iPhone 15 Pro iPhone 15 Pro Charge Speed

[RDowson]

I keep seeing reviews showing the iPhone 15 (and Pro model) charging at around 25-27W.
I’ve tested on two devices now (15 and 15 Pro) and I’m struggling to see much more than 20W.
I’ve used various Apple chargers ranging from 29W to 96W.
Readings were taken at various states of charge, ranging from 1%.
Does anyone else see this? Is my meter unreliable?

At below 50% charge you should get closer to 27 watts.

At below 50% charge you should get closer to 27 watts.

Definitely not seeing that.
Wonder if it’s the meter that’s the issue.

On my 15PM I also get 27W at below 50%. I tested with my Apple Macbook USB-C 96W charger.

I think the higher input wattage applies to the Plus and Pro Max models because of the larger battery.

I'd only 20W USB-C fast charge in a car to get 0-50% battery within 30 mins.

Slow charge overnight using a 5-12W USB-A charger

On my 15PM I also get 27W at below 50%. I tested with my Apple Macbook USB-C 96W charger.

It would be interesting to see if the faster speeds are limited to the larger batteries in the Plus and Max models then.
I’ve got another USB C tester coming today so that will allow me to confirm if my existing tester is reading accurately or not.

UPDATE: I found a video on the 15 Pro 6.1" charging and when it is very low for this person it seems to start at 25W then somewhere around the 10-15% mark it changes to 20W but you did say you tested it at 1% so not sure.

Just tested with a second USB tester and I’m getting the same readings.
It will occasionally spike at 24/25W but for less than a second before going back to around the 20/21W mark.

I believe temperature plays a roll, so repeated charging tests and other device activity could potentially slow down charging speeds.

Think we’ve found the reason. Seems the non plus and max models are limited to around 20W.
