Now, batteries degrade faster if they are exposed to high temperatures. They degrade insanely fast if they are also above 80% whilst being at high temps.
Every other laptop manufacturer out there offers a way to limit the full battery charge. Asus, HP, Lenovo, Acer, XMG - you name it. You just set the max battery charge in % (usually it's 60/80/100%) in BIOS and/or software - and there you go, Windows instantly stops charging the battery once it reaches 60%.
This could and WILL save batteries in the future. Please ADD BATTERY MANAGEMENT TO SYNAPSE
