John Gruber commented on using the Apple Watch overnight.

I think sleep tracking is an inevitable feature for Apple Watch. I’ve been wearing a Series 2 to sleep lately, and I wake up with between 55-65 percent battery remaining. I can usually get to a full charge — or close enough, like say 98 percent — just by charging it while I shower and get dressed. In my use, Series 2 does not need to charge overnight. So it might as well track my sleeping.

I’m using a Series 1 and it goes through the day draining about 80%. From experience, I can fully recharge the watch within an hour and a half. This means it is possible to wear the watch overnight as long as I can find a time slot to allow the watch to recharge before I sleep.

The Financial Times interviewed Bill Gates. The article is a good read, including two interesting responses regarding China.

On the rise of China:

I get just a hint of his politics, however, when we discuss the speed and energy with which China is developing and I suggest that some might find it all a bit scary. The word sets Gates off: “If all you care about is the US or the UK’s relative strength in the world, then it’s particularly scary,” he says laughing sarcastically. “In the US case, 1945 was our relative peak.” Since then, as he points out, other countries from Europe to Asia have rebuilt and become more prosperous, but, says Gates, “I guess I’m just not enough of a nationalist to see it all in negative terms.” On the contrary, Gates is excited by the things that a richer China could bring to the world. “I think it’s good that Chinese scientists are working on cancer drugs, because if my kid got cancer, I wouldn’t look at the label that says ‘made in China’. And, hopefully, we’ll get them working on some of these vaccines and also on energy.”

On China’s impact on the environment:

But Gates is also worried about the environment, so I ask him if the rapid industrialisation of China is a recipe for environmental disaster. Again, his impulse is to look to technology for a solution: “Short of going to war over this issue, the best way would be to find innovative forms of energy generation”. He is excited by solar and nuclear energy, and mocks those who complain about rising Chinese energy use — “I mean, these Chinese are actually using as much energy per capita as the average in the world today, how dare they! How did that happen? The US uses four times the average and the Brits double. But now these Chinese are trying to use the average.”

MacRumors reported on AirPods capturing one quarter of wireless headphone spending since launching.

In the U.S. last month, an estimated 75% of revenue from headphones sold online came from wireless models, up from 50% in December 2015, according to Slice Intelligence. Apple’s new AirPods led the way, capturing an estimated 26% share of online revenue in the wireless headphone market since launching on December 13.

AirPods stole the top spot from Beats, which took an estimated 15.4% of online revenue in the wireless headphone market, down from 24.1% between the start of 2015 and December 13. Given it owns Beats, Apple appears to have actually taken nearly 40% of online revenue in the market since launching AirPods.

Other than hardcore audiophiles, most users would find wireless headphones a more convenient option. With EarPods so commonly used, the trend would favour a shift to increasing AirPods adoption as users switch to wireless headphones.

Emojipedia wrote about Android’s Emoji Problem.

The Google design team had a head start over Apple in terms of emoji adoption.

Unicode 9 support was first added to Android 7.0 in August, followed by genders and professions which arrived with 7.1 in October 2016. This was some timely updating from Google, especially compared to previous years.

By contrast, iOS didn’t include any new emoji updates until iOS 10 in September. The rest of the new emojis came months later in iOS 10.2 in December 2016.

However, real world usage shows that Android is lagging behind Apple.

Just 4% of Android users are using any variation of 7.x Nougat (released in August-September 2016), resulting in 96 out of 100 Android users not seeing the latest emojis.

In contrast, 84% of iOS users who visited Emojipedia are on iOS 10.

Google’s own statistics on Android version share show worse results with under 1% using Android 7.0 Nougat.

As a result, apps are taking matters into their own hands to make emojis work on Android.

Snapchat, Messenger, WhatsApp, Telegram and Slack all use emoji-replacement images on Android; in a trend started by Twitter with Twemoji which was released when the most popular browser on Windows (Chrome) didn’t include emoji support.

WhatsApp and Telegram even use Apple’s own emoji images on Android, and makes a custom keyboard to display them

Reuters reported on U.S. appeals court reviving antitrust lawsuit against Apple.

But if the challenge ultimately succeeds, “the obvious solution is to compel Apple to let people shop for applications wherever they want, which would open the market and help lower prices,” Mark C. Rifkin, an attorney with Wolf Haldenstein Adler Freeman & Herz representing the group of iPhone users, told Reuters in an interview. “The other alternative is for Apple to pay people damages for the higher than competitive prices they’ve had to pay historically because Apple has utilized its monopoly.”

Because $0.99 is too expensive a price to pay for protection against malware and bad apps.

9to5Mac reported on Apple being on track to hit $1 trillion in total revenue from iOS by the middle of this year.

Last year, some analysts made the unlikely claim that Alphabet or Amazon might beat Apple to be the first trillion-dollar company. Asymco’s Horace Dediu, however, is out today with a new report predicting that Apple will cross the $1 trillion mark this year in terms of revenue generated by iOS, pushing it closer to a$1 trillion market cap.

Icing on the tenth anniversary birthday cake.
