\r\n\r\nAnother day, another iPhone case. \u00a0Well, in truth, another iPhone battery case that is compatible with both the 5 and 5s. \u00a0If you ask me, a battery pack for a smartphone is a must have. \u00a0And not just for the purpose of charging your phone on the go. \u00a0They're extremely handy around the house, as they negate the need to leave your phone tethered to a wall or a computer. If you want to compare with another battery case, take a look at our Ventev Powercase 2000 review.\r\n\r\nSo today I'm looking at Odoyo's iPhone 5\/s battery case. \u00a0Specs state that it sports at 2,200mAh battery, which is almost 800mAh more than the iPhone 5s's built-in battery. \u00a0Impressive, but rarely does this actually translate to actual use time (more on that later). \u00a0Other features include a kickstand, an LED light that glows three different colors to indicate remaining charge, and an on\/off switch.\r\n\r\nLike Mophie's line of battery packs for the iPhone, Odoyo's also charges via microUSB. \u00a0I find this extremely convenient since microUSB cords are far more ubiquitous and cheaper than the iPhone 5 and 5s's Lighting cable. \u00a0Odoyo\u00a0points out that you can sync your iPhone 5s to your computer using this port - a moot concern for me since I never sync my phone by cord.\r\n\r\nMade up of two parts - a battery pack and a frame - the\u00a0Odoyo\u00a0EX can be a bit fiddly, at least when compared to competitors. \u00a0First, the\u00a0iPhone 5 or 5s must be inserted. \u00a0Simple enough. \u00a0Then a frame must be fitted around it and snapped into place. \u00a0Easy, but you'll want to ensure it snaps completely into place by pressing on all four corners. \u00a0This is the part that is more laborious than Mophie's cases, which generally speaking are just two parts. \u00a0That said, lose the frame and you can still use the battery pack.\r\n\r\n\r\n\r\nThe frame and battery pack of the Odoyo EX provide reasonable protection from dings, scratches and the occasional drop. \u00a0I have to wonder what would happen if my iPhone 5s took a serious fall to the floor, but since I'm not willing to test this out I can't tell you.\r\n\r\nWhat I can tell you is that sound is channeled forward (and into the handset) thanks to a set of slots on the base of the phone. \u00a0Callers never complained of any sound interference while the Odoyo EX battery case was in use.\r\n\r\nLooking to the back there is the familiar cut outs for the iPhone 5s's camera, as well as a port for the headphone jack. \u00a0However, since the headphone jack is on the bottom of the iPhone 5 and 5s, the hole is fairly deep and for most headphones you'll need the included headphone jack extender. \u00a0Annoying since it's another thing to carry around. \u00a0And given its small size, you're likely to lose it.\r\n\r\nFurther down the back is a kickstand and power button to turn the case on and off. \u00a0At first the kickstand was very difficult to extend, but after some use loosened up - just watch your fingertips, at least initially. \u00a0 The power button, however, is almost useless, since it can be inadvertently pressed by sticking it in your pocket or laying it down flat against a hard surface. \u00a0For some this won't matter. \u00a0But for others, who'd like to achieve the optimal amount of charge by turning the battery case on when the phone's batter is low, this might be a cause for concern.\r\n\r\nAll together I'm pretty pleased with the Odoyo EX battery case for the iPhone 5 and 5s. \u00a0Its 2,200mAh battery generally nets me about 80% more battery life, which is a bit less than I expected given the battery's capacity. \u00a0But this seems to be par for the course in all my experiences with battery packs for the iPhone or Android devices. \u00a0I would rather a soft rubber finish (instead of the hard plastic seen here), since that seems to provide added protection and a all together nicer\/grippier feel in the hand.
