    Default Sony Ericsson grip of death - iPhone 4 not the only one


    This video shows an Sony Ericsson K800i (test phone with netmonitor enabled) being given the grip of death. A test done in a few minutes. It shows at a given point up to 16 dB losses by being held tightly as we have seen people doing it on the new iPhone´╗┐ 4.

    In addition, we are comparing an old phone from 2006 with a modern wonder...

    I had a K800i for about 3 years until I bought my Nokia 5800 for Christmas. I never had any trouble making calls with it, holding it like a normal person never cut off my calls.
    Was a good phone, served me well. My brother is using it now. Hasn't even had the battery replaced and it still lasts a few days between charges.

    Haha tightly?
    Yeah sure. Dont try to defend the Iphones problem.
    The Iphone wasnt hold on "tight".

    Wow, nice test...but what exactly were you trying to prove with this video? That RF energy can be attenuated by the human body? Congratulations, ALL phones are impacted in varying degrees by this law of nature. Most modern cellphones internalize the antenna at the base of the phone, furthest away from the ear canal. If you want to impact the antenna with maximum effect with such a phone...cup the base to cover the antenna. Voila. Not rocket science.

    What you failed to demonstrate is how this relates to the dramatic drop in dB caused by capacitive interference (human touch) at the junction between the two antennas that comprise the antenna system on the iPhone 4. Although the external antenna system used in the iPhone 4 is prone to said interference, it is the particular design whereby this gap or junction is in close proximity to the heaviest part of the left palm during normal use. Some test have shown this to result in a -24dB drop in signal strength (see www.anandtech.com). In essence, this capacitive interference couples the antenna system thereby detuning the 2G/3G portion. In parallel, energy is also lost into the hand given the proximity of the antenna system during normal use (gripping by hand) If you happen to live in an area where signal strength is already low, this in turn could push the strength to a point where the phone drops calls and/or data. The only likely way around this for the iPhone 4, IMO, is with the rubber case/bumper. This serves to further separate the hand from the phone during normal use.

    Lastly, notice that with the Sony-Ericsson you can access software which allows you to get a numerical data point. With IOS4, Apple removed this feature just prior to the release of the iPhone 4. The timing of this decision, coupled with the early promotion at WWDC by Jobs of the "bumper" suggests the apparent downsides of this design choice were known by Apple well in advance of launch. IMO, the iPhone 4 is beautiful...but this beauty comes at a cost. What else is new.
