With the development of science and technology, the charging speed of today's smartphones is getting faster and faster! It can even reach the point where the phone is full in 15 minutes. Although this technology solves the problem of mobile phone battery anxiety disorder very well, at the same time, many people are worried that such a fast charging speed will cause damage to the mobile phone? Is it safe?
1 Does fast charging harm the phone? Is it safe?
First of all, we need to know that for the safety of smart phone charging, the relevant state departments have formulated corresponding standards, and the charging technology of major mobile phone manufacturers must meet this national standard before it can be put into production. And whether it is a mobile phone manufacturer or an accessory brand, most of them will find a third-party testing company to do certification, such as Germany's Rheinland TUV certification, Apple MFi certification, etc.
The purpose of this type of certification is to ensure the quality and safety of the product, to determine that the product has a safety protection device to prevent overcharging, under the premise of normal use, even if the use of 150W mobile phone charging, is also safe.
At the same time, because the batteries used in today's smartphones are generally lithium-ion batteries, there are protective components on the battery to prevent the battery from being damaged. Under multiple protections, the damage of fast charging to mobile phones is negligible.
2The charging speed of the mobile phone depends on the charging head or the data cable?
Speaking of charging your phone, you still have to rely on the charger. So in mobile phone charging, which of the charging head and charging cable can affect its speed?
The charging head determines the size of the voltage and current, assuming that your mobile phone supports 5V/2.4A 12W charging, and the charging head you use is 5V/1A 5W, then the speed will naturally slow down when charging the mobile phone.
The data line is responsible for the transmission of current, which also plays a certain role. Because today mainly talks about the impact of fast charging on mobile phones, then it is assumed that mobile phones and charging heads support fast charging protocols, and data lines are just ordinary data lines, and do not support fast charging protocols, so the effect of fast charging cannot be achieved when charging.
Because the thickness of this data line (pipe) is small, the current (water flow) is naturally not large. At the same time, the length of the data line also has a certain impact on the charging speed, the longer the charge, the slower the shorter the charge, the faster the charge, but the general length on the market is 1 meter, and everyone can use this length.
3What do mobile phone fast charging need to pay attention to?
In fact, the damage to the battery caused by incorrect charging method is much greater than that caused by fast charging. The news such as the explosion of mobile phones that we often see on the Internet is actually not a problem with the mobile phone itself, but caused by the wrong charging method or the use of inferior chargers.
Common charging methods include only taking away the mobile phone after the phone is fully charged, and the charger has been plugged in the plug; the power of the mobile phone has been used until the red warning is used to charge; while charging while playing a large game, causing the mobile phone to be hot and other behaviors.
The reason why inferior chargers cause harm to mobile phones is because inferior chargers are no guaranteed products. It does not have the CCC logo, nor does it have clear information such as rated voltage, frequency, manufacturer name, model number, etc. At the same time, because there is no third-party certification, the charger does not have a safety protection device for overcharging, which is very unsafe when used.
Therefore, when we buy a charger, the most basic thing is to look for the CCC logo first, whether there is clear relevant information on the charging head, and choose a brand with third-party certification to buy.
Rather than worrying about the harm of fast charging to mobile phones, correct charging habits and high-quality chargers are more important, oh, after reading it, quickly throw away the inferior charger at home
Mobile phone charging can not be sloppy, your use habits are correct?
