My I phone 4s is 8 weeks old. I did the os update a few days ago and today when i went to use my phone it said it was low on charge. I tried plugging it in to the computer no help. I used my wifes cord from her I phone and still no good. My wifes phone charges on both cables and she also did the os update at the same time. I called verizon an after some trouble shooting with them they passed me over to a different tech support. They told me that about 2 out of every 10 I phones get this problem and they will have to send me a new one in the mail. Wow 20 pct of the I phones have this issue. So now i'm assuming that I'm not going to be able to get my contacts or pictures out of this phone. I'm just wondering if it was caused by the os that I upgraded too but all the post i see on line are of the battery draining faster than before havn't found a post about this issue
You can call Verizon to replace it or go to an applestore to replace it since it won't even power on with multiple chargers.
