Back in September, Mophie launched two brand-new battery products, the Juice Pack Reserve, a $59.95 battery case for the iPhone 6 and 6s, and the Power Reserve 1X, a small $34.95 external battery for smartphones and wearables. I have been testing both for the past two weeks in regular daily use and at a wedding, an environment that tends to be more smartphone-intensive than a typical day.
Mophie says the Juice Pack Reserve is the most compact battery case it’s ever created, adding just 0.3 inches of thickness and 75 grams of weight to the iPhone 6 or 6s. In my testing, I found that Mophie’s claim that the case is in a form factor that “you’ll barely notice” is mostly true, although with a caveat. Its soft-touch back provided a comfortable and easy-to-grasp grip despite feeling noticeably more dense. However, the case’s lower lip, where the speaker grille resides and the case plugs into the iPhone, is far more noticeable and users not accustomed to the extra length will have to spend some time acclimating to it when scrolling or typing.
The case’s extra mass was not a hindrance when attemtping to quickly capture moments at the wedding though, as it slipped in and out of tuxedo pockets fairly easily. In fact, the in-pocket feel of the case was barely noticeable in tuxedo pants, even during more intensive activites like dancing. The extra mass of the case is, however, more obvious visually. In more regular daily use, the case was even less of a hindrance.
