Q: iPhone acts odd, crazy, touch screen, random behavior, while charging

For me it only happens with one specific charger and I am sure it is a Genuine Apple one

Then that charger is probably bad.

I'm experiencing the same behavior with my iPhone 6 Plus--with an Apple iPhone 5 charger designed in CA and made in China--that I just used with the iPhone 5, an iPad Air II, and my iPhone 6.  Once I read this thread and unplugged the charging cable, the erratic behavior stopped.  The behavior was such that it seemed that someone else had remote access and control of the device.

Yes, it can certainly be rather disconcerting.

Ok this has been happening to me since I first set up the phone, and it happens when its plugged in OR not plugged in, doesnt matter.

It started by always randomly switching apps, mostly opening the appstore. Now it types on its own, switching in and out of text conversations, and deletes text after I type it. I cant do anything without this thing deciding what actions its going to take on its own.

After reading this I move a few apps around on the home screen to see if it was the location of the appstore app, well see but I think I am going to get this thing replaced. So much for QA Apple.

I'm seeing the same thing.

My iPhone 5S is kept in a Mophie charger, which I charge via Micro USB. Hooking it up to my MB Pro Retina 15" and touching the iPhone screen while charging makes the phone go crazy. It's funny to see that when you open a new note, it will start to type random characters and do all sorts of things in the note.

This must be some current flow or something that makes the screen interpret things differently.

I may have charged my Iphone 6 plus on a non std charger.

Next day called my brother. Heard my brother's voice message so left a message.

He did not recieve the message.

Someone else got the message. They returned a call based on that message which left a message on my brother's phone and not my phone.

This just started happening to my 5S 64.  Charging was/is not involved.  The descriptions of it being like someone else is using the phone remotely are apt.  That's exactly what it's like.  I've determined that if I ever-so-slightly "flex" the phone by grabbing it at the ands and twisting (just a tiny amount) I can exacerbate the problem.  I have babied this phone.  It's never been dropped and spends its days in my breast picket in a BookBook leather case and its nights on my nightstand.

I've done a full backup and restore to no avail. 

Weird.

Yes, twisting a phone could certainly cause problems. I'd stop doing that immediately.

If you believe you have a hardware problem with your phone, make an appointment at the Genius Bar at your local Apple Store.

Just an update.

The wife and I had both used the ipad charger on occasion, the genius bar had no information on that topic.

They did however replace my wife's phone because she showed no software issues, mine however showed a bunch of system apps crash continuously so the rep actually blamed the problems on the screen being overly sensitive. I argued I wouldn't even have a hand near the phone when it would open other apps and dial numbers but they didn't really listen, they replaced my screen instead of the phone. I suspect it will keep happening and I will have to go back for a replacement.

I am still thinking the extra amperage from the ipad charger is frying these devices.

I agree that is probably to do with overcharging. Because for me it only arises after it reaches full charge and remains plugged in to the charger. But only seen with one charger - a charger that is genuine Apple Charger.

No, that is certainly not the case. Apple sells one charger for both devices in the online store, something it's unlikely that they would do if that charger "fried" iPhones.  The phone will not take anymore charge than it can use.

It's funny that so many people think everyone has a "local" Apple Store.  :-)

I have to drive 2.5 hours one way just to get to the closest one.

Apple also does service by mail. If you purchased a phone from a carrier, they may also provide assistance.

Unless you are an electrical engineer I do not think you are qualified to make that statement, or your an apple representative, either way I would hope you would back up that statement with some facts before telling everyone to keep using a charger that may in fact be causing problems.

Chargers:

When it comes to electrical damage, it is the amperage that causes the damage, and in this case the amperage of the ipad charger is more than twice the recommended for an iphone. Unless there is a capacitor between the phone and batter acting as a surge protector, which there is not based on all the information I can seem to find, then there is a strong change of excessive amperage getting through to the electrical components of the phone. Beyond facts, I will make on assumption that this may be exacerbated when the batter is fully charged and thus less able to absorb the extra amperage.

The only solid explanation that I have read here is that apples chargers are not really charges because that is regulated inside the phone, and the charger is simply a power supply that does not 'force' any amperage, or watts into the battery, nor the device. If this is true the next question that needs to be asked is if the internal regulator of the phone may be malfunctioning and 'allowing' improper current from the "power supply"? I feel like this is a likely scenario, as it is only affecting a small percentage of users.

If you are going to disagree and put everyone's devices at risk, state some facts please.

As far as apple goes, its not necessarily their fault, ignorance and lack of knowledge of a problem is not the company saying it is ok to keep using the charger.

This is the charge that Apple sells:

Check the "Compatibility" tab.

Yes, that is exactly how it works. Sometimes the problem is the charger, sometimes the phone itself.

And, no, I'm not an engineer. However, one of the regulars here, Lawrence Finch, is. He has repeatedly stated that using an iPad charger is fine (any misstatements are mine and not Lawrence's). Based on that and my personal experience using nothing but iPad chargers for my iPhones since there were iPads, I'm quite willing to recommend that using an iPad charger is fine.

Best of luck.
