Initially, the last iPhone generation could only absorb 5 watts via inductive charging. With iOS 11.2, the power was increased to 7.5 watts.
The future is set to be wireless. The many different headphones have shown this. Charging the battery is also set to be wireless. Many car manufacturers already offer such charging stations in their cars. However, the quick-charge function has not yet been available. To date, an iPhone 8 / 8 Plus & X model requires a cable for this. This is set to change with the new iPhone generation. According to Apple, the iPhone Xs and iPhone Xs Max can charge faster wirelessly. However, no figures have been given for this yet.
Compared to last year, the iGroup has provided more information on this topic. There are no figures on the product page either. The iPhone Xr only has wireless charging - the quick-charge function is not available here.
If previous rumors are to be believed, the power consumption could have increased to at least 10 watts. If this is true, the difference compared to the predecessors would not be great, but would still be noticeable during the charging process.
Doubling of performance – rumor
The China Times originally reported that Apple wants to speed up this type of charging - the new iPhones should be able to absorb up to 15 watts. That would double the power. Apple wants to replace the current charging coil, built on a ferrite polymer basis, with a copper coil. This would be thicker and therefore heavier, but the reduced electrical resistance would heat up the iPhone less and thus enable fast charging.
Apple will most likely provide more precise data on this when the devices are delivered. The 10-watt theory is currently the most likely.
