Android L : Battery Performance

I have been using N5 as my daily driver since its launch and I have always had complaints about its battery performance..So, I resorted to hibernating the apps, clearing the ram and all sorts of other battery improvement tricks. I have been using Android L since last two days and I have already seen a good battery performance on N5..following are my battery stats from last two days..and I can say that I can now use my n5 for a whole business day without any problems and without using any tricks/apps..what do you guys think? have you seen any battery performanceimprovement?

Google has already claimed that L will be battery efficient, so lets see how much juice it can provide
