华为终端BG CTO李小龙就手机电池容量锁定问题作出解释，澄清这并非厂商有意限制用户使用，而是源于产品设计阶段的技术考量1。
李小龙指出，部分手机在设计时未能充分考虑低压工作环境下的电池表现1。他以水杯放水阀门作比喻解释其中原理：如果手机的关机电压设定高于电池的终止电压，电池中的容量就无法被完全释放1。相比之下，采用高硅电池的手机在低压条件下仍能释放出相当比例的容量，这与传统石墨电池存在明显差异1。因此，关机电压的设置高低成为影响电池可用容量的关键因素1。
Huawei Terminal BG Chief Technology Officer Li Xiaelong has clarified the controversy surrounding locked battery capacity in smartphones, explaining that some devices are not deliberately restricted by manufacturers but rather face inherent limitations stemming from their design approach 1. According to Li, the core issue lies in whether phones were engineered to operate under low-voltage conditions during their initial design phase 1.
Li elaborated on the technical mechanism behind this phenomenon using an analogy to illustrate how battery capacity release functions 1. He emphasized that the shutdown voltage threshold plays a critical role in determining how much battery capacity can actually be delivered to users 1. When a phone's shutdown voltage exceeds the battery's termination voltage, the remaining capacity becomes inaccessible and cannot be fully released to consumers 1. In contrast, high-silicon batteries demonstrate better performance than traditional graphite batteries when operating under reduced voltage conditions, allowing them to still discharge a considerable portion of their capacity 1. Li previously released an educational video addressing battery capacity issues in February 2024 1.
