Technology sites, such as TechRadar and ZDNet, offer reviews and comparisons of what they consider to be the 10 best smartphones available. A number of smartphones, such as the iPhone 6 and Sony Xperia Z3, feature highly on both sites' lists.
ZDNet rates the iPhone 6 and iPhone 6 Plus as the best smartphone available, as of early 2015. While these devices are the most expensive smartphones available, they are an excellent choice for heavy smartphone users, especially those that need to have a powerful, precise camera, and the processing speed to handle business related apps and software.
TechRadar, on the other hand, gave the iPhone 6 a number two spot, instead opting for the Samsung Galaxy S6 as the best overall smartphone currently available, as of early 2015. The Samsung Galaxy S6 was rated highly in terms of screen size, overall audio and video quality, as well as excellent screen resolution at 1440p. This smartphone is expensive as a result, however, much like its iPhone counterpart.
The Samsung Galaxy Note 4 was rated in the top 10 by both sites — second place by ZDNet, seventh by TechRadar — because of its large, clear screen, impressive processing power and high quality camera. This is one of the most powerful Android phones available as of early 2015.
