Mobile phone overuse (mobile-phone addiction, problem mobile phone use, or mobile phone dependency) is a dependence syndrome seen among certain mobile phone users. Some mobile phone users exhibit problematic behaviors related to substance use disorders. These behaviors can include preoccupation with mobile communication, excessive money or time spent on mobile phones, use of mobile phones in socially or physically inappropriate situations such as driving an automobile. Increased use can also lead to increased time on mobile communication, adverse effects on relationships, and anxiety if separated from a mobile phone or sufficient signal.[citation needed]



Overuse is often defined as a "dependence syndrome," which is the term used by the World Health Organization (WHO Expert Committee, 1964) to replace addiction or habituation.[1] This is categorised either as substance abuse, such as from psychoactive drugs, alcohol and tobacco under ICD-10, or a behavioral addiction, such as a mobile phone addiction.[2]

Substance use disorders can be defined by 11 factors, according to the DSM-5, including: (1) use in larger quantities or for longer than initially intended, (2) a desire to cut down or control use, (3) spending a great deal of time obtaining, using, or recovering from the substance, (4) craving, (8) use in situations in which it is physically hazardous, (9) continued use of the substance despite adverse physical or psychological consequences associated with use, and (11) withdrawal symptoms.[3]

Smartphone addiction can be compared to substance use disorders in that smartphones provide the drug (entertainment and connection) while acting as the means by which the drug is consumed. A study conducted at Alabama State University on the effects of smartphones on students, defines the issue by stating that we are not addicted to smartphones themselves, but that we "are addicted to the information, entertainment, and personal connections [that a smartphone] delivers."[4] People have an affinity for constant entertainment, and smartphones provide the quickest, most easily accessible route to it.

Prevalence of mobile phone overuse depends largely on definition and thus the scales used to quantify a subject's behaviors. Two scales are in use, the 20-item self-reported Problematic Use of Mobile Phones (PUMP) scale,[5] and the Mobile Phone Problem Use Scale (MPPUS), which have been used both with adult and adolescent populations. There are variations in the age, gender and percentage of the population affected problematically according to the scales and definitions used. The prevalence among British adolescents aged 11–14 was 10%.[6] In India, addiction is stated at 39-44% for this age group.[2] Under different diagnostic criteria, the estimated prevalence ranges from 0 to 38%, with self-attribution of mobile phone addiction exceeding the prevalence estimated in the studies themselves.[7] The prevalence of the related problem of Internet addiction was 4.9-10.7% in Korea, and is now regarded as a serious public health issue.[8]

Behaviors associated with mobile-phone addiction differ between genders.[9] Women are more likely to develop addictive mobile phone behavior than men. Men experience less social stress than women and use their mobile phones less for social purposes. Older people are less likely to develop addictive mobile phone behavior because of different social usage, stress and greater self-regulation.[10]


Overuse of mobile phones can affect social and psychological well-being and health.[11]


There is an enormous impact of the mobile phone on contemporary society from a social scientific perspective. In his 2017 book Perpetual contact: mobile communication, private talk, public performance[12] the author, James Katz, writes: "They [mobile phones] have transformed social practices and changed the way we do business, yet surprisingly we have little perception on their effect in our li[ves]."

Some people are replacing face-to-face conversations with cybernetic ones. Clinical psychologist Lisa Merlo says, "Some patients pretend to talk on the phone or fiddle with apps to avoid eye contact or other interactions at a party."[13] In a survey made by Gazelle, "More than 25% of respondents reported that they 'almost always' use their smartphone while in a social setting such as during a meal or during a party. In addition, 58% said they use it 'usually' or 'occasionally' during these settings."[14] Furthermore,

  • 70% check their phones in the morning within an hour of getting up.
  • 56% check their phones before going to bed.
  • 48% check their phones over the weekend.
  • 51% constantly check their phones during vacation.
  • 44% reported they would feel very anxious and irritable if they did not interact with their phones within a week.[15]

This change in style from face-to-face to text-based conversation has also been observed by Sherry Turkle. Her work cites connectivity as an important trigger of social behavior change regarding communication;[16] therefore, this adaptation of communicating is not caused only by the phone itself. In her book, Alone Together: Why We Expect More from Technology and Less from Each Other, Turkle argues that we now find ourselves in a state of "continual co-presence."[17] This means that digital communication allows the occurrence of two or more realities in the same place and time. Subsequently, we also live in a "world of continual partial attention,"[17] the process of paying simultaneous attention to a number of sources of incoming information, but at a superficial level. Bombarded with an abundance of emails, texts, messages, we not only find ourselves divesting people of their human characteristics or individuality, but also increasingly treating them as digital units. This is often referred to as depersonalization.[18]

Other implications of cell phone use in mental health symptoms were observed by Thomée et al. in Sweden. This study found a relationship between report of mental health and perceived stress of participants' accessibility, which is defined as the possibility to be disturbed at any moment of day or night.[19]


There is some evidence supporting the claim that excessive mobile phone use can cause or worsen health problems.

