Recently, the issue of diminishing waterproof and dustproof performance in smartphones over time has garnered renewed attention. In a recent advertisement, Google explicitly stated that its devices adhere to the IP68 rating under the IEC 60529 standard upon leaving the factory. However, the company emphasized that this protection is not permanent and that accessories do not contribute to maintaining this rating. This clarification serves as a reminder to consumers that even smartphones boasting a high level of waterproof and dustproof certification will experience a gradual decline in these protective capabilities over time.
