Infinix GT 30 5G VS Realme 15 5G

Both phones share an identical weight of 187 g, so neither has an ergonomic advantage there. In terms of footprint, they are nearly interchangeable — the Realme 15 is marginally shorter and slightly wider, while the Infinix GT 30 is a touch thinner at 8 mm versus 7.66 mm. The real-world difference in hand feel is negligible, though the Realme 15's lower total volume (94.73 cm³ vs 99.27 cm³) reflects a marginally more compact chassis overall.

The most meaningful differentiator in this group is protection rating. The Infinix GT 30 carries an IP64 certification, which means it is dust-protected and can handle water splashes from any direction — fine for rain or accidental spills. The Realme 15, however, is rated IP69, a significantly higher standard that implies full dust-tight sealing and resistance to high-pressure, high-temperature water jets. In practical terms, the Realme 15 can withstand far more aggressive water exposure — submersion-adjacent scenarios and heavy rain — while the GT 30 should be treated with more caution around water.

Neither device has a rugged build or foldable form factor. Overall, the Realme 15 holds a clear edge in this group: its superior IP69 rating is a tangible real-world advantage for durability and longevity, especially for users who are active outdoors or prone to accidental water exposure.

On the surface, these two displays look nearly identical — both are OLED/AMOLED panels at essentially the same size, with matching 144Hz refresh rates, 240Hz touch sampling, identical contrast ratios, and the same HDR and Always-On Display feature set. For everyday smoothness and responsiveness, users of either phone will have a comparable experience.

The sharpness gap is slim but present: the Realme 15 edges ahead with 453 ppi and a 1280 x 2800 px resolution versus the Infinix GT 30's 440 ppi and 1224 x 2720 px. In practice, both exceed the threshold where individual pixels become invisible to the naked eye, so this difference is unlikely to be noticed in daily use. Far more impactful is the brightness disparity — the Realme 15 delivers 1800 nits of typical brightness compared to just 700 nits on the Infinix GT 30. This is not a marginal gap; it translates directly to dramatically better outdoor legibility under direct sunlight, where the GT 30 may struggle while the Realme 15 remains comfortably readable.

The Realme 15 takes a decisive win here. The brightness advantage alone — nearly 2.6× that of the Infinix GT 30 — is a meaningful real-world differentiator for anyone who uses their phone outdoors, and the slightly higher resolution is a modest bonus on top of that.

At the silicon level, these two phones are closer than they might appear — both run on MediaTek 4nm chips with identical GPUs (Mali G615 MC2), matching GPU clock speeds, and the same DDR5 memory architecture. That said, the chipsets themselves diverge in an interesting way: the Infinix GT 30 runs the Dimensity 7400, a newer generation chip with slightly faster peak CPU cores at 2.6 GHz, while the Realme 15 uses the older Dimensity 7300 clocked at 2.5 GHz. The raw CPU advantage belongs to the GT 30, which matters in sustained workloads and processor-bound tasks like gaming or video encoding.

Where the Realme 15 fights back is in memory and storage. Its 12 GB of RAM versus the GT 30's 8 GB gives it a meaningful multitasking edge — more apps stay resident in the background without being killed, and memory-intensive workloads like photo editing or running multiple browser tabs feel more fluid. The storage gap is equally notable: 512 GB on the Realme 15 versus 256 GB on the GT 30 means twice the headroom for media, apps, and offline content without needing to manage space as aggressively.

This group ends in a genuine trade-off. The Infinix GT 30 holds the edge in raw CPU throughput thanks to its newer chipset, making it slightly better suited for peak performance scenarios. The Realme 15 counters with superior RAM and double the storage, which benefits day-to-day versatility and longevity. Users who prioritize gaming performance may lean toward the GT 30, while those who value multitasking headroom and storage capacity will find the Realme 15 more practical.

The rear camera systems pull in opposite directions in meaningful ways. The Infinix GT 30 leads with a 64 MP primary sensor, offering more pixel detail for cropping and post-processing, and it adds laser autofocus for faster, more reliable subject locking — useful in dynamic shooting conditions. It also supports RAW capture, a notable feature for enthusiast photographers who want full control in post-production. The Realme 15, meanwhile, uses a 50 MP main sensor but counters with a BSI (Back-Side Illuminated) sensor design, which improves light gathering efficiency, and crucially adds optical image stabilization (OIS) — something the GT 30 entirely lacks. OIS makes a tangible difference in handheld low-light shots and smooth video footage.

Video recording is another split: the GT 30 can shoot 4K at 60 fps, delivering smoother motion for action content, while the Realme 15 caps out at 4K 30 fps. For videographers, that 60fps ceiling is a genuine advantage. Selfie shooters, however, will find the Realme 15 far more compelling — its front camera is a remarkable 50 MP versus the GT 30's modest 13 MP, a difference that dramatically affects detail and cropping flexibility in selfies and video calls.

