I’m with you on how horrible the 15PM battery is. I have a launch day device with 336 cycles and at 88% battery capacity. I’m not upgrading this year, and I’m now running this battery into the ground to hit 79% to get a battery replacement.
15 Pro, first use Oct 2023, 113 cycles, 100% health
Have lived in an area with good reception and thus great battery life. I got by with the 80% charging limit there, charging once a day in the morning. Now live in an area with poor reception and the battery drains much faster. Using optimized charging now on a 5W charger. Never let the phone sit at either end of the charge to limit crystallization at the anode and cathode, which degrades the battery.

Here are my stats. Since I bought the 15Pro Max I have used a Belkin Boost Charge Pro every night and charge to 80%.
Just noticed that my launch day 15PM dropped to 97% at 206 cycles, after hanging at 99% for a few months.
I'm just not addicted to social media.
gets me thru the day just fine with normal activity, text messages, a few calls etc.
551 cycles! the phone's only been out 332 days lol

Interesting I’ve turned off all charge limits and I’m higher. Always fast charge too!
15PM (launch day)
87% Max Capacity
374 Cycles
80% Charge Limit.
Thermal issues and battery degradation have been simply terrible.

you are! I don't have any charge limits on either. I fast charge as well. I'm convinced part of the reason for me is magsafe chargers - I have one from Belkin and one from Mophie. I use these at home and there's always a lot of heat. I also have a magnetic Anker charger but I use that rarely. There's a ton of heat from that too. But the convenience of those outweigh having to change habits.
