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'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.

Also, Battery 2 should still be good enough in most everyday use cases.

In 2014, 15 watts (Galaxy Note 4) was considered outstanding.

15W in 2020 isn't any less than 15W in 2014.

I was more thinking like a house battery type scenario where you had the super charge cycle battery for short outages and the higher capacity one for longer outages.
