Infinix Hot 10S NFC Smartphone Review: 90 Hz for $120 USD

0
9

Hot and your cold. Just $120 USD can net you a fairly large 6.82-inch Android 11 smartphone and a sizeable 5000 mAh battery. There are some drawbacks, of course, but they’re nothing most budget users can’t live with.

Officially unveiled just last week, the Hot 10S NFC is the latest inexpensive smartphone from Infinix designed for users who want a large display without having to spend hundreds of dollars more. The smartphone is also notable for carrying a MediaTek Helios G85 SoC, a 90 Hz refresh rate display, triple 48 MP rear cameras, and a large 5000 mAh battery — not bad for something retailing for just $120 USD.

A second version called the Hot 10S will also be made available on May 12 with more RAM (6 GB vs. 4 GB) and an even larger battery (6000 mAh vs. 5000 mAh) for $130 USD. Both versions are planned for Indonesia, Russia, and Latin America in Black, Green, Ocean, and Purple color options.

The first thing users will notice is how large the Hot 10S is. Consequently, it’s also slightly heavier and larger than many alternatives including the Samsung Galaxy A52 or Doogee X95 Pro. Build quality is otherwise nothing special with its glossy plastic back and rounded edges and corners. Our specific test unit exhibits no faulty construction or unintended gaps along the sides.

The IPS display excels in a few aspects while falling behind in others. Contrast ratio, for example, is high for excellent black levels when viewing videos and the fast 90 Hz refresh rate makes the display more responsive to the touch. On the other hand, black-white and gray-gray response times are slow meaning ghosting is noticeable when scrolling through web pages.

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.

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 not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9670 (minimum: 5 – maximum: 151500) Hz was measured.

Raw CPU performance is most similar to the Snapdragon 720 while graphics performance is only half that of the Helio 90T. It’s good enough for most Play Store games including Mario Kart Tour, but more demanding titles like Genshin Impact will have shaky frame rates and plenty of frame skips.

Though MicroSD cards are supported, the reader didn’t seem to be working on our review unit. Transfer rates were abnormally slow at less than 2 MB/s even after several retries with different MicroSD cards.

Runtimes are long at over 12 hours of real-world WLAN use thanks to the large 5000 mAh battery. Charging is also decently fast from 15 percent to 73 percent in 90 minutes with the included AC adapter.

In review: Infinix Hot 10S NFC. Test unit provided by Infinix

The Hot 10S is one of the better smartphones in its super-cheap price range. Many of its disadvantages, including the noticeable ghosting, unremarkable native resolution, and heavy bloatware, are easy to live with for those who just want a large smartphone with an equally large display. The decent Helio G85 SoC and 90 Hz refresh rate help to make the smartphone feel faster than it really is when compared to others in its category for browsing and the occasional light gaming.

Cheap, long-lasting, and big for users who want to maximize value per dollar. However, you’re likely going to uninstall all the distracting bloatware as soon as you can.

The Hot 10S and Hot 10S NFC will become widely available starting on May 14 in select regions.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There’s a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I’m not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
