Jim: Hello, Ronnie. How can I help you?
Ronnie: Hi! I need some help with my phone.
Jim: Sure thing. What seems to be the matter?
Ronnie: Well, the battery drain is really bad. 
Jim: Can you describe the issue further?
Ronnie: For the first 2 weeks it was fine but now the batter doesn't last for more than 4 hours on full charge.
Jim: OK. Can you send me the battery usage data?
Ronnie: Sure. <file_photo>
Jim: I see you're using antivirus software?
Ronnie: Yeah. Installed it some time ago.
Jim: Have you tried changing its settings?
Ronnie: How?
Jim: Go into Settings, Device maintenance, Apps, Antivirus and settings. Check frequency settings.
Ronnie: It's on high.
Jim: That's probably the issue. Try changing it to lower settings. This should help.
Ronnie: Thank you!
Jim: No problem, you're welcome. Can I assist you any further?
Ronnie: No, thank you.
