1. The weight battery accounts for about 25% to 30% of the mobile phone body weight, accounting for a lot of space, and even has to design complex double-layer motherboard stacking design, optimize battery capacity, which has continued in the prior art The result of the compromise, the current mobile phone is new, iPhonexSmax has reached 208g, considering the use of mobile phones, larger volumetric batteries will newly add users' use burden. 2, the body volume does not affect other functions, the larger volume of battery will inevitably use the screen with a larger area, better display effect, and a larger display screen means greater power consumption.

, The new increase of battery capacity may only bring increase in mobile phone screen, and cannot extend the actual battery life. Considering the importance of mobile phone as a mobile device, too large screen does not meet the mobile phone usage scene. 3 Charge.

The charging time while the volume is larger, while charging time will increase significantly. In this case, many users are more likely to choose directly according to actual needs, and the large-capacity battery will lose meaning. 4, heat control control lithium-ion battery has high flammability, belonging to dangerous goods, mobile phone processor and other components will have a lot of heat, at this stage, the heat dissipation technology cannot support a large amount of heat in a short time, a large number of The heat gathering inside the body will not only affect the use, but also very dangerous, it is easy to explode.

In addition, there may be cost-controlled reasons, integrated, Apple may think that simple new battery capacity is not much significant, it is better than system optimization, it is more meaningful.
