Modern smartphones have powerful processors and capacious batteries, but even they do not always survive until the evening without recharging. Often the reason lies not in battery wear, but in background software activity that the user does not even notice. Many apps, preinstalled by manufacturers or downloaded from stores, continue to run in the background, consuming valuable resources and heating up the device.
To restore the smartphone to its former autonomy, it is necessary to conduct a thorough audit of the installed software. There is a category of apps that can be safely removed without harm to the performance of the system, and there are also those that are better to get rid of for the sake of comfort. In this article, we will look at specific candidates for removal and explain why they drain the battery so much.
System junk and pre-installed software (Bloatware)
Smartphone manufacturers often enter into contracts with third-party application developers so that they are pre-installed on the device out of the box. These apps, known as bloatwarecan run in the background, collect statistics and consume energy, even if you have never used them.
Usually these are games, streaming services or utilities from brand partners Samsung, Xiaomi or Huawei. Removing such software is the first step towards optimization. However, you should be careful: some system components are critical for the operation of the interface.
⚠️ Attention: Before deleting system applications, make sure that they are not responsible for basic phone functions, such as calls, messages or network settings. An error can lead to unstable operation of the firmware.
Often on the list of energy eaters are analytics services and application stores that duplicate Google Play. If you do not use alternative stores, you can deactivate them. This will free up not only the charge, but also the RAM.
How to remove undeletable applications?
If the "Delete" button is inactive, try going to Settings → Applications → Special access → Usage access. Disable the permission for the unnecessary service and then remove it. In difficult cases, you will need an ADB command via a computer.
Social networks and instant messengers: hidden battery killers
Social networks are one of the main culprits of rapid discharge. Apps like Facebook, Instagram or VK continually track your location, check notifications, and refresh your feed in the background.
Even when the screen is off, these apps can wake up the processor dozens of times per minute. The geolocation function and automatic video playback have a particularly strong impact on consumption. Complete removal of such applications can increase the operating time of the device by 20-30%.
- 📱 Facebook - known for its high resource consumption and constant data synchronization.
- 📸 Instagram - actively uses the camera and Internet connection to preload content.
- 💬 Messenger - individual messenger applications often work more efficiently than built-in modules in social networks.
An alternative to heavy official clients are lightweight versions, such as Facebook Lite or web versions of services added to the home screen. They consume significantly less energy and memory space.
Launchers and widgets: beauty requires sacrifice
Custom launchers allow you to completely change the appearance of the interface Android, adding animations and gestures and unique icons. However, you have to pay for this beauty with increased battery consumption, since the launcher is a process that runs constantly.
Launchers with live wallpapers and complex transition animations are especially power-hungry. Every time you swipe the screen or open a menu, the processor is forced to wake up and process graphics. If your goal is maximum autonomy, it is better to return to the stock launcher.
It is also worth reviewing the number of widgets on the desktop. Widgets for weather, news or exchange rates require constant updating of data via the Internet. This creates a constant load on the radio module and processor.
⚠️ Warning: Live wallpapers can consume up to 15% more power in standby mode compared to a static image. It is recommended to use dark static wallpapers for AMOLED screens.
Use dark themes and black wallpapers on AMOLED screens. Pixels that display black color are simply turned off on such displays, which really saves battery power.
Games and entertainment content
Modern mobile games often use the capabilities GPU and CPU to the limit, which naturally leads to rapid discharge. But the problem is not only in the games themselves, but in related services that remain active after leaving the game.
Platforms like Steam or game service launchers can continue to download updates or synchronize achievements in the background. If you don't play daily, it's best to uninstall such applications and reinstall them as needed.
Streaming services for music and video are also a serious burden. Constantly buffering content and keeping the screen in playback mode quickly drains the battery. Removing the cache of these applications does not always help, since background services may remain active.
| Application type | Consumption level | Recommendation |
|---|---|---|
| Heavy 3D games | Critical | Remove or limit background work |
| Video streaming | High | Use only when connected to Wi-Fi |
| Social networks | Medium/High | Replace with Lite version |
| Messengers | Low/Medium | Disable notifications for group chats |
Games and Streaming services should be deleted if you do not use them daily. Re-installation will take a couple of minutes, and the battery savings will be noticeable.
Antiviruses and memory cleaners
Paradoxically, applications created to optimize the operation of a smartphone often become the cause of problems themselves. Third-party antiviruses and memory cleaners constantly scan the system, which creates a load on the processor and prevents the device from going into deep sleep.
Built-in protection Google Play Protect quite copes with basic security for the average user. Additional scanners often duplicate these functions, wasting resources. The situation is similar with applications for cleaning RAM.
Modern system Android itself effectively manages RAM. Forced memory clearing by third-party utilities forces the system to reload necessary processes, which ultimately wastes more energy than it saves.

How to find and remove the culprits
To accurately determine which applications to remove from Android to save battery, you need to use the built-in statistics. The system itself will tell you who has consumed the most energy over the past day or week.
Go to menu Settings → Battery → Battery Usage. Here you will see a detailed list of applications sorted by consumption percentage. If you see a app that you have not used, but it has consumed 10-15% of the charge, this is a candidate for deletion.
adb shell dumpsys batterystats --resetThis command resets the battery statistics via the computer, allowing you to start monitoring from scratch. After the reset, use the phone as usual for a couple of hours and check the statistics again.
For advanced users, it is possible to freeze applications without completely deleting them. This allows you to save the app data, but stop its execution completely. Tools like Titanium Backup (for root) or SD Maid help with this.
⚠️ Attention: The settings menu interface may differ depending on the version of Android and the manufacturer's shell (MIUI, OneUI, ColorOS). Look for sections with the words "Battery", "Energy Consumption" or "Power".
What to do if the application cannot be removed?
Try to disable it. In the application menu, select the one you want and click "Disable". The system will remove updates and hide the icon, stopping all processes.
Frequently asked questions (FAQ)
Is it safe to remove system applications via ADB?
Removing system applications via ADB is safe only if you know exactly the function of the package you are removing. Removing critical components such as com.android.phone or the system launcher can cause the phone to stop booting or lose connectivity.
Why does the battery drain even in airplane mode?
Even in airplane mode, operating system processes, background synchronization of some applications (if enabled for Wi-Fi), and display operation continue to consume energy. Also, the reason may be physical wear and tear of the battery.
Do you need to close applications manually through the multitasking menu?
No, constantly manually clearing the multitasking menu harms battery life. The Android system is optimized to keep frequently used apps in memory for quick launch. Forced closing forces the processor to waste energy on restarting them.
Which widgets are the most energy-intensive?
The most power-hungry widgets are those that require constant updating of data: weather, exchange rates, news feeds and social activity widgets. Static clock or calendar widgets consume a minimum of resources.
Will resetting to factory settings help save battery?
Resetting to factory settings can help if the cause of rapid discharge is a software glitch or application conflict accumulated over a long period of use. However, if the problem is physical battery wear or unoptimized software, resetting will not solve the problem radically.
