15 tips and tricks to improve battery life on the Samsung Galaxy S8 and S8+



There is an interesting trend going on with modern smartphones over the last several years – big advancements are made in nearly all hardware and software areas, but battery life always seems to improve at a slower pace.

This peculiar progression can be clearly observed in 2017 – so far, some of the biggest Android manufacturers came out with flagships that have thin bezels, large displays, and beefed-up performance specs.

Samsung has been at the forefront of these developments, as the company's Galaxy S8 and S8+ handsets feature a beautiful new design with minimal bezels, huge 5.8-/6.2-inch displays, and extremely powerful chipsets.

While the changes are undoubtedly welcome, isn't it a bit sad that these expensive contemporary flagships can't even compete with cheap smartphones in the battery department?


Compared to other flagships, the two phones actually do really well when it comes to battery life. 

The Galaxy S8 with its 3,000 mAh cell scored 8 hours and 22 minutes in our dedicated test, while the larger 3,500 mAh battery on the S8+ clocked in at exactly 8 hours.

All of this may sound great, but it's still noticeably less than the 2017 versions of the Samsung Galaxy A3,A5 and A7, which all achieved scores of above 11 hours.


Odds are that the Galaxy S8/S8+ will get you through a busy day with some juice to spare, but what can be done if you'd like to get even more time between charges?

Below, we've compiled a number of tricks and tips that will improve the battery life on Samsung's latest and greatest. Some of them are obvious, while some are a bit more sneaky.

Nobody expects you to stick with all of them, but you can test them out and decide what works for you. A good rule of thumb here is: If one of the techniques takes away features that you consider as essential, don't bother using it.
