Xiaomi has expanded its battery upgrade programme for select older smartphones in China. Instead of limiting larger batteries to newer smartphones, the company is now offering existing users a way to extend the lifespan of their phones with upgraded battery packs. Consequently, Xiaomi 13, Xiaomi 13 Pro, and Xiaomi 13 Ultra users are eligible for higher-capacity battery replacements. The service, however, is not entirely free of cost and incurs a charge, along with limited availability.
