iOS 6.1 Jailbreak iPhone 5 & Long Battery Life

I upgraded to iOS 6.1 a few hours ago and I must say that my iPhone 5 is getting insane battery life. I have been using my iPhone for almost 11 minutes (3G), standy for 2 hours and the iPhone is still at 98% ..

This is just crazy. My first day of running my iPhone 5 with iOS 6.1: Got 28 hours of standby and over 9 hours of usage. This is much better battery life then I received before iOS 6.1.

P.S. iPhone 5 is jailbroken with Evasi0n Jailbreak.

What is everyone else seeing?
