Okay, I'm not taking credit for this because I read this on one of the threads last night. Someone had mentioned to turn off the inbuilt iOS Facebook account in Settings. I did this last night and charged the phone all night long. Took it off the charger and used it for 15 minutes. Happy to report that in the 15 minutes of use the battery did not drop by a single percentage point.
I will continue testing this all day today and report back. If anyone else is willing to try please give it a shot.

I'll try this! Yesterday I had 5% left with 4.5 hours of usage and 10 hours standby. Only apps I was using were tweetbot, facebook, instagram.
