Habpanel slow on wakeup - Android - Fully Desktop Browser

I installed an Android tablet as a wall display. Here Habpanel is displayed with the fully desktop browser. The tablet wakes up when motion is detected. Unfortunately, updating the items takes a long time. Strangely, it takes longer if the tablet has been off for a long time. Often even up to 2 minutes until everything is up to date. If the tablet is woken up regularly, then everything happens very quickly. Do you have an idea?

Thank you!!
