    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 Inc.

    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.

    “The only waterproof large-screen smartphone“

    Xperia Z Ultra - The only waterproof large-screen smartphone
    • With IP55 and IP58 ratings the Sony Xperia Z Ultra is the only waterproof large-screen Full HD smartphone (display >5.5 inches, 1920x1080p) on global distribution.
    • There are 2 Fujitsu smartphones which are also considered waterproof, however these are specific network variants only available in Japan at the current time.
    • Strategy Analytics interprets water resistance to relate to the Ingress Protection Rating, or IP coding. The Xperia Z Ultra has a waterproof rating of IPX5/8, meaning it is waterproof at a depth of 1.5 m in fresh water and is jet resistant.

    As of 24 June 2013, outside of Japan, the Xperia Z Ultra is the only waterproof (IPX5/8) smartphone with a Full HD display on global distribution. This claim was verified by Strategy Analytics Ltd on 24 June and is correct. Source:

    experience filming underwater in Full HD

    Xperia Z Ultra has been built and tested to be compliant with IP55 and IP58. IPx8 and IPx5 provide the highest levels of protection against liquid ingress (also known as water resistance) according to the IP certification. A smartphone certified IPx5 and IPx8 qualifies as waterproof within these classifications. Read below for more details about the IP rating and test results for Xperia Z Ultra and its compliance with IP55 and IP58.

    **In compliance with IP55 and IP58, Xperia™ Z Ultra is protected against the ingress of dust and is waterproof. Provided that all ports and covers are firmly closed, the phone is (i) protected against low pressure jets of water from all practicable directions in compliance with IP 55; and/or (ii) can be kept under 1.50 metres of freshwater for up to 30 minutes in compliance with IP58. The phone is not designed to float or work submerged underwater outside the IP55 or IP58 classification range that may lead to your warranty will being void.

    Xperia Z Ultra has received IP certification ratings of IP5x and IPx5, IPx8. This means that this device is dust resistant, protected against low pressure water streams and it’s also protected against the effects of submersion in fresh water for 30 minutes up to 1.50 meter deep. Because Xperia Z Ultra is IP55 and IP58 compliant, it is possible to use the device in dusty environments. It is also possible to use the device when your fingers are wet, in extreme weather conditions (for example when it’s snowing or raining, or when humidity levels are high) or underwater (using the camera button to take pictures or film in regular swimming pool conditions, i.e. no salt water / sea ). See the table below for more details.

    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.

    IP certification, tests & results for Xperia Z Ultra

    Xperia Z Ultra has been assessed by an independent company to confirm its compliance to IP certification. The smartphone has been tested in an external test house, immersed in freshwater at a depth of 1.5m during 30 minutes and then removed from there. The basic functions have been checked and everything was working fine. Below you will find the details of the official IP certification report.
