In this era of the machine does not leave the hand, in addition to the balance is not enough, the lack of power will also make us anxious and insecure, and therefore charging the phone has become almost a must-do thing for most people every day. However, many people still have some misconceptions about the small matter of cell phone charging, such as cell phone power below 20% before charging, different devices can not be mixed with the charger, etc. ......
Are these claims reliable? The following professor to talk to you specifically ~
Myth #1: Charge your phone below 20% and then charge it
This statement has spread a bit of historical reasons, the previous cell phone with nickel-cadmium batteries, this battery has a memory effect, often charged only when the power is relatively high may affect the battery capacity, so the previous cell phone has "phone power below 20% and then recharge the battery can protect" the statement, in order to discharge some thoroughly to reduce the memory effect.
However, the current smart phones are basically using lithium batteries, lithium batteries mainly rely on lithium ions moving between the positive and negative electrodes to work, it has no memory effect, can be recharged at any time, but lithium batteries are most afraid of excessive discharge, so there is no need to wait until the power is below 20% and then recharge.
Myth 2: Charging your phone all night will damage the battery
This is completely overthinking, now the smartphone is far more intelligent than you think, when the battery is full, the phone can automatically identify and stop charging, it will not continue to charge.
PS: Although charging the phone all night will not damage the battery, but the professor also does not recommend that you charge the phone all night, there are relevant data show that: compared to maintain 100% of the power, the phone power to maintain the middle power (40%-80%) can effectively extend the battery life.
Myth 3: Non-original chargers can harm the battery
Most manufacturers will advise users to use the original charger, charging faster and safer, which is also a kind of publicity for manufacturers to guide users to buy their accessory products.
In fact, after the regular certification of the third-party brand charger can also be used, the same support for fast charging, but also to protect the battery, over-current, over-voltage, over-temperature and short-circuit safety protection are available, do not worry.
It should be noted that the cottage counterfeit charger is really damaging to the phone battery, and there are safety hazards with it, so when you buy it, you should choose the regular brand production, over the certified products.
Myth 4: You can't mix chargers between different devices
The main reason for this statement is that if chargers with different specifications charge the phone, there is a risk of damaging the battery in case of high voltage.
And in fact, now the regular charger, generally compatible with a variety of charging protocols, and can intelligently identify the access to the device to allocate the appropriate voltage and current to its charge, there is no high voltage damage to the battery.
Take an East hot selling Green Union small lipstick 65W GaN charger, the highest support 65W, compatible with PD2.0, PD3.0, QC2.0, QC3.0, QC4.0, SCP, AFC and Apple 5V2.4A and other fast charging protocols, in addition to Apple, Huawei and other mainstream cell phones, but also to some laptops, tablets, Switch, Bluetooth headphones, etc. Fast charging.
Myth 5: When the phone is low, the radiation is a thousand times greater
This rumor is really outrageous, the radiation strength of the cell phone and its remaining power can be said to be eight sticks and no, it is only related to the signal strength.
Compared to the best signal, the worst cell phone signal when the intensity of radiation may be a thousand times greater, but in fact, it is still within a very small range, is within the national regulations, so we do not have to worry too much. This rumor should be confused with "a frame of electricity" and "a frame of signal", to make such a mess.
