At first it seemed a problem exclusive to the iPhone 12 and Apple forums were filled with users annoyed with battery life after updating to iOS 14.2. Even Apple released an exclusive update.
However with the passage of time they have appeared users of other iPhone models reporting this same problem with battery after updating to this version of iOS.
The worst thing about this is that the cause of this high battery consumption could not be located. On other occasions this problem was caused by a specific application or service, but now nothing is known. This means that there are no special tricks to avoid this excessive energy consumption, beyond the usual classic tricks.
