Do you mean milliwatts (or watts)? Cuz milliamps alone wouldn't really be helpful.
Got a tip for us?

iOS 18's Battery Section Tells You If You Used a Slow Charger

I don't get why they can't just tell you WHEN YOU PLUG IN THE CHARGER. A lot of Android phones will say "Charging rapidly" when you connect a good charger so you know you're all set, or they'll say "Charging slowly" when it's a crap charger.
I've always found it weird how Apple likes to withhold useful information. They've gotten a little better about it in the past few years but there's still much to do.

The irony is most people would just keep using the chargers they had around the house after upgrading their phones. When Apple started including the 18W charger with the 11 series, a lot of those stayed in the boxes and people... KEPT using the old 5W chargers they had laying around the house. This was one of the reason they stopped including chargers!
Most people don't really follow tech; they don't know their older chargers were slow. A message telling them that would be useful to get folks to realize they should upgrade. The change to USB-C is going to force a lot of people using older chargers to upgrade, so it's less pressing than it was, but it's still a good idea.
(and you know at least some people will just buy a USB-A to C cable and KEEP using those old chargers around the house. Sigh.)
It is a bad thing... for Apple.
Fast charging degrades the battery faster, as does wireless charging, which means people need to either pay for a battery replacement, or get a new phone.
I've previously had the Apple store staff book me an appointment for an A$80 battery change on an iPhone 8, only to tell me when I arrived that they couldn't do it that day and that my 'best option' was to upgrade to an iPhone 13 for A$1500. I insisted on the battery swap and suddenly they could do it.
Battery life is a major reason people upgrade their device. With a simple battery swap, the overwhelming majority of people should be able to keep their phones for 5-6 years before upgrading - some even longer.
Agreed about the longevity. My plan for my 15PM. minimum 3 years, ideally 4 years, even better 5 years.
I just use the old 5W USB-A charger to charge my iPhone 15 Pro.
Because of the large battery, I only need to charge it overnight anyway.
The 5W is also good for the battery.
I don't understand all the hype around super mega fast charging that makes the phone really hot.

Mother earth is busy in filming another mocumentary.
Everyone ideally should be upgrading to GaN chargers, they are better than older silicon chargers in every way by providing the cleanest possible charge with minimal heat, especially with multiple devices via usb c to usb c.

I always charge my devices slowly, is better for the battery in the end.
While it is still true that fast charging is not good for your battery, there have been many efforts to lower that effect. For example a battery is divided into four smaller batteries. That takes up slightly more space, but now 60 Watt charging means that each individual battery is charged with 15 Watts.
The main reason why fast charging hurts the battery is the heat. So if there are sensor in the phone that slow down charging at a certain heat level, the effect can be reduced. Some modern smartphones even having cooling pipes to coll the battery. Also keep in mind that having your phone in a hot environment does the same. It makes no difference if the heat comes from the charging or from the sun.

Slower you charge = better for the battery. Less heat is generated and lifespan is better.
Slow charging notice and no switch to charge slow? Typical Apple style.
This label looks as if charging with 5W is bad lol. Idk about others, but for myself I have many proofs that slow charging improves battery life in long term – less heat when charging, less strain on cells, less chance battery will degrade fast.
Example: I never charge my SE with 15w charger (which it supports). While phone charges almost instantly it overheats much to the degree it becomes hot to hold in hands. With my old and trusty iPhone 5 era charger the phone just gradually charges and even seems to hold battery longer (idk why tho)

Considering my iPhone 14 Pro (bought at launch) battery is currently at 85% capacity since launch and I’ve used a fast charger, but my wife’s 13 Pro (bought at launch) battery is a good 5% on top of that and she’s used a slow charger I know what I’ll be using going forward when I get a new handset.
No. On USB-A without Power Delivery it’s >10 Watts.
For USB-C without Power Delivery, I have confirmed >14 W real world here:
Charging MacBooks - PD vs non-PD chargers. Eaton says M2 MBAs are not compatible with 15 W non-PD chargers. Some tests inside (but not with MBA).
That 15 W (5 V x 3 A) Eaton USB-C outlet can maintain the charge on my 12" MacBook for the most part, but during usage it won't increase charge. A 30 Watt Leviton USB-C outlet with Power Delivery works much, much better. I've tested a bunch of different products now, with different chargers...

Apple silicon has reached the point where the equation P = V x I can be computed in real time.
With the power of Apple silicon you can now know if your charger is slow.
We are so excited to see what you do with your older slow chargers. 😆😜

That's what I thought! Slow charging is the best way to protect our batteries from depreciation.
The official USB type A/B plug specification was limited to 2.5Watts for the first generation but was later extended to 7.5Watts (1.5A @ 5 Volt). With USB2 and USB3 standards several brands, including Apple, have developed their own specifications/protocols to enable higher power over regular USB type A cables. It is possible to charge up to 36Watts over an type A USB cable with Qualcomm's QC3.0
Unfortunately adapters from various brands do not always support all charging specifications/protocols out there. It is not unusual that an adapter from brand X won't fast charge a device from brand Y. Especially those that were included with the phone/tablet/computer.
To make things even more annoying, the majority of high power adapters that do support multiple (super) fast charge protocols, only one of those can be active on its ports at the same time. While there are exceptions, usually there's no mix & match. For example, I have this power brick that supports almost all charging specifications available. It can perfectly Fast Charge a Samsung, but as soon as someone connects their wireless headphone for charging on that same brick, the Samsung is forced back to the slower USB2.0 charging standard. It will only keep on using Samsung Fast Charge if there's another Samsung phone connected. Same for QualComm's fast charging method, it can't be mixed. And it doesn't matter if its USB-A or C-type. One 60Watt charging brick I got only delivers that power to something like a Macbook when only this device is connected. As soon as an unsignificant 5Watt device is connected on one of the USB-A ports, the charging power on the USB-C port is reduced to 45Watts or less.
I'm still looking for a decent large charging brick that has fully independent USB charging ports and doesn't heat up as many do. But for the nightstand I use small, high efficient power adapter for a wireless slow charging pad that doesn't heat up the phone. iOS seems to adapt the charging speed nicely according to my working schedule.
Some may like to look here for intensive tests

Older versions of iOS around the the of the x actually made the device double vibrate if plugged into a fast charger. They removed it later but that was always super helpful.
