Ulefone Armor 15 smartphone review - Rugged outdoor phone with headphones

Complete with secure earbud storage. The Ulefone Armor 15 is drop and water resistant and even comes with its own completely wireless in-ear headphones. The manufacturer thus pushes both dimensions and weight to the extreme, but launches a comprehensive overall package - at a still affordable price.

Case and features - Solid smartphone with metal and rubber

The Ulefone Armor 15 is a so-called rugged smartphone, which means that it is supposed to withstand harsh environmental conditions without damage and is therefore, as usual for such devices, not very compact. In addition, two completely wireless earphones (TWS headphones) can be stored and charged inside the smartphone, which pushes the weight and dimensions even higher - the smartphone weighs 346 grams (~0.76 lb) and is 20 millimeters (~0.8 in) thick at its thickest point.

The display edges are particularly wide on the top and bottom, which is why the smartphone is significantly larger than, for example, the Samsung Galaxy S21, despite the still compact display of 5.45 inches. The casing itself is torsion-resistant and reinforced with rubber edges at the top and bottom. All inputs and outputs are protected by rubber covers. The smartphone lacks Widevine certification, and the L3 rating only allows playing back corresponding material with reduced resolution.

In particular, the rubber corners were damaged...

... and the metal housing. This damage was only visual.

Resilience - The Ulefone Armor 15 keeps its promises

The smartphone is certified according to IP68, IP68K and MIL-STD-810, which means that the smartphone is supposed to be protected against drops from up to 1.5 meters (~4.9 ft) and can be submerged for up to 30 minutes at a depth of 1.5 meters (~4.9 ft). In addition, the smartphone should not be affected by negative pressure, increased humidity, contact with an acidic atmosphere and solar radiation.

The model could also prove the advertised properties in the test. The Armor 15 was dropped from a height of 150 centimeters (~4.9 ft) onto a pavement slab a total of seven times, without installing the included thick protective foil beforehand. Damage was mainly to the reinforced rubber corners. An intentional drop onto the edge of the slab actually scratched a piece of the metal casing significantly, but it remained with cosmetic damage to the case - and a minimal scratch in the display. Even after the drop test, the water resistance to jets of water and immersion remained.

Communication, software and operation - Pure Android, extensive LTE coverage

The quick access key can be assigned quite flexibly
The quick access key can be assigned quite flexibly

Positive: Ulefone uses version 12 of Android without bloatware in the Armor 15. Additional software, for example for outdoor activities, is not installed.

The connection to a 5G mobile network is not possible, but LTE is available. Numerous frequency bands are supported, including the bands that are relevant in Germany - the Ulefone Armor 15 also supports band 20, which is not always supported by cheap imported smartphones. Operation with two SIM cards is possible, and thanks to three card slots, memory expansion via microSD card and dual-SIM are also possible at the same time. However, the microSD card reader only manages below-average data transfer rates and also does not support the exFAT standard. NFC and thus wireless payment is possible. The FM radio can - and must due to the lack of a jack - be used without a connected cable headset, which can be useful in view of the TWS headphones, for example when hiking.

The touchscreen has a glove mode, which allowed the user to operate it even with thick wool gloves in the test. Ulefone has also installed a dedicated camera button on the right side of the casing, and a configurable quick access key is found on the left. This can be assigned with some useful functions, such as the flashlight, but also allows opening apps. Different actions can be defined for a single, a double click and a longer press. The fingerprint sensor in the power button worked reliably in the test, and unlocking with the face is also easy to use in sufficient brightness.

Cameras - Overwhelmed in low light

The quality of the selfie camera is acceptable for video calling
The quality of the selfie camera is acceptable for video calling

The Ulefone Armor 15 has two cameras on the back - the Sony IMX363 sensor offers a resolution of 12 megapixels, plus an S5K3M3 sensor from Samsung with ultra-wide-angle optics. An infrared or night vision camera like in the AGM Glory G1S is not part of the equipment.

The main camera offers a usable quality, at least under optimal conditions, but the sharpness of higher-quality smartphones, such as the Honor Magic4 Pro, is not reached. Overall, the main camera lacks details, and the sensor cannot adequately capture scenes with a large contrast range in particular. The low contrast range and the lack of details also affect the ultra-wide-angle lens. The overall recording quality deteriorates significantly in low brightness.

Video recording is also possible in Full HD resolution with 30 frames per second, although the video recordings also lack details and the autofocus does not work fast enough during fast movements.

The rugged smartphone is equipped with a 16-megapixel front-facing camera. The image quality is more than sufficient for video calls, but the camera's sharpness is not particularly high either. Due to the low brightness of the display, the display flash is not always useful.

