The meaning of translation is: making the battery bigger is the key to prolonging the battery life. Larger batteries with more capacity will lead to longer usage times. When we design a mobile product, every point is very valuable. The connotation of making the battery bigger is to find a place to put a bigger battery. We found that if we used a detachable battery, a lot of space was wasted. A lot of space and volume are used in mechanical devices, structures, battery compartments, and even wrenches for battery removal. We removed these components related to the detachable battery through the embedded battery, so we built a laptop with 40% larger capacity and 8 hours of battery life without sacrificing size and weight. The detachable battery case, card slot and other designs take up space, thus reducing the capacity of the real battery (the detachable battery for the same body as the MX2, the battery capacity will be reduced by about 15%).

The benefits of a non-removable battery are the benefits of structural components

This eliminates the need to design a detachable back cover, which leaves the designer with more design space. Of course, mobile power manufacturers may say that they can finally promote mobile power products. At the same time, because once you run out of batteries, you can't continue to use the battery, so you have the concept of a "backup machine." It is convenient for a bunch of spare machine manufacturers to sell other mobile phones. The spare machine market is completely a market created by mobile phones that cannot replace batteries.

Any modern smartphone (including iPhone) can only last for half a day in moderate to heavy use (please put your own dog for various evaluations). If you need to use it all day, you can't change the battery. Power supply, it is better to replace the battery with two batteries.

What is the difference between mobile power and battery?

The difference is that once you have a mobile power supply, your equipment will not be elegant enough anyway, whether it is the size of the mobile power supply, the weight, or the size, or the line that the mobile power is connected to the mobile phone. s things. And if you carry two spare batteries? We know that the batteries are usually thin enough to carry. This makes you elegant. And this is the reason why I have an iPhone5 but also need to bring an android, because as long as I need to use more mobile phones on the day, the iPhone5 definitely does not last a whole day, but the mobile power supply is really too elegant, far better than no Bring one more device.
