What is mAh?
Milliampere-hour - a unit measuring battery capacity in smartphones.
mAh (milliampere-hour) is a unit of electrical charge commonly used to measure the capacity of batteries in smartphones and other portable devices.
What mAh Means
A battery rated at 5000mAh can theoretically supply 5000 milliamperes for one hour, or 500 milliamperes for 10 hours. Higher mAh generally means longer battery life.
| Typical Smartphone Batteries: | |
|---|---|
| ---------- | ------------------- |
| Compact phones | 3000-4000 mAh |
| Standard phones | 4000-5000 mAh |
| Large phones | 5000-6000 mAh |
| Gaming/rugged | 6000+ mAh |
Why mAh Isn't Everything
- Processor Efficiency: Newer chips use less power
- Display Technology: LTPO AMOLED saves power
- Software Optimization: Efficient apps matter
- Screen Size: Larger screens use more power
- Network Usage: 5G uses more power than 4G
Battery life depends on more than capacity:
Battery Health
Over time, batteries lose capacity. A 5000mAh battery might only hold 4500mAh after 2 years of use.
