The Redmi 15C has quietly become one of the most talked-about devices in the budget smartphone category. While most people know about its impressive 6.9-inch display and massive 6,000 mAh battery, there's so much more beneath the surface that makes this device truly special.
If you're considering this as one of the best phones under 20k in Kenya or already own one, you're in for a treat. The Redmi 15C packs features that you'd typically find in much more expensive devices, thanks to Xiaomi's clever software engineering and the new HyperOS 2 operating system.
Let's dive into ten incredible features that most users never discover, but could completely change how you use your device.
Is Redmi 15C the Best Inexpensive Cell Phone?
Before we explore these hidden gems, it's worth clearing up some confusion that's been floating around online. Early rumors suggested the Redmi 15C would come with a MediaTek Helio G35 processor and a 13MP camera. However, the final device that hit the market is significantly more powerful.
The actual Redmi 15C features a MediaTek Helio G81-Ultra chipset, a 50MP AI dual-camera system, and Android 15 with Xiaomi HyperOS 2. This upgrade makes a huge difference in real-world performance and explains why the Redmi prices in Kenya position this device as such excellent value for money.
Memory Extension—Turn Your Phone Into a Multitasking Beast
One of the most impressive features hidden in your Redmi 15C is Memory Extension. Did you know that you can actually expand the memory of your Redmi 15C up to 16GB?
Here's how it works: the system intelligently uses a portion of your internal storage as additional RAM. This means you can keep more apps running in the background without experiencing slowdowns or having apps reload when you switch between them.
To activate this feature, head to Settings, scroll down to Additional settings, and look for Memory extension. You can choose to add 1GB, 2GB, or even 4GB of virtual RAM. Your phone will need a quick restart, but the performance boost is immediately noticeable.
This feature is particularly valuable if you've got the 4GB RAM variant, as it essentially transforms your device's multitasking capabilities without any hardware upgrade.
Your Phone Can Charge Other Devices
Here's something that might surprise you – your Redmi 15C can actually work as a portable power bank. The device supports wired reverse charging at up to 10W, meaning you can use its massive 6,000 mAh battery to charge other gadgets.
This feature has caused some confusion online, with some users claiming it doesn't exist. The trick is that you need an OTG (On-The-Go) adapter or compatible cable, and you must respond to the software prompt that appears when you connect another device.
Imagine being able to charge your wireless earbuds, smartwatch, or even help a friend with a dead phone battery. It's incredibly handy during emergencies or when you're away from power outlets for extended periods.
Privacy Features That Rival Premium Phones
Your Redmi 15C comes with built-in privacy features that are surprisingly sophisticated. You can hide both apps and photos without needing any third-party applications.
To hide apps, open the Security app, scroll down to "Hidden apps," and toggle the switch for any app you want to keep private. The clever part is how you access these hidden apps – simply do a two-finger outward swipe gesture on your home screen.
For photos and videos, the process is equally elegant. Select the files you want to hide in the Gallery app, tap the three dots, and choose "Add to private album." To access your private album later, swipe down on the main Photos tab until a lock icon appears.
These features are seamlessly integrated into the operating system, making them both secure and easy to use.
Gesture Shortcuts That Save Time
Beyond the standard button combinations, your Redmi 15C offers several gesture-based shortcuts that can significantly speed up your daily interactions with the device.
The three-finger screenshot is probably the most useful. Enable it by going to Settings > Additional settings > Gesture shortcuts > Take a screenshot. Once activated, a quick three-finger swipe down captures whatever's on your screen instantly.
But that's not all. You can double-press the volume down button to quickly launch the camera, perfect for capturing spontaneous moments. Double-pressing the power button instantly turns on the flashlight, which is incredibly handy in dark situations.
These shortcuts might seem small, but they add up to create a much more fluid user experience throughout the day.
Seamless Device Integration With HyperOS
One of the most underrated aspects of the Redmi 15C is how it connects with other Xiaomi devices. The new HyperOS 2 brings interconnectivity features that create a unified ecosystem experience.
If you have other compatible Xiaomi devices like tablets, you can enjoy features like Call Sync, which lets you take phone calls on your tablet. The Shared Clipboard feature is equally impressive – copy text or images on your phone and paste them directly on your tablet.
All you need is to sign into the same Xiaomi account on all devices and have Bluetooth and Wi-Fi activated. It transforms your smartphone from a standalone device into part of a collaborative ecosystem.
Wet Touch Technology That Actually Works
Here's a feature that's rarely mentioned in reviews but makes a real difference in daily use. The Redmi 15C features Wet Touch Technology 2.0, which keeps the screen responsive even when your hands are wet, damp, or oily.
This isn't something you need to enable – it's built into the hardware. Combined with the phone's IP64 rating for dust and splash resistance, it means you can use your device confidently while cooking, in light rain, or right after washing your hands.
It's one of those thoughtful design choices that you don't notice until you need it, but then you wonder how you lived without it.
One-Handed Mode for the Large Display
The 6.9-inch display on the Redmi 15C is fantastic for media consumption, but it can be challenging to operate with one hand. Xiaomi has addressed this with a smart software solution called One-Handed Mode.
This feature scales down the entire interface to a smaller, more manageable size and pulls it to the bottom corner of the screen for easy thumb access. Enable it through Settings > Additional settings > One-handed mode.
Once activated, a simple swipe down from the home button triggers the scaled-down view. It's a perfect example of how software can solve hardware challenges elegantly.
200% Volume Boost for Better Audio
The Redmi 15C has a mono speaker, which is typical for its price range. However, the software includes a clever workaround – a 200% volume boost feature that can make the speaker significantly louder.
This feature activates when you push the volume past its standard maximum. It's particularly useful in noisy environments or when you need to hear notifications and calls clearly.
While it won't turn your phone into a premium audio device, it ensures you get satisfactory sound performance despite the hardware limitations.
Understanding the "Flashing Light" Mystery
Many new users get concerned when they see a small, flashing white light near the top of the screen during phone calls. This isn't a dead pixel or hardware defect – it's actually the proximity sensor doing its job.
This sensor detects when you bring the phone close to your face and automatically turns off the screen to prevent accidental touches and save battery. The flashing light is the infrared LED that makes this detection possible.
Understanding this simple fact can save you unnecessary worry and help you appreciate this thoughtful feature that enhances the calling experience.
Developer Options for Advanced Customization
Your Redmi 15C isn't locked down like some budget devices. It includes hidden Developer Options that unlock advanced system settings for those who want to tinker with their device.
To access this menu, go to Settings > About phone and repeatedly tap on "OS version" until you see "You are now a developer." The Developer Options will then appear under Additional settings.
From here, you can adjust animation speeds, enable USB debugging, and access various other advanced features. It shows that despite being positioned as one of the best phones under 20k in Kenya, the Redmi 15C doesn't compromise on customization options.
Making the Most of Your Investment
The Redmi 15C proves that you don't need to spend a fortune to get premium features. These ten hidden capabilities transform what might seem like a basic budget smartphone into a versatile, powerful device that can adapt to your specific needs.
Whether you're drawn to the enhanced multitasking capabilities, the practical reverse charging feature, or the seamless ecosystem integration, each of these features adds real value to your daily smartphone experience.
Understanding and utilizing these features is what separates users who get the most from their devices from those who barely scratch the surface. With competitive Redmi prices in Kenya making this device accessible to many users, knowing about these hidden capabilities ensures you're maximizing your investment.
