The Redmi A4 5G is the safer pick for 5G, documented software support and an included charger; the POCO C75 4G can suit buyers who do not need 5G and value its listed 13MP selfie camera or lighter weight. But there is also an India-market POCO C75 5G, a different phone that makes the comparison much closer. Check the full model name before comparing prices or specifications.
First, identify which POCO C75 you mean
“POCO C75” can refer to two materially different phones. Xiaomi’s global specification sheet describes the POCO C75 4G, which does not support 5G. Indian comparison listings also identify a separate POCO C75 5G. Do not transfer the 5G model’s chipset or camera details to the 4G model—or assume every listing without a “5G” suffix identifies the same device.
The table separates both POCO versions. The Redmi A4 specifications and update promise below refer to Xiaomi India’s model, so availability and features may differ elsewhere.
| Feature | POCO C75 4G (global specification) | POCO C75 5G (India listings) | Redmi A4 5G (India) |
|---|---|---|---|
| Network and processor | 4G; global sheet identifies a MediaTek Helio G81-Ultra | 5G; listings identify Snapdragon 4s Gen 2 | 5G; Snapdragon 4s Gen 2 |

| Rear/front cameras | 50MP main / 13MP | 50MP main / 5MP in reviewed listings | 50MP f/1.8 main / 5MP in comparison data |
| Battery and charging | 5,160mAh; 18W; global sheet says adapter not included | 5,160mAh; confirm charging and box contents for the exact SKU | 5,160mAh; 18W phone charging; 33W adapter included in the India box |
| Storage and expansion | Configurations vary by market; microSD support | 64GB or 128GB listed; confirm exact configuration | 64GB or 128GB, UFS 2.2; dedicated SIM/microSD slot, expansion up to 1TB |
| Software and stated support | HyperOS; reviewed global specification sheet gives no matching update commitment | Android 14/HyperOS in comparison listings; verify policy for the SKU | Android 14 with HyperOS; Xiaomi India states two Android version updates and four years of security updates |
| Protection and weight | No IP rating in the reviewed global specification extract; about 204g in comparison data | IP52 and about 205g in comparison data | IP52; about 212.35g |

5G and performance: the model name changes the answer
Against the POCO C75 4G, the Redmi A4’s clearest advantage is connectivity: it supports 5G, while the global POCO C75 specification lists 4G, 3G and 2G only. The Redmi also uses Qualcomm’s Snapdragon 4s Gen 2 5G platform; the global C75 4G sheet identifies a different platform. If you are considering an import, verify local carrier bands, warranty and network compatibility rather than relying on the family name alone.
Against the POCO C75 5G, both phones are listed with Snapdragon 4s Gen 2 5G. That suggests broadly similar platform-level performance, not identical real-world speed: RAM configuration, storage, thermals and software tuning matter too. These are entry-level phones suited to everyday tasks such as messaging, browsing, video, payments and navigation, not choices to make on the assumption of high-end gaming performance.
5G is useful only where your carrier, plan and location support compatible bands. If you rarely have 5G coverage, a 4G model may still meet your needs, though it offers less network headroom for future use.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Display: big and smooth, but still HD+
All three versions are built around a large 6.88-inch HD+ screen with a refresh rate of up to 120Hz, based on the available specifications. That size is useful for video and reading, while a higher refresh rate can make supported scrolling and animations look smoother. It does not mean every app or game runs at 120 frames per second, and the screen may not stay at its maximum refresh rate in every mode.
HD+ resolution is a compromise on a screen this large: text and fine details will not look as crisp as they would on a higher-resolution display. Xiaomi claims 600-nit brightness for the Redmi A4. The global C75 sheet gives 450 nits typical brightness and 600 nits in HBM (a high-brightness mode), so those figures are not directly interchangeable. On paper, neither display establishes a decisive overall win.
Cameras: a POCO 4G selfie-spec advantage, not a proven photo win
Each phone is listed with a 50MP main rear camera. Xiaomi specifies an f/1.8 camera and 4-in-1 pixel binning for the Redmi A4; the global POCO C75 sheet also lists a 50MP f/1.8 main camera. Those specifications do not prove which phone takes better photos. Image processing, focus, dynamic range and low-light performance require comparable photo samples to judge.
The clearest specification difference is on the front: the global POCO C75 4G lists a 13MP selfie camera, while the Redmi A4 is listed at 5MP in comparison data. That gives the 4G POCO the stronger selfie-camera specification, not a guaranteed better selfie. Do not apply that advantage to the Indian POCO C75 5G: the reviewed listings give that model a 5MP front camera.

