Tips: Stretching an iPhone 5 Battery Through a 6 Day Hike in Yosemite National Park

This will be a quick one folks! I just wanted to share how I made a stock iPhone 5 battery stretch 6 days on one full charge while using it only as a camera.

When traveling, I really love using my iPhone as my main point-and-shoot. Does it best my wife’s DSLR? Hell no, not even close. But it does take decent photos if you’ve mastered its quirks and the portability of it is second-to-none.

Upper Cathedral Lake

But what about on hiking trips? Not car-camping mind you, but hiking out in the middle of nowhere, where the nearest power outlet is literally days away?

In those cases you could either bring one of the many portable solar chargers that are now available at any camping/outdoor gear store, or even a hand-crank generator, but that’s just extra weight for me to lug around, not to mention misplace or lose. So when my week-long hike in Yosemite came along, I wanted to see just how far I could stretch a single charge on my iPhone 5, all while using it to snap frequent pics of the stunning beauty out there (and man, there is SO much!).

Now, on a typical day I use my phone to such a degree that I rarely get through a full 24 hour period without plugging it in. I am sure many of you can relate. So how did I accomplish 6 days straight? Let me tell you!

Dim Your Screen Brightness

Brightness Settings

Go under “Settings” and tap “Brightness & Wallpaper”. In that menu, use the slider to bring your brightness down to 50% (or as low as your poor eyes can stand).

Airplane Mode is Your Friend!

Turn off Airplane Mode

Tap “Settings” (if you aren’t still in there) and right up at the top you’ll see a toggle for “Airplane Mode”. Turn this bad boy on and leave it. This turns off your cellular service, WIFI and your Bluetooth connectivity. With this turned on, your phone stops continuously looking for something that, out in the middle nowhere, it will never find. If it was constantly searching? Your battery would be dead in way less than a day. So at the very least, switch Airplane Mode to the “on” position.

Turn Off Location Services

Turn Off Location Services

Tap “Settings” again, go down to “Privacy” and in there you will find “Privacy Services”. Click on that and hit the toggle at the top to turn that off. You will lose the geolocation of the pictures you snap, but the accuracy of that gets dodgy anyways when you are that far off of the grid.

Basically an iPod Touch…

That’s all I turned off! With all these services off, you’ve basically got an iPod Touch, but you can still utilize your camera (which I used continuously from the slider on the lock screen), snap a pic, check it out and lock the phone immediately afterward.

So how did this all work? Quite well! So well in fact that I took well over a hundred shots (a bunch of panoramas too) and, with less than 48 hours until I was back in civilization, I still had 50% battery left! I know! Not bad!

I am sure a lot of folks have tried this combo with varying degrees of success, but sometimes it’s good to read about a use case that actually occurred and worked. If there are any other services I missed let me know!

A Bit on Common Sense

I know it goes without saying but… I when I was hiking, I was with 4 other people who all had charged phones, compasses and maps on them… in other words: don’t take chances. If your phone is the only thing you have as a link to possible rescue, don’t try this out. It’s not worth it.

But, if you are properly prepared, I whole-heartedly recommend leaving your iPhone charger back in the car.

Out there it’s not going to do you any good anyways. ;)

Have fun and be safe!

Hardware: Review of Logitech’s K750 and K760 Wireless Solar Keyboards

Apple Bluetooth Keyboard

For the last few years, I have been using my ever-faithful Apple bluetooth keyboard for my wireless keyboard needs (Laptop, iPad, iPhone, Mac Mini, you name it…). I chose it for the following reasons:

  1. It’s got a good form factor
  2. It is ruggedly built (I have dropped it several times and it has kept ticking without a hitch).
  3. Despite it’s form factor it has got a full size layout for its keys (sans number pad). Which is always important. I hate feeling cramped while typing.
  4. It pairs relatively easily with devices and the Mac-specific hotkeys at the top are quite quite handy (particularly when used with the iPad)
  5. It’s easy to grab and slide into my bag when I need to just go.

But, that all said, there are a few drawbacks. Small stuff mostly, but chief amongst them is the Apple keyboard’s need of batteries to function and it’s ability to have it’s bluetooth connection turned on by accident (draining the batteries of both your device and the keyboard) if the large button on its side gets touched by a feather.

Both of these issues caused me to reevaluate my selection of a keyboard and at least start to research what is out there nowadays for alternative options. Suffice it to say, I found a lot!

 

The best options built specifically for the Mac, that weren’t built by Apple, seemed to be offered by Logitech. They have a great selection with a lot of options, but in the end I settled on their series of solar powered keyboards. They support all of the current Apple command key shortcuts, have zero need for batteries (fully charged, it can be used for three continuous months in complete darkness) and, in the case of the travel version, they have the ability to hot swap between multiple bluetooth devices. Which is handy if you need to quickly disconnect from one device and quickly pair with another (from an iPad to a desktop, for instance).

Here are the two I went with:Logitech K760 Wireless Solar KeyboardFor the iPad I went with the Logitech Wireless Solar Keyboard K760

Logitech K750 Wireless Solar KeyboardAnd for the Mac Mini I splurged and snagged the full sized Logitech Wireless Solar Keyboard K750 for Mac®

They both perform easily as well as their Apple manufactured counterparts and while they don’t feel as well built as Apple’s aluminum keyboards, they by no means feel cheap in any way.

Function-wise, they both have worked flawlessly. I love that the hotkeys (the “F” keys) that are in the top row of the Apple keyboard, can all be found on the Logitechs (the media-based buttons work even on the iPad!). Also, eco-stance aside, I really love that I don’t have to worry about having my rechargeable batteries around and charged up when my keyboard dies. The solar cell at the top, does change the footprint (and the aesthetic if that’s important to you) obviously, making the keyboard, in both cases, taller. But the exchange for battery life and the simple convenience of putting it in any kind of light to recharge it, definitely trumps these quibbles for me.

The bluetooth hot swapping on the K760? It works as advertised and is pretty damn amazing! Once paired up (easy to do as well) I was swapping between my iPad, iPhone and Macbook with a simple keystroke. It’s fast and way more convenient than I originally anticipated. Definitely not a gimmicky feature! It is the real deal and quite helpful.

One odd difference between the two? The K760 keys are WAY more “clicky” than the K750. So if you are into that, or are obsessive about stealth typing, than you may want to take a note of this. I noticed it right away.

Lastly, the K750 comes with a free app you can snag from the Mac App Store that gives you real time info on your charge and the amount of light/solar energy your keyboard is currently receiving. Pretty neat to bring up and watch, not to mention handy if you need to know how much juice your keyboard currently has left. Again, it’s only for K750, but it is well implemented on the Mac.

So if it wasn’t clear enough yet, I will come out and say it: I am pretty smitten with these keyboards! I’ve used the K750 for a month now and the K760 for a little over week. They have not given me one bit of buyer’s remorse. Quite the opposite actually. I wish more peripherals were made with this kind of utility and function.

Two thumbs up! Way up! Highly recommended!
