Charging speeds in smartphones are increasing day by day. Companies such as Oppo, Huawei, Apple are in a race to offer users the fastest charging times. Even though this competition is still in the testing phase, it brings speeds up to 240W and charging the phone to a full charge in 9 minutes. So, do high charging speeds on smartphones reduce the life of the battery? If you cool the phone enough, can you charge it at the high power you want without getting hot?
Is fast charging killing your phone’s battery?
According to Mcdodo Turkey General Manager Mehmet Uçurum, although we do not know the results yet, the solutions developed using all the blessings of technology; for now, it seems like it will allow you to use your battery for long periods without damaging it.
With smartphones becoming the most important tool of our lives, the high performance and charging times of these devices occupy our agenda. Considering that one of the most important topics that technology companies work on is the charging times of computers and phones, it is not surprising that the consumer is so sensitive to this issue.
Mcdodo charging stand review!
We reviewed Mcdodo’s 4-in-1 multifunctional desktop wireless charger. What does Mcdodo charging stand offer?
All companies are in a race to develop the best technologies, especially to charge smartphones fast and keep that charge longer. It is our most natural right to want to charge our phone in the fastest way, even today, when we are racing against time. That’s why the world’s largest phone manufacturers continue to offer adapters that offer higher-speed charging every day.
While world giants such as Apple, Huawei, Oppo are racing fast charges up to 240W, the biggest question in users’ minds is: “Wouldn’t such high-speed charging cause my phone to overheat and damage the battery?”
We went from 5W to 240W in a few years
providing information on the subject Mehmet Uçurum, General Manager of Mcdodo TurkeyStating that, especially in recent months, a new brand has started to issue fast charging from another and the fast charging market is growing, he said, “The 5W adapters that came out of the iPhone boxes a few years ago were quite enough for all of us. It was fully charged in 2.5 hours.
Then the 18W charging that Pixel rolled out was super fast charging for all of us. Then the iPhone went to 20W charging. Then we suddenly experienced 30, 45, 65, 80W phone chargers released by both Apple and other brands in a few years. Today, the Xiaomi 12 Pro comes with a 120W charging adapter and charges the phone to 100 percent in 17 minutes. A few weeks ago, Oppo demoed 240W charging and reached 100 percent charge in just 9 minutes in this trial. “We’re seeing speeds that we couldn’t have imagined a few years ago.”
Users think their phones will be damaged
At this point, the first question that comes to the mind of all smartphone users is, “How can such a fast high charge charge such small batteries without damaging them?” Uçurum said: “As a matter of fact, users cannot believe that charging at such high speeds cannot be done without damaging such small phones, and they question this situation.
The thing that comes to mind most is that it can cause a serious heating problem on the phone. They don’t universally believe it will charge that fast without damaging the battery. But if these concerns are true, why are so many brands, the entire industry investing millions of dollars every day to produce higher-speed charging?”
Reminding that the battery hardware of smartphone batteries comes into play at this point, Uçurum explained the general charging process as follows: “Currently, the batteries of smartphones are lithium ion or lithium polymer. The battery has a positive and negative side. When the phone is charging, the flow is from the negative side of the battery to the positive side. Ions collect there. When the charge is finished and plugged into the charge, the ions flow from the positive side to the negative and collect there.
The charging battery is like a kind of sponge. As they get closer to being fully charged, they can no longer absorb current at such a high rate, and some losses begin to occur. This loss of current causes the battery to heat up. In short, the charging process is actually a curve, not a straight line. These current rates, which we witness increasing every day, are not actually a constant charge rate, but the point where the charge peaks.”
Current showing digital cables
Adding that we can now monitor the amount of current entering your phone and how it changes according to the saturation rate of the battery, with the current indicator digital charging cables produced by Mcdodo, Uçurum said: which is quite natural. But in this whole cycle, it is heating, not natural wear, that damages the battery. However, the ions in the battery are very sensitive and resistant to heating.
Therefore, when it comes to batteries, the aim is to minimize heating in order to prevent the battery from wearing out faster than normal. Since faster charging brings with it faster heating, it would be a natural inference to think that the accelerating charges also damage your phone.”
Technologies developed against heating
“One of the most important issues that technology companies have been working on in recent years has been to offer the fastest possible charge with the lowest possible battery temperature.
Uçurum said, “The heat protection technologies of high-speed charging batteries, which are now being released one after the other by big phone companies, largely eliminates this problem,” said Uçurum. parallel charging. In this method, you divide the battery into two different cells and divide the incoming current into two, and you sing like 2 different batteries.
Thus, the battery receives the entire current divided by 2. Therefore, you can do the high charge without warming up. With the increase in charging speeds, most of the smartphones produced in recent years come with a ‘cooler’ hardware that prevents heating during charging. We’ve been seeing this for a few years, especially in gaming phones.”
Target 80 percent battery health
But do all these methods work? Is the solution to this problem that simple? If you cool the phone enough, can you charge it at the high power you want without getting hot? Uçurum gives the answer to these questions as follows: “Whatever you do will you damage the battery of your phone? There is a standard for this in the telephone industry. 80 percent battery health after 800 charges. This equates to about 2 years.
In other words, the target in a healthy battery is 80 percent battery health after 2 years. Currently, in laboratory tests on high-speed charges, it has been proven that the battery health is 80 percent after 800 or even 1,600 fast-charge recharges for some brands. Even though such high-speed charges have just entered our lives, scientific tests prove that they do not harm the battery.”
Stating that the industry continues to do better in the field of fast charging, and Gallium nitrate chargers, one of these innovations, offer much higher charging speed with much smaller and lighter sizes, Uçurum added that Mcdodo’s many different products in this field, meet the different needs of users. He says he continues to give.
