Modern smartphones have become incredibly powerful, but their autonomy often remains a bottleneck. Manufacturers implement aggressive battery-saving algorithms that can interfere with applications, slow down the processor, and limit background activity. Sometimes this optimization interferes with the normal operation of the device, causing delays in notifications or a drop in FPS in games.
Users often encounter a situation where the phone goes into power saving mode without the owner’s knowledge or is forced to maintain this status, despite sufficient battery charge. Disabling this feature returns the smartphone to its former sharpness and allows applications to work at full capacity. However, it is worth understanding that Android different devices may have unique shells, where the path to the desired setting is different.
In this article we will look in detail at how to deactivate the power saving mode on different versions of the operating system and for popular brands. You will learn not only about standard methods, but also about hidden settings that can affect resource consumption. Are you ready to return your gadget to maximum performance?
Understanding how the battery saving mode works
The power saving mode is a set of software restrictions designed to extend the operating time of the device on a single charge. When this feature is active, the system reduces the clock speed processor, dims the screen brightness, and disables background data synchronization. For an ordinary user, this may look like a sudden “braking” of the interface.
There are several levels of battery protection. The basic level simply limits background processes, while the extreme mode can actually turn the smartphone into a “dialer”, disabling mobile data and most applications. It is important to distinguish between automatic activation when the battery is low (usually 15-20%) and manual activation by the user.
Some shells, such as MIUI or OneUIhave their own power managers that work more aggressively than stock. Android. They can “kill” instant messenger processes, causing messages to arrive late. Understanding these mechanisms helps you properly configure the device to suit your needs without critically sacrificing battery life.
⚠️ Attention: Completely disabling all energy-saving functions will lead to accelerated battery drain. If you are planning a long trip without the possibility of recharging, it is better to leave the automatic mode on.
Universal method through quick settings
The fastest way to check the status of energy saving is to use the notification shade. Swipe down from the top edge of the screen to expand the Quick Access Toolbar. On some devices, double swipe or click on the pencil icon to edit tiles.
Look for an icon in the form of a battery or lightning bolt. If it is highlighted with an active color, it means the mode is enabled. Just click on it to deactivate. If you don't see the tile you need, it may be hidden in the additional interface editing menu.
This method works on most versions Android 8.0 and higher. However, it only toggles a global toggle switch and does not always cancel individual restrictions for specific applications that could have been previously configured manually.
- 🔋 Swipe down twice to fully open the panel.
- ⚡ Find the "Battery Saver" or "Battery Saver" icon.
- 🚫 Click on the active one icon so that it becomes gray.
- 🔍 If there is no icon, click "Change" or the pencil icon.
Deep configuration in the system menu
For a more detailed configuration, you need to go deep into the system settings. The path may differ slightly, but the logic remains the same for all devices based on Android. Open the "Settings" application and find the section related to power.
In clean Android (Pixel, Motorola) this section is called "Battery". In it you will see the “Power Saving Mode” switch. Turn it to the "Off" position. Also here, the “Adaptive mode” setting is often available, which learns your habits.
Pay attention to the “Battery optimization” item. Once you open it, you will see a list of applications. Make sure that the apps you need (messengers, mail) are not under strict control of the system. To do this, select the application and set the value to "Do not optimize" or "No restrictions".
Settings → Battery → Power saving mode → OFFIf the power saving mode switch is grayed out, check whether the device is connected to a charger. On some models, the function is blocked when charging.
Disablement features on Samsung Galaxy
The company's devices Samsung use a shell One UI, which is famous for its advanced power management. There is not only a normal mode, but also a “Maximum Energy Saving” mode, which radically changes the interface. To remove restrictions, go to Settings → Device Maintenance → Battery.
In this menu you will find two main switches. The first is responsible for standard savings, the second for extreme. Make sure both are turned off. Also in the "Background Restrictions" menu you can check which applications are limited in the background.
An interesting feature is "Adaptive Power Mode". It uses machine learning for optimization. If you feel that the phone is running slowly, try temporarily disabling this option, although for most users it is useful.
| Mode type | Impact on the system | Where to disable |
|---|---|---|
| Energy saving | Limits background, reduces the CPU frequency | Settings → Battery |
| Maximum savings | Disables the Internet, changes the launcher | Settings → Battery → Max. saving |
| Adaptive mode | Smart habit learning | Settings → Battery → Power modes |
⚠️ Attention: On Samsung smartphones, the "Battery Protection" function may limit the charge to 80-85%. This is not a power saving mode, but does affect the available capacity. It is disabled in the same battery menu.
