What is the gap between 25W and 45W? How about PPS compatibility? Samsung note10 + charging evaluation

In August 2019, Samsung released the note10 series of flagship mobile phones, which are divided into two versions: note10 and note10 +. The charging performance is also divided into two parameters: note10 supports 25W accelerated charging, and note10 + supports 45W accelerated charging. Samsung has finally caught up with the market in high-power fast charging.

1、 25W charger as standard

Both note10 and note10 + are equipped with a 25W charger. In 2019, the third-party chargers on sale in the market can not activate Samsung 45W accelerated charging. In order to obtain faster charging speed, users can only buy Samsung original 45W charger (ep-ta845).

The 25W charger model of note10 + configuration is ep-ta800, which supports two fixed voltage outputs of 5v3a / 9v2.77a, and has two groups of PPS: 3.3-5.9v3a / 3.3-11v 2.25A.

2、 Compatibility of commercial third party PPS chargers

After more than half a year, there are more and more PPS chargers on the market, and the supporting current is higher and higher. Xiaobian has selected some of the most popular PPS chargers at present. Let's test the compatibility of note10 + with PPS.

1. 3A PPS charger

Samsung original ep-ta800 25W charger with 3A PPS, charging power for note10 + is 9.22v 2.64A 24.41w, and 25W to accelerate charging.

Bess bs-c915 65W 2c1a Gan charger with 3A PPS, charging power for note10 + is 9.30v 2.91a 27.10w, and 25W to accelerate charging.

Byz fc83c 65W 2c1a Gan charger with 3A PPS, charging power for note10 + is 9.32v 3.11a 29.03w, and 25W to accelerate charging.

2. 3A + PPS charger

Xiaomi ad653 65W 2a1c charger with encrypted 4A PPS, charging power for note10 + is 9.34v 3.85a 36.05w, and 45W to accelerate charging.

Xiaomi ad65g 65W Gan charger has encrypted 5A PPS, charging power for note10 + is 9.26v 3.75a 34.82w, and 45W to accelerate charging.

Nubia nb-a1150a-usba-c 55W charger with 5A PPS, charging power for note10 + is 9.53v 3.91a 37.32w, and 45W to accelerate charging.

Black Shark mdy-11-eb 65W magic modified PD charger with encryption 6A PPS, charging power of note10 + is 8.83v 1.63a 14.42w, handshake 18W PD charging, PPS can not be recognized.

Make the test data into a table, Samsung note10's support for PPS is still very good, public broadcast PPS all normal handshake, two kinds of encrypted PPS millet charger can also handshake and reach the maximum power, black shark 65W magic change a port's encrypted PPS failed to correctly identify.

The power data is made into a bar chart. The top three chargers shake hands for 45W accelerated charging, with the power between 34W and 37W. The last three chargers shake hands for 25W accelerated charging, with the power between 24W and 29w. Those who fail to shake hands for PPS are charged by PD, with the power of 14W.

3、 Comparison of 25W and 45W speed

The test environment temperature is 25 ℃. The 3A PPS charger selects the Bess Gan charger as the test sample, and the 5A PPS charger selects the Nubia 55W charger as the test sample.

Within the first 7 minutes, the note10 + of 3A PPS has been trying to sprint to higher power, but limited by the 3A peak, the power platform is about 25W. The 5A PPS 34W high-power platform maintained for 6 minutes, then the temperature rise power fluctuation of the mobile phone was repeatedly adjusted to 10W, and after 15 minutes, the power was in the 25W power platform as the 3A PPS charger.

The charging power was made into a comparison chart of charging speed percentage. In 10 minutes, 3A PPS charger charged 24.1%, 5A PPS charger charged 28.3%, and the difference was 4.2%. In 20 minutes, the 3A PPS charger charged 47.3%, the 5A PPS charger charged 51.9%, and the difference was 4.6%. In 30 minutes, 3A PPS charger charged 68.9%, 5A PPS charger charged 72.7%, the difference was 3.8%. In terms of total time consumption, both chargers take 1 hour and 19 minutes.

Summary of charging head network:

This is the end of note10 + charging evaluation. Note10 + supports 25W and 45W accelerated charging, which is a fast charging protocol based on pd3.0 PPS. The charger of 3A PPS can accelerate charging with 10 + 25W handshake note, and the measured charging power is about 25W; The 4A / 5A PPS charger can accelerate the charging with note 10 + 45W, and the measured charging power is about 35W.

Whether it is 25W or 45W, there is no obvious difference in the whole charging time. Within 20 minutes before charging, the charging speed of 45W will be about 4% faster than that of 25W. After the temperature rise of the mobile phone, the charging power of 25W and 45W will maintain at 25W platform, and the rising speed of power is basically the same.

For users who pursue speed, choosing a 5A PPS charger or directly purchasing Samsung original 45W charger (ep-ta845) will get a faster fragmented charging experience. The 25W / 45W speed of users who have been waiting and waiting is not half as exaggerated as you think. At present, the 5A PPS charger is about 100 yuan, which can be selected according to their own needs.
