    My iPhone (4, 16gb) ran out of battery yesterday so i plugged it in to charge on the usb socket on my laptop, it turned on and charged, but then started flashing between the lock screen and the charge screen as if i was plugging and unplugging it, over time it came to be spending more time on lock screen than charge and began effectively draining itself by lighting up and making a noise every time a tiny bit of charge trickled in every few minutes. I tried plugging it in to the wall instead and got the same problem, then i got an error saying that the device i've connected is not optimised for iPhone (or words to that effect), this was even coming up when it wasn't plugged in, and also an error saying charging is not supported by this accessory, which all seems really strange seeing as the 'device/accessory' that doesn't support charging and isn't optimised for iPhone is an official Apple iPhone charger. I've tried blowing/gently brushing the connector on the cable and on the phone to no avail. The cable is fine as it charges an iPad, which I assume draws more current. I have no way of checking whether the cable works for transferring of data or not as the computer I have doesn't have Mac OS or Windows on it and I can't seem to get any decent 3rd party apps that work, thereforee any solutions along the lines of plug it in to your pc/mac and reinstall the OS are completely useless to me, i've had the 'charging not supported' error come up before but it was when the cable i was using was damaged, i'm really at a loss as to what it could be

    Have you tried doing a hard reset with it plugged in?
    Also does the computer recognize it at all?

    it's plugged in now, i've tried holding the 2 buttons down, i assume that's what you're referring to, as for if the computer recognizes it i don't know, i'm on a really old knackered pc with linux on it, i transfer files on and off my phone over wifi, other than it charging when i plug my pc in i have no other way of knowing whether its recognized it, it certainly hasn't mounted the image folder and tried to import photos or anything like it does on windows and when i run digital camera software it detects nothing, but having never took items on or off the phone in this manner before i don't know whether the camera software even detected it when it was working, also this computer is so old i'm pretty sure its on USB1 so it will probably not even work properly anyway, i guess times like this it would make more sense to have windows but its just painfully slow on this computer
