Steam from hot showers can damage 'water-resistant' smartphones, voiding warranties
Key points
- Smartphones are water-resistant, not waterproof.
- Hot steam degrades phone seals and causes internal condensation.
- Liquid damage from steam is not covered by manufacturer warranties.
- High temperatures can also impact battery health.
Understanding Water Resistance vs. Waterproof
Most modern smartphones carry an IP67 or IP68 rating, indicating water resistance, not full waterproofing. The IP rating specifies resistance to liquid water under controlled conditions, but does not account for steam or high humidity. The term "waterproof" is often misused, leading consumers to believe their devices are impervious to all forms of water exposure.
How Steam Damages Phones
In a hot shower, steam can condense into liquid water on and inside a phone. This water can penetrate through charging ports, speakers, buttons, and seals. The combination of heat and moisture gradually degrades the built-in protections, allowing liquid to enter the device. Rapid cooling in a moist environment can also create condensation both internally and externally.
Manufacturer Warnings and Warranty Limitations
Smartphone manufacturers explicitly advise against exposing devices to steam. Apple's support page, for example, warns iPhone users to avoid saunas and steam rooms, clarifying that liquid damage is not covered under warranty. Google provides similar guidance, suggesting the use of Bluetooth speakers as an alternative for audio in humid environments.
Temperature and Battery Health
Beyond water ingress, high temperatures in bathrooms, saunas, and steam rooms can exceed a smartphone's operating specifications. Most phones have a maximum operating temperature of 95 degrees Fahrenheit. Exposure to temperatures above this can trigger automatic shutdowns and negatively impact the long-term health of the device's battery.
Safer Alternatives
To prevent damage, it is recommended to keep smartphones out of humid spaces like showers. Portable Bluetooth speakers, many of which also have IP ratings, offer a more expendable and reliable alternative for listening to audio in such environments. Placing a phone near shower spray or handling it with wet hands also increases the risk of drops and water exposure.

Reporting from
Hot shower steam can damage smartphones, despite their IP ratings, because heat and humidity degrade seals and cause condensation. Manufacturers like Apple and Google explicitly state that liquid damage from steam is not covered under warranty. This information is important for smartphone users to understand the limitations of water resistance.
