Apple has admitted that all of its iPhones artificially inflate their signal strength, so that the reception the phone reports is better than the reception you're actually receiving. It blames the problem on a faulty formula. After some investigation, here's my best guess for where the formula went wrong.
Here's how Apple explains the signal-strength problem:
"Upon investigation, we were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong."
The company was stunned, absolutely stunned! I'm sure that the fact that the AT&T voice and data network delivers reception worse than strings and tin cans has nothing to do with the artificially inflated signal strength displays. Apple would never do something like that, would it?
According to the Wall Street Journal, Ross Rubin, an analyst at market research firm NPD Group, has this to say saying this about the reception deception:
"The implication is that what customers thought may have been poor reception in the past may have been worse than they believed it to be."
What formula does Apple use for calculating signal strength? It's not saying. But after some investigation, here's what I'm guessing it is:
Real signal strength X 3 = Displayed signal strength
Simple, yes? And I didn't even need a math degree to figure it out.
