Using ATM 10.3.3 Beta 1 on my iPhone 6S Plus which is completely new. Charged 2 times Battery life time is not as good as expected. WhatsApp background activity as you can see on the pictures. Not only one push, background sync is enabled. Absolutely nothing! Clean fresh install with some apps that are all up to date. What can I do against this WhatsApp activity by not deleting the app?
