hi

And sorry if this is a repost but I searched and didnt see anything.

My Iphone 3GS has been shutting down lately at about 60-70% battery. Usually its when im doing something either using an app or finished making a call.

Sometimes i can turn it back on ..but sometimes I can not and the dead battery sign shows up.

After charging it for 2 seconds it comes back and at 60-70% battery where it was.

Apple says its something in the software, I flushed my phone and no help there.

IS there anything else it could be? maybe something with the computer I use to update it or sync apps?

Im at a loss...any help would be great.

Thanks.
