A YouTube Channel that goes by the name of PhoneBuff did a review between the Samsung Galaxy S7 that is packed with Qualcomm's Snapdragon 820 chipset and the other version that is packed with the Exynos 8890 chipset. Given that he lives in the U.S., he had many interesting things to say about the two devices, especially the U.S. version.
The Software Performance
The U.S. version carries Qualcomm's Snapdragon 820 chipset, while the global version is packed with Exynos 8890 chip - a chip that is personally made by Samsung. Now, how do the two Galaxy S7 smartphones differ from software performance?
The U.S. version is not only slower in initially loading up applications, but is also in keeping those applications ready for the user to use in the background. Essentially, this means that the variant packed with the Snapdragon 820 chip is slower in terms of performance.
Now, you could say that Samsung has to worry about using two different chips. And given that they personally created the Exynos 8890 chip, Samsung will be without a doubt, be more familiar with it and give it more attention. However, that doesn't seem to be the case.
According to the video source, Samsung is the exclusive manufacturing partner for Qualcomm in creating the Snapdragon 820 chip. Samsung was also the company that won the contract that some analyst say was worth a billion dollars to make the SD 820 chip. So basically, they should be familiar with it, given the position that they were in.
The Battery Life
The U.S. version of the Samsung Galaxy S7 also has a weaker battery life compared to the global version. According to reports, the global version (Exynos-based) Galaxy S7 is, on average, had a battery life of over 71 percent more efficient compared to its twin.
Again, you may say that it has to do with the chip. But the video source compared the U.S. version to another Android smartphone that features the same battery capacity (3,000 mAh) and the same chipset in which the Galaxy S7 performed lower compared to the HTC 10. And according to the video source, this is not caused by the processor or battery, but rather the optimization of the U.S. version of the Galaxy S7.
Other Miscellaneous Things
For this part, these may not seem to be a big deal for most people, but these are the small differences that you can't help but notice once you experienced both devices.
First is the packaging box. For the global version, it has this classy magnetic clasp that closes the back elegantly. As for the U.S. version, that classy magnetic clasp is nowhere to be found. Instead, buyers in the U.S. have this little paper tab instead.
Second is the logo. On the back design of the global version, there is no logo stamp of Samsung. But for the U.S. version, it has.
Third, is carrier bloatware. When you open the U.S. version of the Galaxy S7, it shows you a bunch of carrier apps. Yes, you can disable them, but they won't be completely gone inside your phone's memory. They will always be there lurking around and taking up precious storage space.
