Weaknesses

The Mediatek Helio G35 chipset, although decent for this price segment, may not provide the best gaming experience.
The phone has an average camera setup with noisy and grainy indoor photos, but performs better in outdoor situations.
The charging speed is a concern due to the 10W power brick that takes time to charge the 5000mAh battery.

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 C25s

The Realme C25s is the latest release in the Philippines, and it's essentially an upgraded version of the original C25 that launched back in April. The main difference lies in its performance upgrade courtesy of a Mediatek Helio G85 processor, making it marginally better than its predecessor. In terms of design, the Realme C25s is identical to the C25, with a 6.5-inch IPS LCD display and a textured plastic back panel that provides a grippier surface without being prone to fingerprints or smudges. The phone's build quality feels budget-friendly, but it does come with some nice touches like a free black-tinted jelly case and a USB Type-C cable. One of the notable upgrades on the C25s is its display, which boasts a peak brightness of 570 nits - an improvement over the original C25 that only reached 480 nits. However, aside from this, the display quality remains pretty much the same as other entry-level IPS panels, with decent colors, contrast, and viewing angles. The camera setup on the Realme C25s consists of a 48-megapixel main sensor, a 2-megapixel depth sensor, and a 2-megapixel macro camera - the same configuration as the original C25. Performance-wise, the Helio G85 processor provides only a slight upgrade over the G70 in the C25, with the biggest jump being a 1000 MHz GPU turbo speed. Priced at ₱7,490 for the 4GB+64GB model and ₱8,490 for the 4GB+128GB variant, the Realme C25s feels like an unnecessary upgrade over its predecessor. Nevertheless, it's still a solid budget offering with a large 6000mAh battery and decent display quality. If you're in the market for a budget phone with a good-sized screen and adequate performance, the Realme C25s might be worth considering - but only if you can't find any other better options at this price point.
