Powerful Smartphone: These 5 smartphones will get rid of the problem of frequent charging,
Charging your phone when it loses 10 percent of its charge would be the best-case scenario, according to Battery University. Obviously, that's not practical for most people, so just plug in your smartphone whenever you can. It's fine to plug and unplug it multiple times a day.
There are few strands of consumer technology more stuffed with jargon and nonsense than in smartphones. Manufacturers love to wax lyrical about how great their processors are or talk about the aperture of their cameras. All that’s great if you’re a tech expert, but for the average user, it tends to sound lik

Still, don’t mistake that minor critique for condemnation, these are still enviable phones and, for my money, far better than the recent Samsung and Apple offerings. The king of flagship killing phones is alive and well.

I confess I scoffed when I first heard the rumours about the Pixel 3A. “If it’s got similar specs to the Pixel 3 and Google release it for under £500, it will immediately become my top pick,” I said to a colleague, not expecting to have to revisit this article with any urgency. And then Google went ahead and did just that. They even sliced another hundred quid from what I predicted, releasing the product for just £399. That's scandalously cheap for what you get.

It's the first time I haven't fallen head over heels for a Google smartphone. The camera is, predictably, incredible. The new 90Hz display is just as gorgeous as it was on the OnePlus devices. There are lots of fun new features, like the live caption which can add English language captions to any song or video you might be playing. But overall, it just feels a bit uninspiring.
IntroductionAs portable media devices, such as smartphones, have become an increasingly pervasive part of our lives, they have also become increasingly capable of supplementing, or even supplanting, various mental functions. With the capacity to be used as phonebooks, appointment calendars, internet portals, tip calculators, maps, gaming devices, and much more, smartphones seem capable of performing an almost limitless range of cognitive activities for us, and of satisfying many of our affective urges. However, sensationalist articles with titles such as, “Are Smartphones Making Us Dumber?” (Ellison, 2012) and, “Is Your Smartphone Making You Fat and Lazy?” (Morin, 2013) encourage the conclusion that reliance on smartphones and related technologies is not aiding mental functioning, but rather, is having a negative impact on our ability to think, remember, pay attention, and regulate emotion. Some have even made the claim that modern connectedness is “rewiring our brains” to constantly crave instant gratification, and that this threat to our society is “almost as important as climate change” (Greenfield, 2013). Are these simply examples of an older generation once again thinking its “progeny yet more corrupt?” (Horace, 20BC) or is there some evidential legitimacy to these fears?For all the media attention that this subject garners, the supporting scientific literature is still in its nascent stages. The present paper aims to consolidate and integrate some of the key empirical evidence that has emerged regarding the association between smartphone technology and cognitive and affective functioning. We examine the extant corpus of studies in terms of the specific claims put forth by the researchers who conducted them, and where relevant, offer a consideration of factors that might qualify or limit the generalizability of the findings. As we proceed, we evaluate the domains in which there is reason to be concerned about the growing presence of smart technology in our culture, domains in which smartphone technology may enhance cognitive skills, and domains in which the scientific literature is not mature enough to substantiate such claims. In this discussion, we examine evidence relating to both the acute consequences of media technology use on the performance of ongoing cognitive tasks, as well as the more lasting relationships that may exist between technology usage habits and cognitive abilities. As a snapshot of the current literature related to this topic, we also hope this paper can serve as a resource for those conducting further research in this area.Challenges and Limitations in ScopeThe 21st century has already provided us with a vast array of technological advances that markedly shape the ways by which we interact with the world. In this paper we could not hope to investigate every type of emerging technology, nor would we endeavor to review every psychological implication of the technologies in question. For instance, much has already been written about the impact of violent television and video games on children (Hartmann et al., 2014), and this is one of many topics that fall outside of the scope of the present review. Likewise, this review will not venture into the growing body of research exploring problematic usage of mobile phones and the addiction-like symptoms of overuse (Bianchi and Phillips, 2005; Billieux et al., 2008; Kwon et al., 2013; Lee et al., 2014). Nor will it consider studies exploring the possible effects of radio frequency electromagnetic fields emitted from cellular devices on the human brain and its functioning (Zubko et al., 2016). There is also a growing body of work exploring how technology-related habits may be affecting the development of individuals’ social competencies and emotion reading, and this is yet another topic that has been tackled elsewhere (Brown, 2014; Misra et al., 2014; Uhls et al., 2014; George and Odgers, 2015; Mills, 2016) and to which we give little consideration.To give the present review some focus, we begin with the premise that smartphones are an especially impactful technological development, due to their flexibility of function, portability, and increasing proliferation. Accordingly, we limit the scope of our examination to work that is directly relevant to smartphone-related impacts. Moreover, rather than concentrating on “problem” behavior related to smartphone technology (see e.g., Bianchi and Phillips, 2005; Hadlington, 2015), we mainly explore evidence regarding the consequences of typical everyday smartphone use. Finally, while a wide array of mental functions might be influenced by smartphone habits, we home in on the impacts in the three domains that are most widely discussed in the lay media and that have garnered some consideration in empirical work: attention, memory, and delay of gratification (reward processing). We then give brief consideration to some emerging work exploring links between smartphone habits, executive functioning, and academic performance.Some representative studies exploring the relationship between smartphone (and related) habits and cognitive functioning are summarized in Table Table11. Researchers interested in this area of study are faced with many difficulties when developing an empirical approach, and these challenges necessarily pervade our attempt to review the extant literature. To begin, smartphones have become so ubiquitous that it is nearly impossible to employ true experimental methods with random assignment into different technology exposure/access groups. Even when it is possible to find technology-naïve participants, contrasting them with experienced technology users is likely to be a confounded approach, due to disparities in SES, age, resources, and social expectations among groups who differ in their habits. As a result, much of the literature consists of quasi-experimental and correlational studies, from which strong inferences regarding causality cannot be drawn. The few truly experimental studies that have been performed on this topic typically investigate only momentary effects of smartphone use or deprivation on cognition, rather than long-term impacts.Table 1Representative publications exploring associations between technology usage and cognitive domains.ReferenceFinding summaryAttentionAlzahabi and Becker, 2013Frequent media multitaskers are better at task switching; No correlation with dual-task performanceCain and Mitroff, 2011Effect of media multitasking on distractor filtering is due to differences in attentional scope rather than working memory capacityLeiva et al., 2012Within-phone interruptions cause up to a 4x delay in completion of a primary taskLui and Wong, 2012Frequent media multitaskers exhibit better multisensory integrationMoisala et al., 2016In the presence of distractor stimuli during a sustained attention task, frequent media multitaskers perform worse and exhibit more right prefrontal activityOphir et al., 2009Frequent media multitaskers perform worse on a task-switching paradigm, due to reduced ability to filter out interferenceRalph et al., 2013Frequent media multitaskers report higher levels of everyday attention failures; No relationship between media multitasking habits and memory failures, attention switching, or distractibilityRalph et al., 2015No relationship between habitual media multitasking and sustained-attention processesStothart et al., 2015In an attention-demanding task, mobile phone notifications cause a disruption in performance similar in magnitude to active phone usageThornton et al., 2014The “mere presence” of a cell phone may produce diminished attention and worsened task-performance, especially for tasks with high cognitive demandsYap and Lim, 2013Frequent media multitaskers exhibit split visual focal attention, whereas infrequent media multitaskers exhibit unitary visual focal attentionMemory and knowledgeBoari et al., 2012Forcing users to perform mental rotations, rather than automating them, enhances spatial knowledge acquisitionBurnett and Lee, 2005Navigation system use impairs cognitive map buildingCain et al., 2016More frequent media multitasking correlates with poorer working memory performance and lower standardized test scoresFrein et al., 2013Frequent Facebook users exhibit poorer performance on a free recall taskHenkel, 2013Taking a digital photograph reduces recall accuracy for details of specific images; This effect is mitigated by zooming in on the objectParush et al., 2007The use of navigation systems produces spatial knowledge impairments, but these can be mitigated by requiring users to request their positionSmall et al., 2009Older adults with significant internet experience show increased fMRI activity during internet search relative to those who are ‘net naïve’Sparrow et al., 2011When people assume that they have future access to information, they exhibit lower rates of recall for that information, but remember where that information can be accessedUncapher et al., 2015Frequent media multitaskers exhibit poorer working-memory performance and increased attentional impulsivityXavier et al., 2014Internet/Email use predicts better performance on a delayed recall task in the elderlyDelay of gratification and rewardHadar et al., 2015Administering smartphones to a smartphone-naïve sample results in greater delay discounting and decreased information-processing abilitySanbonmatsu et al., 2013Frequent media multitaskers report greater impulsivity and sensation seeking along with poorer working memory performanceWang and Tchernev, 2012Cognitive needs are not satisfied by media multitasking; Emotional gratifications are obtained despite not being soughtWilmer and Chein, 2016Greater investment in mobile devices correlates with weaker tendency to delay gratification.

