> Can you imagine a phone with 3000 mAh removable battery

If you are willing to make it a bit thicker than current phones...about 10% thicker than the original iPhone, you could use 5 NiMH AA batteries [1].

3000 mAh is about what the iPhone XS Max has. If you can get by with around 1900 mAh (about what an iPhone 7 has) you could get that down to 3 AA batteries, or 7 AAAs.

For people who are already using a lot of AA and AAA rechargeable batteries, this gives them a phone that easily fits right in, and as a bonus in an emergency you can use non-rechargeable batteries that you can buy from any convenience store.

[1] 3000 mAh x 3.7 V = 11100 mWh. 11000 mWh / (2000 mAh x 1.1 V / NiMH AA) = 5 NiMH AA.

NiMH can't withstand the power draw (especially the spikes), and can't keep providing the same voltage as it discharges. You'd need extra circuitry to be able to run a smartphone off of them.
