First, the phone is completely no power to charge! Big mistake
Is it customary to recharge the phone before it runs out of battery power? Is it possible to see the cell phone battery lit red (less than 20%)? It is not recommended. Battery University noted that the lithium-ion battery used in smartphones is not a nickel- There will be a so-called memory effect. On the contrary, for lithium-ion batteries, completely discharged on the battery more damage.
Second, the phone must be charged to full charge! Wrong
Battery University study, fully charged (100%) will make the battery in a state of high pressure, the battery caused by the pressure so every charge, in fact, not necessarily full.
Third, all night charging, the next day holding 100% of the phone's best cell phone! Do not do this
For many modern people, cell phone charging before going to bed, and then all night long until the next day to wake up, it is a habit of many people.But as mobile phone charging does not have to be filled to the full concept of charging on behalf of the phone all night Will continue to be under high pressure after charging up to 100%, which is not good for the cell phone battery.Although most mobile phone brands can take the initiative to protect their mobile phones after the mobile phone is fully charged under the continuous evolution of mobile power management technology, Can not be denied that there is a real safety charge more worrying all night.
In the end how to charge the phone right?
First, can charge on the charge
It is a good idea to charge your phone when you charge, even if it only takes a few minutes, charging for a short period of time will not do any harm to the battery.
Second, the power to maintain the best between 65% ~ 75%
If you can keep the cell phone power in the range of 65% to 75% is the best of course, to force to maintain in this state have some difficulties, so try to keep like, if not, the second best power range of 45% ~ 75% .If it is still difficult, try to keep the power between 25% ~ 75% .For the battery charge interval, if the charge is too low before charging, it will consume more battery charge cycle.
In addition, the lithium battery has the best working temperature, try not to use the phone in too low temperature, too high environment, but also to further extend and protect the life of the phone battery.Apple official website pointed out that the best iPhone battery Operating temperature is between 0 ° C and 35 ° C. Also, "using an iOS device in extremely cold conditions (out of its operating range) may temporarily reduce battery life and cause the unit to shut down"
Not only that, "iOS devices in extremely hot conditions may permanently reduce battery life." So, if you have a habit of driving, do not accidentally forget your phone in the car in the summer because it is likely Because the car temperature is too high for the phone battery to bring permanent damage.
Note: how to calculate the cell phone charging cycle? With the cell phone battery fully charged (100%) to calculate, when you charge the battery to 50% of the time, then you have consumed 1/2 charge cycle; if the phone is full After you charge it again when the phone is depleted to 50%, you consume another 1/2 charge cycles, which, in summary, consumes 1 charge cycle in total.
