Weekly alarms and snooze but excessive battery use

One of the few weekly alarms I have found that supports snooze.
The iPhone battery usage says in 24 hrs it is burning almost as much as Waze driving app in foreground for 1 hr. That is after going into settings and disallowing it to use Location Service. (It by default turns on GPS to give weather predictions.) But I expect it to use almost nothing! Maybe iOS measurement is wrong?
