Display Settings and Their Impact

The display is a major power consumer in smartphones. Both the S21 Plus and S20 Plus have vibrant AMOLED displays, but how they're configured significantly affects battery life. The screen's brightness level is a primary factor. The brighter the display, the more power it consumes. Setting the brightness to auto-brightness and enabling adaptive brightness features can help save battery. The refresh rate of the display also influences power consumption. The S21 Plus offers an adaptive refresh rate, which can dynamically adjust between 48Hz and 120Hz based on content. This feature helps to save battery compared to the S20 Plus, which has a fixed refresh rate of either 60Hz or 120Hz. Lowering the refresh rate when possible can extend battery life. The resolution of the display also affects battery life, although the difference might not be immediately noticeable. Running the display at a lower resolution can save some battery power. The Always-On Display (AOD) feature, which keeps some information visible on the screen even when the phone is locked, also uses power. Disabling the AOD or setting it to only activate when tapped can increase battery life. Dark mode is another great feature to extend battery life. The AMOLED displays in both phones can save power when displaying dark colors, as the pixels are essentially turned off in dark areas of the screen. Using dark mode across the system and in compatible apps can have a positive impact on battery life. The display settings are essential for maximizing battery life on either phone. Adjusting the brightness, refresh rate, resolution, and AOD settings can make a real difference in how long your phone lasts on a single charge. The S21 Plus, with its adaptive refresh rate and optimized software, might provide better control over display-related battery consumption than the S20 Plus.
