What is the iphone tri-axial accelerometer precision and range?

I want to know what the precision and range of the accelerometers in the iphone is, and if it is different across different models. I understand from here https://www.macrumors.com/2014/09/26/iphone-6-6-plus-two-accelerometers/ that the iphone 6 had two tri-axial accelerometer chips, both with a range that could be set to ±2g, ±4g, ±8g, or ±16g, but they differed in precision (the lower power chip having less precision).

I also believe that the default range on the iphone is set to ±2g.

So I want to know what the precision and range of acceleration is in iphones more recent than the 6, and if they still have a chip (or chips) that are set to ±2g by default, but can be used at higher accelerations of ±4g, ±8g, or ±16g. Ideally this would include information upto and including the iphone 12 mini.

Finally, if it is possible to use them to measure accelerations higher than the default ±2g, how is the required range set in an app?
