What is it and why are new devices cluttered with it?
Bloatware refers to pre-installed applications on a device that usually provide no benefit to the user but consume valuable system resources: memory, processing power, and battery life. While they are not typically harmful in the literal sense, they act as „digital ballast”. Manufacturers and service providers install these applications for several strategic reasons:- Financial Partnerships: Software developers (e.g., antivirus or game developers) pay device manufacturers to have their products pre-installed. This reduces the cost of equipment but shifts the burden onto the user experience.
- Eco-system Development: Manufacturers (e.g., Samsung, Xiaomi) aim for you to use their browser, calendar, or cloud services instead of standard Google solutions, thus tying you to their brand.
- Carrier Interests: When purchasing a phone from a mobile carrier, you often receive a device with pre-installed self-service, TV, or partner applications.
From Annoying Ads to Unnecessary Tools
Not all pre-installed applications are the same. They can be categorized into several types based on their function and intrusiveness:Trialware
This is most commonly found on Windows computers. The user finds a pre-installed antivirus (e.g., McAfee or Norton) or an office suite with a 30-day free trial. After the trial period, the program becomes inactive but continues to run in the background and demands payment.Adware
This is the most aggressive form, more often found on budget-class phones. Manufacturer-installed weather or news apps can display pop-up ads in the notification bar, disrupting work and consuming data.Duplicate Tools
This is a situation where there are two applications to perform the same function on the system. For example, on an Android phone, you have Google Photos, but the manufacturer additionally installed its Gallery. Both applications index photos, both send notifications, and both use battery power.Where is the bloatware problem most acute?
Android Ecosystem
This is the platform where the problem is most pronounced. Manufacturers use their user interfaces (e.g., One UI, MIUI) that are „cluttered” with their services. Additionally, if the phone was purchased from a carrier, it may have applications that cannot be removed in the standard way.Windows Computers
A new laptop often comes with manufacturer (HP, Lenovo, Dell) utility programs designed for driver updates, but they often operate inefficiently. The Start menu often contains „advertised” links to TikTok, Instagram, or games.iOS and macOS (Apple)
The Apple ecosystem is the cleanest. There are no third-party (carrier or advertising client) applications. However, users may still find unnecessary Apple applications, such as Stocks, Tips, or GarageBand, which take up space.Benefits for Performance, Battery, and Privacy
By getting rid of unnecessary ballast, you gain tangible benefits:- Increased Speed and More RAM: Fewer background processes mean that the processor and RAM can be allocated to the tasks you are performing, not those imposed by the manufacturer.
- Longer Battery Life: Every application running in the background, checking servers or searching for updates, uses energy. Removing them can significantly extend operating time.
- Privacy Protection: Most free or ad-supported applications collect data about user behavior. By removing them, you prevent unnecessary data leaks.
- Freed Space: Although modern devices have plenty of memory, 2-3 GB taken up by unused games or applications can be used for photos or videos.
From Simple Disabling to ADB Commands
Level 1: Uninstall or Disable
Many third-party applications (e.g., games) can be simply deleted through settings. However, for system applications, the „Uninstall” button is often inactive. In this case, look for the Disable button. This stops the application from running and hides its icon, although the files remain in memory. This is a safe and recommended method.Level 2: Removal via ADB (No Root)
If the application cannot even be disabled, you can use the ADB (Android Debug Bridge) tool on your computer. This allows you to remove applications for the current user without damaging the system core.- Enable „Developer Options” and „USB Debugging” on your phone.
- Connect the phone to the computer and use a tool like Universal Android Debloater (UAD). This is a graphical interface that shows a list of applications and recommendations on what is safe to delete.
- Or use the command in the terminal: adb shell pm uninstall –user 0 <package_name>
PowerShell and Specialized Tools
Manual Removal
Most applications can be removed through Settings > Apps > Installed Apps. However, integrated Windows applications (e.g., Xbox Game Bar, Cortana) may require PowerShell commands (e.g., Get-AppxPackage).Automated Tools
For safe and quick cleaning, it is recommended to use the O&O AppBuster tool. It is free, requires no installation, and clearly shows which applications are system (Microsoft) and which are third-party. The program allows you to remove selected applications with one click and, importantly, create a system restore point before doing so.Simpler Management and Offload Feature
iOS (iPhone/iPad)
Apple allows you to delete most of its integrated applications (e.g., Stocks, Music, Mail) simply by long-pressing the icon and selecting Remove App. If you want to save space but keep the data, use the Offload App feature (Settings > General > iPhone Storage). This deletes the application file but leaves the icon and documents – tapping it will redownload it.macOS
Most applications can simply be dragged to the trash. However, system applications (Safari, Mail) are protected by system integrity (SIP) and it is not recommended to delete them, as they take up little space but are critical for OS operation.What You Need to Know Before Starting
While removing bloatware is beneficial, proceed responsibly:- Make Backups: Always back up important data before using ADB or PowerShell tools.
- Do Not Remove What You Do Not Understand: If the application name contains the words „System”, „Framework”, „Driver”, or „Boot”, removing it may damage the device’s functionality. Use community-verified lists.
- Warranty: Standard disabling or removal of applications via ADB does not void the warranty. However, „rooting” or „jailbreaking” the device to delete deeply integrated applications may void the warranty.
- Updates: After major system updates, some removed applications may return. This is normal – just repeat the process.
