Mobile phones have become the "partner" in our lives
In addition to daily use
charging issues have always been the focus of everyone's attention
What are the little knowledge about charging mobile phones
?
Today, the editor will take a disk of
mobile phone charging. What are the things that can be done when charging
1
What charging device is used for?
When charging your phone
It is best to choose original charger and charging cable
If the original charging device is damaged
, choose charger and charging cable produced by regular manufacturers
This can reduce the probability of safety hazards
Do not use unbranded inferior charger and charging cable
to prevent damage to the mobile phone battery
2
Fast charging or slow charging?
charging IC ( integrated circuit ) will intelligently adjust the current and voltage when charging
Therefore, fast charging itself is safe
At the same time, fast charging has little impact on mobile phone batteries
When there is conditions or in a hurry to go out,
can you choose fast charging
3
charging environment for mobile phones?
The best working environment for mobile phone lithium battery is 0℃-35℃
Charging in a low-temperature environment
The protection mechanism of mobile phone battery will cause slow charging
Charging in a high-temperature environment
Charging in a high-temperature environment
The battery may be permanently damaged
Recommended to charge in a ventilated and heat-dissipated environment
4
Or plug in the mobile phone first or plug in the power first?
The most scientific method is to charge
, plug in the power supply first and then plug in the mobile phone
, and then pull out the mobile phone first and then pull out the power supply
. If you plug in the mobile phone first and then plug in the power supply
, the voltage pulse will be generated at the moment of charging
. If you pull out the power supply first and then pull out the mobile phone
, it is easy to generate reverse instant current
, affect the service life of the mobile phone
,
, 5
,
, , can you not pull out the charger after charging?
not!
The charger is plugged in the socket for a long time
Although there is no connection to the mobile phone
, the circuit board inside the charger is still in the power-on state
will waste a certain amount of power. Not to mention
It is easy to cause heat
causes internal electronic components to age
or even cause short circuit
greatly shortens the service life of the charger
6
Can you charge your phone with a computer?
The USB interface current of the computer is unstable
will continue to change with the computer's usage intensity and does not match the current of some mobile phones
. This continuously outputs unstable voltage and current
will cause certain damage to the mobile phone circuit
and affect mobile phone data
Use a computer to charge your phone
In addition to the slow charging speed
may also cause fast battery consumption,
battery heat, etc.
, thereby shortening the service life of your phone battery
, so it is best not to charge your phone with a computer
7
What is the most appropriate battery?
The most perfect battery is the state is 65%-75%
But it is a bit difficult to keep it in this range on a daily basis
So try to control the battery to 45%-75%
Many people are used to charging again when the battery is less than 20%
In fact, 20% battery reminder
is a kind of battery self-protection Mechanism
If you continue to use
when the battery is too low for a long time, it will affect the battery life
In addition,
Charging the battery to 100%
will also bring a certain pressure to the battery
8
Can the mobile phone be charged all night?
It is best not to charge your phone all night
The phone will stop charging after full charge
But standby itself will consume part of the battery
causes the phone to charge repeatedly
This way, the battery will suffer a large loss in the past
If you forget to unplug it after full charge
Recommended to choose a socket with overcharge protection
