For background on how these settings could relate to the performance of the Zenit app, Battery Optimization

Huawei has its own unique take on Android that it calls EMUI, so there may be some settings you can adjust to ensure Zenit isn’t affected by aggressive optimization.

• Settings > Advanced Settings > Battery Manager > Power plan is set to Performance.
• Settings > Advanced Settings > Battery Manager > Protected apps – check for Zenit to be Protected.
• Settings > Apps > Zenit > Battery > Power-intensive prompt [x] and Keep running after screen off [x].
• Settings > Apps > Advanced (at the bottom) > Ignore optimizations > Tap Allowed > All apps > Find Zenit on the list and set to Allow.

Some Huawei models have a slightly different location for some settings:

Huawei P9 Plus:

• Settings > Apps > Settings > Special access > Ignore battery optimization > select Allow for Zenit.

Huawei P20 and Huawei Honor 9 Lite:

• Settings > Battery > App launch and then set Zenit app to “Manage manually” and make sure everything is turned on.
