Display Comparison
Both the ZTE Blade A75 4G and Realme C55 feature displays with a 1264:1 contrast ratio, suggesting similar visual depth. However, the Realme C55 boasts a measured peak brightness of 659 nits, significantly exceeding what we'd expect from the A75 based on its market positioning. This higher brightness translates to better outdoor visibility. While both likely utilize IPS LCD panels, the Realme C55’s superior brightness makes it the more comfortable choice in bright environments. Details regarding PWM dimming frequency are unavailable for either device, making it difficult to assess potential eye strain for sensitive users.
Camera Comparison
Both devices list 'Photo / Video' capabilities, but lack specific details regarding sensor size or image processing. Given the budget nature of these phones, we can assume both rely on relatively basic camera setups. The absence of information suggests neither phone will excel in low-light photography. The inclusion of a 2MP macro camera on the Realme C55 is a common, but often underwhelming, feature in this price range; its utility is limited. The Realme C55 likely benefits from Mediatek’s image signal processor (ISP), potentially offering slightly better image quality than the ZTE Blade A75 4G.
Performance
The Realme C55’s Mediatek Helio G88 chipset, with its 2x2.0 GHz Cortex-A75 cores and 6x1.8 GHz Cortex-A55 cores, offers a performance advantage over the ZTE Blade A75 4G’s Unisoc T606 (2x1.6 GHz Cortex-A75 & 6x1.6 GHz Cortex-A55). The higher clock speeds on the G88’s prime cores will result in snappier app launches and smoother multitasking. Both chipsets are built on a 12nm process, so thermal efficiency should be comparable, but the G88’s slightly more powerful GPU will be beneficial for casual gaming. Neither phone is a gaming powerhouse, but the Realme C55 will handle graphically demanding titles with fewer compromises.
Battery Life
Both the ZTE Blade A75 4G and Realme C55 achieve an endurance rating of 123 hours, indicating similar overall battery life under typical usage. However, the Realme C55’s 33W wired charging significantly outperforms the ZTE Blade A75 4G’s 22.5W charging. Realme claims a 50% charge in just 29 minutes, a substantial advantage for users who need to quickly top up their battery. While both phones offer all-day battery life for moderate users, the Realme C55’s faster charging provides greater convenience.
Buying Guide
Buy the ZTE Blade A75 4G if you need a reliably basic smartphone for essential tasks like calls, messaging, and light social media use, and prioritize a lower initial cost. Buy the Realme C55 if you prefer a phone that can handle moderate multitasking, offers faster charging for quicker top-ups, and provides a slightly smoother user experience, even if it comes at a small price premium.
Frequently Asked Questions
❓ Does the Unisoc T606 in the ZTE Blade A75 4G struggle with multitasking?
The Unisoc T606 is a capable chipset for basic tasks, but it may exhibit slowdowns when handling numerous apps simultaneously. It's best suited for users who primarily use one or two apps at a time. The Realme C55's Helio G88 will handle multitasking more smoothly.
❓ How significant is the charging speed difference between 22.5W and 33W?
The 33W charging on the Realme C55 is a noticeable improvement. Realme advertises 50% charge in 29 minutes, while the ZTE Blade A75 4G will take considerably longer to reach the same level. This difference is particularly beneficial for users who frequently need to quickly top up their battery.
❓ Can the Realme C55 handle popular mobile games like PUBG Mobile?
The Realme C55 can run PUBG Mobile, but you'll likely need to lower the graphics settings to achieve a playable frame rate. The Helio G88 is not a high-end gaming chipset, so don't expect a flawless experience. The ZTE Blade A75 4G will likely struggle even more with demanding games.
❓ Is the camera on either phone suitable for taking high-quality photos in low light?
Neither the ZTE Blade A75 4G nor the Realme C55 are expected to excel in low-light photography. Both likely feature basic camera sensors and image processing capabilities. Expect noisy and underexposed photos in challenging lighting conditions.
