We have tested the new connector with multiple weights and docks, the lightning connector holds onto the iPhone a lot stronger than the old 30 pin connector.
Here’s Vapor Dock by Element Case, iPhone 5 is easily able to lift the dock in air and it won’t fall off even if you bounce it up and down.
The new docks for iPhone 5 will need to be about twice as heavy for being able to undock with one hand only. We did a weight-test and it seems you need at least 0.6 kilos (1.2 pounds) of counter-weight to be able to undock your iPhone 5 with just one hand, and even then it might bounce in the air by a tiny bit before letting go of the Lightning connector.
Here’s proof of the Vapor iPhone Dock and our magnificent advanced weighting-device weight.
530 grams = 1.2 pounds, 234 grams = 0.5 pounds.
We’ll keep an eye on iPhone 5 docks and keep you guys updated on the development.
