Samsung Galaxy S22 Series Fast Charging

 

Samsung Galaxy S22 series has two quick charging performance configurations, namely S22 Ulrta, S22+ and S22, which support 45W super accelerated charge. According to Gsmarena test, although the power of Samsung 45W and 25W chargers is nearly doubled, the actual charging speed difference is not big, 30 minutes of charge is about 60%, 45W is mainly short-term peak power will be a little higher, after a long time charging power is close to 25W.

What are Samsung's original chargers?

Samsung has released two original chargers that match the 25W and 45W super accelerated charging technology. The 25W charger is EP-TA800, and the 45W charger is EP-TA845. Through the measurement of charging head network, it is found that these two chargers are usB-C port design, which is often referred to as fast charging port by consumers; Not only can it charge Samsung S22 phones, but it is also compatible with Apple iPhone quick charge, and it can also power light and thin laptops. Versatility is very strong, can be said to be a multi-purpose.

Samsung EP-TA800 maximum output power 25W, input voltage 100-240V~ 50/60Hz 0.7A, output support 5V3A, 9v2.77A two fixed voltage levels, 3.3-5.9V3A, 3.3-11v2.25A two sets of PPS voltage subset. By reading PDO messages with POWER-Z KT002 USB tester, it is found that EP-TA800 has two fixed voltage ranges of 5V3A and 9v2.77A, and two PPS voltage ranges of 3.3-5.9V3A and 3.3-11v2.75A. The maximum output power of Samsung EP-TA845 is 45W, the input voltage is 100-240V~ 50/60Hz 1.2A, and the output supports four fixed voltage ranges: 5V3A, 9v2.3a, 15V3A, and 20v2.25A. There are also 3.3-11V4.05A, 3.3-16V 2.8A, 3.3-21v2.1a PPS voltage subset. It is found that EP-TA845 has four fixed voltage ranges of 5V3A, 9v2.3a, 15V3A and 20v2.25a, and three PPS voltage ranges of 3.3-11V5A, 3.3-16v3a and 3.3-21v2.25 by reading PDO messages through POWER-Z KT002 USB tester.

What kind of charger can Samsung S22 series use?

Samsung is compatible with USB PD universal quick charging standard, which makes mobile phones have better compatibility and also makes Samsung dare to make the decision not to distribute chargers. As Samsung fast Charging is more flexible in the selection of accessories, users' experience will not be affected if they continue to use old accessories or purchase third-party accessories. Samsung mobile phone super accelerated charging technology relies on PPS voltage fine-tuning technology to achieve, handshake 11V voltage subset, according to the charger 11V PPS voltage subset maximum current profile matching the corresponding charging power. At present, third-party accessory manufacturers on the market have launched a large number of USB PD quick chargers. After 2021, most chargers on the market are also based on PD3.1 PPS version development.

Simply put, in order to achieve 25W super accelerated charging effect, the charger needs to have more than 11V2.75A PPS voltage subset, can choose 30W, 33W PD3.1 PPS chargers, they generally have 11V3A voltage range. If you want to achieve 45W super accelerated charging effect, the charger needs to have more than 11V4A PPS voltage subset. Most 100W PD3.1 PPS chargers have 11V5A voltage range, and a small part of 55W and 65W chargers have 11V5A voltage range, which requires careful screening by users.

PPS fast charging support

PPS (Programmable Power Supply) is a Power Supply type supported by USB PD3.0. It is a Power Supply that can realize voltage and current regulation by using USB PD protocol output. PPS specification integrates the current high voltage low current, low voltage high current two charging modes. In addition, PPS specification reduces the voltage adjustment amplitude to 20mV, which is one tenth of QC3.0 standard, and the voltage adjustment is more accurate.

PPS quick charge supports fine voltage regulation with step of 20mV, which provides the basis for the built-in charge pump quick charge of mobile phone. In the mobile phone review articles of charge-head network, it is often seen that the output voltage of the charger for the mobile phone is not fixed at 5V or 9V. In fact, the charger outputs two or four times the voltage of the phone's built-in battery, which is dynamically adjusted according to the battery voltage and the phone's needs. PPS quick charging can take advantage of low line loss of high voltage and small current to reduce power loss on data lines and use universal data lines. In addition, the high conversion efficiency of charge pump will input voltage and partial voltage, which can provide the experience of low voltage and large current charging for the battery without increasing the temperature rise of the phone. Samsung introduced PPS charging support inside the phone, as well as high efficiency charge pump quick charging, providing consumers with high efficiency and low temperature rise fast charging. After mobile phones are no longer equipped with chargers, consumers can easily buy a charger that supports PPS quick charge, providing the same charging experience for mobile phones as the original quick charge.
