In 2020, Samsung unexpectedly prepared a new machine with removable battery. On June 1, it was reported that SamMobile, Samsung's semi official website, revealed a picture of a battery. This EB-BA013ABY battery is said to be used on Samsung mobile phones with a capacity of 3000mAh and a model of SM-A013F.

According to the model name, this phone should belong to Samsung Galaxy A series.

SamMobile pointed out that this may be an Android One device (translation: an ultra low configuration Android phone sold abroad, running a thin system and app), which will be sold in the Asian and European markets, with two versions of 16GB and 32GB (really in line with the positioning of Android One...).

In 2016, even the LG V20 canceled the design of removable rear cover, and no normal models of major manufacturers used this traditional design anymore. In the eyes of modern people who are used to it, removable batteries have become a different kind. The design of "integrated body, non detachable battery" that you see now is the most powerful promoter of the iPhone (this is the case with the original iPhone, which was also blown away by players' complaints).

The advantage of detachable battery is naturally that the power is low. If there is no power, replace the battery directly, which is faster than any quick charge. In the face of this design, battery life and fast charging seem to be less important. But the disadvantage is that the body will become thicker, and the battery capacity will shrink (the battery compartment and the removable back cover occupy space), and the power on/off operation is not very convenient. The advantages and disadvantages of the integrated fuselage design are just the opposite.

When the industry began to rush towards the detachable design, people were also reluctant to give up, just like the "extremely advanced 3.5mm headphone interface", but the great wheel of the times was still rolling forward without nostalgia. I still like Samsung's renaissance retro operation. After all, only by allowing all kinds of brain holes to blossom can we meet the life and entertainment needs of different revolutionary masses. All mobile phones are not fun if they look the same.
