are fewer outlets, such as at airports, it is not uncommon for people to use
this method for emergencies. However, it seems that the phone is consuming
power faster than it would be after charging it with a charger. Then someone
will wonder if it’s really safe tocharge the phone with a computer? So what is the cause of this
phenomenon?
Is it really safe to charge your phone
with a computer?
is that whether you charge your phone with a charger or a computer, you charge
your phone with the same USB cable. The charging mode is different only in
terms of charging current. The difference between regular charger and computer
is only reflected in the speed of charging.
computer USB jack voltage is lower than the charger voltage. In addition, as
the computer power consumption is unstable, the current and voltage will be
unstable. This will cause the cell phone electric ion damage, shorten the life of thecell phone’s battery. With such as the electricity used in watching
movies on the computer is different from when it is on standby.
reason is that using a computer for long periods of time to charge a mobile
phone can have an impact on the activity of lithium batteries.
Because most cell phones now have lithium batteries, there is a certain demand
for charging voltage. High voltage and high current can keep the lithium
battery fully active, while the USB port on the computer provides 5V/0.5A
current. So try charging your phone with a charger.
with a computer is that our mobile phone is not fully charged. In other words,
while our smartphones show 100 percent power, it’s actually virtual power. In
fact, it has something to do with the whole process of charging a cell phone’s
battery. The whole process of mobile phone charging includes three stages:
rapid charging, continuous charging, and trickle charging. After the first two
stages, even though the system’s battery power shows 100%, the battery does not
reach the actual saturation state. At this point, it needs to be charged by a
trickle to be fully charged.
What is trickle charging?
fully, the loss of self-discharge is about 5% of the nominal capacity. At this
time, the computer charges the phone with a trickle charging to make up for the
loss of self-discharge.
of the time, when we see the display of 100% battery power, we think the
charging is complete. In fact, your phone is still using trickle-up charging.
While the phone displays 100% power, the actual power may be 95% or less, which
is why you feel that charging with computer USB is more power consuming.
another 30 minutes or so. One is to make the phone’s battery more powerful. The
other is to protect the elements in the battery and make it last longer.
