In the crowded budget smartphone market, the Infinix SMART 20 and vivo Y04s stand out as strong contenders. Both offer attractive features at a price around $70-$80, but their strengths target different user preferences. Choosing between them requires understanding their design, performance, camera capabilities, and battery life.
Design, Display, and Comfort
The Infinix SMART 20 and vivo Y04s feature modern designs with elongated bodies and rounded corners. Infinix presents bold color options like Shadow Black, Polaris Titanium, Sunlike Orange, and Cloudline Blue. Vivo leans towards elegance with Crystal Purple and Jade Green variants. Both phones use plastic bodies with smooth finishing that feels solid for their price segments.
When it comes to displays, Infinix SMART 20 sports a 6.78-inch IPS LCD panel with HD+ resolution and a 120 Hz refresh rate. This is quite impressive in this price range, offering a smoother visual experience when scrolling or gaming. Additionally, it reaches a brightness level of 700 nits (HBM), making outdoor use comfortable. In contrast, the vivo Y04s has a slightly smaller 6.74-inch LCD HD+ screen with an adaptive refresh rate between 60 Hz and 90 Hz and maximum brightness up to 570 nits. This makes its display less fluid but still adequate for daily usage. Ergonomically, both have IP64 certification for dust and splash resistance and side-mounted fingerprint sensors. Vivo’s Y04s measures 167.3 x 76.95 x 8.19 mm and weighs about 202 grams, while Infinix SMART 20 is slightly larger at 167.7 x 78.8 x 7.7 mm but thinner.
Performance and Memory
The Infinix SMART 20 runs on the MediaTek Helio G81 Ultimate chipset with an octa-core CPU setup—two Cortex-A75 cores at 2.0 GHz and six Cortex-A55 cores at 1.8 GHz—paired with Mali-G52 GPU. The vivo Y04s uses the Unisoc T612, also an octa-core with two cores at 1.8 GHz and six at 1.8 GHz, backed by Mali-G52 MP1 GPU. The extra Cortex-A75 cores on the SMART 20 provide a slight edge in multitasking and casual gaming.
Both smartphones come with 4 GB RAM (LPDDR4X) and storage options of either 64 GB or 128 GB eMMC 5.1. They support microSD expansion—up to 2 TB for Infinix and 1 TB for vivo, offering ample room for apps and media. Notably, vivo Y04s includes an Extended RAM feature, allowing an additional 4 GB virtual RAM, which helps apps stay active longer and improves multitasking stability.
In software, Infinix SMART 20 runs Android 16 with XOS 16 skin, providing a fresh interface and access to new Android features. Vivo Y04s operates on Android 14 wrapped in Funtouch OS 14, a mature ecosystem with camera modes, power-saving options, and an adaptive user interface. From an OS support perspective, SMART 20 may receive more updates in the future.
Camera and Multimedia
The vivo Y04s boasts a dual-camera setup, featuring a 13 MP main sensor with PDAF (phase detection autofocus) plus a QVGA secondary sensor. It supports modes like night, panorama, and 1080p video recording at 30 fps. Its 5 MP front camera is suitable for video calls and casual selfies.
The Infinix SMART 20 carries a simpler single 8 MP rear camera with dual-LED flash and video recording capability up to 1440p at 30 fps. Its front camera is also 8 MP. The higher video resolution on SMART 20 appeals to vloggers and users who prioritize video capture. However, vivo’s stronger rear camera and night mode give it the upper hand for daily photography, especially in low-light conditions.
On the audio front, vivo Y04s promotes enhanced sound features, including a 200% volume boost. Both phones have dual-band Wi-Fi, Bluetooth, USB 2.0 ports, FM radio, GPS, and OTG support, making them practical for everyday use. The SMART 20’s 120 Hz screen improves video streaming and gaming immersion.
Battery and Additional Features
Battery capacity is a key consideration at this price. The vivo Y04s houses a larger 6000 mAh battery with 15W FlashCharge, promising up to two days of use. This aligns well with users who need longer unplugged durations. Infinix SMART 20 offers a 5200 mAh battery with 15W wired charging, sufficient for a full day of multimedia and social media activities but with less endurance compared to vivo.
Both devices carry IP64 ratings for dust and water splash resistance and side fingerprint scanners. The Infinix SMART 20 distinguishes itself through UltraLink Communication technology, enhanced voice call clarity via Voiceprint Noise Reduction, and drop resistance up to 1.5 meters, providing durability advantages for daily handling.
In terms of everyday experience, SMART 20’s 120 Hz display and MediaTek Helio G81 chipset cater to younger users and content consumers seeking fluid visuals and decent gaming performance. Vivo Y04s is tailored more toward users who prioritize battery longevity and reliable photography.
