I bought my 12 Pro Max at launch last year. I'm currently at 95% battery health and I'm thinking that's kind of not the norm since I've seen lots of other 12 Pro Max owners stating they're still in the 98% to 100% with their phones. I normally never let my battery run below 20% but I do charge it overnight to 100% every night.

Is charging my battery to 100% on a daily basis a bad thing?

Also, please state what your 12 Pro Max battery health is along with when you bought your phone.
 
I’m at 94%. Received on 11/22/20. I was at 100% for like 6 months. No wireless charging.
 
Launch day. 5w wired charging only

Mine was 89% a month ago before I got the device replaced for an accidental damage claim. It was also getting really hot in extremely light use (not in sunlight, not charging, etc). There are a few threads on this and I’m pretty sure there’s a real quality issue with the 12 series batteries
 
92%. Launch day. Mainly wireless charging with some wired charging when I forget to charge it and need it to charge faster
 
Batteryhealth shows 98%, but in coconutbattery shows 99%.

Same here. Mine is at 100% currently because I had it replaced a couple of months ago due to overheating. However this new replacement seems to be getting warm again with some basic activity. Even watching YouTube it warmed up quite a bit which is not supposed to happen. I have a feeling that this replacement will be going through the same overheating issue soon. Hopefully not though. I have a 13 Pro Max ordered so hopefully it will be better. I’ll still keep my 12 Pro Max as a second camera/iPhone since I love photography

My launch day 12 Pro Max is currently at 100% battery health.
 
Launch day 99% 😅 will be 100% again, once I pickup the 13 pro max 😁😂
 
iPhone 12 Pro Max, got it at launch. Currently at 89% health.

Mostly charging via MagSafe at night, and via lightning in car when driving.
