My 15pm is at 90%, cycle count is 245I've used my 15 Pro Max for a year now and I'm at 99% battery health. Granted, I'm a very low user since I much prefer using my iPad, so I only have 77 charging cycles on mine. I also only charge to 80%. I did not upgrade this year for the first time in a long time.
Only time is gets low is at one of the WDW parks or on vacation when I take tons of videos/photos or with very intermittent WiFi connections.
