Battery (required on duty)
This is the #1 Android miss for riders.
- Open phone Settings → Apps → Koolodoor → Battery (wording varies by brand).
- Set battery usage to Unrestricted (not Optimized / Restricted).
- Samsung: also check Device care → Battery → Background usage limits — remove Koolodoor from sleeping / deep-sleeping apps.
Quick heads up
If battery is Optimized, Fleet duty location and offer pings can stop when the screen is off.
