Samsung Galaxy S4 LTE-A Battery Benchmarks Appear!
We've already seen how powerful the Qualcomm Snapdragon 800 chipset and processor is from benchmarks done with the Samsung Galaxy S4 LTE-A but it won't be very useful if it doesn't have good energy efficiency. Testing this out, it was recently put through some synthetic battery tests for 3D rendering, Video Playback and Browsing. According to the testers, the other Samsung Galaxy S4 version in the bunch is the Exynos 5 Octa powered I9500. From the benchmark results it shows that the Samsung Galaxy S4 LTE-A gets more or less the same performance with the Samsung Galaxy S4 I9500 in Browsing and Video Playback but beats the Samsung Galaxy S4 I9500 in 3D rendering (probably due to the better Adreno 330 GPU the Qualcomm Snapdragon 800 chipset has).

While we would have liked to see less synthetic tests and more thorough real-life battery tests, we'll just have to wait and see as these kinds of tests usually take much longer to do. It also shows that if the other Samsung Galaxy S4 in the testing really is the I9500 then the new Samsung Galaxy S4 LTE-A is less battery efficient than the Snapdragon 600 powered I9505. The reason we're a bit skeptical that the other S4 is the Exynos 5 Octa powered I9500 is because from other battery benchmark tests, the Samsung Galaxy S4 I9505 had much better real-life battery tests than the Samsung Galaxy S4 I9500. For now rest assured that you're getting a much better processor with just as good battery life, but do take these benchmarks with a pinch of salt as actual battery tests may change as smartphone firmware gets updated.
