The realme P4 5G has the more ambitious battery and charging specifications: a 7,000mAh typical battery, 80W charging and a 144Hz display. Samsung’s Galaxy A27 5G counters with optical image stabilization (OIS) on its rear camera and a clearly stated commitment to six Android OS/One UI upgrades and six years of security updates. Neither set of specifications establishes an overall winner: the better fit depends on which features matter most to you.
realme P4 vs Samsung Galaxy A27 5G: key specifications
| Specification | realme P4 5G | Samsung Galaxy A27 5G |
|---|---|---|
| Display | 6.77-inch AMOLED; up to 144Hz; 1080 × 2392 resolution | 6.7-inch Super AMOLED; up to 120Hz; 1080 × 2340 resolution |
| Battery and charging | 7,000mAh typical capacity (6,830mAh minimum); 80W charging; charging adapter listed in the box | 5,000mAh; Samsung’s purchase page says a travel adapter is not included |
| Rear cameras | 50MP main and 8MP wide-angle | 50MP, 5MP and 2MP; OIS listed on the rear camera |
| Front camera | 16MP | 12MP |
| Processor | MediaTek Dimensity 7400 Ultra; realme also promotes a dedicated graphics chip | Snapdragon 6 Gen 3, according to Samsung’s launch announcement |
| Software and updates | realme UI 6.0 based on Android 15; an update-duration commitment is not stated on the cited specifications page | Six Android OS/One UI upgrades and six years of security updates, according to Samsung’s India launch announcement |
These are manufacturer-published specifications and commitments, not independent test results. The cited sources do not establish real-world battery life, charge time, camera quality or a performance winner. Sources: realme P4 5G specifications, realme P4 5G product page, Samsung Galaxy A27 5G purchase page, and Samsung Newsroom India launch announcement.
Display: 144Hz on realme, 120Hz on Samsung
realme lists a slightly larger 6.77-inch display with a maximum refresh rate of 144Hz; Samsung lists a 6.7-inch display with a maximum of 120Hz. A higher refresh-rate specification may appeal if smooth scrolling and motion are priorities, but the numbers alone do not show how the displays look or perform in everyday use. The manufacturers also use different panel names—AMOLED for realme and Super AMOLED for Samsung—so those labels are not a like-for-like quality test.

The P4’s listed typical battery capacity is 7,000mAh, compared with 5,000mAh for the A27. realme specifies 80W charging and says the charging adapter is included in the box. Samsung’s purchase page says a travel adapter is not included. Battery capacity does not establish actual runtime, and the available specifications do not establish either phone’s charge time under comparable conditions.

Cameras: Samsung lists OIS; megapixels do not settle image quality
realme specifies a 50MP main camera and an 8MP wide-angle camera. Samsung lists 50MP, 5MP and 2MP rear cameras, and its sources identify OIS on the rear camera. OIS is a concrete hardware distinction, but neither camera count nor megapixel resolution proves which phone takes better photos. The listed front-camera resolutions are 16MP for realme and 12MP for Samsung; those numbers alone do not establish selfie quality.
Software support and performance
Samsung’s stated update commitment
Samsung’s India launch announcement promises six Android OS/One UI upgrades and six years of security updates for the Galaxy A27 5G. The cited realme specifications page identifies Android 15-based realme UI 6.0 but does not state an update-support duration. On the documented information available here, Samsung has the clearer long-term support commitment.

Processor specifications are not a performance comparison
The listed platforms are MediaTek Dimensity 7400 Ultra for the P4, with realme also promoting a dedicated graphics chip, and Snapdragon 6 Gen 3 for the A27 according to Samsung’s launch announcement. These names do not establish which phone is faster in use. A fair performance verdict would require comparable testing of the actual phones and software versions; the cited sources do not provide that evidence.
