So I went to Apple. Real Apple store in Seoul -- Flagship store. Aussie(?) GM. He wouldn't even humor this issue. Went to get the battery swapped out. Battery issue (https://discussions.apple.com/thread/251211985?page=35) and (https://discussions.apple.com/thread/251265543?page=14) Said diagnostics said there was no problem. Told them that I don't care what their diags say because I have clear screenshots of the issue and they could see the linear battery drain in the Settings app. They said "we don't have time to replace your battery because we need to close" (it was about 2 hours away from closing and I waiting already an hour and a half -- in a small glass corner (felt like a prison) because of the COVID-19 distancing (okay, whatever I get it -- even though the rest of Seoul isn't handling it like that) Waited in my glass box in a corner and was told that I would be left without a phone (no loner phone given like they have done for 13 years) if I wanted a battery. I said no way, I need to have communication and I have a life outside of coming to the Apple store. Also had AirPods problem and said I wanted that fixed too and they said "Nope, one appt, one piece of hardware". I was ******. So they said I could go back the next day so I said "if I come back tomorrow, then I want my AirPods addressed too". They said nope, come back next week. Guy leaves for 20 mins... I'm sitting there literally banging my head against the glass box they have me in and he comes with a small box and says he will swap out the entire iPhone. While that's great, I didn't want a new iPhone or ask for it. I also had a very expensive tempered glass (NOT film) screen cover which they said "well you lose that and we aren't giving you a new one". I asked to speak to someone about the screen. Really nice Korean girl came over and empathized with me. I told her everything and had all my problems (written in Korean by myself) on my Notes app (BUT THEY TOOK MY IPHONE AND WIPED IT) so I had to explain it all out loud. Asked to speak to manager. Aussie manager comes over and was (pretend) polite at first but had this tone of voice that was so mocking. He said I was "making it out to be a bad thing" that I got a new iPhone instead of a battery when he is "shocked" that his employees even did that "because it costs the company money". I said that I understood that but I asked simply for a new battery and that was it and they would not do that which is beyond comprehension. I told him about the Airpods clicking noise (https://discussions.apple.com/thread/251050158) and how many people have it and he said that is a "small number" and that the Apple Communities are quote "an echo chamber" calling all of us crazy and that we are just repeating what other say "for the **** of it". I said, nope, these probs are all over Reddit, etc. He says "that is his front page and he reads it all the time". Anyway, my APPs have been replaced for this clicking sound (and battery issues) a few times. He looked up the records and starts being suspicious of me. "it's not normal to have this many swap-outs unless it's really bad luck". I have AppleCare+ and don't care if it takes 100 swap-outs to get a working piece of hardware -- I paid for the warranty and it comes with a 1 year warranty either way - PERIOD. He refused to put the AirPods in his ears saying "I'm not putting those in my ears" and then wrote on the log "could not reproduce -- swapping out as one time exception" HOW DO YOU REPRODUCE THE ISSUE IF YOU WON'T LISTEN TO THE PROBLEM BY PUTTING THE HARDWARE (AIRPODS) IN YOUR EARS TO LISTEN TO IT? Then the first Korean male employee who serviced me says in English to the Aussie manager that my Airpods are water damaged. WHAT? NO. They are NOT. He said "maybe it's sweat". I said that they are IPX4 and a bit of sweat is expected INSIDE YOUR EAR". But this was it for the Aussie manager. He had this tone saying Ohhhhhh. Well!!! that changes a lot now doesn't it????. I just said, in a monotone voice -- Look at it yourself. There is no water damage. If there is sweat, it's designed for that. He didn't mention anything about it being damaged after looking himself. This new right APP still has the clicking sound (couldn't hear it in the loud Apple Store) and I think they are just bugged this way altogether. But the attitude had me so livid so I think I have made my choice to switch to the competition (as now I have a still-shrink-wrapped iPhone XS Max that I can sell for even more money -- not my choice, Apple's choice) and even this NEW iPhone STILL has horrible battery -- no different than the other one. So Apple won't admit its mistakes, degraded me in front of other employees (the one nice Korean female felt SO bad for me, I could see it in her eyes), and said that all of us on this forum are liars and just this is an "echo chamber" (all quotes) so I'm done. I'm over it. 13 years of iPhone and I don't deserve this treatment. So keeping on topic, there is no fix to this battery problem apparently. It's software. Brand new XS Max exhibits the same thing as soon as I restored it to 13.5.1. And the customer service was abysmal. I'll keep the APPs but still may seek out a new right one if I can get this clicking to stop.
