Display Comparison
Display specifications are not provided, so a direct comparison is impossible. However, given the price bracket, both devices likely feature LCD panels with FHD+ resolution. The Realme C75, being slightly older, may have wider bezels. Color accuracy will likely be similar, leaning towards the warmer side to appeal to a broader audience. The absence of high refresh rates is expected in this segment.
Camera Comparison
Camera details are limited. Both phones likely feature a primary camera and depth sensor. Without knowing sensor sizes or apertures, it’s difficult to assess image quality. The Redmi Note 13R’s newer ISP (Image Signal Processor) within the Snapdragon 4+ Gen 2 could offer improved noise reduction and dynamic range. The absence of Optical Image Stabilization (OIS) is expected on both devices, meaning low-light performance will rely heavily on software processing.
Performance
The core difference lies in the chipsets. The Realme C75’s Mediatek Dimensity 6300 (6nm) utilizes two Cortex-A76 cores clocked at 2.4 GHz, paired with six Cortex-A55 cores at 2.0 GHz. The Xiaomi Redmi Note 13R features the Qualcomm Snapdragon 4+ Gen 2 (4nm) with two Cortex-A78 cores at 2.3 GHz and six Cortex-A55 cores at 1.95 GHz. The Snapdragon’s 4nm process gives it a theoretical efficiency advantage, potentially leading to cooler operation and sustained performance. While the C75’s A76 cores have a slightly higher clock speed, the A78 cores in the Redmi Note 13R generally offer better single-core performance. This translates to snappier app launches and smoother multitasking for the Redmi Note 13R.
Battery Life
The Realme C75 boasts a significant advantage in battery endurance with a reported 65:33h rating, suggesting it can comfortably last a full day even with heavy usage. Coupled with 45W wired charging, it can replenish the battery quickly. The Redmi Note 13R, with 33W charging, will take longer to fully charge. While the Redmi Note 13R’s Snapdragon 4+ Gen 2 is more efficient, the C75’s larger battery capacity and faster charging likely outweigh this benefit for most users. The C75 also claims 1000 charge cycles, suggesting long-term battery health.
Buying Guide
Buy the Realme C75 if you need exceptional battery life and fast charging capabilities, making it perfect for users who are constantly on the go or frequently use power-intensive applications. Buy the Xiaomi Redmi Note 13R if you prioritize a more modern chipset architecture for potentially better long-term software support and slightly improved efficiency in less demanding tasks, and are willing to trade some battery performance for it.
Frequently Asked Questions
❓ Will the Mediatek Dimensity 6300 in the Realme C75 struggle with demanding games like PUBG Mobile?
While the Dimensity 6300 is capable of running PUBG Mobile, you'll likely need to lower graphics settings to achieve a consistently smooth frame rate. The Snapdragon 4+ Gen 2 in the Redmi Note 13R might offer slightly better sustained performance in gaming due to its more efficient architecture, but neither phone is a dedicated gaming device.
❓ How long will it take to fully charge the Redmi Note 13R from 0% with the 33W charger?
Based on typical 33W charging speeds, expect the Redmi Note 13R to take approximately 1 hour and 45 minutes to 2 hours to fully charge from 0%. This is considerably slower than the Realme C75’s 45W charging, which should achieve a full charge in around an hour.
❓ Does the Realme C75 support reverse wired charging, and is it useful?
Yes, the Realme C75 supports 5W reverse wired charging. While not particularly fast, it can be useful for topping up accessories like wireless earbuds or a smartwatch in a pinch. It won't significantly charge another phone, but it's a convenient feature to have.
