Xi Niu Cai Jing·2025-07-10 11:15Core Viewpoint - Google is taking emergency measures to address battery overheating issues in Pixel 6a devices, pushing a mandatory system update globally to mitigate safety risks associated with battery performance [1][5]. Group 1: Incident Overview - At least 12 user reports of overheating, splattering, melting, and even fire incidents have been documented, primarily affecting devices with over 400 charging cycles [1][5]. - The main cause identified is the degradation of battery chemical materials leading to abnormal increases in internal resistance [1]. Group 2: System Update Details - Users are advised to update their systems immediately and to use original chargers, while high-cycle devices should avoid simultaneous charging and usage [3]. - The system update will implement several changes, including: - Charging speed limitation, reducing peak power from 18W to 12W [3]. - A 15% reduction in full battery capacity, resulting in a real-world decrease in battery life of approximately 1.5 hours [4]. - A temperature threshold that triggers performance throttling at 40°C, leading to a potential 30% decrease in gaming frame rates [4]. Group 3: Compensation and Support - The update will only affect specific batches, with new devices and those not reaching the charging cycle threshold remaining unaffected [5]. - Starting July 21, users in the US, Canada, the UK, and five other countries can receive free battery replacement services (valued at $89) or choose between $100 cash compensation or a $150 Google Store voucher [5]. - Users in non-first-round support regions, such as Brazil and India, will need to seek paid repairs through third-party service points [5]. Group 4: Historical Context and Future Implications - Previous incidents include a battery swelling issue with Pixel 4a in January 2025 and a compensation plan costing $23 million for Pixel 7a in April [5]. - Analysts suggest that Google needs to restructure its battery supply chain rather than relying on software patches to address these issues [5].
