The Redmi Note 15 5G arrives as a confident mid range smartphone that feels far more considered than its price suggests. Xiaomi has spent years refining the Note series and this model shows a brand comfortable with its strengths. It is not chasing gimmicks or headline grabbing specs for the sake of it. Instead, it focuses on balance, practicality, and day to day usability.
The first thing that strikes you is how slim and light the phone feels. At just 7.35mm thick, it slips easily into a pocket and never feels cumbersome in the hand. Even with the supplied protective case fitted, it remains impressively manageable. The dual curved front and back help here, creating a shape that feels smooth and natural to hold over long periods. It looks smart too. The camera housing is familiar territory for recent Redmi devices and while it does protrude slightly, it never became uncomfortable or distracting during use.

Battery life is one of the Note 15 5G's strongest selling points. The 5520mAh silicon carbon battery comfortably lasts through heavy daily use, often pushing into a second day without anxiety. Xiaomi claims up to 1.58 days of endurance and that feels realistic rather than optimistic. Video playback figures of around 21 hours stack up well in real world testing. When it does need topping up, 45W turbo charging gets you back on your feet quickly. The inclusion of 18W reverse charging is a genuinely useful extra, especially if you ever find yourself rescuing a friend's dying phone.
Durability is another quiet strength. The display glass is rated to survive face down drops from 1.7 metres, and the aluminium alloy mid frame gives the whole device a reassuring rigidity. Add IP65 dust and water resistance and this is a phone that feels built for everyday life rather than careful handling. Wet Touch Technology 2.0 works exactly as advertised, keeping the screen responsive even with damp fingers or in light rain.
The 6.77 inch AMOLED display is a highlight. Full HD plus resolution keeps everything sharp, while peak brightness of up to 3200 nits makes outdoor use a non issue. PWM dimming at 3840Hz helps reduce eye strain during long viewing sessions, which is easy to appreciate after an evening of scrolling or streaming. Dual speakers with 300 percent volume boost give audio real presence, making this a solid device for video and casual gaming.

Performance is handled by the Snapdragon 6 Gen 3 chipset, which keeps the phone feeling brisk and responsive. Apps open quickly, multitasking is smooth, and everyday navigation never feels laboured. It is not aimed at power users chasing flagship benchmarks, but for a mid range device it strikes the right balance between speed and efficiency.
Photography is where the Redmi Note 15 5G really separates itself from cheaper models. The 108MP main camera now includes optical image stabilisation, which makes a noticeable difference in low light shots and video. Detail is excellent, though the large file sizes mean you may want to drop the resolution for everyday snaps. This is the first model in the standard lineup to add an ultra wide camera, giving genuine versatility without stepping up to a Pro device. The 20MP front camera performs well for video calls and selfies, while AI features such as reflection removal and object erasing are useful without feeling overbearing.

There are compromises, and they are worth acknowledging. The lack of a 3.5mm headphone socket will disappoint anyone who still prefers wired audio, particularly when connecting to older non Bluetooth equipment. Storage expansion is also a familiar frustration. You can use a second SIM or a memory card, but not both at the same time. These are not deal breakers, but they are worth bearing in mind depending on how you use your phone.
Taken as a whole, the Redmi Note 15 5G feels like a well judged mid range smartphone rather than a flashy one. At around £199, it delivers strong battery life, a capable camera system, solid performance, and a design that feels more premium than expected. Xiaomi continues to cement its reputation for offering good quality phones across every price bracket, and this model sits comfortably among its best value efforts.
If you are shopping for a reliable, modern replacement without paying flagship money, the Redmi Note 15 5G deserves a serious look. It does exactly what you expect, and in a few areas, it does rather more.
I score the Redmi Note 15 5G a solid 8.5 out of 10.
