Does cell phone battery have a memory effect?

Introduction Does cell phone battery have a memory effect? There is almost no malignant memory in the lithium batteries used today, that is, they do not run out of power, unlike cell phone batteries of the past, which cannot use their capacity only when charging. hand

Does cell phone battery have a memory effect?

Lithium batteries used today basically have no malignant memory, that is, they do not run out of power, unlike cell phone batteries of the past , which can only use their capacity when charging.

Usually, the mobile phone shows the battery level when it is 20% used. If possible, you can charge it directly when the battery is full, you can unplug the charger after a while.

It must be said that cell phones are pre-charged when they leave the factory. A new mobile phone will have power when it is turned on, which means the battery has been charged and discharged frequently.

Of course, although there is no malignant memory in mobile phones, there is a limit to the number of times it can be charged. Use the phone as long as possible and charge it below 10% to reduce thecharge. number of times it needs to be recharged.

Why do lithium batteries not have a memory effect

Understanding the memory effect: The battery memory effect refers to the Reversible battery failure, i.e. battery performance that can be restored after a failure. Memory effect This means that the battery automatically maintains this specific trend after undergoing a specific duty cycle for a long time. This was first defined in nickel-cadmium batteries. Cadmium batteries, and there is a memory effect in sintered batteries. And now, nickel metal hydrogen batteries (commonly called nickel metal hydride) are not bound by this definition of the memory effect, but they are inert and must be activated first. Generally, they can be charged and unloaded 300-500 times. After that, they will find that the duration is moreshorter. If you want to replace your cell phone, it is best to put the old battery in the compartment. refrigerator for a few days, then use it again, which will improve performance.

Lithium batteries are different from nickel-metal hydride batteries and do not have a memory effect

"People think that lithium batteries do not have memory effects, which is false. This is irresponsible deception on the part of companies. Lithium batteries also have memory effects, but their memory effects are weaker and less obvious. In addition, there are two types of lithium batteries, one is lithium battery and the other is lithium ion battery. . It is not very safe to use and often burns and explodes when charging. It is a problem. This may be because the lithium is too active. Later, BatteriesImproved lithium-ion batteries have been added to inhibit the activity of lithium, making lithium batteries truly safe, efficient and practical. Older lithium batteries have also followed suit. As for how to distinguish them, they can be identified from the battery label, lithium battery. is LI and the lithium-ion battery is LI-ION. Now the so-called lithium battery used in laptops and mobile phones is actually a lithium-ion battery.
