Cell phones, especially smartphones, have become so mainstream that we no longer think about them, they are just part of our lives now. They have even become one of the items in the "pants check" before we leave the house, "Phone, wallet, keys, good to go." We can't live without it, it's our means of communication, our bank and sometimes our livelihood. But, what happens when you have to use it outside in the heat all day or leave it in the hot car for an extended period? Keep reading to see what could happen in those situations and what you can do to keep your phone cooler.
The ideal operating temperature for your cellphone or smartphone is between 32℉ and 95℉. As we learned in "What Happens When Batteries Overheat?" batteries don't like high temperatures. Pair that with all of the other electronic components in a smartphone and you have quite a sensitive piece of equipment in your pocket.
There are several reasons why your cell phone could overheat. Two of the most common reasons are:
How you use your phone and how frequently you use it can also have a major impact on the temperature of the phone. If you are on your phone all day, the battery is going to be working overtime trying to keep the screen bright, the network connected and the music playing.
Another problem that we often overlook is overcharging. Overcharging the battery will cause the battery temperature to rise, damaging the battery permanently. One way to prevent overcharging is to never leave the phone connected to a charger after the battery has reached 100%.
If all of the conditions line up just right, your phone can absolutely overheat. If your phone overheats you will start to notice several symptoms:
If you notice that your phone is starting to get warm to the touch, chances are it's even hotter inside the phone and you should try to cool it off as soon as possible.
Keeping your phone cool is important at all times, not just when it's getting too hot. Use these tips to help you keep your phone cool all the time.
Note: Do NOT put your hot phone in the refrigerator. Exposure to extreme temperature changes like this can cause moisture to build up inside the phone, causing more problems.
