In thepast, the biggest problem faced by phone users is that the battery life is too weak. Once the power is used up, it will take a long time to charge. Now, a new charging technology lets us change: quick charging technology for phone. The biggest role of this technology is to make the smartphone battery fully charged in a shorter time.
Part1: The principle of fast charging technology
Each smartphone is equipped with are chargeable lithium-ion battery, and the smartphone battery is charged when the current is passed. Experiments have shown that larger currents and higher voltages can charge the battery faster. It increases the current and voltage to achieve fast charging. However, the capacity of the battery is limited, and quick charging battery charger need to prevent dangerous peaks in current.
Part2: Classification of Phone Fast Charging Technology
1. phone quick charge is mainly divided into two categories: high-voltage and low-voltage fast charging technology.
2. The difference between high-voltage and low-voltage fast charging technology
High-voltage fast charging technology supports up to 9V/2A or 12V/2A. The main representatives are Qualcomm quick charge and MediaTek PEP. The high-voltage fast-charger technology of the Micro USB is compatible with the data line, if there is a specific power manager and identification chip. The disadvantage is that the full-speed fast charging technology generates a higher heat.
The cost of low-voltage fast charging technology is higher than that of high-voltage fast charging technology. The low-voltage fast charging technology solution needs to carry a larger input/output current, so the USB interface and charging device need to be modified. Using specially-built chargers, data cables and charging modules inside the mobile phone, it is simply transforming the hardware from start to finish; although the cost is high, but the power is greatly enhanced, the heat can also be well controlled, and the side is filled.Play games will not affect the charging efficiency of the phone.
Part3: How to Choose Fast Charger for iPhone 8x/Samsung
1. Best Fast Charger Options for iPhone
Apple's iPhone X, Apple 8, and iPhone 8 Plus support fast charging wireless charger. However, to achieve it, you must pay for new accessories, because Apple does not offer a fast charger, you need to buy a USB-PD-enabled power supply. Adapter and cable for fast chargers for iPhone X, iPhone 8 and iPhone 8 Plus:
- Apple 29W, 61W or 87W USB - C power adapter
- USB-C power adapter that supports USB power transfer (USB-PD)
2. How to Purchase Fast Charging Power Kit for Samsung
The Samsung Galaxy S9 and Note 8 are compatible with Fast Charge 2.0, and the fast charging theory peak for Samsung phones is 9V / 2A (18W). Most fast charging devices supporting the fast charging of the Samsung Galaxy S9 and Note 8. It is recommended to choose a branded fast charger.
Part4:How to Identify Fast Charging Cable?
Charging speed is depending on whether the charging socket has a large current and whether the mobile phone supports fast charging. If the phone does not support fast charging, you can buy a fast charging plug, the same can be used, but the charging speed no change. The adapter cable that does not support fast charging is a five-core cable; the adapter that supports fast charging not only has a large output power, but the data cable is seven cores or more. Relatively speaking, it is mainly whether the mobile phone supports the fast charge protocol and supported the fast charge.
Part5:Will Fast Charging Technology Affect the Battery Life?
This is a very important issue. Fast charging technology can reduce waiting time, but is it safe?
1. For mobile phone that support fast charging
For mobile phones that support fast charging technology, charging the phone with the correct fast charger(supporting your mobile fast charging protocol) is the safe, and it won't affect your phone battery.
2. The phone does not support fast charging
If your phone does not support fast charging, I don't recommend using a fast charger because it will not only can't speed up your phone's charging, but also affect your phone's charging control circuitry and shorten battery life.
The Bottom Line:
In my opinion, fast-charging battery technology is a good technology, and all mobile phones can be fully charged in minutes instead of hours. But now, only a few models support fast charging technology and you need to buy a stable wireless fast charger to your phone.
