Does the cell phone battery have a lifespan? How long does it take to change it? Read it and you will understand

The cell phone battery is an important configuration that many people are concerned about, and it is closely related to the service life of the cell phone. When the phone battery aging, the range will be significantly reduced,Battery recycling seriously affecting the use of experience.

In fact, the battery also has a life expectancy, and when it reaches a certain level, it needs to be replaced. Therefore, many people will have questions: how long is the life of the cell phone battery? How to determine whether the battery has reached the life span? Let's explore this below.

First of all, the life span of a cell phone battery depends on its type. At present, cell phones mainly use lithium batteries and nickel-metal hydride batteries.

In the past, cell phones used NiMH batteries,cylindrical cell assembly machine and people would usually charge them for 12 hours after purchasing them to activate the battery. This is because of the memory effect that exists in these types of batteries.

In contrast, cell phone batteries nowadays do not have this problem because they usually use lithium batteries that do not require special activation. Therefore, when you buy a new cell phone, you do not need to charge it for more than 12 hours, just charge it normally.

Of course, the lithium batteries of cell phones have a certain life span.battery making machine It is known that the life of a cell phone battery is about 500 cycles, but it should be noted that this number of cycles does not refer to the number of charges.

One cycle represents the process of the battery going from fully charged to empty and then from empty to fully charged.

For example, if you fully charge a cell phone, use part of the charge, and then fully charge it again, even though you've charged it twice, it's just a cyclic state.

As a result, cell phone batteries nowadays can be used as they are charged, rather than having to wait until they run out of power to recharge.

In the past, cell phone batteries had a smaller capacity and usually reached the number of cycles in about one to two years. Nowadays, cell phone batteries usually have a capacity of more than 4000mAh, and can basically be used for more than two years under normal use and without serious impact.

However, when the number of cycles reaches a certain life expectancy, the battery can still be used if it has not been crashed or otherwise damaged, except that the battery's capacity may only be 60% of its initial capacity.

So, when do you need to replace your cell phone battery?

The cell phone batteries currently on the market are very durable, and generally have no problem using them for three to five years, so there is no need to replace them.

But some people due to bad charging habits and use habits, resulting in shortened battery life, just two or three years to become less durable. If the cell phone is often fully charged and can only be used for one or two hours, then it means that the life of the cell phone battery is coming to an end, and then you need to consider replacing a battery.

In addition, when a cell phone is used for more than three years, the phone may experience problems such as lag or lack of memory, and many people will also choose to simply replace a new phone.

Therefore, when it becomes apparent that the battery is not lasting as long as it should, it is important to consider replacing a battery or just replacing the phone.

In order to extend the life of your cell phone battery, you can follow these principles:

1. Don't wait until the battery is depleted to charge it. Try to start charging when you have more than 20% of power left, which is better for the health of your battery.

2. Charge when you can. Many people are used to waiting until the power is depleted before charging, thinking that this will prolong the life of the battery. However this is not the case. When the battery is in a super low state of charge, it will instead cause some wear and tear. Therefore, you can usually use odd hours for charging, and often charge it, you don't need to be fully charged, just keep it in a charged state.

3. Keep the power at 60-80% of the best. It is understood that the proportion of lithium battery power to maintain at about 60-80% is the best state, which can improve the life of the battery. Therefore, you can usually use it as you charge it, and it is good to keep the power in this proportion.

4. Use a regular original charger. Using an inferior charger can cause some damage to the battery. Some people will buy a charging cable at random or often borrow other people's chargers to charge when the original charger is broken. This practice is wrong. Although some regular chargers are still acceptable, if you use a cottage charger or an unsuitable charger, it will also cause damage to the battery.

5. Don't keep charging for a long time. Nowadays, cell phones will automatically cut off when they are fully charged. Therefore, many people don't think of charging for a long time overnight. Although it will automatically cut off, keeping it in this fully charged state will also speed up the depletion of the battery.
