When someone doesn’t want something as large as a tablet or as small as a smartphone, they usually go for a “phablet,” a middle-of-the-road device that provides both convenience and moderate size so that they get the best of both worlds. It sounds weird, but, in fact, the device has picked up quite a bit in sales over the last year.

eMarketer reports that, from sales numbers provided by Flurry, global mobile app sessions for “phablet” devices have managed to increase nearly 150 percent from the previous year’s usage for January. Meanwhile, the growth of the mobile industry as a whole was only at 78 percent — nearly half that number.

Devices like the iPhone 6 Plus and Samsung Galaxy Note 4 provide larger sizes, but also convenience with usage. These two led that charge of popularity, while medium-based smartphones only showed a 38 percent increase, and small tablets followed way behind with 14 percent. Meanwhile, full size tablets and smaller phone models decreased, by 20 and 16 percent, respectively.

In addition to the popularity of mobile apps, mobile websites are also generating big audience numbers on “phablets.” Research company Chitika reported that the percentage of website traffic for North America coming from bigger smartphones (with a 5-plus inch screen) picked up around 160 percent between September 2013 and September 2014 — almost the same amount of growth as the numbers reported above.

The average size of a screen on a “phablet” has seen an increase on newer models. Previously, phablet screens clocked in at around 4.6 inches back in 2013. Currently, however, the popular norm is around 5.1 inches, and it’s likely it could grow even a bit more in 2015 with new models that are introduced (probably not to the point of tablet sizes, though).
