Importance of USB version in Android Developer’s life
I was getting very irritated while waiting for apk to get installed on my testing device because it was taking longer than expected. So I started changing device and tested it. Then I found that I was not using USB 3.0 cable even though my device supports it.
I tried to measure some apk install time on my devices.
Here are the findings :
Case 1
Phone : Redmi 4 — Snapgragon 435 , 4 GB RAM , eMMC 5.1 internal memory
Interface : micro USB 2.0
Laptop Interface : USB 3.0
Cable Used : Mi micro USB 2.0 cable speed up to 480 Mbps.
It took ~57s for transfer + installation through adb.
I tested it again;
It again took ~57s for transfer + installation through adb.
Case 2
Phone : Oneplus 7T— Snapgragon 855+ , 8GB RAM , UFS 3.0 internal memory
Interface : 3.1, Type-C
Laptop Interface : USB 3.0
Cable Used : Mi Type -C USB 2.0 cable speed up to 480 Mbps
It took ~18s for transfer + installation through adb.
I tested it again;
It again took ~18s for transfer + installation through adb.
Case 3
Phone : Oneplus 7T — Snapgragon 855+ , 8GB RAM , UFS 3.0 internal memory
Phone Interface : 3.1, Type-C
Laptop Interface : USB 3.0
Cable Used : AmazonBasics USB Type-C 3.1 Gen2 USB 3.0 cable, speed up to 5 Gbps.
It took ~12s for transfer + installation through adb.
I tested it again;
It again took ~12s for transfer + installation through adb.
Conclusion
Always use
- Better device with USB latest gen. interface
- USB latest gen. cable
- USB latest gen. laptop interface
for testing so that it will take less time and you will not be irritated.
Few Points to note :
- Even though Oneplus 7T have USB 3.1 Type C interface, it was provided with USB 2.0 Type C cable.
- Even though Macbook Pro 2019 have USB 3.1 Gen 2 Type-C port, cable provided with their charger is USB 2.0 one.
- USB 3.1 supports up to 10Gbps

Thank you for reading this article.
Update#1
Even though I was using Honeywell Type C to USB 3.0 Adapter with Gigabit Ethernet which supports only USB 3.0, I am getting 10Gbps transfer speed because Macbook Pro support USB 3.1 Gen2. So I think USB hub doesn't have difference in USB 3.0 and 3.1.
Difference of close to ~30 seconds :O
