Digital Lifestyle and Smart Tech Adoption in California
Californians embrace technology in their daily lives at rates that surpass national averages, creating a digitally connected population across the state.
Smartphone usage
Smartphones are central to the digital lives of many Californians. In fact, 81.9% of residents say their smartphone is their main device. This mirrors the national trend where 97% of Americans own cellphones, with smartphone ownership reaching 85%.
Such high adoption represents extraordinary growth since 2011, when smartphone ownership stood at just 35% nationwide.
The average person now spends 4 hours and 37 minutes daily on their smartphone, which is equivalent to nearly one day per week or approximately 70 days annually.
Moreover, users check their devices about 58 times daily, with over half of these checks occurring during work hours. This ongoing use leads to many micro-sessions daily. Data shows that half of all screen time sessions start within 3 minutes of the last one.
Smart home adoption
California homes increasingly feature connected technology, with 50.8% of households now equipped with smart home devices. This places California consistently among the top 5 states nationwide for smart home adoption.
California may not lead the country in home automation, but it is still a strong adopter. Connecticut holds the top spot at 28.2%.
Nationally, smart home technology has grown from approximately 7% of households in 2015 to 22.3% today.
The smart home market, valued at $174 billion globally in 2025, is projected to reach $537.27 billion by 2030.
Entertainment devices, like smart TVs, lead adoption at 72%. Security systems follow at 56%. Smart lighting comes next at 49%, and climate control rounds it out at 39%.

However, only 11.5% of Californians say they have tried these immersive experiences. High device costs, technical limits, and the need for fast internet hold back wider adoption.
At present, 71% of consumers would shop more if they could use AR in their shopping experience.
Looking ahead, industry forecasts predict VR will experience a 21.6% compound annual growth rate from 2020 to 2027. The advertising sector is noticing this potential.
About 67% of agencies say they are using AR technology more.
Challenges remain before mainstream adoption occurs. Many smartphone users can’t fully enjoy AR/VR. This is because of low visual quality and a narrow focal view.
Also, the best AR/VR experiences need 5G connectivity. This technology is still growing in California.
Cybersecurity and Privacy Concerns in a Connected State
Privacy and security concerns grow rapidly as California’s connected devices proliferate.
Smart technology is growing fast. This brings new risks for consumers and businesses. They must work together to tackle these challenges.
Online privacy importance
Everyday devices are gathering more personal data. Californians are worried about their privacy.
Currently, 70% of consumers rate online privacy as “extremely important” in their digital lives. These concerns prompted California to introduce groundbreaking legislation protecting consumer data.
The California Consumer Privacy Act (CCPA) stands as a landmark privacy law giving residents unprecedented control over their personal information.
This law lets you find out what personal data companies collect. You can also ask them to delete it.
Concurrently, the California Privacy Protection Agency (CPPA) recently announced final rules requiring privacy risk assessments, cybersecurity audits, and guardrails around automated decision-making technology.
For businesses operating in California, these regulations establish clear obligations. Companies that could significantly risk consumers’ privacy must write risk assessments before high-risk data processing.
Businesses that handle sensitive data must conduct independent cybersecurity audits every year. These audits should be based on solid evidence, not just statements.
California also passed the first state law requiring manufacturers of Internet-connected devices to equip products with reasonable security features.
This legislation specifically mandates unique passwords for each device or forces users to change default passwords before using them.
