The Redmi Note 15 Pro Max 5G has quickly become one of India’s most popular mid-range smartphones. With its 200 MP main camera, 120 W fast charging, and MIUI 15 software, it offers excellent value — but many users don’t realise how much more they can extract with the right settings.
In this guide, we’ll explore how to tune the camera for professional-quality results, extend battery life, and optimise system performance on your Redmi Note 15 Pro Max 5G as of November 2025.

Camera Optimisation Tips for Stunning Photos
1. Switch to 200 MP Mode for Maximum Detail
By default, the phone uses pixel-binning for balanced photos, but if you want ultra-sharp results, open the camera app → select 200 MP mode. This captures massive detail in daylight or when cropping.
Verdict: Perfect for landscape, architecture, and product photography in bright Indian conditions.
2. Use Pro Mode with Manual ISO Control
For night shots, open Pro Mode and set ISO around 800–1600 with a 1/10s shutter. This reduces grain and gives more control over lighting.
Verdict: Ideal for advanced users who want DSLR-like control without carrying a camera.
3. Turn On AI Scene Enhancement
Navigate to Camera Settings → AI Mode → Enable Scene Enhancement. This automatically adjusts saturation, sharpness, and tone mapping based on Indian daylight and skin tones.
Verdict: Boosts colour vibrancy, especially useful for festivals and food shots.
4. Enable HDR Always-On
Under camera settings, toggle HDR → Always On. This ensures balanced highlights and shadows in both indoor and outdoor shots.
Verdict: Prevents overexposed skies and dark faces — a must for Indian daylight conditions.
5. Use 2× In-Sensor Zoom for Portraits
The 200 MP sensor supports lossless 2× zoom. Instead of using digital zoom, tap 2× in the camera app — it crops directly from the main sensor, maintaining quality.
Verdict: Results in DSLR-like portrait clarity without needing a telephoto lens.
6. Turn Off Beauty Mode for Natural Photos
For professional-looking shots, go to Portrait → Filters → None, and disable Beauty Mode. This preserves realistic texture and avoids overly smooth faces.
Verdict: Keeps portraits authentic and print-ready.
7. Shoot Videos in 4K 30 FPS for Balance
While 60 FPS offers smoother footage, it drains more battery. Shooting at 4K 30 FPS delivers cinematic quality without overheating.
Verdict: The best balance between quality and stability for vloggers and content creators.
8. Adjust Focus Peaking in Pro Video Mode
Enable Focus Peaking for manual focus control when recording videos. It highlights focused areas in red, ensuring sharp subject tracking.
Verdict: Essential for travel or street videography.
Battery & Power Management Tips
The Redmi Note 15 Pro Max 5G’s 5,160 mAh battery and 120 W HyperCharge support make it a powerhouse, but with smart tweaks, you can stretch battery life by 20–25%.
1. Use Optimised Charging
In Settings → Battery → Charging Optimisation, enable “Smart Charge.” It slows charging at 80% overnight, preventing overheating and battery wear.
Verdict: Extends long-term battery health.
2. Set Screen Refresh Rate to 90 Hz
Although the display supports 120 Hz, switching to 90 Hz under Display Settings gives smoother visuals while saving power.
Verdict: Great compromise for battery-conscious users without losing smoothness.
3. Use Ultra Battery Saver Mode
When travelling or low on charge, activate Ultra Battery Saver. It restricts background apps, vibration, and data sync — extending standby time dramatically.
Verdict: Useful during long trips or outdoor events where charging options are limited.
4. Manage Background Apps
Go to Settings → Battery → App Battery Saver, and set less-used apps like Facebook or Snapchat to “Restricted” mode.
Verdict: Reduces unnecessary battery drain and keeps system performance consistent.
5. Adjust Screen Timeout and Brightness
Set screen timeout to 30 seconds and use Auto Brightness for adaptive control.
Verdict: Saves up to 10% battery daily in mixed-use scenarios.
6. Disable 5G When Not Needed
If you’re not using high-speed downloads, switch to 4G Preferred in network settings.
Verdict: Extends battery life by 1–1.5 hours per charge cycle, especially in areas with unstable 5G coverage.
7. Limit Location & Bluetooth Access
Under Privacy → Permissions, set location access to “While Using App” and disable Bluetooth scanning when unused.
Verdict: Cuts idle drain by around 5–7%.
8. Enable Dark Mode and Battery Saver Together
Using Dark Mode along with System Battery Saver reduces screen power draw on AMOLED panels.
Verdict: Enhances battery endurance and also reduces eye strain during night use.
9. Keep MIUI Updated
Each MIUI 15 update improves thermal management and optimises background resource usage.
Verdict: Staying updated ensures consistent battery and camera stability over time.
Performance & Storage Optimisation
1. Use Memory Extension
In Settings → Additional Settings → Memory Extension, enable +4 GB Virtual RAM. This feature allocates unused storage for multitasking and gaming.
Verdict: Reduces lag during app switching or gaming sessions.
2. Clean Cache Periodically
Go to Settings → Storage → Clear Cache every few weeks. This prevents slowdowns due to temporary system files.
Verdict: Keeps phone running like new, even after months of use.
3. Turn Off Auto App Updates on Mobile Data
Set Play Store to Wi-Fi only updates. This saves both data and power.
Verdict: Prevents background syncing that drains battery.
4. Use Game Turbo Mode
Under MIUI Security App → Game Turbo, add your favourite games. This automatically optimises CPU, GPU, and RAM for sustained gaming.
Verdict: Boosts gaming stability and frame rates while managing heat better.
Best Charging Practices for Long-Term Battery Health
-
Avoid charging beyond 90% daily.
-
Use the original 120 W charger for safety and efficiency.
-
Keep the phone cool during charging — avoid direct sunlight.
-
Disconnect once charged; fast chargers maintain a current that can heat up batteries if left plugged in.
Verdict: Proper charging habits can help maintain over 85% battery capacity even after two years.
Final Verdict
The Redmi Note 15 Pro Max 5G already offers exceptional battery and camera performance, but with these simple settings, users in India can elevate their daily experience. Whether it’s sharper portraits, extended gaming sessions, or consistent power backup, fine-tuning these controls ensures long-term reliability.
Overall Verdict: With the right MIUI 15 optimisations, the Redmi Note 15 Pro Max 5G transforms from a great smartphone into a long-lasting, creator-friendly powerhouse.
