What is Android memory?
Android always uses some memory because the firmware itself consumes around 6.80GB. These are the programs installed by the manufacturer, which can be large compared to standard applications. Removing them typically involves connecting the phone to a computer and using Linux tools. The remaining cache is usually about 8.3GB. This space is reserved for temporary data and services. Running a pure Android without additional software can help reduce strain during low performance situations.
You're focusing on storage space rather than RAM. Firmware includes the operating system and preinstalled applications. A standard Linux or Windows setup typically requires 5-10GB. Most systems also include files you have locally that aren't categorized as images, videos, audio, or documents—often in large quantities. Use a proper file manager to inspect your storage, sort by size, and manage it effectively.
It covers the entire partition, encompassing both system files and user data. The exact setup varies based on your ROM and device model—there’s no universal solution. It involves areas like /data and a few other folders in your phone’s storage, which may come from AOSP or your manufacturer. Root access is necessary to remove any system components, but be mindful you risk damaging the device. Files outside /data and /system won’t be included, and caching isn’t accounted for. Comparing Android to traditional desktop distros isn’t straightforward today, as each platform now has a substantial amount of device-specific files in memory (like RIL, Bluetooth, GPS) that demand significant RAM. Using it may lead to reduced performance, especially with camera quality, since manufacturers often run proprietary image/video processing software.
Firmware 6.79 GB serves as the main operating system, along with drivers for different cameras, chipsets, and other components. Additional elements likely include various bundled programs and libraries accessible via Google Play, eliminating the need to repeatedly download large files each time you install an app. All these components reside in flash memory (32, 64, or 128 GB capacities). The RAM amounts—typically 3, 4, or 6 GB—support the OS by speeding up processes, storing frequently accessed files from flash, and running applications like WhatsApp, web browsers, etc. Programs often require significant disk space; for example, your Xiaomi Redmi 8 Pro alarm app consumes 78 MB, while "Find My Device" uses 38 MB, Messages takes 258 MB, Bluetooth setup apps 51 MB, the default photo app 40 MB, a calculator 22 MB, Google Drive 105 MB, and games can range from 150 to 200 MB each. Third-party tools like Discord use 175 MB, Reddit app 1 GB (consider clearing cache), YouTube player 1.22 GB (including cached media), and Kindle 240 MB even with a small collection of ebooks.
It's frustrating finding phone storage settings on Android, especially since they often remain unchanged. Every manufacturer and device can behave differently, like Samsung keeping it separate for performance reasons or even confusing users. Google’s approach seems to avoid those complications, though it can be unclear exactly where the data is stored.