Neither phone dominates outright, making this group heavily use-case dependent. The Infinix GT 30 is the stronger choice for video content creators and manual photography enthusiasts, thanks to 4K/60fps, RAW support, and laser AF. The Realme 15 is the better all-rounder for everyday photography — OIS and a BSI sensor improve photo consistency, and its front camera is in a completely different league for selfie-focused users.

This is a rare case of complete feature parity. Every single specification in this group — from the Android 15 base version to privacy controls, productivity tools, and system-level features — is identical across both phones. Neither gains any software advantage over the other based on the provided data.

The shared feature set is, on its own, well-rounded. Both devices offer solid privacy tooling including location controls, camera and microphone permissions, clipboard warnings, and app tracking restrictions. Productivity staples like split-screen multitasking, Picture-in-Picture, widgets, and full-page screenshots are present on both, as are quality-of-life additions such as dynamic theming, an extra dim mode, battery health monitoring, and offline voice recognition. Neither phone receives direct OS updates from Google, meaning both rely on their respective manufacturers for software patches — a consideration for long-term support expectations.

This group is an unambiguous tie. With no differentiating features present in the data, the operating system experience offers no reason to choose one phone over the other, and users should look to other specification groups to inform their decision.

Battery capacity is where the Realme 15 asserts one of its most commanding advantages in this comparison. Its 7000 mAh cell is a substantial 27% larger than the Infinix GT 30's already-respectable 5500 mAh. In practical terms, that gap translates to noticeably extended screen-on time — users who consume media heavily, game frequently, or simply dislike charging daily will find the Realme 15 considerably more accommodating. A 5500 mAh battery is by no means weak, but 7000 mAh pushes into genuine two-day territory for moderate users.

Charging speed further widens the gap in the Realme 15's favor. Its 80W fast charging is nearly double the GT 30's 45W, meaning the Realme 15 not only holds more energy but replenishes it significantly faster — a combination that makes range anxiety largely a non-issue. The one area where the Infinix GT 30 holds an exclusive feature is reverse wireless charging, which allows it to top up accessories like earbuds or a smartwatch wirelessly. The Realme 15 lacks this entirely, so users invested in a wireless charging ecosystem will note the absence.

Overall, the Realme 15 wins this group decisively. The combination of a much larger battery and considerably faster wired charging makes it the stronger choice for endurance-focused users, and the GT 30's reverse wireless charging, while useful, is too niche a feature to offset that two-pronged advantage.

Audio hardware is largely a wash between these two phones. Both drop the 3.5mm headphone jack in favor of wireless-only wired connections, both feature stereo speakers for directional sound during media playback, and neither supports any high-resolution Bluetooth audio codec — no aptX, LDAC, or their variants. Users who prioritize lossless wireless audio through premium headphones will find both phones equally limited in that regard.

The only differentiator in this group is the Infinix GT 30's inclusion of a built-in FM radio, which the Realme 15 lacks entirely. While FM radio is a niche feature for most users, it holds real value in specific scenarios — areas with unreliable internet, emergencies, or simply for users who prefer local broadcast radio without consuming mobile data. It also functions independently of a data connection, which is a meaningful backup in low-connectivity situations.

This group is effectively a near-tie, with a narrow edge to the Infinix GT 30 solely for its FM radio inclusion. For the vast majority of users, the speaker and codec parity means audio experience will be functionally identical day-to-day, but the radio is a genuine exclusive that adds utility for a subset of users.

The connectivity foundations are identical: both phones support 5G, Wi-Fi 6, Bluetooth 5.4, dual SIM, USB Type-C (USB 2.0), and the same suite of motion sensors including GPS, gyroscope, accelerometer, and compass. For most users, this shared baseline means day-to-day wireless performance will be indistinguishable between the two.

The meaningful divergence lies in two exclusive features. The Infinix GT 30 includes NFC, enabling contactless payments, quick Bluetooth pairing, and transit card functionality — a practical, frequently-used feature that the Realme 15 omits entirely. The GT 30 also carries an infrared (IR) blaster, which allows it to function as a universal remote for TVs, air conditioners, and other IR-compatible devices — a convenience the Realme 15 again lacks. Neither of these is a connectivity cornerstone, but NFC in particular has become a daily-use feature for many users in markets where tap-to-pay is widespread.

The Infinix GT 30 takes a clear edge in this group. Holding two exclusive hardware features — NFC and an IR blaster — against none for the Realme 15 makes it the more versatile device from a connectivity and features standpoint, particularly for users who rely on mobile payments or want remote-control functionality built into their phone.

The miscellaneous specification group offers no differentiation whatsoever between these two phones. Both share a video light, and neither features sapphire glass, a curved display, or an e-paper display — every data point is identical.

This group is a complete tie. There is no basis within the provided specs to favour one device over the other here, and users should weigh the more substantive differences found in other specification groups when making their decision.
