Same here. But far before the latest update. My Zenfone 8 drained straight from the box when i bought it new. It went to Asus Repair three times. Not even once they were able to 'reproduce' the issue. And simply sensed it back unrepaired. The so called Other Apps drain the phone. Even when nothing else is installed. Also in safe mode the battery drains in no time. No energy saving setting or anything else will prevent this. Stand by alone kills the battery within hours sometimes.
Also here on ZenTalk Asus doesn't get much further then suggestions of restarting your phone, reset it, taking screen shots of the drain (?) or use their logging tool. Save yourself the hassle. Nothing will matter. The phone will keep draining and Asus won't be able to fix it for you. Or they won't. You bought an inferior product with an inferior service. Sad, but true.
