Pure AOSP 17 · battery-focused · black / grey UI · POCO F6 (peridot)
Hobby pure AOSP Android 17 ROM. Priority is battery and a small, dark UI — not skins or feature bloat.
| Android | 17 · AOSP |
| Focus | Battery · smooth daily use |
| UI | Black background · grey accents/dots only |
| Device | POCO F6 / Redmi Turbo 3 (peridot) first |
| Status | WIP — trees & brand public; A17 bring-up ongoing |

Modern Android often spends its budget on the wrong things: cosmetic skins, endless animations, heavy artworks, feature checklists, and placebo “optimizations” that look impressive in screenshots and feel worse in the pocket.
That cost is not free. It steals:
| What gets spent | What you lose |
|---|---|
| GPU / compositor work on flashy UI | Smoothness and frame consistency |
| Always-on visual noise | Fluidity under real multitasking |
| Bright panels, skins, effects | Battery juice you needed by evening |
| Bloated “exclusive” features | Stability, updateability, AOSP clarity |
BestROM rejects that trade.
We believe a daily driver should feel fast because it is light, not because it papered over jank with motion blur and marketing. Battery is not a settings page we remember later — it is the primary design constraint. Every default, every surface, every optional extra has to answer:
- Does this help battery (or at least not hurt it)?
- Does this keep the system smooth and fluid under real use?
- Is it still AOSP-compliant and maintainable — not a one-off skin fork?
If the answer is “it looks cool in a trailer,” it does not ship as a default.
| We skip | Why |
|---|---|
| Heavy cosmetic skins | CPU/GPU and memory tax for brand theater |
| Animation for animation’s sake | Motion should clarify, not perform |
| Artwork walls & bright chrome | AMOLED pays in milliwatts; battery pays in hours |
| Feature bloat & placebo toggles | Complexity without real endurance or fluidity |
| “Everything maxed” defaults | 120 Hz + light UI + effects is the opposite of our product |
| We ship | Why |
|---|---|
| Pure AOSP 17 base | Clean path, fewer surprise layers, real compliance |
| Black + grey only | Brand colors forbidden except greys — Nothing-like quiet |
| Grey dotted marks | B / BESTROM as dots — thrifty on AMOLED |
| Thrifty controls | Charge limit, refresh sense, power-save that cuts cost |
| Daily-driver honesty | Radio, camera, stability over screenshot features |
BestROM = AOSP soul + Nothing-like monochrome.
Same taste as Nothing OS: ultra minimal, empty space, grey dotted letters. Not a clone: pure AOSP 17, pure black canvas, no brand hues — only black and grey.
Black. Grey dots. Ultra minimal. More battery. Still Android — pure AOSP 17.

Hard palette law: brand design may use only black and greys. No violet, cyan, or other hues.
| Law | Meaning |
|---|---|
| Pure black canvas | #000000 backgrounds — always |
| Grey dots only | Logo / wordmark = mid greys #9CA3AF / #D1D5DB on black |
| Ultra minimal | Empty space > decoration (Nothing-like quiet) |
| No brand rainbow | Zero violet/cyan/neon in BestROM chrome |
| No light product skin | Dark-only from Setup → home → Settings → QS |
| Motion stays cheap | Short grey-dot assemble — no color cycles |

m -j$(nproc)Peridot on A17 is a first-of-kind effort. Trees on branch 17 start from working 16.2 sources and need HAL / sepolicy / kernel bring-up.
