Mintt is a new Australian smartphone brand – you may have
seen it recently on Channel 9’s ‘The Block’. The Mintt UltraMintt X3 is its second
most expensive offering – if you call $265 expensive.
We set out to analyse the Mintt UltraMintt X3 and why it offers so much for a paltry $265. It has a reasonable processor, battery, two-year swap warranty, Android 9 (10 coming) and more. Is there a catch?
Mintt has a range of lower-cost phones from $179 that we will review when we can. We have completed the $399 Ultramintt Y3 here, and it punches well above its weight with a triple camera, Qi charging and so much more.
Q: How can Mintt make such low cost, well-featured phones? A: Read the Mintt Ultramintt Y3 review for that answer.
The Mintt UltraMintt X3 is basically the same as Blu G9 (a US company that requires robust FCC certification for each handset). That makes me a lot more confident that this is a tried and tested ODM model.
Mintt is an Australian company (partnering with Mintt Global that operates mainly in PNG and South-East Asia). All Mintt Australia smartphones have RCM (C-tick) certification. They are fully compliant with all Australian Communications and Media Authority (ACMA) requirements for use in Australia.
This means it has the Australian firmware and LTE bands to work
on all Australian Telco carrier networks and can make an 000-emergency call
(not 911) without a SIM.
How we rate smartphones
We develop extensive paradigms – what it must meet or exceed
– and then slot them into market segments.
Our original four categories have grown to seven, and we
review against different paradigms for each category.
Premium Flagship $1600-2499 (usually a flagship
with more memory/storage, additional camera lens and now 5G)
Flagship $1000-1599 (account for about 10% of
Premium mid-market $800-999 (10% and often last
year’s flagship at run-out price)
Mid-market $500-799 (about 25% of the market)
Mass-market $200-499 (about 25% of the market)
Value pre-paid <A$199 (about 30% of the
market – good for pre-paid and children)
At $265 this fits at the lower end of the mass-market segment. Here you have the competition including LG K8 ($199), Nokia 2.2 ($199), LG K50 ($269), Huawei Y7 Pro ($269), OPPO AX5s ($279), Samsung Galaxy A20 ($279) and Nokia 4.2 ($299).
The basket of features in the Mintt UltraMintt X3 make it an offering you should consider.

