Fast charging technology is still progressing, just when most people think that “a mobile phone with a 4000 mAh battery in 30 minutes” is fast enough, this process is once again reduced:
It only takes 15 minutes now.
Just this week, four mobile phone manufacturers, including OPPO, vivo, iQOO, and realme, all promoted their new fast charging technologies.
Although everyone has certain differences in specifications and implementation principles, the goal of breaking through the three-digit power ceiling is consistent.
OPPO’s 125W super flash charge
Among them, vivo and iQOO took 120W, while OPPO and realme were 125W, which is equivalent to entering the era of “100W fast charging” overnight, which also brought a very amazing increase in charging speed. .
120W and 55W charging speed comparison of iQOO demo
In the comparative display given by iQOO, a mobile phone equipped with a 4000 mAh battery, under 120W fast charging, charged to 50% in 5 minutes, and completed from 0 to 15 in 15 minutes. 100% charging process.
The same battery size, but only using 55W fast charging mobile phone, only charged about 43% of the power in 15 minutes, the speed is half slower than the former.
One hundred watt fast charging is not only unique to the OV system. Earlier last year, Xiaobin President Lin Bin also demonstrated the 100W fast charging technology on Weibo and filled a 4000 mAh mobile phone in 17 minutes. .
Nubia Red Devils, Lenovo Rescue and other brands have also exposed 90W and 100W fast charging information.
Overall, this ultra-high specification fast charging technology has obviously been verified in the laboratory or upstream supply chain. Now it depends on which manufacturer can solve the mass production and commercial problems first, make up this last The “Football”.
But what will faster and faster charging bring? Can it solve our dissatisfaction with mobile phone battery life?
First, the mobile phone battery is not without breakthroughs, but the extra parts are used in other places
Mobile phone battery life is a common bottleneck faced by smartphones. If it weren’t because we had experienced the era of feature phones that charge once a week, probably no one would think that there is a problem with smartphones charging once a day.
It’s just that over the years, it has indeed become sparse and ordinary: before going to bed at night, we will find the charging cable at the head of the bed and plug it into the mobile phone, and then wake up and pick up the fully charged mobile phone to go to work And insisted on going home in the evening.
We have developed a habit from beginning to end, and mobile phone manufacturers have also chosen to maintain the status quo. They will not let the overall battery life be significantly lower than this standard, nor have they thought of making a significant improvement.
To a certain extent, today’s smartphones will stay where they are in terms of battery life, which is also affected by this “habit”.
Bigger screen, higher resolution, refresh rate, stronger processor performance, and faster network experience, these new technologies have brought users an improved experience, and are constantly compressing mobile phone battery life.
Instead of being a user, seeing that the battery has enough capacity, it will also subconsciously increase the frequency of using the mobile phone within the minimum goal of “endurance for one day”, or use the power consumption of games and videos more boldly Higher applications.

The result is that we think that the battery has not improved, but in fact, the battery may always be “unsatisfactory” for various mobile phone hardware upgrades year after year, and it can not satisfy our desire to use mobile phones.
So, Unless we can make the battery progress faster than the hardware upgrade, otherwise the status of “one charge per day”It will inevitably be maintained for a long time, and the short board of the mobile phone on the battery can only be compensated by the faster and faster charging technology.
Second, when the charging speed is fast enough, you may really “not feel”
The goal of mobile phone manufacturers to develop fast charging has been very clear: they hope to use shorter charging time to dilute the negative effects of one charging a day or even two charging a day.
So, even if the phone’s battery is used very quickly, it can at least save the charging time.
From the earliest 18W, 20W, and later to 30W, 44W and even 65W and other standards, the fast charging power of mobile phone manufacturers has increased year by year, and the charging time of our mobile phones has also been greatly shortened to the naked eye.

But what many people don’t expect is that when the charging time is getting shorter and shorter, and it starts to be infinitely close to the “instantaneous” state, it will gradually change our perception of charging. .
Take the case where I experienced OPPO Find X2 Pro before, for example, this phone supports 65W SuperVOOC 2.0 flash charge, and it can fully charge 4260 mAh battery in about 40 minutes.
But “the battery is completely used up and recharged” is actually the most extreme case. Most of the time, when the battery icon turns red, or when 20~30% of the power is left, we will start looking for recharging measures. .
The result doesn’t have to be full, but it’s more like 5~10 minutesCharge more in a short time.
OPPO 125W fast charge demo, from 0% to 41% in 5 minutes
If it is in accordance with OPPO’s current 65W standard, it takes about 22 minutes for Find X2 Pro to charge from 20% to 90%.
With the new 125W fast charge, it can charge a 4000 mAh cell phone from 0% to 41% in 5 minutes.
What is the concept of 5 minutes? Basically, it is the time for you to brush your teeth in the morning, drink a cup of coffee at work, or answer a work call. At the same time, the fast charging of 125W can make the mobile phone completely resurrected from the “red blood” state, supporting up to half a day. use.
This is the change that ultra-high-speed fast charging will bring-what it really improves is actually our charging efficiency in “fragmented time”.
With the support of 100 watts of power, this efficiency improvement is enough to obscure the concept of “charging time”. If it can be popularized, charging will also become an unburdened thing.
realme of 125W flash charging, can charge 33% of the electricity in 3 minutes
Before switching, it takes 1~2 hours to charge the battery once, so whenever we find that the mobile phone has only 50% battery power before going out, we will be upset and anxious.
But now, 5 minutes of charge and go, the charging time will no longer be limited to a large period of time, and charging has become a “negligible” matter in the use of mobile phones.
You don’t have to subconsciously plug in the charging cable before going to bed, nor do you need to maintain an awkward posture, dragging the phone while pulling the cable, just to catch half of the TV series before going to bed.
Perhaps this is the ideal charging, not a compromise of 5V/1A for thousands of years.
Three, the other end of the fast charging of 100 watts, we can’t ignore the endurance of the phone itself
After OV released their new fast charging technology, a friend asked me, after 15 minutes of charging the phone, can we hit the goal of 1 minute of charging?
Honestly, when fast charging first came out, no one expected that one day, we would see the commercial use and landing of 100W fast charging.
It’s just that with such a charging power, if you increase it further, the progress will be very limited.
After all, user perception also has a critical value. Under the current situation of “can charge nearly half of the power in 5 minutes”, will it continue to be shortened to 3 minutes, or even 1 minute, will it bring substantial changes? this is a problem.
Now manufacturers’ fast charging heads are beginning to enhance the compatibility with public agreements, but it is still difficult to unify the parts of private agreements.abel=”Image Remarks” class=”text-img-note”>
On the other hand, the problem of battery life still exists objectively, especially when the characteristics of 5G, 2K+ and high refresh rate screens are gradually popularized, I have clearly felt that the Android flagship machine’s battery life is “powerless” this year. , And always jump back and forth between “enough” and “not enough”.
This kind of “anxiety” about the endurance of the phone itself is difficult to make up for even the fastest charging speed. After all, no one always wants to see the “battery low” prompt box pops up frequently, and we can’t guarantee that every time the phone runs out of power, there is an accessory that can provide a fast charging of 100 watts.
After all, although fast charging is good, battery life is still just what most people need. Who can survive the life of a lithium battery is probably not an innovation, but a pioneering act.
