How to Choose the Right Mobile Computer for Your Business

When choosing an enterprise mobile computer, don’t start with the spec sheet—start with your workflows. Follow the steps below to decide which mobile computer is best for your company.

Step 1: Map Your Workflows and Environment

First, list where and how the device will be used:

• Warehouse picking and inventory → handheld or pistol-grip rugged mobile computers
• Delivery scanning and route execution → handheld or vehicle-mounted devices with GPS
• In-store retail tasks and mobile POS → lightweight handhelds or enterprise tablets
• Field inspections and maintenance → rugged handheld or tablet with offline capability

For harsh or unpredictable environments (cold storage, outdoor yards, dusty factories), look for:

• IP65/IP67 protection against dust and water
• Drop resistance and reinforced housing

This step defines the durability and form factor your mobile computer system really needs.

Step 2: Check Software and System Compatibility

Next, make sure the mobile computer will fit smoothly into your existing systems:

• Choose an operating system (Android or Windows) that your WMS, POS, ERP, or field service apps officially support.
• Confirm integration with your backend via APIs, VPN, SSO, and MDM (Mobile Device Management) tools.
• Look for enough performance to avoid lag: e.g. at least 4 GB RAM and 64 GB storage for modern enterprise apps.

If the device can’t run your core applications reliably, it’s not the right enterprise mobile computer—no matter how good the hardware looks.

Step 3: Evaluate Power, Connectivity, and Lifetime Cost

Then, focus on keeping workers online and productive for a full shift:

• Battery life: Aim for high-capacity batteries (around 5,000 mAh or more). Prefer hot-swappable batteries if you run long or back-to-back shifts.
• Connectivity: Wi-Fi 6 for dense warehouses, stores, or hospitals. 4G/5G for vehicles and field teams needing real-time data off-site. Bluetooth for pairing with printers, headsets, or additional scanners.
• Total cost of ownership (TCO): Check warranty length, service options, repair turnaround, and spare parts. Factor in cradles, chargers, pistol grips, and vehicle mounts—not just the device price.

Often, a slightly more expensive enterprise mobile computer with better lifecycle support ends up cheaper over its lifetime.

Step 4: Validate Usability with Real Users

Finally, test the device with the people who will use it every day:

• Is the device comfortable to hold and operate for an entire shift?
• Is the screen bright enough in your real environment (outdoor yards, bright stores, dim warehouses)?
• Is the touchscreen responsive with gloves or in cold conditions?
• Can a new employee learn the basic workflow in minutes, not days?

Run a small pilot with a few workers or one team. Their feedback will tell you quickly whether this is the right mobile computer for your business, or if you need to adjust form factor, size, or accessories.
