Since Apple Watch is also meant to minimize smartphone screen time engagement, it will also minimize iPhone’s battery consumption. However, unusual loss of power from your iPhone battery may send a mixed signal either your battery is worn out or due to a charging error.

Hence, many iPhone users have tried to optimize some apps to save power without finding the cause.

Well, background running apps could be the possible cause, but have you checked if pairing your iPhone with other devices could be the potential cause.

For instance, many iPhone users have recently reported that Apple Watch is draining their iPhone Battery. In fact, following the release of iOS 14.6, Apple Watch drains about 25% or more of iPhone battery power within 8 hours.

This issue is not new to Apple’s team, because they introduced native apps for Apple Watch to minimize the consumption burden from the iPhone’s battery.
