was justa poor battery. The replacement worked perfect for 2 years after.


It is more like Your battery is defective and hanging in with iOS 9 hanging up. iOS 10 exposes the flaw and it dies in 60 days. Or the battery stress of install and maybe some fast draining apps exposed again an inherent weakaness.


Am I right in saying, Apple released an update which has made a lot of people's iPhones unusable?

Not at all. Over 500 million users of iphones 5 to 6S updated successfully. That was repeated several times by Apple while monitoring iOS 10 deployment. Your particular 6 battery has likely a shelf life of 2+ years, approaching 600 cycles and likely just died as it was supposed to, as a consumable.

Adrian,


1) +1 All iOS, generally, drain more. The Arstechnica article explained it. http://arstechnica.com/apple/2016/12/explaining-the-battery-life-problems-with-t he-new-macbook-pros/

2) -1 Any usage damages a battery, including Android. It is speculative. And hundreds of millions upgraded successfully. The best yet is iPhone 5 users with better iOS 10 performance than 9- and far older batteries. But they were different batteries than the post 6 generation.

3) +1 No factory reset will ever repair a damaged battery cell. That is known. The MC reduces functionality with each cell error report. But the battery is more likely to just die than any particular process to cause it - except the flashlight.

4) -1 Pure correlation. Battery issues have mounted steadily - in their small 0.0004% or so range, since iPhone 5, and iPhone 6 - larger thinner batteries, more bendable and why the 6S was reinforced. Any diagnostic tool has been overdue for 10 iOSs, in my opinion

5) +1 A factory reset and clean install resolves numerous minor glitches. clean install, new index, new apps install.

Jan 2, 2017 6:44 AM in response to AppleYoda

Can anyone please tell me if there is a generally agreed way forward on this thread (without me having to read all 80 pages?)

1- Restore phone to factory defaults, do a clean install. If having the luxury, try 24 hrs monitoring

2- Do your image restore. Apps should be installed cleanly.

3- Monitor. If any SSE, your battery is probably defective. Very much normal if it has exceeded several hundred cycles.

4- Get a free battery replacement (Apple Care) or risk free paid for one

4- Get phone replaced. Adrian had success with that.

Jan 2, 2017 6:53 AM in response to _Belisarius___

What are you talking about? Good lord alive. I didn't say it effected everyone. But based on the length of this thread and others it has certainly effected a large number of people. A straw pole of my colleages/friends/family found 3 others out of about 10 or so have had battery issues following upgrading to iOS 10.


Please don't talk nonsense wrt 'consumables'. There is a definite link between IOS 10 and battery drain/damage. My iPhone 6 is 18 months old and the issue started a few months ago at the very moment I upgraded. My phone initially ran really hot then the battery issues really kicked in. It doesn't run hot anymore....in fact it doesn't really run much at all. Fried by Apple!
