Redmi Note 15 SE 5G is set to arrive in India this week with a bigger battery and a familiar performance package aimed at heavy users who want an all-day 5G phone.

Xiaomi's Redmi brand will launch the Redmi Note 15 SE 5G in India on 2 April as a special edition in the Note 15 series. The phone will be sold via Flipkart and will be offered in Carbon Black, Crimson Reserve (red) with a vegan leather back, and Frosted White. Redmi says the Crimson Reserve variant is 7.82mm thick, keeping the phone relatively slim despite the larger battery.

The standout change is a 5,800mAh battery, which Redmi claims can deliver more than 44 hours of use on a single charge. This is a step up from the standard Redmi Note 15 5G's 5,520mAh cell, while retaining 45W wired fast charging support. The company is also promising "48-month lag-free performance", suggesting a focus on long-term usability alongside battery endurance.

Under the hood, the Redmi Note 15 SE 5G uses the same Snapdragon 6 Gen 3 chipset as the regular Redmi Note 15 5G, with Redmi claiming up to a 10 percent GPU boost and 30 percent CPU boost over the previous generation. On the back, however, the SE model switches to a dual rear camera in a squircle module, led by a 50-megapixel MasterPixel main sensor capable of recording 4K video. The standard Note 15 5G instead offers a 108-megapixel primary camera paired with an 8-megapixel ultrawide lens, so buyers will trade resolution and an extra lens for the SE's larger battery and refreshed finish.
