To improve performance, the system only runs two accounts in the background: the owner"s
account and the previous sub-user"s account. All other user accounts are suspended. Alarms set
by these accounts will not go off.
Solution:
Log back in to the sub-user account that was used to set the alarm: Go to Settings > Users &
accounts > Users and select the desired sub-user.
If the issue persists, perform the following steps:
EMUI 4.X and EMUI 5.X: Go to Settings > Apps > Clock > Storage > CLEAR DATA.
EMUI 8.0: Go to Settings > Apps & notifications > Apps > Clock > Storage > CLEAR DATA.

and disable Power saving mode.
Power saving mode is also disabled automatically when your phone is charging.
