Who hasn\u2019t dreamed of a phone that resists water? As summer approaches, with swimming, beaches and outdoor activities, <\/span>protecting your smartphone becomes a real necessity<\/b>. Even though several models are now advertised as waterproof, <\/span>that doesn\u2019t mean they can be submerged without consequences<\/b>. Water resistance is a useful protection, but it has its limits. It\u2019s therefore essential to understand how it works to avoid damaging your battery and internal components.<\/span><\/p>\n

The IP rating: an essential guide before you buy<\/strong><\/h2>\n

Before buying a smartphone marketed as \u201cwaterproof\u201d, you should know that there are <\/span>strict standards defining how well a device is protected against dust and liquids<\/b>. These standards are grouped under the <\/span>IP rating (Ingress Protection)<\/b>, made up of two digits. The first digit indicates the <\/span>level of protection against solid objects (dust, particles)<\/b>, while the second digit relates to <\/span>resistance to water or other liquids<\/b>.<\/span><\/p>\n

Understanding protection levels against solids<\/span><\/h3>\n
    \n
  • 0 or X<\/b>: No certified protection<\/span><\/li>\n
  • 1 to 4<\/b>: Increasingly fine protection against solid objects ranging from 50 mm to 1 mm<\/span><\/li>\n
  • 5<\/b>: <\/span>Partial protection against dust<\/b><\/li>\n
  • 6<\/b>: <\/span>Full protection against dust<\/b><\/li>\n<\/ul>\n

    Understanding protection levels against liquids<\/span><\/h3>\n
      \n
    • 0 or X<\/b>: No protection<\/span><\/li>\n
    • 1 to 3<\/b>: Basic protection against falling water droplets<\/span><\/li>\n
    • 4<\/b>: <\/span>Resistance to splashes and water spray<\/b><\/li>\n
    • 5 to 6<\/b>: Able to withstand increasingly powerful water jets<\/span><\/li>\n
    • 7<\/b>: <\/span>Can withstand immersion up to 1 metre for a maximum of 30 minutes<\/b><\/li>\n
    • 8<\/b>: <\/span>Can be immersed deeper than 1 metre, for 30 minutes<\/b><\/li>\n
    • 9\/9K<\/b>: Resistant to <\/span>high-pressure, high-temperature washing<\/b><\/li>\n<\/ul>\n

      So, for temporary and controlled immersion, <\/span>only smartphones with an IP rating starting with 7 or 8<\/b> (such as <\/span>IP67, IP68<\/b>) are truly suitable. It\u2019s therefore crucial to <\/span>check this rating before you buy<\/b>, especially if you\u2019re often around water.<\/span><\/p>\n

      Protection against water\u2026 but not without precautions<\/strong><\/h2>\n

      Even if a smartphone is certified IP67 or IP68, <\/span>that doesn\u2019t mean you can dive with it without a second thought<\/b>. These ratings guarantee resistance, not long-term use in water. <\/span>An IP67 rating protects against immersion of less than 1 metre for 30 minutes<\/b>, while IP68 can go <\/span>down to 3 metres<\/b>, still for a limited time.<\/span><\/p>\n

      Occasional use only<\/span><\/h3>\n

      Despite a high rating, <\/span>manufacturers themselves advise against frequent underwater use<\/b>. In reality, these protections are mainly designed <\/span>for unexpected accidents<\/b>, such as dropping your phone in water, not for filming your diving sessions.<\/span><\/p>\n

      Once opened, a phone is no longer truly waterproof<\/span><\/h3>\n

      Another important point: if you\u2019ve <\/span>opened your smartphone for a repair<\/b>, or this has been done in a workshop, <\/span>the original water resistance may no longer be guaranteed<\/b>. This is because <\/span>a specific seal protects the internal components<\/b>. Once this seal has been moved or poorly refitted, water can seep in, <\/span>causing irreversible damage<\/b>, particularly to the battery, motherboard or connectors.<\/span><\/p>\n

      The right habits to avoid damaging your device<\/strong><\/h2>\n

      A smartphone with an IP rating should not be treated as a fully submersible device. To avoid serious damage:<\/span><\/p>\n

        \n
      • Never deliberately submerge your phone<\/b>, even with an IP68 rating<\/span><\/li>\n
      • Avoid any prolonged contact with water<\/b>, especially if the device has already been opened<\/span><\/li>\n
      • Choose equipment specifically designed for underwater filming<\/b>, such as waterproof action cameras<\/span><\/li>\n<\/ul>\n

        A waterproof phone is above all <\/span>a safety net in case of a one-off accident<\/b>, not a tool designed for water sports and activities.<\/span><\/p>\n

        Conclusion: water resistance doesn\u2019t mean invincible<\/strong><\/h2>\n

        Owning a waterproof smartphone is a real advantage, especially in summer when we spend more time outdoors. However, <\/span>this water resistance is regulated, limited, and can be compromised by poor handling<\/b>. To protect your battery and components, adopt <\/span>sensible use around water<\/b> and <\/span>don\u2019t replace your waterproof camera with your phone<\/b>, no matter how tough it claims to be.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
