I'd like to see an option to limit fast charging as it does lead to increased wear and decreased battery life span. 99% of the time 5W charging is plenty for my needs. Maybe there could be a 'slow charge at night' option. Whilst during the day if I'm charging I likely do want it to charge as fast as possible.
Got a tip for us?

iPhone 13 May Support 25W Fast Charge Power Adapter

This really isn’t that big a deal as the iPhone 12 Pro Max can already charge at a peak of 24 watts, according to my venerable usb-c tester.
Apple’s 30W usb-c charger and the 12 pro max negotiate 14.9 volts and 1.6 amps max, while other usb-c chargers negotiate 9 volts and approx 2.7 amps max, with a steady decline in amperage as the battery fills up. The tech is already in place.

Whoa... A shameless money grab! Shiver me timbers!
Some people will like having faster charging and will buy the more powerful charger. Some people won't care and pass on upgrading their charger, and use the one they already own. It's nice having that option.
Are you suggesting that's the only difference between the 12 and 13, and thus the only reason to upgrade?
This change is no different than the incremental improvements we see with WiFi speeds, or any of the other things that get upgraded as technology changes. For years, I’ve been using and upgrading my charging blocks, since I got the first 12w charger with my then iPad, given it shortened charging time with my iPhone. And with the now great quality inexpensive 20w and higher third party charging bricks, there really isn’t a reason to buy Apple branded bricks.
I also use one of my 5W charging bricks. Optimize charging works for me every night and I carry a Anker charger box for work, since my truck’s car charger port isn’t working. I rarely have to use the charger box.
In the future it only gets worse!

If it isn't USB-C who give a crap. Staying with Lightening at this point is just pure stubbornness. Apple should switch to USB-C to make connecting to their own computers easier, unified cables, car connections, charges and headphones. The only reason not to is because they get paid for lightening patents.
We’ve had these in the USB (A/C) line up so far.
5,10,12,18,20,(25),29,30,61,87,96
But why the oddball 25 W limit on USB C to Lightning charging? Why don't they just raise it to 27 W, a wattage commonly used by many USB C chargers?
Speaking for myself only - with overnight charging while I'm sleeping, I don't really care if it takes seven hours or one hour... probably rather the slower charging for battery longevity.
I have higher wattage USBC multi-port chargers at a couple other locations in the house (kitchen, office), so faster charging capability could be handy. But again I already have these and thus don't need yet another single-port brick in the box.
We’ll end up with as many chargers as iPads have screen sizes.
When they stop making billions off power adapters. Their relentless greed isn't their fault. It's ours.
What they could do is allow 25w charging with the iPhone 12, or simply sell a 25w charger (since release) instead of a 20w one.
Where did I say I have to buy it? However, if you want the fastest charging, you’ll need to buy it.
I expect for every battery capacity increase a new adaptor will be released. Why didn’t Apple do this in the past when they included the adapter. Reason is simple, price.
what happened to the statement they made about environmental reasons. they should give a 40W power adaptor for free for all and then talk all they want and change for the next 4 years 
I hear ya. Thanks!
It's funny that there are some Android phones (OnePlus?) that brag about their 80W charging or whatever...
"Full Charge in 15 Minutes!!!"
Craziness!
It's a naturally evolving system. No need to upgrade until you buy another power adapter.
I'm sure 5w will still work...and if you have an ipad prod it comes with a beefy chargers...although you will be on the hood for a type c to lightning cable.
