My UleFone Armor 2 has a 4700mAh battery and I would like to limit the charging to 60% to reduce battery aging. The batteries in most of the phones are not user-replaceable and I am worried that a factory/service battery replacement might affect water resistance negatively.
How can I limit the charging to 60%? (But not limiting charging speed. I love fast charging.)
Lenovo ThinkPads have a built-in feature that does this, called “battery preservation mode”.
