Apple’s support team has responded to complaints about the latest iOS 15 update causing faster battery drain on iPhones and has come up with a solution. It’s common for iOS updates to cause the iPhone battery to drain faster than usual, such as this has happened since iOS 14.6. Likewise, users complained about the same issue when the iPhone 12 Pro came out.
However, with the issue affecting a large number of iOS 15.4 users, Apple has provided an explanation and suggestion. Apple has not acknowledged any unusual battery drain issues detected. Instead, it just provides suggestions after applying an iOS system update.
Thanks for reaching out. Our team will review your message as soon as possible.
