Thank you for your support of Xiaomi products. The mobile phone goes through strict professional inspection before leaving the factory, so you can use it with confidence. The REDMI A3 undergoes features a high-brightness 90Hz refresh rate screen, which delivers a superior visual experience. However, the high brightness 90Hz mode can result in increased power consumption.
To mitigate this, the software is set to default automatic brightness adjustment and a 60Hz refresh rate to effectively reduce power usage. If you want to conserve power, you can activate power-saving mode, lower the screen brightness and refresh rate, and close background applications.
