Original title: How much is it, test report: Samsung S22 + / ULTRA mobile phone 45W fast charge speed and 25W difference
IT Home February 21 news, according to GSmarena, Samsung Galaxy S22 series has finally brought improvements in charging speed.Two larger size models in the new Galaxy S22 series claim to provide 45W cable charging speed, while Samsung S22 Standard Edition retains 25W charging speed of its predecessors.
In the past few years, in terms of charging speed, the industry has been developing rapidly. Users bought a 65W-charging mid-end mobile phone from other mobile phone manufacturers, and the flagship mobile phone machines such as millet and Vivo have spanned 100W. But for Samsung, 45W is at least a progress, which seems to be much better than 25W.
However, the test report shows that the 45W effect of Samsung may only be present in the marketing material, and the difference between the 25W charging speed is not large.
The GSmarena Review Team uses three chargers to charge this mobile phone - Samsung original 45W and 25W charger, as well as third-party 65W PD charger to achieve good results. Note that these two Samsung chargers support power transmission (PD) and programmable power (PPS) standards, while third-party solutions are only PD certification.
We can see that Galaxy S22 + reaches 62% of the amount of electricity after 30 minutes of Samsung charger, while only 64% of the 45W charger. Samsung S22 Ultra uses 25W charger for 30 minutes after 30 minutes, with a 45W charger to reach 60%. Third-party 65W PD charger tries to fill the S22 Ultra's battery over 65% in the same time, which are within the error range.
Using a 45W charger, Samsung S22 + from 0% start fully charged for 1:01 hours, using a 25W charger for more than 1 minute. The use of 25W charger is fully charged from 0% from 0%, just 1:04 hours, and use 45W charger to complete the task for 5 minutes, ie 59 minutes. 65W PD third-party charger spent 1:02 hours.
What does this mean? Samsung's 45W charging rate claims may be completely misleading, even with the original Samsung charger pair, there is no real actual benefit than 25W solutions in terms of charging time.
Worse, in 2019, Samsung is exactly the same in Galaxy Note10 +. The company then gives up 45W charging on the Note20 Ultra. After the S22 + and S22 Ultra recovered this method, the report showed that it turned out the same mistakes.
This has two important revelations.First, if the charging speed is important to you, the Galaxy S22 series will be as disappointed like the previous Samsung flagship. Like the situation in the past two years, you need 1 hour to fully charge.
Second, if you finally want to buy Samsung S22 + and S22 Ultra, there is no need to spend $ 50 to purchase 45W Samsung charger. The 25W charger actually only 20 US dollars can play the same role.
At present, Samsung has not responded.
