In modern life, mobile phones have become an indispensable part of people's lives, and wireless communication technologies such as Bluetooth and NFC have given mobile phones more convenient functions.
These technologies provide us with the convenience of connecting external devices, fast data transfers, and making mobile payments, making our daily lives more convenient and efficient.
However, the problem that comes with it is battery life, which is a concern especially for those who need to use their phones for a long time.
Therefore, many people tend to turn off functions such as Bluetooth and NFC, thinking that they will consume a lot of power when turned on for a long time.
However, if the Bluetooth and NFC of the mobile phone are turned on for 24 hours, will it really cause the battery to continue to consume a lot of power?
In fact, the design principle of Bluetooth and NFC allows them to maintain relatively low energy consumption when turned on for a long time.
First: Bluetooth technology
Bluetooth is a short-range wireless communication technology used to establish a stable connection between devices, such as connecting headphones, speakers, or keyboards.
Bluetooth devices typically use Bluetooth Low Energy Bluetooth, which is designed to minimize energy consumption.
When a Bluetooth device is not connected to another device, it goes into a low-power mode and consumes only a tiny amount of power to maintain connection availability with other devices.
Therefore, even if you turn Bluetooth on but do not actively connect devices, the energy consumption of Bluetooth will remain relatively low.
Second: NFC technology
NFC (Near Field Communication) is another short-range communication technology commonly used for mobile payments and data transmission. Similar to Bluetooth, NFC is also designed with low power consumption.
When NFC establishes a connection between devices, it only takes a very short time to complete the communication process, and then it immediately goes into sleep mode and no longer consumes additional power.
This allows NFC to keep battery consumption low when turned on for long periods of time.
In addition, modern smartphones have been fully optimized at the hardware and software level to ensure efficient use of Bluetooth and NFC functions.
The phone system monitors the activity of these features and automatically turns them off when they are not needed to further reduce energy consumption.
This automated management allows Bluetooth and NFC to have little negative impact on battery life when not in use.
So, although Bluetooth and NFC functions are always on in mobile phones, their low-power design, short connection time, and optimized management of the operating system make them not significantly power hungry when turned on for a long time.
Therefore, everyone does not need to turn off these functions frequently, and can safely enjoy the convenience and efficiency they bring us.
Of course, you may feel that what you say is unfounded, but in fact, digital blogger @Changan Digital Jun has conducted experiments in this regard.
He continued to turn on Bluetooth and NFC functions for 24 hours, and found that Bluetooth power consumption was less than 0.01%, and NFC was only 0.02%, which was almost negligible.
In this experiment, Bluetooth and NFC functions did not actually have a significant effect on the phone battery when turned on for a long time.
Instead, they slightly increase battery consumption during the brief search for signals and devices at the moment of turning on and off.
Simply put, if you turn these features on and off every four or five hours, you can drain more battery than if you keep them on.
All in all, modern mobile phones have a variety of powerful features, including Bluetooth and NFC, which provide us with great convenience and quality of life improvement.
Therefore, there is no need to worry about the negative impact on battery life of turning on these functions for a long time, and we can enjoy the convenience they bring with peace of mind.
In today's world of continuous advancement, our mobile phones are smart enough to effectively manage battery consumption, making it easier for us to cope with the various needs of daily life.
