On September 17, 2025, foreign media sources reported that Apple has introduced a new feature in the watchOS 26 system for the Apple Watch: a warning for slow charging. When the Apple Watch senses that the charging process could be optimized, a notification reading "Charger speed is slow" will pop up in the "Battery" section of the Settings app. To visually differentiate between charging states, the system employs a color-coding scheme: slow charging is indicated by an orange hue, while fast charging is represented in green. Apple has officially stated that this alert is not a sign of a charger quality problem. Instead, it serves as a reminder to users that switching to a higher-wattage charger can lead to quicker charging times.
