The American electronics juggernaut Apple released a brand-new iPhone upgrade two days ago. All iPhones that are compatible with this latest update must already be running it.
Apple's update includes Big Fixus, emojis, and a special function that enables users to lock their phones with Face ID even when using face masks.
On the other hand, those who have loaded the iOS 15.4 update have reported a number of problems. Numerous complaints regarding the latest version have been made to GSM Arena, Phone Arena, Twitter, and Red T, which all provide fresh news about telephones.
Most people claim that since installing the latest update, their iPhone battery is depleting quickly. Many people claim that the iPhone 13 Promax is the model most impacted by this latest update in tweets made on Twitter.
The identical smartphone that ran for 12 hours before to the battery upgrade now only provides a challenging 7 to 8 hours of backup.
