To make a Samsung Galaxy A57 last longer between charges, use Power saving when you need extra runtime, restrict background activity only for apps you rarely use, and check which apps are consuming the most battery. If your phone offers a Motion smoothness setting, Standard may reduce display demand in exchange for less-smooth scrolling. These controls involve trade-offs—especially for notifications—and Samsung does not publish a specific number of extra hours they provide on the A57.
Use Power saving when you need more runtime
Samsung describes Power saving as a way to extend usage time. Turn it on when you expect to be away from a charger or need to stretch the remaining charge. Because some apps may not send notifications while Power saving is active, check that essential messaging, security, and work-alert apps still behave as you need.

The exact menu path and available options can vary by software version and region. Look for the current Power saving control in your A57’s battery settings rather than relying on a path from another Galaxy model. Samsung’s Galaxy Z Fold6 manual describes general Samsung battery controls, but it is not the A57 manual.
Restrict background activity selectively
Background usage limits can reduce activity from apps you do not use often. Review the list and limit only apps that do not need to run in the background. Restricting an app can delay notifications or interfere with background work, so leave limits off for apps whose timely alerts or activity matter to you.

Samsung’s product page lists an Android 16 User Manual, version 1.0, dated March 26, 2026. Since the detailed menu guidance cited here comes from another Galaxy model, confirm the labels and available choices on your own A57.
Find apps using unusually large amounts of battery
Check the phone’s battery-use information for apps that consume an unexpectedly large share of power. 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 information to investigate unusual consumption rather than closing or restricting every app indiscriminately; some background activity is necessary for the alerts and services you rely on.

Consider Standard Motion smoothness
If Motion smoothness is available on your A57, Standard is an option for reducing display demand. Samsung says Standard uses a standard refresh rate in normal situations to conserve battery power. Scrolling may feel less smooth than with a higher or adaptive refresh rate, so choose the setting that best balances runtime and display feel. Verify that the option appears on your phone; the cited refresh-rate guidance is from a different Galaxy manual.

Samsung lists the Galaxy A57 5G with a 5,000 mAh typical battery capacity and a 4,905 mAh rated minimum capacity. Neither figure predicts how long a particular charge will last: Samsung says runtime varies with network conditions, usage patterns, features and apps, calls and messages, charging history, and other factors.

Samsung’s “2 days” claim is an estimate, not a guarantee for every owner. It is based on an average usage profile compiled by UX Connect Research and an independent assessment in the UK 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. See Samsung’s Galaxy A57 5G product page for the published specifications and claim.
No A57-specific figure establishes how many minutes or hours any individual setting saves. To judge whether a change helps, compare battery use across similar days and conditions rather than assuming a universal gain.
