The only thing that I carry is everything

Wearing my all-inclusive belt bag on my waist

Nearly a decade ago, you would have seen me wearing all sorts of gadgets around my waist, as evidenced by this television broadcast. The problem with this was clearly illustrated in that video - it takes a bit of time to put them all on the belt, however useful they may be.

I haven't let go of the carry-them-all attitude, but things have worked in my favour. A lot of the gadgets I had to carry separately were now integrated into a single device (smartphone). That meant less stuff to carry, and I was able to reduce the number of pouches and bags on the belt over the years. I ended up with a phone and an external battery each in a holster, and a bag that held adapters, cables, and other miscellany.

But then large iPhones came along. When I put it on my belt, it occupied a sizable area of my waist. This got me thinking: since the phone is thin enough, maybe I could put it in a belt bag that can store other stuff with it. And this is how I now just have this one bag hanging from my waist.

As you can see here, my iPhone 6S Plus and the slim external battery fit nicely into the front pockets of the bag. They're accessible by opening up the flap usually held in place with a hook-and-loop fastener. I also have a paper clip there in case I need to change the SIM card or poke a reset button.

Of course, there's a lot more hiding behind. Let's take a look at the rear compartment.

Comparing 7 iPhones: Battery (Part 2 of 2)

Shortly after finishing the battery tests for the earlier post, iPhone 4S and later generations received the iOS 9.1 update. Then the thought crossed my mind that I should have tested the "Low Power Mode" introduced with iOS 9. It's a feature touted as enabling you to use the phone up to an hour more by cutting off some background activities, reduce the screen brightness, and slow down the processor. Would it equally benefit different generations of the iPhones? I ran the GeekBench 3 again to find out.

Here, the only major differentiating factor would be the processor speed because the iPhones were in airplane mode and the screen brightness was manually set to lowest like the previous tests. I did re-run the tests for the 'normal' mode because the iOS version was changed from 9.0.2 to 9.1. And as always, the values are normalized to the designed battery capacity.

Power Mode iPhone 4S iPhone 5 iPhone 5S iPhone 6 Plus iPhone 6S Plus
Default 04:29:00 02:59:20 02:25:00 05:01:10 07:56:10
Low Power 04:26:30 04:36:20 03:40:10 07:15:10 10:34:00

This revealed that Apple's claims were not overblown. With the exception of iPhone 4S, the iPhones indeed lasted significantly longer under Low Power Mode: about one and a half hours with 5 and 5S, and about two and a half hours with the Plus phones, which are around 30 to 50% gain. It seems that the processor is clocked down to squeeze out as much battery time as possible. On the other hand, the processor for 4S can't seem to throttle back for this mode, resulting in practically no changes. This means that for 4S, the real-life battery savings would have to come from other tweaks.

And if we measure how much work is done with each mode, it gets more interesting. It confirms that the 4S isn't doing anything different, while iPhone 5 seems to fully trade battery time for speed. Meanwhile, the newer generations are able to do more work under the Low Power Mode. This means that if the tasks you do a lot on your phone isn't impacted too much by this mode, it might not be a bad idea to keep this mode on while you do those things if you want to maximize battery life.
