When You Charge Your Phone, The Battery Goes Up To 100%. Why Does It Stop There?

Most mobile phone companies provide the facility of showing the users at the percentage of their battery level. People have different views about the ideal percentage, but have you ever thought about why the charge percentage does not go above 100 percent?

 

Why does the battery level no go above 100 percent?

 

There are multiple reasons why battery percentage does not go above 100 percent. Some of those reasons are provided by cellphone manufacturing companies, and some of these reasons are given by tech experts who have ample knowledge in the field of technology. Some of these reasons are listed below.

To protect the battery:

 

Nowadays, smartphones are expensive, and as a result, their components are also expensive. Protection is the battery is important because of two reasons. The first reason is that batteries can be expensive to replace and cost you a lot of money. So, the cellphone company should take preventive measures to protect the battery in the first place. The second reason is that it may damage the mobile phone and cost you a lot of money. Moreover, there can be a third reason also, and that is the reputation of the company. No company will want to ruin its reputation just because of faulty batteries. No one would want to buy any of their mobile phones then.

 

But how do they protect the battery? The cellphone manufacturing companies install software inside these mobile phones, and this software is called the power management system. The power management system carries out different procedures to prevent the battery from getting damaged. The first is that it does not take the battery percentage above 100 percent. Batteries can have a charge capacity of more than 100 percent, but this power management software does not allow it to reach its full potential.

 

If the battery charging would go above 100 percent, the battery can blast. But why does that happen? It is because companies that manufacture batteries only provide the safe limit on batteries and not the extreme limit, as a result, the limit at which the battery is damaged is different for every battery. So the power management system provides a universal rule not to charge batteries to their full potential and keep them at 100 percent. Some people keep on charging their phones even when the battery percentage is 100 percent. For safety purposes, cell phone manufacturing companies have kept the extreme limit at 100 percent so that the customers can not dare to charge it above 100 percent.

To prolong battery health:

 

Battery health is important for every mobile phone. If certain procedures are not taken, cell phone batteries would only last a year. Cell phone batteries are made up of lithium. A lithium battery can be identified very easily by just looking at the battery pack. You must have seen the words li-ion. It means that the product supporting the battery is made out of lithium. The main purpose of using lithium is to give longer battery timings.

 

The power management system has yet another benefit. There is one other reason why battery percentage does not go above 100 percent, and the reason is to prolong the battery health. If these steps were not taken, our battery health would drain, and we would be able to use our mobile phones for only an hour. Moreover, if the battery percentage does not go above 100 percent, it will not damage the battery’s lithium cells. If these cells are damaged, the battery can blast and cause damage to your mobile phone.

 

Most of the time, you must experience that when your battery gets low or reached zero percent, the phone will automatically shut down. But why does this happen? This happens so that the battery can not be damaged. Once a battery reaches its zero potential, it will be damaged for life. I will explain using an example. If your phone gets destroyed, you keep it right away in the cupboard without removing the battery. After some months, when you take out the phone, you will see that the battery’s shape has changed. The battery is thick and expanded. This happens when the battery reaches the lowest potential. The same thing happens when you take your battery to the highest potential. As a result, to prevent battery damage and give batteries longer health, the power protection software prevents the battery percentage from going above 100 percent.

 

To have the best battery performance:

 

Nowadays, smartphones are packed with so many features and functions that a layman would get confused. All these functions and features require a strong and powerful battery. But why? This is because most people buy cellphones for one reason, and the reason is that they need communities using calls from the sim cards. If these functions and features overpower the basic function of the cellphone, no one will buy it. There are two ways to tackle this problem, and that is to remove all the features or to add a massive battery. Both of these reasons are not feasible for the current world we live in as people need those features and functions in their daily lives too, and it would be impossible to own a smartphone and carry a big battery around with it.

 

Due to these reasons, experts thought they should keep the batteries small and increase their productivity. As I mentioned before, smartphone companies use lithium as a source to make their batteries. This was because lithium ions give the longest battery time, but there is just one defect to them. Batteries made from lithium are susceptible and can get destroyed when you don’t give them the proper care. For instance, experts say that you should not take your battery percentage above 80 and not above 100 percent.

 

People say that you should take the percentage to 100 percent to consume the most out of your battery, but this can be harmful to your battery. Lithium ions are sensitive, and you should not heat them a lot. If you take them to the full potential, you can hear them a lot and cause damage to them. As a result, experts say that you should keep it between 80 and 100 percent to have a better battery percentage.

Risk of phone damage:

 

As I explained earlier, if we do not carry out certain procedures, we can damage the battery. And that happens if we take it above 100 percent to its full capacity. But does it only stop at battery damage? No! If the battery has a risk of exploding, there would be an equal risk for the phone to get damaged. What is the reason for this?

 

There is a risk due to the position of the battery. The battery is placed directly at the center of all mobile phones. There are several reasons for keeping it in the center, and one of those reasons is to protect the battery from water damage. If you have placed your mobile phone on the table and spill some water over it, it will not reach the battery. It is because the battery is at the center. Water can damage the lithium cells and destroy your battery. Now let’s come to the main point of discussion.

