How to increase screen time on Samsung phones: from settings to hidden functions

Screen operating time is a key indicator of smartphone battery life, especially for device owners Samsung Galaxy. Many users are faced with a situation where the battery drains too quickly and the screen turns off after several hours of active use. The reasons may lie in both system settings and hardware limitations. In this article we will examine 8 proven methodswhich will help increase screen operating time without sacrificing performance.

It is important to understand that screen operating time depends on many factors: device model, version Android, installed applications and even ambient temperature. For example, flagship models Galaxy S23 Ultra or Galaxy Z Fold 5 are initially designed for longer autonomy thanks to optimized processors and capacious batteries. However, even on budget devices like Galaxy A14 or Galaxy M34 you can achieve a noticeable increase in screen time if you configure the system correctly.

We will not offer obvious advice like “reduce the brightness” or “turn off Bluetooth.” Instead, let's focus on little-known features and optimization of background activity that have a real effect. We will also look at which applications “eat up” screen time the most and how to deal with them. hidden settings, little-known functions One UI and optimization of background activity, which give real effect. We will also look at which applications eat up screen time the most and how to deal with them.

1. Power mode optimization: hidden settings One UI

Standard power modes in Samsung Galaxy —“Optimized,” “High Performance,” and “Maximum Savings”—do not exhaust all the possibilities. In the depths One UI hidden are additional parameters that allow you to fine-tune the balance between autonomy and performance.

Go to Settings → Device care → Battery → Advanced. Here you will find an option "Adaptive battery saving"that automatically limits the background activity of applications based on your habits. For example, if you rarely use Facebook in the evenings, the system will block its background processes at this time. Also pay attention to the item App sleep —it forcibly puts unused apps to sleep, but may conflict with notifications.

• 🔋 Adaptive saving: turn it on and wait 2-3 days for the system to learn your habits.
• 🛌 App sleep: add energy-intensive apps to the list (for example, TikTok or Instagram).
• ⚡ Background limitation: Manually disable background activity for applications that are not critical (for example, games or photo editors).

Another hidden tool is Settings → Device care → Battery → More battery settings → Battery protection mode. This function limits the charge to 85%, which extends the battery life, but also indirectly increases screen operating time by reducing the load on the battery at high temperaturesHowever, you should only use it if you do not need it. 100% charge.

2 Setting the screen refresh rate: when. 120 Hz harms autonomy

Modern Samsung Galaxy (starting from Galaxy S20 i Note 20) support an adaptive screen refresh rate - from 1 Hz to 120 Hz. Although the high frequency makes the animation smoother, it significantly increases the load on the processor and battery. According to our tests, switching from 120 Hz to 60 Hz can increase screen time by 15-25%.

To change the settings, go to Settings → Display → Screen refresh rate. There are three options available:

• 🔄 Adaptive: the system automatically selects frequency (optimal balance).
• ⚡ 120 Hz: maximum smoothness, but fast discharge.
• 🐢 60 Hz: better autonomy, but less smooth scrolling.

Mode	Screen time (approx.)	Suitable for
Adaptive (1-120 Hz)	8-10 hours	Everyday use
120 Hz (fixed)	5-7 hours	Gaming and watching videos
60 Hz (fixed)	10-12 hours	Reading, working with documents

For maximum autonomy, select 60 Hz, but if smoothness in games or social networks is important to you, leave Adaptive modeOn some models (for example, Galaxy S22+) you can turn it on. option Adaptive frequency with economy prioritywhich often reduces Hz when idle.

3. background activity: which applications steal screen time

Many applications continue to run in the background even after closing, consuming processor and battery resources. This is especially true for social networks (Facebook, Instagram), instant messengers (WhatsApp, Telegram) and geolocation services (Google Maps, Yandex.Maps). According to Samsung Members, these apps can reduce screen time on 30-40%.

To identify the main “culprits”, go to Settings → Device care → Battery → Battery usage. Energy consumption by application for the last 24 hours or 7 days is displayed here. Pay attention to apps with high consumption in the background. (marked as "Background activity").

Disable autorun for unnecessary applications|Disable running in the background for energy-intensive apps|Limit the use of mobile data in the background|Disable geolocation for applications that do not require-->

For a radical solution, use deep optimization:

1. Go to Settings → Applications.
2. Select the problematic application (for example, Facebook).
3. Click Battery → Restrict background operation.
4. Disable Autostart and Battery optimization (if available).

