The Xperia XA1 is equipped with 3GB of RAM, which struggles under the weight of modern stock software. Lightweight custom ROMs use significantly less RAM at idle, leaving more memory available for multitasking and preventing aggressive app closures in the background. 4. Extended Battery Life
New apps and app updates often require newer Android versions, which the stock XA1 cannot run.

Sony’s original skin features duplicate apps, heavy background services, and telemetry trackers. A clean custom ROM completely removes this bloat. It frees up system RAM and relieves stress on the MediaTek Helio P20 processor. 3. Extended Battery Endurance
It is important to note that this ROM was last updated in August 2018 and was released in an early Alpha/Beta state. The developer noted significant problems with the installation process and cautioned that the ROM was largely untested and could potentially "brick your device". This is not a daily driver for most users.
If you are still holding onto your Xperia XA1 today, you are likely feeling the sting of planned obsolescence. The phone officially stops at Android 8.0 Oreo, a software version long abandoned by modern app developers. Performance stutters, the 2300 mAh battery drains faster than ever, and critical security patches are years out of date.
The stock Sony software on the XA1 is optimized for the hardware of 2017. As apps become heavier and security threats evolve, the old stock firmware becomes a bottleneck.
Finally, the ability to customize the user interface is a distinct advantage. The stock Sony interface is rigid, offering little room for personalization beyond wallpaper changes. Custom ROMs allow the user to tailor the device to their specific needs. Whether it is altering the navigation bar layout, customizing the status bar, overclocking the CPU for gaming, or under-volting to save heat, the user gains administrative control (root access) over their hardware. This transforms the Xperia XA1 from a consumer product with set limitations into a personalized tool that adapts to the user's workflow.
This post assumes the user has the single-SIM (G3121) or dual-SIM (G3112) MT6757 variant. The Snapdragon XA1 Plus is a different story.
Stock operating systems often suffer from background battery drain caused by telemetry and unoptimized manufacturer services. Custom ROMs offer granular control over app permissions, background data, and CPU governor profiles, which directly translates to better screen-on time. 5. Deeper Customization Options
, released in 2017, was a solid mid-ranger known for its 23MP camera and sleek design. However, by 2026, the official stock software has long been outdated, leading to potential security risks, app incompatibility, and sluggish performance.
