I have an Iphone 6 (64gb Black) and I'm having serious problems with the battery life, I've been advised to Reset Network Settings & also backup and restore the phone to hopefully get rid of any faults and nothing seems to be working. My WhatsApp seems to be using the most battery at the moment, I know it hasn't update to support Iphone 6 / 6 Plus resolution yet so wanted to see if anyone else is having battery life problems with their new Phones from Apple!
