Apple rolled out a small iPhone update on Thursday, iOS 15.4.1. The update follows the release of iOS 15.4 and resolves a battery-draining bug along with a security flaw that Apple says “may have been actively exploited” on some devices.

Some iPhone users took to Twitter to complain about battery drain after installing iOS 15.4. Apple Support responded to these customers by tweeting that it’s normal for some apps and features to adjust for “up to 48 hours after an update.”
