In most cases, this is due to 2 root causes:
- A third party app is interfering with your alarms. Usually, these are apps labeled as cleaners/optimizers/boosters such as CCleaner, Clean Master, Greenify, DU Booster, etc. Please make sure to remove/disable these kinds of apps or add Zelda Alarm App to their exceptions rules (if they have one).
- Some Android devices come with battery-saving features which may suspend/kill some apps or disable their background tasks (alarms) in order to save battery life.
Luckily they usually include some sort of whitelist where you can add your apps to prevent this behavior.
We have recently included a notification within the app that warns you about these battery saving options and takes you to the app-whitelist, but in case you want to do it manually here is a list:
- Step 1: settings –> advanced settings –> battery manager –> select the app to protect it.
- Step 2: settings –> apps –> advanced –> ignore battery optimizations, select the app and ignore it.
- Pre-EMUI 5.0 / Android 7 – Go to Settings > “Protected apps”, check your app. Full Instructions
- Tap on the battery icon. Go to Power Management > STAMINA mode > Apps active in standby > Add your app.
- Check your app in the Auto-start Manager.
- Security (App) > Permissions > Autostart – Enable your app
- Settings > Developer Options. Disable “memory optimization”. To enabled Developer Options go to Settings > About. Tap on MIUI 8 times. Full Instructions
- Settings > “Security settings” > “Data saving” and enable your app.
- Go to Settings > Battery > Battery Optimization > Application > Don’t Optimize
