I plan on updating a blog using my Galaxy S3 nearly everyday while thru-hiking this year — or that's my hope. How easy is it to keep a phone charged, assuming it's turned off mostly all the time except for when I'm writing?
Also: I have an extended custom battery (7000 mAh vs the stock 2100) that adds a bit of bulk and weight with the benefit of basically tripling the battery life. One drawback with this battery is that it takes FOREVER to fully charge if it's dead — I'm talking more than 12 hours. Say I'm staying at a hostel every now and then, can I be pretty sure that I'll have an outlet to myself overnight? I'm not sure it'll even be worth bringing the big battery since I don't plan on staying stationary long enough to charge it.
Any thoughts from those who aren't ditching electronics on the trail? I'm also planning on bringing a GoPro, which will require charging too, but I'll be able to do that simultaneously with the phone.
