Mobile phone is an important tool in our daily life and work. We should protect our mobile phone if we want to use it for a long time. Today we're going to talk about the precautions for charging smart phones. What's the best way to charge mobile phones?
How do you usually charge your mobile phone? Charge the battery to 100% at a time? Overnight directly? Or wait until the battery is exhausted before charging? To charge your mobile phone correctly, you'd better use the following ways.
01
The best way to charge a mobile phone is to charge it as soon as possible, a little at a time. Even if it's just a few minutes, sporadic charging will not damage the battery.
02
Don't wait for the battery to run out before charging the phone. The so-called "deep discharge", that is, when the battery is almost exhausted, recharging it will cause great loss to the battery.
03
Try to keep the battery power ratio between 65% and 75%. If you can always keep the battery life of the lithium battery in the smartphone between 65% and 75%, the battery life is the longest.
04
If you can't do point 3, try to keep the battery power ratio between 45% and 75%. The sub optimal range of smartphone batteries is 45% to 75%. For most people, this is more realistic in daily life. In fact, you can develop a daily habit of recharging your phone at a specific time to keep the battery within that range.
05
Do not charge the battery from a very low percentage at one time. Charging the phone battery from 25% low to 100% will reduce the battery capacity and shorten the battery life. Research has shown that batteries, like people, don't want to be under pressure and don't always expect it to be full. In fact, it's not a good idea to charge from any level to 100%. Lithium batteries' don't need to be fully charged, there's no need to do that. "Therefore, it is recommended to unplug the charger before the battery is fully charged (98%, 99%), or as soon as the battery is fully charged.
06
It's best not to charge your cell phone overnight. Although today's smart phones use lithium-ion batteries, when the battery is fully charged, it will automatically cut off the power supply and will not continue to overcharge. But it was also said that it is not the best way to fully charge the mobile phone, so there is no need to charge the mobile phone overnight.
It should be noted that the mobile phone charger used must be a regular charger, preferably the original charger. Some fake or mismatched chargers are better not to be used to charge mobile phones at night to prevent poor quality of chargers, which may cause the chargers to burn down and damage mobile phones.
07
Even if you want to fully charge your phone, you should pay attention to one thing: once the battery power of your phone reaches 100%, you should stop charging immediately. If you do not unplug the power supply after the battery is fully charged, it will keep the battery fully charged. Although it will not explode, it will accelerate the battery loss.
These practices also affect battery life
Different models of mobile phones are equipped with their own chargers when charging with non original chargers. If using non original chargers, the current of chargers may be too large, which may have an irreversible impact on battery performance.
While charging, using mobile phones to make calls, play games, watch videos and so on are all high current consumption. The current provided by the charger is less than the current consumed by the mobile phone. When using mobile phones while charging, it needs to output current from the battery. That is to say, at this time, the battery is not charging, but discharging, even making the battery capacity quickly 'dry'. The life of lithium battery is closely related to the number of charging and discharging cycles. When the cell phone is used while charging, the battery can switch between charging and discharging states rapidly, which will affect the life of the battery.
When the mobile phone is placed in a high and low temperature environment, due to the instability of the electrode in the electrolyte, each time the battery is charged and discharged, the two electrodes of the battery will have a chemical reaction, and then the active substances will be consumed, the chemical energy converted into electrical energy will be reduced, and the battery capacity will be reduced. However, if the ambient temperature is too high, the chemical reaction and 'self discharge' of the battery will be accelerated, and the battery capacity will be reduced; if the temperature is below zero, the battery structure will also be negatively affected, even permanent damage.