Display - Too dark, too small, too low resolution

Subpixel structure
Subpixel structure

The 5.45-inch display offers a resolution of 1,440 x 720 pixels, which is no longer standard in 2022. However, since the screen diagonal is still relatively small, the extent of the subjectively experienced blurriness is still limited. The color reproduction and brightness distribution are acceptable - this is only partly true for the brightness itself.

Although the Ulefone Armor 15 can beat the competing AGM Glory G1S in terms of brightness, 407 cd/m² results in reflections in the manufacturer's intended outdoor use. The minimum brightness is exceptionally high, which results in a lot of eye strain when used at night. The screen's slight bluish cast, which can be measured, is not annoying in use. In the test, there were indications of the use of temporal dithering.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
17.89 ms ... rise ↗ and fall ↘ combined↗ 5.075 ms rise
↘ 12.81 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.4 (minimum) to 240 (maximum) ms. » 29 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (22.7 ms).
       Response Time 50% Grey to 80% Grey
35.41 ms ... rise ↗ and fall ↘ combined↗ 16.45 ms rise
↘ 18.96 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.25 (minimum) to 636 (maximum) ms. » 38 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (35.8 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 5221 Hz

The display backlight flickers at 5221 Hz (Likely utilizing PWM) .

The frequency of 5221 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 19454 (minimum: 5 - maximum: 3846000) Hz was measured.

Performance, emissions and battery life - Long runtime and weak performance

The Helio G35 is a low-priced SoC, which has eight Cortex A53 cores. These clock with up to 2.3 GHz. The working memory of six gigabytes is appropriate for the price range. The performance of the Helio G35 is unremarkable, leaving the Ulefone Armor 15 slow compared with other tested - but also more expensive - rugged smartphones like the AGM Glory G1S.

The weak performance that is evident in the benchmarks is also seen in actual use. Even simple apps do not start without lags. In general, the operating speed is still acceptable, but the refresh rate of only 60 Hz is not conducive to a smooth experience. The Ulefone Armor 15 does not get particularly warm.

The speakers offer a good reproduction quality. The speakers' high, achievable volume might be relevant for outdoor use. The somewhat low-bass reproduction also benefits from the presence of two speakers, which are found above and below the display. Even at higher volumes there are no noticeable distortions.

As expected, the strong 6,000 mAh battery offers a high battery life and reaches a whole 1,059 minutes of runtime in the Wi-Fi test - and thus trumps both the AGM Glory G1S as well as the Samsung Galaxy XCover 6 Pro. Charging is possible with 18 watts, and a charger with a maximum charging power of 15 watts is included.

Headphones - A nice addition

The included headphones fit into the smartphone's casing and are also charged there. The Earbuds are protected from environmental influences by rubber seals, which also provided sufficient protection from water in the test. The headphones are equipped with touch surfaces for operation, whereby playback can be paused and continued, and the next or previous track can also be selected.

In terms of sound quality, the headphones are relatively well positioned and offer a relatively clear sound image even at high volumes. However, the headphones are clearly inferior to Samsung's Galaxy Buds2 Pro, at least in terms of frequency measurement, but the playback quality is quite suitable in practice. The compact headphones are charged in the smartphone. The disadvantage is that the headphones do not have a microphone, which makes them unsuitable as hands-free devices. This would be particularly useful for outdoor use.

Verdict - Durable and slow smartphone with a twist

In test: Ulefone Armor 15. Test device provided by Ulefone.
In test: Ulefone Armor 15. Test device provided by Ulefone.

With the Armor 15, Ulefone offers a smartphone that basically lives up to the manufacturer's self-imposed goals. The integration of the TWS headphones is basically successful, and they even offer a quite high playback quality.

Weak points are the rather dark and low-resolution display and the low performance of the installed SoC.

The performance also affects daily use. The casing, on the other hand, is completely convincing. It is extremely robust and can actually withstand heavy loads. Even after dropping it the water resistance is still good, and the build quality of the model is basically impeccable.

The Ulefone Armor 15 is a smartphone for outdoor professionals and music fans - and only one pocket.

However, Ulefone definitely launches a smartphone for a very pointed target group on the market with the Armor 15, whereby the advertised price of just under 260 Euros (~$251) can definitely put the smartphone's weaknesses into perspective. The bulky and heavy device might be annoying in daily use. Customers looking for a more powerful device will have to pay much more for the Glory G1S from AGM, for example. An alternative from a larger manufacturer would be the Samsung Galaxy XCover 6 Pro, which is also available for a much higher price.

Price and availability

The Ulefone Armor 15 Pro is available directly from the manufacturer, or at Amazon. The model is offered in three color variants.
