Is It Really Safe to Charge Your Phone with Computer?

In daily life, manypeople will use their computer USB cable to charge their smartphone directly,because it’s both convenient and fast. Especially in public places where there
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?
Viewpoint 1: Using the computer USB cable tocharge the smartphone is very safe and will not damage the battery. The reason
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.
Viewpoint 2: Using a computer USB cable tocharge a mobile phone can cause harm to the cell phone battery. Because
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.
Forme, I don’t advocate the way of charging my cell phone with a computer. The
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.
The reason why it is not durable after charging a mobile phone
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?
Tricklecharging is used to compensate for the loss of capacity caused byself-discharge of the battery after it is charged. When the battery is charged
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.
Most
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.
After charging the phone with computer USB,don’t pull it out immediately. If time permits, you should charge it for
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.

choice to keep your investment safe.

The budget-friendly iPhone
SE gets an even friendlier price tag

Today you can pick up an iPhone SE with one month of pre-paidservice for $87.50. That’s down from the
usual $130 price tag and the best offer we can find. Apple’s iPhone SE delivers
stellar value at this price point, with a Retina display, 12MP camera, Touch
ID, and more. Ideal for kids or grandparents that don’t need the latest
technology.

Kenwood’s
7-inch CarPlay Receiver lets Siri be your co-pilot

Give your car an upgrade by picking up Kenwood’s7-inch Touchscreen Receiver at $380. Featuring
both Apple CarPlay and Android Auto, you’re looking at a 6.95-inch touchscreen

performance upgrades like better bandwidth and increased speeds. A whole slew
of retailers are currently offering a $100 discount on NETGEAR’sNighthawk AX8 Router, which is on sale for $300. This
is the best price we’ve seen so far, and a great way to future-proof your
home’s network. It packs up to 6Gbps network speeds, enhanced 8-Stream
multi-user connectivity, six Gigabit Ethernet ports and more.

Google goes after iPhone owners with aggressive Pixel 3A trade-in offers

Google’s Pixel 3A has a lot going for it
It has an excellent rear camera similar to the one found on the Pixel 3,
strong battery life and an OLED display. And at $399 for the 3A ($479 for the
larger 3A XL) there is already plenty to love about Google’s latest for those
looking for a new phone but who don’t want to spend the $700-plus that AppleSamsung and
Google charge for their latest top-tier devices.  
People looking to upgrade
from an old iPhone,
however, may find Google’s latest even more tempting. The search giant is
taking roughly $250 off the price of a 3A or 3A XL if you’re willing to trade
in an iPhone SE,
6 or 6S, with the number increasing to as much as $610 for those looking to
trade in an iPhone XS Max
While trading in one of Apple’s latest iPhones might not make the
most sense for getting the most bang for your buck, those with an aging device
already considering making the switch to Android may be hard-pressed to find a
better deal than a new 3A for $149. 
The exact values for the trade-in will vary based on your carrier,
storage size, condition of your phone’s screen and whether the device turns
on. 
Those with Verizon iPhones
seem to get the best offers, often scoring a few extra dollars compared to iPhones
purchased on AT&T,
T-Mobile, Sprint or a smaller provider, or those that are unlocked. Google
provides an “other” tab in the carrier section for unlocked phones
and ones purchased on smaller providers. 
An iPhone 6 16GB
will get you $252 on AT&T, $256 on Verizon and $248 on T-Mobile, Sprint or
“other.” 
Google’s trade-in system also seems to have some weird initial
quirks. A 32GB iPhone 7 on
AT&T has a minimum value of $203.50 while the 256GB version of the same
AT&T iPhone is $185.50. 
If you have unlocked your phone since purchasing it from a
wireless provider, classifying the carrier as “other” might also help
score you a few extra bucks depending on the iPhone you’re trading in.
Google is offering trade-in deals for Android devices from
Samsung, LG,
Motorola, Huawei as well as earlier Pixels,
though with the exception of the Galaxy S9 and Pixel 2 lines,
those values aren’t near those offered for older iPhones. 
Google’s iPhone deals are so intense that it is offering between
$246 and $264 for an iPhone SE. 
A new 32GB iPhone SE on Simple Mobile can currently be foundfor $124.99 at Target. Trading that into Google for a Pixel 3A,
choosing that “other” tab will get you $250, a net savings of roughly
$125 (not including taxes), giving those who don’t have an iPhone to trade an
easy way to buy one and save on a new Pixel.
