One of the major problems reported by some users of the Galaxy S8 is the flash on the phone’s LED that is always ON. This issue is a bad situation made worse for those users whose phone battery is already poor. The LED flash on your Galaxy S8 will always make the battery drain faster.
As a matter of fact, the LED flash that is always on in some Galaxy S8 smartphones is actually not set to full brightness, but it’s a pretty bright light in the dark. This is the reason this flash could make your battery drain quickly.
This problem might look quite simple on the look, but it’s a very nagging problem especially if you do not have a portable battery charger for you to charge your drained battery anywhere and anytime. So it is very important that you find a solution to the issue before it starts to irritate.
Before you can find the solution, it is equally important that you optimize your battery usage so as to minimize the impact of the LED flash on your phone. There are various ways of saving your battery power as explained below.
