For those who are deciding between HTC One and Samsung Galaxy S4; here's my comparison report after a couple of months usage of both handsets. I have the Sprint CDMA version for both, of-course on Reliance CDMA now The best thing about the HTC One is its look and feel. With all Samsung Galaxy handsets looking similar, S4 will look like it belongs on a far more downmarket phone. HTC One on the other hand stands out from the rest of the crowd and gets more attention as it doesn't have the common look like a Galaxy or even an iPhone. When I was at the Burj Khalifa (Dubai) in early May, a foreigner there saw the HTC One in my hands and screamed "hey look... its the new HTC handset!" - I don't think he would have noticed if I was using a Galaxy S4. The replaceable battery option does get some points for Galaxy S4 though. Since I had used a Galaxy S3 before, the S4's rectangular boxy shape did not feel that comfortable as the S3's under body cover is more curvy and hence more comfortable. Anyway the S4 is more comfortable to hold than the HTC One for me as it feels to have more grip. The Ones power button is on the top left edge, and doesnt really extend from the phones surface at all. So if you are upgrading from a handset like S3, it will take some time to get used to it and especially the navigation buttons. Even though the screen size difference is only 0.3", I do feel it makes a good difference as the HTC One screen looks a bit more cramped when you look at it many days after using the S4. So a big advantage there for the S4 over HTC One. Feature-wise Samsung Galaxy S4 has load of cool features but in the 2 months of usage I had, the only time I used those "cool" features were when I was showing off the handset to someone or when they asked me about those features. Yes, they do work fine and not just gimmicks, its just not really going to be used all the time. Those "cool" features do take up battery life as well. Camera had mixed results for me. Some pics looked better on HTC One while some looked better on S4. The HTC Ones colors are more accurate in my opinion and more crisper. Overall, I would say the HTC One is better for low-lit conditions. Battery life feels more or less the same with both handsets. BlinkFeed on the HTC One was kind of weird for me in the beginning but eventually I started liking it. Make sure you filter the sources that you require to make it better. I still like TouchWiz navigation than HTC Sense, maybe that has something to do with the fact that I was used to it before with the S3. I have seen many reporting over-heating problem with the GSM Galaxy S4 but I haven't noticed any over-heating issue with the Galaxy S4 CDMA (mine is Sprint). The most disappointing aspect of both HTC One CDMA and Galaxy is that SVDO (Simultaneous Voice and EV-DO) has been removed which was present in Samsung Galaxy S3 and HTC EVO 4G LTE. The reason behind it is that they added simultaneous voice support for LTE which is more popular now in US than EVDO. So the 3G (EVDO) data session will get cut off when you make or receive a call. EVDO works great on both handsets. I have run these tests on both handsets together at the same time... Galaxy S4: HTC One:
I have heard some people say that EVDO is faster on HTC handsets but in my opinion it just varies. I have done EVDO speed tests on both handsets together at the same time during different time of the day/night and have seen varying results. However I do notice that HTC One had more reception signal strength as per the dBm ratings checked together at the same time: (the dBM value is in -ve, so the lesser (to 0) the better)
