| Issue | Stock | Custom | |-------|-------|--------| | Streaming (Tidal/Qobuz) | Works fine | Works, but you may lose DRM if mod isn’t updated | | Bluetooth codecs | LDAC/AAC | Same – no LDAC tweaks possible | | USB DAC mode | Yes | Yes, but some mods break it temporarily | | OTA updates | Yes | No – you must manually flash to revert |
Biggest real-world problem: Some custom builds disable Sony’s proprietary noise-cancelling on the A100 series (the NC included with certain region’s bundled IER-NW500N earbuds). If you use those, avoid the mod.
Also, you lose Google Play in many “hot” builds – so no Spotify unless you side-load the APK (which then re-introduces battery drain). sony nwa105 custom firmware hot
Users are reporting 10-14 hours of continuous FLAC playback. How? The CFW kills Google Play Services when you aren’t using them and underclocks the CPU during screen-off playback. You no longer need to charge your Walkman twice during a work shift.
Based on download counts and forum activity (July 2024 data), here is the ranking: | Issue | Stock | Custom | |-------|-------|--------|
| Firmware Name | Best For | Battery Life | "Hot" Factor | | :--- | :--- | :--- | :--- | | MrWalkman "FEv2" | Sound quality purists | Medium (12h) | Extreme (Uncapped voltage) | | Kuro Mod | Japanese UI & Bass boost | High (15h) | High | | Wampy Nutshell | Battery kings | Very High (18h) | Medium (Volume cap removed but no EQ) | | CronicCorp Xtreme | Power users/Overclock | Low (9h) | Nuclear (Runs physically hot, risky) |
Verdict: The general consensus is that MrWalkman’s FEv2 is the "hottest" because it balances safety with the most aggressive audio unlocks. Users are reporting 10-14 hours of continuous FLAC
Let’s face it—the stock A105 gets maybe 8-10 hours if you’re lucky. CFW drops the bloat. By debloating Google Play Services and background processes, custom builds can push battery life to 15-18 hours of continuous FLAC playback. That is the hottest feature for commuters and travelers.
The stock operating system is stripped of many standard Android background services (Google Play Services, location tracking, etc.) to create a pure audio environment.
