iPhone 6 accessories

▼ For a long time, I used my iPhone 5 without a case. But one day, I pulled it out of my pocket by the headphone cable and it dropped on the street. It landed on its corner, which left a little scrape, but otherwise it was fine. But since then I pretty much always used a rubber case when leaving the house. If it had been the iPhone 6, that fall could easily have been much worse with glass curving around the edge. So when I got my iPhone 6, I got one of Apple's cases. I looked at both the silicone and the leather cases, which seemed to be very similar in in feel. In addition to protecting the phones against drops, these cases also add some extra grip so it won't slide out of your hand or pocket as easily. So I saved $10 and got the white silicone case, which nicely wraps around the edges of the phone but leaves the screen and the bottom free.

Apple's silicone case is great for day-to-day use, but it doesn't provide the kind of protection that I need when I go inline skating, where there's always a risk of high speed falls—right on top of my iPhone. So I also got a Trident Kraken AMS case:

Full disclosure: I got the iPhone 5 version for free. That one has three parts: a soft silicone/rubber inner part, and hard plastic front and back parts. It's very thick and heavy, but incredibly sturdy. The iPhone6 version doesn't have a separate silicone/rubber inner part, but rather uses a slightly softer plastic on the inside that sticks out at the corners to absorb impacts. It's much slimmer and only weighs 53 grams. (The iPhone 6 itself weighs 125 grams and Apple's silicone case 17 grams.)

The front part of the Kraken has a plastic screen cover, with a cutout for the fingerprint sensor. The case is supposed to be somewhat splash-resistant; it has covers for most of the openings in the iPhone, but I still wouldn't use it in any kind of serious rain. You also have to be very careful with sand or dust, because this can get in through the hole t the fingerprint sensor and then get wedged between the screen and the plastic cover, possibly leading to scratches. To avoid this, I removed the plastic screen protector. It's glued to the inside of the front part with glue that is easily scraped off. After this, you can still use the case with the screen protector, as it'll stay in place with the phone in the case even without glue. I'm not entirely sure how you're supposed to open the Kraken. The only way that works for me is with the tip of a knife, and even then it's not easy.

On the back of the Kraken you can attach accessories such as a suction cup for sticking the phone to a car dashboard or windshield, a tripod attachment or a bicycle steer attachment. I got the latter:

This allows me to use my iPhone to help me navigate when cycling, which I'll talk about in a later post.

The last accessory I want to talk about is one that's not really compatible with the iPhone 6: the iPhone 5S dock. I really liked putting my iPhone 5 in the dock on the nightstand to charge overnight and play some music through the AUX in on my radio alarm clock. Also, my third-party lightning cable works well when I connect it to the dock (with the iPhone 5), but it's never worked when I connect it directly to the iPhone 6. So I took my Swiss army knife and cut away the sides to allow the iPhone 6 to fit in the dock:

It's not going to win me any design prizes, but it works:

The iPhone 6 still complains about the non-authentic cable, but it charges just fine off of it, and the audio out through the dock's 3.5 mm port also works.

My podcast listening workflow: iTunes/Podcasts, Pocket Casts and (not) Overcast

▼ In 2013, I wrote a pretty long story with advice to podcast app developers. Today, someone on Twitter asked me if I ever found a good solution to the "catching up" use case. I guess the short answer would be "no", but did settle on a podcast listening workflow that works fairly well. So let me explain how I listen to podcasts these days.

After switching from an iPod to the iPhone, I continued to use Apple's built-in podcast functionality for many years. Of course Apple couldn't resist messing with a good thing, so they released the Podcasts app. For a while, you could still use the Music app to listen to podcasts, but that hasn't been possible for a few years now. A few years earlier, Apple had rejected the first third party podcast podcast app, and later changed their minds about that. A few years later, there was a healthy niche of podcasting apps in the store. And then last year Marco Arment released Overcast.

After I reviewed a bunch of podcast apps for Ars Technica three years ago, I settled on Pocket Casts as my main podcast player. However, I never abandoned Apple's Podcasts app, for two reasons.

First, sometimes I can't use my iPhone, and then it's nice to be able to listen to podcasts using my iPod. So for that reason alone I keep a few podcasts around in iTunes on my computer and sync those to my old iPod as well as my iPhone. Second, going through feeds and selecting which episodes to download and which to skip is easier on a computer with a big screen and a keyboard. Also, long lists of back episodes that I accumulate for a rainy day don't get in the way on iTunes and the Podcasts app. However, iTunes keeps getting harder to use, and Podcasts is far from perfect, especially now that it keeps around old episodes for 24 hours. And not being able to use the headphone clicker to skip ahead can be very frustrating.

