Wesley's Tool-Box

- or, why do I get "too much power" error with my drive and how do I fix it? -

With iOS 13, native support of USB external storage was introduced to iPhones. Files stored externally can be accessed from the Files app included in the OS. Other apps can do it as well if it can connect to this Files app. Sadly, modern iPhones' external port of choice is Lightning, which means you either buy a storage device with a Lightning port or get an adapter to connect a USB device. This is where things get complicated.

I bought a Lexar MicroSD to Lightning Reader (part # LRWMLBNL) more than three years ago. It connects directly to the Lightning port and I can open files using a dedicated app. Apple MFI certified storage can supposedly work with the iOS 13's Files app, but that wasn't the case here despite the certification. Adding insult to injury, its app had not been updated in more than two years - the screen resolution and the file sharing functions were outdated. I needed a different solution.

Apple sells many types of USB adapters, one of which is the Lightning to USB Camera Adapter you see above (US$29). It can be connected to a camera for transferring photos and videos, hence the name. Other devices could be plugged in as long as the OS recognizes it, like keyboard, MIDI equipment, or Ethernet adapter. iOS 13 expands this to general storage and mouse.

So I bought this adapter expecting that any low-power storage devices like USB flash drives and memory card reader could be plugged in directly for my file management uses. Boy was I so wrong. Of the multitudes of flash drives and card readers I own, all of them, save for one, caused the "too much power" error you see here. This was bizarre because they shouldn't consume enough power for this to appear. There had to be a reason and a way around this, so I decided to dig in.

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.

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.


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.
