💡 Battery Tips: How to Maximize R36S Battery Life
✅ Tip 1 — Reduce brightness: Dropping from 100% to 50% brightness adds ~1 hour of battery life. The IPS screen is bright enough at 50% for indoor play. iGC recommended setting: 60–70% brightness.
✅ Tip 2 — Play lighter systems: NES and SNES games use less CPU power than N64 and PS1. If battery life is critical, stick to NES/SNES/GBA games for maximum playtime (5.5 hours).
✅ Tip 3 — Use save states: Save your game frequently using the R36S save state feature. This lets you stop playing immediately when battery is low without losing progress.
⚠️ Tip 4 — Avoid full discharge: Don’t let the R36S battery drain to 0% regularly. Charge when the battery indicator shows 20–30% remaining. This extends overall battery lifespan.