Indeed, the limited evidence we have regarding the compatibility between subjective and objective usage measures indicates that self-report estimates of usage are likely to be of limited reliability, and only modestly correlated (if at all) with actual usage (Andrews et al., 2015). Further, because the landscape of technology usage opportunities is ever-evolving, many of the questionnaires that researchers develop turn out to have a limited “half life,” sometimes becoming dated (or obsolete) before they can be applied more broadly across research labs, or used to establish meaningful longitudinal trends in key behaviors (Roberts et al., 2005; Rideout et al., 2010). Relatedly, the fact that smartphones are a relatively recent development precludes the existence of any broadly generalizable longitudinal evidence. Thus, even when connections between technology and cognition are established, we do not know the extent to which these impacts are lasting. Another crucial challenge is that it can be difficult to assess technology usage habits without intruding on participants’ natural behavior. Attempts to assess smartphone-related habits (questionnaires, diaries, etc.) can draw the participants’ attention to their patterns of use, which could alter their naturalistic behaviors and affect the way in which participants approach laboratory tasks that are meant to assess the cognitive impacts of such habits. In spite of these many challenges, some foundational research has been conducted, and some intriguing patterns are beginning to emerge. In the following sections, we discuss recent research in the areas of attention, memory and knowledge, delay of gratification, and conclude with a consideration of studies investigating more general effects on academic performance and other domains.
