Rugged smartphones are mobile devices designed for use in demanding field and industrial environments. They are distinguished by increased resistance to drops, shocks, dust, water, and extreme temperatures. They typically meet durability standards (e.g., MIL-STD-810) and have a high ingress protection rating (e.g., IP67 or IP68).

They are used in applications such as construction, logistics, industry, technical services, and emergency services. They often feature high-capacity batteries, reinforced screens, glove-friendly operation, and additional features such as barcode readers and programmable buttons. This ensures reliable communication and access to company systems even in challenging work environments.
