iPhone 15
Question marked as
Changes in software such as upgrades may introduce new features which may add to power drain and heat generation. Check Settings > Battery feature to see if there are apps or services running that use a lot of power. If there are, decide if you need them running all the time, can turn off a service when an app is in the background, or disable the feature completely. Read this support article to learn about the battery health feature. —> iPhone Battery and Performance - Apple Support
