My phone will not stop crashing!
My iphone 3gs will not stop crashing about 10 seconds after I restart the phone. Is this a battery issue?
natalie, given the age of the phone, it is entirely possible that your issues are related to a bad battery. Use this guide to replace the battery and make sure that you get the right battery when you replace it. This model iPhone is finicky about its battery and does weird things when the battery fails. If nothing else, it will provide you with a known-good starting point for any further trouble shooting. Hope this helps, good luck.
I would try and replace the battery, but this is most likely a logic board issue because of the age of this device. In my honest opinion I would upgrade.
