These days, a phone isn't worth having if it doesn't have a top-notch snapper strapped to its back.

We've rounded up the crème de la crème of camera phones and delved a little deeper than simple megapixels to establish what handsets should be on any self-respecting mo-pho's (mobile photographer's) wishlist.

It seems raw power has been replaced with more nuanced designs of late, so we've selected what we think are the best cameraphones on the market at the moment and pitted them against one another.

However, rest assured we'll be adding to the test as more top-end phone snappers appear to ensure you're always aware of which phones are the best around for photography.

The TechRadar photo team has spent weeks with each device, taking photos in a variety of conditions and subjecting them to the same tests as the high-spec cameras we review every week to give you a real feel for the raw pictorial power of each phone.

However, we also look at how easy each phone is to use on a day by day basis - there's no point bringing a photographical powerhouse on a hike if it's impossible to use the blasted thing.

Where possible we shot specially designed charts to test the cameraphones' image quality, including our resolution chart, which gives a measure of how much detail each camera can capture. This is assessed by eye on a computer screen and is measured in line width per picture height x100 (LW/PH). High numbers are good as they indicate that more detail can be recorded.

We also shot charts to enable us to use computer software to assess how much image noise each camera generates, their ability to record light and dark tones within a single image (dynamic range) and their colour accuracy.

See here for more information about our noise and dynamic range tests.

We used the cameras in a variety of different situations, both outdoors and indoors, using different camera settings (where possible) and in different lighting conditions.

The images were all then examined on a computer screen at normal viewing size and at 100%.

So read on to find out which phones come up trumps in our test, and which should stick to the day job of transmitting our voice and texts across the airwaves.
