If you compare the Galaxy S3 and the Galaxy S7 with the Samsung Galaxy S6 duo, it’ll be pretty obvious that the Galaxy S6 duo did badly in comparison, especially the Edge variant.

Although they received quite a lot of hype, the flagship devices ranked in tenth on the best-selling smartphone list by the end of their debut sales quarter.

Even after almost a year in the market, the Galaxy S6 and its Edge variant only managed to secure 7 percent of the total Samsung U.S user base.

There are many reasons that led to these devices failure such as its poor software support to the not-so practical curved display design.

However, what could be the main reason behind this failure? Some people would say its the lack of an microSD slot while others say it’s the pricing of the S6 Edge. But, the people from Kantar may have discovered the underlying issue.

A recent poll conducted by Kantar among Galaxy S7 and S7 Edge users show that 53.2 percent had opted for these devices due to its battery life. The second reason was the camera, with 50.9 percent votes.

Having said that, only 39.8 percent an 36.5 percent of respondents have picked performance and storage capacity, suggesting that a microSD isn’t as important as a bigger battery.

Samsung Galaxy S6 and the S6 Edge is fitted with 2,550mAh and 2,600mAh, respectively, whereas the Galaxy S7 comes with a 3,000mAh battery and its Edge variant boasts 3,600mAh battery.
