评测博主极客湾通过专业测量发现，市面大多数零售手机存在电池"锁容"现象[1]。实际可用容量低于厂商标称值，容量释放率普遍在87%-95%之间[1]。以一款标称10000mAh的手机为例，实际可用电量仅为8500mAh出头[1]。相比之下，iPhone 17 Pro Max的容量释放率达到97.83%[1]，华为Mate 70 Pro+和Mate 80 Pro的释放率接近100%[1]，三星S26 Ultra超过98%[1]。
华为终端BG CTO李小龙对此现象作出解释[1]。他表示，这是因为高硅负极电池普及后，很多厂商的电源管理芯片未做低压适配，导致电池底部电量被浪费[1]。华为早在两年多前就预判到高硅电池会成为主流，提前完成了系统适配，将关机电压降至2.8V[1]。相比之下，苹果和三星尚未上马硅负极电池，主要是考虑国际物流成本的影响[1]。
Tech reviewer GeekBay has uncovered a widespread "battery capacity lock" phenomenon affecting most retail smartphones, wherein the actual usable battery capacity falls significantly below manufacturers' stated specifications [1]. Through professional measurements, the reviewer found that capacity release rates typically range between 87% and 95% across most tested models [1]. For instance, a smartphone marketed with a 10,000mAh battery can deliver only slightly over 8,500mAh of actual usable power [1].
However, flagship models from major manufacturers demonstrate notably better performance [1]. The iPhone 17 Pro Max achieves a capacity release rate of 97.83%, while both the Huawei Mate 70 Pro+ and Mate 80 Pro approach 100% [1]. Samsung's S26 Ultra similarly exceeds 98% [1]. According to Huawei Terminal Business Group CTO Li Xialong, the disparity stems from the adoption of high-silicon anode batteries across the industry [1]. Huawei anticipated this transition over two years ago and proactively adapted its power management systems, lowering the phone's shutdown voltage to 2.8V to optimize battery utilization [1]. Meanwhile, Apple and Samsung have not yet deployed silicon anode batteries, primarily due to concerns over international logistics costs [1].
