As the saying goes, fish and bear's paws cannot have both. Everything has two sides. Although smart phones have become more and more powerful, they have many practical functions that have been ruthlessly cancelled or replaced by mobile phone manufacturers due to certain factors. , Such as: detachable battery, detachable memory card, 3.5mm universal headphone jack, radio, etc..., these very practical functions are now basically invisible on smart phones!

Next, we will focus on the advantages and disadvantages of removable batteries
As we all know, the removable battery means that the battery supports hot-swappable. Its biggest advantage is "charging in turn". As long as we prepare two batteries, a universal charger or a cradle charger, the mobile phone can never be charged. Of course, the premise is that there must be a plug-in board power supply. Two batteries are charged in turn, which can not only get rid of the trouble of the data cable, but also effectively reduce the potential safety hazards, because our batteries can be removed separately and placed away from flammable materials, far away from our resting place for charging, so that the battery fails and catches fire. Will not threaten our personal and property safety.
Another advantage is that our battery capacity can be infinitely expanded according to our needs. If one battery is not enough, buy two, and two are not enough to buy three. As long as the battery is of the same model, it can be used indefinitely. Change the battery for 5 seconds to solve it. In this way, you no longer have to worry about bulky power banks and annoying data cables on business trips and work. As long as you bring two more batteries, you can completely release the constraints!

Another advantage is that the same universal battery can be used repeatedly, which saves money and is environmentally friendly! For example, the previous Nokia mobile phones are like this. Every basic mobile phone of many models has a common battery.