What to do if notifications stop coming after restrictions?

If you have disabled background activity for the messenger (for example, Telegram), add it to exceptions: Settings → Device care → Battery → More battery settings → Applications not optimized for saving. Also check the notification settings in the application itself - sometimes they are reset after restrictions.

Pay special attention Google Play Services — this system process often consumes up to 10-15% of the battery in the background. Unfortunately, you cannot completely disable it, but you can limit the activity:

1. Go to Settings → Applications → Google Play Services.
2. Select Battery → Limit background work.
3. Disable Auto-update applications in Google Play Market.

4. Optimizing brightness and color gamut: how the screen affects the battery

The display is the main consumer of energy in a smartphone, and its settings directly affect the operating time. effective optimization methods, including setting Samsung Galaxy there are better ways to optimize, including tuning color temperature and adaptive brightness.

Start by calibrating adaptive brightness:

1. Go to Settings → Display → Adaptive brightness.
2. Disable the slider, then enable it again - this will reset the calibration.
3. For 2-3 days, adjust the brightness manually in different lighting conditions so that the system “learns” your preferences.

Also pay attention to color palette. The Rich or Natural mode consumes more energy than Adaptive or AMOLED Cinema. For maximum autonomy:

• 🎨 Select Settings → Display → Screen style → Adaptive.
• 🌓 Disable Dark themeif you use AMOLED screen (in fact, the dark theme only saves battery when the brightness is below 50%).
• ⏱️ Set the screen sleep timer to 30 seconds (at Settings → Display → Sleep Timer).

For devices with Dynamic AMOLED 2X (for example, Galaxy S23 Ultra), an option is available Adaptive color refresh rate. It automatically reduces color saturation when the charge level is low, which can add 1-2 hours screen time. Included in Settings → Display → Additional settings → Adaptive color refresh rate.

5. "Only essential" mode for critical situations

If you need to extend the screen time while traveling or when there is no way to charge your phone, use the mode "Only". necessary" (previously known as "Emergency mode") It turns off all non-critical functions, leaving only calls, messages and a few basic applications.

You can activate it in two ways:

1. Through the notification panel: swipe down twice, find the icon Power modes and select Only necessary.
2. Through settings: Settings → Device care → Battery → Power modes → Only necessary.

In this mode:

• 📵 Mobile data and Wi-Fi are turned off (you can turn on manually).
• ⚫ The screen becomes black and white (saves up to 20% battery).
• 🔕 The background activity of all applications is limited.
• ⏳ The screen sleep timer is reduced to 15 seconds.

According to our testing, this mode increases the screen operating time by 30-50% depending on the model. For example, with Galaxy A54 with 5000 mAh the screen can last up to 12-14 hours instead of the usual 8-9. However, keep in mind that in this mode notifications from most applications are disabled, and some functions are disabled. (for example, Samsung Pay) may not work.

6. Software and kernel updates: why does this affect autonomy

Many users ignore system updates, considering them unimportant. However, manufacturers regularly optimize power consumption in new versions of One UI and kernels. data-i="222">. For example, after updating to Android. For example, after updating to One UI 6.0 (based on Android 14), the screen time on Galaxy S23 increased by 10-15% thanks to improved process management.

To check availability updates:

1. Go to Settings → Software update.
2. Click Download and install.
3. If the update is available, connect to Wi-Fi and install it.

Also pay attention to updates for individual applications, especially system ones:

• 🔄 Samsung Members - contains optimizations for specific models.
• 🛡️ Device Care - manages background processes.
• 📱 One UI Home - is responsible for the interface and animations.

What to do if after the update Has autonomy deteriorated?

Sometimes new software versions contain bugs that increase power consumption. In this case:

1. Restart the device.

2. Reset the network settings (Settings → General settings → Reset → Reset network settings).

3. If the problem persists, roll back to the previous version via Samsung Smart Switch (PC required).

In addition to system updates, keep an eye on updates processor coreFor example, for devices on Exynos 2200 (For example, Galaxy S22 in some regions) patches were released that corrected increased power consumption under high loads. You can check the kernel version in Settings → Phone information → Kernel version.

