For many years, phones with the label "IP68 waterproof, dustproof" have given users the feeling of security that the device can withstand sudden falls into water or showers.
However, Google has just officially admitted that this protection ability has gradually declined over time of use, putting users at the risk of damage that they often do not expect.
According to information on the latest support page, Google said that IP68 standard, which allows the phone to withstand water at a depth of 1.5 meters for 30 minutes, will not be a permanent guarantee.
Rubber gaskets, waterproof glue and other sealed measures will gradually wear down during daily use such as dropping, hitting, to contact with dirt.
That means that after a period of time, the water resistance that has been tested in ideal laboratory conditions will decrease significantly.
IP68 standard has long been a familiar number in smartphone advertising campaigns. But in reality, it only reflects the protective capabilities of the equipment when it was first launched.
Technology experts say that many people mistakenly think that waterproof labeling means absolute safety, while this should only be seen as a preventive measure, not ensuring absolute safety for devices that are regularly exposed to water.
In addition, this issue also directly affects the warranty policy. Most companies, including Google, often rule out water damage if they find wear and tear on waterproof components. This makes the responsibility for protecting the device largely belong to the user, rather than the manufacturer.
Given that reality, experts recommend that users should consider IP68 waterproofing as an additional protective layer when the device is still new.
After a few years, especially for those who use phones in harsh environments or are often exposed to water, they should consider using a specialized waterproof back cover, limit unnecessary water immersion and even replace the device to ensure safety.
Google's admission once again shows that "waterproofing" does not mean being indispensable on the device.
In the smartphone era, user caution is still a decisive factor in protecting devices and personal data from unpredictable risks.
