Android 14 introduces battery health monitoring feature.
Originally Published 2 years ago — by Android Authority

Android 14 has added APIs that allow apps to display key battery details such as manufacturing date, date of first use, charging policy, state of health, cycle count, and charging status. An open-source app called Batt can show the number of charging cycles undertaken on the phone, and more details can be accessed by granting the requisite BATTERY_STATS permission through ADB. The feature is not yet ready for public release, but the existence of the APIs indicates that Google is working on it and intends to release it someday.
