Cold weather and smartphone ?

[mechanictim]

I have a Tracphone that I keep in my vehicle all the time. This past June I got a ZTE Valet phone to replace an older Kyocera. I did some looking on google and found articles on cold weather and smart phones that said the phone will be OK to some fairly cold temps and would start to work if warmed up after going below those temps. Just wondering if anyone else has tried long term cold storage of phone and had any issues?

The articles I read said that the battery would show less of a charge the colder it got and the screen would freeze up and become unresponsive the colder it got. But I am looking at keeping the phone outdoors all winter. I figure if I need the phone I can just put it in an inside pocket and warm it up for a few minutes.

with my iPhone this Fall deer hunting it got cold sitting in an exposed pocket. It gave me a message it was "too hot" and turned off (maybe phone hypothermia?) and didn't work even though I put it in a pocket that was near my body. It worked when I got back to the cabin after a while. I wouldn't count on the putting in your pocket idea especially in an emergency.

Cold weather and batteries are for sure a bad thing. I am not sure about the smartphone getting cold and not working, but it might. I know I have had laptops not works so well when left outside overnight, I had figured the cold wouldn't have that much effect on electronics, so I was rather surprised. Once it warmed up it was OK.

It wasn't that long ago I watched bit on TV about cold weather, electronics (smartphones in particular ) and the recommended operating temps the manufactures set for their products. They talked about weird errors, condensation inside the device that will eventually lead to its failure, components that would shatter, including the screen at very cold temps.

It was pretty interesting and it also make you think back a few years when a lot of Lowrance depthfinders were failing left and right, how many of those devices are left mounted on the boat ( winter storage ), snowmobiles and / or ATV during winter that were not meant to be out in that type of weather

I also found this article that was published last January when the ' polar vortex ' was gripping the U.S.

Stepping into the bitter cold, you may have noticed such bodily effects as numbing of the extremities and difficulty breathing. But people are not alone in battling the effects of the cold. Some of our most prized possessions also react to the dipping thermostat: our mobile devices.

Smartphones are known to withstand cold temperatures much better than hot; however, extreme cold temperatures can have adverse effects on our favorite gadgets. Studies have shown that many Android devices fare better in the cold than Apple devices, but smartphones across the board appear to succumb equally at about -40 Degrees, where all functionality ceases.

Though it may just feel like its -40 out, recent temperatures are actually low enough to elicit negative effects on smartphones. Here’s a list of issues than can arise in your smartphone due to the cold.

Battery drain/death

Battery drain is one of the most immediate effects of cold weather. Devices may spontaneously shut down with a dead battery in the extreme cold. Over time, extended exposure to cold temperatures can kill a smartphone battery all together.

Screen issues

Smartphones with LCD displays are more susceptible to the cold than those with AMOLED displays. With LCD displays in particular, users may experience delayed touchscreen reactions as well as smudging and ghosting of text and colors. Display panels are also more susceptible to shattering when dropped as the cold makes the panel rigid.

Internal component errors

In extreme cold temperatures smartphones may begin to register various errors of a their internal components. Devices may have difficulty reading a SIM card or executing a number processing functionalities.

Physical damage to internal and external components

As said, extreme cold causes components of smartphones, both internal and external, to become rigid, which could lead to physical damage like spontaneous screen shattering. Drops or blunt movements can also crack a screen and dislodge or damage internal components. Devices left in extreme cold temperatures for an extended time can be susceptible to permanent damage, especially when left in ‘sleep mode.’

Liquid condensation

Smartphones are susceptible to liquid condensation underneath their displays if they are used soon after being brought into a warm area after an extended time in the cold. This can cause various liquid damage issues and can also make the screen hard to read.

Tips to protect your smartphone from the cold

Don’t take your smartphone out in the cold/limit use in the cold. Leave your smartphone in your pocket, jacket, bag or purse. Leaving devices in a pocket close to your own body heat is most recommended.

Protect your smartphone with a heavy duty, weatherproof case such as an OtterBox or Lifeproof case. Such cases are dirt proof, waterproof and drop resistant.

Use warming gloves when handling a smartphone in the cold. Whether gloves are warmed or not, protecting yourself in the cold will also help prevent accidental drops due to your own physical reactions to the cold.

Don’t leave your smartphone in a cold vehicle for extended periods of time, especially not overnight. Such extended use can cause permanent internal and external damage.

Keep your smartphone away from or protected from snow related activities such as shoveling or sledding. In addition to the cold, the opportunity for the device to get wet is also great and extremely damaging.

Use headphones or a Bluetooth earbud and mic in order to keep smartphones put away while out in the cold. Not only do many Bluetooth devices have call answer buttons, many smartphones have quick answer options, which will allow users to take calls without handling the device.

Charge your smartphone before going outside. If your battery is fully before going out into the cold, it is less likely to experience battery drain. Keep a mobile charger around for long trips as well as an extra battery for backup.

What to do if your smartphone is exposed to extreme cold

If your smartphone happens to be exposed to extreme cold, the best thing to do is to turn the device off and allow it to warm back up to room temperature before turning it on again for use. This not only helps prevent condensation, but also helps prevent any other damage that might occur while the device is warming up.

Battery is probably the biggest worry, it will shorten the life and capacity of it. Extremely cold it might damage the screen. But in general, the rest of the components will just be fine in the cold.
