TCL Flip 4 5G: In an era dominated by touchscreen smartphones with ever-expanding displays, the flip phone format maintains a dedicated following for its compact design, tactile interface, and focused functionality.
TCL, a company known for delivering value-oriented technology products, has entered this specialized market with the TCL Flip 4 5G.
This device represents a thoughtful modernization of the classic flip phone design, incorporating contemporary connectivity and features while preserving the simplicity that makes this form factor appealing.
This comprehensive analysis explores what makes the TCL Flip 4 5G a noteworthy option for those seeking an alternative to traditional smartphones in 2025.
Design and Build Quality
The TCL Flip 4 5G embraces the iconic clamshell design that defined mobile phones in the early 2000s, updated with modern materials and engineering. When closed, the device measures a pocket-friendly 107.8 × 56.3 × 19.2mm, expanding to approximately 205mm in length when opened. At 145g, it offers reassuring heft without feeling cumbersome.
The exterior features a durable polycarbonate body reinforced with a metal hinge mechanism that has been tested for over 200,000 fold cycles.
The hinge provides satisfying resistance when opening and closing the device, with a definitive snap when fully extended that evokes the tactile satisfaction of traditional flip phones.
Available in three colorways—Midnight Black, Vintage Silver, and Marine Blue—the device offers aesthetic options to suit different preferences.
The Marine Blue variant features a subtle gradient effect that shifts in different lighting conditions.
The exterior of the device houses a 2.8-inch AMOLED display that shows notifications, time, date, weather, and allows for basic interactions without opening the phone. This external display is protected by Gorilla Glass 5, offering substantial resistance to scratches and minor impacts.
Display Technology
When opened, the TCL Flip 4 5G reveals its primary 3.7-inch AMOLED internal display with a resolution of 1080 × 860 pixels.
This panel delivers vibrant colors and deep blacks, with a peak brightness of 800 nits ensuring good visibility in most lighting conditions.
The display supports a standard 60Hz refresh rate, which is more than adequate for the typical use cases of this device. The panel offers excellent viewing angles and color reproduction, making text messages, contact information, and media content clear and legible.
Unlike many contemporary flip phones that attempt to incorporate full-touchscreen interfaces, the TCL Flip 4 5G embraces a hybrid approach.
The main display supports touch input for scrolling and selecting items, but the primary navigation is handled by the physical keypad, creating an intuitive experience that bridges traditional and modern interaction models.
Performance and Hardware
The TCL Flip 4 5G is powered by the Qualcomm Snapdragon 4 Gen 2 processor, a mid-range chipset that balances performance and power efficiency.
This octa-core processor, featuring two Cortex-A78 cores at 2.0GHz and six Cortex-A55 cores at 1.8GHz, delivers sufficient performance for the device’s intended use cases.
The phone includes 4GB of RAM and 64GB of internal storage, with support for microSD expansion up to 512GB. This hardware configuration ensures smooth operation of the lightweight KaiOS 4.0 operating system and provides ample space for contacts, messages, photos, and applications.
Battery performance is exceptional, with the 2500mAh capacity easily delivering 2-3 days of typical usage, significantly outperforming most modern smartphones. The device supports 18W fast charging via USB-C, reaching a full charge in approximately 90 minutes.
Camera System
The TCL Flip 4 5G features a straightforward camera setup consisting of:
13MP rear camera with LED flash (f/2.0 aperture)
8MP front-facing camera (f/2.2 aperture)
While modest by smartphone standards, the camera system delivers surprisingly capable results for everyday photography.
The rear camera captures detailed images in good lighting conditions, with the LED flash ensuring usability in dimmer environments.
The front-facing camera is adequately positioned for video calls and occasional selfies. Both cameras support 1080p video recording at 30fps, providing serviceable quality for capturing memorable moments.
The camera application offers simplified controls that are easy to navigate using the physical keypad, including modes for photo, video, portrait, and panorama. Basic editing tools allow for cropping, filters, and adjustments before sharing.
Operating System and Software
The TCL Flip 4 5G runs on KaiOS 4.0, an operating system specifically designed for feature phones with physical keypads.
This lightweight platform provides a focused experience with essential functionality while maintaining compatibility with key modern services.
The interface is navigated primarily through the directional pad and keypad, with touch input available as a supplementary interaction method.
The home screen presents a grid of applications that can be traversed using the directional buttons, with dedicated keys for common functions like camera, messages, and calling.
Despite its simplified nature, KaiOS 4.0 supports several essential applications including:
Google Assistant for voice commands
Google Maps for navigation
YouTube for video consumption
WhatsApp for messaging
Facebook and Twitter for social media
Email client with support for major providers
The KaiOS Store provides access to a curated selection of applications designed specifically for this platform, though the ecosystem is naturally more limited than Android or iOS.
Connectivity and Additional Features
The TCL Flip 4 5G, as the name suggests, supports 5G connectivity, ensuring fast data speeds where available. This future-proofs the device and represents a significant upgrade from previous generations of flip phones. Other connectivity options include:
Wi-Fi 5 (802.11ac)
Bluetooth 5.2
GPS/GLONASS/Galileo
NFC for contactless payments
FM Radio
3.5mm headphone jack
USB Type-C port
The device features a physical numeric keypad with large, backlit buttons that provide excellent tactile feedback. The T9 predictive text input has been modernized, offering surprisingly efficient text entry after a brief adjustment period.
Accessibility features are comprehensive, including text-to-speech, adjustable font sizes, hearing aid compatibility, and dedicated SOS functionality that can automatically contact emergency services and predetermined contacts when triggered.
