How do I charge my phone's new battery?
1. How to charge a new battery
When using a lithium battery, it should be noted that the battery enters a dormant state after being placed for a period of time. At this time, the capacity is lower than the normal value, and the use time is also shortened. However, lithium batteries are easy to activate, and the battery can be activated after 3-5 normal charge and discharge cycles to restore normal capacity.
Due to the characteristics of the lithium battery itself, it has almost no memory effect. It is best to use the standard method of charging from the beginning. This "natural activation" method is the best.
For the "activation" of lithium batteries, the most common saying is that the charging time must exceed 12 hours, repeated three times in order to activate the battery. In fact, this is a misunderstanding, which is obviously a continuation of nickel-cadmium batteries. Long-term overcharging is very harmful to lithium batteries, so it is best to charge according to the standard time and standard method, especially not to charge for more than 12 hours. Usually, the charging method described in the mobile phone manual is the standard charging method suitable for the mobile phone.
2. Does the lithium battery need to be "trickle" charged?
Lithium battery phones or chargers will automatically stop charging when the battery is fully charged, and there is no so-called "trickle" charging that nickel chargers last for more than 10 hours. That is to say, if the lithium battery is fully charged, it will not be charged by the so-called "trickle" if it continues to be placed on the charger.
In addition, on some mobile phones, if the charger is not removed after charging for a certain period of time, the system will not only stop charging, but will also start discharging into the charging cycle. This is the self-protection setting of mobile phone manufacturers for lithium batteries.
It is also worth noting that lithium batteries are also not suitable for over-discharge. Over-discharge poses a serious risk to lithium batteries, which may cause permanent damage to the battery. Most seriously, this may not work properly. Therefore, when you use it, you must charge it even if you see the power alarm.
3. Rational timing of charging
As mentioned above, lithium batteries have almost no memory function, but they are still limited by the number of charges. Generally speaking, the cycle life of most lithium batteries is around 1000 times. Therefore, many people are committed to using mobile phone batteries to automatically shut down before charging. In fact, this is a completely unscientific method. The principle of recharging the battery after the remaining power is used up does not tell you to use the battery until it is completely dead.
A saying as widely circulated as long charging is "try to use up the battery of the mobile phone, it is best to use automatic shutdown". This practice is actually only used on nickel batteries, the purpose is to avoid the memory effect, unfortunately it is also spread on lithium batteries.
Once, after a warning that the battery of the mobile phone was too low appeared, some people still did not charge and continued to use the example of automatic shutdown. As a result, the mobile phone in this example did not respond during subsequent charging and booting, and had to be sent to customer service for maintenance. This is actually caused by the voltage of the battery being too low due to excessive discharge, so that it does not have normal charging and booting conditions.
