Your Samsung phone already offers solid battery life, but a few smart setting tweaks can help it last even longer.
Samsung’s Galaxy smartphones are some of the best Android phones available today, thanks to their responsive and feature-rich software. But most Samsung phones — especially the flagships like the Galaxy S25 Ultra, Galaxy Z Fold 7, and Z Flip 7 — come with over-the-top features that you might not use daily.
If your new Galaxy phone isn’t lasting an entire day on a single charge, there are ways to make the most of what you have without hindering the user experience.
Here are seven ways to maximize the battery life on your Galaxy phone. Fret not — I won’t be Captain Obvious over here and recommend reducing the screen resolution or using your phone at a lower refresh rate. The recommendations on this list should bring quality-of-life improvements while maximizing your handset’s efficiency. Read on.1. Use Dark Mode
Most Samsung phones feature AMOLED displays, which can control individual pixels. So, when you use a dark theme or dark wallpaper, the part of the screen that needs to stay black won’t turn on those pixels. This, in turn, reduces screen power usage and makes your battery last slightly longer.
How to: Open the Settings app > Display. You’ll get two cards for Light and Dark. Tap on the Dark option. Alternatively, you can change the system wallpaper and continue using the light theme, but this will not have the same effect on battery as turning on the Dark mode.2. Toggle on Adaptive Brightness
This setting ideally comes activated out of the box, but some people turn it off because it’s not always accurate. However, over the years, Samsung’s ambient light sensor has improved in quality. Your Galaxy phone can reliably detect the lighting in your environment to automatically adjust the screen luminosity.
