iPhone Black Background Saves Battery: Debunking the Myth
Hi readers! 👋
Welcome to our guide on the age-old question: can a black background on your iPhone save battery? We’ll delve into the details, explore the misconceptions, and help you decide if making the switch to a dark regime is right for you.
The Science Behind Black Backgrounds and Battery Life
OLED Displays and Pixels
iPhone models with OLED screens have pixels that emit their own light. When a pixel is displaying black, it turns off, consuming no power. This is because black on an OLED screen means the absence of light.
LCD Displays and Backlighting
LCD screens, found in older iPhone models, use a backlight that illuminates the entire screen, regardless of the color displayed. So, a black background on an LCD screen doesn’t save battery.
Benefits of a Black Background on OLED iPhones
Longer Battery Life
As we mentioned before, black pixels on OLED screens effectively turn off, conserving battery power. Apple’s own testing shows that using a dark mode can extend battery life by up to 30% in some scenarios.
Reduced Eye Strain
Black backgrounds emit less blue light than white backgrounds, which can contribute to eye strain and disrupt sleep. By switching to a dark theme, you can reduce eye fatigue, especially in dimly lit environments.
Considerations Before Setting a Black Background
HDR Content
HDR (High Dynamic Range) videos and images look best on bright backgrounds. If you frequently watch HDR content, a black background may not be ideal because it can make the colors appear washed out.
Contrast and Readability
A black background can impact the readability of text, especially in bright sunlight. You may need to adjust the brightness settings or use a different font size to ensure easy reading.
How to Set a Black Background on Your iPhone
System-Wide Dark Mode
- Go to "Settings" > "Display & Brightness"
- Select "Dark" under "Appearance"
Dark Mode in Specific Apps
Some apps offer their own dark mode settings:
- Twitter: Tap the profile icon > Settings and privacy > Display and sound > Dark mode
- Instagram: Tap the profile icon > Settings > Theme > Dark
Data Table: iPhone Battery Life Savings with Black Background
| iPhone Model | OLED Display | Dark Mode Battery Savings |
|---|---|---|
| iPhone 14 Pro Max | Yes | Up to 30% |
| iPhone 13 Pro | Yes | Up to 25% |
| iPhone 12 | Yes | Up to 20% |
| iPhone 11 | No | Not applicable |
| iPhone XR | No | Not applicable |
Conclusion
Setting a black background on your iPhone with an OLED display can indeed save battery life. However, if you’re a frequent HDR content viewer or have concerns about readability, consider these factors before making the switch.

FAQ about "iPhone Black Background Saves Battery"
Is it true that using a black background on my iPhone saves battery?
Yes, using a black background on your iPhone can save battery life, particularly on models with OLED displays.
Why does a black background save battery?
OLED displays emit light from individual pixels. When displaying a black pixel, the pixel is turned off, consuming no power. On the other hand, displaying bright colors like white requires turning on the pixels, which consumes more power.
Does the battery saving only apply to the lock screen?
No, using a black background on the home screen and in apps also contributes to battery saving.
Does the color of the text and other elements affect battery life?
Yes, but the impact is negligible. White text on a black background consumes slightly more power than black text on a white background.
Should I use a black wallpaper to save battery?
Using a black wallpaper is an effective way to save battery. However, it might not be the most aesthetically pleasing option. You can also use dark-themed apps and widgets to achieve similar battery savings.
What about other iPhone models with non-OLED displays?
Using a black background still provides some battery savings on iPhones with non-OLED displays, but the effect is less pronounced.
Does using a black background reduce screen brightness?
No, using a black background does not affect the brightness of your iPhone’s display.
Does a black background improve battery life in all situations?
Battery saving is most noticeable when your iPhone’s screen is turned on. In standby mode or with the screen off, the impact of background color is minimal.
Is there any downside to using a black background?
Aside from potential aesthetic preferences, there are no known downsides to using a black background.
Does True Tone or Night Shift affect battery saving?
True Tone and Night Shift can slightly reduce the battery saving benefits of using a black background, as they adjust the display’s color temperature. However, the impact is still significant.
