My UleFone Armor 2 has 4700 mAh, but I would like to limit it to 60% to reduce battery ag**g. The battery in more and more phones is not user-replaceable thanks to Apple's toxic influence on the mobile phone market, 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”.
