Can I over charge my iPhone 4s?

Is it possible

No, the charger is designed to go to a lower power charge state when the battery reaches full. However, although you may not "overcharge" the battery, it is not good for the battery to be left charging for extended periods of time once it is full.

Hi

please don't over charge your iphone, it very harmful for your battery

My iphone I always plug in all night while I sleep… Battery is still great and have had no issues.

  • Why is my iPhone copying the same video over and over? So I took a screen recording earlier today and when I went to send it, there were about 50 of the same video. I thought alright i'll just delete them. So I did. And they returned. I now have over 300 of the same video and it keeps copying itself.
  • Why does Netflix keep pausing and playing over and over? I'm using it on my iphone 4. And I have checked my connections over and over I've uninstalled reinstalled, signed in signed back and everything else that the troubleshoot website has recommend. And it's gotten annoying. It didn't start doing this as much until I updated the app before the ios 7 release. I'm currently using the trial for netflix and my laptop doesn't work so I can get it on anything but my phone.
  • My iphone rebooting over and over? My iphne has been reboting itself. Its on for a few minutes but it just boots it self again. I tried every method but non of them work. I need the method for iphone 3g ios 6
  • My iPhone 4S keeps vibrating over and over for no reason? It does it like every 10 minutes for about 30 seconds. It's almost like getting a notification every second. I'm not getting any notifications though, it's just vibrating for no reason whatsoever… What's wrong with it?
