4G and 5G, which technology consumes more battery?

4G is a high-speed mobile data connection technology, developed to replace the 3G platform, and has been widely used around the world for the past few years.

In addition to optimizing data transmission, communications, and 4G connectivity, it also offers a multitude of entertainment services as well as business applications such as vehicle monitoring, online support services. such as watching video entertainment, voice messages, video messages, video conferencing, and especially high-speed internet service .

However, technology is constantly evolving, even exceeding human use in many cases, 5G is an example. 5G is the next generation of mobile communications technology (after 4G generation), developed to bring humanity a truly wireless world, where we can access the Internet throughout. without encountering any barriers, limited in space and time. Not only that, 5G technology also has very high practical applicability in many important areas in the modern world such as self-driving cars, drones, virtual reality, and security. data, manufacturing, finance - banking .

The era of 5G is coming closer to us than ever before. Mankind is now holding 5G chips, modems and now potential devices and applications. However, so far, almost the main criteria to compare between 5G and 4G are still just speed. 5G is naturally faster than 4G and the difference in speed gap between these two connectivity standards is huge. We often have the funny saying that 'modernity damages electricity', so with the outstanding advantages mentioned above, the power consumption of 5G compared to 4G? More inferior to each other like? Especially when used on mobile devices such as tablets, smartphones or smart watches . devices are often particularly 'sensitive' about battery life.

You don't want to buy a 5G device right now because you're worried about how the technology will consume too much power on your device, which could seriously impact your usage time. Get rid of that thought! A new study by the international technology research group Signals Research Group (SRG) has shown that 5G equipment is in fact capable of providing better energy efficiency than 4G LTE models. in some situations.

1. 5G has begun to be rolled out in many countries, but does this technology pose a health risk to humans?

4G and 5G, which technology consumes more battery? Picture 3 5G gives transfer speeds superior to 4G, but energy efficiency isn't exactly that

Specifically, according to the team's calculations, both 5G and 4G may consume less power than the other connection depending on the bitrate and each specific application being used at a given time. device.

SRG testing was conducted in Minneapolis, Minnesota, one of the first areas where 5G technology was applied in the United States. The device used is Samsung Galaxy S10 5G (US version, CPU: Qualcomm Snapdragon 855, 5G modem: X50, similar configuration can also easily be found on the first generation 5G smartphone series), with the service Verizon's 5G and 4G networks.

Regarding testing tools, SRG used instrumentation from Accuver and Spirent. The testing took place at 5Mbps, 30Mbps and maximum bitrate respectively, continuously switching between 5G radio conditions and many 4G conditions, including carrier (carrier) technique. aggregation).

The results of the power consumption of these two connectivity standards are relatively 'mixed', but generally more positive for 5G. At the maximum possible bitrate (for Verizon networks that are within the 1Gbps range), 5G offers more energy efficiency than 4G LTE. It can also be said that 5G consumes less battery than 4G in case bitrate peaks.

However, for the lower bitrate (basic) test cases, 4G connectivity is much more energy efficient than 5G. This is probably because 5G uses more power when it is turned on and needs to be maintained for a longer period of time to transmit the same amount of data.

In other words, early 5G chips could produce vast amounts of data (such as a large file) with much better power efficiency than conventional 4G, but they consume a lot of power. more power when forced to transfer 'dripping' data over a long period of time, for example, when you are surfing the web.

In addition, early 5G devices can also connect (in parallel) between 4G and 5G, so optimizing the software will allow us to make a better choice of data transfer technology. I will use it.

SRG believes that the advantages and disadvantages of 5G's power usage characteristics are not so important because in fact, other factors in our phone usage habits - especially backlight, brightness screen - has a much bigger impact on battery life than a mobile chip.

So if you want to extend the battery life as well as the use time of 5G on the device, users should pay more attention to the habit of manipulating their phones. For example, adjust the screen brightness to a moderate level, turn off the mobile connection when not in use, or exit applications running in the background.

In general, the battery capacity of 4000 - 4500mAh on most phones that support 5G connectivity today is relatively enough to ensure you a normal working day, unless the device must Constantly handling heavy tasks, such as gaming.

Bottom line: 5G will consume less power than 4G at the highest bitrate, but more for basic tasks.
