Why do mobile phones now use non-removable batteries?

Why use such a design as a non-removable battery? NO.1 Thinner and better performance The battery in the past can be removed, so there will always be some space in the middle, but after it becomes non-removable, the mobile phone battery and the back cover of the mobile phone will fit closely. Of course, there is no need to leave space without disassembly. This naturally reduces the thickness, and the parts inside are also available. In addition to this, after becoming non-removable, the performance of waterproof, dustproof and shockproof has also been improved. Kill two birds with one stone. NO.2 is safer. Remember that in the past our mobile phones could replace the battery board, right? Take two batteries when you go out, and change one when you run out of power. Since then, you have not only a universal charger, but if you buy these things, will you buy the original ones or the cheap ones? Most people may not adopt the original method, which leads to potential safety hazards. If you use non-original accessories, the probability of potential safety hazards is greatly increased. The original battery is easy to burn and explode. You still use a non-original one. , If the problem occurs, it may be blamed on the mobile phone. The mobile phone manufacturer has become a man of the back. Who else will buy this mobile phone if the word of mouth is bad? Without batteries and universal chargers, we now use more power banks. As long as the capacity of the power bank is large enough, it can generally charge the mobile phone several times, and it can also charge several mobile phones at the same time, which is almost a mobile power bank. The existence of ah, although the bulk is not easy to carry, but there is no way to do it. If the old mobile phones require batteries and universal chargers, then today's smart phones only use power banks. NO.3 is easy to recycle, environmental protection is now more and more advocate the theme of environmental protection, if it is a removable battery, the battery is broken, we may throw the battery in other trash and throw it away, but in fact, the battery will cause extreme damage to the environment. Large pollution, there are many heavy metals in it. If it is not removable, it will be recycled together with the mobile phone, which is more environmentally friendly and easier to recycle.
