“Airplane mode” is often overlooked, but it has a significant effect. Do you know these four uses?

Everyone has a smartphone, and usually when you're on an airplane, you need to turn it on to ensure that the plane isn't disturbed by signals from the phone during the flight, which could interfere with the aircraft's instruments.

This is also the original purpose of "Airplane Mode", and everyone knows this function. However, few people know the other uses of "Airplane Mode".

In fact, we can use it most of the time in our daily lives. Here are 4 wonderful uses of airplane mode, each of which is super practical!

1. Emergency power saving

When you are out and about, the more you use your phone, the lower its battery will be. Some phones that are not optimized (for example, apps that start automatically when the phone is turned on run in the background, app notifications that pop up frequently) will also lose battery quickly when not in use.

You are planning to go home, but you see that the battery level is only around 10%. Of course, you don’t need to rent a power bank. What should you do?

You can turn on "Airplane Mode" to save power!

After turning it on, all external data, WiFi, GPS, etc. of the mobile phone will be turned off, and background operations will also be turned off, which can save at least half of the power.

2. Search Signal

When the mobile phone signal or network is poor, ordinary users will generally restart their phones and let the phone automatically search for network information again.

In fact, there is no need to be so troublesome. Turning on the airplane mode and waiting for a few seconds before turning it off has the same effect and saves more time!

Moreover, you may not be able to connect to the Internet after paying the overdue mobile phone bill. We can use the same method to solve this problem.

3. Anti-interference, alarm clock works normally

For example, some friends who are light sleepers don’t like to be disturbed by various messages or phone calls while sleeping, so they will turn on the airplane mode. They don’t have to worry about oversleeping, because after turning on the airplane mode, the mobile phone alarm can still be used normally.

4. Anti-roaming charges

If you forget to apply for a roaming package or do not purchase a local data card when traveling, it is recommended to turn on the airplane mode before connecting to the hotel's Wi-Fi to avoid roaming charges due to being out of town!

In addition to the above-mentioned uses, if you don’t want your children to play with mobile phones too much, you can also turn it on.

After it is turned on, the network function is turned off, but you can still continue to use non-network applications, such as watching downloaded movies, listening to cached music, playing games that do not require an Internet connection, etc.

It can also prevent misunderstandings and embarrassment such as making wrong calls or sending wrong messages.

This mobile phone function may seem insignificant, but it has such a great effect. So, in addition to the ones introduced above, do you know other uses?
