The post I was responding to praised Google for ditching LTE buzztech in favor of (among other things) better battery life. Real world data shows that this isn't the case - the "buzztech" actually provides an enormous boost to battery life.
In this particular benchmark, it is very clear that LTE is the winner across the board. In 'real world usage', I have to disagree. I'm sure anyone with an LTE phone will tell you that disabling the LTE radio absolutely gives a boost in day-to-day battery life.
This has been my experience as well. I find that in every day use, especially in areas not saturated with strong LTE, it can become a battery suck.
I'm certain downloading a 200 mb PDF over LTE in Manhattan takes less power than downloading that PDF over HSDPA+, GSM, or GPRS. But in my experience with several devices, having LTE on all day in Fairfield County, finding it sometimes but often not, takes more power in so-called "standby".
