Smartphones are getting more and more powerful, but the battery capacity is lagging behind. That’s the reason why nowadays some OEMs (e.g. Nokia, Xiaomi, Vivo, Samsung or Huawei, etc.) are killing background applications without users’ consent, and they call it “optimization”. To avoid the background app termination you need to follow these steps for each manufacturer of Android OS. Note that instructions for different manufacturers or different versions of customized Android firmwares are mostly very similar.
