Mobile phone battery: which is better All-in-One model or battery changeable model?

In various mobile news articles, for example, the theme is "HTCOne2 camera is keep the same", " Samsung GALAXYS5 will use 2K screens, etc., normally people always bring comments to battery, like "battery cannot be replaced is not considerable" or " hate to going out with an attachment". It seems everyone pays attention to the battery, and even over CPU, camera and other more important configurations.

For the rapid development of other mobile phone configurations, the battery brother can really drag everyone's hind legs. Whether you can change the battery will make everyone so entangled, in fact, it is only the surface of the problem, and the root cause is not that the development of battery technology cannot keep up. Let's talk about what happened to the current mobile phone battery? The article does not want to make the topic too ambitious, but also wants to collect what people think about now.

The design of the integrated body, or the design of the replaceable battery, is nothing more than a transition of the manufacturer in the current development of the mobile phone. The replaceable battery design the tradition of the previous functional machine period, and the integrated body can imagined to later. Direction of development. The only problem now is that the mobile phone battery technology can't keep up with the pace, which leads everyone to be so entangled in the battery problem. If the battery can support for a long enough time, I believe most people will not resist the design of the integrated body. After all, it seems that the iPhone, HTC, Sony and other integrated body designs all show a high level of industrial design.

IPhone's excellent integrated body design

I have seen many netizens commenting that they like mobile phones with replaceable batteries, and bring one or two spare batteries when they go out. Although the spare battery not necessarily used in many cases, but at least the body is still relatively solid. Xiao Bian can understand this situation; "low battery panic" will make everyone restless. Another way of course is to use mobile power, although many people do not want to drag the tail of the phone, but it can only be a compromise.

The solution to the problem of palliative

No matter which design, what mobile phone manufacturers can do now is to increase the capacity of the battery. It can say that it is a simple, rude, and helpless solution. Now the basic flagship model has a battery capacity of around 3000mAh, and there not many that can reach 4000mAh. Although the battery capacity has increased year by year, do not forget that other hardware like CPU, screen, etc. is developing rapidly, especially the power-hungry screen. Nowadays, the screen of such a large size increases the battery capacity compared with the battery capacity. Even less durable than before.

At present, the weight capacity ratio of lithium-ion polymer battery materials is about 150 mA/g. Without good industrial design, the pursuit of high power can only lead to the appearance of a tragic mobile phone. Although there are many mobile phones that have long standby functions, they do not change the battery technology. They only use the most advanced power-saving settings on the system, but neither power saving nor performance can achieved. So you have not found any high-end. The flagship uses long standby as a selling point.

Another way to cure the symptoms is the mobile power just mentioned. A mobile power supply with a capacity of several thousand milliampere hours or tens of thousands of milliampere hours can alleviate the "low battery panic disorder". However, under the same technology as the mobile phone battery, the higher capacity of the mobile power supply has a corresponding increase in volume and weight, and the portability has certainly declined. Moreover, many children's shoes are also very resistant to mobile power.

What should I do in the future?

Lithium batteries, which are standard on mobile phones and other electronic devices, are now widely used in our lives due to their high voltage, low consumption, low internal resistance, and many cycles. A lithium metal battery is a type of battery using a lithium metal or a lithium alloy as a negative electrode material and using a nonaqueous electrolyte solution. At this stage, lithium batteries can only be the most ideal battery products for mobile phones. At present, a lithium battery can replace a new type of battery material that can replaced by a small battery and a large capacity, even if it is price-friendly and capable of mass production. Row.

At the recent CES2014, the British Intelligent Energy company showed the latest up hydrogen fuel cell. The battery does not need to recharged, but the fuel cartridge replaced. Each fuel cartridge can charge the smartphone for 5 times. However, this fuel cell is more like a mobile power source than a built-in battery, so there is still a long way to go to replace the lithium battery.

At present, various high-tech batteries including fuel cells, water-fuel cells, organic radical batteries, etc. still under studied, but if we still use lithium batteries, they are still not qualified as universal battery products. Lithium battery has been in service for so many years, and it has indeed done its best. Now manufacturers are focusing on development of other mobile phone hardware, but one day they will reach the bottleneck or even saturation, but development of mobile phone battery is not directly proportional, mobile phone batteries will bring a big change one day, and manufacturers will pay most attention to the standby problem. At that time, you can enjoy all the convenience of mobile phone without worrying about standby problem. We look forward to that day.
