Charging Speed

I believe the iPhone will charge at a faster speed if you use an outlet with a higher current, is that correct? Example, the 12W Apple charger or a 2.4A USB receptacle vs. the small 5W charger.

Is there any way to see what speed it is charging?

I ask because using my 12W iPad charger or 2.4A USB receptacles to charge my iPhone 6S doesn't seem to charge it much faster than the little 5W cube it came with.

Charging any iPhone with any iPad charger will decrease the time needed to charge. However, on the iPhone 8/+/X have fast charge capability. With it, you can charge one of the listed devices from 0 to 50 in about 30 minutes. 6s does not possess that ability.

0-50% seems to not take much more than 30 minutes. It's the end that takes a while.

Is there any way to see the charge speed on the iPhone?

Not quite any, until iPhone 6 the iPhones couldn't be charged at a faster rate than what the included 1 amp adapter provided. As of iPhone 6 that increased to 2.1 amps, and as of iPhone 8 that increased considerably more to support actual "fast charging".

6s can charge 50% in 30mins, I’m using 87W (I can assume 29W will do as well) with USB c to lighting cable.

You can purchase an in line voltage/amperage meter. You can search "usb voltage meter" on Google or Amazon and see some examples.

If I were going to do that I could use one of my Flukes. But I am just wondering if there is a way to tell charging speed from inside the iPhone.
 
I don't think the 12 watt charger rapid charges that iPhone. The most I've gotten out of the 12 watt charger is 1.35 amps that tapers down as the battery charges. The 5 watt cube usually starts about 0.99 amps and tapers down as the battery charges.

actually it does charge the phone twice the amount of the 5W in 30 minutes. there was a good video on 9to5mac
