Invest in a cheap audio recorder and leave it running when you notice them acting up. Or, if they do it in response to you making noise, intentionally make some (mundane, reasonable) noise and catch the response.

If the landlord wouldn’t believe it when you tell them the tenants are acting obnoxiously, then there’s no way to phrase that differently to make them take it seriously without giving them some evidence of it.

I’ve switched over to mostly wireless charging, but have to say I’m not completely convinced of it yet. I switched phones in part because my old phone’s battery started having issues and the charging port became loose. I want to prevent that happening on my new phone for as long as I can, so I’m using wireless charging for the most part.

Though wired charging is still so much faster and more efficient. If I really need a charge, or I’m in a hurry, I plug the phone in to charge. I just try to be in the habit of setting my phone on the charging pad when I get home from work.
