A data-driven comparison across battery life, performance, stability, and daily usability in 2026.
Should you run a clean AOSP ROM, a HyperOS-based custom ROM, or stick with your device's stock firmware? After testing 80+ ROMs across all three categories on the Poco X6 Pro 5G, we have a clear, data-backed answer — though it depends on what you actually need.
| Category | AOSP Custom | HyperOS Custom | Stock HyperOS |
|---|---|---|---|
| Performance | Excellent | Good | Good |
| Battery Life | Best | Good | Good |
| Stability | Good | Good | Best |
| Camera Quality | Basic | Excellent | Excellent |
| Customization | Excellent | Good | Limited |
| Bloatware | None | Minimal | Heavy |
| Privacy | Best | Good | Poor |
| Banking Apps | Mostly OK | Full support | Full support |
| Update Frequency | Monthly | Monthly | OTA |
| Gaming FPS | Highest | High | Lower |
AOSP ROMs like Axion OS, Infinity X, crDroid, LineageOS and Evolution X are built on Android Open Source Project code — clean, minimal, and highly tunable. In our testing, AOSP ROMs consistently delivered:
Downsides: Camera processing is usually inferior (no AI enhancements), and some banking apps may require additional setup. Clean flash required when switching.
HyperOS-based custom ROMs like Saan OS, Tenge OS, Flame OS, PirateOS, and Zendroid keep Xiaomi's camera stack and app ecosystem while removing bloatware and adding customization. Best of both worlds for many users.
Stock HyperOS 3 (Global) is actually very good in 2026 — Xiaomi has improved significantly. If you need guaranteed camera quality, banking app support, and OTA updates, stock is a valid choice. But you give up performance, privacy, and customization.
