Full brightness can harm your battery, eyes, and phone—change this habit today
Display Brightness Effect: If you have a habit of using your phone at full brightness, it can harm your eyes, the phone itself, and the battery. Therefore, you should avoid using your phone at maximum brightness.
Display Brightness Effect: Nowadays, it is difficult to go even a few hours without a smartphone, let alone a whole day. From the moment we wake up until we go to sleep, the phone is constantly in our hands and right in front of our eyes for hours on end. While this inevitably affects our vision, keeping the display brightness at the maximum level can cause further damage to the phone and battery. It is, therefore, advisable to avoid keeping the brightness at the maximum setting. Today, we will look at the potential downsides of using full brightness.
The downsides of keeping display brightness at the maximum level
Impact on the eyes: Keeping the phone at full brightness has a negative effect on your eyes. Viewing the phone at maximum brightness for extended periods can cause your eyes to become dry. Within a few days, your vision may become blurry, and you might experience headaches. If you continue using the phone at this brightness level, you could eventually need glasses within a few months. Additionally, the blue light emitted by the phone can disrupt your sleep. Blue light inhibits the release of melatonin, the hormone that signals to the brain that it is time to sleep. Therefore, it is best to keep the display brightness low.
Full brightness is the enemy of the battery: Maximum display brightness places an extra load on the battery. If you are in the habit of using your phone at full brightness, you might find yourself needing to charge it twice a day. Charging the battery twice daily affects its lifespan. The phone also heats up during charging, and in hot weather, this heat can even cause the battery to swell. Consequently, you may soon find yourself needing to replace the battery. This is why it is advised not to keep the brightness at the maximum level—to help preserve battery life.
Risk to the display—If you are using a phone with an OLED or AMOLED display, keeping the brightness at the maximum level poses a risk to the screen as well. Maximum brightness increases the likelihood of "screen burn-in." This means that continuous use at high brightness can leave permanent marks on the phone's screen. To prevent this, keep the brightness level lower. If you tend to forget to adjust the brightness, consider enabling "Auto-brightness" or "Dark Mode."