 

The battery is placed in an area where it will damage other components of the mobile phone if it explodes. If you keep charging it above 100 percent, the battery will explode, and the first thing it will damage will be the motherboard. The motherboard is a vital component of the cellphone as it carries out all the basic electronic functions, and it can be expensive to replace depending on the mobile phone. The next thing it will damage will be the screen. Most screens are expensive, and mobile phones of older generations have no second-hand screen available.

 

As a result, we can say that the battery level should not go above 100 percent because it can damage the mobile phone and cost you money to fix the damage, or you might even have to buy yourself another mobile phone.

 

It’s a general rule:

 

Every object made in this world has to follow a set of rules. These rules are made by the person who has manufactured a product. Most of the time, these rules are followed just because it is a natural phenomenon. The same is the case with battery percentage.

 

If we talk about percentages in months, they can go above 100 percent. I will explain this using an example. For instance, you come across a math question that says a book retailer achieved a profit of 200 percent. You do not have to be confused just by saying that percentages go only until 100 percent. You are right only of you mentioned the word battery with it. Although batteries do go above 100 percent, why is the max reading only till 100? The reason for that is that the software designed for mobile phones can read values only up to 100 percent. It means that even if the battery charge is 120 percent, the percentage showed on the screen will not be more than 100 percent.

What happens if you are charging your phone when it has reached 100 percent?

 

There are rules for using every single thing in this world, and if we go against those rules, we would do nothing but cause trouble for ourselves and the things around us. The same is the case with batteries. If the cellphone manufacturer has informed us to keep the battery percentage within a certain limit, we should keep it within the limit. If we go out of limits, we can damage the battery.

 

The cells will probably overheat, and it will reduce battery life. This happens mostly at night. I will explain this using an example so that you can have a better understanding of the concept. You must have seen people keeping their mobile phones overnight to charge them. During the night, the charge gets filled up to 100 percent, but since they are sleeping, the phone keeps charging even if it has reached 100 percent. As a result, cells may damage. Moreover, you must have heard stories about a house burning down because of cellphones. The reason for that is the blasting of mobile phones due to overcharging.

 

Moreover, the battery may be damaged permanently. Another interesting thing that can happen is that the battery may expand into a deflated balloon. But why does this happen? I will explain this using an example. Suppose you have a juice container, and that juice container can only take 500 milliliters of fluid. If you keep on filling the container, the box will expand, and the fluid will overflow. The same is the case with batteries. If you keep on charging, the cells will not be able to take it, and hence the battery will expand.

 

Moreover, if you keep on charging your cell phone, it will change your phone’s shape. If you keep on charging it even when it crosses 100 percent, the battery will expand. A time will come when the battery will expand so much that it will have so much space. After that, when the battery expands further, it will push other cell phone components outwards. When this happens, you will see a small separation between the screen and the body of the cellphone. If it expands too much, you might be able to see stretch marks on the plastic of your screen. In extreme cases, the expansion will be so much that the screen will crack, and you would not be able to use your phone anymore. As a result, you should avoid charging your mobile phone when it reaches 100 percent.

 

Moreover, the risks of fires due to the battery will increase. If you keep on charging, the cells inside will heat up. When they heat up, there will be a transfer of electrons. Sometimes when heat is involved, the transfer of electrons causes a spark. The chemical inside the batteries can ignite using those sparks, and hence a fire will be caused, and you can damage other components of the phone and the battery itself.

How to prevent your phone from charging further when it has reached 100 percent?

Set charging limit:

Most modern phones provide certain features that allow users to put a charging limit on their cellphones. When you click on that feature, you will be provided an option to set the battery limit. After that, you will select the battery limit. Keep the battery limit between 80 percent to 90 percent. Experts say that you should avoid full charge cycles from zero to hundred and charge in small intervals. When you set the charge limit, the phone will stop taking charge when it reaches that limit.

Third-party apps:

 

You can also use third-party apps to save your battery from getting damaged. These apps allow you to set a limit for your battery charging so that you do not exceed the charging limit set by you. Most of these apps are known as battery-saving apps. These battery-saving apps provide an additional feature to save overcharging of mobile phones and hence save the battery.

Battery charge threshold:

 

You might also use a battery threshold to save your battery from damage. You can set a battery threshold in your phone in which you will set a range of percentages. Most experts say that the battery threshold should be held between 50 percent to 90 percent. If this threshold is set, the charging will start automatically if the charge goes below 50 percent. If the charge reaches 90 percent, the charging will stop automatically to stop the battery from further damage:

Conclusion:

 

We can conclude that there are multiple reasons why battery charge does not go above 100 percent. The most obvious reason is that 100 percent is the limit and according to battery percentages’ universal calibration. Moreover, there are other harmful damages related to overhanging beyond 100 percent. Several techniques may be used to stop overcharging, and one of them is to set a charging limit on your phone.
