iPhone's Liquid Sensors Can Be Triggered By Wintertime Use

Posted by timothy on from the contribute-better-translation dept.

An anonymous reader writes "The Polish website Moje Jabluszko ran an experiment that proves the poor reliability of the liquid contact indicators (original, in Polish) installed by Apple in the iPhone. They performed three different tests to challenge the LCIs, which they recorded as a movie. They decided to mimic regular usage of the iPhone — meaning, you go outside where it could be cold or warm, then move inside in a building where temperature might be dramatically different, but still within covered conditions. So, they placed the iPhone in its box for one hour outside at -11 C, then moved it inside at room temperature for 24 hours. They repeated the experiment 3 times, and after the third cycle they could show that the LCI located in the audio jack plug started turning red! This is a clear proof that LCIs are not reliable and could turn red while the iPhone has been used under the defined environmental requirements defined by Apple. Here, only the condensing water could have been in contact with the sensor. In other words, even moving in and out during regular winter time will make you iPhone LCI turn red!" (In the tech specs for the iPhone, Apple rates the non-operating temperature range as -20 to 45 C.)

    We do a lot of service on macbooks at work, and there's been times when we've taking a unit in for service that "won't turn on" and the user "has no idea why", only to find out they're drippy inside, and none of the liquid sensors are tripped.

      They really have liquid sensors in them? That seems so... Orwellian. Does that not bother anyone else?

      I can't quite figure out if this is flamebait, or if I'm just the only person who can't make a connection between liquid sensors in a consumer electronic device and a dystopian police state. If a liquid sensor bothers you so much, I hate to be the one to tell you, but ... don't turn your iPhone around ... there's even a camera!

      So, no, to answer your question: it doesn't seem to bother me a bit.

      Psh, with iPhones for $40, who needs warranties?

      So my warranty is safe so long as I only use my phone in the Sahara Desert...got it.

  2. non-operating temperature range... by bsDaemon · · Score: 4, Funny

    The operating temperatures of 0 to 35C are completely held within the non-operating range of -4 to 45C. Sounds like a trick way of saying the phone isn't actually meant to work.

    Move to California.

  4. Re:What are the sensors made of? by MichaelSmith · · Score: 5, Funny

    I believe the sensor is 3M Material 5559, which is a kind of humidity indicator. Wiki says, that these are usually made from Cobalt(II) chloride, which in pure form turns from blue to red powder by absorbing water.

    Either that or the phone is pregnant.
