  • App efficiency improvements

11. Optimize Email Settings

Constantly checking for new email drains battery.

Change from Push to Fetch:

  1. Go to Settings > Mail > Accounts > Fetch New Data
  2. Disable Push
  3. Set Fetch to Every 15 Minutes or Hourly

Or manual refresh:

  • Set to Manual to check email only when you open the app

This can save 10-20% battery per day.

12. Disable Unnecessary Visual Effects

Turn off features you don't need.

Dynamic wallpapers:

  1. Go to Settings > Wallpaper
  2. Choose a static image instead of dynamic or live wallpapers

Siri suggestions:

  1. Go to Settings > Siri & Search
  2. Disable Suggestions in Search, Look Up, and Lock Screen

Widgets:
