Screen jumping or unresponsive touchscreen behavior while charging is often caused by electrical interference that can affect the phone's touch sensitivity.
There are a few factors that can contribute to this issue:
1. When using non-original or third-party chargers, they can not provide the same stable power output as the provided charger, which can introduce electrical noise or fluctuations. This noise can disrupt the phone's touchscreen performance, causing abnormal behavior, such as screen jumping or unresponsiveness.
2. Charging your device in areas with a lot of electrical interference, such as near high-speed trains, train stations, or large industrial power plants, can also introduce significant noise into the charging process. This interference can have an impact on the phone's internal electronics, leading to disturbances in how the touchscreen reacts.
To avoid this issue, we recommend using the provided charger that is designed specifically for the Xiaomi 15 Ultra, as it is optimized to deliver stable power to your device without causing interference. Additionally, if you're experiencing screen jumping in a particular environment, try charging in a different power grid environment, away from sources of electrical noise, to see if the issue persists.
