I don't have either of the two smartphones, but I think it is difficult to make an exact statement here, because all modern devices do not charge the battery linearly. In addition to the condition of your battery, the current charge level and time of day play a role. The charging curve is usually degressive, i.e. the battery is charged heavily at the beginning and then less and less in order to conserve the battery. Overnight, the battery is often only fully charged in the morning hours to be particularly gentle.
