Claims and Test Results

The claims on these pages are mainly based on results from tests conducted by Strategy Analytics, an independent global company specialising in market analysis. In some cases, tests were also conducted in laboratories at Sony Mobile Communications AB

All claims were verified at the time of testing. However, as the mobile landscape changes quickly and new phone models are released on a continuous basis, we cannot guarantee that all claims are still valid as you read this. Please see the date specified at the bottom of each claim and test specification for reference.

Xperia Z1 gives you the best overall image quality of all leading smartphones

The above claim was found to be supported based on a blind assessment of images captured by Sony Xperia Z1 and Apple iPhone 5, HTC One, Nokia Lumia 1020, Nokia Lumia 925 and Samsung Galaxy S4 and rated by 206 UK consumers. Research was conducted by Strategy Analytics between 12th – 15th August 2013.

Methodology – Consumer assessment

Test methodology for Xperia Z1 camera scenario

Strategy Analytics’ researchers captured images taken by Xperia Z1 and 5 competitor devices in 5 different scenarios.
Competitor devices were: Apple iPhone 5, HTC One, Nokia 925, Nokia 1020 and Samsung GS4
These devices were determined by Strategy Analytics to represent the leading smartphones in terms of sales volume or flagship ‘imaging-centric’ smartphones.
Scenarios were:

  • - Baby asleep at ultra-low light
  • - Toy train speeding around a track
  • - People at a party (dusk, soft back-lighting)
  • - Building at twilight
  • - Close up of a lined face with bright backdrop

For all devices in all scenarios, flash was set to ‘off’ and all other device settings were configured as ‘out of the box’.

Test methodology for Xperia Z1 camera scenario

As many of the scenarios included moving elements, the two project researchers captured 3-5 images with each device and, having carefully reviewed each set, selected the shot which achieved the best focus and best framing of the subject for each device in each scenario.
- In the train scenario, the variable reaction times of the smartphone cameras meant that, in order to capture the train, the researcher was required to manually follow it through the viewfinder to ensure that the object was in frame when the shutter was pressed. While this manual intervention meant that the angles of capture were slightly different for some devices, this was determined to be the most suitable approach to achieve a fair comparison with the train in shot for all images. Participants were asked to ignore these differences in framing when judging the image quality. Additionally, researchers made every effort to minimise instability for all devices.

Over a period of four days (12-15 August 2013), 206 consumers assessed the quality of the images produced in each of the five scenarios, by each of the smartphones:
- Equal numbers of consumers evaluated the images created in three different formats: printed out on A4 glossy photo paper; on the displays of the device itself; and on a large screen (50”) HD monitor
- To eliminate bias, the devices were hidden from the consumers behind card (so that only the display was visible) and the images were only identified by letter (A, B, C, D etc.). The order of exposure was counterbalanced.
Participants were recruited to a profile established to reflect the UK adult smartphone buyer population. Data from Strategy Analytics’ previous independent consumer surveys was used to validate the demographic profile of this population.
The profile of the final sample was:
- 52% male; 48% female
- 35% aged 18-29 years; 37% aged 30-44 years; 28% aged 45+
- 89% currently own a smartphone; 11% intending to purchase a smartphone within 3 months

NB ‘Smartphone’ was defined as any product used as the participant’s primary mobile device that is powered by iOS, Android, Blackberry OS or Windows Phone

Consumer assessment of the Sony Xperia Z1
Consumer assessment image test protocol

Participants rated each image on a scale of 1 to 5, where 1 = very poor and 5 = very good, for four factors:
- Sharpness, Brightness, Life-likeness, and “Overall picture quality”
These factors were chosen as the basis of assessment because they were found to be the key factors that consumers use to judge image quality in an in-depth qualitative study on camera and imaging that was conducted by Strategy Analytics on behalf of Sony Mobile with 39 consumers in July 2013.

Overall findings

Average Rating for “Overall Image Quality” of Sony's Xperia Z1

On average, consumers rated all images captured by Sony Xperia Z1 as 3.7/5 for ‘overall image quality’.
- By comparison, all competitors were rated 3.0/5 on average or less.

Xperia Z1 consumer assessment: % who rated images 4 or 5 for “Overall Image Quality”

In 59% of cases, consumers rated images captured by Xperia Z1 as either “Good (4/5)” or “Very Good (5/5)”.
- By comparison, images captured by competitor devices were rated good or very good in 40% of cases or less.

Xperia Z1 consumer assessment: % of cases where image was preferred among competitive set

In 59% of cases (across the five image scenarios assessed) consumers preferred* the image captured by the Xperia Z1.

* “Preferred” means that the Xperia Z1 image received the highest rating (or joint highest rating) of the six images rated by an individual consumer for a specific scenario.

About IP (Ingress Protection) ratings

When a device receives an IP rating, it has undergone certification testing to measure its resistance levels to both dust and water. The first digit in the two-digit IP rating indicates the level of protection against solid objects, including dust. The second digit indicates how resistant the device is to water. The higher the numbers, the higher the resistance.