When Overcast came out, I obviously wanted to try it out. I found the $5 price for the full version a bit steep, and I don't like the whole in-app purchase thing. The Overcast unlock is my one and only in-app purchase. But I decided that I'd be writing about Overcast here on my blog so the $5 would be worth it. And then I didn't write about Overcast and stopped using it, so it wasn't...

The first week, my main problem with Overcast was that many functions were extremely non-obvious to me. I've forgotten which functions were so problematic, but there was definitely a learning curve involved. However, eventually I figured things out and the app became much more usable. I like the smart speed, which speeds up playback by removing pauses. In theory, I also like the idea of normalizing the volume, but in practice I didn't use it. Another thing that's great in theory but doesn't really do it for me in practice is the smart playlist ordering. Yes, there are some podcasts where I immediately want to cue up a new episode, and others where I'm not in a hurry to listen. But in practice I keep changing the order so often that the feature doesn't really help much. Manually adding/removing episodes from a playlist is way too hard.

However, the one thing that made me stop using Overcast is that it always insists on continuing to play—even after you reach the end of your playlist. I find that insanely annoying. Yes, you can make Overcast stop playing at the end of the current episode, but there is no workable way to play a bunch of episodes and then stop.

So I went back to Pocket Casts. I like the look of Pocket Casts better, and in the current version "up next" works very well: when you add episodes, they're put at the end of the "up next" list. You can easily do this with a long press on an episode and then one additional tap. Unfortunately, removing episodes from the up next list is much harder. You'd think that a swipe to the left would do it, but that marks the episode as played, which is pretty much never what I want in the up next list.

To finally answer the question on Twitter: Pocket Cast doesn't handle catching up exactly the way I'd like, but it works. When you subscribe to a podcast, the latest episode shows as new and all older ones as played. When I decide I want to catch up and listen to all old episodes or some old episodes, I just scroll to the bottom of the episode list, tapping "show older episodes" as needed. I then download a few, and listen to those. I have to take care that I go back and download more before I listen to all the ones I downloaded, because having at least one downloaded but unplayed episode allows me to keep track of how far in the feed I got.

Yes, it would be nice if more episodes would be downloaded automatically as I listened to older episodes, but downloading them manually is no big deal. The only annoying part is that the downloaded episodes move to the "new" section at the top of the episode list, so it's not obvious where in the "played" section the oldest unlistened episode resides. A solution would be to mark the whole feed as new, but then all the unlistened episodes would clutter up my "all" list, which also isn't great.

Update: it turns out that the swipe-to-the-left gesture that normally marks podcasts as "old" also marks old ones as new.

Comparing depth of field: iPhone 6 vs camera

▼ In my post about the iPhone 6 as a camera, I talked about how phone cameras have extensive depth of field (objects near and far are both in focus) compared to regular cameras because their sensors are so small. This is even more pronounced in the iPhone 6 because it has a wide angle lens.

So I thought I'd do some comparisons. This is a photo taken with the iPhone 6. The camera is focussed at a distance of maybe 30 centimeters, so the parliament buildings in the distance are out of focus.

This is the same image taken with a Canon SX280 compact camera with a 20x zoom lens. At this wide angle, the minimum aperture of the zoom lens is f/3.5, which lets in only half of the light that the iPhone's f/2.2 lens lets in. The focal length of the lens is just under 6 mm, while that of the iPhone is just over 4 mm. So the sensor of the Canon camera is 1.4 times larger than that of the iPhone. The depth of field looks a bit larger than that of the iPhone.

Last but not least, the same image taken with a Nikon D7100 with an 18-55 mm lens at 18 mm, resulting in an image that's a bit wider than that of the iPhone and the SX280. The aperture is also f/3.5. The sensor of the Nikon is about 4.5 times larger than that of the iPhone, so even though the lens is a bit wider and the aperture a stop smaller, the depth of field is a lot smaller.

Here's two 100% zooms of the middle of the image. Click on the links to load the specified version of the image: iPhone 6, Canon SX280 or Nikon D7100. The ones with the ∞ symbol are focussed at infinity and should provide a sharp image, the others are focussed at 30 cm and should be more or less blurry. I've also included Nikon versions at f/8 and f/22, so you can see the effect of a smaller aperture on depth of field. Select two images of your choice to compare them.

If you compare the f/22 ∞ version to the f/3.5 ∞ or f/8 ∞ version, you'll see that the sharpness actually goes down at very small aperture sizes. Also, the f/8 ∞ is somewhat sharper than the f/3.5 ∞ version—f/8 is usually the sharpest aperture for most DSLR lenses. However, the SX280 already starts to suffer from the diffraction effect at f/8, so the f/8 ∞ version isn't quite as sharp as the f/3.5 ∞ version, and f/8 is the smallest aperture.

