realme C21

The Realme C21 is a budget-friendly smartphone that packs some impressive features, including a massive 5000mAh battery, a 6.5-inch mini-drop full screen, an instant fingerprint scanner, and a 13-megapixel triple rear camera setup. The phone's design is sleek with a geometric pattern at the back, providing a good grip and resistance to fingerprint smudges. The volume rockers and power button are located on the left side, while the sim tray and micro SD card slot are also accessible from there. Under the hood, the Realme C21 is powered by a Mediatek Helio G35 chipset, paired with 4GB of RAM and 64GB of internal storage. While not the most powerful processor, it manages to deliver decent performance for gaming and everyday tasks. The phone runs on Realme's User Interface 1.0 based on Android 10, which is simple and efficient, consuming less resources while performing well. The display is a 6.5-inch IPS LCD panel with DUV rain land certification, offering good viewing angles and a surprisingly smooth experience. In terms of performance, the phone can handle games like PUBG and Call of Duty at medium frame rates, but may not be the best choice for serious gamers, as other options in the same price bracket offer better processors. The battery life is impressive, lasting two days even under heavy usage, but charging speeds are relatively slow. The camera setup is decent for its price segment, offering a 13-megapixel rear camera and a 5-megapixel selfie shooter at the front. Indoor performance can be noisy and grainy, but outdoor shots are better quality. Overall, the Realme C21 offers a solid package of features and performance for its price, making it a good option for those on a budget.

realme C25Y

The Realme C25Y is a budget smartphone that boasts a 50-megapixel primary camera, which is a notable feature in its price range. The device's design is similar to previous C-series models, with a textured finish and a physical fingerprint sensor on the back. However, the screen resolution is only 720p, which may be disappointing for some users. The phone's camera quality is impressive, especially in bright lighting conditions. Details are sharp, colors look natural, and dynamic range is acceptable. The primary camera takes decent images, while the macro and black-and-white cameras work poorly. The selfie shooter produces good images considering its price point. However, the device's performance is let down by an entry-level Unisoc T610 chipset, which is a below-average processor for Realme. This chipset is not as powerful as those found in other budget smartphones from the brand. The phone offers 4GB of RAM and 64GB of storage, although this can be expanded with a microSD card. The battery life is a redeeming feature, with up to two days of use on a single charge, and fast charging that can top up the device in under an hour and a half. The phone runs on Android 11.0 with Realme's UI, but the display resolution could have been better. Overall, the Realme C25Y is a decent option for those looking for a budget smartphone with good camera quality and long battery life. However, its performance is hindered by an underpowered chipset, and the price point may be confusing due to these limitations.
