Full iPhone 4 'Antennagate' Q&A Video Surfaces After 16 Years

I remember this pretty clearly. The issue was that Consumer Reports did a video showing how if you so much as touch the gap between the two antennas, then the cell reception drops to zero immediately every time. It was NOT about "attenuation" which happens when your entire hand covers much of the phone, causing the signal to have trouble going through your hand and dropping by a bar or two.

Memory is a funny thing; that's not what Consumer Reports found:

"Our tests found that when your finger or hand touches a spot on the phone's lower left side—an easy thing to do—the signal can significantly degrade enough to cause you to lose your connection altogether if you're in an area with a weak signal." (emphasis added).

That's "attenuation". Attenuation simply means a reduction in signal strength; it does not mean RF energy being absorbed by a person's entire hand. It is "attenuation" if you go from some bars to no bars or have a slight reduction in signal.

In cases where you had a weak signal (see below for more on this) the signal could appear to drop to 0 and in some cases drop a call, but it wasn't every time in every situation. CR even called it a "reception glitch", which is maybe a mild way of putting it.

Yes, the iPhone 4's antenna was designed poorly for certain circumstances (signal was generally great otherwise compared to other smartphones of the day) and Apple's response wasn't ideal, but the effects were not "if you so much as touch the gap between the two antennas, then the cell reception drops to zero immediately every time."

Also, if you want a deeper dive, Anandtech had a thorough analysis of the antenna and signals: https://web.archive.org/web/20100722093919/http://www.anandtech.com/show/3794/the-iphone-4-review/2

Here's part of the review:

"However, in locales that have less signal, but where iOS still displays 5 bars, the drop of 24 dB is visualized much differently. For example, at another test location, signal without holding the phone is -89 dBm, which is still displayed as 5 bars. Cup the phone, and you'll fall all the way to -113 dBm. All the bars dramatically disappear one after the other, people think they've dramatically lost all the signal, and you know the rest.

If you're at 4 bars already, (which puts you on the low end of possible signal strengths), cupping the phone even more delicately is enough to push you the remaining 10 or so dB to cutoff. It doesn't take much when you're at 4 bars, which is why the visualization is flawed. Complicating matters is that signal is completely fine until down around 2 bars at -107 dBm."

One last comment on this. While Apple was deflecting and this was not the only issue, their claim about the phone incorrectly displaying signal strength was accurate and part of the issue, as Anandtech pointed out: https://www.apple.com/newsroom/2010/07/02Letter-from-Apple-Regarding-iPhone-4

This means that people thought their signal was dropping dramatically but the reality was they were typically going from weak signal to less or no signal.

A youtube channel with a bunch of lost Apple content being called “Sir Mix-A-Lot Rare Music” is hilarious.

He was very annoyed he had to do this since he was on vacation and had to break it, according to his book.

Kind of sucks big time when you consider he resigned 11 months later due to poor health and died less than 2 months after that. This might have been one of his last chances to vacation with semi-good health. His last chance to spend quality time with his family.

So it's much deeper than just having to cut your vacation short.

Somewhat related comment.

What's interesting about this is that while the antenna design was sub-optimal (bridging the gap with a finger could cause a substantial signal drop) and Apple's response was inelegant, instructions about how to hold a phone without interfering with its antenna were common at the time.

For example, the Nokia 6230: "Use only in the normal position. Don't touch the antenna unnecessarily."

and: "Not touching the antenna area during a phone call optimises the antenna performance and the talktime of your phone."

For years cell phone manuals told people not to hold their phones in a way that interfered with the antenna. Again, that's not saying the iPhone 4 antenna was designed well for every use situation, but Apple was certainly not the only manufacturer explaining how to hold phones.
