Anbernic claims "up to 6 hours" battery life for the R36S. iGC measured the real battery life across 4 different systems at standardized brightness and volume. Here are the actual numbers — not marketing claims.
🔋 Battery Test Summary
| System | Battery Life | Emulator | Assessment |
|---|---|---|---|
| GBA / GBC | 5.2 hours | mGBA | ✅ Excellent — covers any commute |
| SNES / NES | 4.8 hours | Snes9x | ✅ Excellent — full day gaming |
| PS1 | 4.2 hours | PCSX-ReARMed | ✅ Good — covers most sessions |

| Max Brightness (GBA) | 3.9 hours | mGBA | ⚠️ Reduced — use 60% for best life |
| Min Brightness (GBA) | 6.1 hours | mGBA | ✅ Maximum — indoor use |
1. Set brightness to 40–60% indoors — biggest battery saver
2. Lower volume or use headphones at lower volume
3. Use save states and turn off when not playing
4. GBA/SNES games use less battery than PS1/N64
5. Charge with a quality USB-C cable — cheap cables charge slower

|---|---|---|
| USB-C (5V/2A) | ~2.5 hours | ✅ Standard — recommended |
| USB-C (5V/1A) | ~4 hours | ⚠️ Slow — use 2A charger |
