- Reset the network. This is the most common way people fly. When she is on the subway, there is often a sudden lack of signal, the record she is browsing cannot be refreshed, and wechat cannot be sent out. She usually starts people straight into airplane mode, with a steady signal when the mobile operator shuts down and restarts.
- Reduce radiation. In fact, as we all know, mobile phone radiation is very serious, but many people have not formed the habit of sleeping mobile phone off. There's a scientific reason why people get dumber after long-term exposure. So what should be done? If you don't turn your phone off at night, remember to turn it on airplane mode so your phone can minimize radiation and put it under your pillow without worrying about radiation.
- Save electricity. Anyway, many people forget to charge their batteries sometimes. Sometimes on the road still far from home, and there is no power bank. At this point, it's very desperate. You want to use your phone to pass the time, and you want to make sure the battery lasts until you get home. In this case, all you need to do is find a good movie on your phone and turn on airplane mode, so you can kill time while enjoying the movie and go home with peace of mind. So why does the battery last so long when airplane mode is on? Since most of the phone's power is consumed by the signal, the airplane mode is turned on, and the power can be saved by more than half.
- Prevent roaming charges. Every time I go out, I lose data on my phone for no reason. I was really surprised when I received an alert that mobile traffic exceeded 20 yuan this month. Then "flight mode" is very important, especially when traveling, if you do not change the roaming package or buy a local data plan, you can directly turn on the flight mode and connect to the wireless network (Wi-Fi) when you arrive at the hotel, thereby subtly avoiding the roaming costs incurred when you are abroad!
