The Infinix Hot S3X comes with a 4000mAh built-in battery and the company bundled a 10W charger within the box. This is a massive battery in comparison and should last one single day easily even with continuous usage. Just as you would expect, the Hot S3X, during our testing could last more than just a day with moderate to slight heavy usage. Our usual working day includes use cases like taking calls, listen to music, play games, GPS navigation, click pictures, stream videos. With this kind of usage, the phone was able to last two days straight. We didn’t notice any idle battery drain or a drastic drop.
On the other hand, with heavy usage that includes continuous gaming, watching movies or browsing with 4G, GPS navigation, edit photos, the phone had no issues lasting a single day. It resulted in a screen on time of around 5-6 hours. It managed to last about 11 hours during our HD video loop test. If you are a heavy user, you will have to charge once again to pull through to the end of the day. The good thing about the battery is that it doesn’t drain much on heavy usage as well. While the screen time is not the very exceptional, but then again it isn’t very bad either. Since it does come with 10W charger within the box, the phone took close to 2 hours 15 minutes of time to charge fully from 1% to 100%. Overall, the battery department of the Infinix Hot S3X is impressive and it is in-line with the competition in the similar price segment.
In terms of camera, the Infinix Hot S3X features a 13MP rear camera with Dual LED Flash, f/2.0 aperture and a secondary 2MP camera. On the front, it has a 16MP front-facing camera with Soft-LED flash, f/2.0 aperture, AI Bokeh, AI Beauty, WideSelfie. It comes with basic features like Portrait, Panorama, and Night. The camera app which is version 3.0 is fairly simple, it has toggles for HDR, delayed capture, touch capture, grid, watermark, and more. To our disappointment, there is no PRO mode. Moving along, the camera performance is decent given the good daylight conditions. The color reproduction and the overall clarity of the image are acceptable. The brightness and contrast levels are well balanced. The exposure levels in landscapes and bokeh in macro shots are fine too. We didn’t notice any focusing issues, but certain shots take time for processing. The portrait mode is good, but you can’t preview the amount of blur while clicking the photo, so it might result in photos that are not in focus which can get frustrating. The low-light shots are decent. The phone could take good portrait shots even at night. But the landscape shots were not that impressive during night time. The rear camera can record 1080p videos and the quality is decent enough.
There is a 16-megapixel fixed-focus front camera. But the quality of selfie is mixed. It could take sharp and crisp images, but the exposure is too artificial to our liking. The beauty mode is aggressive and few might like it. The front-facing LED flash helps when taking selfies in low-light conditions. The good thing about the front camera is that it could record 1080p videos which are decent. Overall, the cameras of the Infinix Hot S3X is decent and surely better than most phones in this segment.
The budget segment in India is becoming a serious issue for any smartphone manufacturer to top. However, the Infinix Hot S3X is not a huge upgrade nor a worthy phone to consider given the pricing. It packs an age-old chipset that is very underpowered at this price point, just has a 720p display, a notch display with a sizeable chin which looks ugly. However, on the good side, the phone has a decent set of cameras, stunning looks appealing to the mass audience in India. So, if you are in the market looking for a phone in the sub Rs. 10,000 price segment, you can go with the Asus Zenfone Max M2.
The Infinix Hot S3X is powered by the Qualcomm Snapdragon 430 SoC 64-bit Mobile Platform clocked at 1.5GHz Octa-Core processor with Adreno 505 GPU and 3GB/4GB RAM. Unlike the Snapdragon 425, 430 is an Octa-Core chipset and was able to pull off daily essential tasks like taking calls, sending text messages, browsing, and social media apps as well. It could handle multitasking smoothly with around 5-6 apps, but started lagging if you push it with more number of apps than it can handle. Since the interface is very heavy, we did notice occasional lag and stutters in the UI and this can get annoying as you keep using the phone. However, it offers smoother transitions and animations. Always clear out the unused apps or inactive apps from the background so you will have enough RAM to run apps smoothly.
In the gaming department, the Infinix Hot S3X produced average results. It was able to run PUBG, Asphalt 8, Leo’s Fortune, and more, but with medium graphic settings only. Since the phone costs Rs. 9,999, there are better phones like the Zenfone Max Pro M1, M2 with a much better gaming experience. It comes with a fingerprint sensor that unlocks the phone quickly without any delay in animations as well. Overall, the performance of the Infinix Hot S3X is not very impressive, the company could have included a better chipset.
Hong Kong-based Transsion Holdings' Infinix brand is relatively new to the country and the company has been launching phones in various price segments consistently despite having a low market share. Recently it launched the HOT S3X in its Hot series. The phone comes with a larger display meaning a notch, dual rear cameras, and an improved selfie camera compared to its predecessor. With the upgraded pricing and design, can the HOT S3X succeed like its predecessor? We will find that out in our today’s review. Let’s get started.
