Infinix Hot 40 Pro review

Big display on a budget

The Infinix Hot 40 Pro is built around a big 6.78-inch IPS LCD panel with a standard 1080 x 2460px resolution and support for 120Hz refresh rate. Nothing too fancy, but it gets the job done, and it's what you'll normally expect from this class.

Notably, since this is an LCD panel, there are some halos along the edges, but they are more prominent around the selfie camera cutout. It's not something to stress about, but we wanted to mention it.

When it comes to brightness, the display can go up to 450 nits in manual mode and can boost up to 534 nits in auto mode. It should be enough for well-lit or somewhat sunny environments, but you may struggle to see some of the content under bright sunlight.

Contrast, on the other hand, is pretty high - 1:1822, which is enough to produce pretty deep blacks.

Still, at the end of the day, you will be able to find smartphones with brighter OLED panels for the same asking price. They are a rare find but still accessible.

Battery life

The Infinix Hot 40 Pro runs on a not-so-demanding Helio G99 chip and draws power from a standard 5,000 mAh battery. The Active Use Score seems solid enough on the surface and even gets close to the Moto G54 Power with a 6,000 mAh battery.

However, the call runtime score seems to be doing most of the heavy lifting. We say most because the web browsing runtime is pretty solid, too and the video playback time is respectable.

Charging speed

The Infinix Hot 40 Pro supports 33W fast charging, provided by the included charger and cable inside the retail box. When it comes to real-world performance, the device seems to be mostly on par with the competition or even outpace some of its direct rivals from Samsung, for example.

In the first 30 minutes, the handset gets about half of its battery charge back, while a full charging cycle takes 1 hour and 25 minutes. For the asking price, that's a respectable charging speed.

Speakers

The Hot 40 Pro offers a pair of speakers, which is a rare find in this price bracket, and as expected, it's a hybrid setup. The bottom speaker is a full-fledged speaker, while the top one acts as an earpiece as well. This means the bottom speaker will always sound fuller and louder.

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.

Speaking of, speakers punch above their class with an impressive -24.5 LUFS. For the most part, we can say the same about quality, too. Our only complaint is the lack of fullness, or bass, but we can't expect a punchy sound considering the budget. All in all, nice speakers.
