How many people have complained about the non-removable mobile phone battery? Anyway, when I changed my mobile phone once, I was entangled for a long time because the battery of my favorite mobile phone was not removable. Because the aging of mobile phones often starts from the decline in battery life, if the battery is removable, I can buy a new battery immediately to make the mobile phone glow, only a few tens of dollars; and If the battery is not removable, the end of the battery means that the phone is almost dead.
What I didn't expect at the beginning is that almost all mobile phones have begun to use the design of non-removable batteries, and I have gradually discovered that non-removable batteries still have their reasons.
1. Avoid poor contact caused by loose battery or worn-out battery interface
The mobile phone can replace the battery, and we will frequently open the back cover. This will not only make the back cover and the battery loose, but the process of replacing the battery will also cause oxidation of the battery's metal contacts. Due to the poor contact between the battery and the body, it is easy to cause the phone to shut down and restart inexplicably.
2. Crack down on low-quality batteries that exist on the market
Remember the news about the explosion of mobile phones? After reading it, everyone will doubt the quality of the mobile phone itself or the practice of playing with the mobile phone while charging. Nothing wrong, but everyone has overlooked a decisive factor that makes danger: inferior batteries. Inferior batteries will not only greatly reduce the battery life during use, but also easily generate heat and malfunction.
What's more, inferior batteries not only threaten our personal safety, but also cause considerable damage to the mobile phone itself, affecting the lifespan and user experience of the mobile phone. From this perspective, although non-removable mobile phone batteries will not disappear the inferior batteries of various counterfeit brands, at least they will greatly reduce their circulation on the market.
3. Appearance consideration: save space, lighter and thinner
As early as a year ago, there was such an unwritten convention in the smartphone industry that the body thickness of more than 10mm would be regarded as a bad process design. And now this trend is getting more and more intense, it seems that nothing else matters, as long as this phone is thin enough, its design craftsmanship is good.
And designing the mobile phone battery to be non-removable can greatly save the space inside the fuselage, thus making the mobile phone thinner and thinner.
4. Practical considerations: more compact, can have a certain three defense capabilities
Although the ultra-high three-defense capability does not have much practical value, now mobile phone users have begun to pay attention to the three-defense capability of the mobile phone, especially the waterproof capability.
If a mobile phone uses a detachable battery, its back cover will definitely adopt the open design method, which makes it difficult to make the back cover and the body close to the ground. Non-removable batteries often have mobile phone back covers that can only be opened with the help of special tools, so the tightness and waterproof performance are naturally much better.
5. Market perspective: alleviate the saturation of the mobile phone market and suppress other battery brands
Why non-removable mobile phone batteries can alleviate the saturation of the mobile phone market? Because this can increase the circulation speed of mobile phones and speed up the replacement of each user's mobile phone. To put it bluntly, if the phone is not working, you can buy a new battery and you can continue to use it. This may make the phone manufacturers wait anxiously.
In addition, when buying a second mobile phone, users buy the original battery relatively few, and most of them buy other brands of electric boards. Since I can't make money on my mobile phones, I can't let other manufacturers who make mobile phones take advantage.
6. Increased battery power to meet daily needs
When I was in high school, the batteries of mobile phones were only a few hundred megabytes. Now, when you look at these mobile phones, the size of the battery is bigger as the screen is larger, and the power is always three or four thousand mAh or more. Although in general the battery life of mobile phones is still not ideal, this level of power can already allow us to complete our daily use.
7. Easy to make molds
One-piece molds are much more convenient to manufacture than segmented or detachable molds, which can save time and rent costs to a certain extent.
