FAQs
How does the Infinix Smart 9 perform in daily usage and gaming?
The Infinix Smart 9, powered by the MediaTek Helio G81 chipset and Mali-G52 MC2 GPU, delivers a decent performance for a budget smartphone. It can handle day-to-day tasks such as browsing, social media, messaging, and streaming videos without significant lag. The 3 GB LPDDR4X RAM ensures smooth multitasking, but it may struggle with extensive app switching or heavy workloads.
For gaming, the device is capable of running casual and moderately demanding games like PUBG Mobile, Call of Duty: Mobile, and Asphalt 9 on low to medium settings. The 120 Hz refresh rate enhances the gaming experience by making animations and transitions smoother. However, due to limited RAM and HD+ resolution, high-end games might experience occasional frame drops or longer load times. The Game Mode feature in XOS also helps optimize performance by minimizing background processes and enhancing responsiveness.
What is the battery life like on the Infinix Smart 9, and how fast does it charge?
The Infinix Smart 9 is equipped with a massive 5000 mAh battery, ensuring excellent battery life for an entire day or more, depending on usage. With moderate usage, including social media, video streaming, web browsing, and occasional gaming, the phone can easily last up to 1.5 days. For light users, it could even stretch to two full days without needing a charge.
However, one downside is that the phone does not support fast charging. While it has a USB Type-C port, the charging speed is limited, meaning a full charge may take around 2.5 to 3 hours. It would have been better if the device supported at least 18W fast charging to reduce the downtime. Despite this, the battery life remains a strong point, making the Smart 9 ideal for users who prioritize longevity over fast-charging capabilities.
How good is the camera performance on the Infinix Smart 9?
The Infinix Smart 9 features a dual-camera setup on the rear, consisting of a 13 MP primary camera with an f/1.85 aperture. The main sensor is supported by a dual LED flash, which helps improve low-light photography. The phone captures decent images in well-lit conditions, delivering good color accuracy and detail for its price range. The camera also offers digital zoom and autofocus, allowing users to take slightly sharper shots.
However, in low-light conditions, the image quality tends to degrade, with noticeable noise and reduced sharpness. The LED flash helps illuminate subjects, but it does not compare to night modes found in more expensive smartphones.
The front-facing 8 MP selfie camera does a decent job in daylight and offers an LED flash for improved low-light selfies. It also includes AI enhancements for beautification, but users looking for highly detailed selfies may find the quality average. Both front and rear cameras support Full HD (1080p) video recording at 30 FPS, making it suitable for casual video capturing but not ideal for professional-level vlogging or content creation.
Is the Infinix Smart 9 a good choice for multimedia consumption?
Yes, the Infinix Smart 9 offers a solid multimedia experience, especially considering its budget-friendly price. The 6.7-inch IPS LCD display, with a 120 Hz refresh rate, provides smooth scrolling and responsive touch input. While the 720p HD+ resolution may not be as sharp as Full HD+ displays, it still delivers good colors and contrast for watching videos, browsing, and social media use.
For audio, the device comes with stereo speakers featuring DTS Sound, which enhances the overall sound quality. While the speakers are loud enough for casual listening, they lack deep bass, making them less suitable for audiophiles. Fortunately, the phone retains the 3.5 mm headphone jack, allowing users to connect wired headphones for a better sound experience.
Additionally, the Smart 9 supports FM radio, which is a great feature for users who enjoy listening to music or news on the go without relying on an internet connection. Overall, while it may not offer a flagship-level multimedia experience, it is a great option for users who consume content on a budget.
