Samsung One UI 9 Relocates Adaptive Battery Settings, Complicating Notification Fixes
The renaming of battery-saving features to 'Sleeping apps' makes it harder for Galaxy users to resolve background app delays.
Samsung has renamed and relocated its Adaptive Battery feature in One UI 9, moving the setting into a deeper menu labeled 'Sleeping apps.' This change alters how users manage background app restrictions, potentially complicating the process for those experiencing delayed notifications.
On devices running One UI 9, the functionality previously associated with Adaptive Battery is now found under Settings > Battery > Background usage limits > Put unused apps to sleep. Samsung has folded the feature into this 'Sleeping apps' section, leaving no setting explicitly named 'Adaptive Battery' for users to search for. This differs from Google's approach on Pixel devices, where the 'Adaptive Battery' label remains intact.
The Mechanics of App Throttling
Both Samsung's 'Sleeping apps' and Google's 'Adaptive Battery' rely on the underlying Android app bucket system. This system categorizes applications into tiers—Active, Working Set, Frequent, Rare, Restricted, and Never—to prioritize background jobs and synchronization. By throttling apps in lower-priority buckets, the system extends battery life by limiting how often those apps can wake the device or access data.
While high-priority notifications sent via Firebase Cloud Messaging (FCM) are designed to bypass these restrictions, the system can still cause issues. Google's own official documentation for Pixel phones acknowledges that Adaptive Battery may reduce overall performance and lead to delayed notifications for the user.
Impact on Power Users
This shift in terminology and location is particularly impactful for users of high-productivity hardware, such as the Galaxy Z Fold 8. These users typically run a higher volume of background applications to support intensive multitasking workflows. When battery-saving features throttle essential tools—such as Slack, smart home alerts, or delivery notifications—the inability to quickly locate and disable the restriction can result in missed critical communications.
Apps that are not perfectly implemented with FCM are the most susceptible to these delays. When such apps are placed into a 'sleep' state by One UI 9, they may be muted or delayed until the user manually opens the application.
What to Watch
As more users migrate to One UI 9, the lack of a standardized 'Adaptive Battery' label may lead to an increase in troubleshooting requests regarding notification reliability. It remains to be seen if Samsung will introduce a more discoverable search term or a simplified toggle to address these usability concerns. For now, users experiencing notification lag must navigate the 'Background usage limits' menu to manually exempt critical apps from being put to sleep.
