Woah that's cool stuff. I have an app on my phone that tells my current charging stats so I'll let my phone drop down to 5% or so today and see how many watts it's pulling.

At lower battery it really is fast I can leave it on for 5-10 minutes and be back upto 50% after that it starts to charge a bit slower.

BTW I've never owned an iPhone but I like to stay educated... How long do the latest iPhones take to charge? 10W sounds like nothing but I also believe iPhones have significantly smaller batteries/better optimization than Androids.

my OnePlus 8t charges at 65W meaning 0-100 in about 35 minutes. It's freaking amazing and I'm sad I won't be buying OnePlus again since the fast charging has spoiled me.

As for battery run time etc... 2 years of fast charging to 100% almost every day later and I am at approximately 85% battery health and still getting 4-5 hours of screen on time with heavy usage. It's a 4500mah battery
