Finally, I have found the admission from Apple where the conflict is between the career (in my case Vodafone with 5G service and international contract, these two elements are important) with Apple’s security service with their iOS; conflict with 5G service. The battery status is actually correct, sorry for correcting you; it qualifies what are the APP services being ‘interrupted’, the % or time is a reflection of a time stamp of when they are ‘open’ and ‘closed’ (I will not explain the programming terminology). Alas, it does not resolve the problem but explains the challenge with iOS because I do not have the same problem with my Android smartphone.
