> a battery that I don’t need to replace for 3-4 years anyway.
This is not just about battery replacement. I used to keep several fully charged batteries stocked in my rucksack whenever I went hiking or anywhere else that was remote. After a day of taking photos in the wild its nice to be able to just chuck in a fresh batttery and off you go.
I feel like this feature of phones was not only lost, but pretty much forgotten about after smartphones stopped including user replaceable batteries.
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.
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.
Probably not by design. Battery peak storage levels are set by chemistry, and not really subject to tweaking - which is why there are tons of 1.5 V battery types, but not a single 2.0 V battery out there.
There are a few flashlights that have USB PD power bank functionality and also run on 18650 or 21700 rechargeable, replaceable Li-ion cells. I bought a Loop Gear SK05 Pro to replace Anker power banks for this use case.

There are several high end phones with removable batteries. You should buy one of them if this feature is important to you.
This movement to force everyone's phones to pay the costs of removable batteries to address these really niche use cases is not great.
> he costs of removable batteries to address these really niche use cases
You seem to have completely missed the primary point of all this, which is to reducew ewaste. That fact that it also satisfies some niche uses cases is a great bonus!

Everyone acting like iPhones and mainstream Android phones become e-waste after 3 years is just making specious arguments.
Why does the average phone user know more about phone batteries and replacing them than all of these commenters acting like iPhones are becoming e-waste after a couple years?
I think I know more people with 4-6 year old iPhones than with an iPhone 17.
Apple stores will replace the battery for you for a very reasonable fee and the phone will carry on for many years more. This is a common thing to do and you can find battery replacement services for popular Android phones too.
Replaceable batteries are one thing, but truly hot swappable batteries like you're asking for will absolutely effect the waterproofing and add a lot of weight/size. Is there a reason you can't just bring a battery pack in your rucksack? They make magnetic ones you can slap on the back and be on your way.
Continuing to take photos with a battery pack hanging off a device is no where near as simple as popping in a fresh 100% battery and coninuing as normal.
just to note, wireless charging is very inefficient. From the page you linked:
"Due to a 30% to 45% energy loss in battery cells and conversion circuitry, a fully charged 5,000 mAh power bank typically offers an estimated 2,750 to 3,500mAh to power devices"
yes exactly my point, I dont want to wait to charge up my device with another device. I just want to pop in a fresh 100% battery. It used to be so simple.
There's tons of MagSafe battery packs for iPhones. They charge the phone continuously. There's no need to let the phone drop to zero before attaching the battery pack. There's also cases with integral batteries. I assume there's Android equivalents for various phones.
I'd say these are more convenient than extra swappable batteries. They have integral charge controllers and charge via USB. There's no need to charge them in the phone or have to buy some extra external battery charger.
They’re incredibly wasteful due to inefficient power transfer which is a huge issue with wireless charging.
And it’s not just wireless that’s inefficient; with a usb connection you’ll typically lose at least 15% in a good buck/boost stage and there’s 2 involved in a usb battery pack: one in the battery pack itself to step up/down from pack voltage to the negotiated PD voltage, and then another lossy stage in the phone stepping down to 3.7v.
My powerbrick connects to the back of my phone. Form factor wise it's pretty close to my extra large StarTac removable battery that I would carry around.
Apologies, my coment came off a bit unecessarily aggressive.
It is my preference to have user replaceable batteries, and my belief is that they were only removed to make phones become obselete quicker and cause higher turnover of purchased phones.

My iPhone 12 is six years old. I replaced the battery last year. While it probably won't be workable on cellular networks in six years, outside of physical damage there's little reason it'll stop working. My original iPhone from 2007 still boots up and runs. There's no GSM service for it to talk to but it runs as a WiFi only iPod just fine if I really wanted.
The idea that non-replaceable batteries is a conspiracy to lower the lifetime of devices is sort of silly. Flagship phones are made of incredibly sturdy materials. If they were designed to be disposable they'd have a bunch of sacrificial structural elements to limit their lifetime. Instead they're built as well as they can possibly be built.
A flagship phone will be left behind in CPU power running bloated JavaScript blogs or cellular service long before any internal component fails. Non-replaceable batteries are about hitting a capacity/size target more than anything else. Replaceable batteries enforce constraints on a phone's design that non-replaceable ones do not have.
