Do you use stamina mode or any kind of battery savers?

Hello @Errazor and welcome to the community!

Has it always been like this with these apps or has it started recently? Have you noticed any pattern as to when this happens? For example, does it happen if you do not use your phone for a longer period? As @alexdon mentioned, are you using the STAMINA-mode or any battery saver apps? Look under Settings > Battery to check if STAMINA mode is enabled.