Should Swiss watch makers attempt a smartwatch?

▼ Matt Richman thinks that TAG Heuer, maker of Swiss luxury watches, shouldn't waste time making a smartwatch:

TAG Heuer’s smartwatch won’t sell. There’s no market for it.

In order to have even a chance of being as feature-rich as Apple Watch, then, TAG’s smartwatch will have to pair with an Android phone. However, TAG wearers aren’t Android users. Rich people buy TAG watches, but rich people don’t buy Android phones.

I couldn't disagree more.

At this point, the Apple Watch is barely more than vaporware. The ascend of the smartwatch is in the very early stages. All kinds of things can happen.

Yes, Apple has three advantages: the most desirable potential smartwatch wearers tend to be iPhone users, and Apple can integrate the Apple Watch and the iPhone any way they see fit. They're also in the position to build custom chips.

So yes, Apple is going to be in the best position to do what Apple is doing: building a smartwatch that's barely more than a dumb terminal that uses the iPhone's computing power. However, that's more a limitation than a feature. Wouldn't a smartwatch with its own cellular connectivity be much better? It's probably too early for that right now, but that could change a few years down the road.

Also, how necessary is the deep integration between the phone and the watch? Most watch functions that need an assist from the phone could work just fine using a third-party app that runs in the background on the iPhone. The main issue would be the phone-related features, but apparently the Pebble can hook into those to a reasonable extent today.

Last but not least, Apple needs to sell tens of millions of watches to make for a viable new product category. This means the average price will have to be much lower than the price of a Swiss luxury watch. So Apple needs to depend on scale to provide value, while a company like TAG Hueur can use much more expensive materials and processes and still have good margins, although they'd have to depend more on off-the-shelf electronics.

Sure, it's entirely possible that the Swiss luxury watch makers are in trouble. But it's still way too early to write them off.

iPhone 6 network speed

▼ It was only a few months ago that I first got 4G/LTE working on my iPhone 5 using a Vodafone NL prepaid SIM, and the results weren't very spectacular: at home, I got 12 Mbps down, which is actually slightly slower than the 3G I get from KPN. Up speed was respectable at 5 or 6 Mbps. In the city center I got slightly better speeds at 20/20 Mbps.

So I was very curious what the iPhone 6, which supports many more LTE frequency bands, would do on the Vodafone LTE network. So I popped in the SIM... and nothing happened. Despite my best efforts and many reboots, I was stuck on 3G for almost a day. Or even GPRS on the 2G network:

Not sure if that did the trick, but I finally got 4G after resetting my network settings. When I first popped in the SIM, I got a text message with a link to a provisioning profile, but that seems to give me the same settings that also appear automatically. However, when I later put my KPN SIM back in the phone, I couldn't get any data service until I removed the Vodafone provisioning profile.

I did some testing as I was traveling home by train, and I got various speeds, starting at about 20/20 Mbps down and up and going as high as 68/36 Mbps:

It's too bad that data plans are so limited and/or expensive, as you can burn though a gigabyte of data in two minutes at these speeds. Vodafone NL apparently doesn't support Voice over LTE yet, as I dropped down to 3G as soon as I made a voice call.

Wi-Fi has also been improved—but only on the 5 GHz band. On the 2.4 GHz band, you still get a maximum of 72 Mbps 802.11n:

The iPhone 5 and 5S did 150 Mbps 802.11n on the 5 GHz band; the iPhone 6 adds 433 Mbps 802.11ac:

These speeds are a good deal lower than what you get on a computer because computers usually have three antennas, which means they can be three times as fast if three data streams can reach the antennas independently. With only one Wi-Fi antenna, the iPhone is limited to 433 Mbps, but it'll reach that maximum more often.

Transferring files between my computer and the iPhone using iTunes, I got about 7 megabytes per second on the 2.4 GHz band, which completely saturates the channel. I got 15 to 22 Mbps on 5 GHz, which doesn't come close to saturating the channel. So if you're still using a 2.4 GHz only Wi-Fi base station or home router, you may want to consider upgrading it to something that supports at least 802.11n—preferably 802.11ac—on the 5 GHz band and you'll get better speed more consistently.

I would have loved to test Bluetooth 4.0 performance, but the iPhone doesn't support file transfers over Bluetooth. Annoying. Nokia could do this more than ten years ago. Apparently they want us to use their proprietary AirDrop system instead. I've seen this work very quickly between two Macs recently, but between my Mac and my iPhone, it takes forever for the two to "see" each other and the transfers then happen at about 5 megabytes per second.

Bottom line: the iPhone 6's networking can be very fast, but it all depends on the SIMs, Wi-Fi base stations, frequency bands and transfer protocols. So I'm glad it still comes with a USB cable, even if it's only USB 2.
