What Is a Phone Farm Box? A Hardware Guide for Device Labs

A phone farm box is a regulated chassis that holds many smartphones in one enclosure — typically twenty slots — with shared power, active cooling, and a single USB path to your control PC. Instead of twenty chargers and cable nests on a desk, operators manage the fleet from one workstation.

## Core components - Chassis: Metal enclosure with slot rails, ventilation, and cable management - Centralized power: One industrial PSU replaces individual phone chargers — see our Centralized Power Module - Cooling: Front or internal fan arrays for 24/7 app testing and automation load - USB backplane: Per-slot data paths for ADB, mirroring, and batch APK deploy — USB Backplane Module for upgrades

## Desk box vs rackmount The Enterprise Phone Farm Box is the original-style standalone container for bench or shelf labs. The Rackmount Phone Farm +20 delivers the same 20-node density in a 2U module for standard 19" server racks.

## Screenless and battery-free nodes On compatible builds, removing displays and battery load improves thermal stability and power efficiency — often a 2–10% better energy profile vs full phones under continuous load. The Motherboard Box is optimized for this headless layout; full-phone boxes remain best when tests require cameras, radios, and sensors.

## What you can run on a phone farm Mobile app testing, QA automation, mobile display QA, project-isolated lab slots, remote Android control, mobile compute pipelines, and sustained SoC compute on Android nodes — anything physical phones can do at scale, with hardware you control.
