Testing how well the Redmi 15 performs under gaming pressure

The Redmi 15 has been launched with impressive specs for a budget device, but gamers are curious to know whether it can handle demanding titles like PUBG Mobile, Genshin Impact, or Call of Duty: Mobile. With a Snapdragon 6s Gen 3 processor, a 144Hz display, and a 7000 mAh battery, it certainly looks capable on paper — but real-world performance tells the full story.

During testing, the Redmi 15 handled popular titles like BGMI and COD Mobile comfortably at medium to high settings. Frame rates hovered around 50–55 FPS on balanced graphics, which is respectable for its segment. Gameplay felt smooth in lighter titles such as Asphalt 9, Free Fire, and Mobile Legends, while heavier games required some compromises in resolution or effects to maintain consistency.

The large 6.9-inch Full HD+ display plays a key role in enhancing gaming immersion. Its 144Hz refresh rate makes motion look fluid, although not every game fully supports this refresh rate. Still, the touch response is accurate, and input lag remains low, giving players solid control during fast-paced sessions.

Thermal management is one of the Redmi 15’s strongest points. Even after extended play sessions of up to 90 minutes, the phone stayed comfortably warm rather than hot. Xiaomi’s cooling design keeps the chipset from throttling too aggressively, ensuring stable frame rates for longer periods. This makes it ideal for casual or mid-level gamers who play for hours at a stretch.

Battery life also stands out in gaming. The 7000 mAh capacity allows nearly two full days of moderate use or 6–7 hours of continuous gaming. Even heavy sessions don’t drain it too quickly, and with 33W charging support, topping up the battery takes just over an hour. This endurance gives the Redmi 15 an edge over most mid-range competitors.

However, it’s not without limits. Games like Genshin Impact and Fortnite, which demand high GPU power, push the Snapdragon 6s Gen 3 near its limits. Frame rates can dip below 30 FPS at max settings, and occasional stutters appear during intense scenes. For smoother performance, it’s best to play such games at medium settings.

The 8GB RAM variant delivers a noticeably better experience than the 4GB model. Loading times are shorter, background apps stay active, and performance remains steadier when multitasking. Players planning to game regularly should definitely opt for the higher-memory version.

Audio and haptics further enhance gameplay. The dual speakers produce strong, balanced sound, and the vibration feedback feels precise during shooting or racing games. Combined with the big display, this gives a surprisingly premium feel despite its budget positioning.

Overall, the Redmi 15 isn’t a dedicated gaming beast, but it’s far from weak. It delivers reliable gaming performance for popular titles, maintains cool temperatures, and offers outstanding battery life. For its price, it strikes a great balance between entertainment, performance, and endurance — proving that even budget phones can play with the big names when tuned right.
