A substantial majority of Americans are cellphone owners across a wide range of demographic groups. By contrast, smartphone ownership exhibits greater variation based on age, household income and educational attainment.

This is normal. The phone temperature increases with the process of charging and phone usage. The phone will self regulate and only request power as it needs it. The charger does not force energy into the phone.

Some phones have built-in thermal protection to conserve battery life when they get hot. This is normal behavior for the phone and not a defect of the charging pad or pocket. Closing background apps may help the phone use up less energy.

In fact, your own hand is the biggest culprit when it comes to putting filth on your phone. Americans check their phones about 47 times per day, according to a survey by Deloitte, which affords plenty of opportunities for microorganisms to move from your fingers to your phone.

Deleterious effects of smartphones on attention are particularly concerning in situations where attention is crucial for safety, such as in the case of distracted driving. A substantial body of work over the past 12 years has considered the effects of texting on driving abilities using driving simulators or closed tracks. Caird et al. (2014) performed a meta-analysis on this literature and concluded that the act of writing text messages impacts nearly every studied measure of dangerous driving. They reported that texting consistently led to decreased attention to the road, slower response time to hazards, greater lateral variance across the lane, and more crashes. Reading text messages without responding resulted in similar findings, albeit with smaller effect sizes. These findings are particularly troubling given that 31% of adults surveyed in 2011, and 42% of teen drivers surveyed in 2015, reported that they had read or sent text messages while driving in the past 30 days (Centers for Disease Control and Prevention, 2011, 2016).

Extending this work on sleep, Lemola et al. (2014) used self-report questionnaires to explore how sleep and smartphone habits might also impact mood; specifically depressive symptoms. They found that difficulty sleeping was a significant mediator in the relationship between electronic media use and depressive symptoms. While psychopathological symptoms are not the focus of this paper, it is noteworthy that depression is often comorbid with cognitive disorders (American Psychiatric Association, 2013), and that sleep quality is inversely related with cognitive performance (Lim and Dinges, 2008).

Although the research concerning the potential cognitive impacts of smartphone technology is growing, the results remain contradictory and inconclusive. The at times contradictory findings suggest that not all smartphone use is created equal; certain apps, approaches to multitasking, or notification settings may moderate the relation between overall smartphone use and various cognitive skills. Despite the inconclusive nature of the literature, media headlines encourage a public perception that the findings are conclusive and that smartphones have a definite and negative impact on cognitive functioning. A common view, that smartphones are stifling our creativity by depriving our brains of downtime (Richtel, 2010a), even led to a radio challenge, in which thousands of people reduced their smartphone usage in an attempt to increase their creativity (Zomorodi, 2015). However, there is no extant research to validate the basic concern that motivated the challenge. Investigating the cognitive impacts of filling the small breaks in our day with inputs from smartphone engagement is perhaps another endeavor worth pursuing, but not one that is yet represented in the peer reviewed literature.

As discussed earlier in our review, there are many limitations to the literature that forms the basis for this paper. Chief among these is that there is very little longitudinal evidence on the long-term consequences of frequent smartphone usage. Now is the time to begin gathering the data for such studies. A particularly important topic that requires longitudinal data is the effect of smartphone ownership on young children. Despite widely publicized recommendations (AAP Council on Communications and Media, 2016a,b), we know very little about the most appropriate age for a child to begin using a smartphone, and we know equally little about the consequences of using one too early in life. A longitudinal study with a large sample size should be developed in which children are assessed on a variety of cognitive (and affective) outcome measures at multiple time points. In a study such as this, data could also be gathered to ascertain the degree to which children with smartphones or other portable sources of immediate gratification, such as portable video game systems, are influenced by these devices. Analysis of group differences in rates of maturity of certain cognitive processes could also provide information about how smartphone technology can affect the brain during periods of heightened developmental plasticity. It is possible, but untested, that frequent smartphone usage could be less harmful to adults, whereas children may experience more negative consequences as a result of their increased neural plasticity.

As smartphones have worked their way into the pockets of over 70% of American adults, and nearly 50% of adults worldwide, there is also a great opportunity to use them as a tool for research (Poushter, 2016). Scientists have already begun to suggest that smartphones could present a more convenient and more naturalistic method of gathering empirical data for cognitive and social psychology experiments (Raento et al., 2009; Dufau et al., 2011; Miller, 2012). Moreover, as smartphones become increasingly interlaced with our cognitive functioning, it will be important to continue to gather detailed usage metrics to understand how these interactions are affecting us, and how are lives are accordingly shaped.

Other factors come into play as well. Since B2B buyers use their phones to engage early in formulating buying intent, search, video, email, and social media are all important functions for marketers to get right in a mobile context. The B2B purchase process can be long and complex, so high-quality, personalized content, delivered throughout the buying journey, is an important differentiator. And because B2B purchasing is often team-based, mobile can play an important role in enhancing team communication and collaboration as well as decision-making efficiency.

A whopping 94 percent of students in a recent survey said they want to use their cell phones in class for academic purposes. The Student Pulse Survey from Top Hat, conducted by independent research firm Survata, polled 520 college students about digital devices, textbooks and learning. Top Hat is the maker of a classroom engagement platform that allows students to use their own devices to participate in discussions and access course content.

Many students said they would be willing to use their phone more often for various class activities, such as check in to the class (60 percent), answer in-class polls (59 percent) and access a professor's slides (54 percent). Just 6 percent of students said they don't want to use their phone in class for academic purposes.

The new phones would use one radio frequency band, 900 MHz, throughout Europe instead of multiple bands. This would allow users to have a signal no matter where they were. The phone design also included features like SMS (texting) and increased security measures.

By 1992, the antennas and phone bodies had both shrunk from the days of the brick phones. The next significant development was the Nokia 1011, the first GSM (2G) phone to be mass-produced, which was introduced in 1992.

Many more years earlier than most people realise saw the debut of the first smartphone. The IBM Simon, which was introduced in 1994, is regarded as the first smartphone in history because it was the first gadget to include apps and a touchscreen.

The Nokia 5110 launched the early 2000s demand for mobile phones with interchangeable cases. People wanted the ability to change the color of their phones, without the need to buy a completely new device.

The first cell phone with a colour screen, the Siemens S10, was introduced in 1998 and was a game-changer. It could show up to six lines of text, however the number of lines that could be shown may be reduced if the font size was increased to make the text easier to read.

In 1999, Samsung released the Samsung SPH-M100 Uproar, a revolutionary phone of their own, not happy to let Motorola and Nokia have all the limelight. It gave the user the option of playing music by fusing the characteristics of a cell phone with an MP3 player. Even a dedicated play/pause button was strategically situated on the phone.

The size and weight of phones has increased at the turn of the millennium. Launched in 2000, the Nokia 3310 not only become one of the most recognisable phones ever, but it is still among the top-selling smartphones today.

It was just what the industry needed. Basic phones were as cheap as they were going to get and with nearly everyone who wanted one having one. Manufacturers and network providers needed a reason for people to go out and buy another mobile phone. Many hoped the Nokia 7650 would be the reason.

The 7650 was actually a smartphone as well. The UI, which provided messaging, WAP internet access, image management, a calendar, to-do lists, and a coloured version of the well-known Nokia Snake game, was powered by the Symbian OS v6.1. 041b061a72
