First of all, battery overdischarge is the first point, because most smartphones use lithium batteries, which have lithium ions, which has a certain degree of activity, if the cell phone overdischarge, it will certainly affect the battery life. So the best way to avoid this is to recharge the battery when needed, instead of using it every time, hoping to shut down the battery.
The second point is that the temperature of the mobile phone exceeds the normal range. It is not only too high, but also too low. Because this kind of lithium battery is most afraid of the irreversible damage caused by temperature. Whether it is too high or too low, it will cause different degrees of loss. So what we need to do is not to overuse the phone to cause it to get hot and not to put it in a particularly cold place.
Therefore, we can see from the above two points that even when wireless charging tools are working, if part of the energy is converted into heat, it may lead to excessive cell phone temperature, leading to battery loss. So it is not unreasonable to say that wireless charging technology will lead to battery loss.
After understanding the reasons that wireless charging technology may cause battery loss, I believe that not only can we ordinary people see, but also where are the shortcomings of this wireless charging technology? Mobile phone manufacturers are sure to find the drawbacks of this technology as well. So there are many solutions, for example, some wireless chargers with heat dissipation function, and another solution is that the transmitter and mobile phone do not contact directly. This kind of thing is really done, charging at a distance, in this case, heat generation is very little, and the harm to the battery is limited. Therefore, this wireless charging technology on the market will cause damage to the battery, is completely considered by mobile phone manufacturers to solve the problem, and need not worry too much.
What about? After reading the above analysis, you can rest assured of the bold use of wireless charging, right? In fact, whether it is wireless or wired charging, in a word, we should pay attention to the two reasons mentioned above, one is excessive discharge, the other is abnormal temperature. In life, no matter what kind of charging technology you use, you should avoid these two kinds of reasons causing damage to mobile phone batteries.首先第一點就是電池過放，因為智能手機(jī)使用的大多是鋰電池，其中擁有鋰離子，這是有一定活性的，如果說手機(jī)過度放電，肯定是會影響電池壽命的。所以說，為了避免這一點最好的方法，其實就是需要的時候就充電，而不是把電池每一次都用到，恨不得要關(guān)機(jī)的狀態(tài)。
第二點就是手機(jī)的溫度超過正常范圍，這里并不僅僅只是溫度過高，也可能是溫度過低。因為這種鋰電池最怕的就是溫度帶來的不可逆?zhèn)?。無論是過高還是過低，都會造成不同程度的損耗。所以說大家需要做到的就是不要過度的使用導(dǎo)致手機(jī)發(fā)燙也不要把他放在特別冷的地方。
因此從以上兩點我們不難看出，哪怕是無線充電工具在工作的時候，如果說將部分能量轉(zhuǎn)化為熱能的話，也可能會導(dǎo)致手機(jī)溫度過高，從而導(dǎo)致電池?fù)p耗。因此之前的那些說法，無線充電技術(shù)會帶來電池?fù)p耗并不是沒有道理的。
再了解了無線充電技術(shù)可能造成電池?fù)p耗的原因以后，我相信不僅僅只是我們平常人能夠看的出來，這種無線充電技術(shù)的缺陷在哪里？手機(jī)廠商肯定也能發(fā)現(xiàn)這種技術(shù)的缺點。因此也有很多解決方案，比如說，有的自帶散熱功能的無線充電器，還有另一種解決方案就是發(fā)射器和手機(jī)不直接接觸。這種事真的做到了，相隔一段距離充電，這種情況下，熱能產(chǎn)生就非常少，對于電池的危害也有限。因此市面上這種無線充電技術(shù)會對電池造成損害，是完全被手機(jī)廠商考慮解決辦法了的，并不需要太過擔(dān)心。
怎么樣？看完了以上的分析后，大家可以放心大膽的使用無線充電了吧？其實無論是無線還是有線充電，總而言之，都要注意，以上提過電池?fù)p耗的兩個原因，一個是過度放電，一個是溫度不正常。在生活中，無論你使用的是哪種充電技術(shù)都要避免這兩種原因?qū)κ謾C(jī)電池造成傷害。
