Hello,

I'm looking for an app that can record cpu usage and can show how much each installed app used at a specific time. Anyone knows if such app exists?

Since there may be other ways to solve my problem, I'll try to explain why I need that app.

Every 3 hours (3:00, 6:00, 9:00, 12:00,...), for about 30 seconds, my phone gets really laggy or completely unresponsive. So I guess it must be an app that's using too many resources, but I can't figure out which one it is. It started happening about 2 weeks ago.

OS: Android 7.1.2, custom ROM

Thank you for your answer. I tried what you suggested. It only shows Screen under "Use since last full charge". I also disabled both wifi and mobile data, so apps won't use power trying to update. I don't think it shows apps if the power used is less than 1%.
