Auto-Brightness
Auto-brightness automatically adjusts your screen’s brightness based on the surrounding light conditions. It uses the phone’s built-in light sensors to detect the ambient light and adjusts the screen’s brightness accordingly. In darker environments, the screen brightness is reduced, while it is increased in brighter surroundings. This not only makes your screen more comfortable on the eyes but also helps conserve battery.
To enable auto-brightness, navigate to Settings > Accessibility > Display & Text Size, then scroll down to find and toggle on the auto-brightness option.
Additionally, activating the “Night Shift” feature can further extend battery life. This feature reduces the amount of blue light emitted by your screen and adjusts the color temperature to warmer tones based on the time of day. This can help reduce power consumption during the evening hours.
Auto-Lock
Auto-lock automatically locks your phone after a set period of inactivity. If your iPhone’s screen remains on for too long without use, it can rapidly drain your battery. To avoid this, Apple recommends adjusting the auto-lock to a shorter time.To adjust auto-lock, open Settings > Display & Brightness and scroll down to Auto-Lock. You can set it to as low as 30 seconds, ensuring your phone locks quickly when not in use.For users with the iPhone 14 Pro or later, Apple also suggests disabling the always-on display feature. This feature keeps the screen dimly lit and shows notifications, time, and other information even when the device is locked. Although it’s designed to have minimal battery impact, turning it off can still help improve overall battery performance. You can manage this setting from the Display & Brightness menu.
Location Services
Location services are useful for tracking your location for apps that need it, but it can also be a significant drain on battery life, especially when GPS is used. To conserve battery, it’s a good idea to disable location services for apps that don’t require it.
To manage location services, go to Settings > Privacy & Security > Location Services. You’ll see a list of apps with access to your location. You can either disable location services completely or turn it off for individual apps.
By making these simple adjustments, iPhone users can potentially double their battery life and avoid the frustrating “low battery” notifications.
