Apple's bumper case improves antenna performance

After the Antennagate affair of a few months ago where it was revealed that if you held the new iPhone 4 a certain way the signal would drop out, and the resulting storm that hit the international media when Apple supremo Steve Jobs reported sent an angry customer an email telling him not to hold it that way, it would appear that the free bumpers Apple has shipped to consumers are having quite the opposite effect for the handsets.

In research conducted by NeoWin they have discovered that iPhone 4 signal performance actually increases slightly with the bumpers on.

None of this should come as any great surprise as a Human hand can be used as a conductor and as a medium that can both disrupt and absorb radio and electrical signals.  Placing a non-conductive material between a person's hand and the phone would negate any negative effects cause by this.

The benefits are marginal as I've said but they do highlight that sometimes a case of any description can help improve the signal quality of a phone, in addition to protecting it and prolonging its life.  This is something that mobile handset manufacturers seem to be letting slip during the design and development process for new handsets, as the pressure is on to make them ever thinner and lighter.

Research such as this, however unscientific it may have been and however handset manufacturers may refute it, is an excellent example of how they can and should look again at the development of new handsets to try and negate signal drop out and other problems, through simple changes and amendments to a mobile phone's design.  It's very likely that comsumers would happily accept a phone that was a little bit thicker in exchange for this type of performance improvement.

    Martin, I would appreciate that you do not censor this post, as it’s informative writing.

    Onur, there is a misleading statement “[…] GIFs are animated images …”. No, obviously you don’t seem to have take much notice of what you were told back in March regarding; Graphics Interchange Format (GIF).

    For example, https://www.ghacks.net/2023/03/31/whats-gif-explanation-and-how-to-use-it/#comment-4562919 (if you had read my replies within that thread, you might have learnt something useful). I even mentioned, “GIF intrinsically supports animated images (GIF89a)”.

    You linked to said article, [Related: …] within this article, but have somehow failed to take onboard what support you were given by several more knowledgeable people.

    If you used AI to help write this article, it has failed miserably.

      EMRE ÇITAK posts are useless because they are fraught with inaccuracies and are irrelevant.

    AI is stupid, and it will not get any better if we really know how this all works. Prove me wrong.. https://www.youtube.com/watch?v=4IYl1sTIOHI

    Martin, [#comment-4569908] is only meant to be in: [https://www.ghacks.net/2023/07/09/how-to-send-gifs-on-iphone-two-different-ways/]. Whereas it appears duplicated in several recent random low-quality non relevant articles.

    Obviously it [#comment-4569908] was posted: 9 July 2023. Long before this thread even existed… your database is falling over. Those comments are supposed to have unique ID values. It shouldn’t be possible to duplicate the post ID, if the database had referential integrity.

    GateKeeper ?

    That’s called “appointing” businesses to do the state’s dirty work!!!!!

    But the article says itself that those appointed were not happy – implying they had not choice!!!!!!

    Note: I replaced the quoted URI scheme: https:// with “>>” and posted.

    The current ghacks.net is owned by “Softonic International S.A.” (sold by Martin in October 2019), and due to the fate of M&A, ghacks.net has changed in quality.

    Many Authors of bloggers and advertisers certified by Softonic have joined the site, and the site is full of articles aimed at advertising and clickbait.

    As it stands, except for articles by Martin Brinkmann, Mike Turcotte, and Ashwin, they are low quality, unhelpful, and even vicious. It is better not to read those articles.

    By the way, if you use an RSS reader, you can track exactly where your comments are (I’m an iPad user, so I use “Feedly Classic”, but for Windows I prefer the desktop app “RSS Guard”).

    We all live in digital surveillance glass houses under scrutiny of evil people because of people like Musk. It’s only fair that he takes his turn.

    “Operating systems will be required to let the user choose the browser, virtual assistant and search engine of their choice. Microsoft cannot force users to use Bing or Edge. Apple will have to open up its iOS operating system to allow third-party app stores, aka allow sideloading of apps. Google, on the other hand, will need to provide users with the ability to uninstall preloaded apps (bloatware) from Android devices. Online services will need to allow users to unsubscribe from their platform easily. Gatekeepers need to provide interoperability with third-parties that offer similar services.”

    Wonderful ! Let’s hope they’ll comply with that law more than they are doing with the GDPR.

    yeah sure… they are always the victims and it is only against them ????

    Believe them 100% and never question anything. This lawsuit sounds like the type you heard when people were eating batteries.
