Earlier quoted context omitted.
The Nexus 4 and the iPhone 5 have similar battery life if you disable LTE on the iPhone. The faster you can finish loading your data, the sooner you can turn off the LTE chip and start saving power again.
Well this is just rubbish. http://www.anandtech.com/show/6440/google-nexus-4-review/2 The iPhone 5 has nearly DOUBLE the battery life of the Nexus 4 for typical usage. If you disable LTE it will be even better.
> "As always we test across multiple air interfaces (3G, 4G LTE, WiFi), but due to the increased network load we actually find that on a given process technology we see an increase in battery life on faster network connections. The why is quite simple to understand: the faster a page is able to fully render, the quicker all components can drive down to their idle power states."
AnandTech's 3G benchmark scores for the iPhone 5 and Nexus 4 are 4.55 and 4.15, respectively. It's only when the iPhone 5 runs on 4G LTE that it scores 8.19.
And while I appreciate AnandTech's quantitative reports, I'm not sure you can call this "typical usage", unless you typically spend all day refreshing web pages.
