The Redmi Note 12 Pro 5G remains one of the most popular mid-range smartphones in India, offering a perfect balance between performance, design, and camera quality. But what truly makes this phone shine is how much more you can extract from it with a few smart adjustments. Whether you want smoother gaming, faster app launches, or better battery endurance, optimizing your phone can deliver a noticeably improved experience.
In this detailed guide, we share 17 practical tips and tricks every Redmi Note 12 Pro 5G owner should know to maximize performance, battery life, and photography results — updated for November 2025 and MIUI 15.
Enhance Performance and Speed
Enable Performance Mode
Go to Settings → Battery → Battery Saver → Performance Mode and toggle it on. This allows the Dimensity 1080 processor to use its full potential, giving smoother gaming and faster multitasking.
Use Memory Extension
MIUI 15 supports virtual RAM expansion. Navigate to Settings → About Phone → Memory Extension and allocate up to 8GB of virtual RAM. This improves multitasking and keeps more apps open in the background.
Clear Cache Regularly
Over time, system cache can slow down the device. Open Settings → Storage → Cleaner and tap on Deep Clean to remove unnecessary files. This instantly frees up space and improves speed.
Disable Unused System Apps
MIUI comes with preinstalled apps you might not use. Long-press on the app icon → select App Info → Disable. For system apps, open Settings → Apps → Manage Apps → Show All Apps and disable what’s not needed.
Turn Off Animations for Faster Navigation
In Developer Options, set Window Animation Scale, Transition Animation Scale, and Animator Duration Scale to 0.5x or off completely. This makes the system feel instantly more responsive.
Improve Battery Life and Endurance
Use Battery Saver Smart Mode
Go to Settings → Battery → Battery Saver and enable Smart Battery Saver. MIUI 15 intelligently limits background activity and sync frequency to save power when the phone is idle.
Enable Sleep Standby Optimization
Under Settings → Battery → Advanced Settings, toggle on Sleep Standby Optimization. It minimizes battery drain overnight without affecting important notifications.
Manage Background Apps
Visit Settings → Apps → App Battery Saver, and set less-used apps to “Restrict Background Activity.” Apps like Maps or banking tools can be set to “No Restriction” to ensure they work as intended.
Reduce Refresh Rate When Idle
Go to Settings → Display → Refresh Rate, and select Auto. This dynamically switches between 60Hz and 120Hz depending on usage, improving battery longevity.
Optimize Charging Habits
Enable Optimized Charging under Settings → Battery → Battery Health. It pauses charging at 80% when plugged in overnight and resumes before your usual wake-up time.
Boost Camera Quality
Turn on AI Scene Enhancement
In the Camera app → Settings → AI Mode, enable AI Scene Enhancement. This adjusts colors, exposure, and lighting automatically to match the scene you’re shooting.
Use 50MP Mode for Maximum Detail
Switch to Pro Mode → 50MP Lens Option to capture sharper, more detailed photos. Ideal for landscapes and daylight photography.
Improve Low-Light Shots with Night Mode 2.0
For clearer low-light photos, use Night Mode 2.0 from the Camera app. The Dimensity 1080 chip optimizes exposure and noise control, giving better night performance.
Adjust HDR and Filters
HDR can make a big difference in dynamic range. Keep HDR set to Auto, and use Natural Filter for the most balanced tones.
Enable Grid Lines for Better Composition
Open Camera Settings → Composition → Grid Lines, and select 3×3 Grid. This helps align subjects using the rule of thirds for more professional-looking photos.
Use the Pro Mode for Manual Control
For advanced users, Pro Mode allows manual ISO, shutter speed, and white balance adjustment. You can fine-tune every shot like a DSLR.
General MIUI 15 Tips for Smoothness
Keep System Updated
Go to Settings → About Phone → MIUI Version, and ensure you’re on the latest MIUI 15 build. Each update optimizes security and performance.
Turn Off Unused Connectivity Features
Disable Bluetooth, Wi-Fi, and GPS when not in use. Quick toggles in the Control Center make this convenient and help extend battery life.
Use Lite Mode (Optional)
For a minimal, distraction-free experience, go to Settings → Home Screen → Lite Mode. It simplifies the interface and improves performance for casual users.
