iPhone

Goal: Reduce idle and background battery use, turn on Low Power Mode automatically.

Settings Guide:

• Open Settings

• Tap Display & Brightness, set Auto-Lock to 30 seconds or 1 minute

• Go to Settings, Battery, turn on Low Power Mode when you need extra savings

• In Settings, Background App Refresh, turn off for heavy apps you do not need running

Optional automation using Shortcuts, step by step:

• Open Shortcuts app

• Tap Automation at bottom

• Tap + then Create Personal Automation

• Choose “Time of Day” or “When Battery Level” (example: When Battery Level is 100% to 90% is not useful, pick Battery Level 20% to toggle off, instead choose Time of Day or Leave/Arrive)

• Tap Add Action, search for “Set Low Power Mode”, select it

• Set it to “Turn On”

• Turn off “Ask Before Running” if iOS allows it, confirm

• Save

Notes: Shortcuts can toggle Low Power Mode automatically. Auto-Lock cannot be changed by Shortcuts, so include Auto-Lock in the manual steps.

Estimated wattage reduction: About 1.5 W are reduced in idle when Low Power Mode and Auto-Lock are tightened
