4G LTE chipsets are undergoing the same power consumption refinements that all previous generation radio modem chipsets have had to go through. 3G UMTS was once just as bad as 4G LTE was earlier this year. Back around 2004 I remember a Vodaphone manager complaining about how hot the UMTS network test phones got in operation.
Since iPhone 5 uses Qualcomm's latest radio baseband modem, it gets the benefit of the current lowest power consumption radio chipset for LTE compared to the 3 year old phone in your comparison.
