Snapdragon W5 Plus 1st generation promises long battery life for smart watches

Qualcomm introduced its latest chips for wearable gadgets, which will be launched under the names of Snapdragon W5 generation one and W5 Plus generation one. The 1st generation Snapdragon W5+ chip is a big step forward for Wear OS smartwatches in terms of performance and performance, and Qualcomm makes big claims about its long battery life.

The Snapdragon W5 Plus 1st generation chip is produced with the 4nm manufacturing process, which makes it a much more efficient chipset compared to what Qualcomm In the past few years, it has offered and converted. It is not bad to mention that the Snapdragon Wear 2100 and 3100 chips were both made with 28nm lithography. Meanwhile, the Snapdragon Wear 4100 chip is produced with a 12nm manufacturing process.

Qualcomm says that the Snapdragon W5 Plus 1st generation consumes between 30 and 60 percent less energy than the Snapdragon + Wear 4100 platform. In this regard, we see the biggest improvement in background notifications, which consume about 57% less energy than before, and VoLTE calls, which are the biggest source of smartwatch battery drain, with a 34% reduction in energy consumption in this new chip.

We should mention that the Snapdragon W5+ generation 1 chip uses four Cortex-A53 cores and one low-power Cortex M55 core with a frequency of 250 MHz. Also, Qualcomm has used the A702 graphics processor with a frequency of 1 GHz for this chip, which is a significant improvement compared to its previous generation. This new processor supports LPDRR4 RAM memory with a frequency of 2133 GHz and is also equipped with a new U55 machine learning unit. In this context and to show the effect of this chip on the battery life of wearable gadgets, we have conducted several tests with watches and batteries of different capacities, which we will discuss further.

In the first test, Qualcomm used a watch It has considered a modern smartphone with a 300 mAh battery. After conducting various tests on this smart watch, the battery life of this wearable gadget with the Wear 4100 + Snapdragon chip is estimated to be around 28 hours, but with the new Snapdragon W5 Plus 1st generation chip, this figure has increased to 43 hours.

The reason for using a 300 mAh battery in this test was that Generally, the average battery capacity of most smart watches is this amount. For example, the Fossil Gen 6 smartwatch has a 300 mAh battery and a 24-hour battery life. According to the statistics published by Qualcomm, this wearable gadget equipped with Snapdragon W5 Plus generation 1 will provide users with about 40 hours of battery life, and this is exactly what we expect from a 4nm lithography chip. For comparison, we should mention that the Galaxy Watch 4 has a 40-hour battery life with a 5nm Exynos chip.

Qualcomm also claims in the next test that if this new chip acts as the beating heart of a 4G battery-powered smartwatch. Considering 450 mAh, the battery life of this watch will be two days and approximately 54 hours. Meanwhile, the Snapdragon + Wear 4100 chip with the same battery capacity can provide users with only 36 hours of charging.

Finally, Qualcomm has conducted an experiment with a 4G sports smart watch equipped with a 600 mAh battery. Is. According to this report, this watch equipped with Snapdragon +Wear 4100 chip has a battery life of 48 hours. However, the smart watch equipped with the new Snapdragon W5 Plus 1st generation chip offers users up to 72 hours of charging time. If Qualcomm's claims are true, this amount of charging is extraordinary and has never been seen in any Wear OS smartwatch.

However, the only smartwatch we expect to come close to this amount of charging is the Galaxy Watch 5 Pro, which is yet to be released but is expected to launch with a 572 mAh battery. wearable It remains to be seen what other news will be published about this new chip in the coming days.
