Incase has unveiled the Power Slider, a case for the iPhone 3G that also contains an extended battery. The case is designed to drain its own battery first, then leaves the user with a fully charged phone. The hard-shell construction protects the entire phone, while a soft-touch coating offers improved feel and grip. The 1330 mAh lithium-polymer battery is claimed to increase standby time by 330 hours, audio playback by 26 hours, and internet use by five to six hours. Talk time on the 3G network increases by five hours, while talk time on the 2G network is extended by ten hours.
The Power Slider offers higher capacity than the USBfever 1000mAh Handy Battery Pack, while also adding an LED status indicator and the ability to sync while the phone is encased. Mophie's Juice Pack integrates an 1800 mAh battery, slightly outperforming the Incase product, but does not protect the whole phone.
The Power Slider will be available closer to the holidays, from Incase, Apple retail or online stores, and Best Buy. The case carries a suggested price of $100.
