I don't know if it has already been posted here or somewhere else, but here it goes. I've read several articles praising the battery lives of both the iPhone 5 and the Galaxy S4, as they both would be superior than their predecessors. Most reviews appoint the iPhone 5 and the Galaxy S4 as having similar battery lives for Internet browsing. There seem to be differences, but not huge. However, I found a single article (http://www.stableytimes.com/news/five-apple-iphone-5-over-the-samsung-galaxy-s4/1111/) stating that these tests were done using 3G and not LTE. Under LTE, the iPhone 5 would have a much better battery life than the Galaxy S4 because the Apple gadget would have a more modern and advanced chipset than the Samsung device. Here's the paragraph I'm referring to: It sounds very strange to me, as I've not found another source on that. And the argument doesn't seem technical. Is there any truth to this? Would there be a great difference in battery life between the S4 and the iPhone 5 in LTE networks?
