The feature does this by monitoring your battery&amp;#x27;s temperature history and its charging patterns.&lt;p&gt;&amp;gt; Based on the measurements that it collects, battery health management may reduce your battery&amp;#x27;s maximum charge when in this mode. This happens as needed to ensure that your battery charges to a level that&amp;#x27;s optimized for your usage—reducing wear on the battery, and slowing its chemical aging.&lt;p&gt;Sound great. I hope this means no more swollen batteries.
