Problem 1: Continuous use of your phone’s GPS functionality quickly drains its reserves.
Problem 2: iPhones are fragile.
Solution: The latest Mophie Juice Pack, a burly update of the version that won a 2010 Editors’ Choice Award. “I shot four days of photos and videos on a single charge in Chile,” raves our gear editor. “That’s almost double the previous performance.” The Juice Pack’s rechargeable lithium-polymer battery (thinner and lighter than traditional lithium-ion batteries) brought another editor’s dying iPhone back to full power in less than three hours deep in the backcountry, even though her phone was simultaneously running a navigation app in the background. The plastic housing has a soft-touch coating for solid grip, and a TPU band around the edge increases impact protection.
“I fumbled my phone while trying to snag a photo on a blustery ridgeline at 10,000 feet,” says our gear editor. “No nicks.” The case attaches to the iPhone at the bottom through Apple’s standard 30-pin connector, and a small switch allows you to toggle between standby and charging modes. Testers also liked that they could check the Juice’s battery life by pressing a button that ignites LEDs (four lights means fully charged).
Bonus: The Outdoor Edition comes with a one-year subscription to Mophie’s Outdoor nav app ($30 value), which lets you record tracks and waypoints, geotag photos, search for nearby trailheads and points of interest, and cache AccuTerra topo maps for offline viewing. Cons: The case isn’t waterproof, there’s no screen protector, and it’s only compatible with iPhone 4 and 4S. A $19/year subscription is required to continue using the app after the first year. $120; 3 oz.; mophie.com
Warranty Issues!
I enjoyed the unit for just under a year when the micro USB socket wouldn't accept a charge (broke). I telephoned the company within two weeks of warranty expiration (one year) and I received a letter after the expiration date that stated the unit was no longer covered under warranty.
I then checked Amazon and 'New Trent' now sells a 2400 mAh polymer lithium for half the price and it works great! Also, the charging cable is mini USB to USB and plugs directly into any USB port. 'New Trent' also sells a very packable 11.1 Ah lithium polymer battery to recharge any small electronics you may carry. As well, they have no problem exchanging a defective item!

Before you spend big bucks on a fancy phone charger; look online for good prices on the exact battery your phone uses, then order 6 or more spares and charge them at home before your trip. You can also find cheap 110/220V chargers online for about $5 that will charge any cell battery out of the phone. My phone is not a smart phone, so not sure how much more other batteries cost, but I got exactOEM spares for mine for about $6 each

@Edwin: iPhone batteries are not removable.
