Phonemax R4 Mini Guide: Specs, 4G Bands & Performance

By Phonemax Editorial Team · Updated August 3, 2026

Most rugged smartphones are built around large screens and heavy batteries. The Phonemax R4 Mini takes a different route: it is a 4-inch Android 14 rugged phone measuring 121 × 59.5 × 15.5 mm and weighing about 150 g. It combines a pocket-friendly body with 4G LTE, NFC, dual-SIM support, expandable storage and an infrared night-vision camera.

Phonemax R4 Mini specifications—and what they mean

Specification	Published detail	What it means
Display	4-inch IPS, 540 × 1080	Easy to carry and use one-handed, but maps, keyboards and long documents have less working space.
Size and weight	121 × 59.5 × 15.5 mm; about 150 g	More pocketable than a typical full-size rugged handset while retaining a protective chassis.
Operating system	Android 14	Provides a modern Android base, although buyers should still check app requirements and the current update policy.
Processor	Unisoc T606	Designed for calling, messaging, navigation and routine apps rather than demanding 3D games or heavy editing.
Memory and storage	4 GB RAM; 64 GB storage; microSD support	Enough for everyday tasks with sensible app management; a memory card can add space for offline maps, photos and files.
Battery	3,000 mAh	Supports the compact dimensions, but real runtime depends heavily on signal strength, screen time, GPS and camera use.
Cameras	Rear camera, infrared night vision and front camera	The infrared mode can reveal nearby subjects in darkness; it is not thermal imaging and does not measure heat.
Connectivity	4G LTE, dual SIM, NFC, Wi-Fi, Bluetooth and GPS	Covers daily communication, contactless functions and navigation, subject to carrier, app and regional compatibility.
Reported benchmark	AnTuTu v10: 269,410, reported by Kimovil	Suggests entry-level everyday performance; results can change with firmware, temperature and background activity.

Specifications are based on the official product listing. The benchmark is a third-party database result and was not reproduced by Phonemax.

4G LTE frequency bands

The R4 Mini is sold in regional network versions. Select the version whose bands match both your carrier and the places where you expect to use the phone.

Version	Published bands	What it means
Europe / Asia 4G FDD	B1, B3, B5, B7, B8, B19, B20, B28A, B28B	Includes a mix of capacity and lower-frequency coverage bands used across many European and Asian networks.
Europe / Asia 4G TDD	B38, B40, B41	Adds compatibility with TDD LTE deployments where supported by the local operator.
Americas 4G FDD	B2, B4, B5, B7, B17, B28A, B28B	Covers several common LTE bands in the Americas, but band overlap alone does not guarantee carrier activation or VoLTE support. Several bands widely used by US carriers—including B12, B13, B66 and B71—are not listed.
3G	B1, B5, B6, B8	Legacy fallback depends on whether the local operator still maintains a 3G network.
2G	B2, B3, B5, B8	May provide basic voice or fallback service in some regions, but many operators have retired or are retiring 2G.

Before buying: confirm the exact LTE bands, VoLTE requirements, IMEI policy and device allowlist with your carrier. In the United States especially, matching one or more bands does not by itself guarantee activation.

Reported benchmark and day-to-day performance

Kimovil reports an AnTuTu v10 score of 269,410 for the 4 GB / 64 GB configuration. That result fits the Unisoc T606’s everyday-use positioning: messaging, email, calls, barcode or field apps, music and turn-by-turn navigation should be the natural workload.

What the number does not prove: one aggregate score cannot guarantee smooth performance in every app. Firmware version, thermal conditions, storage fill level and background processes can all change the result. Phonemax did not independently rerun this test.

A third-party CES observation

Mobil.iDNES.cz

Its CES hands-on coverage highlighted the compact form factor and observed that text on the small display could be difficult to read. This supports the most important practical trade-off already evident from the published four-inch screen specification: portability improves, while typing and dense interfaces may require more zooming and precision.

This is a published event observation, not a controlled battery, display or durability test.

Infrared night vision and NFC

Infrared night vision

The infrared night-vision camera is intended for close-range visibility in very low light. It can help with nearby inspection tasks, dark storage areas or campsite checks. It does not detect temperature and should not be described as a thermal camera.

NFC

NFC can support compatible contactless-payment, access, tag-reading and automation apps. Availability depends on the country, bank, wallet app and security requirements.

Who the R4 Mini is for

One-handed-phone buyers

The 4-inch display and 150 g body prioritize portability.

Field and outdoor users

The rugged format, GPS, NFC and infrared camera support practical mobile tasks.

Minimalist users

The smaller display can discourage prolonged browsing while retaining core Android apps.

Secondary-phone buyers

Dual-SIM support and compact dimensions make it easier to carry as a backup device.

It is a less natural fit if your work depends on large spreadsheets, long typing sessions, high-end mobile gaming or all-day maximum-brightness navigation. The small screen and 3,000 mAh battery are design trade-offs, not hidden details.

Price and buying checklist

As checked on August 3, 2026, the official store lists the R4 Mini at US$138, with a compare-at price of US$189. Prices, taxes, shipping and promotions can change by region and date.

Select the correct Europe / Asia or Americas network version.
Confirm carrier bands, VoLTE and activation eligibility before ordering.
Decide whether a 4-inch screen suits your typing and accessibility needs.
Treat the reported benchmark as a useful reference, not an independent lab result.
Check the live product page for current price, stock and configuration.

Frequently asked questions

Is the Phonemax R4 Mini practical for daily use?

It can be practical for calls, messaging, navigation and routine Android apps. The main question is whether the four-inch display is comfortable for your reading and typing habits.

Which network version should I buy?

Choose the Europe / Asia or Americas version by comparing its published LTE bands with your carrier’s bands. Also confirm VoLTE, IMEI and device-allowlist requirements directly with the operator.

Will it work with a US carrier?

The Americas version publishes several US-used LTE bands, but it does not list some bands widely used by US carriers, including B12, B13, B66 and B71. Compatibility is not guaranteed by band overlap alone. Ask the carrier to confirm activation, VoLTE and IMEI eligibility before purchase.

How fast is the R4 Mini?

Kimovil reports an AnTuTu v10 score of 269,410. That suggests suitability for communication, navigation and everyday apps rather than demanding gaming or heavy multitasking. Phonemax did not independently reproduce the score.

Is the four-inch screen too small?

It depends on the task. The screen supports pocketability and one-handed use, but long typing, dense webpages and complex app interfaces may require more scrolling or zooming.

Is infrared night vision the same as thermal imaging?

No. Infrared night vision illuminates nearby subjects in darkness; thermal imaging detects heat patterns. The R4 Mini has night vision, not thermal imaging.

Has this article independently tested battery life, waterproofing or drops?

No. This page is published by Phonemax and is not a hands-on lab test. Battery runtime, display brightness, waterproofing and drop resistance were not independently tested under controlled conditions for this article.
