Will receive my iPhone 8+ in a few days.
How safe is it to use the fast charging function everyday ? Already bought the 29W USB-C Power Adapter and the necessary USB-C cable.
I know it says it charges 50% in 30 minutes. Or up to 50%.
What if I plug it in at 65%? Do I get much benefit from fast charging?

Very safe. Why wouldn't it be safe?

People have weird fear. The other day my girlfriend asked if it’s ok to keep her phone on charge for the whole night.
Theoretically, a battery that charges too quickly or over-charges can overheat and cause a fire (ie. the Galaxy Note 7). Any non-defective device has safeguards to prevent this though. The battery shouldn't take in more current than it can handle, and it should stop drawing a current when it is full.
This may not be what the OP is thinking about, but also theoretically, charging a battery more quickly also puts more stress on it and results in faster wear. I don't know if daily fast charging will have a significant effect on the battery's lifespan though.
Just as an antidotal piece of info, I have been charging my iPhone X for the past 5 months on a 12W iPad charger daily and the battery capacity is still 100%.
From my experience and what I’ve read, the difference between fast charge and the 5W charger for iPhone is like 5x wear.
It's hard to make a full observation unless we know the starting capacity.
In some cases, batteries leave the factory with an actual capacity that is above the design capacity. The Apple Store staff have a tool that can read the real capacity, such as 103%. But iOS won't display anything above 100%.
Correct. The issue was the physical size of the battery was too large, and it had no room to expand.I'm fairly certain fast charging and the Note 7 fires were not connected.
I've only used the 10W iPad charger for years on iPads and iPhones. The charging speed is faster than the 5W iPhone charger. I don't have exact numbers but I feel like it is 25% or more.I just use my iPad charger and that seems plenty fast for me. Not spending more on a damn charger.