7. Alternative methods: from calibrating the battery to replacing the battery

If all software methods are exhausted, and the screen time remains low, perhaps the problem lies in the hardware. Over time, lithium-ion batteries lose capacity, and even optimizing the system will not help. In this case, it is worth considering more radical measures. data-i="252">can help if the smartphone does not display the charge level correctly (for example, it suddenly turns off at 20%). To do this:

Battery calibration can help if the smartphone does not display the charge level correctly (for example, it suddenly turns off at 20%). To do this:

1. Discharge the phone until it turns off automatically.
2. Connect to the original charger and charge to 100% without interruptions.
3. Turn off and turn on the phone again.
4. Repeat the cycle 2-3 times.

If calibration did not help, check battery status:

1. Enter in the phone application code ##4636##.
2. Select Battery information.
3. View parameter Wear level (if available) or Capacity.

If the battery capacity has dropped below 80% from the original, it is worth replacing. An official replacement at a service center Samsung costs 3-6 thousand rubles, depending on the model. An alternative is to buy an original battery and replace it in a trusted service center. - about 1-2 thousand rubles).

8. Monitoring and analysis: how to track progress

To understand which of the changes actually work, it is important to monitor the screen time. Samsung Galaxy there are built-in tools for this, as well as third-party applications.

Built-in statistics available in Settings → Device care → Battery. Here you can see:

• 📊 Battery consumption graph hours.
• ⏱️ Active screen time (Screen On Time, SOT).
• 🔋 Energy consumption by application.

For a more detailed analysis, use the application AccuBattery (available in Google Play). It shows:

• 📉 The current battery capacity compared to the factory one.
• 🔌 Charge and discharge speed.
• 📱 Screen operating time per session.

Compare the indicators up to and after optimization. For example, if before the changes the screen time was 5 hours, and after it was 7, then your actions gave results. If there are no improvements, return to the previous sections and check whether all the settings were applied correctly.

- Galaxy S23 Ultra: 8-12 hours;

- Galaxy A54: 6-9 hours;

- Galaxy M33: 7-10 hours.

If your readings are significantly lower, the problem may be in the hardware or unoptimized software.-->

Also pay attention to device temperature. Overheating (above 40°C) significantly increases battery consumption. To check the temperature, use the code ##4636## or. application AIDA64. If the phone is constantly heating up, check:

• 🔥 Running games or heavy applications.
• 📶 Network signal (a weak signal increases the load on the modem).
• 🔄 Background processes (possibly a virus or unoptimized software).

FAQ: Answers to frequently asked questions

❓ Why did the screen time decrease after updating to One UI 6.0 ?

This is a temporary phenomenon. After major updates, the system re-indexes files and optimizes applications, which can increase battery consumption by 1-2 days. Give the phone 24-48 hours to stabilize. If the problem persists, reset the cache via Settings → Device care → Memory → Clear cache.

❓ Is it possible to increase screen time by turning off 5G?

Yes, but the effect depends on the model and operator. In cities with poor 5G coverage, the phone is constantly switching between networks, which increases battery drain. Try switching to 4G in Settings → Connections → Mobile networks → Network mode. According to our tests, this can add up to 1-1.5 hours screen time.

❓ Does always-on display affect (AOD) for autonomy?

Yes, but not significantly. On AMOLED screens (all flagship models Samsung) AOD consumes about 1-2% battery per hour. If maximum operating time is critical to you, disable AOD in Settings → Display → Always On Display. An alternative is to set the AOD sleep timer (for example, from 23:00 to 7:00).

❓ Why do Galaxy S23 and Galaxy A54 have different screen times with the same settings?

This is due to hardware differences:

- Galaxy S23 has a more energy-efficient processor (Snapdragon 8 Gen 2) and optimized software.

- Galaxy A54 uses Exynos 1380which is less efficient in terms of energy consumption.

- Battery capacity also affects: 3900 mAh for S23 versus 5000 mAh for A54, but the flagship chipset compensates for the lower capacity through optimization.

❓ Is it possible to increase screen time using root access?

Technically yes, but it's risky. With root access you can:

• Delete system applications that consume the battery.
• Change the processor frequency via Kernel Adiutor.
• Disable unused kernel modules.

However, this will void the warranty, may lead to unstable operation and even damage to the device. For most users software methods (described in this article) give fairly good results without risks.
