📊 Battery Health vs Battery Capacity: What’s the Difference?
Milliampere-hours (mAh) vs degradation percentage. How battery fuel gauge ICs calculate state of health (SOH) and peak performance capability.
📊 Decoding Battery Health vs Battery Capacity
Many users confuse a battery's original Design Capacity (mAh) with its current State of Health (SOH %).
🔍 Key Distinctions
-
Battery Capacity (mAh): The total volume of electrical energy the battery can store when 100% charged (e.g. 4,500 mAh on a Galaxy S24).
-
Battery Health (%): The ratio of current maximum storage compared to when the battery was brand new from the factory. When health drops below 80%, voltage sags trigger sudden shutdowns under processor spikes.
