Today’s high-end smartphones are powerful beasts with multi-core processors, 1080p (or higher!) displays, and other components that blow away the devices of yester-year. Of course with great power comes great battery drain, and so today’s smartphones see ever increasing battery sizes.

Turning to the Samsung Galaxy S5, we find a 2800 mAh battery designed to get you through a full day’s worth of moderate use. But what if you want more? Thankfully, the Galaxy S5 has the advantage of a removable battery, allowing you to swap in something even larger like Mugen’s new 5,900 mAh battery.

At $89.50, the Mugen Power extended battery isn’t exactly cheap, but it essentially delivers a little over double the battery life originally provided by the GS5, while also coming with support for NFC and QI wireless charging. On the downside, the battery and accompanying back cover will not offer water-resistance, though Mugen is reportedly working on a waterproof version for future release.

The Mugen Power extended battery can be ordered now directly through Mugen, though it’s important to note that the battery and cover won’t actually ship until June 6th. You’ll also have the choice between a black or white battery cover.
