The Samsung Galaxy A54 is a smartphone appreciated for its balance between performance, battery life, and price. Despite a well-sized battery, some users experience a rapid battery drain during the day. However, there is a discreet feature, not well-documented in the usual menus, that can extend your active screen time by about 60 minutes daily depending on usage.
This mode is not a simple brightness setting or a drastic display reduction: it is a fine-tuning of system behavior, acting on several parameters in the background.
Unlike usual modes like basic or extreme power saving, this hidden setting is not prominently displayed in the settings. It works by optimizing multiple system behaviors simultaneously, for example by recalibrating resource management when the screen is on.
According to tests conducted by specialized sites, this mode can extend the active screen time by 45 to 75 additional minutes per day for mixed use (web browsing, social networks, short videos), simply by limiting non-essential background activities.
This gain is often noticeable from the first hours of use after activation, especially for prolonged screen-on sessions.
This mode does not appear in the default visible sections of the settings. Here’s how to access this option:
Depending on the version of One UI, the title may vary slightly, but it generally contains the words “screen” and “optimization.” Once activated, the system will ask you to confirm the restart to apply the in-depth settings.
This setting modifies several background behaviors without affecting the visual quality of the screen:
Stricter management of background apps
Even without closing your apps, the system more aggressively limits unnecessary activities when the screen is on. This reduces processor load and thus energy consumption.
Adjustment of refresh rate
The Galaxy A54 has a 120 Hz screen. The hidden mode automatically reduces the frequency in certain situations where it is not essential, while maintaining a smooth experience to the eye. It is a smarter optimization than simply manually switching to 60 Hz.
Reduction of superficial animations
Without you really noticing, minor system transitions and animations are disabled or simplified, which decreases GPU and CPU load.
These combined modifications explain why the screen stays on longer without affecting brightness or significantly reducing visual comfort.
Users interested in this trick often wonder if the gain is significant or anecdotal. Data observed over several days of use shows:
These figures are not fixed, as they depend on individual behavior. However, even an improvement of one hour per day can allow you to complete a full day without recharging, which represents real progress for a mid-range smartphone.
Although any Galaxy A54 owner can activate this setting, certain usage profiles benefit more significantly:
For very light use, the gain will be less, as the battery is not heavily taxed. However, for mixed or sustained use, the difference becomes noticeably perceptible.
This hidden mode does not replace but complements the classic settings such as:
You can certainly activate this hidden setting alongside other options. In most cases, the effects are cumulative, as each setting acts on different aspects: one on overall consumption, the other on what happens while the screen is on.
However, it is recommended to avoid activating all extreme modes simultaneously. Some combinations may make the experience less pleasant, for example by slowing down animations too much or excessively limiting notifications.
There are a few situations where activating this mode may be less appropriate:
If you use performance-demanding applications such as resource-intensive games or video editing. In these cases, the system may reduce certain resources to prioritize battery life, which may slightly slow down these applications.
If you want to enjoy the screen at full 120 Hz frequency at all times. The mode sometimes favors lower frequencies to save energy.
In these specific cases, it may be preferable to deactivate the setting, or to keep it active only when you feel the battery is running low at the end of the day.
