Does the wireless charger damage the phone? What should I pay attention to when using a wireless charger? Posted by benzoenergy.com
The use of chargers allows many electronic devices to operate normally. Without chargers, our lives will be troubled to a certain extent. In order to enhance everyone's understanding of the charger, this article will introduce the wireless charger related content, mainly to analyze whether the wireless charger is harmful to the mobile phone and explain the precautions of the wireless charger. If you are interested in chargers, you might as well continue reading.
Is the wireless charger harmful to mobile phones?
The
wireless charger will not harm the mobile phone under normal
circumstances. The current working frequency of wireless charging is
below 1M, so it will not affect the signal of the mobile phone. Wireless
charging has no effect on the battery life of mobile phones. It is
basically the same as wired charging, but the rate is lower, but the
conversion rate of wireless chargers is still very high, which saves
more energy. Wireless chargers mainly use inductive coupling technology.
Because the coupling technology mainly generates current through the
magnetic field of the coil, the internal components of the battery
cannot form a magnetic field, so the internal structure of the battery
will not be damaged during the power-on process. At present, most mobile
phones on the market conform to the QI wireless charging standard, with
a built-in wireless receiver, which has a rated voltage and current, so
the wireless charger has no effect on the mobile phone.
Precautions for using wireless charger
1). Please choose the original or 3C certified product for the charging plug
As
an electrical product, it is recommended to use the original plug.
First, because it is specially developed for your mobile phone, the
charging speed is guaranteed. Second, the safety is guaranteed. In
addition, other 3C products with the same parameters as the original
plug can also be used with confidence. 3C certified products have
requirements for safety from design to production, and safety is
guaranteed. Because the use of inferior chargers can cause explosions
and hurt people, there are too many things to mention, so I won't say
more here.
2). Is the charging cable correct?
The
same is true for the charging cable. It is best to use the original
charging cable. The core material in the charging cable, the diameter of
the wire, and the material of the metal contact piece of the charging
interface will all determine the amount of current that can be carried.
After anatomy, the diameter of the inferior charging cable is obviously
smaller than the national standard value, and there is no insulating
protective film inside. If you choose a low-quality charging cable,
firstly, the insulation performance is poor, the current carried is
small, and the charging speed will slow down, which will seriously
damage the battery, and even cause electric shock, fire and other
accidents.
3). It should not take too long for the first charge
The
first charge does not require anything to be fully charged for 12
hours. This is what the old battery needs to do. The current battery is
basically a lithium battery or a polymer lithium battery. The first charge only needs to be charged as usual.
4). Number of charging
There
is a saying: each mobile phone battery has a fixed number of recharges.
If the number of recharges is too many, it will accelerate the aging
and strain of the battery! In fact, this is wrong. The number of
recharges of a lithium battery refers to the complete charge and
discharge, so it is best to charge as you use it.
5). New mobile phones need to be activated?
The
new mobile phone needs to use up all the electricity in the mobile
phone before charging, and it needs to be operated repeatedly 3-4 times.
This is called activation. This is required for mobile phones in the
past, but now lithium batteries are no longer needed.
6). Play while charging
According
to technical standards and corporate regulations, the mobile phone
should be safe when used in conjunction with the wireless charger. Under
normal circumstances, there is no problem in making and receiving calls
when charging. However, the market is flooded with many low-quality
chargers. Such chargers cannot meet safety requirements and are prone to
dangers such as soft breakdown. Therefore, users are reminded not to
buy too cheap chargers. It is best to buy 3C certified chargers and look
for charging. The safety mark 3C on the device. Therefore, when using
Sanwu products, you need to be vigilant while charging and playing with
your mobile phone. Inferior chargers are easy to die, and if unexpected
problems occur, they may be fatal!
7). Overcharge
In
the battery safety test experiment, it will continue to charge for 7
hours when fully charged, and the output voltage will increase to 1.06
times of the standard voltage. In addition, the battery itself has a
protection circuit, so it will not cause danger and will not explode.
But if you use inferior batteries, it's hard to tell. The explosion of
Samsung's mobile phone illustrates this point. Therefore, it is best to
unplug the charger in time after fully charged.
8). Do not wear a mobile phone case for charging
In
order to protect the mobile phones that we can't do without, many
people choose to wear mobile phone covers! But everyone doesn't know
that lithium batteries are very heat-resistant and will generate heat when charging, so it is best to take off the phone case and charge.
