Smartphones have become very fast and advanced in many aspects but very rarely does one compare their ability to withstand extreme cold temperatures. With increasing adoption of smartphones around the world, people are taking these devices in many different environments. A recent study compares different devices at sub-zero temperatures including iPhone 4S, Samsung Galaxy S II, and Nokia N9. I’m sure many of our readers in the northern hemisphere will find the results very interesting.
Apple iPhone 4S owners won’t be very pleased with the results as this latest model started experiencing problems/errors at 23 Fahrenheit (-5 Celsius). This is very serious for users living in countries with extreme cold temperatures such as Finland, Sweden, Canada, Norway and Russia. Apple claims that iPhones can function in temperatures between 0 and 35 degrees Celsius (32 to 95 degrees F). “If the phone breaks down, Apple claims they will not be responsible and it is not covered by the phone’s warranty.”
If you are a Samsung Device owner, especially Samsung Galaxy S II or Xcover, you will be very happy to know that these devices can withstand a temperature drop to -22 Fahrenheit (-30 Celsius). The AMOLED screen technology with organic diodes has proven to be superior to LCD as the liquid crystals in LCD displays tend to react slower and create ghosting effects. There are many Nokia feature phones (Nokia C1-01,C2-02, E65) with small displays and solid build quality that can survive at even lower temperatures. Check out the image below to compare different smartphones.
The main problem here is the phone batteries rather than any other component. With low temperatures, the internal resistance increases and at extreme sub-zero temperatures the phone reads the battery as empty and shuts down.
