iPhone 4S, clean install, so I don't think reseting the network settings will improve something for me.
I previously used the app named Carat to evaluate my battery life, on iOS 7.1.2 I had a battery life of approximately 7-8 hours and a J-Score of 70-80 (i.e. my battery life was better than 70-80% of iPhones using Carat) and now on iOS 8 I barely have a battery life of 4 hours and my J-Score dropped to 20...
Tweebot seems to use way more battery compared to iOS 7 and is the major offender in iOS 8, maybe it is just not optimized for iOS 8 right now.
my tweetbot hardly uses any battery..always among the lowest on the battery usage list
