After some research, I learned that charging a lithium cell to 85% will extend it's lifespan by 210%. The small decrease in capacity is little concern to me. I have 2 Samsung tablets with the same operating system as the phone, and one of the options is to charge the battery to only 85% to extend battery longevity.