The first impression – Mintt UltraMintt X3
It is a 2.5 (curved edge), waterdrop glass slab with a
pretty cobalt blue gradient back – yes, it is a HUGE fingerprint magnet.
The back is 2.5D mirror metallic (probably painted polycarbonate) over a similar synthetic frame.
Dual cameras sit in the middle centre with a single LED
flash below. There is a rear fingerprint sensor with the MIntt OK logo are
It has a pre-fitted screen protector and smallish bezels. Overall
it appears well made and durable. It is a cut above the typical mass-market
The Helio P22 processor (2018) is often compared to Qualcomm SD430 or 450 found in mass-market devices. It uses eight lower power A53 cores in two banks – Big/Little style.
We have not seen the Helio P22 before, but it is in the Motorola E6, LG K40, Nokia 3.1 Plus, Alcatel 5V, and many more phones mainly sold it the Indian, Asian or Chinese markets.
The new version of Geek Bench 5 has changed ratings that appear approx. 80% lower than GeekBench4 (multiply by five).
The single/multi-core are 142/750. The Mintt UltraMintt Y3
has 276/1372, so if you need twice the power, it costs
We found it quite smooth, but you will notice it slows with any CPU/GPU intensive app. We put that down to 3GB of RAM, but hey, it will still run Android 10.
It would not run GeekBench 5 Compute
benchmark – we suspect this is to do with the non-standard GPU.
GPU: The PowerVR Rogue GE8320 handles a 720p screen nicely. It is most often compared to a Qualcomm Adreno 4XX but in our benchmarking it was about 30% slower on most video tasks.
Game use: The CPU/GPU is not great for games. It should support most 2D mobile games to 25fps.
Throttling: A 15-minute test went from 71,447GIPS to 58,872GIPS (Average 64,446) effectively keeping 94% capacity after four minutes. There is always some throttling, but this reflects good heat management.
Temperature: at 100% load for 15 minutes the SoC reaches 62°
(internal), but the battery and other components are no more than 32°. Outside
it is even cooler at 10° (ambient inside temperature 17°). This is all within
Summary: Our only issue is that
MediaTek SoCs don’t play well with our testing software. However, it is a
decent SoC commonly found in mass-market devices.
Wi-Fi N, dual-band, MIMO
USB-C Type 1.0
Yes A-GPS and e-compass
Using Cell Info the 5GHz Signal strength at 5 meters from
our reference D-Link AC5300 router is -54dBm and 78Mbps (about as much as you
can expect for Wi-Fi N 5GHz).
GPS is accurate to within 10 metres, but as it uses A-GPS to locate satellites, it can take a minute or more. It is adequate for turn-by-turn navigation and route recalculation if you are not in a hurry!
Summary: Few phones this price offer 5Ghz N band so it will
move data faster over dual-band Wi-Fi.
Dual sim (hybrid) can use both at once or one for microSD
VoLTE: depends on carrier
Wi-FI Calling: No
Signal strength is excellent at -89dBm. Our reference
Samsung Galaxy Note9 is -101dBm (lower
is better) – this is great in a weak reception area.
As I have come to expect of 2019 technology, the UltraMintt X3 found the next nearest Telco tower at -95dBM (the Note9 does not).
That this is a phone for Australia but lacks band 40 (that may affect Optus users in Canberra).
It does not have many world LTE bands activated.
Summary: Good strong reception
3.5mm audio jack: Yes Earpiece: above the notch Speaker: down-firing mono Mics – 2 Buds: 3.5mm buds/mic FM Radio: yes
Handsfree is clear but a little low volume
Ring 80+dB (above average), Voice 73dB, Music 76dB
There are three tests – 3.5mm buds, BT headphones and the
The 3.5mm buds are average at best. I cannot measure frequency response, but there is no hint of bass, peaking mids and limited treble – mid-centric for clear voice.
Our reference Sony WH-1000Xm3 are wasted on SDB Codecs but
we use them to detect crosstalk ad maximum volume. BT 5.0 is a nice touch (at
this price), and the sound is clear, undistorted and strong.
Speaker sound signature
We use spectrum analysis to determine the sound signature of the down-firing mono speaker. We make it clear that few, if any, lower-priced phones have a decent speaker.
Frequency response is from 20Hz to 20kHz
Deep Bass: 20-40Hz – none
Middle Bass: 40-100Hz – none
High Bass: 100 to 200Hz – none
Low-mids: 200-400Hz – none
Mids: 400-1000Hz – building
High-mids: 1-2kHz – building
Low-treble: 2-4kHz – flat
Treble: 4-6kHz – declining
High Treble: 6-10kHz – declining
Dog whistle: 10-20kHz – none
This is a ‘tinny’ analytical signature, way too harsh for music pleasure.
4050 mAh battery (reported as 3950)
Charger type: 5V/2A (10W) USB-C
Quick Charge: Supports 5V/3A and 9V/2A (18W) with optional charger
Our test software indicates a 3950mAh battery – that is not
so much of an issue as batteries are typically rated at nominal capacity.
Recharge with the standard 5V/2A charger from 0-100% takes under four hours. This is a little slower than the claimed 2.5 hours but acceptable. PS: Mintt please let your markets know that 5V/2A is not ‘quick charging’.
If you buy am 18W USB-PD 2.0 charger, you can get 50% in 45
minutes and the remainder in around two hours.
1080p Video loop: 50% brightness, Airplane mode – 9 hours (this is an estimate extrapolated from two hours use)
Heavy use: screen on time – 6 hours (ditto)
GFX Bench T-Rex test: 7.53 hours
The battery is large for this class of device. We expect it to go 24-36 hours
under typical use.

155.4 x 71.8 x 8.1mmx 175.8g
2-years Australia Post swap warranty
Not provided and not listed on its website; however, the Blu G9 has stringent US FCC certification that requires SAR levels. This is .61 W/kg head and .34 W/kg body and is significantly under the maximum regulated SAR levels.
It is well made, no gaps and no #bendgate. The 2-year swap
warranty via Australia-post is good. Although in practice you first send your
phone back for a quick assessment and if it is a warranty claim (not user
caused) a replacement is immediately sent. We understand that the process takes
less than a week. Mintt claims a .05% failure rate – that is excellent.
Mintt does not have many accessories. You can buy a Pleather flip case for $29, and you can buy Blu G9 accessories at most online markets.

