robin143, Jun 16, 2019 : In order to improve battery life, I tried using background app restriction , background data disabled and data saver mode. It is identified that the apps keep working in the background while both modes ON position because I can receive app notifications which also include online notifications. (All apps closed in recent apps) . This issue is persisting from the day of purchasing my one plus 6. Why this happening? What is the actual purpose of these two modes i) background app restriction ii) data saver mode.
