Galaxy S5 LTE-A: Battery Life, Performance
 

While I was planning on doing a full review for the GS5 LTE-A, it turns out that there’s relatively little that changes between the original Galaxy S5 and this Snapdragon 805 version. For those that aren’t quite familiar with this variant of the Galaxy S5, most of the device stays the same in terms of design, battery size, waterproofing, UI, and camera. What does change are the SoC, modem, and display. The SoC is largely similar to the one we see in the original Galaxy S5, but a minor update to CPU (Krait 450 vs Krait 400), more memory bandwidth, faster GPU, and faster ISP. In addition, the modem goes from category 4 LTE support on a 28HPm process to category 6 LTE support on TSMC’s 20nm SoC process. What this means is that the maximum data rate goes from 150 Mbps to 300 Mbps. Finally, the display goes from 1080p to 1440p in resolution, and we've previously covered the display's surprisingly good calibration and general characteristics.
