[Bestbuy618 cell phone channel]As people rely more and more on cell phones, the demand for cell phones with long battery life has grown exponentially. However, even if manufacturers strive to improve energy density and capacity by using low-power chip solutions, due to portability and technical constraints, battery life is still very close to its limit. When there is no way to make a significant improvement in battery life, faster charging speed becomes an unavoidable part of the experience.
In this technical context, cell phone fast charging technology is increasingly being used and favored by cell phone manufacturers, who have improved the charging speed of cell phones from the traditional 1-2 hours to become shorter, reducing the time cost of charging in exchange for convenience. Even if you go out with only half an hour of preparation time, the phone can be back to more than half of the blood, enough for temporary emergencies.
In the choice of specific fast-charging solutions, but the thinking of each family is not the same, and each family’s argument is also complicated, but the basic principle behind all the changes is well understood. We are all familiar with the power formula: P (power) = U (voltage) x I (current); if the phone’s battery is constant, then to improve charging speed, either increase the voltage, or increase the current, or both voltage and current; similarly, to slow down a pool of water, we fill the water either by increasing the speed of water flow from the faucet, or by changing to a larger faucet with more water.
The previous charging heads are 5V 0.5A or 5V 1A small hose slow water, and their ability to release water per unit is extremely limited. Now that 5V2A, 5V4A, 9V2A, and other specifications of the large water pipe fast water are being used, “full” battery capacity has more than doubled.
However, the voltage and current are not infinitely increaseable arbitrarily; increasing the voltage at the same time will generate more heat, and high current charging will also generate more heat. The lithium battery is relatively active and is most afraid of high temperatures and shock; if the heat rate exceeds the rate of heat dissipation, and there is no protection mechanism, the battery temperature will continue to rise, reducing life or even causing an explosion. As in a reservoir, if the water flow is too violent or too large, it will impact the pool wall to bring more pressure, and if the wall cannot withstand the pressure, it will rupture and collapse.
As a result, manufacturers are cautious in the selection of fast charging solutions, but now that the lithium battery can withstand the charge current value is increasing, fast charging development also has more space. Honor Magic2 uses safer 40W super fast charging, iPhone Xs Max uses 30W fast charging, and a plus 6T uses 20W Dash fast charging in newly released mainstream cell phones.
So, how efficient are various fast charging solutions? And are they safe to heat up during the charging process?Honor Magic2. Honor Magic2 is equipped with a 3500mAh battery, using a safer super fast charging (output 5V/2A or 9V/2A or 10V/4A MAX, the highest power reached 40W).
OnePlus 6T: The OnePlus 6T is powered by a 3700 mAh battery, which is equipped with Dash fast charging (5V 4A low voltage fast charging, 54=20W power). iPhone Xs Max from Apple The Apple iPhone Xs Max has a 3174 mAh battery, and this test employs the official 30W fast charging head.
Honor Magic2: The Honor Magic2 has a 3500mAh battery with safer super fast charging (output 5V/2A or 9V/2A or 10V/4A MAX, with a maximum power of 40W). OnePlus 6T: The OnePlus 6T has a 3700mAh battery with Dash fast charging (5V 4A low voltage fast charging, 5 x 4 = 20W power).
iPhone Xs Max from Apple The Apple iPhone Xs Max has a 3174mAh battery, and this test makes use of the official 30W fast charging head.// Honor Magic2, OnePlus 6T, and Apple iPhone Xs Max charging comparison test //
Honor Magic2, OnePlus 6T, and Apple iPhone Xs Max three cell phones were charged from 0% to 100%. Test conditions: All three phones were discharged to automatic shutdown; the chargers were also original; the charging tests were conducted on the same plug-in board; Test results: Honor Magic2 charging 10 minutes, the power from 0% to 31%, half an hour to charge 80% of the power, full with 58 minutes, the average charging efficiency.
The iPhone Xs Max charged for 10 minutes, the power from 0% to 21%, half an hour to charge into 55%, and 94 minutes to fully charge, with an average charging efficiency of 33.8 mAh/min. In summary, the least time consuming charging time from 0% to 100% is the safer super fast charging solution of Honor Magic2, which is the best among the three phones with the fastest charging efficiency of 60.3 mAh/min. It can ensure the phone’s charging efficiency while also allowing the phone to operate at a low heat conversion rate, providing users with a more dependable, safe, and simple-to-use experience. As a result, the super fast charging technology was sent to TUV Rheinland for independent testing and factory review, and it received the TÜV Rheinland 2.0 standard safety certification.
The Honor Magic2 Super Fast Charging solution can be considered one of the few fastest fast chargers on the market today that is also safe and efficient.
TÜV Rheinland Certification is a safety certification mark designed by TÜV Germany for component products to prevent personal injury and property damage caused by various hazards that may occur during the use of home appliances, mechanical products, and automotive products, such as electric shock or electrocution, excessive temperature, or fire. TÜV Mark certification means that the product has undergone independent testing and factory inspection by TÜV SÜD or TUV Rheinland, demonstrating that it meets the safety requirements of relevant European or international standards. It is possible to state that the safety of TÜV Rheinland-certified equipment or technology is guaranteed.
