Now days, the smartphones which are coming are small in size and light in weight which makes it very easy to carry them. You don’t need to sit beside the receiver as your mobile phone is not attached with anything.
Entertainment-
Mobile phones have become a source of unlimited entertainment. The things which we never thought would be present in a mobile phone are now possible. Smartphones have come into existence which not only help you in making calls but also help you to stay entertained by allowing you to play games, listen to music and do lots of other stuff.
Negative impact of cell phones-
Bad impact on studies
It is true that mobile phones can help students in studies but only if they use them wisely. Most of the students become additive to mobile phones and are found playing games, chatting with their friends and watching movies and other stuff. If students are busy keeping their eyes on their mobile phones at all times they won’t get time for studying which would lead to poor grades.
Heath issues and accidents
Mobile phones lead to a lot of accidents. A lot of people do their daily work, drive while taking on mobile phones. There is high risk of accident if you are talking on the mobile phone and driving as you are giving your half attention to the mobile call and are having half attention on the road.
Conclusion
These were the advantages and disadvantages of mobile phones. In the end, it all depends on our usage. Cell phones are the most personal device to us and we should make an optimal use of them.
