Impressive but with a specialized coprocessor it's not unexpected. It's a bit of a gamble for Apple though, as other ARM SoC's are probably able to bridge the gap in raw single-core and multi-core performance in a year. The whole ML thing is a bit fuzzy for a lot of people even for programmers like me that are still wondering how their regular applications are going to benefit from all this silicon.

Apple doesn't use ARM SoCs. They have their own designs from the PA Semi team and are really just using the ARM instruction set at this point. This is one of the reasons there is such a big performance gap between the top android phones vs the top iPhones.

I don't think that's the reason. That's a similar situation with Kryo / Mongoose / Denver CPUs that are the respective companies' own designs and are really just using the ARM instruction set.

The biggest change was ramping up processor instantly, and then back down to maximize performance. So for launching an app / scrolling, CPU reaches highest state, until that portion is over, and immediately get back to efficiency setting for preserving battery life. Previously CPU time would ramp up slowly.

It's probably paranoia, but I feel like my 5S battery is draining faster since the update. That being said, the performance upgrade is well worth it.

If you're using an 5S still, it's time to update that battery. By now it's what, 5 years old?

It's not, my 6S did the same thing with intensive apps, like Instagram. With IG it's probably ALWAYS ramped up constantly scrolling, playing , downloading. They definitely sacrificed battery life for speed in older phones. My XS lasts like two days though.

What the heck are you doing to get 2 days from your XS? I barely get one!

Don't keep it open all the time?

Why would it be paranoia? Waking up the CPU faster and maximizing its performance will definitely drain the battery faster. I assume the iOS12 update includes a combination of more aggressive waking and maximizing of performance along with a reverting of what they did previously to old phones when they lowered their performance to maintain the battery life of the degraded battery. If you remember there was quite a bi…

>Yes, it's a factor of the new changes, but let's not forget it's primarily a factor of Apple using batteries that lose a significant percentage of their capacity after 2 years in the iPhones, and then hiding much of that by slowing your iPhone down.

Compared to what available and suitable miraculous technology?

I thought so too, but I noticed that the update also increased the display brightness considerably. So maybe that's what's causing the slightly faster battery drain.

My 6S battery was maybe only a few months old(replaced), had same issue with crazy battery drain on IOS12, particularly with Instagram.

It really is the reason. Their CPUs are better than the CPUs that Android phones have access to. You can see this in the benchmarks. Compare Geekbench scores between them:

The fastest iPhone CPU is 44% faster than the fastest Android device CPU.
