Your iPhone has likely all but become an extension of yourself these days; if only its built-in battery could last as long as you do. For those who are out and about but don't want to be weighed down, the $79 Mophie Juice Pack Helium adds just 2.5 ounces to the weight of your iPhone, but promises as much as 6 hours more of endurance. Read on to find out whether Mophie's latest and greatest accessory gives you enough juice for your money.
On the bottom of the Helium is a large opening for the headphone jack (an included extender cable is required to plug in your headphones). Around back is an on/off switch, four power indicator LEDs and a tiny button that turns them on. The case charges through a microUSB port found where you would normally plug in a Lightning charge cable.

Following Mophie's involved instructions, we were able to get a Verizon iPhone 5 to last 8 hours and 40 minutes on the LAPTOP Battery Test (continuous Web browsing over LTE). That's an increase of just 3 hours and 10 minutes, and less than all the other iPhone battery cases we've tested. This runtime is 26 minutes less than the average, and 20 minutes less than the i-Blason PowerGlider and myCharge Freedom 2000. The heavier Lenmar Meridian lasted 10:05, while the bulky iBattz Mojo Hi5 Power Bank lasted 12:54.
Mophie warns that, like with all lithium polymer batteries, this battery will recharge for more than 500 cycles. After that, the battery inside might provide less than 75 percent of its original capacity.
The $99 Mophie Juice Pack Air, which has a 1700-mAh battery, should provide an extra hour or two of endurance, but weighs a slightly heavier 2.68 ounces.
