Inspired from the 55Wh thread, I’m curious about everyone’s 61Wh battery wear, so here’s the thread.
Please post relevant working condition, usage style and/or environment that positively or negatively contribute to the battery wear.
Bought the laptop on February 2024(could anyone tell me where to read the batch number), after one year of daily use, my battery has 91% health.

Power supply: The use of low-wattage supply can leads to battery charge-discharge cycle
I used 60W, 65W and 100W power brick most of the time(Good). Used low-wattage ones down to 18W occasionally(less than ten times).
Power management: Affects runtime, might affect wear due to temperature increase
Balance performance on AC and balance power on battery.
Load: higher load increases temperature and high drain(on battery) negatively affects wear
I used this Framework Laptop 13 as my gaming laptop (bad).
Charge limit %: A lower % decreases wear
75% most of the time, charged to 90% less than 10 times, 100% less than 5 times(good). The open-circuit voltage at 75% is about 4.12V
Ambient temperature: Ideal charging temperature is at about 23°C to 25°C, too hot or too cold degrades the battery faster
Temperate environment, from 18°C to 30°C, mostly indoor use (good).
