There were a few times when colors on the Nexus 4 had warmer tones and less contrast, but these instances happened so rarely that it's difficult to make a call between the two.

For those who care about such things, the iPhone 5's material quality trumps the Z10's treated plastics and loose back panel that too easily pops out when I slide a nail anywhere along its perimeter.

It actually adjusts brightness while you're using the device, not just when you first turn on the screen (as is the case for the iPhone 5, and Nexus 4).

It's fairly large though at 2,100mAh and does a serviceable, if unremarkable job of keeping the Nexus 4 running - you'll probably still need to charge it every day though.

This is the part that BlackBerry users aren’t going to like; battery life on the Z10 isn’t anywhere close to what you’d get on your BB7 or earlier hardware, which is likely the price BlackBerry had to pay to get everything up to snuff with the competition.

Left untouched, the smartphone seems to sip battery, but once you start using it for any length of time, it gets quite warm (warmer than my iPhone 5 or Nexus 4 by a long shot) and mows down battery quickly.

The new BlackBerry Browser will be a welcome upgrade to any existing BlackBerry owner in particular, but although the browser performs well, it still doesn’t render nearly as fast or as well as my iPhone or Nexus 4.

In my testing, I found that playing locally stored video on a constant loop, while connected to a cellular network and running a few apps in the background, the Z10 managed an impressive 9 hours of battery life, and while doing a browser test that performed a loop of random Google image searches on Wi-Fi (made more difficult by the fact that I couldn’t turn off screen lock), it managed 5 hours and 45 minutes.

I did notice, though, that with both handsets set to maximum brightness, the iPhone 5 outshone the Z10, and an HD picture of a flower looked brighter, more detailed, and had more color variation on Apple's device.
