Cracking the Internet rumors of various mobile phone lithium battery charging rumors

Cracking all kinds of mobile phone lithium battery charging rumors on the Internet There is a joke on the Internet that: Men with iPhones are good people, because they have to go home every day to recharge their phones. In order to improve the capacity of your mobile phone battery, let the battery regenerate in the same place with whole blood faster, and take advantage of every surprise. One of the most popular tricks recently is that if you set your phone to float, the charging speed will be doubled. Is this true? The author conducted an on-site investigation, and the result was not so optimistic. At the same time, in response to the rumors circulating on the Internet that the standby power of the mobile phone is released, and the storage capacity of the frozen forward old battery is used, the author has also done experiments. The results and the analysis of experts have confirmed that this rumor is basically unfounded. The hover mode does not allow the charging speed to fly. Internet rumors: set your phone to hover mode, and the charging speed is twice that of the normal mode. Author's experiment: In order to promote the accuracy of the experiment, the author prepares three mobile phones: iPhone4, which has been used for more than 3 years, Samsung S4 has been used for less than 3 months, and Lenovo A288T has been purchased for more than 1 year but has not been used. Test method: Charge 3 mobile phones normally within 20 minutes. Then set all three phones to hover mode and charge them for another 20 minutes. Test results: iPhone4 battery increased by 20% in normal mode and 20% in hover mode; Samsung S4 increased by 20% in normal mode and 21% in hover mode; Lenovo A288T 18% more power has been added in normal mode, and 19% has been added in hover mode. From the results of the three sets of tests, it is not difficult to see that in the soaring mode, even if the charging speed can be accelerated, the number is small, and the double speed of the network transmission has nothing to do with this. Professional interpretation: What are the differences between the soaring method and the general method of charges? The author interviewed Professor Zhang Junliang, director of the Fuel Cell Research Institute of Shanghai Jiaotong University. Zhang Junliang said that the way of flying is nothing more than hindering the work of some programs, and then reducing power consumption. Assuming that there are fewer programs running during normal charging, the test result is closer to the actual situation. Because as far as the charging itself is concerned, there is no essential difference between the soaring mode and the normal mode. Engineers Luo Xianlong (transliteration) and Zhang Junliang (transliteration) working in battery factories have the same idea. He told the author that in fact, the most power-consuming part of a smart phone is the screen, and the hover mode cannot turn off the screen, so make sure that the phone screen is turned off when charging, and the charging speed will be faster. In addition, he added that it is actually the maximum current output power of the charger that determines the charging speed of the mobile phone. Within the maximum milliampere range that the mobile phone can withstand, the output power of the charger is larger and the charging speed is faster. Announce the mobile phone standby instructions, the mobile phone can not understand the Internet rumors: When the mobile phone is out of power, just enter *3370# on the dial pad, dial out, the mobile phone will restart, and you will find that the battery power has increased by 50% after turning on the phone. The author’s experiment: I typed the *3370# command on the dial keyboard in the above i-phone4, samsungS4, and lenovoA288T mobile phones. The mobile phone flashed an execution request error, and I did not know the error. Professional explanation: Engineer Luo Xianlong said that there is no such thing as a standby command to release the battery. This *3370# command is more like the previous mobile phone coding method, and should not be directed at the battery. Now smart phones generally use ios, and Android systems do not use this code. The battery has been frozen for 3 days and 3 nights, only extended standby for 2 hours. Internet rumors: Put your phone battery in the refrigerator, freeze it for a period of time, then take it out and continue using it, the battery will be more durable than before freezing! Author experiment: remove Lenovo A288T The cell phone battery is sealed with plastic wrap and placed in the refrigerator. After 72 hours, the reporter took out the battery from the refrigerator, cooled it for a while, then put the battery in the phone and turned on the phone. The battery life was extended by two hours for the first time; after charging, the standby time returned to the refrigerator.
