6 important facts about cell phone batteries and how you can extend their life

Since most daily tasks are increasingly dependent on mobile phones, battery life has become an important issue for smartphone users. As a result, longer battery life has become one of the main features ordinary shoppers look for when choosing a screen size.

Battery life is more important than a powerful camera, according to a study by Kantar Q3 2019, and battery life and handling also affect the device's life.

Likewise, one of the reasons why fast chargers are so popular is to pay more attention to battery life. Since the phone battery only takes a full business day when used in a moderate way, you will need to charge it several times if you use it frequently. Here you can quickly recharge to get 50% energy in 10 minutes.

Fast charging functionality is becoming increasingly popular, especially for major phones, as almost all popular Samsung phones have this functionality, as is the case with Huawei, Google and OnePlus. This function is supported on mobile phones.

Since fast charging has become a global feature of mobile phones, many problems arise, such as: B: How does a high-capacity charger affect a mobile phone battery? Does fast charging impair the battery's energy storage capacity over time? Doesn't the charger charge for an extended period of time? How can I extend battery life?

Today, we will be reviewing some of the answers from researchers and engineers in the battery field about the effects of fast charging on the life of cell phone batteries:

1- The cell phone battery will not be replaced soon:

All mobile phones, as well as most electronic devices and electric vehicles, use rechargeable Li-ion batteries. Since battery technology has not changed for decades, it is difficult to manufacture more durable batteries.

Instead, most of the recent advances in battery life have been achieved by incorporating device power-saving features so that the operating system can manage charging and discharging more efficiently. ,

Likewise, the size of a cell phone battery is an obstacle to extending battery life, because when you compare a cell phone battery to an electric car battery, the cell phone has much less energy. For example: Tesla 3 battery battery capacity is 4000 times the capacity of iPhone 11 Pro Max, and this process is somewhat complicated, given that the phone battery unit is mA / h and the electric car battery unit is watt hour.

This is important because the higher the capacity of the battery, the more power saving tips to extend the life. For example: When the battery is charged, the potential difference (voltages) increases, which may lead to fatigue of the battery, especially during the last 20% of the charging process. To avoid this pressure, electric car manufacturers can only introduce new batteries that charge 80%. Because of this large battery capacity, electric vehicles can travel an acceptable distance while avoiding high-voltage loads. This can double the total car battery life.

Larger phones can be used all day, but are usually 100% charged. As a result, the battery maintains an acceptable time period between charges, but it also withstands high voltage differences. High blood pressure.

2- Fast charging does not damage the phone battery:

Conventional chargers can save 5 to 10 watts of power, while faster chargers can increase performance by eight times. For example: iPhone 11 Pro and iPhone Pro Max both include fast 18W chargers, while Galaxy Note 10 and Note 10 Plus include 25W chargers.

Even if the quick charger has been used for a long time, the phone battery will not be damaged unless there is a technical malfunction in the battery or charger.

The reason for this is that the batteries that support fast charging operate in two stages. The first stage adds a quick effort to an empty battery and saves about 50% to 70% of electricity in the first 10, 15 or 30 minutes, as the first charge stage can be quickly charged over a long period of time without any major negative impacts. In the second charging stage, the charging speed must be reduced and carefully managed, otherwise the charging process can damage the battery.

Therefore, the battery management system closely monitors the charging stage and reduces the charging speed in the second stage so that the battery can accept the charge and avoid problems, which is why 100% charging may take 10 minutes. If everything is handled properly, the damage is very rare as well.

3- The battery cannot be overcharged:

Annoying (overcharging) batteries always attract the attention of phone users. This is due to the fact that prolonged charging of the phone charges the battery with more than its capacity, which makes the battery unstable and shortens its life or increases its internal temperature. This could cause an explosion or fire.

According to experts, modern battery management systems are designed to interrupt charging if the charging rate reaches 100% before reaching the overcharge level.

Venkat Srinivasan, a battery researcher at Argonne National Laboratory, told Cnet: "If there is no problem with the battery circuit, you will not reach the overcharge level because it has built-in protection to prevent it."

Apple used an intelligent method in iOS 13 to fix this issue. If you leave your iPhone in the charger for a long day or long night, you can open the battery setting (improve charging) (charge the battery), monitor charging time and maintain a maximum charging rate of 80%. Only the battery can avoid the risk of a high voltage difference in the battery. Increase the fee to 100% before removing the phone from service. This setting is best for regular charging methods. Used because the iPhone battery won't get damaged for long when it is 100% charged.

4 - Do not put zero battery:

It may be necessary to completely disconnect the phone battery to reset the charging status. Unfortunately, modern phone batteries have evolved and this process is no longer necessary. Continuously discharging the battery can lead to chemical reactions that can shorten battery life over time.

To prevent the battery from completely discharging, the battery management system has a safety function that turns off the phone when the battery is low. If you want to extend battery life, connect the phone when 30% of battery power is reached (much higher than when the battery is low).

5-Overheating can damage the battery:

Warmth is the real enemy of the batteries. It is known that high temperatures may shorten battery life over time. Therefore, keep your phone out of direct sunlight, window openings and dashboards to avoid overheating, which may reduce battery efficiency over time, and in extreme cases, the battery can explode. This is rare, but it is a potential risk.

6- The batteries and cables compatible with the phone do not damage the battery:

If you do not use a damaged or fake charger and cable, the battery will not be damaged with a compatible cable and phone charger. However, the device may not charge as quickly as the original charger supplied with the device.

Some phones, for example B: Huawei and OnePlus phones use special chargers because the company is part of the department responsible for fast charging the charger. In order to use the fast charging function to the fullest extent, you must use the charger.

How can you continue to extend the life of your phone's battery?

To extend battery life, you can use common energy-saving tips, for example b. Reducing screen brightness, (Bluetooth) and (Wi-Fi) are not turned off. Define parameters to restrict use of background data and GPS monitoring used by the app.
