Redmi 15 5G review: A phablet-sized battery beast with budget DNA

In an era dominated by sleek foldables and compact flagships, the Redmi 15 5G stands out with its nostalgic, oversized design reminiscent of early 2010s smartphones. Boasting a substantial 6.9-inch display and a hefty 7,000mAh battery, it prompts an intriguing question: Is bigger truly better in the budget smartphone landscape of 2025? The Redmi 15 makes an unforgettable first impression due to its massive size. Its 6.9-inch LCD display resembles a compact tablet more than a traditional smartphone, catering specifically to binge-watchers and avid content consumers. The Full HD+ panel, featuring a peak refresh rate of 144Hz, offers vibrant colors and adequate brightness for outdoor use, although the thick bezels may feel outdated. While not a dealbreaker for those seeking an immersive viewing experience, they do detract from a more premium appearance. The speaker system impresses with what Xiaomi claims is "200% volume," though the mono speaker can be muffled if covered during use. Surprisingly, the build quality and design of the Redmi 15 defy its budget label. The Frosted White finish provides a solid feel with a marble-like texture for added grip. The metal camera frame enhances its overall aesthetic, making it look like a device costing twice as much. Priced under ₹15,000, the phone also features an IP64 rating, a side-mounted fingerprint sensor, and an IR blaster, rounding out a commendable hardware package. The 7,000mAh battery is undoubtedly the highlight, delivering two full days of moderate use, including calls, messaging, video streaming, and light gaming. Even heavy users will find it lasts a full day without needing to recharge. When it’s time to connect the charger, the 33W charger can fully charge the device in just over 80 minutes, with 18W reverse charging available for topping up accessories like earbuds. Under the hood, the Redmi 15 is powered by the Snapdragon 6s Gen 3 processor. While it may not top benchmark charts, it performs adequately for everyday tasks such as social media browsing and video playback, with minimal stuttering. However, gaming can be a mixed bag; popular titles like BGMI and Call of Duty Mobile may experience occasional frame drops under heavy load. Notably, the device manages heat well, remaining cool even during extended gaming sessions. In terms of photography, the dual rear camera setup includes a 50MP primary sensor that performs well in daylight, producing crisp and colorful images. Portraits are satisfactory, although low-light photography reveals noticeable noise and an overexposed night mode. For casual photography users, the results are decent, but enthusiasts may want to explore better options. Running on HyperOS 2.0 based on Android 15, the software experience is relatively clean, though the presence of over 60 pre-installed apps can be overwhelming during setup. On the bright side, Xiaomi promises two major OS upgrades and four years of security updates, exceeding many competitors' offerings. HyperOS introduces some engaging AI features like Circle to Search and AI sky editing, which, while entertaining, likely won’t influence your purchasing decision. In conclusion, the Redmi 15 5G prioritizes what many users truly seek: a large screen and a robust battery. For those who prioritize streaming, scrolling, and video calling over gaming or photography, this device offers exceptional value at ₹13,999. While it may lack sleekness and compactness, it excels in delivering essential features for everyday use.
