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

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

I would obviously choose battery 2 on a phone with non-replaceable battery, and on powerbanks (edit: with the same principle but scaled to a larger size. Powerbanks are usually much larger.).

With replaceable battery, I wouldn't care that much.

I mean wouldn't you? Think about it long term replacing it is going to be expensive.

I'd still probably choose Battery 2.

For rich people however, the monetary aspect shouldn't matter much.

Also, if I was fed up with replacement at some point (using Battery 1), I would purchase a Battery 2.

If one has money in abundance, one could use Battery 2 most of the times, but have a fresh (non-aged) Battery 1 for occasions such as on trips when one would need that extra capacity and charging speed for photography and 2160p@60fps (or now 3240p and 4320p) filming.

Sure having both would be the best of both worlds. Also would probably be the most resource efficient. However swapping could be a pain perhaps some kind of hybrid device with both could provide a happy medium.
