app killing battery

[YamahaJ93]

my iphone 5 has been dieing pretty fast lately, ive been only getting close to 4 hours of usage and a week ago i was getting 7 hours of usage and getting through a whole day without charging. i looked at battery doctor and checked what apps were using the most and it says in the power usage section that sunTrust mobile is using almost 18 mah of battery? i dont have an app like that ..any help would be appreciated thanks

What has changed since a week ago? What new apps have you installed, etc?
