The battery is the most basic configuration for a mobile phone. When consumers talk about mobile phone batteries , the first thing to think about is the size of the capacity, because it is related to the standby capacity of the mobile phone, but in addition to the size of the capacity, in recent years. The design of the battery has played a new trick, that is, "built-in battery."

Too far away, we don't go back. Let's just say that Apple's iPhone series phones, from the first generation of Apple iPhones to the current fifth-generation Apple iPhone 4S, all use the built-in battery design, that is, when your iPhone When there is no power, you can't replace it with a spare battery like a traditional mobile phone.

Then in 2010, the Nokia N8 also adopted the design of the built-in battery. In this year, the Nokia N9 and Nokia 800 also adopted the design of the built-in battery. The Motorola Droid RAZR just released also uses the built-in battery design, built-in battery in the Apple iPhone. Under the guidance of the seemingly popular trend, then what are the advantages of the built-in battery?

Advantages: Thinner and more unique machine design

Mobile phones with built-in batteries generally do not have a "removable back cover". SIM cards, SD cards, etc. are all designed on the side of the fuselage. Since the back cover does not need to be detachable, it is not considered convenient for users when designing the motherboard. In this case, the position of the battery and the position of other components will change accordingly, so that a more reasonable layout of the motherboard can be designed.

The layout of the motherboard may not have substantial contact with the consumer, but after designing the motherboard based on this, it affects the design of the appearance of the fuselage, and the designer can design a more fashionable and more beautiful appearance. For example, the "ultra-thin" that consumers like very much.

Apple iPhone 4 is a very successful example, many of its users and "quasi" users are unable to resist such avant-garde, ultra-thin body, while the Motorola Droid RAZR body thickness is only 7.1 mm, than The thinnest Samsung I9100 was 1.39 mm thin. If you don't have a built-in battery design, I am afraid it is very difficult.

Disadvantages: It is not convenient to replace the battery

The disadvantage of the built-in battery is precisely its advantage. It is said that each has its own advantages and disadvantages. The replacement of the battery that the author refers to is inconvenient and contains two situations. The first one is that the mobile phone has no power. Presumably, this situation is the most troublesome. Because the battery cannot be replaced, the user can only miss the phone, but as a mobile digital product, it is necessary to keep the power at all times. Obviously contrary to the "portable" use concept.

The second is that the battery is a consumable. After a period of use, there will be a "virtual power" situation, resulting in a decrease in standby capacity. According to the traditional usage habit, the user can purchase a battery, but due to the built-in The disassembly of the battery phone is complicated, and it is impossible for ordinary users to replace it themselves. Therefore, only the replacement of the after-sales service point or the maintenance point will increase the cost and time cost accordingly.

The built-in battery replacement is not easy. At present, there are not many mobile phones with built-in batteries, but first-line manufacturers such as Apple, Nokia, Motorola, and Samsung all have mobile phone products with built-in batteries. I have to admit that Apple iPhone has led the wave of Micro SIM cards. The design of the built-in battery has been followed by other manufacturers.

The middle and low end are difficult to popularize. However, we can see that although the built-in battery has greatly changed the style of the whole machine design, it can have an integrated and beautiful body, but on the other hand, we have to be "practical". Considering that the original large-screen smart phone is very short of power, the built-in battery limits the endurance of the mobile phone, so from a practical point of view and cost, product positioning and other factors, in the future, the built-in battery may be in high-end mobile phones. It is reflected in the market, but it should not be widely used in the mid-end, especially the low-end mobile phone market.
