Both heat and high state of charge wear the battery faster, but the combination of both is far more destructive than either alone. Keeping the battery at 40% charge will greatly increase its lifespan. A typical Li-ion cell stored at 60C and 40% charge for one year will still have 75% of its capacity, while storage at 60C and 100% charge will have it down to 60% capacity in three months. https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries https://batteryuniversity.com/article/bu-808-how-to-prolong-...
