What's your phone’s firmware version (Settings > About phone> Build number)
Are you talking about battery drains in standby mode or in use?
Sorry, we're afraid we may need information on your battery problem.
Could you describe more clearly? Thank you!
I have the same issue. Battery drain is quite strong in the latest current firmware (.70). Hopefully, Asus is already looking into it because the main feature of Max Pro M2 is its battery capacity. Currently using a Galaxy S8+ for now, while waiting for the next fix. Oh! and our Asus phone still doesn't have a Sept security update while old Samsung phones already has it.
