External battery banks are a far superior solution now that almost everything has standardized on USB and we have power banks supporting high speed charging.

They can be charged with the same power adapter you use to charge your phone, without the need of an extra docking thing.

They can be used to charge any USB-chargeable device.

They are not tied to your specific model, and thus you're not vendor locked with them, making them cheaper and easier to find anywhere in the world.

They come in multiple capacities, allowing you to plan in advance your energy needs and choose the right size bank for your situation.

They are far more sturdier than any modern battery, which makes them more resistant to puncture and bending.

They don't have external contacts that could potentially short in contact with conductive surfaces.

Lots of advantages, but one major downside: you can't pop the empty battery, put a new one and keep working.

There's a reason professional devices (e.g. cameras) still have replaceable batteries.

The people who need this feature should go buy one of the phone models with replaceable batteries.

Reading the comments here, it's obvious that the replaceable battery fans can't even agree on what they want. One commenter wants the back covered in tens of screws for waterproofing. Other commenters want the battery quickly replaceable so they can do hot swaps without missing a beat. Some people are sharing links to phones that have replaceable batteries and getting responses from people saying they'd never buy that phone because it's too big, too ugly, or other reasons.

This is an impossible debate because one side has convinced themselves that it's possible to have their cake and eat it, too: They believe that removable batteries can be implemented without any tradeoffs and the only reason they're not removable is so the phones are forced to become e-waste, which requires you to ignore all of the low cost battery replacement services available.

I use a lot of rechargeable AAA and AA batteries. They have lower voltage than alkaline batteries (by design apparently), which is not normally an issue, but sometimes is a deal breaker. E.g. my thermostat did not like lower voltage AA batteries and shut down prematurely a number of times.

There's challenges adopting standardized rechargeable batteries, e.g. trying to recharge alkaline batteries risks fire/explosion (and you know that will happen far too often given the number of people out there), but if we have had standard battery sizes, voltages, and capacities for rechargeable batteries, things would be so much better.

I have a magnetic wireless power bank that I put on my phone and I can continue using it as normal.

But you can plug in the battery pack and keep working…

Nobody needs to do that with a mobile phone.
