Battery Life Comparison

MIUI

• Stock MIUI: Moderate (bloatware drains)
• Debloated MIUI: Good
• Aggressive battery management: Kills apps sometimes

Real-world: 4-6 hours SOT typical

AOSP

• Without GApps: Exceptional (best possible)
• With Pico GApps: Very good
• With Full GApps: Similar to MIUI

Real-world: 5-8 hours SOT possible

Winner: AOSP (especially without Google)

Camera Quality

MIUI Camera

Strengths:

• Optimized for Xiaomi sensors
• All hardware features work
• Leica partnership (flagship models)
• Video features complete

Weaknesses:

• Processing can be aggressive
• Some modes are gimmicky
• Region-locked features

AOSP + GCam

Strengths:

• Google's processing algorithms
• Better night mode
• More natural colors
• HDR+ enhanced

Weaknesses:

• Aux cameras may not work
• Video features limited
• Need to find right config

My take: GCam on AOSP often produces better photos than MIUI camera. But MIUI has more features.

User Experience

MIUI Experience

Feels like: iOS crossed with Android

Good for people who:

• Like iOS design
• Want features out-of-box
• Use Xiaomi ecosystem (Mi Band, etc.)
• Need dual apps/second space
• Don't mind learning MIUI-specific workflows

AOSP Experience

Feels like: Pure Google/Pixel

Good for people who:

• Prefer stock Android
• Want simplicity
• Hate bloatware
• Value privacy
• Are familiar with Pixel/stock Android

---

Ads and Bloatware

MIUI Bloatware

Pre-installed apps vary by region but often include:

• Mi Browser (has ads)
• Mi Video (has ads)
• GetApps store
• Music app
• Various Mi services
• Partner apps

Can be uninstalled/disabled but annoying out of box.

AOSP

Typically includes:

• Essential apps only
• Calculator, Clock, Calendar
• Files app
• Whatever you install
• Google apps if you flash GApps

Clear winner: AOSP

---

Updates

MIUI Updates

• Security patches: Monthly (flagships), Quarterly (others)
• New MIUI versions: Regular
• Android base updates: Slow (Xiaomi priority is MIUI features)

Example: Flagship might get Android 14 6 months after release

AOSP Updates

• Security patches: Monthly or faster
• Android base: Often faster than OEM
• Features: Depends on ROM

Example: LineageOS often has new Android before MIUI

Winner: AOSP for update speed

---

Stability Comparison

MIUI Stability

• Official releases: Very stable
• Beta: Can be buggy
• Everything works out of box
• Xiaomi-specific hardware 100% functional

AOSP Stability

• Official builds: Stable
• Unofficial: Varies
• May have hardware quirks
• Camera/sensors might need workarounds

Winner: MIUI for zero-effort stability

---

Privacy

MIUI Privacy Concerns

• Telemetry to Xiaomi servers
• Analytics embedded in apps
• "Security" app has privacy implications
• Regional differences (China vs Global)

AOSP Privacy

• Minimal telemetry (LineageOS)

Winner: AOSP (especially without Google)
