How to Break up With Your Phone: The 30-Day Plan to Take Back Your Life

Health and science journalist Catherine Price opens this revised edition of her 2018 self-help guide by observing that the situation she first wrote about has only worsened. More than half of Americans now report feeling "addicted" to their smartphones, the average person spends four and a half hours a day on their phone, and developments in artificial intelligence, deep fakes, and algorithmic manipulation have made technology more pervasive and invasive. At the same time, she notes signs of progress: advocacy groups, legislation such as the European Union's General Data Protection Regulation (GDPR, a set of strict data-privacy rules), advisories from the U.S. surgeon general, school smartphone bans, and members of Gen Z voluntarily reducing their own screen time. Price frames the book's central premise at the outset: "Breaking up" with one's phone does not mean abandoning it but rather creating a healthier, more intentional relationship with it.

Price describes how smartphones entered people's lives so quickly that most users never paused to evaluate how they wanted to interact with them. She includes a modified version of the Smartphone Compulsion Test, developed by Dr. David Greenfield of the Center for Internet and Technology Addiction, and notes that most people score high enough to warrant professional evaluation. She recounts her own turning point: one night while feeding her infant daughter, she realized her baby was staring up at her while she was staring down at her phone. This moment prompted her to investigate the effects of smartphone use on attention, memory, and mental health. She and her husband experimented with a 24-hour "Digital Sabbath," a complete break from all screens, and found the experience so restorative that it motivated her to seek a more balanced long-term relationship with her phone. Price recruited nearly 150 volunteers across six countries and 15 American states to test a breakup program she designed, drawing on research in mindfulness, habits, behavioral addictions, neuroplasticity, and product design. The book is structured in two parts: Part I ("The Wake-Up") presents the evidence for why phones are harmful, and Part II ("The Breakup") provides a 30-day guided plan.

Part I argues that smartphones and apps are deliberately engineered to maximize user engagement. Price quotes former Google product manager Tristan Harris and former Facebook (now Meta) president Sean Parker, both of whom confirm that apps are built to consume as much user time and attention as possible. She notes that tech insiders, including Steve Jobs, Bill Gates, and former Facebook executive Chamath Palihapitiya, restricted their own children's access to the products they helped create, suggesting they recognize risks they do not publicize. Price defines addiction as continuing to seek something despite negative consequences and argues that many people's relationships with their phones meet this definition.

Price explains how dopamine, a brain chemical that trains people to associate actions with rewards, drives compulsive phone use. Once the brain links checking a phone with receiving a reward such as a text or "like," dopamine is released upon encountering the phone, often before the user consciously decides to pick it up. She catalogues the psychological vulnerabilities app designers exploit: constant novelty ensures a steady stream of dopamine; unpredictable rewards, what psychologists call intermittent reinforcement, are more compelling than consistent ones, making smartphones function like slot machines; FOMO (fear of missing out) creates a self-reinforcing cycle of anxious checking; and social media platforms exploit the human need for validation. Price argues that many people reach for their phones to numb emotional pain, but this short-term relief does not address the underlying cause.

Price devotes her longest chapter to social media, calling it the most problematic app category. Users are the product, not the customer, and advertisers pay for engagement. Feeds are designed without stopping cues to keep users scrolling indefinitely. Price contends that social media contributes to loneliness because hours spent online replace hours available for in-person relationships. She presents alarming data on teenagers: 40 percent of high school students reported persistent sadness and hopelessness in 2023, up from 28 percent in 2011, and one in five reported seriously considering suicide. She cites social psychologist Jean Twenge's argument that trend lines in teenage well-being shifted dramatically after the iPhone's 2007 introduction, and notes that surgeon general Vivek Murthy has called for Congress to mandate warning labels on social media platforms. Price also catalogs social media's surveillance capabilities and its role in spreading misinformation and deepening societal polarization.

Price examines how phones reshape the brain through neuroplasticity, the brain's ability to physically change in response to experience. She argues that smartphones erode attention spans by keeping users in continuous partial distraction. Attention researcher Gloria Mark found that the average time people stay focused on any screen before switching dropped from about two and a half minutes in 2004 to roughly 47 seconds. Price debunks multitasking, citing a Stanford study showing that heavy multitaskers performed worse at filtering irrelevant information yet believed they excelled. She details how phones interfere with memory by blocking experiences from being encoded, overloading short-term memory, and disrupting long-term memory formation. Weakened memory, she argues, impoverishes schemas, the networks of connected memories that enable creativity and insight. Price also explains that screen light suppresses melatonin, a sleep-regulating hormone, and that phones prevent "flow," a state of complete active engagement described by psychologist Mihaly Csikszentmihalyi. She distinguishes between "True Fun," the confluence of playfulness, connection, and flow, and "Fake Fun," activities that feel engaging but leave users feeling empty.

Price argues that algorithms are increasingly shaping users' decisions and identities without their awareness, calculating that humanity collectively spends more than 1.3 million years' worth of attention on social media every single day. She transitions to the solution by introducing mindfulness, the practice of paying deliberate attention to present experience without judgment, and cites psychiatrist Judson Brewer's randomized controlled trial showing that mindfulness training helped smokers quit at twice the rate of a standard program. She explains the concept of mental "invitations," the impulses the mind constantly generates, and argues that recognizing these as invitations rather than commands gives people the power to choose their responses.

Part II presents the 30-day breakup plan in four weeks. Week 1 ("Technology Triage") establishes a baseline: readers compare actual phone usage with how they want to spend their time, write a breakup letter to their phone, observe when and why they reach for it, practice the WWW exercise (asking "What For? Why Now? What Else?" before each pickup), brainstorm offline activities, and delete their most problematic apps. Week 2 ("Changing Your Habits") modifies environments and devices. Readers turn off most notifications, make their phones visually boring by switching to black-and-white screens and redesigning home screens, move their charging station out of the bedroom, install app-blockers, establish No-Phone Zones and phone bedtimes, and stop phubbing (snubbing companions by looking at a phone). Week 3 ("Reclaiming Your Brain") rebuilds attention through mindfulness exercises, deliberate stillness, reading in print, and meditation, culminating in a 24-hour Trial Separation during which readers turn their phones completely off. Price introduces JOMO (joy of missing out) as a reframing of FOMO: Instead of worrying about missing online events, readers focus on relief from stressful content and redirect attention toward real-life experiences. Week 4 ("Your New Relationship") locks in changes. Readers reflect on the Trial Separation, establish regular "phasts" (phone fasts), clean up the rest of their digital lives, consider making the Trial Separation a recurring Digital Sabbath, and write seven guiding statements covering routines, boundaries, breaks, self-compassion, and offline activities.

In the epilogue, Price reflects on the decade since her own breakup. She still uses her phone as a tool but remains vigilant, modeling intentional habits for her daughter. She calls for individual habit change, societal conversations about technology's role, and legislation to hold tech companies accountable. The book closes with its guiding question: "This is your life: What do you want to pay attention to?" (204).
