Why is the removable battery mobile phone no longer used?
In previous mobile phones, the battery can be replaced. In order to ensure the battery life of the mobile phone, users often prepare multiple batteries in case of emergency. When a mobile phone is out of power, it can be fully resurrected by replacing it with a new battery. However, when smart phones became popular, the "all-in-one" mobile phone design made non-removable batteries mainstream:
This kind of remarks are indeed ridiculous, but this kind of remarks can let everyone know that the original removable battery design has been out of the public for so long that some people no longer know/forget that the original mobile phone battery is removable. Today we will take advantage of this popular message to talk to you about the choice between removable and non-removable batteries.
01. Removable batteries were once the mainstream
For a long time in the past, mobile phones have removable batteries. The earliest "Big Brother" came from Motorola. This radio giant used portable radio products to a certain extent to complete the design of mobile phones. For historical reasons, the removable battery is more of a "component" of the mobile phone, which means that users can purchase additional batteries to meet daily battery life needs.

At that time, the mainstream batteries were mainly nickel-metal hydride and nickel-cadmium batteries. From the current point of view, these two batteries have low equivalent battery capacity and poor volume control, allowing the "big brother" to easily break through a jin. What really revolutionizes the design of mobile phones is that lithium batteries have successfully replaced nickel-metal hydride and nickel-chromium batteries. The small size and abundant lithium batteries have made mobile phone designs more possibilities.

The appearance design of the lithium battery at this stage can be used as long as it can be "plugged" into the mobile phone. It can be said that this stage is the era of great prosperity of third-party batteries, and well-known battery brands such as Pinsheng and Scud have risen in this era.
02. How did the detachable battery decline?
With the increasingly fierce market competition, non-removable batteries have become the mainstream of the market. So why are removable batteries gradually declining to become a non-mainstream in today's market?
The Defy with removable battery can still achieve a high level of dust and water resistance
Many discussions on non-removable batteries on the market are untenable, such as "non-removable batteries can be dust-proof and waterproof", but Motorola Defy is a dust-proof and waterproof model with removable batteries. Samsung has also produced many Dust-proof and waterproof models with disassembled batteries; "The integrated battery can be squeezed into a larger battery capacity." This statement is even more untenable. The real reason for the decline of the removable battery is:
1. The mobile phone can only choose two of the thin and light design, large battery capacity and replaceable battery. If the mobile phone body has a replaceable battery design, then the mobile phone body must be designed with a corresponding mechanical structure, and the mechanical structure often occupies a certain amount of body space. If in order to ensure that the mobile phone has a slim design and large battery capacity, then The priority of battery replacement design needs to be discarded. To date, battery technology has not yet broken through, and this theory continues to apply.
iPhone is the leader in non-removable battery design
2. The design of the integrated body conflicts with the design of the detachable battery. Samsung's early Android models are designed with removable batteries. At that time, Samsung's mobile phones achieved a comprehensive balance, both in terms of body weight and battery capacity. But the future development direction of mobile phones is "integration."
Removable batteries will seriously damage the industrial beauty brought by "integrated" mobile phones, especially when metal and glass materials are added to the appearance of the mobile phone, it is more difficult to balance the cost of the detachable structure and the weight of the body.
03. Why do users have fewer complaints about non-removable batteries?
Where Apple leads the design trend of non-removable models, users have a deep resentment for non-removable batteries. The main complaints are: small battery capacity, poor battery life, and long charging time. The objective reason for users to reduce their complaints about the integrated body design is the advancement of fast charging technology.
Fast charging technology solves the anxiety of battery life under the design of non-removable battery
Fast charging reduces the time it takes for a mobile phone to fully charge the battery from two hours to less than 30 minutes. The new wireless fast charging technology allows mobile phones to be charged more quickly, reducing user complaints about battery life. In addition, innovations have been made in supporting charging services, such as rental power banks that meet users' demand for mobile phone power when they go out. It can be said that the status of non-removable batteries is hard to shake.
Summarize
Consumers' consumption concept is constantly changing. With the comprehensive development of various infrastructures surrounding "non-removable batteries", it is not important whether the battery can be removed, but this does not mean that the design of removable batteries has completely disappeared. Smart phones for niche markets, such as niche phones that focus on outdoor three defenses, will use "removable batteries" as an important selling point. Looking back, who would have thought that the detachable battery design that once flourished would disappear?
