I’m under the impression (probably created by Apple) that anything not tailor made by them is worse. I can charge my phone with any 5V source and the right connector but it’s always slower than an Apple charger. Why, I don’t know. Could be that the phone just recognizes the Apple charger and refuses to charge full speed otherwise. But is there anything that could be done about that? It’s malicious compliance at worst or just a lowest common denominator standard at best. I use third party batteries and the phone refuses to reliably gauge their health (understandable) which makes them objectively worse. The list goes on. It’s bad for the wallet and the environment but people still want to pay for complete tailor made ecosystems and I’m not optimistic that it can change completely via regulation. USB-C standardization lets me charge with a third party charger in a pinch but it still doesn’t rid me of Apple’s monopoly on good iPhone chargers!
