Infinix Note 50 Pro 4G review

Display

The Infinix Note 50 Pro 4G features a 6.78-inch AMOLED screen with 2,436 x 1,080 pixels resolution (393ppi). The panel supports 10-bit color depth and 144Hz refresh rate, 180Hz touch sampling, 2160Hz PWM dimming, as well as DCI-P3 color space coverage.

The advertised numbers are 550nits for typical, 1,000nits for high maximum, and 1,300 nits for peak brightness.

Let's start with our max brightness measurements. We captured 556 nits of maximum manual and 1,054 nits of maximum automatic brightness (with sunlight boost ON). These numbers are in line with the advertised ones.

The minimum brightness at white color was 2.1 nits.

The Note 50 Pro 4G supports up to 144Hz refresh rate with Infinix is listing three supported steps - 60Hz, 120Hz and 144Hz.

There are three options - Standard (fixed 60Hz), High (144Hz), and Auto Switch (120Hz). The phone will drop to 60Hz if you don't touch it for a while when using High and Auto - standard behavior.

The only thing missing here from the display specs here is the HDR video support. The phone still comes with Widevine L1 DRM, so you can stream 1080p or more in apps such as Netflix, YouTube, Prime Video.

Battery life

The Infinix Note 50 Pro 4G is powered by a 5,200mAh battery. We have completed our battery life test and the results came out about average. The phone scored an Active Use Rating of 11:26h, which is not bad, but not great either. The call time is fine, and so are the web and video streaming, but the gaming is below the average in this class.

As we said, the times are good, we've just witnessed better.

Charging speed

The Infinix Note 50 Pro 4G supports 90W wired and up to 30W wireless charging. The phone ships with a 90W charger, and you may even get a bundle with a 20W MagPad wireless pad. You can choose between 20W and 30W MagCharge pads on Infinix web store.

Infinix has implemented three charging modes - Hyper, Smart, and Low-Temp. As a default, you can have either Smart or Low-Temp, which is selected from the battery settings. The fastest one, Hyper, is only available from the Lock Screen once you start charging. At first, we thought it a bit of a hassle having to turn on fast charging explicitly every time, but then we realized this setup might be more sparing to the battery longevity while remaining flexible enough for the times you really need the speediest possible charging.

Charging options

And charging here is quite speedy indeed. Using the bundled 90W power adapter and Hyper mode, we clocked 0-88% in 30 minutes and 100% in 37 minutes. The regular Smart mode was a little slower but not shabby either (75% at the half-hour checkpoint, 45 minutes to 100%).

Since our Infinix Note 50 Pro arrived in a bundle with a 20W MagCharge pad, we also gave the wireless charging a go. For the magnets of the puck to align precisely with the phone's induction coil, you'd need to be using the case that's included with the handset (or another compatible one). Using that case is not a requirement for maxing out the speed, it's just a lot easier to align the charging coil correctly that way.

Anyway, the 20W MagPad recharges 31% in 30 minutes and 100% in 1 hour and 51 minutes. You can alternatively buy a 30W MagPad for faster wireless charging.

The Note 50 Pro 4G supports reverse charging too, both wired and wireless. There's also a bypass charging toggle, which will make the phone skip the battery charging circuitry and only draw enough power for its current tasks - could come in handy in extended gaming sessions where the extra heat of the charging process could be detrimental to performance.

Here, there aren't any other options like you'd find on other phones - for example, for limiting the charge to 80% or similar.

Speakers - loudness and quality

The Infinix Note 50 Pro 4G has stereo speakers tuned by JBL, and you can even see the JBL logo at the top of the phone. The two speakers are placed at the top and bottom of the phone, and the one at the top also has a front-facing outlet for earpiece purposes.

Each speaker plays its own track plus the opposite channel's track at a lower volume, and the phone adjusts the channels depending on its orientation. The bottom speaker is a bit more powerful, as usual.

The speakers on the Note 50 Pro 4G scored a Very Good mark on our loudness test. Their audio quality is average, though. The high frequencies are very well presented, the vocals are alright though nothing impressive, and the bass is almost non-existent.

Use the Playback controls to listen to the phone sample recordings (best use headphones). We measure the average loudness of the speakers in LUFS. A lower absolute value means a louder sound. A look at the frequency response chart will tell you how far off the ideal "0db" flat line is the reproduction of the bass, treble, and mid frequencies. You can add more phones to compare how they differ. The scores and ratings are not comparable with our older loudspeaker test. Learn more about how we test here.
