8. iPhone 6 Plus
Sales Percentage: 1.7%
Although iPhone is currently the second best selling smartphone in the US, 6 Plus couldn’t particularly make an impact on the market. Despite the initial hype about the bigger size, the phone wasn’t able to generate a lot of sales for Apple. It is believed that the lower sales were a result of the hardware defect controversy (the bending problem). However, it is still the 8th best selling smartphone phone in the US. IPhone 6 Plus comes with a 5.5-inch screen and 8MP rear camera.
