iPhone 6 and sets the smartphone bar

Good one:

   The iPhone 6 delivers a spacious, crisp 4.7-inch screen, improved wireless speeds, better camera autofocus, and bumped-up storage capacities to 128GB at the top end. iOS remains a top-notch mobile operating system with an excellent app selection, and Apple Pay is a smooth, secure payment system.

Bad one:

    Battery life isn't much better than last year's iPhone 5S. An even larger screen could have been squeezed into the same housing.

The Bottom Line:

     The iPhone 6 is an exceptional phone in nearly every way except its average battery life: it's thin and fast with a spacious screen and the smoothest payment system we've seen. It's the best overall phone of 2014.

    For years, Android phones have shipped with displays in expansive, 5-inch-ish sizes, but Apple had insisted on the necessity of a small screen for one-handed operation. The iPhone 5S, while powerful, hit a wall in viewing room: its 4-inch screen was among the smallest on the market, and, frankly, I found it limiting.

    Apple now has two larger iPhones: one big, the other even bigger. The iPhone 6 sports a 4.7-inch screen, while the iPhone 6 Plus goes full "phablet" with a 5.5-inch display. Compared to earlier iPhones, both of the new models boast thinner bodies, ship with faster A8 processors, slightly improved cameras, speedier Wi-Fi and LTE cellular data, better voice quality if you're using voice-over-LTE, and -- except in the entry-level models -- more onboard storage. And like all current iPhones, these are running  it's a far less revolutionary update than ios 7 was, but it adds some nice improvements and customization options, including notification widgets, replaceable keyboards, a new health app and apple pay.

For iPhone 5S owners or habitual iPhone upgraders,

    Think of its chief advantages as a bigger screen and the potential of Apple Pay. The improved processor, camera, 4G LTE and Wi-Fi speeds, and possible battery-life gains are steps up, but not massive leaps. In other words, if you don't have a strong desire for the larger screen, you could easily ride your iPhone 5S (running iOS 8) for 12 more months, and wait for the inevitable iPhone 6S and 6S Plus in 2015.

For hard-core Android fans, 

   well, there are Android phones that cost less, have higher-resolution screens (and screens even larger than the 6 Plus), boast better battery life, have removable SD card storage, and even removable batteries. And the Android camp has an all-new operating system, too, with andriod lalipop. You won't find any of these on an iPhone 6; you can't have everything in Apple-land. That said, the larger screens of the new iPhones combined with iOS 8's bevy of familiar customization features make the 6/6 Plus the most attractive iPhone generation yet, and the most tempting to Android owners in years.
