Does Dark Mode Save Battery Life on Android or iPhone?

Does Dark Mode Save Battery extend our device usage? Dark Mode isn’t going to significantly extend your battery life, but it is at least a bit easier on the eyes and cool-looking. Dark Mode impacts battery as we stack it up against factors like Screen Brightness and usage of App/Device settings after all. More and more developers adopt dark mode into their apps, and different users speculate that enabling dark mode can save battery life on smartphones. Ultimately, your decision to use dark mode is a matter of personal preference. Test both light and dark modes separately and see which works better for you on your device.

Does Dark Mode Save Battery Life?

Dark mode doesn’t save power or enough of it to be awarded credit for saving our batteries. The Art And Science Of Saving OLED screens can switch off individual pixels when they are displaying black, the theory being this should mean less power drain. It’s worth noting that the actual battery savings are generally much less than the maximum advertised.

According to research conducted at Purdue University, changing to dark mode from light mode can save only 3-9% of battery saving for most users switched to dark mode. On the other hand, this is a not insignificant number. The contrast of dark mode with background white words may have a small impact on battery consumption when screen brightness is set to mid- or high levels.

Various factors such as screen brightness, the content you’re currently viewing, and other power-hungry applications will affect your final number. In addition to longer battery life, dark mode has various pluses. In low light, it can reduce eye fatigue, make things look nicer, and be easier to access. While dark mode may not be the solution to every device’s life, it does add value to a better overall smartphone experience.

Impact of Dark Mode on OLED vs LCD Screens

Dark mode does make a difference to battery life with devices that have an OLED screen—like many high-end smartphones—and therefore more than likely improve your battery power. Well, the interface is darker, meaning less power consumption from the display.

Dark mode has been hailed as a potential battery saver, especially for OLED screens.OLED displays include the technology that turns off individual pixels when the display is black which, it is argued, makes things even better in terms of power consumption. Still, the actual battery-saving effects of dark mode may not be as significant as many imagine. Studies have shown that dark mode can extend battery life, but the amount of time and money saved depends on your device and patterns of usage.

Here’s a comparison of OLED vs LCD screens using bullet points:

OLED (Organic Light-Emitting Diode):

• Better contrast:
• Can display true blacks by turning off individual pixels
• Higher contrast ratio for more vibrant images
• Energy efficiency:
• Uses less power, especially when displaying dark content
• Can improve battery life on mobile devices
• Thinner and lighter:
• No need for a backlight, allowing for slimmer designs
• Faster response times:
• Pixels change color more quickly, reducing motion blur
• Better viewing angles:
• Colors and contrast remain consistent from various angles
• Flexible displays:
• Can be used to create curved or foldable screens

LCD (Liquid Crystal Display):

• More affordable:
• Generally cheaper to produce, especially for larger screens
• Longer lifespan:
• Less prone to burn-in or image retention
• Brighter displays:
• Can achieve higher brightness levels, better for outdoor use
• More consistent colors:
• Less variation between individual units
• Better for static images:
• No risk of burn-in for applications like digital signage
• Lower power consumption for bright content:
• More efficient when displaying mostly white or bright images

Which is better?

• For mobile devices:
• OLED is generally preferred for high-end smartphones and tablets
• For TVs:
• OLED is favored for premium models, LCD for budget-friendly options
• For monitors:
• LCD is still common, but OLED is gaining popularity in high-end models
• The “better” choice depends on specific use cases and personal preferences

Does Dark Mode Save Battery on iPhone?

For iPhone users, dark mode was introduced in iOS 13. It functions similarly to Android’s dark mode, offering the same potential battery-saving benefits for OLED-equipped models, such as the iPhone X, XS, 11 Pro, 12, 13, and 14 series. The effectiveness of dark mode in saving battery life on iPhones depends on the specific model. iPhones with OLED displays, such as the iPhone X and later models, can benefit from dark mode in terms of battery savings. When using dark mode on these devices, the OLED screen can turn off pixels displaying black, resulting in reduced power consumption. This can lead to noticeable battery savings, especially when using apps with predominantly dark interfaces.

However, for iPhones with LCD screens, such as the iPhone XR or older models, the impact of dark mode on battery life is minimal. While dark mode may not significantly extend battery life on these devices, it can still provide other benefits such as improved readability in low-light conditions and reduced eye strain. It’s worth noting that the actual battery savings from dark mode on iPhones can vary depending on factors such as screen brightness, app usage, and overall device settings.

Does Dark Mode Save Battery on Android?

The impact of dark mode on battery life for Android devices is similar to that of iPhones, depending on the type of display used. Android phones with OLED screens can benefit from dark mode in terms of battery savings. Many high-end Android devices, such as those from Samsung, Google, and OnePlus, use OLED displays and can take advantage of the power-saving features of dark mode. When using dark mode on these devices, the OLED screen can turn off pixels displaying black, resulting in reduced power consumption.

For Android phones with LCD screens, the battery savings from dark mode are minimal. However, Android devices often come with additional power-saving features, such as battery-saver mode, which can help extend battery life. These modes often work in conjunction with dark mode to reduce overall power consumption. It’s important to note that the effectiveness of dark mode in saving battery life on Android devices can vary depending on factors such as screen brightness, app usage, and the specific implementation of dark mode by the device manufacturer.

Dark Mode vs Light Mode – Which Is Better For User Experience?

The choice between dark mode and light mode ultimately comes down to personal preference and specific use cases. Dark mode can provide a more comfortable viewing experience in low-light environments, reducing eye strain and potentially improving sleep quality when using devices before bedtime. It can also enhance the visibility of content on OLED screens, making colors appear more vibrant against a dark background. However, light mode may be more suitable for well-lit environments and can improve readability for some users.

From a battery-saving perspective, dark mode may offer some advantages, particularly for devices with OLED screens. However, the overall impact on battery life is often less significant than many users expect. It’s important to consider other factors that affect battery consumption, such as screen brightness, app usage, and network connectivity. Ultimately, the choice between dark mode and light mode should be based on personal comfort and visual preferences rather than solely on potential battery savings.

Does screen brightness save battery?

Screen brightness plays a crucial role in battery consumption, often having a more significant impact than the choice between dark mode and light mode. Many devices offer battery-saver modes that automatically reduce screen brightness to conserve power. These modes often work in conjunction with other power-saving features, including dark mode, to extend battery life. When using battery-saver mode, the screen brightness is typically lowered, which can result in substantial power savings, especially on devices with OLED displays.

For iPhone:

For Android:

It’s worth noting that while reduced brightness can help save battery life, it may also affect visibility and user experience. Finding the right balance between battery savings and usability is key. Many devices offer auto-brightness features that adjust the screen brightness based on ambient light conditions, helping to optimize both visibility and power consumption. When combined with dark mode and other power-saving techniques, managing screen brightness can significantly contribute to extended battery life on both Android and iPhone devices.
