0 1 detachable batteries used to be the mainstream.
Mobile phones have been removable batteries for a long time. The earliest "mobile phone" came from Motorola, the radio giant completed the design of mobile phone with reference to portable radio products to some extent. Due to historical reasons, detachable batteries exist more as a "component" of mobile phones, which means that users can buy additional batteries to meet their daily battery life needs.
"Mobile" adopts detachable battery design.
The mainstream batteries at that time were mainly Ni-MH and Ni-Cr batteries. From the current point of view, these two batteries have low equivalent battery capacity and poor volume control, which makes "Big Brother" easily break through one catty. What really revolutionizes the design of mobile phones is that lithium batteries have successfully replaced nickel-hydrogen and nickel-chromium batteries. Small and rich lithium batteries make the design of mobile phones more possible.

At this stage, the design of lithium batteries can be "stuffed" into mobile phones. It can be said that this stage is an era of great prosperity of third-party batteries, and well-known battery brands such as Pinsheng and Scud all rise in this era.
How did the detachable battery decline?
With the increasingly fierce market competition, non-removable batteries have become the mainstream of the market. So why do detachable batteries gradually fade out of the mainstream of today's market?
Defy with detachable battery can still achieve a high level of dustproof and waterproof.
Many discussions about non-removable batteries in the market are untenable, such as "non-removable batteries can be dustproof and waterproof", but Motorola Defy is the dustproof and waterproof model of removable batteries, and Samsung has also produced many dustproof and waterproof models of removable batteries; "One-piece batteries can be packed into larger battery capacity." This statement is even more untenable. The real reason for miniaturization of detachable batteries is:
1, slim design, large battery capacity, replaceable battery, only choice. If the mobile phone body is designed as a replaceable battery, then the mobile phone body must be designed with a corresponding mechanical structure, and the mechanical structure often occupies a certain body space. If the design of mobile phone is thin and the battery capacity is large, then the priority of replaceable battery design needs to be given up. Today, battery technology has not been broken, and this theory continues to apply.
