System Performance

Performance-wise, the inclusion of the new A13 chip should essentially blow the iPhone 8 out of the water given it’s two generations newer than the A11. For more details about the A13, please read our in-depth coverage of the chip in our review of the iPhone 11 series.

Speedometer 2.0 - OS WebView JetStream 2 - OS Webview

In the steady-state Javascript web benchmarks, the iPhone SE unsurprisingly matches the newer iPhone 11. In JetStream, the phone even gets a boost here, which might be due to the newer iOS version. I haven’t had the chance to re-test the older iPhones, but I’m certain the scores will level out across the A13 generation devices.

WebXPRT 3 - OS WebView

On WebXPRT 3, the iPhone SE did score quite a bit worse than the iPhone 11 phones. This test is more interactive in its workloads and more impacted by DVFS responsiveness, rather than just being a continuous stead-state load. It’s very much possible that Apple has tuned down the DVFS of the chip in order to remain at the more power efficient frequency states for more workloads. I haven’t had the time to update Xcode to run our workload ramp test yet – but it’s something that can be easily verified in a follow-up update on the topic.

Update April 29th: 

I was also able to verify the CPU frequencies of the A13 in the iPhone SE, and the phone tracks identical peak frequencies as on the iPhone 11. This means that we're seeing 2.66GHz peak clocks on the Lightning cores when a single core is on, and up to around 2.59GHz when both cores are enabled. The Thunder cores clock in at up to 1.73GHz as well, just as on the iPhone 11’s.

The DVFS of the two phones is also identical – with the same ramp-up times between the SE and the iPhone 11. In general, any performance differences between the new SE and the flagship phones should simply be due to thermal characteristics of the smaller phone, possibly throttling things faster when under more strenuous workloads.

Overall Performance

Whilst I haven’t had too much time on the SE, the first impressions of the device are very much that this is just an as good experience as the iPhone 11 series. Much like on the iPhone 11 series, I actually feel that the raw performance of the hardware is actually hampered by the software, for example animations could be much shorter or even disabled in order to improve the user’s experience of speed and responsiveness. In either case, the iPhone SE’s performance is fantastic, and that’s due to the A13 chipset’s raw power.

    Exactly. And not just those who are not geeks/nerds. I'm tired of being one, tired of fighting Android, tired of inconsistency, tired of having to resort to flashing devices because they're not supported. 5 years on Android, and this SE is now the perfect moment to finally buy a good device that's reasonably priced and that I don't have to mess with for the next 4-5 years. Just for that, take my $399.

    > tired of fighting Android, tired of inconsistency, tired of having to resort to flashing devices because they're not supported

    That was me back when I switched back to the iPhone all the way back when the iPhone 6 Plus was new. Mind you, Android was even worse back then but seeing as how you're saying what you're saying now tells me that Android is still a mess.

    We would never support this kind of bulls**t from Microsoft yet here we are accepting it on phones which usually end up being more expensive than a notebook PC. I see something wrong with this picture.

    You nailed it. It's been 13 years and they still have not figured out how to update us properly. Project treble was supposed to be the great savior that at least would allow OEMs to give us more updates or allow users to install generic Android images on a new phone. The reality is that only a few of the funds released will allow you to do that, and there has been little to no improvement on the amount of updates users get (certainly not the amount of improvement you would expect for a company that has supposedly made OS upgrades such a priority for the past 3 years). I can tell you that my Moto Z2 play had an Android 9 update readied my Motorola and then they proceeded to not seed it to us users for the next 4 months. Fed up, I decided to force the update manually, for which I had to unlock the bootloader (which is allowed by both Google and Motorola) and somehow the OS lost trust on my device when I did that and so I lost the ability to do NFC payments. Are you kidding me? This is a circus. I refuse to be Google's beta tester anymore. I'm done.

    Stop buying crappy 3rd world phone, and get a modern Android device.

    The average person also most likely won't care about software updates, or will actively avoid updates because "why fix something when it isn't broken". Seriously, this 5 year software update thing had to be one of the biggest circlejerks in the tech community. Both mobile OSes are extremely polished and feature rich at this point, and it literally makes no difference whatsoever whether you're using the latest OS or an OS from 1/2 years ago.

    Security updates also makes no difference whatsoever because your average person is never going to have data important enough for people to ever bother attempting these exploits, most of which require physical access to the device.

    Don't get me wrong, I'm not saying that software updates are bad; 5 years support is always better than 2 years. I'm just saying that it does not matter for the average person at all, because they will probably never make use of any of the new features. And this is reflected in the continued success of Android flagships (anywhere that is not the US, at least)

    "Security updates also makes no difference whatsoever because your average person is never going to have data important enough for people to ever bother attempting these exploits, most of which require physical access to the device."

    Not everyone is "the average person".

    We are talking about the average person, are we not? Stop trying to shift the goalposts.
  • Deicidium369 - Sunday, April 26, 2020 - link

    Yeah, the not everyone is "the average person" is kinda implied.....

    I would argue that even the average user nowdays is actively interested in operating system updates and security + got a tech heavy friend who can ask on the topic for more details + media/youtubers are bringing awareness. So you are wrong.

    Also no important data? hahahahah today people keep ALL THEIR LIVES on their phones + on top of that credit cards/payments/bank accounts and whatnot! You have no idea what damage someone can do to you if he got access to those things! No matter if interested person who knowns you or total stranger over the internet with criminal intentions!

    Also you are wrong that the operating systems are not evolving rofl, I can list a lot with both android and ios! And iphones are receiving atleast 6 years of full support, my secondary 6s from 2015 is on ios 14 beta - smooth as silk and fast too + all the features coming with ios 14 are on my phone! Will be supported fully to atleast September 2021 when ios 15 is releasing and that's 6 years! Security updates you say? Apple support with security updates iphones as old as the 4s from 2011!

    Now check the pricing of top android phones and iphones, different picture vs what it was 5 years ago, right?! If they want to copy apple price wise and even surpass them (and that is what happens the last 2 years) - they better also copy what apple does right!

    The amount of people who load aosp on their phones is about as much as the amount of people who rebuild an engine in their garage or build a house from scratch by themselves, meaning basically 0.
    Go tell your parents to install lineageOS on their phone...
