Feng to share Why use a computer for charging the mobile phone not durable

In daily life we may experience this issue: after using computer USB charge smart phones, power consumption of the phone seems to be faster than the charger after charging, so what exactly is causing this phenomenon? recently, Feng “mobile digital life” gives us the answer to this question.

The front said, after using the computer for charging the mobile phone not durable because, our phone is not fully charged. In other words, although we have a smart-phone display power 100%, but in fact, this is false. As an analogy, if the battery is in a bottle, even if you filled it with stones, can still hold a lot of water inside.

However, on a computer USB charging of a Smartphone is not “hold water” of this link, why has this come about? actually, and cell phone battery charging mode. Mobile phone charging are, fast charge, the final stage of charging, need a trickle charge (like a bottle with water), it is only the real power.

The so-called trickle charge is mainly used to cover the battery at full charge capacity loss due to self-discharge. After the Smartphone’s battery is fully charged, due to the self-discharge capacity loss is the standard size of about 5%, if there is no remedy, this 5% part is easy to believe that the battery power consumption rate is accelerating.

Front “mobile digital life,” says trickle current is too small, and the process has been very slow, and we tend to advance line out, which is 5% power instantly gone, even if the phone displays of power still 100%, this algorithm, which is only energy. Kenzo france

In addition, computer USB 5 v voltage, this voltage can not meet today’s demand for Smartphones that 9V/12V the fast charge (that is, USB charging with a computer is very slow), and current up to trickle charge standard, so people would think phone computer USB charging dissatisfaction, even if “full”, they would think the cell phone away quickly.

In this case, we have to think about a problem, using a computer USB charge smart phones safe? will give us Smartphone battery caused some damage in this respect?

For this problem, Feng “mobile digital life,” and using computer USB charge smart phones is very safe and will not damage the battery. The reason is that now the phone is the charger or the USB charging on the computer, all through the same USB cable. Different ways of charging charging current of difference only, regular charger and computer USB charging, it is only the difference of speed. Kenzo france

On the “computer for charging the mobile phone not durable” the solution of this problem, Feng friends if there are differences of view, message exchange.
