Some individuals are embracing ‘tech-nostalgia’ by opting for simpler devices, such as ‘dumbphones’ or flip phones, to combat the overstimulation and constant notifications associated with advanced smartphones. Beyond device choice, smartphone usage is reshaping communication and cognitive habits. A phenomenon known as ‘callergy’ has emerged, characterized by an aversion to phone calls among Millennials and Generation Z. Research indicates that 70% of users aged 18 to 30 keep their phones on silent permanently, preferring text or voice messages to maintain control over information flow. Experts also note that smartphones impact cognitive performance. Even when not actively in use, the presence of a device can consume mental resources as users resist the urge to check it. Studies suggest that cognitive performance on complex tasks improves when devices are kept in a different room. ## Timeline ### 2026-09-07: Smartphone usage trends show rising call avoidance and cognitive distraction Generation Z is increasingly avoiding phone calls due to ‘callergy,’ while the mere presence of smartphones is shown to reduce cognitive focus and concentration. 2 sources. https://clstr.news/cluster/smartphone-usage-trends-show-rising-call-avoidance-and-cognitive-distraction ### 2026-08-11: Digital fatigue drives rise in tech-nostalgia and dumbphone use Younger generations are increasingly adopting ‘dumbphones’ and flip phones to combat digital fatigue and overstimulation caused by constant smartphone connectivity and social media. 3 sources. https://clstr.news/cluster/digital-fatigue-drives-rise-in-tech-nostalgia-and-dumbphone-use --- Cite as: Smartphone usage and digital fatigue trends.