Germs are everywhere, and considering the number of times people interact with their cellphone under different circumstances and places, germs are very likely to transfer from one place to another. Research from the London School of Hygiene & Tropical Medicine at Queen Mary in 2011 indicated that one in six cell phones is contaminated with fecal matter. Under further inspection, some of the phones with the fecal matter were also harboring lethal bacteria such as E. coli, which can result in fever, vomiting, and diarrhea.[20]

According to the article Mobile Phones and Nosocomial Infections, written by researchers at Mansoura University of Egypt, it states that the risk of transmitting the bacteria by the medical staff (who carry their cellphones during their shift) is much higher because cellphones act as a reservoir where the bacteria can thrive.[21][22]

Cancer, specifically brain cancer, and its correlation with phone use, is under ongoing investigation. Many variables affect the likelihood of hosting cancerous cells, including how long and how frequently people use their phones. There has been no definitive evidence linking cancer and phone use if used moderately, but the International Agency for Research on Cancer of the World Health Organization said in 2011 that radio frequency is a possible human carcinogen, based on heavy usage increasing the risk of developing glioma tumors.[23] Although a relationship has not been fully established, research is continuing based on leads from changing patterns of mobile phone use over time and habits of phone users.[24] Low level radio frequency radiation has also been confirmed as a promoter of tumors in mice.[25] Minor acute immediate effects of radio frequency exposure have long been known such as the Microwave auditory effect which was discovered in 1962.[26]

Studies show that users often associate using a mobile phone with headaches, impaired memory and concentration, fatigue, dizziness and disturbed sleep.[27] There are also concerns that some people may develop electrosensitivity from excessive exposure to electromagnetic fields, although these symptoms may be primarily psychological in origin due to the nocebo effect.[28][29]

Using a cell phone before bed can cause insomnia, according to a study by scientists from the Karolinska Institute and Uppsala University in Sweden and from Wayne State University in Michigan. The study[30] showed that this is due to the radiation received by the user as stated, "The study indicates that during laboratory exposure to 884 MHz wireless signals, components of sleep believed to be important for recovery from daily wear and tear are adversely affected." Additional adverse health effects attributable to smartphone usage include a diminished quantity and quality of sleep due to an inhibited secretion of melatonin.[31]

In 2014, 58% of World Health Organization states advised the general population to reduce radio frequency exposure below heating guidelines. The most common advice is to use hands-free kits (69%), to reduce call time (44%), use text messaging (36%), avoid calling with low signals (24%) or use phones with low specific absorption rate (SAR) (22%).[32] In 2015 Taiwan banned toddlers under the age of two from using mobile phones or any similar electronic devices, and France banned WiFi from toddlers' nurseries.[33][34]

As the market increases to grow, more light is being shed upon the accompanying behavioural health issues and how mobile phones can be problematic. Mobile phones continue to become increasingly multifunctional and sophisticated, which this in turn worsens the problem.[35]


There are concerns that some mobile phone users incur considerable debt, and that mobile phones are being used to violate privacy and harass others.[36] In particular, there is increasing evidence that mobile phones are being used as a tool by children to bully other children.[37]

There is a large amount of research on mobile phone use, and its positive and negative influence on the human's psychological mind and social communication. Mobile phone users may encounter stress, sleep disturbances and symptoms of depression, especially young adults.[38] Consistent phone use can cause a chain reaction, affecting one aspect of a user's life and expanding to contaminate the rest. It usually starts with social disorders, which can lead to depression and stress and ultimately affect lifestyle habits such as sleeping right and eating right.[19]

According to research done by Jean M. Twenge, a professor of psychology at San Diego State University, there is a correlation between mobile phone overuse and depression. According to Twenge and her colleagues, at the same time that smartphones were on the rise, there was also an increase seen in depressive symptoms and even suicides among adolescents in 2010.[39] The theory behind this research is that adolescents who are being raised as a generation of avid smartphone users are spending so much time on these devices that they forgo actual human interaction which is seen as essential to mental health, “The more time teens spend looking at screens, the more likely they are to report symptoms of depression.”[40] While children used to spend their free time outdoors with others, with the advancement of technology, this free time is seemingly now being spent more on mobile devices.

Children these days are missing out on outdoor play and the chance to let their imagination grow because they are constantly playing games and snapchatting. Psychologist Nancy Colier makes the point that we all have lost sight of what is truly important to us in life. She says that people have become “disconnected from what really matters, from what makes us feel nourished and grounded as human beings.” [41] Our addiction to technology has deterred neurological and relationship development because tech is being introduced to people at a very young age. People have become so addicted to their phones that they are almost dependent on them. Our bodies are not meant to be constantly staring at a screen as we need time to relax our eyes and more importantly our minds. Colier states,  “Without open spaces and downtime, the nervous system never shuts down — it’s in constant fight-or-flight mode. “We’re wired and tired all the time. Even computers reboot, but we’re not doing it.”[41]

However, while it is easy to see a correlation between cell phone overuse and these symptoms of depression, anxiety, and isolation, it is much harder to prove that cell phones themselves cause these issues. Studies of correlations cannot prove causation because there are multiple other factors that increase depression in people today. Although parents and other figures share these concerns, according to Peter Etchells, a psychologist at Bath Spa University in England, other possible variables must be reviewed as well. Etchells proposes two possible alternative theories: depression could cause teens to use iphones more or teens could be more open to discussing the topic of depression in this day and age. [42]

Distracted drivingEdit

Mobile phone overuse can be especially dangerous in certain situations such as texting and driving or talking on the phone while driving. Over 8 people are killed and 1,161 are injured daily because of distracted driving.[43] At any given daylight moment across America, approximately 660,000 drivers are using cell phones or electronic devices while driving.[43] The significant number of injuries and accidents from distracted driving can be contributed at least partially to mobile phone overuse. There is currently no national ban on texting while driving, but many states have implemented laws to try to prevent these accidents.[43]


German psychotherapist and online addiction expert Bert te Wildt recommends using tools such as Offtime and Menthal to help prevent mobile phone overuse.[44]

Many smartphone addiction activists (such as Tristan Harris) recommend turning your phone screen to grayscale mode, which helps reduce time spent on mobile phones by making them boring to look at. [45]

In popular cultureEdit

Personalities such as Amy Borkowsky are popularising and challenging the assumed level of dependence on and necessity of mobile telephones by having mobile telephone free periods.
