Interesting... I got a replacement phone from AT&T - unfortunately it already came with 1308 firmware. I restored all my apps, set it up as previous phone, did a full charge (using wired charger). Then I played with few apps (I don't have many - much less than you do) - checked Twitter/FB, played with WPCentral app (amazing app, b.t.w!), browsed a few sites/forums, adjusted some phone settings - my battery went from 100% to 87% in about 30 minutes! I didn't watch any videos or play any games... The only "background tasks" I had enabled were for "battery sense", "CNN" and "amazing weather"... The LTE is enabled for me and I cannot disable it with latest firmware. Now I have to guess if I got a defective replacement or if it is a fault of latest buggy firmware...
Edit: here's the screenshot... Pretty ridiculous for a smartphone (any smartphone) to have this drain with light usage:
