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.
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

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!

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

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!