Each model is listed with a 5,160mAh battery, so capacity alone does not separate them. Actual endurance depends on use, brightness, refresh-rate settings, signal strength and—on 5G models—network conditions.
Rank #2
- Wonderful Design - USTIYA designed case for Xiaomi Poco C75 and for Redmi 14C allows perfect display of the phone's appearance, allowing you to appreciate its beauty and design. It shows the original color of the phone.
- The combination of flexible TPU and shock absorbing Four Corners helps protect your phone for Xiaomi Poco C75 and for Redmi 14C from drops and other impacts
- Its design with micro dots on the inside prevents the wet and sticky appearance, so common among transparent cases, thus helping to maintain the beautiful design for Xiaomi Poco C75 and for Redmi 14C
- The matte side strips of the edge can increase the stability of the grip of the mobile phone, making it comfortable to hold and preventing it from slipping, while also preventing phone corrosion from hand sweat. Easy to clean, you only need to gently wipe it with a damp cloth to remove stains and dirt.
- DIY customization: due to the special material of the transparent phone case, you can stick photos, patterns, etc. that you like on the back of the phone to personalize it and reflect your style and personality.
The Redmi A4 supports 18W phone charging, and Xiaomi India says a 33W charger is included in the box. The phone does not therefore charge at 33W. The global POCO C75 specification sheet lists 18W charging and says a power adapter is not included; package contents can vary by region. Check the exact POCO 5G package rather than assuming it follows the global 4G model.

The Redmi A4 has the clearest published long-term support commitment: Xiaomi India states two Android version updates and four years of security updates. That promise is specifically attributed to Xiaomi India; do not assume the same terms for every country, carrier or SKU. The reviewed POCO C75 global specification material does not state a matching commitment, which is an information gap—not proof that the phone will receive no updates.
Xiaomi India lists the Redmi A4 with up to 128GB of UFS 2.2 storage, a dedicated 2+1 SIM/microSD arrangement and expansion up to 1TB. Its advertised “up to 8GB RAM” includes 4GB of virtual RAM alongside 4GB physical RAM; virtual RAM uses storage and is not equivalent to 8GB of physical memory. POCO C75 RAM and storage combinations vary by market, and the 4G and 5G versions should be checked separately.
The Redmi A4 has an official IP52 rating, which indicates limited dust and dripping-water protection—not waterproofing. Xiaomi also lists a 3.5mm headphone jack and side fingerprint sensor. The global POCO C75 sheet lists those two features as well and says NFC availability varies by market. The Redmi is heavier in comparison data (about 212g versus roughly 204g for the C75 4G), a modest difference for phones of similar large-screen size.
Price and availability: compare like with like
There is no reliable universal “current price” for these phones: offers, stock and configurations vary. Third-party Indian comparison pages showed widely differing prices in August 2026, including about ₹7,965 to ₹14,498 for the Redmi A4 and roughly ₹8,499 to ₹8,990 for POCO C75 listings. These are dated offer signals, not verified fixed prices, and the C75 listings may refer to different models or configurations. See Smartprix’s comparison and GadgetsNow’s comparison; check the live retailer listing before deciding.
Compare the same country, exact model, RAM and storage, warranty and charger contents. Before importing a phone, confirm the model number, network bands, local warranty and return terms. An attractive price is not a saving if the handset lacks the bands or support you need.
Which one should you buy?
- Choose the Redmi A4 5G if you want 5G, a clearly stated India-market update policy, UFS 2.2 storage, a dedicated microSD slot, an included charger or IP52 protection—and the price is competitive for your configuration.
- Choose the POCO C75 4G if 4G is sufficient, it costs meaningfully less, you prefer a lighter phone, and the 13MP selfie camera applies to the exact model you are buying. It is a more sensible fit if you already have a compatible 18W charger, since the global package may not include one.
- Consider the POCO C75 5G if you mean the Indian 5G model and it is cheaper than the Redmi A4 or offers a better RAM/storage configuration for the same money. Confirm its camera, charging, box contents, update terms and exact variant first.
Bottom line: For most buyers choosing between the India-market 5G phones, the Redmi A4 is the better-documented option, but the POCO C75 5G can win on value if its exact configuration is cheaper. The 4G POCO C75 is a different proposition: buy it for a lower price or its listed selfie-camera advantage, not for 5G.
