New Study Reveals How Long Coronavirus Can Live On A Smartphone 

Nowadays everyone has a smartphone. It is the most used gadget for everyone. Given the fact that smartphones are used widely and we touch the body part and surfaces of the phone million times in a day, we must know that this makes a smartphone the most exposed gadget to germs and viruses. Given the outbreak of Covid-19 disease, there have been serious concerns about smartphones being exposed to the virus as well. Some of the major concerns are – how likely is it for a person to catch the virus from their smartphone, or how long does coronavirus stay on a smartphone. In order to calculate the risk factor, we will see how long the novel coronavirus can stay on a smartphone surface.


According to the reports presented by the World Health Organization (WHO), the original SARS-CoV virus which was found in 2003 was stable on a glass surface for up to 96 hours (four days). Apart from glass, it lasted on hard plastic and stainless steel for about 72 hours (three days). Currently, the recent study from the United States’ National Institutes of Health revealed that the current novel coronavirus (SARS-CoV-2) can live on surfaces like steel and hard plastic for about 72 hours (three days), same as the SARS-CoV virus. The study also said that the novel coronavirus can last on a cardboard surface for about 24 hours and about 4 hours on copper. Now, since the new NIH study did not factor in how long the virus stays on glass, other factors do point at similar results as the previous SARS coronavirus.

Hence, combining the WHO study of 2003 and the NIH study from this month, we can assume that the novel coronavirus can stay on glass for up to 96 hours (four days). And since almost all smartphones come with a glass panel upfront, we can assume that the coronavirus can stay on a smartphone for up to four days. Not just smartphones, this applies to any gadget with a glass surface be it a smartphone, a smartwatch, a tablet, or a laptop.


Now, out of all of these gadgets, the smartphone still remains the most exposed gadget. We must be cautious and clean our phones every now and then so that it can be avoided by coronavirus. There are various ways by which you can clean the smartphone. You can either use a cleaning liquid for smartphones/ gadgets or just wipe the surface with a slightly wet microfibre cloth. To sanitise it, it’s best to use a 70 percent isopropyl alcohol solution or disinfecting wipes. One should be careful not to use concentrations higher than 70 percent, or other disinfectant liquids, as these can destroy the oleophobic coating on your smartphone’s display. You can also install a screen protector, and clean that instead so that you don’t damage the display coating.


“Using a 70 percent isopropyl alcohol wipe or Clorox Disinfecting Wipes, you may gently wipe the hard, nonporous surfaces of your Apple product, such as the display, keyboard, or other exterior surfaces. Don’t use bleach. Avoid getting moisture in any opening, and don’t submerge your Apple product in any cleaning agents. Don’t use on fabric or leather surfaces,” Apple recommends on its support page.
