Realme 15 5G VS Samsung Galaxy F36 5G

In terms of physical form, both phones occupy a similar space — large, slim slabs that fit the modern smartphone mold. The Realme 15 5G is marginally more compact at 162.3 × 76.2 × 7.66 mm versus the Samsung Galaxy F36 5G's 164.4 × 77.9 × 7.7 mm, and at 187 g it is a meaningful 10 g lighter than the F36 5G's 197 g. While neither difference is dramatic in isolation, together they make the Realme noticeably easier to handle during one-handed use or extended sessions.

The most consequential design distinction, however, is water resistance. The Realme 15 5G carries a waterproof rating, while the Samsung Galaxy F36 5G offers none. In practical terms, this means the Realme can survive rain, splashes, or an accidental drop near a sink without concern, whereas the F36 5G offers no such protection. For users who are active outdoors or simply want peace of mind in everyday situations, this is a significant real-world advantage — one that is often reserved for more premium devices.

Neither phone features a rugged build or a foldable form factor, so those are non-factors here. Overall, the Realme 15 5G holds a clear design edge: it is lighter, slightly more compact, and critically, it adds water resistance that the Samsung Galaxy F36 5G entirely lacks.

Both phones use OLED/AMOLED panels, so the baseline visual quality — deep blacks, vibrant colors, strong contrast — is shared. The differences emerge in the finer details, and they consistently favor the Realme 15 5G. Its 6.8″ screen is slightly larger, but more importantly, its 1280 × 2800 resolution translates to a pixel density of 453 ppi, compared to the F36 5G's 1080 × 2340 at 385 ppi. That 68 ppi gap is perceptible — text appears crisper, fine details in images and video are more defined, and the overall image simply looks sharper on the Realme.

The brightness and refresh rate gaps reinforce this advantage further. At 1800 nits typical brightness, the Realme 15 5G will remain clearly readable in direct sunlight where the F36 5G's 1200 nits may start to struggle. Meanwhile, a 144Hz refresh rate versus 120Hz makes scrolling and animations feel marginally smoother on the Realme — though both are comfortably above the threshold where most users notice a real difference in daily use. The Realme also adds branded damage-resistant glass, a meaningful durability feature the F36 5G does not offer, complementing the water resistance advantage already noted in the design category.

Where the two phones are evenly matched — Always-On Display support, no HDR10+ or Dolby Vision on either — those shared omissions don't change the overall verdict. The Realme 15 5G holds a clear display advantage across sharpness, peak brightness, and screen protection, making it the stronger choice for users who prioritize visual quality and durability.

On paper, the CPU contest looks close — both chips use an 8-core big.LITTLE configuration with nearly identical clock speeds, and their Geekbench 6 scores reflect that: 1026 vs 1007 single-core and 2932 vs 2758 multi-core for the Realme 15 5G and Samsung Galaxy F36 5G respectively. The Realme's MediaTek Dimensity 7300 does edge out the Exynos 1380 in both tests, but the margins are modest enough that everyday tasks — app launches, browsing, streaming — will feel essentially equivalent on either device.

Where the gap becomes far more consequential is in memory and storage. The Realme 15 5G ships with 12GB of RAM running at 6400 MHz, expandable to 16GB, paired with 512GB of internal storage. The F36 5G offers 6GB of RAM at 3200 MHz with a maximum of 8GB and just 128GB of storage. The Realme's RAM is not only double in capacity but also double the speed — faster RAM reduces latency in memory-intensive operations, meaning smoother multitasking, quicker app switching, and better sustained performance under load. The fourfold storage advantage is equally stark for users who store large media libraries or games locally.

The Realme also benefits from a more advanced 4 nm fabrication process versus the F36 5G's 5 nm, which generally translates to better power efficiency at comparable performance levels. Taken together, the Realme 15 5G holds a decisive performance advantage — not because its processor dramatically outpaces the competition, but because its memory configuration and chip efficiency position it as a noticeably more capable and future-proof device overall.

The rear camera systems look similar at a glance — both lead with a 50 MP main sensor backed by an 8 MP secondary, both offer OIS, 4K at 30fps video, phase-detection autofocus, and an identical manual controls toolkit. The Samsung Galaxy F36 5G adds a third 2 MP lens, but a 2 MP depth sensor contributes almost nothing beyond what software portrait algorithms already handle; it should not be treated as a meaningful hardware advantage. More relevant is the Realme 15 5G's BSI (Back-Side Illuminated) sensor, which captures more light per pixel — a genuine benefit in low-light or indoor shooting where the F36 5G's conventional sensor may produce noisier results. The Realme also features a dual-tone, dual-LED flash versus the F36 5G's single LED, which helps produce more natural, color-accurate flash photography.

