Higher Wattage Chargers

[Colour Sergeant Bourne]

I've always charged my iPhone 11 with an Apple 5 watt charger.

Would using either the Apple 12 watt or 29 watt chargers that came with
my iPads deteriorate the iPhone 11 battery?

Make that a 20 watt charger, not 29.

Very slightly. Faster charging will warm the battery more and heat reduces
a battery's lifespan.

No. I load my iPhone 14 and my wife's SE2020 with a 25W Third-Party
High-Quality-Charger. The charging speed is controlled by the device.
I would be much more careful with wireless chargers. They are so
inefficient that they heat up the battery to extreme levels.

No. I have always used iPad chargers for my iPhones. Since the iPhone 8 Plus.
No problems.

No. It might charge slightly faster, and that might result in a
slightly higher heating of the battery - but likely not enough to matter
in the long term.
