Research, the phone side charging side with the end good

Phone side charging side with in the end is good or not. Baidu a bit of this problem, the results of most of the answers are not good, to the small said, shorten the battery life, to the big said battery explosion, radiation increase, or even be electric dead and so on, then, what is the situation, we analyze (here said the battery, refers to the regular factory production, has protection circuit of the battery):

1, from the experience of daily use: First, the notebook can also be used to charge the side, in the large calculation, the current will suddenly increase, notebook why nothing. Second, when the phone is connected to the computer through the data cable, it will also charge, and will also operate on the phone memory, is not the side of the charging side. Third, when charging, the phone does not shut down, the program is still running, even if we do not do any operation, the operating system does not work.

2, from the circuit principle analysis: Charging line is 220 volts alternating current to 5 volts DC (or directly from the USB port output), and then received a battery protection circuit, finally received a battery, protection circuit can ensure that the battery is not charged, after the release no longer discharge. Simply say the principle of charging, you can think of the battery as a container, when charging, electricity is flowing to the battery, at this time, the power required by the mobile phone is provided by the charger (imagine, the battery charge and discharge is a channel, to the battery charging, how can there be power output?) ）。 Therefore, the so-called side of the charging side with, in fact, the charger at the same time to the battery and mobile phone power, when the battery is full, the protection circuit work, the circuit is cut off, the battery is no longer charged, but will not discharge, as long as the charging line is still next, the cell phone will not be powered by the battery

3, from the use of the situation: mobile phones, especially smartphones, there are many uses, traditional functions call, send text messages, new features to the Internet, play games, the most power consumption or display. From the above analysis we know that when charging the phone is powered by the charger, but, there is an exception, when the phone needs a very large current (do not know if this situation exists), the charger can not provide, at this time, the battery will discharge, even so, the battery output power is not usually large, because, and a charger to help it.

In short, the battery charge and discharge only one channel, either charge, or discharge, there is no side charge side discharge problem, the conclusion is that the phone side charging side with nothing bad, if not afraid of trouble, has been dragging the charger with, can also reduce the number of battery discharge, prolong battery life. However, this is also risky, because none of us can guarantee that the battery charge and discharge protection circuit characteristics never change and the quality of foolproof, so drag the charger, your battery will be in the long-term dangerous edge hovering, lithium battery is very delicate, overcharge and over discharge will cause great damage to the lithium battery.

Opinion, welcome to shoot bricks.

Another: indeed heard the side of the phone while playing the battery explosion of the news report, I explained that: because the side of the charge, the phone has been charged, if the charge protection circuit did not work or failure, because the play time is too long lead to battery long time charge (overshoot) and thus explode.
