The Charging Speed Showdown: A Comparative Analysis of Fast Charging Technologies
In today's fast-paced world, charging our devices quickly and efficiently is more important than ever. With so many smartphones on the market, each with its own unique fast charging technology, it can be overwhelming to decide which one to choose. In this article, we'll put several popular smartphones through a series of tests to see which one comes out on top in terms of charging speed.
First, let's take a look at the quick charge and adaptive charge technologies offered by different manufacturers. Quick charge and adaptive charge are two types of fast charging technologies that use stronger current to charge batteries more quickly. Both technologies have 5 volts and 4 amperes of power, resulting in an output of 20 watts. The major difference between these two technologies is that quick charge uses a fixed amount of current, while adaptive charge adjusts the current based on the battery's state of charge.
We tested three smartphones - the Oppo F9, the Poco F1, and the OnePlus 6 - using both quick charge and adaptive charge technologies. We charged each phone side-by-side to see which one charged faster. In the first 5 minutes, the OnePlus 6 took the lead, with a 10% charge. The Oppo F9 was close behind at 9%, while the Poco F1 trailed behind at 6%. By the 15-minute mark, the OnePlus 6 had taken an even larger lead, with a 29% charge. The Oppo F9 followed closely behind at 27%, while the Poco F1 and the Note 9 were further behind.
As the charging process continued, we saw that the OnePlus 6 and the Oppo F9 were still neck-and-neck, with the OnePlus 6 taking a slim lead in terms of charge percentage. However, it's worth noting that both phones are fast chargers, and their charging speeds are very similar. The Poco F1, on the other hand, was slightly behind the pack due to its larger battery.
At 45 minutes, the OnePlus 6 had reached an impressive 80% charge, while the Oppo F9 was close behind at 79%. The Note 9 and the Poco F1 trailed behind, with charges of 56% and 55%, respectively. As we continued to monitor the charging process, we saw that the charging speeds of all four phones had slowed down significantly.
In the end, it seemed like the Oppo F9's fast charge technology took the lead, while the OnePlus 6 and the Note 9 were close behind. However, when we calculated the average charging speed of each phone, we found that the results were not as clear-cut. The OnePlus 6 had an average charging speed of approximately 39 mA/min, while the Oppo F9 had a slightly faster average charging speed of 40 mA/min.
To give us a better understanding of the charging speeds of these phones, we also looked at how long it took each phone to charge from zero to 100%. The OnePlus 6 took 84 minutes to charge its 3.5mAh battery, resulting in an average charging speed of approximately 39 mA/min. The Oppo F9 had a slightly faster average charging speed of 40 mA/min, taking only 86 minutes to charge its 3500mAh battery.
Moving on to the Note 9 and the Poco F1, we found that they both took longer to charge their batteries. The Note 9 took 107 minutes to charge its 4500mAh battery, resulting in an average charging speed of approximately 37 mA/min. The Poco F1 trailed behind, taking a whopping 112 minutes to charge its 4000mAh battery.
Finally, we examined how the two charging faders of each phone perform during the second phase of charging - the final 20% charge. Both the Oppo F9 and the OnePlus 6 charged up to 80% in around 45 minutes but took an additional 40 minutes to get that last 20%. Similarly, the Note 9 and the Poco F1 also took around 65-70 minutes to reach 80%, before taking another 40 minutes to finish charging.
It's worth noting that while these tests were not particularly scientific, they do provide a general idea of how different fast charging technologies perform. The results show that both quick charge and adaptive charge can achieve similar charging speeds, with the Oppo F9's fast charge technology taking a slight lead in some instances.
However, it's also clear that there are other factors at play when it comes to charging speed, such as battery size and overall system efficiency. While the OnePlus 6 took an early lead in terms of charging speed, its smaller battery and faster system made up for this advantage over time.
Overall, these tests demonstrate that fast charging technologies can be comparable, but there are still some differences between them. The Oppo F9's fast charge technology emerged as a winner in certain aspects, while the OnePlus 6 and the Note 9 were close behind. But when it comes to overall charging speed, it's clear that each phone has its own strengths and weaknesses.
As we move forward in this era of rapid technological advancements, it will be interesting to see how these fast charging technologies continue to evolve and improve. Will new manufacturers emerge with even faster charging speeds? Only time will tell.
