IPhone ios7 restoring? (Security pass)?

Hey guys so i'm buying a used iPhone 4s with iOS7, i'm just wondering if you need the previous APPLE ID after you restore it on PC? Or you just need to put your own APPLE ID? (i already have one)
i'm talking about the new SECURITY PASS of iOS7 before you can use it.

APPLE iPhone 4S, ios 7.1 update, battery issues?

Last night my daughter installed the ios 7.1 update on her iPhone 4S. Prior to that, it worked just fine, or as normal as other iPhone 4S's batteries go. But this morning we noticed the battery was at 12%. When she put it on the charger before bed, it was sitting at 87%. It's a new charger cord & plug that has also worked just fine, in a wall outlet that works fine as well. Does the new ios 7.1 have some kind of battery draining issue for 4S? Any ideas out there?
