Let's assume two mobile phone batteries that have the same physical size, (edit: same price too), but different properties:
### ***Battery 1***
* 4000 mAh
* 25 Watts maximum charging speed under constant conditions.
* Usable up to 500 charging cycles.
### ***Battery 2***
* 3000 mAh
* 16 Watts maximum charging speed under same conditions.
* Useable up to 50000 charging cycles.
* Weighs 150% as much as *Battery 1*.
Edit: *Useable* means: Before the battery performance starts to plunge and to cause unexpected poweroffs of the device.
## **Which battery would you choose?**
Optionally explain your choice in the comments.

## **Recap:**
| Battery type | 1 | 2 |
|----|----|----|
| Capacity (mAh) | 4000 | 3000 |
| Usual fast charge wattage (normal conditions) | 25 | 16 |
| Useable cycle life (before performance plunge) | 500 | 50000 |
| Relative example weight | 1 | 1.5 |
| Price and size | Same as other | Same as other
