Anyone use a phone cooler?

[JnEricsonx]

It's one of those little USB powered fans you can clamp onto your phone, not sure if it's drawing heat away the phone, or blowing air on it point blank. In this weather, when even charging or using my phone seems to spike it's temps into the 90-100 F range, which I don't like at all, just wondering if anyone's used them and are they worth it.

Hi,
No never used one before, which phone you using ?

 

[gendo667]

Okay. Upon a Google search, the only thing I see is a fan that plugs into the charging port that appears to be made for blowing air on a person. Not to cool down a phone.

 

[gendo667]

I stand corrected. I can't even.

I have seen them but IMO, as long as the phone is operating properly, they are not needed. You can purchase some chargers that have fans if you are worry about the phone overheating when charging.

90-100°? That's roughly equivalent to body heat, and isn't going to adversely affect the phone, that's well within design parameters. A friend and I used to push our devices up into the 150-170 or so a few years ago, we just wrung em' out to the point of shutdown, sometimes, as the phones would be too hot to handle.

You don't need a fan for the temps you're describing, honestly.

 

[Mooncatt]

For these temps, no a fan isn't needed. The concept in general, though, is correct. Many gaming phones have cooling fans as an accessory or built right into the phone, and testing has shown them to be effective. Ambient temps do have a lot to do with it as well. If it's scorching hot ambient temps already, then a fan isn't going to do much good.

 

[Almeuit]

Nope. They're useless.

 

[L0n3N1nja]

A fan blows air and won't drop the temperature below ambient, considering it's summer and is often 90°F I don't think a cooler would do much.

This is also the first time I've ever heard of a fan for a mobile phone. I knew laptops had them but didn't realize phones did.

I've put one or two phones in the freezer for a few seconds to cool them down.

Fair enough, I'm just honestly paranoid about tech temps. My PC gfx card for instance is 10 years old and regularly hits the mid-high 60s C, despite people telling me that the older ones were more built to take the heat, vs being built to remove the heat.

Electronics themselves can handle a lot. The battery is the weak link, but even 100°F isn't too damaging for them.

I would never use one.
I never lay my phone in the sun.

Let it get hot.

I thought he was talking about those phone coolers bundled in those antivirus apps.

 

[N4Newbie]

Sitting out on my patio doing nothing out of the ordinary with my phone (browsing in Chrome, checking email, etc) it doesn't take long before my Pixel 4XL pops a notification along the lines of "Your phone is getting hot..."

Bright sunshine on a large screen, black phone in a black Spigen case. It all seems to add up pretty quickly.

 

[JnEricsonx]

Yeah, I've gotten that a few times once it goes over 100 F on my phone, hence my concern.

 

[bembol]

Unnecessary IMO.

Lol I do it sometimes too, when it heats up too much. I actually care very much about the battery, where the 40W mate 30 pro charger isn't the perfect thing for that. when i was camping i would put the phone on cold surfaces like metal next to the sink and it worked perfectly. I try never to exceed my body temperature (sorry. I'm too lazy to Convert Celsius to Fahrenheit)

Wonder how hot the batteries in your car get when they charge.

Lead acid batteries are capable of handling higher heat by design, so that's not a fair comparison.