☑️ Checking Samsung settings
Specifics of Xiaomi, Redmi and POCO
Shell MIUI (and new HyperOS) is known for its aggressive policy towards background processes. Here it is important not only to turn off the general mode, but also to configure the behavior of individual applications. Go to Settings → Battery.
At the top of the screen you will see the “Battery Saver” switch. Turn it off. Next, go to "Apps & notifications" or "Advanced settings" to find auto-start controls. The system Xiaomi by default prevents many apps from starting on their own.
For each important application (WhatsApp, Telegram, banks), go to the battery settings inside the application card. Select the "No restrictions" option. This is critical for timely receipt of notifications on devices of this brand.
Users often complain that the phone “falls asleep” too quickly. In this case, it is worth checking the screen lock settings and display timeout, as they are also part of the overall energy saving strategy.
Hidden setting in MIUI
In the "Security" application → Battery → Gear (Settings), you can disable "MIUI Optimization", which sometimes solves problems with background work, but may reduce autonomy.
Problems with automatic switching on
It happens that you turn off the mode, but after a while it turns on again. Most often, this is triggered by the default automatic rule. The system is configured to turn on saving when a certain percentage of charge is reached, usually 15% or 20%.
To change this behavior, find the "Turn on automatically" or "Schedule" item in the battery menu. Here you can set your trigger threshold or completely disable automation. Also check to see if there are any active sleep profiles that are activated at night.
Sometimes the culprit is a third-party cleaner or antivirus application that forces the economy mode to “optimize” the system. Check the settings of such utilities and add them to exceptions if you trust them.
- 🤖 Check the "Enable automatically" item in the battery settings.
- 📅 Disable the schedule for turning on the mode by time.
- 🧹 Check third-party applications to clear memory.
- 🔋 Make sure the charge sensor is working correctly (calibration).
Impact on performance and games
For gamers, power saving mode is the main enemy of high power FPS. When activated, the system throttles (reduces frequencies) the processor and graphics accelerator, which leads to jerks in games. Disabling the mode is necessary for comfortable play in heavy projects.
Many modern smartphones have a special “Game Mode” or “Game Turbo”. Make sure it's active and set to performance rather than economy. In the game mode settings there is often a "Performance Priority" switch.
It is worth noting that even with the power saving mode turned off, the phone may overheat and drop frequencies. This is a physical limitation, not a software one. In such cases, removing the case or using a cooler helps.
⚠️ Attention: Long-term operation at maximum performance without a power saving mode leads to increased heating of the case and accelerated battery wear. Take breaks from heavy games.
Disabling power saving does not increase battery capacity, but only allows the system to use available resources by 100%, which inevitably reduces battery life.
Advanced developer settings
For advanced users, there is a "For Developers" menu. To get there, you need to click on the build number 7 times in the "About phone" section. This menu contains items that affect energy saving at a deep level.
Find the “Stay awake” item. If it's on, the screen won't go dark while charging, preventing you from going into deep sleep. Also check the “Background processes” settings, making sure that there is no restriction “No more than 1 process.”
However, be careful: incorrectly setting the developer options can lead to unstable operation of the system. Change only those values whose purpose you are sure of.
Settings → About phone → Press 7 times on "Build number" → For developersIf after all the manipulations the phone still discharges quickly, check the battery consumption statistics. Perhaps one specific application is consuming resources abnormally, and it is easier to remove or freeze it.
Why does the power saving mode turn on itself at 20% charge?
This is standard system behavior programmed by the manufacturer to prevent the phone from suddenly turning off. You can change this threshold or disable automatic activation in the battery settings in the "Automation" or "Schedule" section.
Does disabling the mode affect the charging speed?
No, the power saving mode affects the energy consumption, and not the speed of its receipt. However, when the mode is turned on, the phone may heat up less during charging, since the processor operates at lower frequencies, which indirectly can make charging a little more efficient in terms of efficiency, but the difference is minimal.
Is it possible to completely remove the system power saving mode?
Without obtaining root access and modifying system files - no. This is part of the operating system kernel Android. You can only disable its activation, but the function code itself will remain in the firmware.
Why did the phone begin to heat up after disabling the mode?
Without power consumption restrictions, the processor and modem operate at maximum frequencies, processing more background tasks. This is a normal reaction. If the heating seems excessive, check to see if an app is stuck in a reboot loop.
Are power saving settings reset after a reboot?
No, your settings (turn off mode, change thresholds, app exceptions) are saved in the device memory and remain active after a reboot until you manually change them again or do not reset the phone to factory settings.
