Xiaomi launches limited-time 20% off battery replacement program for 67 devices

It is a familiar frustration: as smartphone batteries inevitably degrade , the temptation to purchase a brand-new device grows. Yet, a simple battery swap remains one of the most practical ways to breathe new life into an aging phone. Recognizing this, Xiaomi has rolled out its May Service Week in China , running through May 7th , offering users significantly discounted battery replacements .

During this limited-time event , pricing for a fresh battery starts at just 47.2 yuan (approximately $7) , reflecting a generous 20% discount. What truly sets this initiative apart is its impressive scope, with the promotion covering a massive roster of 67 different smartphone models across multiple generations .

The eligibility list is remarkably comprehensive . It supports older favorites like the Xiaomi 10 Pro right up through the 11, 12, 13, and 14 lineups, all the way to the newly launched Xiaomi 15 series . Premium devices are also included , with support extending to the Mix 4, Mix Fold models, and the Mix Flip, alongside key Redmi lineups.

On the Redmi side , the promotion covers the immensely popular Note family (spanning the Redmi Note 10, 11, 12, 13, and 14 series), the performance-driven K series (K40, K50, K60, and K70), and the Redmi Turbo line . Even budget-friendly models from the broader number series , such as the Redmi 14C, qualify for the discount.

These recurring service weeks have become a highly anticipated staple for Xiaomi users . By providing an affordable maintenance avenue , the tech giant actively encourages consumers to keep perfectly functional hardware in circulation rather than resorting to an expensive, premature upgrade .

Alongside the discount, Xiaomi offered some practical perspective on device maintenance . The company emphasized that gradual degradation—where a battery loses capacity over hundreds of charge cycles —is entirely normal behavior. Rather than stressing over typical wear and tear, users are advised to simply swap out the battery once it no longer sustains their daily routine .

However, Xiaomi cautioned that abnormal wear stemming from physical impact , extreme temperatures , or erratic charging habits should be addressed immediately. To maximize a battery’s lifespan, the manufacturer recommends steering clear of extreme heat or cold and sticking to consistent, standard charging routines .
