Corporate mobile devices travel everywhere employees go, from offices and warehouses to customer sites, airports, restaurants, and public transportation. Along the way, they collect far more than business data. Research shows that smartphones regularly accumulate bacteria, viruses, and other microorganisms through constant handling and contact with contaminated surfaces.
Studies have found that up to 94.5% of mobile phones carry bacterial contamination, making them one of the most frequently touched objects in the workplace. While many of these microorganisms are harmless to their owners, mobile devices can still transfer bacteria to shared workspaces, meeting rooms, desks, keyboards, door handles, vehicles, and other employees. For organizations managing hundreds or thousands of corporate devices, proper device sanitization should be considered part of a comprehensive mobility lifecycle strategy.
Unlike many workplace tools, smartphones rarely get cleaned. Employees carry them throughout the day, place them on public surfaces, handle them during meals, and often use them in environments with high levels of bacterial exposure.
Every touch transfers microorganisms between hands, surfaces, and devices. Over time, smartphones develop their own microbial communities based on where they travel and how they are used. While much of this bacteria comes from the user's own microbiome and is not inherently dangerous, devices also become effective carriers for spreading contaminants between people and shared workspaces.
This makes corporate smartphones, tablets, handheld scanners, rugged devices, and other mobile equipment important considerations in workplace hygiene programs.
Routine cleaning significantly reduces contamination and should be part of every organization's mobile device maintenance process. For everyday cleaning, manufacturers generally recommend using a soft microfiber cloth with appropriate cleaning solutions while avoiding excess moisture near charging ports, microphones, speakers, and other device openings.
Protective cases should also be cleaned regularly since they collect the same contaminants as the devices themselves. Routine cleaning helps reduce bacteria on the surface, but it does not fully sanitize the device.
For organizations that regularly redeploy corporate devices between employees, deeper sanitization methods are often recommended before devices are reassigned.
Ultraviolet Germicidal Irradiation (UVGI) is an industrial sanitization process that uses controlled ultraviolet-C (UV-C) light to deactivate bacteria, viruses, fungi, and other microorganisms. Rather than cleaning visible dirt, UVGI targets the DNA and RNA of microorganisms, preventing them from reproducing.
UVGI technology has been used for decades across healthcare facilities, laboratories, water treatment systems, HVAC systems, and other environments where reliable sanitization is critical.
Unlike chemical disinfectants, UVGI leaves no residue, introduces no moisture into sensitive electronics, and requires no harsh cleaning agents. This makes it particularly well suited for sanitizing smartphones, tablets, laptops, scanners, and other electronic devices that cannot tolerate excessive liquid exposure.
Enterprise organizations frequently redeploy devices between employees as part of their normal mobility lifecycle. Without proper sanitization, those devices can carry microorganisms from one user to another.
Integrating UVGI sanitization into device refurbishment and lifecycle management provides several operational benefits:
For organizations managing high-volume mobility programs, sanitization becomes another important step alongside testing, repair, quality assurance, and redeployment.
As part of its enterprise mobility lifecycle services, GoExceed incorporates UVGI sanitization into its device refurbishment process. Devices entering refurbishment are exposed to controlled UV-C light to help eliminate microorganisms before inspection, repair, testing, and redeployment.
Combined with quality testing and refurbishment, this process helps organizations safely extend the life of existing mobile devices while preparing them for the next user. Instead of replacing devices prematurely, businesses can recover additional value from their mobility investments while maintaining higher standards for device readiness and hygiene.
