1. Check what is using power
Search Settings for battery and review the usage breakdown. An app you have used for hours should appear in the list; a high position alone does not mean it is faulty. Look for activity that does not match how you used the phone.
Review unnecessary background activity for apps you rarely need. Be selective: restricting a messaging, navigation or backup app can affect notifications or work you expect it to do while it is not on screen.
2. Reduce avoidable screen use
Use a brightness level that is comfortable for your surroundings and a screen timeout that suits you. A screen left bright and active while you are not looking at it still uses power.
If your phone offers a refresh-rate choice, try a lower setting and compare the experience. The change may make scrolling feel different. Keep the setting that gives you an acceptable balance for your routine.
3. Use Battery saver thoughtfully
Battery saver can reduce background activity and other power use when you need to stretch the remaining charge. Check its description on your device so you know which functions it changes.
After enabling it, confirm that the messages and apps you depend on still behave as expected. If they do not, review the relevant app settings rather than disabling every background service.
When settings do not explain the problem
Compare similar days before judging a change: signal strength, screen time and app use can vary substantially. If unexplained drain continues, consult Xiaomi's troubleshooting guidance or official support for your exact model.
This guide does not promise a specific number of extra hours. The useful result is identifying avoidable power use while keeping the features you need.
