iPhone OS 4.0.1 Signal Strength Display Change Graphics

Thursday, 15 July 2010

Apple just released the iPhone 4.0.1 update that changes the way signal strength is displayed. The new graph looks pretty weird to me since it's no longer linear. I made some quick graphics of the changes:

To make the change easier to visualize, I did some combo graphics. The first is an overlay where the red represents the new bars and the second is an animation showing old and new states:

Apparently the bars themselves now also represent a more accurate depiction of signal strength. AnandTech has a detailed write up of the changes. I've noticed that where I have normally gotten the full five bars at my office, I am now hovering around four, with the occasional 5.
