title: Android - Manufacturer specific battery saving
body: <p>Im developing a chat app which uses GCM to notify the user of incoming messages. One problem I can't seem to fix is that every manufacturer seems to implement his own battery saving in addition to the doze feature of Android. Most of the time a few apps get automatically put on the whitelist of these phones(like whatsapp). </p>
  
  <p>As example Huawei uses "Protected Apps" and only if the user accepts my Intent which tries to add my App to the protected apps, only then my app works as expected.</p>
  
  <p>Is there any way to get whitelisted or something like that for every manufacturer ? I can't believe I have to buy every phone on the market to test if somebody decided the doze feature is not enough.</p>
  
  <p>Best Regards!</p>
