In my rooted Android devices I have faithfully adhered to limiting charge between 30-80%. Probably that's why even after 4+ years in 2 of my oldest devices (2 & 3 years of intensive usage) battery health is still in the 85-90% range and they still deliver 8-10 hour SoT. Considering the difficulty in obtaining a replacement battery for Kindles in my country I would like to prolong the battery life as far as possible. After jailbreak I have no desire to get an Android based one.
Is this possible? Thanks.
