When ICON is turned off, a flashing LED shows the remaining battery. Green indicates 75% and red indicates less than 25%.
The smartphone companion application also gives an indication of the battery level. However, battery level and usage is extremely hard to predict accurately in a light which reacts to its environment. Due to the algorithms used, the battery may vary by around 10% to the indicated value.
More accurate forecasting using advanced AI processing is under development - when ready, this will enable runtimes to be shown, rather than battery levels. This will be available via a simple and free smart phone application and device firmware update.
The battery level is intended as a guide only. There is no disadvantage to regular charging and we recommend that ICON lights are charged when they reach 50% battery capacity or around 7 hours of runtime in flash mode (whichever comes sooner).