2D Face Unlock
The fingerprint reader is reliable and fast.
The 2D facial recognition is slow and mostly unusable in all
but good light as there is no LCD fill or IR. You can only register one face
despite multiple account capability.

At the time of review
5 June 2019
The Ultramintt X3 will receive an Android 10 upgrade when
available. The security patch is two steps behind – most Android phones should
have August by now.
Transfer from other devices
As it is pure Google Android, you need to back up your old
device to Google Cloud, and it will reinstall most apps and data to the new
What is missing
At $265 neither are deal-breakers. You could be picky and
ask for an 18W fast charger in the box, but hey, that probably saves $20!

Why the detail?
Its is vital for us to know the sensor brand and model so we
can compare it to others using the same sensors – a benchmark that allows us to
assess post-processing and lens quality as well.
The Sony IMX214 is an old BSI sensor from October 2014. It was popular in 2015 on premium phones like the Moto Z, HTC One M9, Huawei Mate 7 etc. Today it is a low-cost 13MP sensor and not with the latest smarts.
A ‘new’ feature at this time was HDR. That is reflected in the camera having a manual HDR setting (not auto as later sensors have). If you use this setting, it takes two images with SME-HDR using different exposure conditions and post-image processing generates an ‘optimal’ 13MP HDR image. It is not up to HDR standard of later sensors.
It is one
of the first sensors to support pixel binning, where the best four pixels in four
images are ‘binned’ to create a better final image. It also ‘effectively’
doubles the pixel size for low light. We assume that if you don’t use the HDR setting
it automatically pixel bins.
cannot identify the front camera sensor at present.
Mintt advertises a 52MP mode – sorry this is just rubbish. It takes the 13MP image and upscales it, quite slowly, by creating three identical pixels around each original pixel. It does not add detail (you can’t create what is not there) and softens the image.
We have not worked out how its night mode works either. It suggests that it combines three frames at different exposures, but all we see is a little brightening at the expense of detail and contrast. But file sizes are two to three times normal so let’s leave it at that.
Summary: Given this is a new brand, the best advice I can give is to be accurate and open with specifications. But at $265 it is all about whether the camera output is merely social media standard or more.
It identifies scenes including
We found that it identified the Sky quite well, but if
anything it muted the colours. We found it is best to shoot without AI.
Tests – all auto
Colours are more natural than they Mintt Y3 but still lack
the punch. – there is a little more green in the forest
and blue in the sky.
Now look at HDR
Telephoto: Detail is good, but that characteristic warm
Indoors Office Light (400 lumens)
Good detail and the
reds and colours are reasonably accurate.
Low light (room with less than 100 lumens)
The standard shot is not too bad but the colours are washed out and there are noise artifacts.
Night mode brings out the and improves details – great
No fill flash – face recognition needs decent light
8MP selfies should be outlawed. It is a basic selfie camera without flash or LCD fill.
Face detection was impossible in all but good light.
The rear camera has a 2MP depth camera for foreground/background blurring. It is OK but lacks a clear delineation where the foreground is not clearly defined.
The front 8MP camera supports bokeh but its all done post processing and is barely adequate.
Perhaps not ironically most people never use bokeh.
Maximum 1920 x [email protected] Colours are warmish, and details are quite good. The Helio P22 provides a level of EIS.
Rear camera summary
Better than most mass-market devices – great in day and office light using HDR. Not to bad in low light either.
GadgetGuy’s take – Mintt Ultramintt X3 offers goods value at $265
It is nowhere as
impressive as its brother the UltraMintt Y3 which blows me out of the water for
what a $399 phone can do.
But I have to pinch myself
and come back to reality – this is a $265 phone and it meets or exceeds any
expectations you should have.
And looking at JB Hi-Fi for price competitors there are none with the basket of features this phone has. In fact, you would need to spend $349 to get the OPPO AX7 which is the closest match to the Mintt X3 specifications.
