Following an upgrade to IOS 5, my iPhone (3GS) keeps turning itself off.
Following an upgrade to IOS 5, my iPhone (3GS) keeps turning itself off. After power up the phone will remain on for no longer than 10 minutes before shutting down and re-booting itself.
I note that some users are experiencing problems with their battery after the upgrade but the problem I ma experiencing occurs even when the phone charging.
Any ideas on the cause or how to fix this? Thank you.
iPhone 3GS, iOS 5
