no problem, that list will give you some insight on what is draining the battery.

Its the wifi and cell standby, they are eating the battery, and within cell standby its mobile radio active, which is using 40% of battery,  what to do now?

Test the phone in >>> safe mode for several hours and report back.

cell standby draining battery seems like a common problem , if safe mode fixes your problem then its likely that a third party app is causing cell standby to consume so much battery . If not , see if the battery drains fast with airplane mode activated or with SIM card removed if possible , also for wifi i'd recommend that you use stamina mode since it temporarily disables wifi when your not using your phone...
