    I've been walking about an hour a day playing Pokemon Go in 100 degree weather. So naturally my iPhone 6 plus doesn't like this. Every time I walk it dims the screen to a level that I can barely see it.

    Im not complaining, I know this is an extreme condition. I'm just wondering if there is something I could do to keep it cool. I'm reluctant to take it out of its white Speck case for fear of dropping it, and I cant always feel the Pokemon vibration when I have it in my pocket.

    Mainly posting because I found it funny that this is even happening :D.

    Think this is your auto brightness setting....... Not the heat.

    No. First thing I change on my iPhone is max brightness, and auto brightness off. Its just trying to keep the components from getting damaged.

    Interesting. It gets 130 degrees here. Hit 124 last month. I work outside all day, have for years and have never had that happen. Mine does however, go right to this screen. No warnings...... Just shuts down. [​IMG]

    yeah, I've had that on my iPad before. Don't know if it matters but I'm on ios 10 beta.

    again, not really stressing me out. Phone works great, when its not in constant direct sunlight.

    Thanks for your interest.

    It matters a lot actually lol. Probably something new. At least it is to me. Could even be a bug in the auto brightness. Maybe someone else in the beta threads can confirm.

    It is hard to cool a closed device like a iPhone as it depends on the case helping to get rid of the heat. You case actually holds the heat in and with the temp outside and screen brightness set high and high CPU use, it will overheat for sure.

    Without these built in safeguards your iPhone would damage itself.

    As everyone else said, you are wrong about it being the heat.

    I've seen other posts in different threads describing the same type of behavior in relation to heat (it also doesn't seem like everyone said that that wasn't the case).

    Yep dimming screen in relation to heat is a thing. Run a gps based app in the sun and it'll do as above until it hits the ceiling to trigger the overheat screen.

    Op - buy a black golf umbrella ;)

    You aren't wrong about it being the heat, it dims the display when the phone is getting too warm. This can also be observed when playing intensive games.

    You do not need to be playing games for the phone to get too warm in the direct sun.

    Same thing happens to mine. Never had this on my smaller iphones, but you have to remember the plus has a larger surface area to attract heat

    Ok get an ice pack, probably one that you can re-freeze. Next put the iPhone in a plastic sandwich bag. Preferably ziplock type. Experiment with brands and types to find one with clearest plastic. Rubber band the plastic bag enclosed phone to the ice pack. Probably want some sort of insulating backing, foam, cloth, top off old soft side cooler etc. this way you can hold the whole thing without hand getting too cold.

    The iPhone will get hot due to hard CPU use, screen at bright, and radio chips working hard. If ambient temp is in 90s to 100s the phone turned off is already close to thermal max. Having a case on it further insulates phone from dissipating the heat.

    These are simply physical laws you can't get around. A phone with a huge finned heat sink still can't cool lower than the ambient surrounding temperature. Add placing on a hot surface, or in sunlight and you are at the limit fast. The screen will dim and finally thermal safety shutdown will occur.

    Only way is to get rid of the heat by something cooler absorbing it. In the car I will hold my phone in the air conditioning air stream of vent for a few minutes to bring temperature down. I know the rig in first paragraph is cumbersome but if you must use the phone in high ambient heat with screen at 100% to see in daylight there just is no other way.

    If you are going to "ice pack" your iPhone you better keep it in a ziplock as the higher humidity will cause moisture to condense on the cold phone and in the device and possibly set off the moisture sensors.

    Dah, try reading my post again, I specifically mention putting phone in zip lock type plastic bag.

    If you're iPhone is starting to be affected by the heat than your body may not be far behind. Maybe delay your obsession until it gets a little cooler? :D By the way, I'm not criticizing, as I have the game myself. However, I refuse to go outside extensively until its in the low 80's. That's Pokemon season.

    Put it in the freezer for 15 minutes.
    Then you will be able to catch really cool pokemons dude:D

    You didn't LOL, this only a diversion while I do my business. Everyone knows to always wrap your iPhone before using the vibrator, or ice packs.

    My phone hit a temp of 131 over the weekend and shut down with the thermometer when we went through a 115+ degree heatwave. I put it in the freezer for 5 minutes, bought it down to 85, very effective!

    Not kidding when I say you could bring an umbrella. Or just spending to shocked the device from direct sunlight. You may look like my grandma, but we actually busted out our umbrellas in Vegas two weeks ago when it was 112...

    My Asian students do this around campus all of the time in the summer months.
