What is the battery capacity? Is it a determining factor in usage time?

With the increasing demand for use today, the time to use a device such as a phone is a factor that makes users consider before deciding to buy. So let’s find out with Tnhelearning.edu.vn what is the battery capacity? Is it a determining factor in the time of use and the issues surrounding it!

What is the battery capacity?

“Battery capacity” is a term that describes a battery’s ability to store an electrical charge, as determined by the mass of active material inside it. Tested by the manufacturer, measured and given the maximum parameters the battery can be stored on the equipped products.

For example, a battery with a capacity of 1000 mAh can provide a current of 1000 mA (1A) to the device for one hour of use. This parameter helps you to partly determine the strength and weakness of the batteries, the larger the mAh , the longer the usage time on the device will be.

Unit of measurement of battery capacity

“mAh” (miliAmpe-Hour) is currently a unit of measurement of battery capacity that is widely used for devices such as smartphones and tablets. The higher the mAh of the device, the longer it will last.

​

On some products that are also measured in units of Wh , the difference between the two is that Wh represents active power (consumed or generated) in 1 hour, and mAh is a unit to measure active intensity. for 1 hour on one device.

Size restrictions

Increasing the battery capacity on the device means having to increase the battery size, which affects the current trend of thin and light design. Trying to cram a high-capacity battery into a thin and light product will limit the space for hardware upgrades.

Currently, this issue is being paid great attention by manufacturers to balance design elements, usage time and performance on the machine.

Batteries about batteries

Is continuing to charge when fully charged harmful to the device?

On today’s electronic devices, there is a smart battery management system built-in, which automatically disconnects the charger when the device reaches the 100% limit to minimize the situation of the battery being overcharged and causing battery bottles.

Experts also recommend that users should unplug the charger when the device reaches 80% – 90% to limit unexpected risks such as unstable current, ambient temperature affecting the device, ensuring safety. for the device and the user.

Should the power be used up to 0% before charging?

This is absolutely not recommended, when the battery capacity drops to 0%, it will affect the battery management system, displaying the battery percentage that is not stable. Users should charge the device when the device has 20% – 30% battery left to the device to operate in the most stable way.

Using the wrong charger as the supplier affects the device?

For chargers and charging cables of reputable brands, you are completely assured when using. But for fake chargers, reputable manufacturers or the wrong charging cable parameters will make the current inside the machine unstable, leading to a battery error, fast battery life. and can also lead to fire and explosion.

Is battery capacity a determining factor in usage time?

With the trend of developing smart battery management features, integrating power-saving technologies on the chip or using the latest screen technologies to provide more optimal usage time. So battery capacity is no longer a determining factor in usage time like it used to be.

For example: If we bring out 2 devices with the same mAh capacity, have the same tasks but it is not known whether they operate with the same voltage V, have the same screen type, chipset or not. completely incorrect.

Therefore, before deciding to buy a device with a long use time, we are not only interested in battery capacity (mAh) but also have to pay attention to factors such as screen, processor, other technologies. battery saving and intended use.

Tips to prolong the use time

Equipping a backup charger is a popular solution for many people, being able to charge and use it without fear of interrupting work, avoiding the case of having to use a direct power source that affects the machine and causes danger. dangerous for yourself.

In addition, users can also turn on the battery saving function, reduce the screen brightness or can turn on the airplane mode to bring the longest operating time possible.
