Show Detailed Battery Usage auf OnePlus
The default battery screen on your OnePlus usually shows usage since you last unplugged the charger. That view is short-term and often hides apps that ran quietly in the background hours earlier.
For a complete picture, Oxygen OS offers a full device usage view that covers the entire period since your last full charge. This includes system processes, screen-on time, and background activity for every installed app, not just the top few.
To open it, go to Open the Settings ➔ Tap on Battery ➔ Tap on View detailed usage ➔ Open the menu ➔ Tap on Show full device usage.
Once enabled, the list refreshes to show every app that consumed power, sorted by percentage or usage time. This is the view to check when you suspect a specific app is draining the battery faster than expected, or when the standard screen usage list looks incomplete.
If your phone was charged multiple times during the day, the full device usage view still reflects the most recent full charge cycle, not a rolling average.
