I believe you have heard this statement, "the new cell phone must be charged for more than 8 hours and repeated several times to fully charge and discharge, this process is called activation, which can make the phone's replacement battery achieve its maximum capacity." Is it right?
There are indeed some batteries that require such activation work. But it’s the nickel-cadmium rechargeable batteries and nickel-metal hydride rechargeable batteries. These batteries have a phenomenon called "memory effect". Charging in the state of incomplete discharge would easily overcharge the replacement cell phone battery.
However, the batteries used on our phones and laptops are mostly lithium-ion batteries now. Although the lithium-ion replacement cell phone battery is small, it can store large energy and is used more and more widely. Lithium-ion batteries do not need to be activated through complete charge and discharge at the beginning of use, because the battery initialization and testing process has been completed in the process of manufacturing of the phone battery. Lithium-ion batteries do not have the so-called "memory effect" and can be charged at any time. The saying that the lithium-ion cell phone battery should be fully charged and discharged regularly is only for calibrating the electricity detection devices in notebooks and some high-end smart phones. It is not because it would do good to the phone battery itself.
Reducing the charge times can extend replacement cell phone battery life?
Generally the lithium-ion replacement cell phone battery can have hundreds of charge-discharge cycles. We can often see such a statement in the battery and device manuals. The charge-discharge cycle refers to the process of using up the phone battery and then fully charging it. Continuous deep charge and discharge for lithium-ion battery would affect its life. However, under the daily charge and discharge conditions, the life of lithium-ion replacement phone battery is actually quite long.
In addition, if the lithium-ion batteries are put aside, its capacity would also lost naturally, the main influencing factors are voltage and temperature. Research shows that the capacity of the lithium-ion batteries would significantly lost if it’s stored in a fully charged state for a long time. The higher the temperature is, the faster the lithium-ion replacement cell phone battery capacity loss would be, and this loss is irreversible, that is to say, the phone battery capacity will be permanently smaller.
So what is the correct approach? First of all, frequent charge and discharge would be better to extend the replacement cell phone battery life than deep charge and discharge. We’d better charge for the phone battery when we have time. In addition, try to reduce the time that the cell battery is fully charged. If we do not unplug the power supply after fully charged, the battery would always be at a state of full power. Although it would not explode, it still would speed up the loss of cell battery capacity.
In addition to our daily habit of using the phone, there is one element that we can not change, that is the battery quality itself. If we have to replace the new battery, we should choose the high quality one.
