    I live in South Florida, it's hot 75% of the year here and the humidity is just as bad. I just got the cheap $1.99 vent mount for my EVO and love it but I noticed with direct vent exposure the screen tends to fog up and the battery temps drop as expected. Now is there any major issue with this? Will I see any problems down the road with the screen or internals because of the condonsation? I've since closed off the vent that holds the phone and it seems to be working but I kinda liked seeing low low battery temps and was just wondering... :)

    The cold won't bother it, your A/C isn't going to get nearly cold enough to have that kind of impact.

    The condensation could though, depending on how bad it is. They're designed to handle a certain level of condensation/humidity, but hard to tell how much you're getting.

    i dont think you have to worry...

    either it is ok..
    all EVO will be screwed in winter time!! much colder than your AC can do!

    The fogging should only be temporary until the phone equalizes to the ambient temp. Having over the vent should actually keep the internals drier after a while. I'm in Miami and I have a windsheild mount that sits over a vent. Used my pre for over a year and now the evo for over a month with no issues.

    I also mount mine on the A/C (I live in Eastern NC so I know all about heat and humidity during the summer.) I've yet to notice any issues from the moisture. I do however give my EVO a second or two to warm up before immediately opening the door into the heat. Something about moving hardware from extreme cold to extreme heat doesn't seem like a good idea to me.
  6. Why not just turn that vent off?

    As others have said, the cold isnt going to hurt it, actually it will help. If you are getting condensation, thats not good at all.

    dude, you actually doing good to your phone....

    Lithium-ion batteries main enemy and culprit is heat.. the more heat the more damage it will do and the less life the battery will have... if you can drop the temps on the battery, it will increase its life and will perform better.

    in other words, there is nothing wrong, but good
  8. And again, yes the cold is fine, but the condensation is very bad. Any moisture will short it out, and probably actuvate the moisture sensors and void the warranty.

    This is why I posted the thread. :)

    And to the guy who said just turn off the vent.. I drive a 2004 chevrolet colorado not the fanciest vehicle on the market but the best I can do is slide the vent closed but air does still leak out and since the phone is so close it still gets minor effects.

    I've been having good results the past few days having the phone up there but the vent slid closed. Seeing around 75 as the normal running temp while mounted. Tried this morning to drop it looooooooow and it got down to 55 and I decided thats enough and slowly brought it back up to a normal temp. It's kinda fun, I mean i've got insurance so if it really gets f'ed i'll just do the old "I dunno where it went trick" and pay the $100 for a new one. Odds are by what everyones saying i'll be fine. Thanks.

    which will bring us to the next step


    the driver has the change to turn the fan speed down, and turn the AC temp up a bit. it doesnt need to be on MAX A/C all the time... i can see it for the first 10 minutes of driving, but after the temp inside the cabin drops, u can easily put it on 1 and work with temp

    or he has to much humidity inside the vehicle....

    BESIDES, lets take a look at how condensation really forms... Condensation forms when water molecules in relatively warm air come into contact with a cold surface. As the molecules cool down, they begin to move about more slowly and draw closer together. If they are cooled down enough, they begin to stick together -- they no longer have the energy to overcome their natural attraction for one another.

    so if the OP recycles the air inside the cabin which is already cool, he should not be getting any condensation at all

    I would be careful OP. My original iphone stopped working after some condensation formed on the screen at a pool in florida. It never touched water but the screen stopped responding to touch permanently.

    Okay, so I have the reverse question. I've been thinking about getting some sort of vent holder for my phone, but I live in MN. It's really cold here and I can't imagine closing a vent that was within reach of my while driving when it's 20 or more degrees below zero. Do you think a vent holder plus heat out of the vents will be a problem?
