USB-IF has updated the USB Type-C Cable Specification to more clearly define current stability under sustained load conditions, refining how cable performance is evaluated in Power Delivery applications and improving consistency across certification and interoperability testing.

UL 62368-1:2025 introduces stricter safety expectations for chargers and power banks, pushing buyers to focus on thermal stability, protection design, and model-level certification rather than relying on legacy compliance.

Mini power banks deliver strong charging performance because their boost converters turn a 3.7V internal cell into stable 5V–12V output. Efficiency, heat control, and protocol chips determine real-world quality.

Recent lab reports show a growing rise in smartphone damage caused by counterfeit USB-C cables, which fail basic safety tests, overheat under fast charging, and quietly shorten battery lifespan.

A new EU consumer report shows that 40% of power banks do not meet their claimed capacity, with many delivering only 55%–80% of the advertised mAh. Regulators warn this signals poor-quality cells and potential safety risks.

Realme has unveiled an AI-powered Smart Charging System that can extend smartphone battery health by up to 25%. The algorithm adjusts voltage and current in real time, reducing heat and chemical stress during PD and PPS fast charging. Tested on the Realme GT7 Pro, it improves battery cycle life from around 800 to 1,000 full charges. This launch marks Realme’s move toward sustainable fast charging and aligns with the global push for longer-lasting smartphone batteries.

Xiaomi has officially started mass production of its BN58 smartphone battery series, designed for flagship Mi and Redmi models. Using a stacked-layer lithium polymer design with silicon-carbon anode materials, the BN58 achieves 5300mAh capacity, 12% better energy retention, and 18% higher thermal stability than the BN54. Optimized for 120W PD fast charging, it represents Xiaomi’s push toward safer, denser, and more efficient smartphone battery production.

Apple will introduce detailed battery health transparency in iOS 19 for iPhone and iPad, showing cycle counts, capacity projections, and replacement guidance.

Samsung issued a safety notice after swelling reports in older Galaxy batteries. Users are advised to check devices and seek authorized replacements.

UL warns nearly 88% of aftermarket smartphone batteries fail safety tests, citing overheating, swelling, and counterfeit labeling risks.

The Samsung Galaxy S25 Ultra packs a 5000mAh battery with USB-C PD and 45W Super Fast Charging 2.0. It typically charges to about 65% in 30 minutes while keeping heat under control. Myths about fast charging are debunked: certified cables and GaN chargers ensure safe performance. By staying in the 20–80% range, avoiding heat, and updating software, users can extend battery health and enjoy reliable daily power.

Anker recalled over 1.1M PowerCore 10000 (A1263) units on June 12, 2025 after reports of overheating and fires. Within weeks, two U.S. federal class-actions in California and New York alleged poor recall notice and misleading safety claims. Anker says the recall was voluntary with refunds available, but lawyers demand damages and broader coverage. Consumers are urged to stop using affected units and contact Anker or report to CPSC.

The Wireless Power Consortium (WPC) has launched the Qi2 wireless charging standard, boosting maximum output from 15W to 25W. With a Magnetic Power Profile for automatic alignment and enhanced safety compliance, Qi2 ensures faster, more efficient charging across iPhone and Android devices. Certified Qi2 accessories, including chargers and power banks, are expected on the market by late 2025.

Samsung and Xiaomi have announced progress on graphene-based smartphone batteries, promising up to 60% faster charging and longer lifespan. This breakthrough could reshape mobile use, making devices charge in minutes and transforming power banks and fast-charging cables. Consumers are advised to prepare by choosing certified USB-C PD accessories and reliable power banks to stay ready for the next generation.
