To make a Samsung Galaxy A57 last longer between charges, use Power saving when you need extra runtime, limit background activity only for apps you rarely use, and check battery usage for apps consuming unusually high power. If your phone offers Motion smoothness, switching to Standard may reduce display demand, at the cost of less-smooth scrolling. Because menus can vary by software version and region, confirm the labels on your A57.
1. Turn on Power saving when you need extra runtime
Power saving is Samsung’s built-in control for extending usage time. On your A57, look under Settings > Battery for the Power saving option; the exact menu path or label may differ with software and region. You can also check Quick settings for a Power saving tile.
Power saving may prevent some apps from sending notifications while it is active. After turning it on, check that essential messaging, security, and work-alert apps still behave as you need them to.
2. Restrict background activity selectively
Samsung’s general Galaxy guidance describes Background usage limits as a way to manage apps that run when you are not using them. Look for this setting in your A57’s battery settings, then consider limiting apps you rarely open and do not rely on for timely alerts or background work.

Avoid applying restrictions indiscriminately. An app that must deliver notifications promptly or perform work in the background may not function as expected when limited.
3. Find apps using unusually high battery
Review the battery-use information in Settings to identify apps consuming more power than you expect. Samsung’s Device care guidance also describes an Optimize now option that can close background apps or apps using an abnormal amount of battery. Use the figures and your own usage pattern to target specific problems rather than routinely closing or limiting every app.

4. Consider Standard Motion smoothness
If your A57 has a Motion smoothness setting, Samsung’s general guidance describes Standard as using a standard refresh rate in normal situations to conserve battery power. A higher or adaptive refresh rate may feel smoother, so choose Standard only if the trade-off suits you. Look under Settings > Display and verify the available choices on your phone; the detailed instructions available for this control come from a different Galaxy model, not the A57.
5. Judge changes under comparable conditions
Battery runtime can change with network conditions, apps, calls and messages, settings, and charging history. To see whether a change helps your A57, compare usage over similar periods with similar network and app activity. Samsung does not publish quantified A57-specific savings for these individual settings, so no particular control can be promised to add a set number of hours or a percentage.

What Samsung’s A57 battery figures mean
Samsung lists the Galaxy A57 5G with a 5,000 mAh typical battery capacity and a 4,905 mAh rated minimum capacity on its Galaxy A57 5G product page. Capacity figures do not predict an individual owner’s screen-on time or time between charges.
Samsung’s “2 days” battery statement is an estimate, not a guarantee. The company says it is based on an average usage profile compiled by UX Connect Research and an independent UK assessment conducted from January 8 through January 18, 2026. The assessment used pre-release SM-A576 devices with default settings on LTE and 5G Sub6 networks; it did not test 5G mmWave. Samsung also notes that actual battery life varies with network environment, usage patterns, features and apps, calls and messages, charging history, and other factors.
