I am also investigating the cause of high cpu load leading to high battery consumption on my XA2. One thing i can confirm: Stoping android support is great. I realized that there are android apps in the background I have not started and it’s forbidden for every app on my phone to start background services. So stopping alien dalvik is the key. Another problem I observed is bluetooth. After using wireless headphones and disabling bluetooth there is still load on the cpu. After enabling bluetooth starting and stopping search for devices and stopping bluetooth again the load disappears. I am not sure and have no logs for this but this helps in my case.
