In the era of lithium batteries, mobile phones can be charged at any time as long as they are not fully charged. But often because of the neglect of the details, our battery is invisibly hurt. So sometimes the new mobile phone has been used for a few months, and there will be problems of fast power consumption and short battery life. So what are you overlooking about these details of charging?

How much power is left, which should charge the phone?
According to the efficiency, the general mobile phone has the fastest charging efficiency when 15%-20% of the battery is left. Therefore, it is not recommended to charge when the phone is running low because the phone will receive too much current. Of course, it is not recommended to charge when the power is higher than 50%, because this will not only reduce the charging efficiency, but also cause the voltage to rise to 2 peaks and the battery is lost.
This is probably why some mobile phones will remind you to charge when the power is 20%, and the red warning will be too low when the phone is 10%. So when it comes to integration, in fact, when the power is around 20%, we should "eat" the mobile phone.
How much is the battery maintained, and the phone is the most stable?
Generally, when the power of the mobile phone is maintained at 40%-60%, it is relatively ideal. At this time, the battery will not be too high or too low, so the power can be maintained relatively stable. A slightly more careful person should find that when the mobile phone's power is at 100%, the battery will easily consume less than 90% during use, and when we are below 60%, the mobile phone's power consumption will be Relatively slow.
So when you go to sleep at night, more than 40% of the mobile phone's power can not let it stand up for the night, so that the battery is in an ideal and stable state, the battery capacity will be reduced, which will better protect the battery life of the phone. .
Some mobile phone brands like we know have an automatic power saving mode. For example, when the power is lower than 60%, it will automatically enter the intelligent power saving mode, thus ensuring that the mobile phone can maintain a stable power between 40% and 60% for a longer period of time. .
Is the mobile phone full? How much is it suitable?
Under normal circumstances, when the mobile phone is charged to 95%, the charging can be ended. Because the mobile phone lithium battery is fully charged, it will generate high voltage, which will cause more pressure on the battery itself, which will seriously affect the battery life in the long run. So it's time to put down 100% of the feelings, after all, not everything needs 100% to measure.
What is the impact of overnight charging on mobile phones?
Many people charge their mobile phones before going to sleep, but because they don't want to pull up their mobile phones in the middle of the night, many people's habit is to keep the phone charging for one night. So what impact does mobile phone overcharge have on mobile phones?
The smart phone has a power management chip and a battery protection board on the lithium battery device, which can effectively prevent overcharge protection, so it is safe to overcharge, but long-term overcharge will definitely have a certain impact on the mobile phone battery. Therefore, it is recommended here that for the performance of mobile phones, high-end machines are best not to overcharge the phone for one night. For security reasons, it is best not to overcharge the low-end machine for one night.
How does temperature affect battery life?
The mobile phone battery is a sensitive component, so if the temperature is too high, the battery's capacitance loss rate will be higher. Therefore, we do not recommend playing the mobile phone while charging, because it will cause the mobile phone to heat up and affect the battery. Therefore, when charging the mobile phone, it is best to unload the protective case that does not dissipate heat. Of course, if the mobile phone is very hot, you can use an external means such as an electric fan to relieve the heat of the mobile phone.
When the temperature is too low, the machine friends in the north must experience a lot. The low temperature will make the phone consume power quickly, and some will even freeze it. That is because the output voltage of the battery is lowered in a low temperature environment, and the discharge capacity is suppressed. Too high or too low temperature will affect the life of the mobile phone battery to varying degrees, so in the mobile phone charging, the ambient temperature of 25-40 degrees will show its best performance.
