北京共享充电宝改按分钟计费，怎么反而贵了？

Core Viewpoint - The charging rules for shared power banks in Beijing have shifted from a fixed time billing system (every 30 or 60 minutes) to a per-minute billing system, leading to increased costs for consumers despite the intention of more precise billing [1][2][4]. Pricing Changes - The new per-minute billing rates have resulted in higher costs for consumers. For example, a user who rented a power bank for 120 minutes paid 6 yuan under the new system, compared to 5 yuan for 148 minutes under the previous system [2][4]. - The average cost per minute has increased, with many locations charging between 0.08 yuan and 0.12 yuan per minute. This has led to significant price hikes, such as a 50% increase in hourly rates at some locations [4][5]. Consumer Experience - Consumers have reported confusion and dissatisfaction with the new pricing structure, as the cost can exceed previous rates if usage slightly surpasses the new billing thresholds [6][7]. - The inconsistency in pricing across different locations, even within the same brand, has created a chaotic environment for consumers, making it difficult to compare prices effectively [7][8]. Industry Response - The shift to per-minute billing is aimed at meeting diverse consumer needs, but it has also led to hidden price increases at many points [5][7]. - Some brands have maintained their previous pricing structures, indicating that not all companies are following the trend of increasing prices under the new billing system [6].
