Using smartphones in showers or humid environments can pose risks to their water resistance and overall durability. Most current smartphones feature **IP67** or **IP68** ratings, with the second numerical digit indicating water-resistance levels. These ratings should not be confused with "waterproof," and hot steam is considered a different risk altogether. While phones are generally described as water-resistant, the term "waterproof" is often inaccurately used, leading some to believe their devices can withstand water in any scenario. In a hot shower, steam can condense into liquid, both on and around the phone. This can compromise the device's built-in protections, as water can enter through the charging port, speakers, buttons, and seals. Combined with heat, this can gradually degrade the phone's water resistance. Phone manufacturers have issued warnings about this. Apple's Support page advises iPhone owners to avoid saunas and steam rooms, noting that liquid damage is not covered under warranty. Google has issued similar advice, suggesting the use of a Bluetooth speaker instead. Water resistance ratings are specific to liquid water under certain conditions, not the heat and humid air from a shower. Rapid cooling in a moist environment can create condensation inside and outside the device. Additionally, overly hot bathrooms, saunas, and steam rooms can exceed a smartphone's operating temperature limits, which are typically around 95 degrees. Exceeding this can lead to temperature shutdowns and negatively impact the battery's long-term health. Placing a phone on a shower shelf or soap dish, especially near the spray, increases the risk of exposure to water and drops. Handling a wet phone can also lead to accidents. To mitigate these risks, it is recommended to keep the phone outside the bathroom if possible and use a portable Bluetooth speaker. Many Bluetooth speakers have the same IP ratings as smartphones and are more expendable. Heat exposure can cause permanent damage to a smartphone. Repeated or significant exposure to heat can accelerate battery aging and affect the adhesives and seals that protect the device. The damage is often not immediately obvious, with potential issues such as liquid damage alerts or the need to use a magnetic charger while the port dries. If a phone gets wet, it should be wiped down immediately, and nothing should be plugged into the charging port. The ports should be facing downward, and methods such as using a hairdryer or placing the phone in a bowl of rice should be avoided. Apple specifically recommends against using rice. To prevent damage, it is best to avoid getting the phone wet in the first place. This includes keeping it out of hot, humid environments. Using a portable Bluetooth speaker can allow users to enjoy music or audiobooks while keeping their phone safe in another room. Given the cost of smartphones, avoiding exposure to heat and moisture is advisable.
