Background
Unless you’ve been living in Vega, Texas, you’ve probably heard the iPhone does not have a replaceable battery, meaning you can’t bring a second (or third etc.) to pop in that iPhone when you run out of juice, like you can with a notebook computer.
I just got back from a 3-day camping-at-night roadtrip, and I had my iPhone on me. Here’s what I learned about power management.
iPhone Travel Tips
So what can you do on the road? Here’s some quick tips:
- bring a car charger Pretty simple stuff. We had a Belkin iPod charger that worked fine for my iPhone. It’s just slow to charge the iPhone.
- bring your wall charger and grab AC power whenever you can The iPhone recharges much faster from AC wall power than it does from a car charger. As few as 15 mintes can give you a 1/4 to 1/3 charge. We’d stop at restaurants and I’d find an AC outlet and pop the phone in it.
- turn off WiFi while driving You won’t need it, and it sucks juice.
- dim the display I had mine on auto-dim, and realized I could really conserve battery by turning this off and moving the slider as far left as I could stand.
Next time I’ll come equipped with a solar charger, an external USB phone charger, or both. Fighting for car charger time (vs. another iPhone owner and an ancient MP3 player) was no fun.

I use a Griffin device for my iPod Touch called Tunejuice: http://www.griffintechnology.com/products/tunejuice2
Maybe you could use this on the iPhone as well?
