The Sony Xperia XA may consume more battery in mobile standby mode due to several factors. One possible reason could be background processes and apps running in the background, which can drain the battery even when the phone is not in use. Additionally, if the phone is constantly searching for a network signal or has poor reception, it can lead to increased battery consumption.

Finally, the age and condition of the phone's battery itself can also impact its standby time. **
