While it's a reasonable improvement over the 45W the company is using, it doesn't appear to be a huge leap forward for Samsung over other competitors.
Recently, Samsung has launched its most advanced smartphone generation to technology users. Galaxy S22 Series owns 3 different variants such as Galaxy S22, Galaxy S22+, and Galaxy S22 Ultra. In addition to the design lines with many changes or the features and performance are strongly upgraded, the Galaxy S22 Series generation is also improved by Samsung in fast charging speed to provide a more seamless usage experience.
Compared to previous lines, or most recently, the predecessor Galaxy S21 Series, Samsung has made improvements in upgrading the 45W fast charging system on the Galaxy S22 Series smartphone generation instead of keeping the 25W parameter.
However, not all 3 new variants are supported by Samsung 45W fast charging, but only 2 Galaxy S22 + and Galaxy S22 Ultra devices are slightly better than the Galaxy S22 when it only stop at a maximum of 25W. Although it has been improved, this is a significantly lower number than competitors such as Xiaomi, OPPO, or Realme when Chinese manufacturers have now raised their charging capacity to 65W or even at the threshold. 120W.
It can be said that Samsung seems to be implementing a 'slowly but surely' strategy when the Galaxy S22 Series generation owns its most powerful processor ever. With the 4nm process on Snapdragon 8 Gen 1 or Exynos 2200, these chips basically generate a large amount of heat, if these devices are supported with a super-fast charging capacity, it will make the battery easier. hot when used for a long time.
In addition, the use of a large capacity charger may cause the device's battery to quickly degrade due to high temperature during charging or even 'on fire'. For example, after the battery trip on the Galaxy Note7, causing the device to overheat and catch fire during charging, Samsung had to recall almost all products sold just a few months after launch.
Because of that, Samsung seems to have been more cautious in the development process and made strict spending decisions when deciding on the choice of battery and charging capacity in accordance with the performance of the device.
Besides, there are many opinions that the fast charging mode 'yes not' on the Samsung S22 Series does not bring much savings in both finance and time. More specifically, Youtuber SamMobile also has a real test video on the Galaxy S22+ showing that using a 45W charger only makes the device faster by a few minutes at most compared to 25W.
Next, at 30 minutes, S22+ brought back 70% battery with 45W fast charging, S22+ with 25W with only 65% battery.
It is a surprise when the S22+ after 45 minutes of charging, with the support of 25W and 45W fast charging, brings about the same results…even with 89% of the battery. This shows that the charging speed of both is almost equal.
Galaxy S22+ with 45W fast charging returned to the finish line earlier in 1 hour 15 seconds...
…but with the S22+ when it is charged with a capacity of 25W, it reaches the finish line 'much later' 1 minute 37 seconds.
In general, Samsung has made many improvements in various aspects of the Galaxy S22 Series generation, and the focus is on the fast charging speed supported on this device. According to practice, the difference between 25W and 45W is really not too different, users can still use the 25W fast charging system to charge on the Galaxy S22 Series. If you are a 'time billionaire' who can choose a 25W charger, if you are the 'nothing but condition' type of person, then 45W will be the right choice. So which fast charging capacity will suit you best?
