Mobile vs Desktop Speed Tests: Which Device Gives Accurate Results?
Marcus Veil — Network Engineer Apr 08, 2026 7 min read
🔬 Test Setup: 6 devices tested simultaneously, same WiFi 6E router (ASUS RT-BE88U), same 1 Gbps fiber line. Tests across 3 time periods, results averaged.
Same WiFi, 6 Different Results
Results (All via WiFi 6E, Same Router)
- Windows Desktop (wired): 924 Mbps ↓ | 911 Mbps ↑ | 5.1ms
- MacBook Air M3: 887 Mbps ↓ | 861 Mbps ↑ | 5.8ms
- iPad Pro M4: 743 Mbps ↓ | 689 Mbps ↑ | 7.2ms
- Samsung Galaxy S25: 681 Mbps ↓ | 594 Mbps ↑ | 8.4ms
- iPhone 15 Pro: 619 Mbps ↓ | 541 Mbps ↑ | 9.1ms
- Raspberry Pi 4: 312 Mbps ↓ | 289 Mbps ↑ | 6.2ms
Why Phones Show Lower Speeds
- Smaller antennas: Less signal gain = less throughput per unit time.
- Thermal throttling: Phone CPU saturates during encryption/decryption before the network does.
- WiFi chip grade: Mobile chips prioritize power efficiency over throughput.
Which Device Gives the True Speed?
A wired desktop shows the connection's true capacity. For WiFi measurement, use a laptop within 3m of the router. Phone results = "mobile experience," not connection capability. Never use phone results to dispute an ISP billing issue.
