While Apple released an update to the operating system “iOS 15.4” in mid-March, users reported problems with iPhone batteries that led to their drain. A tweeter wrote on Twitter that there is a problem facing his phone battery, describing what is happening as “ridiculous.” “Why can’t you release the update in time, the battery dropped 5% in less than 10 minutes?” he said. Despite the harshness of the tweet, the technical support account in “Apple” responded professionally to the tweeter, thanking him for his comment, and said that the company would be happy to help him. He added that it is normal for the applications and features in the phone to need to make adjustments for a period of up to 48 hours, after completing the operating system update. And the technical support account in “Apple” asked the tweeter to communicate with the company, if the situation continues as it is, to solve the problem.
The technical news website techradar stated that to avoid the problem, the user needs to have the charger or portable power bank at hand for a while. Apple advises waiting a few days if battery life is drained (due to the update).
