The quality of sleep drops if there is a smartphone near the bed.

Tech Like This published a review of 20 scientific studies on the effect of electronic devices on a sleeping person. It turned out that when a smartphone is next to the bed, the quality of sleep drops. Even if the phone is not being used. Next to the phone, a person sleeps less and not so deeply. During the day, he feels sleepy, his productivity drops. If you remove your smartphone from the bedroom for a month, the quality of sleep will improve. If you also limit the use of the gadget before bedtime for this period, many other processes will return to normal: for example, working memory or the ability to experience positive emotions.
