iPhone users have the option to adjust their device’s screen brightness as high or low as they prefer. Some people choose a high level of brightness, which is not advisable as it will make your eyes tired and dry, not to mention that it will use up the battery life of your iPhone very quickly. Many users would try to find the balance, aiming to make their screen not so bright that it will hurt their vision but not as opaque that they would have difficulty reading content on their iPhone. There is an Auto-Brightness setting that can control the brightness according to how dark or illuminated are your surroundings. However, if you are looking for a way to save battery life, you may need to set a lower level of brightness. Follow the below steps to adjust the screen brightness of your iPhone as a way to extend the battery life of your device.
1. Go to the Settings menu, tap Brightness & Wallpaper.
2. Switch Auto-Brightness off to ensure that you can adjust the brightness manually and that your iPhone will not do it automatically, based in the light available where you are
3. You can change the brightness settings manually moving the slider to adjust it to the level of light you are comfortable with. Make sure that you do not select the highest level of brightness but also, do not go so low that you can’t even see the content in your screen.
When you are in a place where the light is minimum, you can adjust the brightness manually and lower it up a little. If the light around you is too intense, you will need your screen to be brighter. This simple adjustment will allow you to prolong the battery life of your iPhone so you will not have to worry to much if you are on the go and don’t have a way of charging the battery.
