I just bought a Samsung 25W wall charger, it was half price. My phone supports 18W fast charging but it only came with a 10W charger. Also got a 1m type C 100W usb cable from aliexpress for 4$CA, it has LEDs that tell you how much of the battery is charged.
New phones don’t even come with chargers anymore, ridiculous, thanks to Apple. First they removed the earphones, then AUX plug and now the chargers. Apple started these changes and others did the same. I still use the AKG earphones that came with my Samsung S9
Is it true that fast charging shortens battery life?
Yes, it does tend to degrade batteries faster. That’s why some phones come in built with charging management options. You can choose if you want to charge quickly within an hour or two. Or overnight.
Makes me wonder how much of it will be noticeable to user? Some people change their phones within a year or two. Others maybe 5-6 years.
