Fast phone power saving for emergency situations.
Turn on Low Power Mode
Activates a special mode that reduces battery use across the whole phone.
Open Settings > Tap Battery > Tap the switch next to Low Power Mode so it turns green
Low Power Mode reduces background activity, pauses email fetching, lowers screen brightness, disables visual effects, and limits processor speed, which can extend battery life by up to 30%.
Turn on Airplane Mode in weak signal areas
Stops the phone from constantly searching for a network signal.
Swipe down from the top-right corner of the screen to open Control Center > Tap the orange airplane icon so it turns orange
When signal is weak, the phone uses maximum power to find and maintain a connection to cell towers. Airplane mode stops all radio activity, which is the biggest drain on the battery.
Lower screen brightness
Makes the screen darker, which uses much less power.
Swipe down from the top-right corner of the screen to open Control Center > Find the brightness bar (sun icon) > Drag it down with your finger until the screen is dim but still readable
The screen is one of the largest battery consumers on the phone. Reducing brightness by 50% can significantly cut power use.
Turn off Wi-Fi when not in use
Stops your phone from constantly searching for Wi-Fi networks.
Open Settings > Tap Wi-Fi > Tap the switch at the top so it turns gray (off)
Even when not connected, Wi-Fi continuously scans for available networks, which drains battery. Turning it off completely stops this activity.
Turn off Bluetooth
Stops the phone from looking for wireless devices like headphones.
Open Settings > Tap Bluetooth > Tap the switch at the top so it turns gray (off)
Bluetooth continuously scans for nearby devices to pair with, which consumes power even when no device is connected.
Shorten screen timeout (Auto-Lock)
Makes the screen turn off faster when you stop using the phone.
Open Settings > Tap Display & Brightness > Tap Auto-Lock > Tap 30 Seconds
The screen uses significant power when on. Locking it sooner reduces unnecessary screen-on time when the phone is set down.
Turn off Always On Display (iPhone 14 Pro and newer)
Stops the screen from showing time and notifications when locked.
Open Settings > Tap Display & Brightness > Tap Always On Display > Tap the switch at the top so it turns gray (off)
Always On Display keeps part of the screen lit even when the phone is locked, continuously using battery. Disabling it can save 5-10% per day.
Turn off Background App Refresh
Stops apps from updating themselves when you are not using them.
Open Settings > Tap General > Tap Background App Refresh > Tap Background App Refresh again at the top > Tap Off
Apps refresh content in the background to stay updated, which uses data and processor power. Disabling this stops all background activity and can dramatically extend battery life.
Turn off Location Services
Stops apps from using GPS to track where you are.
Open Settings > Tap Privacy & Security > Tap Location Services > Tap the switch at the top so it turns gray (off) > Tap Turn Off to confirm
GPS is one of the most power-hungry features. Many apps request location even when not in use, constantly draining the battery.
Switch from 5G to LTE (4G)
Uses an older, more efficient mobile network.
Open Settings > Tap Cellular (or Mobile Data) > Tap Cellular Data Options > Tap Voice & Data > Tap LTE
5G networks consume more battery than 4G/LTE due to higher data speeds and more complex antenna usage. LTE provides adequate speed while using less power.
Turn off Raise to Wake
Stops the screen from turning on every time you pick up the phone.
Open Settings > Tap Display & Brightness > Find Raise to Wake > Tap the switch so it turns gray (off)
Raise to Wake activates the screen with every movement, causing unnecessary screen-on time and battery use throughout the day.
Turn off Vibration
Stops the phone from buzzing for calls and notifications.
Open Settings > Tap Sounds & Haptics > Tap the switch next to Vibrate on Ring so it turns gray > Tap the switch next to Vibrate on Silent so it turns gray
The vibration motor uses significantly more power than playing a ringtone. Disabling vibration saves battery on every notification.
Set Mail to Manual Fetch
Stops email from constantly checking for new messages.
Open Settings > Tap Mail > Tap Accounts > Tap Fetch New Data > Tap the switch next to Push so it turns gray > Scroll down and tap Manually
Push email keeps a constant connection to the mail server, draining battery. Switching to Manual means email only updates when you open the app.
Turn off Hey Siri
Stops the phone from constantly listening for voice commands.
Open Settings > Tap Siri & Search > Tap the switch next to Listen for Hey Siri so it turns gray (off)
Hey Siri requires the microphone to be always active listening for the wake phrase, which continuously uses small amounts of power.
