Some of us prefer ‘slow charging’ (overnight) to maximize battery longevity by using Apple’s 5W charger:
Apple's slowest iPhone charger with an outdated 5W USB port is no longer available to purchase in some countries around the world. As noted by...

I keep my iPhones forever and I don’t upgrade frequently.
I charge with a 5w Power Adapter. I’m now using an iPhone 16 Plus. Is it slow? Yes! But I don’t really care. I have my iPad’s 20w Power Adapter if I ever need faster charging… and that’s as fast as I need.
50% in 20 minutes is cool but just as theoretical as the 50% in 30 minutes of my 16 Plus. Apple can do 50% in 3 minutes and I still wouldn’t care.
I’m a light user in terms of apps used and as a result I typically finish the day with 70-80% after about 6-8 hours of SOT. Even heavy camera days mean that I finish the day with 60-70% after 5-6 hours of SOT.
In fact, I’d sometimes like my 5w charger to be slower! (Or for Optimised Battery Charging to be better, actually). It consistently finishes charging by 03:30. (With optimised, if I were to let it charge freely to 100% it would finish far earlier). I’ve never unplugged my iPhone before 05:00. It should finish at 05:00 but it never changes.
So, if I start the day with 100% there’s practically zero chance of me running out of battery on my 16 Plus. Not only that, there’s a very slim chance of me ending the day with less than 50%.
I doubt I’ll ever go faster than 5w. Luckily I got a Belkin USB-C to USB-A cable, as Apple does not sell one.
