充电时是否可以使用手机？

You can use your phone normally while its charging, just make sure:
·You are using a genuine charger (or one that is from a reputable brand).
·The phone doesn’t feel too hot to touch.
·You are not near any liquids.

你可以在手机充电时正常使用手机，但要确保：
·使用的是原装充电器（或名牌充电器）。
·手机摸起来不太烫。
·附近没有任何液体。

Now, these are the hoaxes that cause this question to be asked frequently:
Taking a call while charging can electrocute you
Using your phone while charging can cause it to explode
Using your phone while charging damages the battery

下面这些是导致这个问题经常被问到的恶作剧谣言：
·充电时接电话会导致触电
·充电时使用手机会导致手机爆炸
·充电时使用手机会损坏电池

All of these can be easily debunked, and while some are partially true, these rare occurrences are mostly due to faulty chargers (most electrocutions), faulty phone designs (Note7) and liquid damage.

所有这些谣言都很容易被揭穿，虽然其中有一些掺杂了一点真实的东西，但那些罕见的事件主要是由于充电器故障（导致触电最主要的因素）、手机设计上的问题（Note7）和进水导致的损坏。

Let’s start with how the power supply in the phone works while charging:
·110–240V (AC) gets converted to anywhere from 5–20V (DC) by the charger
·5–20V is converted to 3.7–4.35V for the battery charging circuit
·3V-4.35V from the battery charging circuit is converted to 0.5V-1.8V for the chipset (newer chipsets run at lower voltages usually)

让我们从手机充电时的电源供应原理开始解释：
·充电器先将110-240V（AC）电压转换为5-20V（DC）的任意电压
·随后电池充电电路将5-20V电压转换为3.7-4.35V电压
·最后3-4.35V的电压经由芯片组处理转换为0.5-1.8V电压（越新的芯片组通常运行电压越低）。

Out of all of these voltages, only the mains voltage has enough energy to electrocute a person. Most chargers, however, are isolated from the mains power on the USB side and will not electrocute you, even if you have wet hands. Only poorly designed chargers will leak mains voltage. And this mains voltage is often the reason for the explosions too. The Note7 battery design had multiple faults, and it would still explode if the user was not using the phone while charging. This proves that the cause of the electrocutions and the explosions is due to a faulty charger (and sometimes faulty batteries) and not the phone itself.

在所有这些电压中，只有电源电压足以导致触电事故的发生。然而，大多数充电器会把电源电压在USB接口处隔开，因此即使你的手是湿的也不会触电。只有设计不良的充电器才会致使电源电压发生漏电现象，而这种电源电压通常也是爆炸的原因。Note7的电池设计有多个缺陷，就算用户在充电时不使用手机，它仍然会爆炸。这证明了触电和爆炸的原因是充电器有故障（有时是电池有故障），而不是手机本身。

If you feel any tingling sensation during charging, or if the touch screen registers false touches, then your charger is most likely not isolated well enough, and you should immediately dispose of the charger and buy a new one.

如果你在充电过程中有任何刺痛感，或者触摸屏记录响应了错误的触摸指令，那说明你的充电器很可能没有做好隔离（电压）措施，你应该立即扔掉这个充电器去买一个新的。

The last myth is that the battery is destroyed if you use it while charging, and usually the myth is never backed by a scientific fact, because there isn’t any. When you use your phone while charging, the phone charges the battery at a slower rate than normal, to allow enough power for the processor/screen. If anything, it increases the battery life by a very small amount because it is charging slowly and generating less heat inside the battery (that causes it to degrade).

最后一个谣言是，如果你在充电时使用手机会损坏电池。通常，这个谣言背后从没有科学依据作支持，因为根本就不存在任何科学依据。当你在充电的时候使用手机时，手机充电速度会比平时更慢，因为要为处理器或屏幕提供足够的电量。如果说会产生什么后果的话，那就是它能以非常小的幅度延长电池寿命，因为充电速度很慢，在电池内部产生的热量（这会导致电池退化）更少。

It is true that using the phone while charging generates more heat, because of the added heat due to the conversion of 5–20V from the charger to 3.7–4.2V, on top of the heat generated from charging the battery and conversion of 3.7V-4.2V to 0.5–3.3V required by the processors, but the phones have multiple safeguards to prevent dangerous situations:

的确,充电时使用手机会产生更多的热量，这些额外的热量源于充电器将5-20V 电压转换为3.7-4.2 V电压的过程、给电池充电的过程以及将3.7-4.2V电压转换为处理器所需的0.5-3.3V电压的过程中。但是手机有多个保障措施,防止危险的情况发生：

