The mobile phone can now be said to take all of our eating, drinking, socializing, shopping, gaming, payment… it is inseparable from it. For everyone, the battery of the mobile phone will never be enough. In fact, there are many misunderstandings about the mobile phone charging, such as the mobile phone charging Should I unplug the power?

First of all, the charger will consume a certain amount of current if it is not unplugged, and the charger will continue to heat when it is placed on the power strip for a long time, which will accelerate the aging of the equipment and easily cause a short circuit, which may cause a fire hazard.

When charging, should I plug in the phone or the power first?
If you use non-original chargers and ordinary power strips for charging, if you plug in the phone first and then plug in the power source, a relatively large voltage pulse will be generated at the moment of charging, which may cause harm to the phone.

Similarly, after using a non-original charger to fully charge, first unplug the power supply will easily produce reverse instantaneous current, at this time, if you do not unplug the phone first, it may also damage the phone.

Of course, if you use the original charger to charge, the steps of plugging first and unplugging first have little effect on the phone. However, it is best to develop a good habit: when charging, first plug in the power and then plug in the phone; when it is full, unplug the phone first and then unplug the power. This is a good habit.

There are coups to save power on mobile phones-reduce screen brightness
The screen brightness is one of the most power-hungry places. When the battery of the mobile phone is low, the brightness can be appropriately reduced to have a longer battery life.

Power-hungry functions can be turned off when not needed

The seemingly small functions of mobile phone positioning, Bluetooth, and WIFI consume a lot of power. They can be turned off when not in use, and turned on when in use.

Turn on low battery mode

The functions of mobile phones nowadays are more user-friendly, and all have low battery mode. Just set-Battery-Low battery mode on to save power.

What is the use of the phone’s airplane mode?

/Reset network/

The cell phone signal is bad, there is no network, the first time you shut down and restart? In fact, you only need to turn on the airplane mode, wait for 1 to 2 seconds, and then turn off the airplane mode. At this time, the mobile phone will search the network again, which saves time and effort than turning on and off the phone.

/Don’t Disturb Online at ease/

Want to play games with peace of mind and don’t want to be disturbed by various phone calls? Turn on the airplane mode and you can still go online! Although all networks will be automatically disconnected when the airplane mode is turned on, you only need to restart the wifi manually.

/Prevent bear children from pressing randomly/

Some parents will let their children use their mobile phones as toys. In order to prevent the babies from pressing and sending wrong messages, they can set the mobile phone to flight mode first.

These rumors are not credible
/When the battery power is low, the radiation is 1000 times normal/

The mobile phone does have radiation, but the strength of the mobile phone’s radiation is only related to the strength of the mobile phone’s signal, and has almost nothing to do with the power of the mobile phone.

Radiation is everywhere in our lives, from the sun to the cell phone. It can be said that the possibility of staying away from radiation is zero. The radiation generated by the mobile phone we use is actually called “non-ionizing radiation”, and its energy is extremely small.

So if the battery is low, just worry about turning off suddenly~

/Mobile phone will degauss bank card/

The data interaction generated by mobile phones mainly relies on electromagnetic waves. The frequencies of electromagnetic waves emitted by mobile phones range from 850MHz in the UHF band to 2.4GHz in the microwave band. In this interval, electromagnetics mainly exist in the form of electric fields, not magnetic fields, so they will not have any effect on the magnetic stripe bank card.

If you have ever had a mobile phone and a bank card being demagnetized together, it may be because you have accidentally encountered some strong magnetic material, otherwise it will generally not be demagnetized.

/You can call for help even if your mobile phone has no signal/

If the mobile phone has no signal, it cannot establish a communication link with the mobile communication network. Any emergency calls made at this time are invalid. In fact, the legendary call in distress means that an emergency call can be made when there is no SIM card or when the phone is out of service. But if the communication between the mobile phone and the base station is interrupted, it is impossible to make a rescue call.
