Before using battery-saving settings, unlock Developer Options:

1. Open Settings and go to About Phone (top or bottom of the list).
2. Find Build Number (or Version Number) and tap it 7 times. You’ll see “You are now a developer!”
   Pro tip: If Build Number isn’t visible, check under Software Information (varies by brand like Samsung or Xiaomi).

Once Developer Options are enabled, use these four settings:

1. Wi-Fi and Throttling

Go to Additional Settings > Developer Options. Enable “Wi-Fi and Throttling” to reduce unnecessary Wi-Fi activity, cutting battery drain while improving network performance. This often-overlooked setting makes a big difference.

2. Don’t Keep Activities

In Developer Options, turn on “Don’t Keep Activities”. This closes apps completely when you switch away, preventing background running. With 50+ apps on most phones, this stops hidden battery drain.

3. Clear Cache When Device Locked

Head to Battery Settings > Advanced. Set “Clear Cache When Device Locked” to 5 minutes. When locked, your phone auto-clears recent apps’ cache—reducing background activity and saving battery.

4. Battery Drain Notifications

In Battery Settings, enable “Battery Drain Notifications”. This alerts you when an app uses too much battery, so you can close or uninstall it quickly. The video emphasizes this helps identify problem apps fast.
