Why does a message on my iPhone keep popping up that that This accessory may not be supported?

Why does a message on my iPhone keep popping up that that "This accessory may not be supported"?

Added (1). I'm charging it if that makes a difference but I'm using the charger that came with the phone.

It says this because the accessories aren't "supported" with your phone meaning it wouldn't be a wise choice to use that accessory with your phone because it was made cheap. Say you got a $3.00 or less charger from amazon, those cheap chargers can overheat at night and cause fires and that's probably true with the stuff that says "this accessory may not be supported". This is where i get all my electronic accessories. They are very cheap and very good products. Www.monoprice.com.

But I'm using the charger that came with the phone.

  • Why does this message keep popping up? I started using my other iPhone because the one I had got stolen but this is the iPhone that I downloaded IOS 9 beta on so every time I turn on my phone, this message that says to update to IOS 9.1 from beta keeps popping up. So I checked the software update place to update but it says IIm up to date? I would just ignore it but now it's starting to get annoying. Please help, how do I get rid of it or update to iOS 9.1?
  • Why does my iphone shows that charging is not supported with this accessory? I think I had my phone plugged in to my laptop for more than 2 hours and it hasn't charged fully. It's like 32 percent charged since I plugge it in. And now it says the above question. I don't know why?
  • Why does my iPhone say my charger is not supported with this accessory? If tried canned air changing my charger check for iOS updates but know change I'm starting to think my my charger is not compatible with the iPhone 3GS
  • Why does my iPhone 3 say 'Charging not supported with this accessory'? So recently my ipod got stolen, and my friend decided to give me her old iphone 3 to use instead. I used my old ipod charger with it, and it worked but then i updated the software to iOS 6.1.6 and it wouldn't charge in an outlet anymore, it is only able to charge when i connect it to my computer. I already searched online about this and someone said to put the phone onto airplane mode then charge it in an outlet but that didn't work. Any suggestions?