The Infinix HOT S3X sports a 6.2-inches HD+ (720 x 1500 pixels) 2.5D curved glass display with a 19:9 aspect ratio. It is powered by the Qualcomm Snapdragon Snapdragon 430 Mobile Platform SoC clocked at 1.4GHz Octa-Core processor with Adreno 505 GPU. It packs up to 4GB RAM and 64GB storage that is expandable up to 128GB with microSD. It runs on Android 8.1 Oreo with Hummingbird XOS 3.3 on top.
In terms of camera, the Infinix Hot S3X features a 13MP rear camera with Dual LED Flash, f/2.0 aperture and a secondary 2MP camera. On the front, it has a 16MP front-facing camera with Soft-LED flash, f/2.0 aperture, AI Bokeh, AI Beauty, WideSelfie. The phone comes with a Fingerprint sensor, and a face unlocks. Connectivity features include Dual 4G VoLTE, Wi-Fi 802.11 b/g/n 2.4GHz, Bluetooth 4.2, and GPS. A 4000mAh battery.
The company didn’t bundle earphones within the box, so you will have to invest some more in a pair of decent earphones for the better sound experience. The speaker grill is present on the bottom and was able to cover an entire room, and we never missed a call. The default audio player was able to play most audio formats without any issues. We didn’t hear any distortion even when the volume is kept at a maximum. The sound experience is decent when tested with the headphones we had with us.
In terms of video, the Infinix Hot S3X was able to handle 1080p videos without any heating or freezing issues. Even with 4G turned on, we didn’t notice any heating issues. For better aspect ratio, it is for best if you install MX Player. Overall, as we mentioned above, you will have to invest some more bucks on a pair of earphones for better audio and video quality.
The Infinix Hot S3X runs on Android 8.1 Oreo with Hummingbird XOS 3.3 on top. Like with most smartphones, it doesn’t come with any app drawer, instead, all the apps are arranged on the home screen. If you are not a fan of such arrangement, you can download the custom launcher from Play Store. While we can live with the interface, the rounded square shape for all icons is just ugly to look at. It just doesn’t adhere to the overall design scheme. While it comes with native Google applications, the default apps like phone, messages, camera, weather, and messages are custom. It also comes with Carlcare for after-sales support, XHide to hide pictures, videos, and voice recordings; XTheme app where you can download themes to change look and feel of the UI when you get bored with the current look. It also comes with XClub customer forum, freezer app to free up RAM. These apps can’t be pre-installed unless you are rooted.
It also brings gestures, instead of on-screen navigation buttons and these can be accessed from system settings. You can swipe up from the middle-bottom to go to home screen, swipe up from the bottom left to open the app switcher, and swipe up from the bottom right to go back. There is no way you can hide the notch so you will have to rely on it. It comes with 3GB/4GB RAM out of which around 1.5GB RAM is free when the default services are running in the background. It was able to handle multitasking with up to 4-5 apps without any issues. Apps never ran out of memory and it is a good thing. Overall, the software department of the Infinix Hot S3X is decent.
The Infinix Hot S3X is quite a looker and it is no exaggeration when we say it is one of the better-looking phones in this price segment. It packs a glass back and looks stunning especially in the blue color. Despite being 6.2-inches, the phone fits perfectly in hands and we were able to reach all corners of the phone even with a single hand. The frame running on all corners is plastic and offers a good grip to hold in hands. The glass shines in various forms when titled and it looks stunning. Since the glass back is very glossy, it attracts fingerprints very quickly, making you wipe constantly. The phone isn’t very heavy at 150 grams. The company did a good job by including plastic frame all on corners as it helps in better signal reception and heat dissipation.
Moving to placements, up front, the Infinix Hot S3X packs a regular notch where the 16MP front camera is present, along with earpiece. The phone comes with a 19:9 aspect ratio. The volume rockers and the power button are present on the right side. There is the SIM tray and dedicated microSD card slot on the left. The Micro-USB port, speaker grille, and a microphone are placed on the bottom, while the 3.5mm headphone jack is on top. On the back, it has a 13MP+2MP dual cameras, LED flash, Infinix logo, and fingerprint sensor. Overall, the Infinix Hot S3X design and build are definitely superior considering the pricing.
The Infinix HOT S3X sports a 6.2-inches HD+ (720 x 1500 pixels) 2.5D curved glass display with a 19:9 aspect ratio. There is no protected glass on top, so it is better if you install a screen protector on top. Moving along, the display on the Hot S3X offers good color reproduction. Thanks to the impressive screen to body ratio, watching videos and playing games was a pleasant experience. Though there is a notch on top, the sizeable chin on the bottom makes the whole front of the phone look ugly. viewing angles were good, we didn’t notice any color shift while tilting or distortion when viewing from extreme angles, thanks to the IPS panel.
The touch response is smooth, and we didn’t notice any lags while scrolling or browsing on Chrome either. Since it is a 720p panel, there is pixelation when zooming in images and browsing the web. The text and pictures aren’t very sharp and this is a small let-down. It comes with an auto-brightness sensor, so you don’t have to adjust the brightness all the time once it is enabled. Overall, the display of the Infinix Hot S3X is neither very impressive or too bad, it lives in the middle ground. We wish the company had bundled a 1080p panel which would have enhanced the experience further.
