Which phone is faster?
The GT 7T has the more capable hardware on paper: its Dimensity 8400-MAX is paired with LPDDR5X memory and UFS 4.0 storage. The 15T uses the Dimensity 6400 Max and LPDDR4X memory. That makes the GT 7T the more suitable specification-led pick for demanding games, multitasking and heavier use, but these component differences are not a substitute for independent benchmark or game testing.
How do the displays differ?
Both phones list a 120Hz maximum refresh rate, but the GT 7T has the larger and higher-resolution screen: 6.8 inches at 1280 × 2800, compared with the 15T’s 6.57-inch AMOLED panel at 1080 × 2372. realme says the GT 7T display can reach a local peak of 6,000 nits under 100,000 lux in its lab test. That is a conditional local-peak claim, not a typical full-screen brightness measurement. The 15T specifications list 1,400 nits HBM and 4,000 nits peak.
#1 Best Overall
Battery capacity and charging speed
Each model lists a 7,000mAh typical battery. realme gives the GT 7T a 6,850mAh rated value and the 15T a 6,830mAh minimum value; these are different labels, so they should not be treated as identical measures. The GT 7T supports 120W charging, while the 15T supports 60W and lists an 80W adapter in the box. Capacity and charging specifications alone do not show which phone lasts longer in everyday use.
Camera differences
The 15T lists a 50MP main rear camera, a 2MP monochrome portrait camera and a 50MP front camera. Smartprix lists the GT 7T with a 50MP main and 8MP ultrawide rear camera, while realme advertises 4K at 60fps recording on both the GT 7T’s front and rear cameras. Megapixel counts and supported video modes do not establish which phone takes better photos or video; a direct sample comparison would be needed to judge image quality.

Which one should you buy?
| If your priority is… | Better on-paper fit | Reason |
|---|---|---|
| Gaming, multitasking or faster charging | realme GT 7T | Dimensity 8400-MAX, LPDDR5X, UFS 4.0 and 120W charging |
| A lighter phone with a smaller display | realme 15T 5G | Approximately 181–183g and a 6.57-inch screen |
| Higher listed selfie-camera resolution | realme 15T 5G | Its official specifications list a 50MP front camera |
| Larger, sharper display | realme GT 7T | 6.8-inch, 1280 × 2800 versus 6.57-inch, 1080 × 2372 |
| Lower price in the cited comparison | realme 15T 5G | Smartprix’s dated listing was ₹3,999 lower; verify today’s price and configuration |
At similar current prices, the GT 7T is the stronger specification choice if you value processing headroom, screen resolution and charging speed. The 15T makes more sense if you prefer a lighter, smaller phone or its listed selfie-camera resolution, especially when its current price is lower. Neither recommendation establishes a camera or battery-life winner without direct testing.
