This is a ‘tinny’ analytical signature, way too harsh for music pleasure.
|Battery||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
Summary: The battery is large for this class of device. We expect it to go 24-36 hours under typical use.

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 device.
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.
