EDIT: Mods, feel free to collapse this to the current massive Nexus 4 thread later on, if you wish. According to Reddit, these are, yet unpublished, new benchmarks from Anandtech with new (but final?) Nexus 4 software. Not even sure what the benchmarks actually mean, but they fare much better http://www.reddit.com/r/Android/comments/12rk7s/anandtech_have_run_new_nexus_4_benchmarks_which/ Here's the GLBenchmark post by Anandtech: http://www.glbenchmark.com/resultsoflogin.jsp?login=anandtech&benchmark=glpro25 ---------- And here's GSMArena's final battery test for the LG Optimus G: I see where they get the 15.3 hour talk time from for the Nexus 4 now. Regarding the browser time, that's using LTE, I'm assuming. So without LTE, you lose some speed, but will gain battery longevity.
