Review the charging history of Samsung S series mobile phones

On the night of January 14, 2021, Samsung’s latest flagship S21 series was released, including the S21, S21+ and S21Ultra, which are still available in Tall, Grande and Venti sizes.
In terms of battery capacity, the three models are 4000mAh, 4800mAh and 5000mAh respectively, and the S21+ has a slight increase compared with last year.

Seems too conservative when it comes to charging, even…
A little backward, the three new phones all support 25W wired fast charge, 15W wireless fast charge and wireless reverse charge, while Samsung also actively responded to the environmental protection policy in the accessory, no longer with the charger and data cable.

The original Samsung S was unveiled in March 2010

In 2010, it is the world of physical button phone, the old mobile phone giant Nokia is still standing in the market.

Different from the past, in 2019, Samsung has fully launched three new models in the S10 series, namely the S10E, S10 and S10+. In the main performance aspects, the three new models are the same, but the differences in other configurations make the three new models separate.

In terms of battery capacity, the S10E body is the smallest, the battery capacity is only 3100mAh, support 15W fast charge;
But the S10’s battery capacity is only 3400mAh, also supports 15W fast charge;
The S10+, the largest, has a built-in 4100mAh battery capacity.
In terms of charging, the three models all support 15W fast charging.

In February 2020, Samsung S20 series was released, upgraded to 5G and supported 45W fast charging

Samsung skipped the S11 and went straight to the S20.
In February 2020, Samsung brought new Samsung phones, the S20, the S20+, and the S20Ultra, as scheduled.
Compared to the S10 series, it’s a big upgrade, with full 5G support and a new high in screen size, with the three models measuring 6.2 inches, 6.7 inches and 6.9 inches respectively.
Battery capacity: The S20 has a 4000mAh battery, while the S20+ has a 4500mAh battery.

In terms of charging, the S20 and S20+ are still fairly conservative, supporting only 25W of wired charging and 15W of wireless charging.
As for the extra-large S20Ultra, the battery capacity has increased to 5000mAh, and the charging power has also increased to 45W. However, the standard device is still a 25W quick-charge battery, and users need to buy a high-power charger to achieve 45W quick-charge.

In August 2020, Samsung Note20 was released, and the 45W fast charge was reduced to 25W fast charge

In August 2020, Samsung launched the Note20 series of new phones. At the launch, two models were introduced, namely Note20 and Note20Ultra.
All three models are powered by Qualcomm Snapdragon 865+ processor.

In terms of battery life, NOTE20 has a large built-in battery of 4300mAh, which supports 25W fast charging and wireless charging;
Note20Ultra has a large battery of 4500mAh, which also supports 25W wired fast charging and wireless charging.

In January 2021, Samsung’s S21 series was released, with 25W quick charge support for the whole series

On the evening of January 14, 2021, Samsung unveiled its new S21 series. The three models are the S21, S21+ and S21Ultra, with sizes of 6.2 inches, 6.7 inches and 6.8 inches respectively. The three models have a battery capacity of 4,000 mAh, 4,800 mAh and 5,0mAh respectively.

It’s worth noting that the S21 has a 4000mAh battery capacity, but only weighs 169G.
Charging aspects of the three models all support 25W wired fast charging and 15W wireless fast charging and reverse charging, and all do not come with a power adapter.


The overall upgrading trend of Samsung S series flagship phones is relatively gentle. It can basically be seen that the battery capacity increases with the updating of the model. The battery capacity of two Ultra models, including the latest S21Ultra, reaches 5,000mAh, which is the largest capacity segment among the S series models.

The quick charging power of the whole S series appears to be extremely cautious. Because the previous several models are too long ago to check the accurate quick charging power, because the battery can still be removed at that time, so it is speculated that the charging power of the mobile phone is about 3.5W and 5W.

With the S series update, the fast charging power that is supported is not updated at the same time. It can be seen that the fast charging power of 15W lasts for a long time.
Even the newly released S21 series only supports 25W fast charging, which is not updated or even retrograde from the charging point of view.

Samsung’s highest quick-charge power so far is the S20Ultra, released last year, which supports a 45W quick-charge.

Samsung’s mobile phone line currently has two flagship models, including the S series and the business-oriented Note.

The battery capacity growth of the entire Note series is at a regular level.

It basically increases the battery capacity as the model gets updated.

While charging is comparable to the S Series, the 15W Quick Charge lasted a long time, for reasons we all know.
The Note series currently supports the highest fast charging power of 45W, which is powered by Samsung’s Note10+.


Samsung, the king of the Android world, has not said much about the performance and screen quality of the phone, but it has been overly cautious when it comes to charging.
Due to the NOTE7 incident, the fast charging power of Samsung mobile phones has been stagnant for a long time. However, the fast charging power of models carried in the past two years has been slowly developed, but it seems to be just a flash in the pan…

The new S21 series has been released. Like last year, the S21, S21+ and S21Ultra have been released with a more conservative 25W quick charge, even the S21Ultra with the largest body size and the largest battery.
This is a step back from last year, when Samsung currently has a maximum power charge of 45W on its phones, both of which were released last year with the S20Ultra and Note10+.

S21 is no longer the standard charger and data cables, but for its quick charge effects is not too big, because samsung’s quick charge is based on the existing very high popularity of PPS of rapid development, plus a whole series of S21 support 25 w quick charge, so the market most support basic 3 a or 5 apps quick charge standard charger for S21 quick charge.
For users, there are more chargers to choose from. They do not have to be obsessed with non-original chargers. Of course, if they only look for the original charger in terms of charging, it will be said separately.
