1. Fixing Screen Flicker & Eye Strain

The 6000 nits display is bright, but low brightness uses PWM which can flicker.

Steps 1-3: Visual Comfort

2160Hz Dimming: Go to Settings > Display > Eye Comfort. Ensure "Low Brightness Flicker-Free Eye Care" is enabled (if available in Developer Options).
DC Dimming: If available, turn ON "DC Dimming" in Realme Labs. It stabilizes the current to reduce flicker.
Refresh Rate: Set Refresh Rate to "Standard" (60Hz) or "High" (120Hz). Avoid "Auto Select" if you notice stuttering while scrolling.

2. Optimizing Battery (Realme UI 5.0)

GT Mode boosts performance but kills battery. Use it wisely.

Steps 4-6: Power Tuning

GT Mode: Only enable "GT Mode" during heavy gaming. For daily use (Instagram/YouTube), keep it OFF to save 20% battery.
Smart 5G: Go to Mobile Network > Advanced Settings. Turn ON "Smart 5G". It switches to 4G when the phone is idle or screen is off.
App Freeze: Go to Battery > More Settings > App Quick Freeze. Freeze shopping apps and games you don't use often.

3. Fixing Camera Shutter Lag

The Sony LYT-808 sensor is top-tier, but software needs speed.

Steps 7-9: Instant Capture

Action Mode: In Camera settings, look for "Action Mode" or "Motion Capture". Enable it to prioritize shutter speed for moving subjects.
HEIF Format: Enable "HEIF" in Camera settings. It saves images faster to the UFS 4.0 storage.
Clear Cache: Long press Camera Icon > App Info > Storage > Clear Cache. Do this weekly to prevent the viewfinder from lagging.

💡

GT Tip: Use the "Geek Power Tuning" in Game Assistant to manually adjust CPU/GPU clock speeds for specific games.

4. Removing UI Stutter

Realme UI animations can sometimes glitch.

Steps 10-12: Smoothness

RAM Expansion: Go to About Device > RAM. Turn OFF "RAM Expansion". The physical LPDDR5X RAM is fast enough; virtual RAM causes lag.
Animation Scale: Go to Developer Options. Set all animation scales to 0.5x. This matches the fast feel of the GT series.
High Performance: In Battery settings, ensure "High Performance Mode" is OFF for daily tasks. It causes thermal throttling which leads to lag.

Warning: Use the 120W SuperVOOC charger provided. PD chargers will charge slowly (18W-30W max) and may heat up the device.

Additional Maintenance (Steps 13-15)

Step 13 (Phone Manager): Run the "Phone Manager" optimization daily to clear junk files.
Step 14 (Restart): Restart your GT 6 every 3 days. It clears the RAM buffer and refreshes the modem.
Step 15 (Update): Check for Realme UI updates. They release specific "Gaming Performance" patches regularly.
