I have an idle old mobile phone. The mobile phone I am using now was bought when I was a freshman, and then the old mobile phone that was idle was a bad one used by my father, but the screen was broken and the function was ok. My usage is as follows.
First, it can expand the memory of the mobile phone.
The memory of these two phones is 64 G, and everyone knows that video will be useless under 64 G software. Mobile phones often run out of memory, so clean them up as soon as possible. Then the idle mobile phone can put some downloaded videos, which can reduce the occupation of the video of the mobile phone being used. You can also use the idle mobile phone during PPT class, so that the mobile phone you usually use can be used and studied daily.
Second, separate work from pleasure.
As all college students know, it is the biggest sin to bring your mobile phone with you every time you go to the library to study. They will use them for all kinds of entertainment. When they are tired of studying, they will play with their mobile phones for a while and time will pass. At this time, if you have another mobile phone, you can put the entertainment software on a mobile phone and the learning software on a mobile phone. As long as you control not to bring entertainment mobile phones, you can reduce a lot of time playing mobile phones.
Third, college students can use it to brush online classes.
I'm a junior, and every semester, my school takes a general course, which is called an online course. But there are too many online classes, so let's try our best to use our spare time, that is, spare time to brush online classes. At this time, the occupied mobile phone can't bring us happiness. When we have two mobile phones, one for surfing lessons and the other for entertainment, perfect!
To sum up, idle mobile phones can really do a lot of things. The above is how I use my idle mobile phone.
