On watchOS 2 beta 2 and iOS 9 beta 2

Installing watchOS 2 beta 2 on my Apple Watch

As many people including myself noticed, iOS 9 beta 1 and watchOS 2 beta 1 had horrible battery life. After two weeks of bearing this, beta 2 of both OSes arrived on June 23 (June 24 in Korea), amidst the hope that they would fix or lessen this battery problem. The one for Apple Watch was pulled just after release, but then re-uploaded a few hours later. I was able to have these betas installed on my iPhone 6 Plus and my Apple Watch as soon as I could.

It's now been more than two full days since and Apple Watch has finally been launched in Korea with people lining up in front of the store despite the rain. For those people who were now wondering if the new beta is anything worth diving into for their shiny new watch, here's my verdict. Yes, it's better than 2.0 beta 1, but no, it's not quite as battery-efficient as 1.0.1. As for the iOS 9 beta 2, its battery life is back to being as good as 8.3 for my iPhone 6 Plus, which was excellent.

This is good news for iPhones, but for Apple Watch, sticking to a non-beta version is still recommended if you value long battery life. As you've seen before, 1.0 / 1.0.1 version delivered about 26 hours of continuous usage on average for me, which included daily exercising and moderate interactions. 2.0 beta 1 effectively halved this, often getting only 12 hours and conservative use barely pushing it to 18 hours. So I'd say that's roughly 15 hours per charge, to be generous. With 2.0 beta 2, I've been getting about 21 hours of use daily so far, barely good enough for one-charge-a-day routine but lacking any comfortable margin.

Meanwhile, the apps do run smoother again, almost like 1.0.1, making the experience less annoying overall. There are still some noticeable bugs, like the one that prevents scrolling with digital crown in certain notifications. This has been persisting since beta 1. Another problem I am seeing is that the voice call volume is quite low and rebooting doesn't fix it. This one seems to be new for this beta. Anyone who's seeking cutting edge, beware.

45 days with Apple Watch & watchOS 2

There's a small scratch on the lower right corner of my Apple Watch

As it's about a week away from Apple Watch's official launch in Korea (and other 2nd wave countries), I wanted to provide an update on the current state of my watch. This is to hint at its durability and upcoming functions.

On the durability side, things are more or less as expected. As I went traveling in New Zealand, the watch accidentally brushed with the walls of the buildings a few times while walking around. It left two slight scratches, one on the aluminum frame and one the glass. The latter is nearly invisible unless seen at a right angle under a bright light. Sapphire glass would've fared even better, but the ion-hardened one on this Sport version seems to be alright, too, given that's all it's gotten after kisses with rough surface.

Area on the band with lots of rubbings appear bright under the light

As for the band, the front side had no visible changes. The back side had been showing marks where rubbings happened only a few days after wearing, but they had no effect on the functional and performance aspects of the band. So unless you take the watch off your wrist to see the marks, you won't be able to tell the difference from day 1 to day 45 use.

Considering all this, I think Apple Watch Sport should be quite usable for a long time, under normal circumstances. Meanwhile, I also had the chance to explore the upcoming OS, watchOS 2, as WWDC 2015 event unfolded nearly two weeks ago.

Korean-Chinese Lunar Calendar Difference

In the light of the upcoming Chinese lunar calendar support in iOS 8, I've cross-compared the Korean and Chinese lunar calendar data to see where exactly the two calendars differ. The chart below shows the result.

The difference mostly happens one lunar month at a time, during which the Korean lunar calendar trails the Chinese by one day. 2012 had a special case where the lunar month became different, as the Korean one had a leap third month while the Chinese one had a leap fourth month.

The chart covers all dates between 1901 and 2050 by the Gregorian (regular Western) calendar.

If you want to add this information to your calendar, use the following URL:
Lunar Calendar Difference ICS file

Download the ICS file and open up in your calendar app. If you're using Google Calendar, right-click and copy the URL first. Then on the "Other calendars" menu on the left side of the Google Calendar, click the drop-down button on the right and select "Add by URL". You can paste the URL there to add the calendar.

iOS 8's (Chinese) Lunar Calendar Support

 
Lunar Calendar comes to iOS

As noted by Apple on the iOS8 announcement, using lunar calendar on the device will become easier. I'm sure a lot of the Koreans have been waiting for this. Until now, there hadn't been a system-wide support, so a user would have had to use an app that could display and manage this calendar on its own. This hassle should go away when the new iOS version arrives.

Sadly for the Koreans, this lunar calendar is being called "Chinese Calendar" on the system. Of course, if the user knows how to read basic Chinese glyphs, it isn't much of a practical issue. The dates mostly match, and the names of the year based on the sexagenary cycle are identical as well.

But the reason why this can't simply be generalized as "lunar calendar" is because it's based on measurements at Beijing, not Seoul. Because of the differences in latitude and longitude between the two capital cities, the phase measurements of the Moon slightly differ. In fact, the dates were off by a day for about five four months in 2012. Even with these downsides, Koreans end up benefitting from Apple's eager push into the Chinese market.

To use the lunar calendar, go to Settings > Mail, Contacts, Calendars > Calendars and select "Chinese" from the Alternate Calendars. After that, the lunar date will show in Chinese on the Notification Center below the regular date.

Meanwhile, if someone in your contacts keeps the birthday in lunar date, you can select "add birthday" to designate one. After that, the Calendar app will show that person's "Chinese Birthday" on the lunar birthday. I expect that this will be of much use to many Koreans.
