Thanks for sharing. But do you think anyone here cares what you do? You have another think coming.

I stand corrected. Only 200 million.

More to the point - why don't any of my 3 devices on 8.1.1 exhibit this problem?

Because even though problems may be "known", it doesn't mean every single device experiences this problem. For instance, you being a smart *** on this forum is "known", but it doesn't mean you're a smart *** under all other circumstances, but probably. Bugs/Problems/Etc. are triggered by events or "conditions", and not everyone always has a situation that triggers those conditions. If you're not actually experiencing this same problem, then why don't you troll a different discussion.

I can post my opinion here as much as I want. I couldn't care less what you think of it. I'm sure there are other people who would agree with me. My job requires longer battery life and the iPhone's inability to work with a device that would allow this lessens its use for me. Your rudeness doesn't change that.

I just found this thread... appears "misery loves company". Here's 1 more to add towards the 500 million:

I was never happy with battery life on my iphone 5c, or the 4, for that matter -- in fact I had my iPhone 4 replaced twice for a bad battery. But new twist: iPhone 5c with OS 8.1 was charging okay since I got it this past spring, then a month or so ago, started losing power randomly and never charging up to 100%. After this 50% or less charge, even on the charger overnight, it would work for anywhere from 20 minutes to one hour and then go dead. Again, no matter what charger cord I used. T-Mobile got Apple to send me a new phone --same problem. Have spent hours on customer support line over this and the final word was that the initial problem was that I should have upgraded to OS 8.1.2. That makes 0 sense given that the replacement phone came loaded with 8.1.2 and has same problem. Just now T-Mobile told me Apple says I must do a restore to the default state using iTunes instead of on the phone within Settings. And then do NOT restore from my backup until I know whether it has the same problem. That could be months for all I know. And am I supposed to just manually enter all my data and re-download my apps? Even though I religiously backed up my data regularly on iCloud. NOT happy -- in fact REALLY angry. I will post again with any additional findings, although I am not being paid to do testing by Apple (I SHOULD BE -- no time for my real job anymore).

addendum to my screed:

My biggest problem with all this is the old saying "no good deed goes unpunished".

I had to make a critical (not emergency, but still important) trip upstate to stay with my dad this week, as he has been ill, and so I was more than annoyed that I had no working phone and no one seemed to be able to come up with a solution. Not T-Mobile and not Apple. I have now spent 2 solid days on this and expect much more. Thus my angry post to Facebook and the appropriate Apple forums. I went to see Jeff Jarvis speak at the Art Directors Club a couple years ago. If you don't know him, he wrote a book called "What would Google Do". which I recommend but it takes only about a quarter of the book for him to make his point clear.

In it he describes how he resolved a shamefully bad customer support issue with Dell by posting his problem widely. Once the right Dell people saw it, he received radically upgraded support.

That's my hope.

Scanning these nine pages of testimony, I have concocted a model that the message is generated when the iPhone is pulling too much power. Reducing the power demand by, e.g., killing apps and turning off some functions, may avoid the message. I'll try it.

On another topic, someone got an encouraging result by changing the charging port. Is that the charging port on the iPhone or the USB port on the computer?

They meant the dock connector or Lightning connector on the phone. This is not a good idea as a DIY project, unless you are experienced in working on microelectronics, and you are willing to give up warranty coverage (if you still have any) and the opportunity to get a discounted replacement for the phone out of warranty.

Yes, a connector with a bent, broken or corroded pin can cause this, but it is one of the rarer causes. The most common cause is dirt in the connector. And for devices that use the Lightning connector use of a non-certified cable or a damaged cable.

Your thought about power consumption is interesting, and a possibility. But only if you are charging using a computer. Apple wall adapters can supply enough current to overcome any app drain on the phone.

I too have this problem and it seems to be random, regardless of cable, although Apple ones are fairly consistent about avoiding it. Swapping cables and/or USB-AC connectors usually fixes it until for me until the next random iteration.

I'll try it.

Results are inconclusive. Closing all apps (double-home and swiping up), and turning off LTE and Bluetooth, seem to delay the message, but not overnight.

I notice that iTunes can sync fine even after the message, and that charging is adequate. So, for me, it's just a nuisance message (and "twonk") that obscures any texts that may have come in.

I ALSO notice that wiggling the USB connector that goes into the computer socket causes power-fluctuation effects, including the subject message. Hmm. Now there's something to show my hardware guru. Anyone else see this?

--Gil

No matter how you slice it, that message indicates a hardware issue. If wiggling the USB connection to your computer brings it on that should be patently obvious that it's hardware. Likewise, wiggling the Lightning connector or Dock connector. The phone checks several things when you connect it:

• That all of the contacts on the phone end are connected
• That all 4 of the contacts on the USB end are connected
• That the device at the USB end has posted a signal saying it is iPhone compatible
• That the cable is intact and has no broken wires
• If it's a Lightning cable, that it it contains the 3 genuine Apple microcircuits in the Lightning connector - these can be either because its a Apple manufactured cable, or if its a 3rd party cable, that it is one that Apple has certified

The first condition will fail if there is dirt, moisture or a broken pin at the phone end. The second, likewise for the USB connection (not all USB devices require all 4 pins, but the iPhone does)

I finally found my problem. It kept beeping when I was handling the phone while plugged in. I thought emails were coming in or something and then I saw a news comment on flashlight apps stealing your data. Thought I had a virus. Then I saw a Nike + iPod app in my settings, but not on my home screen. Thought it was a trogan, but I must have turned it off in the settings. Got to this thread and it seemed to point to hardware. Why was I always getting 90 something percent charged after being plugged in all day. Since I was using the phone plugged in, it kept beeping and giving me the device not supported error. So I wiggled the cord below the connector and it beeped continuously. Broken cord. Plugged in a new Belkin cord and one beep and it went to 100% and does not beep anymore. I guess I don't have a virus and my phone is silent.

I don't believe this is a hardware issue - I'm using the "in the box" charger and cord that came with my iPhone 6, I've triple checked the charging socket and plug, and it will charge if I shut the phone off. However, I consistently get this message every night when I plug the phone in, but if I leave it plugged in, then unplug and replug it about two hours later, I get the normal charging screen. This happens every night, so I'm pretty sure there's a conflict somewhere in the software or firmware (it seemed to start after the update to IOS 8.3). I was hoping this might be corrected with today's update to 8.4, but it doesn't seem to have changed anything. Hope Apple figures this out, as it's a real pain to have to keep plugging the phone in until it actually starts charging.

You don't have to believe it, but it is a hardware issue. But if you want to assume that it is a software issue you can continue to live with it for as long as you own your iPhone. To fix it you will have to drop your belief that it is not a hardware issue, and follow the troubleshooting steps that have been posted over and over and over and over...

Well, maybe you didn't read my message, but I have tried just about every hardware troubleshooting suggestion on this and other threads. I don't see how you can say it's a hardware problem when 1) I plug in the cord and get the "not supported message"; 2) leave the charging cord plugged in; 3) turn the phone off; and 4) when I turn it back on, it has taken the charge. Does it magically resolve the hardware problem by shutting off the phone - don't think so.

OK, you win. Live with it. Or take it to an Apple store and let them explain it.
