Time alone does not describe the intended finish. An ironing target, storage target and fixed timed programme can legitimately behave differently.
Understanding this situation
The initial moisture, fabric and load also matter. Comparing two durations without those details can make a normal programme choice look like a performance change or hide a real deterioration.
A useful next step
Record the complete settings and actual result from ordinary use. Keep within garment care limits. If a suitable familiar programme now consistently misses its target, report that pattern rather than diagnosing solely from the number of minutes displayed.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