Charger shuts down if it overheats or if moisture is detected inside the USB port.
·Phone processor (CPU + GPU) switches to lower speeds as temperature increases
·Phone reduces radio power (e.g., switch to 3G/slower WiFi)
·Charging rate is lowered as temperature increases
·Charging software shuts off charging as a temperature limit is reached
·The OS shuts off the phone once a temperature is reached
·The battery physically disconnects from the circuit when a temperature is reached

·如果充电器过热或USB端口检测到潮气，充电器将被切断；
·随着温度的升高，手机处理器（CPU + GPU）切换到较低的频率；
·手机降低无线功能的功率（如切换到3G或频率更低的WiFi）；
·充电速率随温度升高而降低；
·当达到温度限制时，充电器内置软件会停止充电过程；
·一旦达到一定温度，操作系统就会关闭手机；
·当达到一定温度时，电池与电路断开物理连接。

So you should not worry about high temperatures.

所以你不应该担心手机温度过高。

However, it is well known that batteries function best at room temperature, so it would be ideal to not game on your phone while charging.

然而，众所周知，电池在室温下性能最好，所以充电时用手机玩游戏的体验会不理想。

I recommend that you avoid using your phone while charging.

我建议你避免在充电时使用手机。

Reasons:

理由：

1)  Heats up your phone

1）会使你的手机变热

2)  Now there's a specific time required for a battery to be fully charged, for example if its a 2000mAh battery then it'll need around 1 and a half hour to reach 100% if your not using it. If you are using it then it takes more time. Now if the battery is charged for a longer duration at 1 go then it begins to bulge or grow in size. Once the battery swells then you'll gave many problems.

2）现在的电池充满电需要一个特定的时间，例如：对于2000mAh的电池，如果充电时不使用手机的话，需要一个半小时左右才能完全充满电。如果你在充电的时候使用手机，那么充满电的过程会花费更多的时间。现在，如果电池在一次充满电的过程中充电的持续时间变长，那么电池就会开始膨胀或变大。一旦电池膨胀就会出现很多问题。

3)  I have experienced in some phones that if it is used for heavy games like asphalt then sometimes the battery even though is charging keeps on draining.

3）我曾经在使用某些手机时有过这样的体验，如果手机被用于玩像《狂野飙车》这样的大游戏时，那么即使是正充着电，有时电池也会不断地耗电。

4)  In some cases the battery explodes and can cause severe damage.

4）在某些情况下，电池会爆炸，从而造成严重的损坏。

yes, its normal to use android phone while charging. its only going to heat up your device that is due to flow of electrons inside the battery. Same thing we are doing with our LAPTOPS, BUT please avoid using it while answering phone call. it is dangerous due to increased radiation and potential explosion.

是的，在充电时使用安卓手机是正常操作。这样做只会加热你的设备，因为电池内部存在电子流动，我们的笔记本电脑也是如此。但是请不要在充电时接电话，因为这样会使辐射强度增加且有爆炸的可能性，这是非常危险的。

There are some myths regarding charing.

这里有一些关于手机充电的传言。

1.Charging your phone overnight kills the battery.
Your phone is smarter than you think. Once it's fully juiced up, it knows to stop charging. That means the battery isn't even in use at all.

1.整夜给手机充电会损坏电池。
你的手机比你想象的要聪明。一旦手机充满电，它就会停止继续充电，这意味着电池根本就不再被使用了。

2.Don't charge your phone until it's completely dead.
phone battery comes with finite numbers of charging cycles, everytime it completely drains reduce one charging cycle. so avoid this and charge your battery upto 60–80% to increase battery life.

2.要等手机完全没电了再充电。
手机电池的充电周期是有限的，每次电池电量完全耗尽，就会减少一个充电周期。所以应该避免这种情况，同时给你的电池充电至60-80%的电量，以延长电池寿命。

3.Using off-brand chargers destroys batteries.
its fine to use phone until you are using branded charger. off-branded chargers are made up of cheap material (semiconductors) which are likely to cause risk of explosion. Moreover, some of them aren’t ISO 9000 certified.

3.使用非品牌充电器会损坏电池。
在你使用品牌充电器之前，可能认为使用非品牌充电器充电时使用手机是可以的。非品牌充电器是由便宜的半导体材料组成的，这可能会导致爆炸的风险。此外，其中一些非品牌充电器没有通过ISO 9000认证。
