Nowadays, mobile phones have become an indispensable item in our lives, but when your mobile phone has passed the replacement period, it is still idle in the corner. Have you ever thought about how to use its waste heat? The following are some methods I have proposed, which I hope will help you.

First, install security software.

Even if you no longer use your old mobile phone, it still has intelligent functions, such as Wi-Fi, Bluetooth, GPS and so on. You can download security software and turn it into a security camera to help you protect your home. When you are not at home, it can automatically take and push photos or videos to remind you that someone has entered the home.

Second, become a children's toy.

Children like to treat everything as their own toys, and outdated mobile phones can also be one of their toys. You can download some apps or games suitable for children to use for study or entertainment.

Third, it is used as a music player.

If you have the habit of listening to music or collecting movies, your old mobile phone can become a music player. You can download some music apps or collect music songs, connect Bluetooth headsets and listen to your favorite music anytime, anywhere. If you often take the bus or fly, you can download some movies or TV plays on your mobile phone to kill boring time.

Fourth, be a wireless router.

The old mobile phone is equipped with Wi-Fi hotspot function. With this function, you can turn it into a small wireless router to provide wireless network connection for other devices. This will be very useful in traveling and camping, because you can connect your mobile phone to the 4G network, and then enjoy the wireless network connection through this mobile phone.

V. Inquiries about the library

You can turn it into a small library inquiry computer. Using the free book application, you can query the books that can be borrowed at present, reserve books and so on. This is very suitable for people who love reading.

Sixth, as GPS navigation.

The GPS function of the old mobile phone can help you guide the way when driving or hiking. You can download some GPS navigation apps and fix them on your car or bike, so that you can easily find your destination.

Seven, help you take high-quality photos.

Although the camera of the old mobile phone is not as good as the current mobile phone, there is still a lot of room for improvement in photo quality. You can install some camera applications or editing applications to capture moments or add special effects.

These are some of the ways I put forward to use old mobile phones. Through these methods, you can make full use of the waste heat of the old mobile phone, expand its use range and bring convenience to your life.
