IPhone 3GS Keeps Restarting?

My iPhone 3GS suffered water damage about a year ago, and the only thing it effected was the LCD light (it's permanently dim, but if held in the right light, I can see it fine.) Starting about four days ago, it decided to randomly turn off and on, even when charging. I can use it fine in between, but every five minutes it just shuts down and turns back on. When I plug it in, instead of making the normal ding, it sounds awkward and mechanic, like it went flat. I know the obvious answer is to get a new phone, but I'm broke. Any other ideas? It's all backed up to iCloud, so should I restore it?

Try this:
Turn it off
Hold home button and power button at the same time
Than release power button but keep holding home, wait till it restart and apple logo come up.
If it's not working, connect it to a laptop and restore in iTunes

I recommend that you should restore it, it will definitely solve your problem

  • My iPhone 4S keeps restarting itself? Earlier on today, my phone died at 40%, when I switched it back on whilst charging it (took around 20 minutes) it was on 6% and then died, I charge it again and it was really low. I left it for a while and it went to 60% and mysteriously to 53%. Now it keeps restarting, I've tried doing the hard reset (holding the power and home button) but I've had no luck. Why is my phone doing this and how can I solve the problem?
  • My iphone 4s keeps restarting? - 2 My iphone 4s has been restarting every 1-2 minutes and won't hold charge very well, it will be on 100 then 2 minutes later it will be on 65. Ill be doing something on it like snapchat and it will freeze (the screen goes darker and all weird looking) then it will go black then the apple sign with come up and then it will go to the lockscreen. This happens all the time, when i'm charging it it will just constantly do this.
  • My iPhone 3GS keeps restarting automatically? My iPhone 3GS keeps restarting it is not turning on without a charger when I charge it it keeps turning off and on in seconds then it goes back on then off all my apps are moved. But I don't really want to remove all my data and all that as a new iPhone. When I remove it from charger its not even turning on.
