Display Comparison
Neither device boasts a standout display. Both likely utilize LCD panels, common in this price bracket. Detailed specs like resolution and peak brightness are missing, but the focus here is on performance. Bezels are expected to be relatively substantial on both, impacting the overall screen-to-body ratio. Color accuracy will likely be standard for the segment, prioritizing vibrancy over absolute fidelity.
Camera Comparison
Without detailed camera specifications, a direct comparison is difficult. Both phones likely feature a primary camera and potentially depth/macro sensors. The absence of OIS on either device suggests reliance on software stabilization. Image processing will likely differ, with Realme often favoring more saturated colors and Infinix potentially aiming for a more natural look. The quality of the main sensor will be the determining factor, but without megapixel counts or sensor sizes, it's impossible to declare a winner. The inclusion of 2MP macro sensors on either device is largely a marketing tactic, offering limited practical benefit.
Performance
The core difference lies in the chipsets. The Infinix Hot 60i 4G features the Mediatek Helio G81 Ultimate, built on a 12nm process, with an octa-core configuration of 2x2.0 GHz Cortex-A75 and 6x1.8 GHz Cortex-A55 cores. The Realme C51s utilizes the Unisoc Tiger T612, also 12nm, but with a slightly slower 2x1.8 GHz Cortex-A75 and 6x1.8 GHz Cortex-A55 setup. While both employ the same core architecture, the higher clock speeds of the G81 Ultimate translate to a performance advantage in CPU-intensive tasks and gaming. The G81 Ultimate's GPU is also expected to outperform the T612's, offering a smoother gaming experience. RAM configurations are crucial, but absent from the provided data; faster LPDDR4X or LPDDR5 RAM would further benefit the G81 Ultimate.
Battery Life
The Infinix Hot 60i 4G’s 45W wired charging is a significant advantage, promising a 50% charge in just 24 minutes. The Realme C51s’ 33W charging takes 28 minutes to reach 50%. While both offer respectable charging speeds, the Infinix is noticeably faster. Battery capacity is not specified, but the faster charging of the Hot 60i allows it to recover more quickly from heavy usage. The Hot 60i also includes 10W reverse wired charging, a useful feature for topping up accessories, which the C51s lacks. Bypass charging on the Hot 60i is also a plus, allowing the phone to be powered directly from the charger, reducing heat buildup during prolonged gaming sessions.
Buying Guide
Buy the Infinix Hot 60i 4G if you need a phone capable of handling moderately demanding games and applications with greater fluidity, and if minimizing charging time is a priority. Buy the Realme C51s if you prefer a slightly more streamlined software experience and are willing to trade some processing power for potentially better software optimization and a potentially lower price point (depending on regional availability).
Frequently Asked Questions
❓ Will the Infinix Hot 60i 4G handle demanding games like PUBG Mobile smoothly?
The Mediatek Helio G81 Ultimate chipset in the Infinix Hot 60i 4G is capable of running PUBG Mobile, but expect to make compromises on graphics settings. Aim for balanced or low graphics and medium frame rates for a consistently smooth experience. The bypass charging feature can also help maintain performance during extended gaming sessions by reducing heat.
❓ Does the Unisoc Tiger T612 in the Realme C51s struggle with multitasking?
The Unisoc Tiger T612 is a capable chipset for everyday tasks, but it may exhibit some slowdowns when handling numerous apps simultaneously. Closing unused applications and avoiding excessive background processes will help maintain responsiveness. It's best suited for users who primarily use a few apps at a time.
❓ How significant is the charging speed difference between 45W and 33W in real-world use?
The difference of 12W is noticeable. The Infinix Hot 60i 4G's 45W charging will get you from 0-50% in 24 minutes, while the Realme C51s takes 28 minutes. Over a full charge, this translates to a significant time saving, especially for users who frequently need to top up their phone quickly.
