SD835 was 72mm^2[1], A10 was 125[2]. A11 and SD845 are actually very similar in die area[3]. However Qualcomm integrates their modem on the SoC and Apple does not, and Apple's CPU cores are still significantly larger as can be seen from die shots. Phone SoC makers don't really publish TDPs and there is a lack of good data about it, but Apple clearly has high peak power draw (and very good idle efficiency). Battery life and thermal throttling observed under a sustained heavy workload is probably the best proxy for measuring SoC power. For example, see GFXBench battery life/throttling results in Anandtech's review[4] of the iPhone 7/plus. Much higher power consumption (and performance, but this is resolution-dependent because it's a graphics benchmark) than the competition.