The starkest difference in this group, however, sits on the front. The Realme 15 5G's 50 MP front camera dwarfs the F36 5G's 13 MP shooter — a nearly fourfold resolution gap that translates directly to sharper, more detailed selfies with greater cropping flexibility. For users who rely heavily on the front camera for video calls, social content, or portraits, this alone is a decisive differentiator.

Both phones share the same video ceiling, autofocus behavior, and creative shooting modes, so those are non-factors. On the rear, the Realme's BSI sensor and superior flash give it a subtle but real edge in image quality. Combined with its dominant front camera, the Realme 15 5G wins this category clearly, particularly for selfie-focused users.

This is a rare category where the data tells a straightforward story: the Realme 15 5G and Samsung Galaxy F36 5G are running an identical software feature set across every single spec provided. Both launch on Android 15, both carry the same privacy toolkit — location controls, camera and microphone permissions, clipboard warnings, app tracking blockers — and both support the same productivity and usability features including split-screen multitasking, Picture-in-Picture, dynamic theming, widgets, and on-device machine learning.

Notably, neither phone receives direct OS updates from Google, meaning both rely on their respective manufacturers to push Android updates. Neither supports Wi-Fi password sharing or focus modes, and neither can be used as a PC. These shared omissions apply equally and do not differentiate either device.

With no divergence across any spec in this group, the verdict here is an unambiguous tie. A user's software experience will be shaped entirely by each manufacturer's custom Android skin rather than by any underlying OS-level feature gap — a factor that falls outside the scope of the data provided.

Few spec comparisons are this one-sided. The Realme 15 5G packs a 7000 mAh battery against the Samsung Galaxy F36 5G's 5000 mAh — a 40% larger capacity that, in practical terms, is the difference between a phone that comfortably lasts two days of moderate use and one that typically needs a nightly charge. For heavy users, commuters, or anyone who spends long stretches away from an outlet, that extra 2000 mAh is not a marginal gain; it is a fundamentally different usage experience.

The charging story is equally lopsided. The Realme's 80W fast charging is more than three times faster than the F36 5G's 25W. In real-world terms, this means the Realme can recover a significant portion of its — already much larger — battery in the time it takes the Samsung to make a modest dent. When you do need to plug in, the Realme gets you back to full and out the door far more quickly.

Both phones share the same structural limitations — no wireless charging, no reverse wireless charging, non-removable batteries, and both include a charger in the box — so those factors are a wash. On every metric that actually determines battery experience, the Realme 15 5G wins this category decisively, offering substantially more endurance and dramatically faster replenishment.

The audio specs for these two phones are completely identical across every data point provided. Both feature stereo speakers and both omit a 3.5 mm headphone jack, meaning wired audio requires a USB-C adapter on either device. Neither supports any high-resolution Bluetooth codec — no aptX, no LDAC, no aptX HD or Adaptive variants — so wireless listening is limited to standard Bluetooth audio quality on both.

This is a straightforward tie. There is no differentiating factor in this group, and neither phone holds any audio hardware advantage over the other based on the available data.

The connectivity picture here is genuinely split, with each phone holding meaningful advantages the other lacks. The Samsung Galaxy F36 5G brings two features that will matter to a broad range of users: NFC and an external memory slot. NFC enables contactless payments and quick device pairing — an increasingly expected feature that the Realme 15 5G simply does not offer. The expandable storage is equally practical; given that the F36 5G ships with only 128GB internally, the ability to add a microSD card is less a bonus and more a necessity for many users.

The Realme 15 5G counters with a notably stronger upload speed — 3270 Mbits/s versus the F36 5G's 1280 Mbits/s — which benefits users who frequently transfer large files, upload video content, or rely on cloud backups over cellular. It also carries a slightly newer Bluetooth 5.4 versus 5.3, though the practical difference between these two versions in everyday use is negligible. The F36 5G's higher rated download speed of 3790 Mbits/s against the Realme's 3270 Mbits/s is similarly unlikely to be felt in real-world conditions where network infrastructure is typically the bottleneck.

Both phones support 5G, dual SIM, Wi-Fi 6, USB-C, GPS, and a fingerprint scanner, so the core connectivity foundation is identical. Ultimately, which phone ″wins″ this category depends on use case: the F36 5G has a practical edge for most consumers thanks to NFC and expandable storage, while the Realme holds an advantage specifically for users with heavy upload demands. For the majority, the Samsung's feature additions are more universally useful day-to-day.

The miscellaneous specs for both phones are identical across every available data point. Both include a video light, and neither features sapphire glass, a curved display, or an e-paper screen — none of which are realistic expectations at this market segment anyway. This is a clear tie, with no differentiating factor present in the provided data.
